ALABAMA POWER COMPANY
2018 ANNUAL REPORT
MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Alabama Power Company 2018 Annual Report
The management of Alabama Power is responsible for establishing and maintaining an adequate system of internal control over
financial reporting as required by the Sarbanes-Oxley Act of 2002 and as defined in Exchange Act Rule 13a-15(f). A control
system can provide only reasonable, not absolute, assurance that the objectives of the control system are met.
Under management's supervision, an evaluation of the design and effectiveness of Alabama Power's internal control over
financial reporting was conducted based on the framework in Internal Control—Integrated Framework (2013) issued by the
Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that
Alabama Power's internal control over financial reporting was effective as of December 31, 2018.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the stockholders and the Board of Directors of Alabama Power Company
Opinion on the Financial Statements
We have audited the accompanying balance sheets and statements of capitalization of Alabama Power Company (Alabama
Power) (a wholly-owned subsidiary of The Southern Company) as of December 31, 2018 and 2017, the related statements of
income, comprehensive income, common stockholder's equity, and cash flows for each of the three years in the period ended
December 31, 2018, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial
statements present fairly, in all material respects, the financial position of Alabama Power as of December 31, 2018 and 2017,
and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in
conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of Alabama Power's management. Our responsibility is to express an opinion
on Alabama Power's financial statements based on our audits. We are a public accounting firm registered with the Public
Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to Alabama
Power in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and
Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to
error or fraud. Alabama Power is not required to have, nor were we engaged to perform, an audit of its internal control over
financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting
but not for the purpose of expressing an opinion on the effectiveness of Alabama Power's internal control over financial
reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due
to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis,
evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting
principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial
statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as Alabama Power's auditor since 2002.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Alabama Power Company 2018 Annual Report
OVERVIEW
Business Activities
Alabama Power operates as a vertically integrated utility providing electric service to retail and wholesale customers within its
traditional service territory located in the State of Alabama in addition to wholesale customers in the Southeast.
Many factors affect the opportunities, challenges, and risks of Alabama Power's business of providing electric service. These
factors include the ability to maintain a constructive regulatory environment, to maintain and grow energy sales and customers,
and to effectively manage and secure timely recovery of costs. These costs include those related to projected long-term demand
growth, stringent environmental standards, including CCR rules, reliability, fuel, capital expenditures, including improving the
electric transmission and distribution systems, and restoration following major storms. Alabama Power has various regulatory
mechanisms that operate to address cost recovery. Effectively operating pursuant to these regulatory mechanisms and
appropriately balancing required costs and capital expenditures with customer prices will continue to challenge Alabama Power
for the foreseeable future. On May 1, 2018, the Alabama PSC approved modifications to Rate RSE and other commitments
designed to position Alabama Power to address the retail rate impact and the growing pressure on its credit quality resulting from
the Tax Reform Legislation. See FUTURE EARNINGS POTENTIAL – "Retail Regulatory Matters" and FINANCIAL
CONDITION AND LIQUIDITY – "Credit Rating Risk" herein for additional information.
Alabama Power continues to focus on several key performance indicators including, but not limited to, customer satisfaction,
plant availability, system reliability, and net income after dividends on preferred stock. Alabama Power's financial success is
directly tied to customer satisfaction. Key elements of ensuring customer satisfaction include outstanding service, high reliability,
and competitive prices. Management uses customer satisfaction surveys to evaluate Alabama Power's results and generally targets
the top quartile of these surveys in measuring performance.
See RESULTS OF OPERATIONS herein for information on Alabama Power's financial performance.
Earnings
Alabama Power's 2018 net income after dividends on preferred and preference stock was $930 million, representing an $82
million, or 9.7%, increase over the previous year. The increase was primarily due to a decrease in income tax expense, partially
offset by a decrease in retail revenues associated with customer bill credits related to the Tax Reform Legislation. The increase
also reflects an increase in revenues associated with colder weather in the first quarter 2018 and warmer weather in the second
and third quarters 2018 compared to the corresponding periods in 2017, partially offset by an accrual for a Rate RSE refund. See
FUTURE EARNINGS POTENTIAL – "Retail Regulatory Matters – Rate RSE" herein for additional information.
Alabama Power's 2017 net income after dividends on preferred and preference stock was $848 million, representing a $26
million, or 3.2%, increase over the previous year. The increase was primarily due to an increase in rates under Rate RSE effective
in January 2017 and the impact of a Rate RSE refund recorded in 2016. These increases to income were partially offset by a
decrease in retail revenues associated with milder weather, lower customer usage, and an increase in non-fuel operations and
maintenance expenses in 2017 as compared to 2016. See FUTURE EARNINGS POTENTIAL – "Retail Regulatory Matters –
Rate RSE" herein for additional information.

Retail revenues in 2018 were $5.4 billion. These revenues decreased $91 million, or 1.7%, in 2018 as compared to the prior
year. The decrease in 2018 was primarily due to customer bill credits related to the Tax Reform Legislation and an accrual for a
Rate RSE refund, partially offset by an increase in fuel revenues and colder weather in the first quarter and warmer weather in
the second and third quarters 2018 as compared to the corresponding periods in 2017.

MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
Retail revenues in 2017 were $5.5 billion. These revenues increased $136 million, or 2.6%, in 2017 as compared to the prior
year. The increase in 2017 was primarily due to an increase in rates under Rate RSE effective in January 2017, partially offset
by a decrease in fuel revenues and milder weather in the first and third quarters 2017 as compared to the corresponding periods
in 2016.
See Note 2 to the financial statements under "Alabama Power – Rate RSE" for additional information. See "Energy Sales"
herein for a discussion of changes in the volume of energy sold, including changes related to sales decline and weather.
Electric rates include provisions to recognize the recovery of fuel costs, purchased power costs, PPAs certificated by the
Alabama PSC, and costs associated with the natural disaster reserve. Under these provisions, fuel and other cost recovery
revenues generally equal fuel and other cost recovery expenses and do not affect net income. See FUTURE EARNINGS
POTENTIAL – "Retail Regulatory Matters – Rate ECR" herein for additional information.

Wholesale revenues from sales to non-affiliates will vary depending on fuel prices, the market prices of wholesale energy
compared to the cost of Alabama Power's and the Southern Company system's generation, demand for energy within the
Southern Company system's electric service territory, and availability of the Southern Company system's generation. Increases
and decreases in energy revenues that are driven by fuel prices are accompanied by an increase or decrease in fuel costs and do
not affect net income. Short-term opportunity energy sales are also included in wholesale energy sales to non-affiliates. These
opportunity sales are made at market-based rates that generally provide a margin above Alabama Power's variable cost to
produce the energy.
In 2018, wholesale revenues from sales to non-affiliates increased $3 million, or 1.1%, as compared to the prior year. In 2017,
wholesale revenues from sales to non-affiliates decreased $7 million, or 2.5%, as compared to the prior year.
Wholesale revenues from sales to affiliated companies will vary depending on demand and the availability and cost of
generating resources at each company. These affiliate sales and purchases are made in accordance with the IIC, as approved by
the FERC. These transactions do not have a significant impact on earnings since this energy is generally sold at marginal cost
and energy purchases are generally offset by energy revenues through Alabama Power's energy cost recovery clause.
In 2018, wholesale revenues from sales to affiliates increased $22 million, or 22.7%, as compared to the prior year. In 2018, the
price of energy increased 12.3% as a result of higher natural gas prices and KWH sales increased 10.0% primarily due to an
increase in hydro generation. In 2017, wholesale revenues from sales to affiliates increased $28 million, or 40.6%, as compared
to the prior year. In 2017, KWH sales increased 31.1% as a result of supporting Southern Company system transmission
reliability and a 6.9% increase in the price of energy primarily due to higher natural gas prices.
In 2018, other operating revenues increased $59 million, or 28.4%, as compared to the prior year primarily due to revenues
related to unregulated sales of products and services that were reclassified as other revenues as a result of the adoption of ASC
606, Revenue from Contracts with Customers (ASC 606). In prior periods, these revenues were included in other income
(expense), net. See Note 1 to the financial statements for additional information regarding Alabama Power's adoption of ASC
606. This increase was partially offset by decreases in open access transmission tariff revenues primarily due to a lower rate
related to the Tax Reform Legislation.

Changes in retail energy sales are generally the result of changes in electricity usage by customers, changes in weather, and
changes in the number of customers. Retail energy sales in 2018 were 3.7% higher than in 2017. Residential sales and
commercial sales increased 8.2% and 1.9% in 2018, respectively, primarily due to colder weather in the first quarter and
warmer weather in the second and third quarters 2018 as compared to the corresponding periods in 2017. Weather-adjusted
residential sales were 0.4% lower in 2018 primarily due to lower customer usage resulting from an increase in penetration of
energy-efficient residential appliances. Weather-adjusted commercial sales were 1.0% lower in 2018 primarily due to lower
customer usage resulting from customer initiatives in energy savings and an ongoing migration to the electronic commerce
business model. Industrial sales increased 1.4% in 2018 as compared to 2017 as a result of an increase in demand resulting from
changes in production levels primarily in the primary metals, pipelines, and mining sectors offset by the paper sector.
Retail energy sales in 2017 were 2.3% lower than in 2016. Residential sales and commercial sales decreased 6.1% and 3.4% in
2017, respectively, primarily due to milder weather in the first and third quarters 2017 as compared to the corresponding
periods in 2016. Weather-adjusted residential sales were 1.2% lower in 2017 primarily due to lower customer usage resulting
from an increase in penetration of energy-efficient residential appliances, partially offset by customer growth. Weather-adjusted
commercial sales were 1.3% lower in 2017 primarily due to lower customer usage resulting from customer initiatives in energy
savings and an ongoing migration to the electronic commerce business model, partially offset by customer growth. Industrial
sales increased 1.7% in 2017 as compared to 2016 as a result of an increase in demand resulting from changes in production
levels primarily in the primary metals, chemicals, and mining sectors offset by the pipelines and paper sectors.
See "Operating Revenues" above for a discussion of significant changes in wholesale revenues from sales to non-affiliates and
wholesale revenues from sales to affiliated companies related to changes in price and KWH sales.
Fuel and Purchased Power Expenses
The mix of fuel sources for generation of electricity is determined primarily by the unit cost of fuel consumed, demand, and the
availability of generating units. Additionally, Alabama Power purchases a portion of its electricity needs from the wholesale
market.

(a) For 2018, cost of fuel, generated and average cost of fuel, generated excludes a $30 million adjustment associated with a May 2018 Alabama PSC
accounting order related to excess deferred income taxes. See FUTURE EARNINGS POTENTIAL – "Retail Regulatory Matters – Tax Reform
Accounting Order" herein for additional information.
(b) KWHs generated by hydro are excluded from the average cost of fuel, generated.
(c) Average cost of purchased power includes fuel, energy, and transmission purchased by Alabama Power for tolling agreements where power is generated
by the provider.
Fuel and purchased power expenses were $1.73 billion in 2018, an increase of $180 million, or 11.6%, compared to 2017. The
increase was primarily due to an $81 million net increase related to the volume of KWHs purchased and generated, a $54
million increase in the average cost of fuel, and a $15 million increase in the average cost of purchased power.
In addition, fuel expense increased $30 million in 2018 as a result of an Alabama PSC accounting order authorizing the
amortization of a regulatory liability to offset under recovered fuel costs. See FUTURE EARNINGS POTENTIAL – "Retail
Regulatory Matters – Tax Reform Accounting Order" herein for additional information.
Fuel and purchased power expenses were $1.55 billion in 2017, a decrease of $78 million, or 4.8%, compared to 2016. The
decrease was primarily due to a $67 million net decrease related to the volume of KWHs generated and purchased and a $42
million decrease in the average cost of fuel, partially offset by a $31 million increase in the average cost of purchased power.
Fuel and purchased power energy transactions do not have a significant impact on earnings, since energy expenses are generally
offset by energy revenues through Alabama Power's energy cost recovery clause. Alabama Power, along with the Alabama PSC,
continuously monitors the under/over recovered balance to determine whether adjustments to billing rates are required. See
Note 2 to the financial statements under "Alabama Power – Rate ECR" for additional information.
Fuel
Fuel expenses were $1.3 billion in 2018, an increase of $76 million, or 6.2%, compared to 2017. The increase was primarily
due to a 5.0% increase in the average cost of KWHs generated by coal and a 4.4% increase in the average cost of KWHs
generated by natural gas, which excludes tolling agreements. These increases were partially offset by a 28.3% increase in the
volume of KWHs generated by hydro and a 2.1% decrease in the volume of KWHs generated by natural gas. Fuel expenses
were $1.2 billion in 2017, a decrease of $72 million, or 5.6%, compared to 2016. The decrease was primarily due to a 12.2%
increase in the volume of KWHs generated by hydro, a 5.8% decrease in the volume of KWHs generated by coal, and a 5.5%
and 3.9% decrease in the average cost of KWHs generated by coal and nuclear fuel, respectively. These decreases were partially
offset by an 8.1% increase in the volume of KWHs generated by nuclear fuel and a 4.0% increase in the volume of KWHs
generated by natural gas.
In addition, fuel expense increased $30 million in 2018 as a result of an Alabama PSC accounting order authorizing the
amortization of a regulatory liability to offset under recovered fuel costs. See FUTURE EARNINGS POTENTIAL – "Retail
Regulatory Matters – Tax Reform Accounting Order" herein for additional information.

MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
Purchased Power – Non-Affiliates
Purchased power expense from non-affiliates was $216 million in 2018, an increase of $46 million, or 27.1%, compared to
2017. This increase was primarily due to an 18.9% increase in the amount of energy purchased due to colder weather in the first
quarter and warmer weather in the second and third quarters 2018 as compared to the corresponding periods in 2017 and a 6.6%
increase in the average cost per KWH purchased due to higher natural gas prices. Purchased power expense from non-affiliates
was $170 million in 2017, an increase of $4 million, or 2.4%, compared to 2016.
Energy purchases from non-affiliates will vary depending on the market prices of wholesale energy as compared to the cost of
the Southern Company system's generation, demand for energy within the Southern Company system's service territory, and the
availability of the Southern Company system's generation.
Purchased Power – Affiliates
Purchased power expense from affiliates was $216 million in 2018, an increase of $58 million, or 36.7%, compared to 2017.
This increase was primarily due to a 34.5% increase in the amount of energy purchased due to colder weather in the first quarter
and warmer weather in the second and third quarters 2018 as compared to the corresponding periods in 2017 and a 1.4%
increase in the average cost per KWH purchased due to higher natural gas prices. Purchased power expense from affiliates was
$158 million in 2017, a decrease of $10 million, or 6.0%, compared to 2016. This decrease was primarily due to a 17.2%
decrease in the amount of energy purchased due to milder weather partially offset by a 13.9% increase in the average cost per
KWH purchased due to higher natural gas prices.
Energy purchases from affiliates will vary depending on demand for energy and the availability and cost of generating
resources at each company within the Southern Company system. These purchases are made in accordance with the IIC or other
contractual agreements, as approved by the FERC.
Other Operations and Maintenance Expenses
In 2018, other operations and maintenance expenses decreased $40 million, or 2.3%, as compared to the prior year. Generation
costs decreased $34 million primarily due to fewer outages resulting in lower costs. Employee benefit costs, including pension
costs, decreased $26 million primarily due to lower active medical costs. Customer service costs decreased $10 million
primarily due to cost-saving initiatives. These decreases were partially offset by a $47 million increase in expenses from
unregulated sales of products and services that were reclassified as other operations and maintenance expenses as a result of the
adoption of ASC 606. In prior periods, these expenses were included in other income (expense), net. See Note 1 to the financial
statements under "Revenue" for additional information.
In 2017, other operations and maintenance expenses increased $152 million, or 9.8%, as compared to the prior year.
Distribution and transmission expenses increased $58 million primarily due to vegetation management expenses. Generation
costs increased $38 million primarily due to outage costs. Employee benefit costs, including pension costs, increased $32
million.
See Note 11 to the financial statements under "Pension Plans" for additional information.
Depreciation and Amortization
Depreciation and amortization increased $28 million, or 3.8%, in 2018 as compared to the prior year primarily due to additional
plant in service related to distribution, transmission, compliance-related steam, and other generation production projects.
Depreciation and amortization increased $33 million, or 4.7%, in 2017 as compared to the prior year primarily due to additional
plant in service and an increase in generation-related depreciation rates, effective January 1, 2017, associated with compliance-
related steam projects and ARO recovery, partially offset by a decrease in distribution-related depreciation rates. See Note 5 to
the financial statements under "Depreciation and Amortization" for additional information.
Allowance for Equity Funds Used During Construction
AFUDC equity increased $23 million, or 59.0%, in 2018 as compared to the prior year. The increase was primarily associated
with steam and transmission construction projects. AFUDC equity increased $11 million, or 39.3%, in 2017 as compared to the
prior year. The increase was primarily associated with steam, transmission, and nuclear construction projects. See Note 1 to
financial statements under "Allowance for Funds Used During Construction" for additional information.
Interest Expense, Net of Amounts Capitalized
Interest expense, net of amounts capitalized increased $18 million, or 5.9%, in 2018 as compared to the prior year primarily due
to an increase in debt outstanding and higher interest rates, partially offset by an increase in the amounts capitalized. Interest
14

Alabama Power Company 2018 Annual Report
expense, net of amounts capitalized increased $3 million, or 1.0%, in 2017 as compared to the prior year. See FUTURE
EARNINGS POTENTIAL – "Financing Activities" herein for additional information.
Other Income (Expense), Net
Other income (expense), net decreased $23 million, or 53.5%, in 2018 as compared to the prior year primarily due to an
increase in charitable donations and the reclassification of revenues and expenses associated with unregulated sales of products
and services to other revenues and operations and maintenance expenses, respectively, as a result of the adoption of ASC 606.
See Note 1 to the financial statements under "Revenue" for additional information. Other income (expense), net increased $17
million, or 65.4%, in 2017 as compared to the prior year primarily due to increases in unregulated lighting services and a
decrease in the non-service cost components of net periodic pension and other postretirement benefits costs. See Note 1 to the
financial statements under "Recently Adopted Accounting Standards" and Note 11 to the financial statements for additional
information on net periodic pension and other postretirement benefit costs.
Income Taxes
Income taxes decreased $277 million, or 48.8%, in 2018 as compared to the prior year primarily due to the reduction in the
federal income tax rate, the benefit from the flowback of excess deferred income taxes as a result of the Tax Reform
Legislation, and lower pre-tax earnings. Income taxes increased $37 million, or 7.0%, in 2017 as compared to the prior year
primarily due to higher pre-tax earnings, an increase related to prior year tax return actualization, and an increase in income tax
reserves, partially offset by an increase in state income tax credits. The impact to net income as a result of the Tax Reform
Legislation was not material due to the application of regulatory accounting. See FUTURE EARNINGS POTENTIAL –
"Income Tax Matters – Federal Tax Reform Legislation" herein and Note 10 to the financial statements for additional
information.
Effects of Inflation
Alabama Power is subject to rate regulation that is generally based on the recovery of historical and projected costs. The effects
of inflation can create an economic loss since the recovery of costs could be in dollars that have less purchasing power. Any
adverse effect of inflation on Alabama Power's results of operations has not been substantial in recent years. See Note 2 to the
financial statements under "Alabama Power – Rate RSE" for additional information.
FUTURE EARNINGS POTENTIAL
General
Alabama Power operates as a vertically integrated utility providing electric service to retail and wholesale customers within its
traditional service territory located in the State of Alabama and to wholesale customers in the Southeast. Prices for electric service
provided by Alabama Power to retail customers are set by the Alabama PSC under cost-based regulatory principles. Retail rates
and earnings are reviewed and may be adjusted periodically within certain limitations. Prices for wholesale electric service,
interconnecting transmission lines, and the exchange of electric power are regulated by the FERC. See ACCOUNTING
POLICIES – "Application of Critical Accounting Policies and Estimates – Utility Regulation" herein and Note 2 to the financial
statements under "Alabama Power" for additional information about regulatory matters.
The results of operations for the past three years are not necessarily indicative of future earnings potential. The level of Alabama
Power's future earnings depends on numerous factors that affect the opportunities, challenges, and risks of Alabama Power's
primary business of providing electric service. These factors include Alabama Power's ability to maintain a constructive
regulatory environment that continues to allow for the timely recovery of prudently-incurred costs during a time of increasing
costs and the weak pace of growth in new customers and electricity use per customer, especially in residential and commercial
markets. Earnings will also depend upon maintaining and growing sales, considering, among other things, the adoption and/or
penetration rates of increasingly energy-efficient technologies and increasing volumes of electronic commerce transactions, both
of which could contribute to a net reduction in customer usage. Earnings are subject to a variety of other factors. These factors
include weather, competition, new energy contracts with other utilities, energy conservation practiced by customers, the use of
alternative energy sources by customers, the price of electricity, the price elasticity of demand, and the rate of economic growth or
decline in Alabama Power's service territory. Demand for electricity is primarily driven by the pace of economic growth that may
be affected by changes in regional and global economic conditions, which may impact future earnings.
15
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
Environmental Matters
Alabama Power's operations are regulated by state and federal environmental agencies through a variety of laws and regulations
governing air, water, land, and protection of other natural resources. Alabama Power maintains comprehensive environmental
compliance and GHG strategies to assess upcoming requirements and compliance costs associated with these environmental laws
and regulations. The costs, including capital expenditures, operations and maintenance costs, and costs reflected in ARO
liabilities, required to comply with environmental laws and regulations and to achieve stated goals may impact future electric
generating unit retirement and replacement decisions, results of operations, cash flows, and/or financial condition. Related costs
may result from the installation of additional environmental controls, closure and monitoring of CCR facilities, unit retirements,
or changing fuel sources for certain existing units, as well as related upgrades to Alabama Power's transmission and distribution
systems. A major portion of these costs is expected to be recovered through existing ratemaking provisions. The ultimate impact
of environmental laws and regulations and the GHG goals discussed herein will depend on various factors, such as state adoption
and implementation of requirements, the availability and cost of any deployed technology, fuel prices, and the outcome of
pending and/or future legal challenges.
New or revised environmental laws and regulations could affect many areas of Alabama Power's operations. The impact of any
such changes cannot be determined at this time. Environmental compliance costs could affect earnings if such costs cannot
continue to be recovered in rates on a timely basis. Environmental compliance costs are recovered through Rate CNP Compliance.
See Note 2 to the financial statements under "Alabama Power – Rate CNP Compliance" for additional information. Further,
increased costs that are recovered through regulated rates could contribute to reduced demand for electricity, which could
negatively affect results of operations, cash flows, and/or financial condition. Additionally, many commercial and industrial
customers may also be affected by existing and future environmental requirements, which for some may have the potential to
ultimately affect their demand for electricity.
Through 2018, Alabama Power has invested approximately $5.4 billion in environmental capital retrofit projects to comply with
environmental requirements, with annual totals of approximately $681 million, $491 million, and $260 million for 2018, 2017,
and 2016, respectively. Although the timing, requirements, and estimated costs could change as environmental laws and
regulations are adopted or modified, as compliance plans are revised or updated, and as legal challenges to rules are initiated or
completed, Alabama Power's current compliance strategy estimates capital expenditures of $635 million from 2019 through 2023,
with annual totals of approximately $226 million in 2019, $68 million in 2020, $118 million in 2021, $112 million in 2022, and
$111 million in 2023. These estimates do not include any potential compliance costs associated with pending regulation of CO2
emissions from fossil fuel-fired electric generating units. See "Global Climate Issues" herein for additional information. Alabama
Power also anticipates substantial expenditures associated with ash pond closure and ground water monitoring under the CCR
Rule, which are reflected in Alabama Power's ARO liabilities. See FINANCIAL CONDITION AND LIQUIDITY – "Capital
Requirements and Contractual Obligations" herein and Note 6 to the financial statements for additional information.
Environmental Laws and Regulations
Air Quality
The EPA has set National Ambient Air Quality Standards (NAAQS) for six air pollutants (carbon monoxide, lead, nitrogen
dioxide, ozone, particulate matter, and SO2) to protect and improve the nation's air quality, which it reviews and revises
periodically. Following a NAAQS revision, states are required to develop an EPA-approved plan to protect air quality. These state
plans can require additional emission controls, improvements in control efficiency, or fuel changes which can result in increased
compliance and operational costs. NAAQS requirements can also adversely affect the siting of new electric generating facilities.
No areas within Alabama Power's service territory are currently designated nonattainment for any NAAQS. If areas are
designated as nonattainment in the future, increased compliance costs could result.
In 2011, the EPA finalized the Cross-State Air Pollution Rule (CSAPR) to address impacts of SO2 and NOX emissions from fossil
fuel-fired electric generating plants. CSAPR establishes emissions trading programs and budgets for certain states and allocates
emissions allowances for sources in those states. In 2016, the EPA published a final rule establishing more stringent ozone season
NOX emissions budgets in Alabama. Increases in either future fossil fuel-fired generation or the availability or cost of CSAPR
allowances could have a negative financial impact on results of operations for Alabama Power.
The EPA finalized regional haze regulations in 2005 and 2017. These regulations require states, tribal governments, and various
federal agencies to develop and implement plans to reduce pollutants that impair visibility and demonstrate reasonable progress
toward the goal of restoring natural visibility conditions in certain areas, including national parks and wilderness areas. States
must submit a revised state implementation plan (SIP) to the EPA demonstrating continued reasonable progress towards achieving
visibility improvement goals. The EPA approved the regional progress SIP for the State of Alabama.
16
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
Water Quality
In 2014, the EPA finalized requirements under Section 316(b) of the Clean Water Act (CWA) to regulate cooling water intake
structures (CWIS) to minimize their effects on fish and other aquatic life at existing power plants (e.g. coal, natural gas, oil, and
nuclear generating plants) and manufacturing facilities. The regulation requires plant-specific studies to determine applicable
CWIS changes to protect organisms that either get caught on the intake screens (impingement) or are drawn into the cooling
system (entrainment). Alabama Power is conducting these studies and currently anticipates applicable CWIS changes may include
fish-friendly CWIS screens with fish return systems and minor additions of monitoring equipment at certain plants. However, the
ultimate impact of this rule will depend on the outcome of these plant-specific studies, any additional protective measures
required to be incorporated into each plant's National Pollutant Discharge Elimination System (NPDES) permit based on site-
specific factors, and the outcome of any legal challenges.
In 2015, the EPA finalized the steam electric effluent limitations guidelines (ELG) rule (2015 ELG Rule) that set national
standards for wastewater discharges from new and existing steam electric generating units generating greater than 50 MWs. The
2015 ELG Rule prohibits effluent discharges of certain waste streams and imposes stringent limits on flue gas desulfurization
(scrubber) wastewater discharges. The revised technology-based limits and the CCR Rule require extensive changes to existing
ash and wastewater management systems or the installation and operation of new ash and wastewater management systems.
Compliance with the 2015 ELG Rule is expected to require capital expenditures and increased operational costs primarily for
Alabama Power's coal-fired electric generation. State environmental agencies will incorporate specific compliance applicability
dates in the NPDES permitting process for each ELG waste stream no later than December 31, 2023. The EPA is scheduled to
issue a new rulemaking by December 2019 that could revise the limitations and applicability dates of two of the waste streams
regulated in the 2015 ELG Rule. The impact of any changes to the 2015 ELG Rule will depend on the content of the new rule and
the outcome of any legal challenges. Alabama Power does not anticipate that the unavailability of any units as a result of the ELG
rule will have a material impact on Alabama Power's operations or financial condition.
In 2015, the EPA and the U.S. Army Corps of Engineers (Corps) jointly published a final rule that revised the regulatory
definition of waters of the United States (WOTUS) for all CWA programs. The rule significantly expanded the scope of federal
jurisdiction over waterbodies (such as rivers, streams, canals, and wastewater treatment ponds), which could impact new
generation projects and permitting and reporting requirements associated with the installation, expansion, and maintenance of
transmission and distribution projects. The EPA and the Corps are expected to publish a final rule in 2019 to replace the 2015
WOTUS definition. The impact of any changes to the 2015 WOTUS rule will depend on the content of this final rule and the
outcome of any legal challenges.
Coal Combustion Residuals
In 2015, the EPA finalized non-hazardous solid waste regulations for the disposal of CCR, including coal ash and gypsum, in
landfills and surface impoundments (ash ponds) at active generating power plants. In addition to the EPA's CCR Rule, the State of
Alabama has also finalized regulations regarding the handling of CCR that have been provided to the EPA for review. This state
CCR rule is generally consistent with the federal CCR Rule. The EPA's CCR Rule requires landfills and ash ponds to be evaluated
against a set of performance criteria and potentially closed if minimum criteria are not met. Closure of existing landfills and ash
ponds could require installation of equipment and infrastructure to manage CCR in accordance with the CCR Rule. Based on cost
estimates for closure in place and monitoring of ash ponds pursuant to the CCR Rule, Alabama Power recorded AROs for each
CCR unit in 2015. As further analysis was performed and closure details were developed, Alabama Power has continued to
periodically update these cost estimates, as discussed further below.
The EPA published certain amendments to the CCR Rule, which became effective August 29, 2018. These amendments extend
the date from April 2019 to October 31, 2020 to cease sending CCR and other waste streams to ash ponds that demonstrate
compliance with all except two of the specified performance criteria.
On August 21, 2018, the U.S. Court of Appeals for the District of Columbia Circuit issued a decision suggesting the EPA should
regulate previously-excluded inactive ash ponds located at retired generation facilities and questioning both the ability of unlined
ash ponds to continue operating no matter the performance criteria results and the classification of clay-lined landfills and ash
ponds. These developments could impact the expected timing of Alabama Power's landfill and ash pond closure activities, but the
extent of any impact will depend on the outcome of ongoing litigation, anticipated EPA rulemaking action to establish further
guidance, and the outcome of any legal challenges.
In June 2018, Alabama Power recorded an increase of approximately $1.2 billion to its AROs related to the CCR Rule. The
revised cost estimates were based on information from feasibility studies performed on ash ponds in use at plants operated by
Alabama Power. During the second quarter 2018, Alabama Power's management completed its analysis of these studies which
indicated that additional closure costs, primarily related to increases in estimated ash volume, water management requirements,
17
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
and design revisions, will be required to close these ash ponds under the planned closure-in-place methodology. As the level of
work becomes more defined in the next 12 months, it is likely that these cost estimates will change and the change could be
material.
Alabama Power expects to periodically update its ARO cost estimates. Absent continued recovery of ARO costs through regulated
rates, Alabama Power's results of operations, cash flows, and financial condition could be materially impacted. See FINANCIAL
CONDITION AND LIQUIDITY – "Capital Requirements and Contractual Obligations" herein and Note 6 to the financial
statements for additional information.
The ultimate outcome of these matters cannot be determined at this time.
Nuclear Decommissioning
In June 2018, Alabama Power completed an updated decommissioning cost site study for Plant Farley. The estimated cost of
decommissioning based on the study resulted in an increase in Alabama Power's ARO liability of approximately $300 million.
Amounts previously contributed to Alabama Power's external trust funds are currently projected to be adequate to meet the
updated decommissioning obligations. See Note 6 to the financial statements for additional information.
Global Climate Issues
On August 31, 2018, the EPA published a proposed rule known as the Affordable Clean Energy (ACE) Rule, which is intended to
replace a regulation enacted in 2015 known as the Clean Power Plan (CPP), that would limit CO2 emissions from existing fossil
fuel-fired electric generating units. The CPP has been stayed by the U.S. Supreme Court since 2016. The ACE Rule would require
states to develop GHG unit-specific emission rate standards based on heat-rate efficiency improvements for existing fossil fuel-
fired steam units. As proposed, combustion turbines, including natural gas combined cycles, are not affected sources. As of
January 1, 2019, Alabama Power has ownership interests in 20 fossil fuel-fired steam units to which the proposed ACE Rule is
applicable. The ultimate impact of this rule to Alabama Power is currently unknown and will depend on changes between the
proposal and the final rule, subsequent state plan developments and requirements, and any associated legal challenges.
On December 20, 2018, the EPA published a proposed review of the Standards of Performance for Greenhouse Gas Emissions
from New, Modified, and Reconstructed Stationary Sources: Electric Utility Generating Units final rule (2015 NSPS rule). The
EPA's final 2015 NSPS rule set standards of performance for new, modified, and reconstructed electric utility generating units
which included stationary combustion turbines and fossil-fired steam boilers. This proposal reduces the stringency of the 2015
NSPS rule by not basing the new and reconstructed fossil-fired steam boiler and IGCC standards on partial carbon capture and
sequestration. The impact of any changes to this rule will depend on the content of the final rule and the outcome of any legal
challenges.
The EPA's GHG reporting rule requires annual reporting of GHG emissions expressed in terms of metric tons of CO2 equivalent
emissions for a company's operational control of facilities. Based on ownership or financial control of facilities, Alabama Power's
2017 GHG emissions were approximately 37 million metric tons of CO2 equivalent. The preliminary estimate of Alabama Power's
2018 GHG emissions on the same basis is approximately 36 million metric tons of CO2 equivalent.
Through 2017, the Southern Company system has achieved an estimated GHG emission reduction of 36% since 2007. In April
2018, Southern Company established an intermediate goal of a 50% reduction in carbon emissions from 2007 levels by 2030 and
a long-term goal of low- to no-carbon operations by 2050. To achieve these goals, the Southern Company system expects to
continue growing its renewable energy portfolio, optimize technology advancements to modernize its transmission and
distribution systems, increase the use of natural gas for generation, complete ongoing construction projects, invest in energy
efficiency, and continue research and development efforts focused on technologies to lower GHG emissions. The Southern
Company system's ability to achieve these goals also will be dependent on many external factors, including supportive national
energy policies, low natural gas prices, and the development, deployment, and advancement of relevant energy technologies.
FERC Matters
Open Access Transmission Tariff
On May 10, 2018, AMEA and Cooperative Energy filed with the FERC a complaint against SCS and the traditional electric
operating companies (including Alabama Power) claiming that the current 11.25% base ROE used in calculating the annual
transmission revenue requirements of the traditional electric operating companies' (including Alabama Power's) open access
transmission tariff is unjust and unreasonable as measured by the applicable FERC standards. The complaint requested that the
base ROE be set no higher than 8.65% and that the FERC order refunds for the difference in revenue requirements that results
from applying a just and reasonable ROE established in this proceeding upon determining the current ROE is unjust and
18
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
unreasonable. On June 18, 2018, SCS and the traditional electric operating companies (including Alabama Power) filed their
response challenging the adequacy of the showing presented by the complainants and offering support for the current ROE. On
September 6, 2018, the FERC issued an order establishing a refund effective date of May 10, 2018 in the event a refund is due
and initiating an investigation and settlement procedures regarding the current base ROE. Through December 31, 2018, the
estimated maximum potential refund is not expected to be material to Alabama Power's results of operations or cash flows. The
ultimate outcome of this matter cannot be determined at this time.
Retail Regulatory Matters
Alabama Power's revenues from regulated retail operations are collected through various rate mechanisms subject to the oversight
of the Alabama PSC. Alabama Power currently recovers its costs from the regulated retail business primarily through Rate RSE,
Rate CNP, Rate ECR, and Rate NDR. In addition, the Alabama PSC issues accounting orders to address current events impacting
Alabama Power. See Note 2 to the financial statements under "Alabama Power" for additional information regarding Alabama
Power's rate mechanisms and accounting orders.
Rate RSE
The Alabama PSC has adopted Rate RSE that provides for periodic annual adjustments based upon Alabama Power's projected
weighted common equity return (WCER) compared to an allowable range. Rate RSE adjustments are based on forward-looking
information for the applicable upcoming calendar year. Rate RSE adjustments for any two-year period, when averaged together,
cannot exceed 4.0% and any annual adjustment is limited to 5.0%. When the projected WCER is under the allowed range, there is
an adjusting point of 5.98% and eligibility for a performance-based adder of seven basis points, or 0.07%, to the WCER adjusting
point if Alabama Power (i) has an "A" credit rating equivalent with at least one of the recognized rating agencies or (ii) is in the
top one-third of a designated customer value benchmark survey. If Alabama Power's actual retail return is above the allowed
WCER range, the excess will be refunded to customers unless otherwise directed by the Alabama PSC; however, there is no
provision for additional customer billings should the actual retail return fall below the WCER range. Prior to January 2019, retail
rates remained unchanged when the WCER range was between 5.75% and 6.21%.
On May 1, 2018, the Alabama PSC approved modifications to Rate RSE and other commitments designed to position Alabama
Power to address the growing pressure on its credit quality resulting from the Tax Reform Legislation, without increasing retail
rates under Rate RSE in the near term. Alabama Power plans to reduce growth in total debt by increasing equity, with
corresponding reductions in debt issuances, thereby de-leveraging its capital structure. Alabama Power's goal is to achieve an
equity ratio of approximately 55% by the end of 2025. At December 31, 2018, Alabama Power's equity ratio was approximately
47%.
The approved modifications to Rate RSE began for billings in January 2019. The modifications include reducing the top of the
allowed WCER range from 6.21% to 6.15% and modifications to the refund mechanism applicable to prior year actual results.
The modifications to the refund mechanism allow Alabama Power to retain a portion of the revenue that causes the actual WCER
for a given year to exceed the allowed range.
Generally, if Alabama Power's actual WCER is between 6.15% and 7.65%, customers will receive 25% of the amount between
6.15% and 6.65%, 40% of the amount between 6.65% and 7.15%, and 75% of the amount between 7.15% and 7.65%. Customers
will receive all amounts in excess of an actual WCER of 7.65%.
In conjunction with these modifications to Rate RSE, on May 8, 2018, Alabama Power consented to a moratorium on any upward
adjustments under Rate RSE for 2019 and 2020 and will also return $50 million to customers through bill credits in 2019.
On November 30, 2018, Alabama Power made its required annual Rate RSE submission to the Alabama PSC of projected data for
calendar year 2019. Projected earnings were within the specified range; therefore, retail rates under Rate RSE remain unchanged
for 2019.
At December 31, 2018, Alabama Power's retail return exceeded the allowed WCER range, which resulted in Alabama Power
establishing a regulatory liability of $109 million for Rate RSE refunds. In accordance with an Alabama PSC order issued on
February 5, 2019, Alabama Power will apply $75 million to reduce the Rate ECR under recovered balance and the remaining $34
million will be refunded to customers through bill credits in July through September 2019.
Rate CNP PPA
Alabama Power's retail rates, approved by the Alabama PSC, provide for adjustments under Rate CNP to recognize the placing of
new generating facilities into retail service. Alabama Power may also recover retail costs associated with certificated PPAs under
19
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
Rate CNP PPA. No adjustments to Rate CNP PPA occurred during the period 2016 through 2018 and no adjustment is expected in
2019.
In accordance with an accounting order issued in February 2017 by the Alabama PSC, Alabama Power reclassified $69 million of
the December 31, 2016 Rate CNP PPA under recovered balance to a separate regulatory asset. The amortization of the new
regulatory asset through Rate RSE will begin concurrently with the effective date of Alabama Power's next depreciation study,
which is expected to occur no later than 2022.
Rate CNP Compliance
Rate CNP Compliance allows for the recovery of Alabama Power's retail costs associated with laws, regulations, and other such
mandates directed at the utility industry involving the environment, security, reliability, safety, sustainability, or similar
considerations impacting Alabama Power's facilities or operations. Rate CNP Compliance is based on forward-looking
information and provides for the recovery of these costs pursuant to a factor that is calculated annually. Compliance costs to be
recovered include operations and maintenance expenses, depreciation, and a return on certain invested capital. Revenues for Rate
CNP Compliance, as recorded on the financial statements, are adjusted for differences in actual recoverable costs and amounts
billed in current regulated rates. Accordingly, changes in the billing factor will have no significant effect on Alabama Power's
revenues or net income, but will affect annual cash flow. Changes in Rate CNP Compliance-related operations and maintenance
expenses and depreciation generally will have no effect on net income.
In accordance with an accounting order issued in February 2017 by the Alabama PSC, Alabama Power reclassified $36 million of
its under recovered balance in Rate CNP Compliance to a separate regulatory asset. The amortization of the new regulatory asset
through Rate RSE will begin concurrently with the effective date of Alabama Power's next depreciation study, which is expected
to occur no later than 2022.
On November 30, 2018, Alabama Power submitted calculations associated with its cost of complying with environmental
mandates, as provided under Rate CNP Compliance. The filing reflected a projected unrecovered retail revenue requirement for
environmental compliance of approximately $205 million, which is being recovered in the billing months of January 2019
through December 2019.
Rate ECR
Alabama Power has established energy cost recovery rates under Alabama Power's Rate ECR as approved by the Alabama PSC.
Rates are based on an estimate of future energy costs and the current over or under recovered balance. Revenues recognized under
Rate ECR and recorded on the financial statements are adjusted for the difference in actual recoverable fuel costs and amounts
billed in current regulated rates. The difference in the recoverable fuel costs and amounts billed give rise to the over or under
recovered amounts recorded as regulatory assets or liabilities. Alabama Power, along with the Alabama PSC, continually monitors
the over or under recovered cost balance to determine whether an adjustment to billing rates is required. Changes in the Rate ECR
factor have no significant effect on Alabama Power's net income, but will impact operating cash flows. Currently, the Alabama
PSC may approve billing rates under Rate ECR of up to 5.910 cents per KWH.
In accordance with an accounting order issued in February 2017 by the Alabama PSC, Alabama Power reclassified $36 million of
its under recovered balance in Rate ECR to a separate regulatory asset. The amortization of the new regulatory asset through Rate
RSE will begin concurrently with the effective date of Alabama Power's next depreciation study, which is expected to occur no
later than 2022. Alabama Power's current depreciation study became effective January 1, 2017.
On May 1, 2018, the Alabama PSC approved an increase to Rate ECR from 2.015 cents per KWH to 2.353 cents per KWH
effective July 2018 through December 2018. On December 4, 2018, the Alabama PSC issued a consent order to leave this rate in
effect through December 31, 2019. This change is expected to increase collections by approximately $183 million in 2019. Absent
any further order from the Alabama PSC, in January 2020, the rates will return to the originally authorized 5.910 cents per KWH.
As discussed herein under "Rate RSE," in accordance with an Alabama PSC order issued on February 5, 2019, Alabama Power
will utilize $75 million of the 2018 Rate RSE refund liability to reduce the Rate ECR under recovered balance.
Tax Reform Accounting Order
On May 1, 2018, the Alabama PSC approved an accounting order that authorized Alabama Power to defer the benefits of federal
excess deferred income taxes associated with the Tax Reform Legislation for the year ended December 31, 2018 as a regulatory
liability and to use up to $30 million of such deferrals to offset under recovered amounts under Rate ECR. The estimated deferrals
for the year ended December 31, 2018 totaled approximately $63 million, subject to adjustment following the filing of the 2018
tax return, of which $30 million was used to offset the Rate ECR under recovered balance and $33 million is recorded in other

Alabama Power Company 2018 Annual Report
regulatory liabilities, deferred on the balance sheet to be used for the benefit of customers as determined by the Alabama PSC at a
future date. See Note 10 to the financial statements under "Current and Deferred Income Taxes" for additional information.
Software Accounting Order
On February 5, 2019, the Alabama PSC approved an accounting order that authorizes Alabama Power to establish a regulatory
asset for operations and maintenance costs associated with software implementation projects. The regulatory asset will be
amortized ratably over the life of the related software.
Plant Greene County
Alabama Power jointly owns Plant Greene County with an affiliate, Mississippi Power. See Note 5 to the financial statements
under "Joint Ownership Agreements" for additional information regarding the joint ownership agreement. On August 6, 2018,
Mississippi Power filed its proposed Reserve Margin Plan (RMP) with the Mississippi PSC, which proposes a four-year
acceleration of the retirement of Plant Greene County Units 1 and 2 to the third quarter 2021 and the third quarter 2022,
respectively. Mississippi Power's proposed Plant Greene County unit retirements would require the completion of proposed
transmission and system reliability improvements, as well as agreement by Alabama Power. Alabama Power will continue to
monitor the status of Mississippi Power's proposed RMP and associated regulatory process as well as the proposed transmission
and system reliability improvements. Alabama Power will review all the facts and circumstances and will evaluate all its
alternatives prior to reaching a final determination on the ongoing operations of Plant Greene County. The ultimate outcome of
this matter cannot be determined at this time.
Request for Proposals for Future Generation
On September 21, 2018, Alabama Power issued a request for proposals of between 100 MWs and 1,200 MWs of capacity
beginning no later than 2023. On November 9, 2018, bids were received and an evaluation of those bids is in progress. Any
purchases will depend upon the cost competitiveness of the respective offers as well as other options available to Alabama Power.
The ultimate outcome of this matter cannot be determined at this time.
Rate NDR
Based on an order from the Alabama PSC, Alabama Power maintains a reserve for operations and maintenance expenses to cover
the cost of damages from major storms to its transmission and distribution facilities. The order approves a separate monthly Rate
NDR charge to customers consisting of two components. The first component is intended to establish and maintain a reserve
balance for future storms and is an on-going part of customer billing. When the reserve balance falls below $50 million, a reserve
establishment charge will be activated (and the on-going reserve maintenance charge concurrently suspended) until the reserve
balance reaches $75 million. In December 2017, the reserve maintenance charge was suspended and the reserve establishment
charge was activated as a result of the NDR balance falling below $50 million. Alabama Power expects to collect approximately
$16 million annually until the reserve balance is restored to $75 million. The NDR balance at December 31, 2018 was $20 million
and is included in other regulatory liabilities, deferred on the balance sheet.
The second component of the Rate NDR charge is intended to allow recovery of any existing deferred storm-related operations
and maintenance costs and any future reserve deficits over a 24-month period. The Alabama PSC order gives Alabama Power
authority to record a deficit balance in the NDR when costs of storm damage exceed any established reserve balance. Absent
further Alabama PSC approval, the maximum total Rate NDR charge consisting of both components is $10 per month per non-
residential customer account and $5 per month per residential customer account. Alabama Power has the authority, based on an
order from the Alabama PSC, to accrue certain additional amounts as circumstances warrant.
As revenue from the Rate NDR charge is recognized, an equal amount of operations and maintenance expenses related to the
NDR will also be recognized. As a result, the Rate NDR charge will not have an effect on net income but will impact operating
cash flows.
Environmental Accounting Order
Based on an order from the Alabama PSC (Environmental Accounting Order), Alabama Power is allowed to establish a regulatory
asset to record the unrecovered investment costs, including the unrecovered plant asset balance and the unrecovered costs
associated with site removal and closure associated with future unit retirements caused by environmental regulations. The
regulatory asset is being amortized and recovered over the affected unit's remaining useful life, as established prior to the decision
regarding early retirement through Rate CNP Compliance. At December 31, 2018, this regulatory asset had a balance of $42
million. See "Environmental Matters – Environmental Laws and Regulations" herein for additional information regarding
environmental regulations.
21
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
Subsequent to December 31, 2018, Alabama Power determined that Plant Gorgas Units 8, 9, and 10 (approximately 1,000 MWs)
will be retired by April 15, 2019 due to the expected costs of compliance with federal and state environmental regulations. In
accordance with the Environmental Accounting Order, approximately $740 million of net investment costs will be transferred to a
regulatory asset at the retirement date and recovered over the affected units' remaining useful lives, as established prior to the
decision to retire.
Income Tax Matters
Federal Tax Reform Legislation
In December 2017, the Tax Reform Legislation was signed into law and became effective on January 1, 2018. The Tax Reform
Legislation, among other things, reduced the federal corporate income tax rate to 21%, retained normalization provisions for
public utility property and existing renewable energy incentives, and repealed the corporate alternative minimum tax. In addition,
under the Tax Reform Legislation, net operating losses (NOLs) generated after December 31, 2017 can no longer be carried back
to previous tax years but can be carried forward indefinitely, with utilization limited to 80% of taxable income of the subsequent
tax year. The projected reduction of Southern Company's consolidated income tax liability resulting from the tax rate reduction
also delays the expected utilization of existing tax credit carryforwards. See Note 10 to the financial statements for information on
Southern Company's joint consolidated income tax allocation agreement.
Following the enactment of the Tax Reform Legislation, the SEC staff issued Staff Accounting Bulletin 118 – "Income Tax
Accounting Implications of the Tax Cuts and Jobs Act" (SAB 118), which provided for a measurement period of up to one year
from the enactment date to complete accounting under GAAP for the tax effects of the legislation. Due to the complex and
comprehensive nature of the enacted tax law changes and their application under GAAP, Alabama Power considered all amounts
recorded in the financial statements as a result of the Tax Reform Legislation "provisional" as discussed in SAB 118 and subject
to revision prior to filing its 2017 tax return in the fourth quarter 2018. Alabama Power recognized tax expense of $3 million in
2017 as a result of the Tax Reform Legislation. In addition, in total, Alabama Power recorded a $281 million decrease in
regulatory assets and a $2.0 billion increase in regulatory liabilities as a result of the Tax Reform Legislation. As of December 31,
2018, Alabama Power considered the measurement of impacts from the Tax Reform Legislation on deferred income tax assets and
liabilities, primarily due to the impact of the reduction of the corporate income tax rate, to be complete.
However, the IRS continues to issue regulations that provide further interpretation and guidance on the law and each state's
adoption of the provisions contained in the Tax Reform Legislation remains uncertain. The regulatory treatment of certain impacts
of the Tax Reform Legislation is subject to the discretion of the FERC. The ultimate impact of this matter cannot be determined at
this time. See Note 2 to the financial statements under "Alabama Power – Rate RSE" for additional information regarding
modifications to Rate RSE to reflect the impacts of the Tax Reform Legislation. Also see FINANCIAL CONDITION AND
LIQUIDITY – "Credit Rating Risk" herein and Note 10 to the financial statements under "Current and Deferred Income Taxes"
for additional information.
Bonus Depreciation
Under the Tax Reform Legislation, projects with binding contracts prior to September 28, 2017 and placed in service after
September 27, 2017 remain eligible for bonus depreciation under the PATH Act. The PATH Act allowed for 50% bonus
depreciation for 2015 through 2017, 40% bonus depreciation for 2018, and 30% bonus depreciation for 2019 and certain long-
lived assets placed in service in 2020. Based on provisional estimates, bonus depreciation is expected to result in positive cash
flows of approximately $100 million for the 2018 tax year and approximately $30 million for the 2019 tax year. See Note 10 to
the financial statements under "Current and Deferred Income Taxes" for additional information. The ultimate outcome of this
matter cannot be determined at this time.
Other Matters
Alabama Power is involved in various other matters being litigated and regulatory matters that could affect future earnings. In
addition, Alabama Power is subject to certain claims and legal actions arising in the ordinary course of business. Alabama Power's
business activities are subject to extensive governmental regulation related to public health and the environment, such as laws and
regulations governing air, water, land, and protection of other natural resources. Litigation over environmental issues and claims
of various types, including property damage, personal injury, common law nuisance, and citizen enforcement of environmental
laws and regulations, has occurred throughout the U.S. This litigation has included claims for damages alleged to have been
caused by CO2 and other emissions, CCR, and alleged exposure to hazardous materials, and/or requests for injunctive relief in
connection with such matters.
22
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
The ultimate outcome of such pending or potential litigation or regulatory matters cannot be predicted at this time; however, for
current proceedings not specifically reported herein or in Notes 2 and 3 to the financial statements, management does not
anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on Alabama
Power's financial statements. See Notes 2 and 3 to the financial statements for a discussion of various other contingencies,
regulatory matters, and other matters being litigated which may affect future earnings potential.
ACCOUNTING POLICIES
Application of Critical Accounting Policies and Estimates
Alabama Power prepares its financial statements in accordance with GAAP. Significant accounting policies are described in Notes
1, 5, and 6 to the financial statements. In the application of these policies, certain estimates are made that may have a material
impact on Alabama Power's results of operations and related disclosures. Different assumptions and measurements could produce
estimates that are significantly different from those recorded in the financial statements. Senior management has reviewed and
discussed the following critical accounting policies and estimates with the Audit Committee of Southern Company's Board of
Directors.
Utility Regulation
Alabama Power is subject to retail regulation by the Alabama PSC and wholesale regulation by the FERC. As a result, Alabama
Power applies accounting standards which require the financial statements to reflect the effects of rate regulation. Through the
ratemaking process, the regulators may require the inclusion of costs or revenues in periods different than when they would be
recognized by a non-regulated company. This treatment may result in the deferral of expenses and the recording of related
regulatory assets based on anticipated future recovery through rates or the deferral of gains or creation of liabilities and the
recording of related regulatory liabilities. The application of the accounting standards has a further effect on Alabama Power's
financial statements as a result of the estimates of allowable costs used in the ratemaking process. These estimates may differ
from those actually incurred by Alabama Power; therefore, the accounting estimates inherent in specific costs such as
depreciation, AROs, and pension and other postretirement benefits have less of a direct impact on Alabama Power's results of
operations and financial condition than they would on a non-regulated company.
As reflected in Note 2 to the financial statements under "Alabama Power – Regulatory Assets and Liabilities," significant
regulatory assets and liabilities have been recorded. Management reviews the ultimate recoverability of these regulatory assets
and any requirement to refund these regulatory liabilities based on applicable regulatory guidelines and GAAP. However, adverse
legislative, judicial, or regulatory actions could materially impact the amounts of such regulatory assets and liabilities and could
adversely impact Alabama Power's financial statements.
Asset Retirement Obligations
AROs are computed as the fair value of the estimated costs for an asset's future retirement and are recorded in the period in which
the liability is incurred. The estimated costs are capitalized as part of the related long-lived asset and depreciated over the asset's
useful life. In the absence of quoted market prices, AROs are estimated using present value techniques in which estimates of
future cash outlays associated with the asset retirements are discounted using a credit-adjusted risk-free rate. Estimates of the
timing and amounts of future cash outlays are based on projections of when and how the assets will be retired and the cost of
future removal activities.
The liability for AROs primarily relates to the decommissioning of Alabama Power's nuclear facility, Plant Farley, and facilities
that are subject to the CCR Rule and the related state rule, principally ash ponds. In addition, Alabama Power has AROs related to
various landfill sites, underground storage tanks, asbestos removal related to ongoing repair and maintenance, disposal of
polychlorinated biphenyls in certain transformers, and disposal of sulfur hexafluoride gas in certain substation breakers.
Alabama Power also has identified retirement obligations related to certain transmission and distribution facilities, asbestos
containing material within long-term assets not subject to ongoing repair and maintenance activities, and certain wireless
communication towers. However, liabilities for the removal of these assets have not been recorded because the settlement timing
for the retirement obligations related to these assets is indeterminable and, therefore, the fair value of the retirement obligations
cannot be reasonably estimated. A liability for these retirement obligations will be recognized when sufficient information
becomes available to support a reasonable estimation of the retirement obligation.
The cost estimates for AROs related to the disposal of CCR are based on information using various assumptions related to closure
and post-closure costs, timing of future cash outlays, inflation and discount rates, and the potential methods for complying with
the CCR Rule requirements for closure in place. In June 2018, Alabama Power recorded increases of approximately $1.2 billion
23
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
to its AROs related to the CCR Rule and approximately $300 million to its AROs related to updated nuclear decommissioning
cost site studies. The revised CCR-related cost estimates as of June 30, 2018 were based on information from feasibility studies
performed on ash ponds in use at the plants Alabama Power operates. During the second quarter 2018, Alabama Power's
management completed its analysis of these studies which indicated that additional closure costs, primarily related to increases in
estimated ash volume, water management requirements, and design revisions, will be required to close these ash ponds under the
planned closure-in-place methodology. As the level of work becomes more defined in the next 12 months, it is likely that these
cost estimates will change and the change could be material. Alabama Power expects to periodically update its ARO cost
estimates. See FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Laws and Regulations – Coal
Combustion Residuals" herein and Note 6 to the financial statements for additional information.
Given the significant judgment involved in estimating AROs, Alabama Power considers the liabilities for AROs to be critical
accounting estimates.
Pension and Other Postretirement Benefits
Alabama Power's calculation of pension and other postretirement benefits expense is dependent on a number of assumptions.
These assumptions include discount rates, healthcare cost trend rates, expected long-term return on plan assets, mortality rates,
expected salary and wage increases, and other factors. Components of pension and other postretirement benefits expense include
interest and service cost on the pension and other postretirement benefit plans, expected return on plan assets, and amortization of
certain unrecognized costs and obligations. Actual results that differ from the assumptions utilized are accumulated and amortized
over future periods and, therefore, generally affect recognized expense and the recorded obligation in future periods. While
Alabama Power believes that the assumptions used are appropriate, differences in actual experience or significant changes in
assumptions would affect its pension and other postretirement benefit costs and obligations.
Key elements in determining Alabama Power's pension and other postretirement benefit expense are the expected long-term
return on plan assets and the discount rate used to measure the benefit plan obligations and the periodic benefit plan expense for
future periods. The expected long-term return on pension and other postretirement benefit plan assets is based on Southern
Company's investment strategy, historical experience, and expectations for long-term rates of return that consider external
actuarial advice. Southern Company determines the long-term return on plan assets by applying the long-term rate of expected
returns on various asset classes to Southern Company's target asset allocation. For purposes of determining Alabama Power's
liability related to the pension and other postretirement benefit plans, Southern Company discounts the future related cash flows
using a single-point discount rate developed from the weighted average of market-observed yields for high quality fixed income
securities with maturities that correspond to expected benefit payments.
A 25 basis point change in any significant assumption (discount rate, salary increases, or long-term rate of return on plan assets)
would result in a $9 million or less change in total annual benefit expense, a $99 million or less change in the projected obligation
for the pension plan, and an $11 million or less change in the projected obligation for other post retirement benefit plans.
Alabama Power recorded pension costs of $27 million, $9 million, and $11 million in 2018, 2017, and 2016, respectively.
Postretirement benefit costs for Alabama Power were $2 million, $3 million, and $4 million in 2018, 2017, and 2016, respectively.
Such amounts are dependent on several factors including trust earnings and changes to the plans. A portion of pension and other
postretirement benefit costs is capitalized based on construction-related labor charges. Pension and other postretirement benefit
costs are a component of the regulated rates and generally do not have a long-term effect on net income.
See Note 11 to the financial statements for additional information regarding pension and other postretirement benefits.
Contingent Obligations
Alabama Power is subject to a number of federal and state laws and regulations, as well as other factors and conditions that
subject it to environmental, litigation, and other risks. See FUTURE EARNINGS POTENTIAL herein and Notes 2 and 3 to the
financial statements for more information regarding certain of these contingencies. Alabama Power periodically evaluates its
exposure to such risks and records reserves for those matters where a non-tax-related loss is considered probable and reasonably
estimable. The adequacy of reserves can be significantly affected by external events or conditions that can be unpredictable; thus,
the ultimate outcome of such matters could materially affect Alabama Power's results of operations, cash flows, or financial
condition.
24
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
Recently Issued Accounting Standards
See Note 1 to the financial statements under "Recently Adopted Accounting Standards" for additional information.
In 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (ASU 2016-02). ASU 2016-02 requires lessees to recognize on
the balance sheet a lease liability and a right-of-use asset for all leases. ASU 2016-02 also changes the recognition, measurement,
and presentation of expense associated with leases and provides clarification regarding the identification of certain components of
contracts that would represent a lease. The accounting required by lessors is relatively unchanged. ASU 2016-02 is effective for
fiscal years beginning after December 15, 2018 and Alabama Power adopted the new standard effective January 1, 2019.
Alabama Power elected the transition methodology provided by ASU No. 2018-11, Leases (Topic 842): Targeted Improvements,
whereby the requirements of ASU 2016-02 are applied on a prospective basis as of the adoption date of January 1, 2019, without
restating prior periods. Alabama Power elected the package of practical expedients provided by ASU 2016-02 that allows prior
determinations of whether existing contracts are, or contain, leases and the classification of existing leases to continue without
reassessment. Additionally, Alabama Power applied the use-of-hindsight practical expedient in determining lease terms as of the
date of adoption and elected the practical expedient that allows existing land easements not previously accounted for as leases not
to be reassessed. Alabama Power also made accounting policy elections to account for short-term leases in all asset classes as off-
balance sheet leases and combined lease and non-lease components in the computations of lease obligations and right-of-use
assets for most asset classes.
Alabama Power completed the implementation of a new application to track and account for its leases and updated its internal
controls and accounting policies to support the accounting for leases under ASU 2016-02. Alabama Power completed its lease
inventory and determined its most significant leases involve PPAs. In the first quarter 2019, the adoption of ASU 2016-02 resulted
in recording lease liabilities and right-of-use assets on Alabama Power's balance sheet each totaling approximately $195 million,
with no impact on Alabama Power's statement of income.
FINANCIAL CONDITION AND LIQUIDITY
Overview
Alabama Power's financial condition remained stable at December 31, 2018. Alabama Power's cash requirements primarily
consist of funding ongoing operations, common stock dividends, capital expenditures, and debt maturities. Capital expenditures
and other investing activities include investments to meet projected long-term demand requirements, to maintain existing
generation facilities, to comply with environmental regulations including adding environmental modifications to certain existing
generating units and closures of ash ponds, to expand and improve transmission and distribution facilities, and for restoration
following major storms. Operating cash flows provide a substantial portion of Alabama Power's cash needs. For the three-year
period from 2019 through 2021, Alabama Power's projected common stock dividends, capital expenditures, and debt maturities
are expected to exceed operating cash flows. Alabama Power plans to finance future cash needs in excess of its operating cash
flows primarily through external securities issuances, borrowings from financial institutions, or equity contributions from
Southern Company. Alabama Power plans to use commercial paper to manage seasonal variations in operating cash flows and for
other working capital needs. Alabama Power intends to continue to monitor its access to short-term and long-term capital markets
as well as its bank credit arrangements to meet future capital and liquidity needs. See "Sources of Capital," "Financing Activities,"
and "Capital Requirements and Contractual Obligations" herein for additional information.
Alabama Power's investments in the qualified pension plan and the nuclear decommissioning trust funds decreased in value as of
December 31, 2018 as compared to December 31, 2017. No contributions to the qualified pension plan were made for the year
ended December 31, 2018 and no mandatory contributions to the qualified pension plan are anticipated during 2019. Alabama
Power's funding obligations for the nuclear decommissioning trust funds are based on the most recent site study completed in
2018, and the next study is expected to be conducted by 2023. See Notes 6 and 11 to the financial statements under "Nuclear
Decommissioning" and "Pension Plans," respectively, for additional information.
Net cash provided from operating activities totaled $1.9 billion for 2018, an increase of $44 million as compared to 2017. The
increase in cash provided from operating activities was primarily due to an increase in weather-related revenues, fuel cost
recovery, and income tax refunds received in 2018, partially offset by materials and supplies purchases, the timing of vendor
payments, and settlement of AROs. Net cash provided from operating activities totaled $1.8 billion for 2017, a decrease of $112
million as compared to 2017. The decrease in cash provided from operating activities was primarily due to the timing of income
tax payments in 2017 and the receipt of income tax refunds in 2016 as a result of bonus depreciation, partially offset by the
voluntary contribution to the qualified pension plan in 2016.
25
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
Net cash used for investing activities totaled $2.3 billion for 2018, $1.9 billion for 2017, and $1.4 billion for 2016. These
activities were primarily related to gross property additions for environmental, distribution, transmission, and steam generation
assets.
Net cash provided from financing activities totaled $177 million in 2018 primarily due to issuances of long-term debt and
additional capital contributions from Southern Company, partially offset by the payment of common stock dividends and a
maturity of long-term debt. Net cash provided from financing activities totaled $163 million in 2017 primarily due to issuances of
long-term debt and additional capital contributions from Southern Company, partially offset by the payment of common stock
dividends and maturities of long-term debt. Fluctuations in cash flow from financing activities vary from year to year based on
capital needs and the maturity or redemption of securities.
Significant balance sheet changes for 2018 included increases of $2.84 billion in property, plant, and equipment primarily due to
$1.35 billion in AROs and additions to nuclear, distribution, and transmission assets. Other changes include $522 million in
capital contributions from Southern Company and $295 million in long-term debt primarily due to a senior notes issuance. See
Notes 6 and 8 to the financial statements for additional information related to changes in Alabama Power's AROs and financing
activities, respectively.
Alabama Power's ratio of common equity to total capitalization plus short-term debt was 47.0% and 46.3% at December 31, 2018
and 2017, respectively. See Note 8 to the financial statements for additional information.
Sources of Capital
Alabama Power plans to obtain the funds to meet its future capital needs from sources similar to those used in the past, which
were primarily from operating cash flows, external security issuances, borrowings from financial institutions, and equity
contributions from Southern Company. However, the amount, type, and timing of any future financings, if needed, will depend
upon prevailing market conditions, regulatory approval, and other factors. Subsequent to December 31, 2018, Alabama Power
received a capital contribution totaling $1.225 billion from Southern Company.
Security issuances are subject to regulatory approval by the Alabama PSC. Additionally, with respect to the public offering of
securities, Alabama Power files registration statements with the SEC under the Securities Act of 1933, as amended. The amounts
of securities authorized by the Alabama PSC are continuously monitored and appropriate filings are made to ensure flexibility in
the capital markets.
Alabama Power obtains financing separately without credit support from any affiliate. See Note 8 to the financial statements
under "Bank Credit Arrangements" for additional information. The Southern Company system does not maintain a centralized
cash or money pool. Therefore, funds of Alabama Power are not commingled with funds of any other company in the Southern
Company system.
At December 31, 2018, Alabama Power's current liabilities exceeded current assets by $50 million. Alabama Power's current
liabilities sometimes exceed current assets because of long-term debt maturities and the periodic use of short-term debt as a
funding source, as well as significant seasonal fluctuations in cash needs.
At December 31, 2018, Alabama Power had approximately $313 million of cash and cash equivalents. Committed credit
arrangements with banks at December 31, 2018 were as follows:

See Note 8 to the financial statements under "Bank Credit Arrangements" for additional information.
Most of these bank credit arrangements, as well as Alabama Power's term loan arrangements, contain covenants that limit debt
levels and contain cross-acceleration provisions to other indebtedness (including guarantee obligations) of Alabama Power. Such
cross-acceleration provisions to other indebtedness would trigger an event of default if Alabama Power defaulted on indebtedness,
the payment of which was then accelerated. At December 31, 2018, Alabama Power was in compliance with all such covenants.
None of the bank credit arrangements contain material adverse change clauses at the time of borrowings.
Subject to applicable market conditions, Alabama Power expects to renew or replace its bank credit arrangements as needed prior
to expiration. In connection therewith, Alabama Power may extend the maturity dates and/or increase or decrease the lending
commitments thereunder.

MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
A portion of the unused credit with banks is allocated to provide liquidity support to Alabama Power's pollution control revenue
bonds and commercial paper programs. The amount of variable rate pollution control revenue bonds outstanding requiring
liquidity support was $854 million at December 31, 2018.
Alabama Power also has substantial cash flow from operating activities and access to the capital markets, including a commercial
paper program, to meet liquidity needs. Alabama Power may meet short-term cash needs through its commercial paper program.
Alabama Power may also meet short-term cash needs through a Southern Company subsidiary organized to issue and sell
commercial paper at the request and for the benefit of Alabama Power and the other traditional electric operating companies.
Proceeds from such issuances for the benefit of Alabama Power are loaned directly to Alabama Power. The obligations of each
traditional electric operating company under these arrangements are several and there is no cross-affiliate credit support.

Alabama Power believes that the need for working capital can be adequately met by utilizing commercial paper programs, lines of
credit, and operating cash flows.
Financing Activities
In June 2018, Alabama Power issued $500 million aggregate principal amount of Series 2018A 4.300% Senior Notes due July 15,
2048. The proceeds were used to repay outstanding commercial paper and for general corporate purposes, including Alabama
Power's continuous construction program.
In October 2018, Alabama Power purchased and held $120 million aggregate principal amount of The Industrial Development
Board of the City of Mobile, Alabama Pollution Control Revenue Bonds (Alabama Power Company Plant Barry Project), Series
2008. Alabama Power reoffered these bonds to the public in November 2018.
In November 2018, Alabama Power guaranteed a $100 million three-year bank term loan for SEGCO. See Note 9 to the financial
statements under "Guarantees" for additional information.
Subsequent to December 31, 2018, Alabama Power repaid at maturity $200 million aggregate principal amount of Series Z
5.125% Senior Notes due February 15, 2019.
In addition to any financings that may be necessary to meet capital requirements and contractual obligations, Alabama Power
plans to continue, when economically feasible, a program to retire higher-cost securities and replace these obligations with lower-
cost capital if market conditions permit.
Credit Rating Risk
At December 31, 2018, Alabama Power did not have any credit arrangements that would require material changes in payment
schedules or terminations as a result of a credit rating downgrade.
27
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
There are certain contracts that could require collateral, but not accelerated payment, in the event of a credit rating change to BBB
and/or Baa2 or below. These contracts are primarily for physical electricity purchases, fuel purchases, fuel transportation and
storage, energy price risk management, and transmission.
The maximum potential collateral requirements under these contracts at December 31, 2018 were as follows:

Included in these amounts are certain agreements that could require collateral in the event that either Alabama Power or Georgia
Power (an affiliate of Alabama Power) has a credit rating change to below investment grade. Generally, collateral may be
provided by a Southern Company guaranty, letter of credit, or cash. Additionally, a credit rating downgrade could impact the
ability of Alabama Power to access capital markets and would be likely to impact the cost at which it does so.
On September 28, 2018, Fitch assigned a negative rating outlook to the ratings of Southern Company and certain of its
subsidiaries (including Alabama Power).
Also on September 28, 2018, Moody's revised its rating outlook for Alabama Power from negative to stable.
As a result of the Tax Reform Legislation, certain financial metrics, such as the funds from operations to debt percentage, used by
the credit rating agencies to assess Southern Company and its subsidiaries, including Alabama Power, may be negatively
impacted. The modifications to Rate RSE and other commitments approved by the Alabama PSC are expected to help mitigate
these potential adverse impacts to certain credit metrics and will help Alabama Power meet its goal of achieving an equity ratio of
approximately 55% by the end of 2025. See Note 2 to the financial statements under "Alabama Power – Rate RSE" for additional
information.
Market Price Risk
Due to cost-based rate regulation and other various cost recovery mechanisms, Alabama Power continues to have limited
exposure to market volatility in interest rates, commodity fuel prices, and prices of electricity. To manage the volatility
attributable to these exposures, Alabama Power nets the exposures, where possible, to take advantage of natural offsets and enters
into various derivative transactions for the remaining exposures pursuant to Alabama Power's policies in areas such as
counterparty exposure and risk management practices. Alabama Power's policy is that derivatives are to be used primarily for
hedging purposes and mandates strict adherence to all applicable risk management policies. Derivative positions are monitored
using techniques including, but not limited to, market valuation, value at risk, stress testing, and sensitivity analysis.
To mitigate future exposure to changes in interest rates, Alabama Power may enter into derivatives designated as hedges. The
weighted average interest rate on $1.1 billion of long-term variable interest rate exposure at December 31, 2018 was 2.5%. If
Alabama Power sustained a 100 basis point change in interest rates for all long-term variable interest rate exposure, the change
would affect annualized interest expense by approximately $11 million at December 31, 2018. See Note 1 to the financial
statements under "Financial Instruments" and Note 14 to the financial statements for additional information.
To mitigate residual risks relative to movements in electricity prices, Alabama Power enters into physical fixed-price contracts for
the purchase and sale of electricity through the wholesale electricity market and financial hedge contracts for natural gas
purchases. Alabama Power continues to manage a retail fuel-hedging program implemented per the guidelines of the Alabama
PSC. Alabama Power had no material change in market risk exposure for the year ended December 31, 2018 when compared to
the year ended December 31, 2017.
In addition, Rate ECR allows the recovery of specific costs associated with the sales of natural gas that become necessary due to
operating considerations at Alabama Power's electric generating facilities. Rate ECR also allows recovery of the cost of financial
instruments used for hedging market price risk up to 75% of the budgeted annual amount of natural gas purchases. Alabama
Power may not engage in natural gas hedging activities that extend beyond a rolling 42-month window. Also, the premiums paid
for natural gas financial options may not exceed 5% of Alabama Power's natural gas budget for that year.
28
MANAGEMENT'S DISCUSSION AND ANALYSIS (continued)
Alabama Power Company 2018 Annual Report
The changes in fair value of energy-related derivative contracts are substantially attributable to both the volume and the price of
natural gas. For the years ended December 31, the changes in fair value of energy-related derivative contracts, the majority of
which are composed of regulatory hedges, were as follows:
Contracts outstanding at the beginning of the period, assets (liabilities), net
Contracts realized or settled
Current period changes(*)
Contracts outstanding at the end of the period, assets (liabilities), net

The weighted average swap contract cost above market prices was approximately $0.08 per mmBtu at December 31, 2018 and
December 31, 2017. The change in option fair value is primarily attributable to the volatility of the market and the underlying
change in the natural gas price. Substantially all of the natural gas hedge gains and losses are recovered through Alabama
Power's retail energy cost recovery clause.
At December 31, 2018 and 2017, substantially all of Alabama Power's energy-related derivative contracts were designated as
regulatory hedges and were related to Alabama Power's fuel-hedging program. Therefore, gains and losses are initially recorded
as regulatory liabilities and assets, respectively, and then are included in fuel expense as they are recovered through the energy
cost recovery clause. Certain other gains and losses on energy-related derivatives, designated as cash flow hedges, are initially
deferred in OCI before being recognized in income in the same period as the hedged transaction. Gains and losses on energy-
related derivative contracts that are not designated or fail to qualify as hedges are recognized in the statements of income as
incurred and were not material for any year presented.
Alabama Power uses over-the-counter contracts that are not exchange traded but are fair valued using prices which are market
observable, and thus fall into Level 2 of the fair value hierarchy. See Note 13 to the financial statements for further discussion of
fair value measurements. The maturities of the energy-related derivative contracts, which are primarily Level 2 of the fair value
hierarchy, at December 31, 2018 were as follows:

Alabama Power is exposed to market price risk in the event of nonperformance by counterparties to energy-related and interest
rate derivative contracts. Alabama Power only enters into agreements and material transactions with counterparties that have
29

Alabama Power Company 2018 Annual Report
investment grade credit ratings by Moody's and S&P, or with counterparties who have posted collateral to cover potential credit
exposure. Therefore, Alabama Power does not anticipate market risk exposure from nonperformance by the counterparties. For
additional information, see Note 1 to the financial statements under "Financial Instruments" and Note 14 to the financial
statements.
Capital Requirements and Contractual Obligations
The construction program of Alabama Power is currently estimated to total $1.8 billion for 2019, $1.6 billion for 2020, $1.6
billion for 2021, $1.4 billion for 2022, and $1.5 billion for 2023. The construction program includes capital expenditures related
to contractual purchase commitments for nuclear fuel and capital expenditures covered under LTSAs. Estimated capital
expenditures to comply with environmental laws and regulations included in these amounts are $226 million for 2019, $68
million for 2020, $118 million for 2021, $112 million for 2022, and $111 million for 2023. These estimated expenditures do not
include any potential compliance costs associated with pending regulation of CO2 emissions from fossil-fuel-fired electric
generating units. See FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Laws and Regulations"
and "– Global Climate Issues" herein for additional information.
Alabama Power also anticipates costs associated with closure-in-place and monitoring of ash ponds in accordance with the CCR
Rule, which are reflected in Alabama Power's ARO liabilities. These costs, which are expected to change and could change
materially as underlying assumptions are refined and the cost, method, and timing of compliance activities continue to be
evaluated, are currently estimated to be $232 million for 2019, $238 million for 2020, $246 million for 2021, $252 million for
2022, and $258 million for 2023. See FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Laws and
Regulations – Coal Combustion Residuals" herein and Note 6 to the financial statements for additional information. Costs
associated with the CCR Rule are expected to be recovered through Rate CNP Compliance.
The construction program is subject to periodic review and revision, and actual construction costs may vary from these estimates
because of numerous factors. These factors include: changes in business conditions; changes in load projections; changes in
environmental laws and regulations; the outcome of any legal challenges to environmental rules; changes in generating plants,
including unit retirements and replacements and adding or changing fuel sources at existing generating units, to meet regulatory
requirements; changes in the expected environmental compliance program; changes in FERC rules and regulations; Alabama PSC
approvals; changes in legislation; the cost and efficiency of construction labor, equipment, and materials; project scope and design
changes; storm impacts; and the cost of capital. In addition, there can be no assurance that costs related to capital expenditures
will be fully recovered.
As a result of NRC requirements, Alabama Power has external trust funds for nuclear decommissioning costs; however, Alabama
Power currently has no additional funding requirements. For additional information, see Note 6 to the financial statements under
"Nuclear Decommissioning."
In addition, as discussed in Note 11 to the financial statements, Alabama Power provides postretirement benefits to substantially
all employees and funds trusts to the extent required by the Alabama PSC and the FERC.
Funding requirements related to obligations associated with scheduled maturities of long-term debt, as well as the related interest,
derivative obligations, pension and other postretirement benefit plans, preferred stock dividends, leases, other purchase
commitments, and ARO settlements are detailed in the contractual obligations table that follows. See Notes 1, 6, 8, 9, 11, and 14
to the financial statements for additional information.

(a) All amounts are reflected based on final maturity dates. Alabama Power plans to continue, when economically feasible, to retire higher-cost securities and
replace these obligations with lower-cost capital if market conditions permit. Variable rate interest obligations are estimated based on rates at December 31,
2018, as reflected in the statements of capitalization. Fixed rates include, where applicable, the effects of interest rate derivatives employed to manage interest
rate risk. Long-term debt excludes capital lease amounts (shown separately).
(b) Preferred stock does not mature; therefore, amounts are provided for the next five years only.
(c) Includes derivative liabilities related to cash flow hedges of forecasted debt, as well as energy-related derivatives. For additional information, see Notes 1 and
14 to the financial statements.
(d) Excludes PPAs that are accounted for as leases and are included in purchased power.
(e) Alabama Power provides estimated capital expenditures for a five-year period, including capital expenditures associated with environmental regulations.
These amounts exclude contractual purchase commitments for nuclear fuel, capital expenditures covered under LTSAs, and estimated capital expenditures for
AROs, which are reflected in "Fuel," "Other," and "ARO settlements," respectively. At December 31, 2018, purchase commitments were outstanding in
connection with the construction program. See FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Laws and Regulations"
herein for additional information.
(f) Includes commitments to purchase coal, nuclear fuel, and natural gas, as well as the related transportation and storage. In most cases, these contracts contain
provisions for price escalation, minimum purchase levels, and other financial commitments. Natural gas purchase commitments are based on various indices
at the time of delivery. Amounts reflected for natural gas purchase commitments have been estimated based on the NYMEX future prices at December 31,
2018.
(g) Estimated minimum long-term obligations for various long-term commitments for the purchase of capacity and energy.
(h) Includes LTSAs and contracts for the procurement of limestone. LTSAs include price escalation based on inflation indices.
(i) Represents estimated costs for a five-year period associated with closing and monitoring ash ponds in accordance with the CCR Rule and the related state
rule, which are reflected in Alabama Power's ARO liabilities. Material expenditures in future years for ARO settlements also will be required for ash ponds,
nuclear decommissioning, and other liabilities reflected in Alabama Power's AROs. See FUTURE EARNINGS POTENTIAL – "Environmental Matters –
Environmental Laws and Regulations – Coal Combustion Residuals" herein and Note 6 to the financial statements for additional information.
(j) Alabama Power forecasts contributions to the pension and other postretirement benefit plans over a three-year period. Alabama Power anticipates no
mandatory contributions to the qualified pension plan during the next three years. Amounts presented represent estimated benefit payments for the
nonqualified pension plans, estimated non-trust benefit payments for the other postretirement benefit plans, and estimated contributions to the other
postretirement benefit plan trusts, all of which will be made from Alabama Power's corporate assets. See Note 11 to the financial statements for additional
information related to the pension and other postretirement benefit plans, including estimated benefit payments. Certain benefit payments will be made
through the related benefit plans. Other benefit payments will be made from Alabama Power's corporate assets.

NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
General
Southern Company is the parent company of the traditional electric operating companies, Southern Power, Southern Company
Gas (as of July 1, 2016), SCS, Southern Linc, Southern Holdings, Southern Nuclear, PowerSecure (as of May 9, 2016), and other
direct and indirect subsidiaries. The traditional electric operating companies – Alabama Power, Georgia Power, Gulf Power
(through December 31, 2018), and Mississippi Power – are vertically integrated utilities providing electric service in four
Southeastern states. On January 1, 2019, Southern Company completed the sale of Gulf Power to NextEra Energy. Southern
Power develops, constructs, acquires, owns, and manages power generation assets, including renewable energy projects, and sells
electricity at market-based rates in the wholesale market. On May 22, 2018, Southern Power sold a noncontrolling 33% equity
interest in SP Solar, a limited partnership indirectly owning substantially all of Southern Power's solar facilities, and, on
December 11, 2018, Southern Power sold a noncontrolling tax equity interest in SP Wind, a holding company owning a portfolio
of eight operating wind facilities. On November 5, 2018, Southern Power entered into an agreement to sell all of its equity
interests in Plant Mankato (including the 385-MW expansion currently under construction). On December 4, 2018, Southern
Power sold all of its equity interests in Plant Oleander and Plant Stanton Unit A (together, the Florida Plants) to NextEra Energy.
Southern Company Gas distributes natural gas through natural gas distribution utilities and is involved in several other
complementary businesses including gas pipeline investments, wholesale gas services, and gas marketing services. In July 2018,
Southern Company Gas completed sales of three of its natural gas distribution utilities (Elizabethtown Gas (New Jersey), Florida
City Gas, and Elkton Gas (Maryland)). The remaining natural gas distribution utilities include Nicor Gas (Illinois), Atlanta Gas
Light (Georgia), Virginia Natural Gas, and Chattanooga Gas (Tennessee). In June 2018, Southern Company Gas also completed
the sale of Pivotal Home Solutions, which provided home equipment protection products and services. SCS, the system service
company, provides, at cost, specialized services to Southern Company and its subsidiary companies. Southern Linc provides
digital wireless communications for use by Southern Company and its subsidiary companies and also markets these services to
the public and provides fiber optics services within the Southeast. Southern Holdings is an intermediate holding company
subsidiary, primarily for Southern Company's investments in leveraged leases and for other electric services. Southern Nuclear
operates and provides services to the Southern Company system's nuclear power plants, including Alabama Power's Plant Farley
and Georgia Power's Plant Hatch and Plant Vogtle Units 1 and 2, and is currently managing construction of and developing Plant
Vogtle Units 3 and 4, which are co-owned by Georgia Power. PowerSecure is a provider of energy solutions, including distributed
energy infrastructure, energy efficiency products and services, and utility infrastructure services, to customers. See Note 15 for
additional information regarding disposition activities.
The registrants' financial statements reflect investments in subsidiaries on a consolidated basis. Intercompany transactions have
been eliminated in consolidation. The equity method is used for investments in entities in which a registrant has significant
influence but does not control and for VIEs where a registrant has an equity investment but is not the primary beneficiary.
Southern Power has consolidated renewable generation projects that are partially funded by tax equity investors. The related
contractual provisions represent profit-sharing arrangements because the allocations of cash distributions and tax benefits are not
based on fixed ownership percentages. Therefore, the noncontrolling interest is accounted for under a balance sheet approach
utilizing the HLBV method. The HLBV method calculates each partner's share of income based on the change in net equity the
partner can legally claim in a HLBV at the end of the period compared to the beginning of the period. See Note 7 for additional
information.
The traditional electric operating companies, Southern Power, certain subsidiaries of Southern Company Gas, and certain other
subsidiaries are subject to regulation by the FERC, and the traditional electric operating companies and natural gas distribution
utilities are also subject to regulation by their respective state PSCs or other applicable state regulatory agencies. As such, the
respective financial statements of the registrants reflect the effects of rate regulation in accordance with GAAP and comply with
the accounting policies and practices prescribed by relevant state PSCs or other applicable state regulatory agencies.
The preparation of financial statements in conformity with GAAP requires the use of estimates, and the actual results may differ
from those estimates. Certain prior years' data presented in the financial statements have been reclassified to conform to the
current year presentation. These reclassifications had no impact on the registrants' results of operations, financial position, or cash
flows. In addition, Southern Company Gas has recast its reportable segments. See Note 16 under "Southern Company Gas" for
additional information.
At December 31, 2018, Southern Company and Southern Power each had assets and liabilities held for sale on their balance
sheets. Unless otherwise noted, the disclosures herein related to specific asset and liability balances at December 31, 2018 exclude
assets and liabilities held for sale. See Note 15 under "Assets Held for Sale" for additional information including Southern
Company's and Southern Power's major classes of assets and liabilities classified as held for sale.
41
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Southern Company Gas
Pursuant to the Merger, Southern Company pushed down the application of the acquisition method of accounting to the financial
statements of Southern Company Gas such that the assets and liabilities are recorded at their respective fair values, and goodwill
was established for the excess of the purchase price over the fair value of net identifiable assets. Accordingly, the financial
statements of Southern Company Gas for periods before and after July 1, 2016 (acquisition date) reflect different bases of
accounting, and the financial positions and results of operations of those periods are not comparable. Throughout Southern
Company Gas' financial statements and the combined notes to the financial statements, periods prior to July 1, 2016 are identified
as "predecessor," while periods after the acquisition date are identified as "successor."
Certain predecessor period data presented in Southern Company Gas' financial statements has been modified or reclassified to
conform to the presentation used by Southern Company. Changes to Southern Company Gas' statements of income include
classifying operating revenues as natural gas revenues and other revenues, as well as classifying cost of goods sold as cost of
natural gas and cost of other sales and presenting interest expense and AFUDC on a gross basis. Changes to Southern Company
Gas' statements of cash flows include revised financial statement line item descriptions to align with the new balance sheet
descriptions and expanded line items within each category of cash flow activity.
Recently Adopted Accounting Standards
Revenue
In 2014, the FASB issued ASC 606, Revenue from Contracts with Customers (ASC 606), replacing the existing accounting
standard and industry-specific guidance for revenue recognition with a five-step model for recognizing and measuring revenue
from contracts with customers. The underlying principle of the standard is to recognize revenue to depict the transfer of goods or
services to customers at the amount expected to be collected. ASC 606 became effective on January 1, 2018 and the registrants
adopted it using the modified retrospective method applied to open contracts and only to the version of contracts in effect as of
January 1, 2018. In accordance with the modified retrospective method, the registrants' previously issued financial statements
have not been restated to comply with ASC 606 and the registrants did not have a cumulative-effect adjustment to retained
earnings. The adoption of ASC 606 had no significant impact on the timing of revenue recognition compared to previously
reported results; however, it requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenue and
the related cash flows arising from contracts with customers, which are included herein and in Note 4.
ASC 606 provided additional clarity on financial statement presentation that resulted in reclassifications into other revenues and
other operations and maintenance from other income/(expense), net at Alabama Power and Georgia Power primarily related to
certain unregulated sales of products and services. In addition, contract assets related to certain fixed retail revenues at Georgia
Power and Southern Company's unregulated distributed generation business have been reclassified from unbilled revenue in
accordance with the guidance in ASC 606. These reclassifications did not affect the timing or amount of revenues recognized or
cash flows. ASC 606 also provided additional guidance on revenue recognized over time, resulting in a change in the timing of
revenue recognized from guaranteed and fixed billing arrangements at Southern Company Gas.

NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Other
In 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18). ASU
2016-18 eliminates the need to reflect transfers between cash and restricted cash in operating, investing, and financing activities
in the statements of cash flows. In addition, the net change in cash and cash equivalents during the period includes amounts
generally described as restricted cash or restricted cash equivalents. The registrants adopted ASU 2016-18 retrospectively
effective January 1, 2018. Southern Company, Southern Power, and Southern Company Gas have restated prior periods in the
statements of cash flows by immaterial amounts. The change in restricted cash in the statements of cash flows was previously
disclosed in operating activities for Southern Company and Southern Company Gas and in investing activities for Southern
Company and Southern Power. See "Restricted Cash" herein for additional information.
In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for
Goodwill Impairment (ASU 2017-04). ASU 2017-04 removes the requirement to compare the implied fair value of goodwill with
the carrying amount as part of Step 2 of the goodwill impairment test. Under the new standard, the goodwill impairment loss will
be measured as the excess of a reporting unit's carrying amount over its fair value, not exceeding the total amount of goodwill
allocated to that reporting unit, which may increase the frequency of goodwill impairment charges if a future goodwill impairment
test does not pass the Step 1 evaluation. ASU 2017-04 is effective prospectively for periods beginning on or after December 15,
2019, with early adoption permitted. The registrants adopted ASU 2017-04 effective January 1, 2018 with no impact on their
respective financial statements.
In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation
of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (ASU 2017-07). ASU 2017-07 requires that an
employer report the service cost component in the same line item or items as other compensation costs and requires the other
components of net periodic pension and postretirement benefit costs to be separately presented in the statements of income
outside of income from operations. Additionally, only the service cost component is eligible for capitalization, when applicable.
The registrants adopted ASU 2017-07 effective January 1, 2018 with no material impact on their respective financial statements.
ASU 2017-07 has been applied retrospectively, with the service cost component of net periodic benefit costs included in
operations and maintenance expenses and all other components of net periodic benefit costs included in other income (expense),
net in the statements of income for all periods presented for Southern Company, the traditional electric operating companies, and
Southern Company Gas. The impacted registrants used the practical expedient provided by ASU 2017-07, which permits an
employer to use the amounts disclosed in its retirement benefits note for prior comparative periods as the estimation basis for
applying the retrospective presentation requirements to those periods. The amounts of the other components of net periodic
benefit costs reclassified for the prior periods are presented in Note 11. The presentation changes resulted in a decrease in
operating income and an increase in other income for the years ended December 31, 2017 and 2016 for each of the impacted
registrants. Since Southern Power did not participate in the qualified pension and postretirement benefit plans until December
2017, no retrospective presentation of Southern Power's net periodic benefit costs is required. The requirement to limit
capitalization to the service cost component of net periodic benefit costs has been applied on a prospective basis from the date of
adoption for all registrants.
In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting
for Hedging Activities (ASU 2017-12). ASU 2017-12 makes more financial and non-financial hedging strategies eligible for
hedge accounting, amends the related presentation and disclosure requirements, and simplifies hedge effectiveness assessment
requirements. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The
registrants adopted ASU 2017-12 effective January 1, 2018 with no material impact on their respective financial statements. See
Note 14 for disclosures required by ASU 2017-12.
On February 14, 2018, the FASB issued ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220):
Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASU 2018-02) to address the application
of ASC 740, Income Taxes (ASC 740) to certain provisions of the Tax Reform Legislation. ASU 2018-02 specifically addresses
the ASC 740 requirement that the effect of a change in tax laws or rates on deferred tax assets and liabilities be included in
income from continuing operations, even when the tax effects were initially recognized directly in OCI at the previous rate, which
strands the income tax rate differential in accumulated OCI. The amendments in ASU 2018-02 allow a reclassification from
accumulated OCI to retained earnings for stranded tax effects resulting from the Tax Reform Legislation. The registrants adopted
ASU 2018-02 effective January 1, 2018 with no material impact on their respective financial statements.
On August 28, 2018, the FASB issued ASU No. 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans – General
(Topic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans (ASU 2018-14).
ASU 2018-14 amends ASC 715 to add, remove, and clarify disclosure requirements related to defined benefit pension and other

based on the Southern Company Open Access Transmission Tariff as filed with the FERC.
The traditional electric operating companies and Southern Power may jointly enter into various types of wholesale energy, natural
gas, and certain other contracts, either directly or through SCS as agent. Each participating company may be jointly and severally
liable for the obligations incurred under these agreements. See Note 9 under "Fuel and Power Purchase Agreements" for
additional information. Southern Power and the traditional electric operating companies generally settle amounts related to the
above transactions on a monthly basis in the month following the performance of such services or the purchase or sale of
electricity. See "Revenues – Southern Power" herein for additional information.
The traditional electric operating companies, Southern Power, and Southern Company Gas provide incidental services to and
receive such services from other Southern Company subsidiaries which are generally minor in duration and amount. Except as
described herein, the traditional electric operating companies, Southern Power, and Southern Company Gas neither provided nor
received any material services to or from affiliates in 2018, 2017, or 2016.
Regulatory Assets and Liabilities
The traditional electric operating companies and natural gas distribution utilities are subject to accounting requirements for the
effects of rate regulation. Regulatory assets represent probable future revenues associated with certain costs that are expected to
be recovered from customers through the ratemaking process. Regulatory liabilities represent probable future reductions in
revenues associated with amounts that are expected to be credited to customers through the ratemaking process.
In the event that a portion of a traditional electric operating company's or a natural gas distribution utility's operations is no longer
subject to applicable accounting rules for rate regulation, such company would be required to write off to income or reclassify to
AOCI related regulatory assets and liabilities that are not specifically recoverable through regulated rates. In addition, the
traditional electric operating company or natural gas distribution utility would be required to determine if any impairment to other
assets, including plant, exists and write down the assets, if impaired, to their fair values. All regulatory assets and liabilities are to
be reflected in rates. See Note 2 for additional information including details of regulatory assets and liabilities reflected in the
balance sheets for Southern Company, the traditional electric operating companies, and Southern Company Gas.

NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Revenues
The registrants generate revenues from a variety of sources which are accounted for under various revenue accounting guidance,
including ASC 606, lease, derivative, and regulatory accounting. Other than the timing of recognition of guaranteed and fixed
billing arrangements at Southern Company Gas, the adoption of ASC 606 had no impact on the timing or amount of revenue
recognized under previous guidance. See "Recently Adopted Accounting Standards – Revenue" herein and Note 4 for information
regarding the registrants' adoption of ASC 606 and related disclosures.
Traditional Electric Operating Companies
The majority of the revenues of the traditional electric operating companies are generated from contracts with retail electric
customers. Retail revenues recognized under ASC 606 are consistent with prior revenue recognition policies. These revenues,
generated from the integrated service to deliver electricity when and if called upon by the customer, are recognized as a single
performance obligation satisfied over time, at a tariff rate, and as electricity is delivered to the customer during the month.
Unbilled revenues related to retail sales are accrued at the end of each fiscal period. Retail rates may include provisions to adjust
billings for fluctuations in fuel costs, fuel hedging, the energy component of purchased power costs, and certain other costs.
Revenues are adjusted for differences between these actual costs and amounts billed in current regulated rates. Under or over
recovered regulatory clause revenues are recorded in the balance sheets and are recovered from or returned to customers,
respectively, through adjustments to the billing factors. See Note 2 for additional information regarding regulatory matters of the
traditional electric operating companies.
Wholesale capacity revenues from PPAs are recognized either on a levelized basis over the appropriate contract period or the
amount billable under the contract terms. Energy and other revenues are generally recognized as services are provided. The
accounting for these revenues under ASC 606 is consistent with prior revenue recognition policies. The contracts for capacity and
energy in a wholesale PPA have multiple performance obligations where the contract's total transaction price is allocated to each
performance obligation based on the standalone selling price. The standalone selling price is primarily determined by the price
charged to customers for the specific goods or services transferred with the performance obligations. Generally, the traditional
electric operating companies recognize revenue as the performance obligations are satisfied over time as electricity is delivered to
the customer or as generation capacity is available to the customer.
For both retail and wholesale revenues, the traditional electric operating companies generally have a right to consideration in an
amount that corresponds directly with the value to the customer of the entity's performance completed to date and may recognize
revenue in the amount to which the entity has a right to invoice and has elected to recognize revenue for its sales of electricity and
capacity using the invoice practical expedient. In addition, payment for goods and services rendered is typically due in the
subsequent month following satisfaction of the registrants' performance obligation.
Southern Power
Southern Power sells capacity and energy at rates specified under contractual terms in long-term PPAs. These PPAs are accounted
for as operating leases, non-derivatives, or normal sale derivatives. Capacity revenues from PPAs classified as operating leases are
recognized on a straight-line basis over the term of the agreement. Energy revenues are recognized in the period the energy is
delivered.
Southern Power's non-lease contracts commonly include capacity and energy which are considered separate performance
obligations. In these contracts, the total transaction price is allocated to each performance obligation based on the standalone
selling price. The standalone selling price is primarily determined by the price charged to customers for the specific goods or
services transferred with the performance obligations. Generally, Southern Power recognizes revenue as the performance
obligations are satisfied over time, as electricity is delivered to the customer or as generation capacity is made available to the
customer. The timing of revenue recognition was not affected by the adoption of ASC 606.
Southern Power generally has a right to consideration in an amount that corresponds directly with the value to the customer of the
entity's performance completed to date and may recognize revenue in the amount to which the entity has a right to invoice. In
addition, payment for goods and services rendered is typically due in the subsequent month following satisfaction of Southern
Power's performance obligation.
When multiple contracts exist with the same counterparty, the revenues from each contract are accounted for as separate
arrangements.
Southern Power may also enter into contracts to sell short-term capacity in the wholesale electricity markets. These sales are
generally classified as mark-to-market derivatives and net unrealized gains and losses on such contracts are recorded in wholesale
revenues. See Note 14 and "Financial Instruments" herein for additional information.

NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Southern Company Gas
Gas Distribution Operations
Southern Company Gas records revenues when goods or services are provided to customers. Those revenues are based on rates
approved by the state regulatory agencies of the natural gas distribution utilities. The natural gas market for Atlanta Gas Light was
deregulated in 1997. Accordingly, Marketers, rather than a traditional utility, sell natural gas to end-use customers in Georgia and
handle customer billing functions. As required by the Georgia PSC, Atlanta Gas Light bills Marketers in equal monthly
installments for each residential, commercial, and industrial end-use customer's distribution costs as well as for capacity costs
utilizing a seasonal rate design for the calculation of each residential end-use customer's annual straight-fixed-variable charge,
which reflects the historic volumetric usage pattern for the entire residential class.
The majority of the revenues of Southern Company Gas are generated from contracts with natural gas distribution customers.
Revenues from this integrated service to deliver gas when and if called upon by the customer is recognized as a single
performance obligation satisfied over time and is recognized at a tariff rate as gas is delivered to the customer during the month.
The standalone selling price is primarily determined by the price charged to customers for the specific goods or services
transferred with the performance obligations. Generally, Southern Company Gas recognizes revenue as the performance
obligations are satisfied over time as natural gas is delivered to the customer. The performance obligations related to wholesale
gas services are satisfied, and revenue is recognized, at a point in time when natural gas is delivered to the customer.
Southern Company Gas generally has a right to consideration in an amount that corresponds directly with the value to the
customer of the entity's performance completed to date and may recognize revenue in the amount to which the entity has a right to
invoice and has elected to recognize revenue for its sales of natural gas using the invoice practical expedient. In addition, payment
for goods and services rendered is typically due in the subsequent month following satisfaction of Southern Company Gas'
performance obligation.
With the exception of Atlanta Gas Light, the natural gas distribution utilities have rate structures that include volumetric rate
designs that allow the opportunity to recover certain costs based on gas usage. Revenues from sales and transportation services
are recognized in the same period in which the related volumes are delivered to customers. Revenues from residential and certain
commercial and industrial customers are recognized on the basis of scheduled meter readings. Additionally, unbilled revenues are
recognized for estimated deliveries of gas not yet billed to these customers, from the last bill date to the end of the accounting
period. For other commercial and industrial customers and for all wholesale customers, revenues are based on actual deliveries
through the end of the period.
The tariffs for several of the natural gas distribution utilities include provisions which allow for the recognition of certain
revenues prior to the time such revenues are billed to customers. These provisions are referred to as alternative revenue programs
and provide for the recognition of certain revenues prior to billing, as long as the amounts recognized will be collected from
customers within 24 months of recognition. These programs are as follows:
• Weather normalization adjustments – reduce customer bills when winter weather is colder than normal and increase
customer bills when weather is warmer than normal and are included in the tariffs for Virginia Natural Gas, Chattanooga
Gas, and, prior to its sale, Elizabethtown Gas;
• Revenue normalization mechanisms – mitigate the impact of conservation and declining customer usage and are
contained in the tariffs for Virginia Natural Gas, Chattanooga Gas, and, prior to its sale, Elkton Gas; and
• Revenue true-up adjustment – included within the provisions of the Georgia Rate Adjustment Mechanism (GRAM)
program in which Atlanta Gas Light participates as a short-term alternative to formal rate case filings, the revenue true-
up feature provides for a monthly positive (or negative) adjustment to record revenue in the amount of any variance to
budgeted revenues, which are submitted and approved annually as a requirement of GRAM. Such adjustments are
reflected in customer billings in a subsequent program year.
Wholesale Gas Services
Southern Company Gas nets revenues from energy and risk management activities with the associated costs. Profits from sales
between segments are eliminated and are recognized as goods or services sold to end-use customers. Southern Company Gas
records transactions that qualify as derivatives at fair value with changes in fair value recognized in earnings in the period of
change and characterized as unrealized gains or losses. Gains and losses on derivatives held for energy trading purposes are
presented on a net basis in revenue.
50
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Gas Marketing Services
Southern Company Gas recognizes revenues from natural gas sales and transportation services in the same period in which the
related volumes are delivered to customers and recognizes sales revenues from residential and certain commercial and industrial
customers on the basis of scheduled meter readings. Southern Company Gas also recognizes unbilled revenues for estimated
deliveries of gas not yet billed to these customers from the most recent meter reading date to the end of the accounting period. For
other commercial and industrial customers and for all wholesale customers, revenues are based on actual deliveries during the
period.
Southern Company Gas recognizes revenues on 12-month utility-bill management contracts as the lesser of cumulative earned or
cumulative billed amounts. Prior to the sale of Pivotal Home Solutions, revenues for warranty and repair contracts were
recognized on a straight-line basis over the contract term while revenues for maintenance services were recognized at the time
such services were performed. See Note 15 under "Southern Company Gas – Sale of Pivotal Home Solutions" for additional
information.
Concentration of Revenue
Southern Company, Alabama Power, Georgia Power, Mississippi Power (with the exception of its cost-based MRA electric tariffs
described below), and Southern Company Gas each have a diversified base of customers and no single customer or industry
comprises 10% or more of each company's revenues.
Mississippi Power serves long-term contracts with rural electric cooperative associations and municipalities located in
southeastern Mississippi under cost-based MRA electric tariffs, which are subject to regulation by the FERC. The contracts with
these wholesale customers represented 17.3% of Mississippi Power's total operating revenues in 2018 and are generally subject to
10-year rolling cancellation notices. Historically, these wholesale customers have acted as a group and any changes in contractual
relationships for one customer are likely to be followed by the other wholesale customers.
Significant portions of Southern Power's revenues have been derived from certain customers pursuant to PPAs. The following
table shows the percentage of total revenues for Southern Power's top three customers for each of the years presented:

On January 29, 2019, Pacific Gas & Electric Company (PG&E) filed petitions to reorganize under Chapter 11 of the U.S.
Bankruptcy Code. Southern Power, together with its noncontrolling partners, owns four solar facilities where PG&E is the energy
off-taker for approximately 207 MWs of capacity under long-term PPAs. PG&E is also the transmission provider for these
facilities and two of Southern Power's other solar facilities. Southern Power has evaluated the recoverability of its investments in
these solar facilities under various scenarios, including selling the related energy into the competitive markets, and has concluded
they are not impaired. At December 31, 2018, Southern Power had outstanding accounts receivables due from PG&E of $1
million related to the PPAs and $36 million related to the transmission interconnections (of which $17 million is classified in
other deferred charges and assets). Southern Power does not expect a material impact to its financial statements if, as a result of
the bankruptcy proceedings, PG&E does not perform in accordance with the PPAs or the terms of the PPAs are renegotiated;
however, the ultimate outcome of this matter cannot be determined at this time.
Fuel Costs
Fuel costs for the traditional electric operating companies and Southern Power are expensed as the fuel is used. Fuel expense
generally includes fuel transportation costs and the cost of purchased emissions allowances as they are used. For Alabama Power
and Georgia Power, fuel expense also includes the amortization of the cost of nuclear fuel. For the traditional electric operating
companies, fuel costs also include gains and/or losses from fuel-hedging programs as approved by their respective state PSCs.
Cost of Natural Gas
Excluding Atlanta Gas Light, which does not sell natural gas to end-use customers, Southern Company Gas charges its utility
customers for natural gas consumed using natural gas cost recovery mechanisms set by the applicable state regulatory agencies.
51
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Under these mechanisms, all prudently-incurred natural gas costs are passed through to customers without markup, subject to
regulatory review. Southern Company Gas defers or accrues the difference between the actual cost of natural gas and the amount
of commodity revenue earned in a given period such that no operating income is recognized related to these costs. The deferred or
accrued amount is either billed or refunded to customers prospectively through adjustments to the commodity rate. Deferred and
accrued natural gas costs are included in the balance sheets as regulatory assets and regulatory liabilities, respectively.
Southern Company Gas' gas marketing services' customers are charged for actual or estimated natural gas consumed. Within cost
of natural gas, Southern Company Gas also includes costs of lost and unaccounted for gas, adjustments to reduce the value of
inventories to market value, and gains and losses associated with certain derivatives.
Income Taxes
The registrants use the liability method of accounting for deferred income taxes and provide deferred income taxes for all
significant income tax temporary differences. In accordance with regulatory requirements, deferred federal ITCs for the
traditional electric operating companies and Southern Company Gas are amortized over the average lives of the related property,
with such amortization normally applied as a credit to reduce depreciation in the statements of income.
Under current tax law, certain projects at Southern Power related to the construction of renewable facilities are eligible for federal
ITCs. Southern Power estimates eligible costs which, as they relate to acquisitions, may not be finalized until the allocation of the
purchase price to assets has been finalized. Southern Power applies the deferred method to ITCs. Under the deferred method, the
ITCs are recorded as a deferred credit and amortized to income tax expense over the life of the respective asset. Furthermore, the
tax basis of the asset is reduced by 50% of the ITCs received, resulting in a net deferred tax asset. Southern Power has elected to
recognize the tax benefit of this basis difference as a reduction to income tax expense in the year in which the plant reaches
commercial operation. State ITCs are recognized as an income tax benefit in the period in which the credits are generated. In
addition, certain projects are eligible for federal and state PTCs, which are recognized as an income tax benefit based on KWH
production.
Federal ITCs and PTCs, as well as state ITCs and other state tax credits available to reduce income taxes payable, were not fully
utilized in 2018 and will be carried forward and utilized in future years. In addition, Southern Company is expected to have
various state net operating loss (NOL) carryforwards for certain of its subsidiaries, which would result in income tax benefits in
the future, if utilized. See Note 10 under "Current and Deferred Income Taxes – Tax Credit Carryforwards" and " – Net Operating
Loss Carryforwards" for additional information.
The registrants recognize tax positions that are "more likely than not" of being sustained upon examination by the appropriate
taxing authorities. See Note 10 under "Unrecognized Tax Benefits" for additional information.
Other Taxes
Taxes imposed on and collected from customers on behalf of governmental agencies are presented net on the registrants'
statements of income and are excluded from the transaction price in determining the revenue related to contracts with a customer
accounted for under ASC 606.
Southern Company Gas is taxed on its gas revenues by various governmental authorities, but is allowed to recover these taxes
from its customers. Revenue taxes imposed on the natural gas distribution utilities are recorded at the amount charged to
customers, which may include a small administrative fee, as operating revenues, and the related taxes imposed on Southern
Company Gas are recorded as operating expenses on the statements of income. Revenue taxes included in operating expenses
were $111 million and $98 million for the successor years ended December 31, 2018 and 2017, respectively, $31 million for the
successor period of July 1, 2016 through December 31, 2016, and $56 million for the predecessor period of January 1, 2016
through June 30, 2016.
Allowance for Funds Used During Construction and Interest Capitalized
The traditional electric operating companies and certain of the natural gas distribution utilities (Atlanta Gas Light, Chattanooga
Gas, and Nicor Gas) record AFUDC, which represents the estimated debt and equity costs of capital funds that are necessary to
finance the construction of new regulated facilities. While cash is not realized currently, AFUDC increases the revenue
requirement and is recovered over the service life of the asset through a higher rate base and higher depreciation. The equity
component of AFUDC is not taxable.
Interest related to the construction of new facilities at Southern Power and new facilities not included in the traditional electric
operating companies' and Southern Company Gas' regulated rates is capitalized in accordance with standard interest capitalization
requirements.

Impairment of Long-Lived Assets
The registrants evaluate long-lived assets and finite-lived intangible assets for impairment when events or changes in
circumstances indicate that the carrying value of such assets may not be recoverable. The determination of whether an impairment
has occurred is based on either a specific regulatory disallowance, a sales transaction price that is less than the asset group's
carrying value, or an estimate of undiscounted future cash flows attributable to the asset group, as compared with the carrying
value of the assets. If an impairment has occurred, the amount of the impairment recognized is determined by either the amount of
regulatory disallowance or by estimating the fair value of the assets and recording a loss if the carrying value is greater than the
fair value. For assets identified as held for sale, the carrying value is compared to the estimated fair value less the cost to sell in
order to determine if an impairment loss is required. Until the assets are disposed of, their estimated fair value is re-evaluated
when circumstances or events change. See Note 15 under "Southern Power" for information regarding impairment charges
recorded in 2018. Also see "Revenues" and "Leveraged Leases" herein and Note 3 under "Other Matters – Southern Company
Gas" for additional information.

Alabama Power Company 2018 Annual Report
Goodwill and Other Intangible Assets and Liabilities
Southern Power's intangible assets consist primarily of certain PPAs acquired, which are amortized over the term of the respective
PPA. Southern Company Gas' goodwill and other intangible assets and liabilities primarily relate to its 2016 acquisition by
Southern Company. In addition to these items, Southern Company's goodwill and other intangible assets also relate to its 2016
acquisition of PowerSecure. See Note 15 under "Southern Company Merger with Southern Company Gas" and "Southern
Company Acquisition of PowerSecure" for additional information.
Goodwill is not amortized, but is subject to an annual impairment test during the fourth quarter of each year, or more frequently if
impairment indicators arise. Southern Company Gas recorded a goodwill impairment charge in the first quarter 2018 related to its
disposition of Pivotal Home Solutions. Southern Company and Southern Company Gas each evaluated its goodwill in the fourth
quarter 2018 and determined no additional impairment was required. The following table presents 2018 changes in goodwill

(*) Excludes amounts related to held for sale assets. See Note 15 under "Southern Power – Sales of Natural Gas Plants" for additional information.
Included in other deferred credits and liabilities on the balance sheet is $91 million of intangible liabilities that were recorded
during acquisition accounting for transportation contracts at Southern Company Gas. At December 31, 2018, the accumulated
amortization of these intangible liabilities was $74 million. In 2019, the remaining $17 million of amortization associated with the
intangible liabilities will be recorded in natural gas revenues.
Acquisition Accounting
At the time of an acquisition, management will assess whether acquired assets and activities meet the definition of a business. For
acquisitions that meet the definition of a business, operating results from the date of acquisition are included in the acquiring
entity's financial statements. The purchase price, including any contingent consideration, is allocated based on the fair value of the
identifiable assets acquired and liabilities assumed (including any intangible assets). Assets acquired that do not meet the
definition of a business are accounted for as an asset acquisition.
The purchase price of each asset acquisition is allocated based on the relative fair value of assets acquired. Determining the fair
value of assets acquired and liabilities assumed requires management judgment and management may engage independent
valuation experts to assist in this process. Fair values are determined by using market participant assumptions and typically
include the timing and amounts of future cash flows, incurred construction costs, the nature of acquired contracts, discount rates,
power market prices, and expected asset lives. Any due diligence or transition costs incurred for potential or successful
acquisitions are expensed as incurred.
Historically, contingent consideration primarily relates to fixed amounts due to the seller once an acquired construction project is
placed in service. For contingent consideration with variable payments, management fair values the arrangement with any
changes recorded in the statements of income. See Note 13 for additional fair value information.
Development Costs
For Southern Power, development costs are capitalized once a project is probable of completion, primarily based on a review of
its economics and operational feasibility, as well as status of power off-take agreements and regulatory approvals, if applicable.
Southern Power's capitalized development costs are included in CWIP on the balance sheets. All of Southern Power's
development costs incurred prior to the determination that a project is probable of completion are expensed as incurred and
included in other operations and maintenance expense in the statements of income. If it is determined that a project is no longer
probable of completion, any of Southern Power's capitalized development costs are expensed and included in other operations and
maintenance expense in the statements of income.
Long-Term Service Agreements
The traditional electric operating companies and Southern Power have entered into LTSAs for the purpose of securing
maintenance support for certain of their generating facilities. The LTSAs cover all planned inspections on the covered equipment,
56
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
which generally includes the cost of all labor and materials. The LTSAs also obligate the counterparties to cover the costs of
unplanned maintenance on the covered equipment subject to limits and scope specified in each contract.
Payments made under the LTSAs for the performance of any planned inspections or unplanned capital maintenance are recorded
in the statements of cash flows as investing activities. Receipts of major parts into materials and supplies inventory prior to
planned inspections are treated as noncash transactions in the statements of cash flows. Any payments made prior to the work
being performed are recorded as prepayments in other current assets and noncurrent assets on the balance sheets. At the time work
is performed, an appropriate amount is accrued for future payments or transferred from the prepayment and recorded as property,
plant, and equipment or expensed.
Transmission Receivables/Prepayments
As a result of Southern Power's acquisition and construction of generating facilities, Southern Power has transmission receivables
and/or prepayments representing the portion of interconnection network and transmission upgrades that will be reimbursed to
Southern Power. Upon completion of the related project, transmission costs are generally reimbursed by the interconnection
provider within a five-year period and the receivable/prepayments are reduced as payments or services are received.
Cash and Cash Equivalents
For purposes of the financial statements, temporary cash investments are considered cash equivalents. Temporary cash
investments are securities with original maturities of 90 days or less.
Restricted Cash
The registrants adopted ASU 2016-18 as of January 1, 2018. See "Recently Adopted Accounting Standards – Other" herein for
additional information.
At December 31, 2018, Georgia Power had restricted cash related to the redemption of pollution control revenue bonds, which
were redeemed subsequent to December 31, 2018. See Note 8 under "Long-term Debt – Pollution Control Revenue Bonds" for
additional information. At December 31, 2017, Southern Power had restricted cash primarily related to certain acquisitions and
construction projects. At December 31, 2018 and 2017, Southern Company Gas had restricted cash held as collateral for worker's
compensation, life insurance, and long-term disability insurance.
The following tables provide a reconciliation of cash, cash equivalents, and restricted cash reported within the balance sheets that

Alabama Power and Mississippi Power also have authority based on orders from their state PSCs to accrue certain additional
amounts as circumstances warrant. There were no such additional accruals for Alabama Power and Mississippi Power in any year
presented.
See Note 2 under "Alabama Power – Rate NDR," "Georgia Power – Storm Damage Recovery," and "Mississippi Power – System

Leveraged Leases
A subsidiary of Southern Holdings has several leveraged lease agreements, with original terms ranging up to 45 years, which
relate to international and domestic energy generation, distribution, and transportation assets. Southern Company receives federal
income tax deductions for depreciation and amortization, as well as interest on long-term debt related to these investments.
Southern Company reviews all important lease assumptions at least annually, or more frequently if events or changes in
circumstances indicate that a change in assumptions has occurred or may occur. These assumptions include the effective tax rate,
the residual value, the credit quality of the lessees, and the timing of expected tax cash flows.
The ability of the lessees to make required payments to the Southern Holdings subsidiary is dependent on the operational
performance of the assets. In 2017, the financial and operational performance of one of the lessees and the associated generation
assets raised significant concerns about the short-term ability of the generation assets to produce cash flows sufficient to support
ongoing operations and the lessee's contractual obligations and its ability to make the remaining semi-annual lease payments to
the Southern Holdings subsidiary beginning in June 2018. As a result of operational improvements in 2018, the 2018 lease
payments were paid in full. However, operational issues and the resulting cash liquidity challenges persist and significant
concerns continue regarding the lessee's ability to make the remaining semi-annual lease payments. These operational challenges
may also impact the expected residual value of the assets at the end of the lease term in 2047. If any future lease payment is not
paid in full, the Southern Holdings subsidiary may be unable to make its corresponding payment to the holders of the underlying
non-recourse debt related to the generation assets. Failure to make the required payment to the debtholders could represent an
event of default that would give the debtholders the right to foreclose on, and take ownership of, the generation assets from the
Southern Holdings subsidiary, in effect terminating the lease and resulting in the write-off of the related lease receivable, which
would result in a reduction in net income of approximately $86 million after tax based on the lease receivable balance at
December 31, 2018. Southern Company has evaluated the recoverability of the lease receivable and the expected residual value of
58
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
the generation assets at the end of the lease under various scenarios and has concluded that its investment in the leveraged lease is
not impaired at December 31, 2018. Southern Company will continue to monitor the operational performance of the underlying
assets and evaluate the ability of the lessee to continue to make the required lease payments. The ultimate outcome of this matter
cannot be determined at this time.
Southern Company's net investment in domestic and international leveraged leases consists of the following at December 31:
Net rentals receivable
Unearned income

Materials and supplies for the traditional electric operating companies generally includes the average cost of transmission,
distribution, and generating plant materials. Materials and supplies for Southern Company Gas generally includes propane gas
inventory, fleet fuel, and other materials and supplies. Materials and supplies for Southern Power generally includes the average
cost of generating plant materials.
Materials are recorded to inventory when purchased and then expensed or capitalized to property, plant, and equipment, as
appropriate, at weighted average cost when installed. In addition, certain major parts are recorded as inventory when acquired and
then capitalized at cost when installed to property, plant, and equipment.
Fuel Inventory
Fuel inventory for the traditional electric operating companies includes the average cost of coal, natural gas, oil, transportation,
and emissions allowances. Fuel inventory for Southern Power, which is included in other current assets, includes the average cost
of oil, natural gas, biomass, and emissions allowances. Fuel is recorded to inventory when purchased and then expensed, at
weighted average cost, as used. Emissions allowances granted by the EPA are included in inventory at zero cost. The traditional
electric operating companies recover fuel expense through fuel cost recovery rates approved by each state PSC or, for wholesale
rates, the FERC.
Natural Gas for Sale
With the exception of Nicor Gas, the natural gas distribution utilities record natural gas inventories on a WACOG basis. In
Georgia's deregulated, competitive environment, Marketers sell natural gas to firm end-use customers at market-based prices. On
a monthly basis, Atlanta Gas Light assigns to Marketers the majority of the pipeline storage services that it has under contract,
along with a corresponding amount of inventory. Atlanta Gas Light retains and manages a portion of its pipeline storage assets
and related natural gas inventories for system balancing and to serve system demand.
Nicor Gas' natural gas inventory is carried at cost on a LIFO basis. Inventory decrements occurring during the year that are
restored prior to year end are charged to cost of natural gas at the estimated annual replacement cost. Inventory decrements that
are not restored prior to year end are charged to cost of natural gas at the actual LIFO cost of the inventory layers liquidated. The
cost of natural gas, including inventory costs, is recovered from customers under a purchased gas recovery mechanism adjusted
59
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
for differences between actual costs and amounts billed; therefore, LIFO liquidations have no impact on Southern Company's or
Southern Company Gas' net income. At December 31, 2018, the Nicor Gas LIFO inventory balance was $165 million. Based on
the average cost of gas purchased in December 2018, the estimated replacement cost of Nicor Gas' inventory at December 31,
2018 was $409 million. During 2018, Nicor Gas did not liquidate any LIFO-based inventory.
Southern Company Gas' gas marketing services, wholesale gas services, and all other segments record inventory at LOCOM, with
cost determined on a WACOG basis. For these segments, Southern Company Gas evaluates the weighted average cost of its
natural gas inventories against market prices to determine whether any declines in market prices below the WACOG are other
than temporary. For any declines considered to be other than temporary, Southern Company Gas recorded LOCOM adjustments
to cost of natural gas to reduce the value of its natural gas inventories to market value. LOCOM adjustments were $10 million
during 2018 for wholesale gas services and immaterial for all other periods presented.
Energy Marketing Receivables and Payables
Southern Company Gas' wholesale gas services provides services to retail gas marketers, wholesale gas marketers, utility
companies, and industrial customers. These counterparties utilize netting agreements that enable wholesale gas services to net
receivables and payables by counterparty upon settlement. Southern Company Gas' wholesale gas services also nets across
product lines and against cash collateral, provided the netting and cash collateral agreements include such provisions. While the
amounts due from, or owed to, wholesale gas services' counterparties are settled net, they are recorded on a gross basis in the
balance sheets as energy marketing receivables and energy marketing payables.
Southern Company Gas' wholesale gas services has trade and credit contracts that contain minimum credit rating requirements.
These credit rating requirements typically give counterparties the right to suspend or terminate credit if Southern Company Gas'
credit ratings are downgraded to non-investment grade status. Under such circumstances, Southern Company Gas' wholesale gas
services would need to post collateral to continue transacting business with some of its counterparties. As of December 31, 2018
and 2017, the required collateral in the event of a credit rating downgrade was $30 million and $8 million, respectively.
Credit policies were established to determine and monitor the creditworthiness of counterparties, including requirements to post
collateral or other credit security, as well as the quality of pledged collateral. Collateral or credit security is most often in the form
of cash or letters of credit from an investment-grade financial institution, but may also include cash or U.S. government securities
held by a trustee. When Southern Company Gas' wholesale gas services is engaged in more than one outstanding derivative
transaction with the same counterparty and it also has a legally enforceable netting agreement with that counterparty, the "net"
mark-to-market exposure represents the netting of the positive and negative exposures with that counterparty combined with a
reasonable measure of Southern Company Gas' credit risk. Southern Company Gas' wholesale gas services also uses other netting
agreements with certain counterparties with whom it conducts significant transactions.
See "Concentration of Credit Risk" herein for additional information.
Provision for Uncollectible Accounts
The customers of the traditional electric operating companies and natural gas distribution utilities are billed monthly. For the
majority of receivables, a provision for uncollectible accounts is established based on historical collection experience and other
factors. For the remaining receivables, if the company is aware of a specific customer's inability to pay, a provision for
uncollectible accounts is recorded to reduce the receivable balance to the amount reasonably expected to be collected. If
circumstances change, the estimate of the recoverability of accounts receivable could change as well. Circumstances that could
affect this estimate include, but are not limited to, customer credit issues, customer deposits, and general economic conditions.
Customers' accounts are written off once they are deemed to be uncollectible. For all periods presented, uncollectible accounts
averaged less than 1% of revenues for each registrant.
Credit risk exposure at Nicor Gas is mitigated by a bad debt rider approved by the Illinois Commission. The bad debt rider
provides for the recovery from (or refund to) customers of the difference between Nicor Gas' actual bad debt experience on an
annual basis and the benchmark bad debt expense used to establish its base rates for the respective year.
Concentration of Credit Risk
Southern Company Gas' wholesale gas services business has a concentration of credit risk for services it provides to its
counterparties. This credit risk is generally concentrated in 20 of its counterparties and is measured by 30-day receivable exposure
plus forward exposure. Counterparty credit risk is evaluated using a S&P equivalent credit rating, which is determined by a
process of converting the lower of the S&P or Moody's rating to an internal rating ranging from 9 to 1, with 9 being equivalent to
AAA/Aaa by S&P and Moody's, respectively, and 1 being equivalent to D/Default by S&P and Moody's, respectively. A
counterparty that does not have an external rating is assigned an internal rating based on the strength of its financial ratios. As of
60
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
December 31, 2018, the top 20 counterparties represented 48%, or $298 million, of the total counterparty exposure and had a
weighted average S&P equivalent rating of A-.
Concentration of credit risk occurs at Atlanta Gas Light for amounts billed for services and other costs to its customers, which
consist of 15 Marketers in Georgia (including SouthStar). The credit risk exposure to Marketers varies seasonally, with the lowest
exposure in the non-peak summer months and the highest exposure in the peak winter months. Marketers are responsible for the
retail sale of natural gas to end-use customers in Georgia. The functions of the retail sale of gas include the purchase and sale of
natural gas, customer service, billings, and collections. The provisions of Atlanta Gas Light's tariff allow Atlanta Gas Light to
obtain credit security support in an amount equal to a minimum of two times a Marketer's highest month's estimated bill from
Atlanta Gas Light.
Financial Instruments
The traditional electric operating companies and Southern Power use derivative financial instruments to limit exposure to
fluctuations in interest rates, the prices of certain fuel purchases, electricity purchases and sales, and occasionally foreign currency
exchange rates. Southern Company Gas uses derivative financial instruments to limit exposure to fluctuations in natural gas
prices, weather, interest rates, and commodity prices. All derivative financial instruments are recognized as either assets or
liabilities on the balance sheets (included in "Other" or shown separately as "Risk Management Activities") and are measured at
fair value. See Note 13 for additional information regarding fair value. Substantially all of the traditional electric operating
companies' and Southern Power's bulk energy purchases and sales contracts that meet the definition of a derivative are excluded
from fair value accounting requirements because they qualify for the "normal" scope exception, and are accounted for under the
accrual method. Derivative contracts that qualify as cash flow hedges of anticipated transactions or are recoverable through the
traditional electric operating companies' and the natural gas distribution utilities' fuel-hedging programs result in the deferral of
related gains and losses in AOCI or regulatory assets and liabilities, respectively, until the hedged transactions occur. For 2017
and 2016, ineffectiveness arising from cash flow hedges was recognized in net income. Upon the adoption of ASU 2017-12 in
2018, ineffectiveness is no longer separately measured and recorded in earnings. See "Recently Adopted Accounting Standards"
herein for additional information. Other derivative contracts that qualify as fair value hedges are marked to market through
current period income and are recorded on a net basis in the statements of income. Cash flows from derivatives are classified on
the statements of cash flows in the same category as the hedged item. See Note 14 for additional information regarding
derivatives.
The registrants offset fair value amounts recognized for multiple derivative instruments executed with the same counterparty
under netting arrangements. The registrants had no outstanding collateral repayment obligations or rights to reclaim collateral
arising from derivative instruments recognized at December 31, 2018.
The registrants are exposed to potential losses related to financial instruments in the event of counterparties' nonperformance. The
registrants have established risk management policies and controls to determine and monitor the creditworthiness of
counterparties in order to mitigate their exposure to counterparty credit risk.
Southern Company Gas
Southern Company Gas enters into weather derivative contracts as economic hedges of natural gas revenues in the event of
warmer-than-normal weather in the Heating Season. Exchange-traded options are carried at fair value, with changes reflected in
natural gas revenues. Non-exchange-traded options are accounted for using the intrinsic value method. Changes in the intrinsic
value for non-exchange-traded contracts are also reflected in natural gas revenues in the statements of income.
Wholesale gas services purchases natural gas for storage when the current market price paid to buy and transport natural gas plus
the cost to store and finance the natural gas is less than the market price that can be received in the future, resulting in positive net
natural gas revenues. NYMEX futures and OTC contracts are used to sell natural gas at that future price to substantially protect
the natural gas revenues that will ultimately be realized when the stored natural gas is sold. Southern Company Gas enters into
transactions to secure transportation capacity between delivery points in order to serve its customers and various markets.
NYMEX futures and OTC contracts are used to capture the price differential or spread between the locations served by the
capacity in order to substantially protect the natural gas revenues that will ultimately be realized when the physical flow of natural
gas between delivery points occurs. These contracts generally meet the definition of derivatives and are carried at fair value on the
balance sheets, with changes in fair value recorded in natural gas revenues on the statements of income in the period of change.
These contracts are not designated as hedges for accounting purposes.
The purchase, transportation, storage, and sale of natural gas are accounted for on a weighted average cost or accrual basis, as
appropriate, rather than on the fair value basis utilized for the derivatives used to mitigate the natural gas price risk associated
with the storage and transportation portfolio. Monthly demand charges are incurred for the contracted storage and transportation

capacity and payments associated with asset management agreements, and these demand charges and payments are recognized on
the statements of income in the period they are incurred. This difference in accounting methods can result in volatility in reported
earnings, even though the economic margin is substantially unchanged from the dates the transactions were consummated.
Comprehensive Income
The objective of comprehensive income is to report a measure of all changes in common stock equity of an enterprise that result
from transactions and other economic events of the period other than transactions with owners. Comprehensive income consists
of net income attributable to the registrant, changes in the fair value of qualifying cash flow hedges, and reclassifications for
amounts included in net income. Comprehensive income also consists of certain changes in pension and other postretirement
benefit plans for Southern Company, Southern Power, and Southern Company Gas.

Variable Interest Entities
The primary beneficiary of a VIE is required to consolidate the VIE when it has both the power to direct the activities of the VIE
that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits
from the VIE that could potentially be significant to the VIE. See Note 7 for additional information regarding VIEs.
Alabama Power has established a wholly-owned trust to issue preferred securities. See Note 8 under "Long-term Debt – Other

Gulf Power
On January 1, 2019, Southern Company completed its sale of Gulf Power to NextEra Energy. See Note 15 under "Southern
Company's Sale of Gulf Power" for additional information.
In accordance with a Florida PSC-approved settlement agreement, Gulf Power's rates effective for the first billing cycle in July
2017 increased by approximately $54 million annually (2017 Gulf Power Rate Case Settlement), including a $62 million increase
in base revenues, less an $8 million purchased power capacity cost recovery clause credit. The 2017 Rate Case Settlement
Agreement also resulted in a $32.5 million write-down of Gulf Power's ownership of Plant Scherer Unit 3, which was recorded in
the first quarter 2017.
As a continuation of the 2017 Gulf Power Rate Case Settlement Agreement, on March 26, 2018, the Florida PSC approved a
stipulation and settlement agreement addressing Gulf Power's retail revenue requirement effects of the Tax Reform Legislation
(Gulf Power Tax Reform Settlement Agreement). Beginning in April 1, 2018, the Gulf Power Tax Reform Settlement Agreement
resulted in annual reductions of approximately $18 million to Gulf Power's base rates and approximately $16 million to Gulf
Power's environmental cost recovery rates and a one-time refund of approximately $69 million for the retail portion of
unprotected (not subject to normalization) deferred tax liabilities, which was credited to customers through Gulf Power's fuel cost
recovery rates over the remainder of 2018.

NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Rate RSE
The Alabama PSC has adopted Rate RSE that provides for periodic annual adjustments based upon Alabama Power's projected
weighted common equity return (WCER) compared to an allowable range. Rate RSE adjustments are based on forward-looking
information for the applicable upcoming calendar year. Rate RSE adjustments for any two-year period, when averaged together,
cannot exceed 4.0% and any annual adjustment is limited to 5.0%. When the projected WCER is under the allowed range, there is
an adjusting point of 5.98% and eligibility for a performance-based adder of seven basis points, or 0.07%, to the WCER adjusting
point if Alabama Power (i) has an "A" credit rating equivalent with at least one of the recognized rating agencies or (ii) is in the
top one-third of a designated customer value benchmark survey. If Alabama Power's actual retail return is above the allowed
WCER range, the excess will be refunded to customers unless otherwise directed by the Alabama PSC; however, there is no
provision for additional customer billings should the actual retail return fall below the WCER range. Prior to January 2019, retail
rates remained unchanged when the WCER range was between 5.75% and 6.21%.
At December 31, 2016, Alabama Power's retail return exceeded the allowed WCER range which resulted in Alabama Power
establishing a $73 million Rate RSE refund liability. In accordance with an Alabama PSC order issued in February 2017, Alabama
Power applied the full amount of the refund to reduce the under recovered balance of Rate CNP PPA as discussed further below.
Effective in January 2017, Rate RSE increased 4.48%, or $245 million annually. At December 31, 2017, Alabama Power's actual
retail return was within the allowed WCER range. Retail rates under Rate RSE were unchanged for 2018.
In conjunction with Rate RSE, Alabama Power has an established retail tariff that provides for an adjustment to customer billings
to recognize the impact of a change in the statutory income tax rate. In accordance with this tariff, Alabama Power returned $267
million to retail customers through bill credits during 2018 as a result of the change in the federal income tax rate under the Tax
Reform Legislation.
On May 1, 2018, the Alabama PSC approved modifications to Rate RSE and other commitments designed to position Alabama
Power to address the growing pressure on its credit quality resulting from the Tax Reform Legislation, without increasing retail
rates under Rate RSE in the near term. Alabama Power plans to reduce growth in total debt by increasing equity, with
corresponding reductions in debt issuances, thereby de-leveraging its capital structure. Alabama Power's goal is to achieve an
equity ratio of approximately 55% by the end of 2025. At December 31, 2018, Alabama Power's equity ratio was approximately
47%.
The approved modifications to Rate RSE began for billings in January 2019. The modifications include reducing the top of the
allowed WCER range from 6.21% to 6.15% and modifications to the refund mechanism applicable to prior year actual results.
The modifications to the refund mechanism allow Alabama Power to retain a portion of the revenue that causes the actual WCER
for a given year to exceed the allowed range.
Generally, if Alabama Power's actual WCER is between 6.15% and 7.65%, customers will receive 25% of the amount between
6.15% and 6.65%, 40% of the amount between 6.65% and 7.15%, and 75% of the amount between 7.15% and 7.65%. Customers
will receive all amounts in excess of an actual WCER of 7.65%.
In conjunction with these modifications to Rate RSE, on May 8, 2018, Alabama Power consented to a moratorium on any upward
adjustments under Rate RSE for 2019 and 2020 and will also return $50 million to customers through bill credits in 2019.
On November 30, 2018, Alabama Power made its required annual Rate RSE submission to the Alabama PSC of projected data for
calendar year 2019. Projected earnings were within the specified range; therefore, retail rates under Rate RSE remain unchanged
for 2019.
At December 31, 2018, Alabama Power's retail return exceeded the allowed WCER range, which resulted in Alabama Power
establishing a regulatory liability of $109 million for Rate RSE refunds. In accordance with an Alabama PSC order issued on
February 5, 2019, Alabama Power will apply $75 million to reduce the Rate ECR under recovered balance and the remaining $34
million will be refunded to customers through bill credits in July through September 2019.
Rate CNP PPA
Alabama Power's retail rates, approved by the Alabama PSC, provide for adjustments under Rate CNP to recognize the placing of
new generating facilities into retail service. Alabama Power may also recover retail costs associated with certificated PPAs under
Rate CNP PPA. No adjustments to Rate CNP PPA occurred during the period 2016 through 2018 and no adjustment is expected in
2019. At December 31, 2018 and 2017, Alabama Power had an under recovered Rate CNP PPA balance of $25 million and $12
million, respectively, which is included in deferred under recovered regulatory clause revenues in the balance sheet.
In accordance with an accounting order issued in February 2017 by the Alabama PSC, Alabama Power eliminated the under
recovered balance in Rate CNP PPA at December 31, 2016, which totaled approximately $142 million. As discussed herein under
66
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
"Rate RSE," Alabama Power utilized the full amount of its $73 million Rate RSE refund liability to reduce the amount of the Rate
CNP PPA under recovery and reclassified the remaining $69 million to a separate regulatory asset. The amortization of the new
regulatory asset through Rate RSE will begin concurrently with the effective date of Alabama Power's next depreciation study,
which is expected to occur no later than 2022. Alabama Power's current depreciation study became effective January 1, 2017.
Rate CNP Compliance
Rate CNP Compliance allows for the recovery of Alabama Power's retail costs associated with laws, regulations, and other such
mandates directed at the utility industry involving the environment, security, reliability, safety, sustainability, or similar
considerations impacting Alabama Power's facilities or operations. Rate CNP Compliance is based on forward-looking
information and provides for the recovery of these costs pursuant to a factor that is calculated annually. Compliance costs to be
recovered include operations and maintenance expenses, depreciation, and a return on certain invested capital. Revenues for Rate
CNP Compliance, as recorded on the financial statements, are adjusted for differences in actual recoverable costs and amounts
billed in current regulated rates. Accordingly, changes in the billing factor will have no significant effect on Southern Company's
or Alabama Power's revenues or net income, but will affect annual cash flow. Changes in Rate CNP Compliance-related
operations and maintenance expenses and depreciation generally will have no effect on Southern Company's or Alabama Power's
net income.
In accordance with an accounting order issued in February 2017 by the Alabama PSC, Alabama Power reclassified $36 million of
its under recovered balance in Rate CNP Compliance to a separate regulatory asset. The amortization of the new regulatory asset
through Rate RSE will begin concurrently with the effective date of Alabama Power's next depreciation study, which is expected
to occur no later than 2022. Alabama Power's current depreciation study became effective January 1, 2017.
In December 2017, the Alabama PSC issued a consent order that Alabama Power leave in effect for 2018 the factors associated
with Alabama Power's compliance costs for the year 2017, with any under-collected amount for prior years deemed recovered
before any current year amounts.
On November 30, 2018, Alabama Power submitted calculations associated with its cost of complying with environmental
mandates, as provided under Rate CNP Compliance. The filing reflected a projected unrecovered retail revenue requirement for
environmental compliance of approximately $205 million, which is being recovered in the billing months of January 2019
through December 2019.
At December 31, 2018, Alabama Power had an under recovered Rate CNP Compliance balance of $42 million, which is included
in customer accounts receivable, and $17 million at December 31, 2017 included in deferred under recovered regulatory clause
revenues in the balance sheet.
Rate ECR
Alabama Power has established energy cost recovery rates under Alabama Power's Rate ECR as approved by the Alabama PSC.
Rates are based on an estimate of future energy costs and the current over or under recovered balance. Revenues recognized under
Rate ECR and recorded on the financial statements are adjusted for the difference in actual recoverable fuel costs and amounts
billed in current regulated rates. The difference in the recoverable fuel costs and amounts billed give rise to the over or under
recovered amounts recorded as regulatory assets or liabilities. Alabama Power, along with the Alabama PSC, continually monitors
the over or under recovered cost balance to determine whether an adjustment to billing rates is required. Changes in the Rate ECR
factor have no significant effect on Southern Company's or Alabama Power's net income, but will impact operating cash flows.
In accordance with an accounting order issued in February 2017 by the Alabama PSC, Alabama Power reclassified $36 million of
its under recovered balance in Rate ECR to a separate regulatory asset. The amortization of the new regulatory asset through Rate
RSE will begin concurrently with the effective date of Alabama Power's next depreciation study, which is expected to occur no
later than 2022. Alabama Power's current depreciation study became effective January 1, 2017.
In December 2017, the Alabama PSC issued a consent order that Alabama Power leave in effect for 2018 the energy cost recovery
rates which began in 2017.
On May 1, 2018, the Alabama PSC approved an increase to Rate ECR from 2.015 cents per KWH to 2.353 cents per KWH
effective July 2018 through December 2018. On December 4, 2018, the Alabama PSC issued a consent order to leave this rate in
effect through December 31, 2019. This change is expected to increase collections by approximately $183 million in 2019. Absent
any further order from the Alabama PSC, in January 2020, the rates will return to the originally authorized 5.910 cents per KWH.
As discussed herein under "Rate RSE," in accordance with an Alabama PSC order issued on February 5, 2019, Alabama Power
will utilize $75 million of the 2018 Rate RSE refund liability to reduce the Rate ECR under recovered balance.
67
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
At December 31, 2018, Alabama Power's under recovered fuel costs totaled $109 million, of which $18 million is included in
customer accounts receivable and $91 million is included in deferred under recovered regulatory clause revenues on Southern
Company's and Alabama Power's balance sheets. At December 31, 2017, Alabama Power had an under recovered fuel balance of
$25 million, which was included in deferred under recovered regulatory clause revenues on Southern Company's and Alabama
Power's balance sheets. These classifications are based on estimates, which include such factors as weather, generation
availability, energy demand, and the price of energy. A change in any of these factors could have a material impact on the timing
of any recovery or return of fuel costs.
Tax Reform Accounting Order
On May 1, 2018, the Alabama PSC approved an accounting order that authorized Alabama Power to defer the benefits of federal
excess deferred income taxes associated with the Tax Reform Legislation for the year ended December 31, 2018 as a regulatory
liability and to use up to $30 million of such deferrals to offset under recovered amounts under Rate ECR. The estimated deferrals
for the year ended December 31, 2018 totaled approximately $63 million, subject to adjustment following the filing of the 2018
tax return, of which $30 million was used to offset the Rate ECR under recovered balance and $33 million is recorded in other
regulatory liabilities, deferred on the balance sheet to be used for the benefit of customers as determined by the Alabama PSC at a
future date. See Note 10 under "Current and Deferred Income Taxes" for additional information.
Software Accounting Order
On February 5, 2019, the Alabama PSC approved an accounting order that authorizes Alabama Power to establish a regulatory
asset for operations and maintenance costs associated with software implementation projects. The regulatory asset will be
amortized ratably over the life of the related software.
Rate NDR
Based on an order from the Alabama PSC, Alabama Power maintains a reserve for operations and maintenance expenses to cover
the cost of damages from major storms to its transmission and distribution facilities. The order approves a separate monthly Rate
NDR charge to customers consisting of two components. The first component is intended to establish and maintain a reserve
balance for future storms and is an on-going part of customer billing. When the reserve balance falls below $50 million, a reserve
establishment charge will be activated (and the on-going reserve maintenance charge concurrently suspended) until the reserve
balance reaches $75 million. In December 2017, the reserve maintenance charge was suspended and the reserve establishment
charge was activated as a result of the NDR balance falling below $50 million. Alabama Power expects to collect approximately
$16 million annually until the reserve balance is restored to $75 million. The NDR balance at December 31, 2018 was $20 million
and is included in other regulatory liabilities, deferred on the balance sheet.
The second component of the Rate NDR charge is intended to allow recovery of any existing deferred storm-related operations
and maintenance costs and any future reserve deficits over a 24-month period. The Alabama PSC order gives Alabama Power
authority to record a deficit balance in the NDR when costs of storm damage exceed any established reserve balance. Absent
further Alabama PSC approval, the maximum total Rate NDR charge consisting of both components is $10 per month per non-
residential customer account and $5 per month per residential customer account. Alabama Power has the authority, based on an
order from the Alabama PSC, to accrue certain additional amounts as circumstances warrant. The order allows for reliability-
related expenditures to be charged against the additional accruals when the NDR balance exceeds $75 million. Alabama Power
may designate a portion of the NDR to reliability-related expenditures as a part of an annual budget process for the following year
or during the current year for identified unbudgeted reliability-related expenditures that are incurred. Accruals that have not been
designated can be used to offset storm charges. Additional accruals to the NDR will enhance Alabama Power's ability to deal with
the financial effects of future natural disasters, promote system reliability, and offset costs retail customers would otherwise bear.
No such accruals were recorded or designated in any period presented.
As revenue from the Rate NDR charge is recognized, an equal amount of operations and maintenance expenses related to the
NDR will also be recognized. As a result, the Rate NDR charge will not have an effect on net income but will impact operating
cash flows.
Environmental Accounting Order
Based on an order from the Alabama PSC (Environmental Accounting Order), Alabama Power is allowed to establish a regulatory
asset to record the unrecovered investment costs, including the unrecovered plant asset balance and the unrecovered costs
associated with site removal and closure associated with future unit retirements caused by environmental regulations. The
regulatory asset is being amortized and recovered over the affected unit's remaining useful life, as established prior to the decision
regarding early retirement through Rate CNP Compliance. At December 31, 2018, this regulatory asset had a balance of $42

million, of which $10 million is included in other regulatory assets, current and $32 million is included in other regulatory assets,
deferred on the balance sheet.
Subsequent to December 31, 2018, Alabama Power determined that Plant Gorgas Units 8, 9, and 10 (approximately 1,000 MWs)
will be retired by April 15, 2019 due to the expected costs of compliance with federal and state environmental regulations. In
accordance with the Environmental Accounting Order, approximately $740 million of net investment costs will be transferred to a
regulatory asset at the retirement date and recovered over the affected units' remaining useful lives, as established prior to the
decision to retire.

Alabama Power Company 2018 Annual Report
Rate Plans
Pursuant to the terms and conditions of a settlement agreement related to Southern Company's acquisition of Southern Company
Gas approved by the Georgia PSC in 2016, the 2013 ARP will continue in effect until December 31, 2019, and Georgia Power
will be required to file its next base rate case by July 1, 2019. Furthermore, through December 31, 2019, Georgia Power will
retain its merger savings, net of transition costs, as defined in the settlement agreement; through December 31, 2022, such net
merger savings will be shared on a 60/40 basis with customers; thereafter, all merger savings will be retained by customers.
There were no changes to Georgia Power's traditional base tariff rates, Environmental Compliance Cost Recovery (ECCR) tariff,
DSM tariffs, or Municipal Franchise Fee tariff in 2017 or 2018.
Under the 2013 ARP, Georgia Power's retail ROE is set at 10.95% and earnings are evaluated against a retail ROE range of
10.00% to 12.00%. Two-thirds of any earnings above 12.00% will be directly refunded to customers, with the remaining one-third
retained by Georgia Power. There will be no recovery of any earnings shortfall below 10.00% on an actual basis. In 2016, Georgia
Power's retail ROE exceeded 12.00%, and Georgia Power refunded to retail customers in 2018 approximately $40 million as
approved by the Georgia PSC. On February 5, 2019, the Georgia PSC approved a settlement between Georgia Power and the staff
of the Georgia PSC under which Georgia Power's retail ROE for 2017 was stipulated to exceed 12.00% and Georgia Power will
reduce certain regulatory assets by approximately $4 million in lieu of providing refunds to retail customers. In 2018, Georgia
Power's retail ROE exceeded 12.00%, and Georgia Power accrued approximately $100 million to refund to retail customers,
subject to review and approval by the Georgia PSC.
On April 3, 2018, the Georgia PSC approved the Georgia Power Tax Reform Settlement Agreement. Pursuant to the Georgia
Power Tax Reform Settlement Agreement, to reflect the federal income tax rate reduction impact of the Tax Reform Legislation,
Georgia Power will refund to customers a total of $330 million through bill credits. Georgia Power issued bill credits of
approximately $130 million in 2018 and will issue bill credits of approximately $95 million in June 2019 and $105 million in
February 2020. In addition, Georgia Power is deferring as a regulatory liability (i) the revenue equivalent of the tax expense
reduction resulting from legislation lowering the Georgia state income tax rate from 6.00% to 5.75% in 2019 and (ii) the entire
benefit of federal and state excess accumulated deferred income taxes, which is expected to total approximately $700 million at
December 31, 2019. At December 31, 2018, the related regulatory liability balance totaled $610 million. The amortization of
these regulatory liabilities is expected to be addressed in the Georgia Power 2019 Base Rate Case. If there is not a base rate case
in 2019, customers will receive $185 million in annual bill credits beginning in 2020, with any additional federal and state income
tax savings deferred as a regulatory liability, until Georgia Power's next base rate case.
To address some of the negative cash flow and credit quality impacts of the Tax Reform Legislation, the Georgia PSC also
approved an increase in Georgia Power's retail equity ratio to the lower of (i) Georgia Power's actual common equity weight in its
capital structure or (ii) 55%, until the Georgia Power 2019 Base Rate Case. At December 31, 2018, Georgia Power's actual retail
common equity ratio (on a 13-month average basis) was approximately 55%. Benefits from reduced federal income tax rates in
excess of the amounts refunded to customers will be retained by Georgia Power to cover the carrying costs of the incremental
equity in 2018 and 2019.
Integrated Resource Plan
In 2016, the Georgia PSC approved Georgia Power's triennial Integrated Resource Plan (2016 IRP) including the reclassification
of the remaining net book value of Plant Mitchell Unit 3 and costs associated with materials and supplies remaining at the unit
retirement date to a regulatory asset. Recovery of the unit's net book value will continue through December 31, 2019, as provided
in the 2013 ARP. The timing of the recovery of the remaining balance of the unit's net book value as of December 31, 2019 and
costs associated with materials and supplies remaining at the unit retirement date was deferred for consideration in the Georgia
Power 2019 Base Rate Case.
In the 2016 IRP, the Georgia PSC also approved recovery of costs up to $99 million through June 30, 2019 to preserve nuclear
generation as an option at a future generation site in Stewart County, Georgia. In March 2017, the Georgia PSC approved Georgia
Power's decision to suspend work at the site due to changing economics, including lower load forecasts and fuel costs. The timing
of recovery for costs incurred of approximately $50 million is expected to be determined by the Georgia PSC in the Georgia
Power 2019 Base Rate Case.
On January 31, 2019, Georgia Power filed its triennial IRP (2019 IRP). The filing includes a request to decertify and retire Plant
Hammond Units 1 through 4 (840 MWs) and Plant McIntosh Unit 1 (142.5 MWs) upon approval of the 2019 IRP.
In the 2019 IRP, Georgia Power requested approval to reclassify the remaining net book value of Plant Hammond Units 1 through
4 (approximately $520 million at December 31, 2018) upon retirement to a regulatory asset to be amortized ratably over a period
equal to the applicable unit's remaining useful life through 2035. For Plant McIntosh Unit 1, Georgia Power requested approval to
71
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
reclassify the remaining net book value (approximately $40 million at December 31, 2018) upon retirement to a regulatory asset
to be amortized over a three-year period to be determined in the Georgia Power 2019 Base Rate Case. Georgia Power also
requested approval to reclassify any unusable material and supplies inventory balances remaining at the applicable unit's
retirement date to a regulatory asset for recovery over a period to be determined in the Georgia Power 2019 Base Rate Case.
The 2019 IRP also includes a request to certify approximately 25 MWs of capacity at Plant Scherer Unit 3 for the retail
jurisdiction beginning January 1, 2020, following the expiration of a wholesale PPA.
The 2019 IRP also includes details regarding ARO costs associated with ash pond and landfill closures and post-closure care.
Georgia Power requested the timing and rate of recovery of these costs be determined by the Georgia PSC in the Georgia Power
2019 Base Rate Case. See Note 6 for additional information regarding Georgia Power's AROs.
Georgia Power also requested approval to issue two capacity-based requests for proposals (RFP). If approved, the first capacity-
based RFP will seek resources that can provide capacity beginning in 2022 or 2023 and the second capacity-based RFP will seek
resources that can provide capacity beginning in 2026, 2027, or 2028. Additionally, the 2019 IRP includes a request to procure an
additional 1,000 MWs of renewable resources through a competitive bidding process. Georgia Power also proposed to invest in a
portfolio of up to 50 MWs of battery energy storage technologies.
A decision from the Georgia PSC on the 2019 IRP is expected in mid-2019.
The ultimate outcome of these matters cannot be determined at this time.
Fuel Cost Recovery
Georgia Power has established fuel cost recovery rates approved by the Georgia PSC. In 2016, the Georgia PSC approved
Georgia Power's request to lower annual billings under an interim fuel rider by approximately $313 million effective June 1,
2016, which expired on December 31, 2017. On August 16, 2018, the Georgia PSC approved the deferral of Georgia Power's next
fuel case to no later than March 16, 2020, with new rates, if any, to be effective June 1, 2020. Georgia Power continues to be
allowed to adjust its fuel cost recovery rates under an interim fuel rider prior to the next fuel case if the under or over recovered
fuel balance exceeds $200 million. Georgia Power's under recovered fuel balance totaled $115 million and $165 million at
December 31, 2018 and 2017, respectively, and is included in under recovered fuel clause revenues on Southern Company's and
Georgia Power's balance sheets.
Georgia Power's fuel cost recovery mechanism includes costs associated with a natural gas hedging program, as revised and
approved by the Georgia PSC, allowing the use of an array of derivative instruments within a 48-month time horizon.
Fuel cost recovery revenues as recorded on the financial statements are adjusted for differences in actual recoverable fuel costs
and amounts billed in current regulated rates. Accordingly, changes in the billing factor will not have a significant effect on
Southern Company's or Georgia Power's revenues or net income, but will affect operating cash flows.
Storm Damage Recovery
Georgia Power defers and recovers certain costs related to damages from major storms as mandated by the Georgia PSC.
Beginning January 1, 2014, Georgia Power is accruing $30 million annually under the 2013 ARP that is recoverable through base
rates. At December 31, 2018 and 2017, the balance in the regulatory asset related to storm damage was $416 million and $333
million, respectively, with $30 million included in other regulatory assets, current for each year and $386 million and $303
million included in other regulatory assets, deferred, respectively. During October 2018, Hurricane Michael caused significant
damage to Georgia Power's transmission and distribution facilities. The incremental restoration costs related to this hurricane
deferred in the regulatory asset for storm damage totaled approximately $115 million. Hurricanes Irma and Matthew also caused
significant damage to Georgia Power's transmission and distribution facilities during September 2017 and October 2016,
respectively. The incremental restoration costs related to Hurricanes Irma and Matthew deferred in the regulatory asset for storm
damage totaled approximately $250 million. The rate of storm damage cost recovery is expected to be adjusted as part of the
Georgia Power 2019 Base Rate Case and further adjusted in future regulatory proceedings as necessary. The ultimate outcome of
this matter cannot be determined at this time.
Nuclear Construction
In 2009, the Georgia PSC certified construction of Plant Vogtle Units 3 and 4. Georgia Power holds a 45.7% ownership interest in
Plant Vogtle Units 3 and 4. In 2012, the NRC issued the related combined construction and operating licenses, which allowed full
construction of the two AP1000 nuclear units (with electric generating capacity of approximately 1,100 MWs each) and related
facilities to begin. Until March 2017, construction on Plant Vogtle Units 3 and 4 continued under the Vogtle 3 and 4 Agreement,
72
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
which was a substantially fixed price agreement. In March 2017, the EPC Contractor filed for bankruptcy protection under
Chapter 11 of the U.S. Bankruptcy Code.
In connection with the EPC Contractor's bankruptcy filing, Georgia Power, acting for itself and as agent for the Vogtle Owners,
entered into the Interim Assessment Agreement with the EPC Contractor to allow construction to continue. The Interim
Assessment Agreement expired in July 2017 when Georgia Power, acting for itself and as agent for the other Vogtle Owners, and
the EPC Contractor entered into the Vogtle Services Agreement. Under the Vogtle Services Agreement, Westinghouse provides
facility design and engineering services, procurement and technical support, and staff augmentation on a time and materials cost
basis. The Vogtle Services Agreement provides that it will continue until the start-up and testing of Plant Vogtle Units 3 and 4 are
complete and electricity is generated and sold from both units. The Vogtle Services Agreement is terminable by the Vogtle Owners
upon 30 days' written notice.
In October 2017, Georgia Power, acting for itself and as agent for the other Vogtle Owners, executed the Bechtel Agreement, a
cost reimbursable plus fee arrangement, whereby Bechtel is reimbursed for actual costs plus a base fee and an at-risk fee, which is
subject to adjustment based on Bechtel's performance against cost and schedule targets. Each Vogtle Owner is severally (not
jointly) liable for its proportionate share, based on its ownership interest, of all amounts owed to Bechtel under the Bechtel
Agreement. The Vogtle Owners may terminate the Bechtel Agreement at any time for their convenience, provided that the Vogtle
Owners will be required to pay amounts related to work performed prior to the termination (including the applicable portion of
the base fee), certain termination-related costs, and, at certain stages of the work, the applicable portion of the at-risk fee. Bechtel
may terminate the Bechtel Agreement under certain circumstances, including certain Vogtle Owner suspensions of work, certain
breaches of the Bechtel Agreement by the Vogtle Owners, Vogtle Owner insolvency, and certain other events. Pursuant to the
Loan Guarantee Agreement between Georgia Power and the DOE, Georgia Power is required to obtain the DOE's approval of the
Bechtel Agreement prior to obtaining any further advances under the Loan Guarantee Agreement.
Cost and Schedule
Georgia Power's approximate proportionate share of the remaining estimated capital cost to complete Plant Vogtle Units 3 and 4
by the expected in-service dates of November 2021 and November 2022, respectively, is as follows:
Base project capital cost forecast(a)(b)

$
(a) Excludes financing costs expected to be capitalized through AFUDC of approximately $315 million.
(b) Net of $1.7 billion received from Toshiba under the Guarantee Settlement Agreement and approximately $188 million in related Customer Refunds.
Georgia Power estimates that its financing costs for construction of Plant Vogtle Units 3 and 4 will total approximately $3.1
billion, of which $1.9 billion had been incurred through December 31, 2018.
As construction continues, challenges with management of contractors, subcontractors, and vendors; labor productivity,
availability, and/or cost escalation; procurement, fabrication, delivery, assembly, and/or installation and testing, including any
required engineering changes, of plant systems, structures, and components (some of which are based on new technology that
only recently began initial operation in the global nuclear industry at this scale); or other issues could arise and change the
projected schedule and estimated cost. Monthly construction production targets required to maintain the current project schedule
will continue to increase significantly throughout 2019. To meet these increasing monthly targets, existing craft construction
productivity must improve and additional craft laborers must be retained and deployed.
Georgia Power and Southern Nuclear believe it is a leading practice in connection with a construction project of this size and
complexity to periodically validate recent construction progress in comparison to the projected schedule and to verify and update
quantities of commodities remaining to install, labor productivity, and forecasted staffing needs. This verification process, led by
Southern Nuclear, was underway as of December 31, 2018 and is expected to be completed during the second quarter 2019.
Georgia Power currently does not anticipate any material changes to the total estimated project capital cost forecast for Plant
Vogtle Units 3 and 4 or the expected in-service dates of November 2021 and November 2022, respectively, resulting from this
verification process. However, the ultimate impact on cost and schedule, if any, will not be known until the verification process is
completed. Georgia Power is required to report the results and any project impacts to the Georgia PSC by May 15, 2019.
73
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
There have been technical and procedural challenges to the construction and licensing of Plant Vogtle Units 3 and 4 at the federal
and state level and additional challenges may arise. Processes are in place that are designed to assure compliance with the
requirements specified in the Westinghouse Design Control Document and the combined construction and operating licenses,
including inspections by Southern Nuclear and the NRC that occur throughout construction. As a result of such compliance
processes, certain license amendment requests have been filed and approved or are pending before the NRC. Various design and
other licensing-based compliance matters, including the timely resolution of ITAAC and the related approvals by the NRC, may
arise, which may result in additional license amendments or require other resolution. If any license amendment requests or other
licensing-based compliance issues are not resolved in a timely manner, there may be delays in the project schedule that could
result in increased costs.
The ultimate outcome of these matters cannot be determined at this time. However, any extension of the project schedule is
currently estimated to result in additional base capital costs of approximately $50 million per month, based on Georgia Power's
ownership interests, and AFUDC of approximately $12 million per month. While Georgia Power is not precluded from seeking
recovery of any future capital cost forecast increase, management will ultimately determine whether or not to seek recovery. Any
further changes to the capital cost forecast that are not expected to be recoverable through regulated rates will be required to be
charged to income and such charges could be material.
Joint Owner Contracts
In November 2017, the Vogtle Owners entered into an amendment to their joint ownership agreements for Plant Vogtle Units 3
and 4 to provide for, among other conditions, additional Vogtle Owner approval requirements. Effective August 31, 2018, the
Vogtle Owners further amended the joint ownership agreements to clarify and provide procedures for certain provisions of the
joint ownership agreements related to adverse events that require the vote of the holders of at least 90% of the ownership interests
in Plant Vogtle Units 3 and 4 to continue construction (as amended, and together with the November 2017 amendment, the Vogtle
Joint Ownership Agreements). The Vogtle Joint Ownership Agreements also confirm that the Vogtle Owners' sole recourse against
Georgia Power or Southern Nuclear for any action or inaction in connection with their performance as agent for the Vogtle
Owners is limited to removal of Georgia Power and/or Southern Nuclear as agent, except in cases of willful misconduct.
As a result of the increase in the total project capital cost forecast and Georgia Power's decision not to seek rate recovery of the
increase in the base capital costs as described below, the holders of at least 90% of the ownership interests in Plant Vogtle Units 3
and 4 were required to vote to continue construction. On September 26, 2018, the Vogtle Owners unanimously voted to continue
construction of Plant Vogtle Units 3 and 4.
Amendments to the Vogtle Joint Ownership Agreements
In connection with the vote to continue construction, Georgia Power entered into (i) a binding term sheet (Vogtle Owner Term
Sheet) with the other Vogtle Owners and MEAG's wholly-owned subsidiaries MEAG Power SPVJ, LLC (MEAG SPVJ), MEAG
Power SPVM, LLC (MEAG SPVM), and MEAG Power SPVP, LLC (MEAG SPVP) to take certain actions which partially
mitigate potential financial exposure for the other Vogtle Owners, including additional amendments to the Vogtle Joint Ownership
Agreements and the purchase of PTCs from the other Vogtle Owners, and (ii) a term sheet (MEAG Term Sheet) with MEAG and
MEAG SPVJ to provide funding with respect to MEAG SPVJ's ownership interest in Plant Vogtle Units 3 and 4 (Project J) under
certain circumstances. On January 14, 2019, Georgia Power, MEAG, and MEAG SPVJ entered into an agreement to implement
the provisions of the MEAG Term Sheet (MEAG Funding Agreement). On February 18, 2019, Georgia Power, the other Vogtle
Owners, and MEAG's wholly-owned subsidiaries MEAG SPVJ, MEAG SPVM, and MEAG SPVP entered into certain
amendments to the Vogtle Joint Ownership Agreements to implement the provisions of the Vogtle Owner Term Sheet (Global
Amendments).
Pursuant to the Global Amendments, and consistent with the Vogtle Owner Term Sheet, the Vogtle Joint Ownership Agreements
were modified as follows: (i) each Vogtle Owner must pay its proportionate share of qualifying construction costs for Plant Vogtle
Units 3 and 4 based on its ownership percentage up to the estimated cost at completion (EAC) for Plant Vogtle Units 3 and 4
which formed the basis of Georgia Power's forecast of $8.4 billion in the nineteenth VCM plus $800 million; (ii) Georgia Power
will be responsible for 55.7% of actual qualifying construction costs between $800 million and $1.6 billion over the EAC in the
nineteenth VCM (resulting in $80 million of potential additional costs to Georgia Power), with the remaining Vogtle Owners
responsible for 44.3% of such costs pro rata in accordance with their respective ownership interests; and (iii) Georgia Power will
be responsible for 65.7% of qualifying construction costs between $1.6 billion and $2.1 billion over the EAC in the nineteenth
VCM (resulting in a further $100 million of potential additional costs to Georgia Power), with the remaining Vogtle Owners
responsible for 34.3% of such costs pro rata in accordance with their respective ownership interests.
If the EAC is revised and exceeds the EAC in the nineteenth VCM by more than $2.1 billion, each of the other Vogtle Owners
will have a one-time option at the time the project budget forecast is so revised to tender a portion of its ownership interest to
74
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Georgia Power in exchange for Georgia Power's agreement to pay 100% of such Vogtle Owner's remaining share of total
construction costs in excess of the EAC in the nineteenth VCM plus $2.1 billion. In this event, Georgia Power will have the
option of cancelling the project in lieu of purchasing a portion of the ownership interest of any other Vogtle Owner. If Georgia
Power accepts the offer to purchase a portion of another Vogtle Owner's ownership interest in Plant Vogtle Units 3 and 4, the
ownership interest(s) to be conveyed from the tendering Vogtle Owner(s) to Georgia Power will be calculated based on the
proportion of the cumulative amount of construction costs paid by each such tendering Vogtle Owner(s) and by Georgia Power as
of the COD of Plant Vogtle Unit 4. For purposes of this calculation, payments made by Georgia Power on behalf of another Vogtle
Owner in accordance with the second and third items described in the paragraph above will be treated as payments made by the
applicable Vogtle Owner.
In the event the actual costs of construction at completion of a Unit are less than the EAC reflected in the nineteenth VCM report
and such Unit is placed in service in accordance with the schedule projected in the nineteenth VCM report (i.e., Plant Vogtle Unit
3 is placed in service by November 2021 or Plant Vogtle Unit 4 is placed in service by November 2022), Georgia Power will be
entitled to 60.7% of the cost savings with respect to the relevant Unit and the remaining Vogtle Owners will be entitled to 39.3%
of such savings on a pro rata basis in accordance with their respective ownership interests.
For purposes of the foregoing provisions, qualifying construction costs will not include costs (i) resulting from force majeure
events, including governmental actions or inactions (or significant delays associated with issuance of such actions) that affect the
licensing, completion, start-up, operations, or financing of Plant Vogtle Units 3 and 4, administrative proceedings or litigation
regarding ITAAC or other regulatory challenges to commencement of operation of Plant Vogtle Units 3 and 4, and changes in
laws or regulations governing Plant Vogtle Units 3 and 4, (ii) legal fees and legal expenses incurred due to litigation with
contractors or subcontractors that are not subsidiaries or affiliates of Southern Company, and (iii) additional costs caused by
requests from the Vogtle Owners other than Georgia Power, except for the exercise of a right to vote granted under the Vogtle
Joint Ownership Agreements, that increase costs by $100,000 or more.
Pursuant to the Global Amendments, and consistent with the Vogtle Owner Term Sheet, the provisions of the Vogtle Joint
Ownership Agreements requiring that Vogtle Owners holding 90% of the ownership interests in Plant Vogtle Units 3 and 4 vote to
continue construction following certain adverse events (Project Adverse Events) were modified. Pursuant to the Global
Amendments, the holders of at least 90% of the ownership interests in Plant Vogtle Units 3 and 4 must vote to continue
construction if certain Project Adverse Events occur, including: (i) the bankruptcy of Toshiba; (ii) the termination or rejection in
bankruptcy of certain agreements, including the Vogtle Services Agreement, the Bechtel Agreement, or the agency agreement with
Southern Nuclear; (iii) Georgia Power publicly announces its intention not to submit for rate recovery any portion of its
investment in Plant Vogtle Units 3 and 4 or the Georgia PSC determines that any of Georgia Power's costs relating to the
construction of Plant Vogtle Units 3 and 4 will not be recovered in retail rates, excluding any additional amounts paid by Georgia
Power on behalf of the other Vogtle Owners pursuant to the Global Amendments described above and the first 6% of costs during
any six-month VCM reporting period that are disallowed by the Georgia PSC for recovery, or for which Georgia Power elects not
to seek cost recovery, through retail rates; and (iv) an incremental extension of one year or more over the most recently approved
schedule. Under the Global Amendments, Georgia Power may cancel the project at any time in its sole discretion.
In addition, pursuant to the Vogtle Joint Ownership Agreements, the required approval of holders of ownership interests in Plant
Vogtle Units 3 and 4 is at least (i) 90% for a change of the primary construction contractor and (ii) 67% for material amendments
to the Vogtle Services Agreement or agreements with Southern Nuclear or the primary construction contractor, including the
Bechtel Agreement.
The Global Amendments provide that if the holders of at least 90% of the ownership interests fail to vote in favor of continuing
the project following any future Project Adverse Event, work on Plant Vogtle Units 3 and 4 will continue for a period of 30 days if
the holders of more than 50% of the ownership interests vote in favor of continuing construction (Majority Voting Owners). In
such a case, the Vogtle Owners (i) have agreed to negotiate in good faith towards the resumption of the project, (ii) if no
agreement is reached during such 30-day period, the project will be cancelled, and (iii) in the event of such a cancellation, the
Majority Voting Owners will be obligated to reimburse any other Vogtle Owner for the incremental costs it incurred during such
30-day negotiation period.
Purchase of PTCs During Commercial Operation
Pursuant to the Global Amendments, and consistent with the Vogtle Owner Term Sheet, Georgia Power has agreed to purchase
additional PTCs from OPC, Dalton, MEAG SPVM, MEAG SPVP, and MEAG SPVJ (to the extent any MEAG SPVJ PTC rights
remain after any purchases required under the MEAG Funding Agreement as described below) at varying purchase prices
dependent upon the actual cost to complete construction of Plant Vogtle Units 3 and 4 as compared to the EAC reflected in the
nineteenth VCM report. The purchases are at the option of the applicable Vogtle Owner.

Potential Funding to MEAG Project J
Pursuant to the MEAG Funding Agreement, and consistent with the MEAG Term Sheet, if MEAG SPVJ is unable to make its
payments due under the Vogtle Joint Ownership Agreements solely as a result of the occurrence of one of the following situations
that materially impedes access to capital markets for MEAG for Project J: (i) the conduct of JEA or the City of Jacksonville, such
as JEA's legal challenges of its obligations under a PPA with MEAG (PPA-J), or (ii) PPA-J is declared void by a court of
competent jurisdiction or rejected by JEA under the applicable provisions of the U.S. Bankruptcy Code (each of (i) and (ii), a JEA
Default), at MEAG's request, Georgia Power will purchase from MEAG SPVJ the rights to PTCs attributable to MEAG SPVJ's
share of Plant Vogtle Units 3 and 4 (approximately 206 MWs) within 30 days of such request at varying prices dependent upon
the stage of construction of Plant Vogtle Units 3 and 4. The aggregate purchase price of the PTCs, together with any advances
made as described in the next paragraph, shall not exceed $300 million.
At the option of MEAG, as an alternative or supplement to Georgia Power's purchase of PTCs as described above, Georgia Power
has agreed to provide up to $250 million in funding to MEAG for Project J in the form of advances (either advances under the
Vogtle Joint Ownership Agreements or the purchase of MEAG Project J bonds, at the discretion of Georgia Power), subject to any
required approvals of the Georgia PSC and the DOE.
In the event MEAG SPVJ certifies to Georgia Power that it is unable to fund its obligations under the Vogtle Joint Ownership
Agreements as a result of a JEA Default and Georgia Power becomes obligated to provide funding as described above, MEAG is
required to (i) assign to Georgia Power its right to vote on any future Project Adverse Event and (ii) diligently pursue JEA for its
breach of PPA-J. In addition, Georgia Power agreed that it will not sue MEAG for any amounts due from MEAG SPVJ under
MEAG's guarantee of MEAG SPVJ's obligations so long as MEAG SPVJ complies with the terms of the MEAG Funding
Agreement as to its payment obligations and the other non-payment provisions of the Vogtle Joint Ownership Agreements.
Under the terms of the MEAG Funding Agreement, Georgia Power may cancel the project in lieu of providing funding in the
form of advances or PTC purchases.
The ultimate outcome of these matters cannot be determined at this time.
Regulatory Matters
In 2009, the Georgia PSC voted to certify construction of Plant Vogtle Units 3 and 4 with a certified capital cost of $4.418 billion.
In addition, in 2009 the Georgia PSC approved inclusion of the Plant Vogtle Units 3 and 4 related CWIP accounts in rate base,
and the State of Georgia enacted the Georgia Nuclear Energy Financing Act, which allows Georgia Power to recover financing
costs for Plant Vogtle Units 3 and 4. Financing costs are recovered on all applicable certified costs through annual adjustments to
the NCCR tariff up to the certified capital cost of $4.418 billion. At December 31, 2018, Georgia Power had recovered
approximately $1.9 billion of financing costs. Financing costs related to capital costs above $4.418 billion will be recovered
through AFUDC; however, Georgia Power will not record AFUDC related to any capital costs in excess of the total deemed
reasonable by the Georgia PSC (currently $7.3 billion) and not requested for rate recovery. On December 18, 2018, the Georgia
PSC approved Georgia Power's request to increase the NCCR tariff by $88 million annually, effective January 1, 2019.
Georgia Power is required to file semi-annual VCM reports with the Georgia PSC by February 28 and August 31 of each year. In
2013, in connection with the eighth VCM report, the Georgia PSC approved a stipulation between Georgia Power and the staff of
the Georgia PSC to waive the requirement to amend the Plant Vogtle Units 3 and 4 certificate in accordance with the 2009
certification order until the completion of Plant Vogtle Unit 3, or earlier if deemed appropriate by the Georgia PSC and Georgia
Power.
In 2016, the Georgia PSC voted to approve a settlement agreement (Vogtle Cost Settlement Agreement) resolving certain
prudency matters in connection with the fifteenth VCM report. In December 2017, the Georgia PSC voted to approve (and issued
its related order on January 11, 2018) Georgia Power's seventeenth VCM report, which included a recommendation to continue
construction with Southern Nuclear as project manager and Bechtel serving as the primary construction contractor, and modified
the Vogtle Cost Settlement Agreement. The Vogtle Cost Settlement Agreement, as modified by the January 11, 2018 order,
resolved the following regulatory matters related to Plant Vogtle Units 3 and 4: (i) none of the $3.3 billion of costs incurred
through December 31, 2015 and reflected in the fourteenth VCM report should be disallowed from rate base on the basis of
imprudence; (ii) the Contractor Settlement Agreement was reasonable and prudent and none of the amounts paid pursuant to the
Contractor Settlement Agreement should be disallowed from rate base on the basis of imprudence; (iii) (a) capital costs incurred
up to $5.68 billion would be presumed to be reasonable and prudent with the burden of proof on any party challenging such costs,
(b) Georgia Power would have the burden to show that any capital costs above $5.68 billion were prudent, and (c) a revised
capital cost forecast of $7.3 billion (after reflecting the impact of payments received under the Guarantee Settlement Agreement
and related Customer Refunds) was found reasonable; (iv) construction of Plant Vogtle Units 3 and 4 should be completed, with
Southern Nuclear serving as project manager and Bechtel as primary contractor; (v) approved and deemed reasonable Georgia
76
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Power's revised schedule placing Plant Vogtle Units 3 and 4 in service in November 2021 and November 2022, respectively; (vi)
confirmed that the revised cost forecast does not represent a cost cap and that prudence decisions on cost recovery will be made at
a later date, consistent with applicable Georgia law; (vii) reduced the ROE used to calculate the NCCR tariff (a) from 10.95% (the
ROE rate setting point authorized by the Georgia PSC in the 2013 ARP) to 10.00% effective January 1, 2016, (b) from 10.00% to
8.30%, effective January 1, 2020, and (c) from 8.30% to 5.30%, effective January 1, 2021 (provided that the ROE in no case will
be less than Georgia Power's average cost of long-term debt); (viii) reduced the ROE used for AFUDC equity for Plant Vogtle
Units 3 and 4 from 10.00% to Georgia Power's average cost of long-term debt, effective January 1, 2018; and (ix) agreed that
upon Unit 3 reaching commercial operation, retail base rates would be adjusted to include carrying costs on those capital costs
deemed prudent in the Vogtle Cost Settlement Agreement. The January 11, 2018 order also stated that if Plant Vogtle Units 3 and
4 are not commercially operational by June 1, 2021 and June 1, 2022, respectively, the ROE used to calculate the NCCR tariff
will be further reduced by 10 basis points each month (but not lower than Georgia Power's average cost of long-term debt) until
the respective Unit is commercially operational. The ROE reductions negatively impacted earnings by approximately $100
million, $25 million, and $20 million in 2018, 2017, and 2016, respectively, and are estimated to have negative earnings impacts
of approximately $75 million in 2019 and an aggregate of approximately $615 million from 2020 to 2022.
In its January 11, 2018 order, the Georgia PSC also stated if other conditions change and assumptions upon which Georgia
Power's seventeenth VCM report are based do not materialize, the Georgia PSC reserved the right to reconsider the decision to
continue construction.
On February 12, 2018, Georgia Interfaith Power & Light, Inc. (GIPL) and Partnership for Southern Equity, Inc. (PSE) filed a
petition appealing the Georgia PSC's January 11, 2018 order with the Fulton County Superior Court. On March 8, 2018, Georgia
Watch filed a similar appeal to the Fulton County Superior Court for judicial review of the Georgia PSC's decision and denial of
Georgia Watch's motion for reconsideration. On December 21, 2018, the Fulton County Superior Court granted Georgia Power's
motion to dismiss the two appeals. On January 9, 2019, GIPL, PSE, and Georgia Watch filed an appeal of this decision with the
Georgia Court of Appeals. Georgia Power believes the appeal has no merit; however, an adverse outcome in the appeal combined
with subsequent adverse action by the Georgia PSC could have a material impact on Southern Company's and Georgia Power's
results of operations, financial condition, and liquidity.
In preparation for its nineteenth VCM filing, Georgia Power requested Southern Nuclear to perform a full cost reforecast for the
project. This reforecast, performed prior to the nineteenth VCM filing, resulted in a $0.7 billion increase to the base capital cost
forecast reported in the second quarter 2018. This base cost increase primarily resulted from changed assumptions related to the
finalization of contract scopes and management responsibilities for Bechtel and over 60 subcontractors, labor productivity rates,
and craft labor incentives, as well as the related levels of project management, oversight, and support, including field supervision
and engineering support.
Although Georgia Power believes these incremental costs are reasonable and necessary to complete the project and the Georgia
PSC's order in the seventeenth VCM proceeding specifically states that the construction of Plant Vogtle Units 3 and 4 is not
subject to a cost cap, Georgia Power did not seek rate recovery for these cost increases included in the current base capital cost
forecast (or any related financing costs) in the nineteenth VCM report. In connection with future VCM filings, Georgia Power
may request the Georgia PSC to evaluate costs currently included in the construction contingency estimate for rate recovery as
and when they are appropriately included in the base capital cost forecast. After considering the significant level of uncertainty
that exists regarding the future recoverability of costs included in the construction contingency estimate since the ultimate
outcome of these matters is subject to the outcome of future assessments by management, as well as Georgia PSC decisions in
these future regulatory proceedings, Georgia Power recorded a total pre-tax charge to income of $1.1 billion ($0.8 billion after
tax) in the second quarter 2018, which includes the total increase in the base capital cost forecast and construction contingency
estimate.
On August 31, 2018, Georgia Power filed its nineteenth VCM report with the Georgia PSC, which requested approval of $578
million of construction capital costs incurred from January 1, 2018 through June 30, 2018. On February 19, 2019, the Georgia
PSC approved the nineteenth VCM, but deferred approval of $51.6 million of expenditures related to Georgia Power's portion of
an administrative claim filed in the Westinghouse bankruptcy proceedings. Through the nineteenth VCM, the Georgia PSC has
approved total construction capital costs incurred through June 30, 2018 of $5.4 billion (before $1.7 billion of payments received
under the Guarantee Settlement Agreement and approximately $188 million in related Customer Refunds). In addition, the staff of
the Georgia PSC requested, and Georgia Power agreed, to file its twentieth VCM report concurrently with the twenty-first VCM
report by August 31, 2019.
The ultimate outcome of these matters cannot be determined at this time.

DOE Financing
At December 31, 2018, Georgia Power had borrowed $2.6 billion related to Plant Vogtle Units 3 and 4 costs through the Loan
Guarantee Agreement and a multi-advance credit facility among Georgia Power, the DOE, and the FFB, which provides for
borrowings of up to $3.46 billion, subject to the satisfaction of certain conditions. In September 2017, the DOE issued a
conditional commitment to Georgia Power for up to approximately $1.67 billion in additional guaranteed loans under the Loan
Guarantee Agreement. In September 2018, the DOE extended the conditional commitment to March 31, 2019. Any further
extension must be approved by the DOE. Final approval and issuance of these additional loan guarantees by the DOE cannot be
assured and are subject to the negotiation of definitive agreements, completion of due diligence by the DOE, receipt of any
necessary regulatory approvals, and satisfaction of other conditions. See Note 8 under "Long-term Debt – DOE Loan Guarantee
Borrowings" for additional information, including applicable covenants, events of default, mandatory prepayment events
(including any decision not to continue construction of Plant Vogtle Units 3 and 4), and conditions to borrowing.

Alabama Power Company 2018 Annual Report
Operations Review
In August 2018, the Mississippi PSC began an operations review of Mississippi Power, for which the final report is expected prior
to the conclusion of the Mississippi Power 2019 Base Rate Case. Mississippi Power expects that the review will include, but not
be limited to, a comparative analysis of its costs, its cost recovery framework, and ways in which it may streamline management
operations for the reasonable benefit of ratepayers. The ultimate outcome of this matter cannot be determined at this time.
Performance Evaluation Plan
Mississippi Power's retail base rates generally are set under the PEP, a rate plan approved by the Mississippi PSC. Two filings are
made for each calendar year: the PEP projected filing, which is typically filed prior to the beginning of the year based on a
projected revenue requirement, and the PEP lookback filing, which is filed after the end of the year and allows for review of the
actual revenue requirement compared to the projected filing.
In 2011, Mississippi Power submitted its annual PEP lookback filing for 2010, which recommended no surcharge or refund. Later
in 2011, the MPUS disputed certain items in the 2010 PEP lookback filing. In 2012, the Mississippi PSC issued an order
canceling Mississippi Power's PEP lookback filing for 2011. In 2013, the MPUS contested Mississippi Power's PEP lookback
filing for 2012, which indicated a refund due to customers of $5 million. In 2014 through 2018, Mississippi Power submitted its
annual PEP lookback filings for the prior years, which for each of 2013, 2014, and 2017 indicated no surcharge or refund and for
each of 2015 and 2016 indicated a $5 million surcharge. Additionally, in July 2016, in November 2016, and in November 2017,
Mississippi Power submitted its annual projected PEP filings for 2016, 2017, and 2018, respectively, which for 2016 and 2017
indicated no change in rates and for 2018 indicated a rate increase of 4%, or $38 million in annual revenues. The Mississippi PSC
suspended each of these filings to allow more time for review.
On February 7, 2018, Mississippi Power revised its annual projected PEP filing for 2018 to reflect the impacts of the Tax Reform
Legislation. The revised filing requested an increase of $26 million in annual revenues, based on a performance adjusted ROE of
9.33% and an increased equity ratio of 55%. On July 27, 2018, Mississippi Power and the MPUS entered into a settlement
agreement, which was approved by the Mississippi PSC on August 7, 2018, with respect to the 2018 PEP filing and all unresolved
PEP filings for prior years (PEP Settlement Agreement). Rates under the PEP Settlement Agreement became effective with the
first billing cycle of September 2018. The PEP Settlement Agreement provides for an increase of approximately $21.6 million in
annual base retail revenues, which excludes certain compensation costs contested by the MPUS, as well as approximately $2
million which was subsequently approved for recovery through the 2018 Energy Efficiency Cost Rider as discussed below. Under
the PEP Settlement Agreement, Mississippi Power is deferring the contested compensation costs for 2018 and 2019 as a
regulatory asset, which totaled $4 million as of December 31, 2018 and is included in other regulatory assets, deferred on the
balance sheet. The Mississippi PSC is currently expected to rule on the appropriate treatment for such costs in connection with the
Mississippi Power 2019 Base Rate Case. The ultimate outcome of this matter cannot be determined at this time.
Pursuant to the PEP Settlement Agreement, Mississippi Power's performance-adjusted allowed ROE is 9.31% and its allowed
equity ratio is capped at 51%, pending further review by the Mississippi PSC. In lieu of the requested equity ratio increase,
Mississippi Power retained $44 million of excess accumulated deferred income taxes resulting from the Tax Reform Legislation
until the conclusion of the Mississippi Power 2019 Base Rate Case. Further, Mississippi Power agreed to seek equity
contributions sufficient to restore its equity ratio to 50% by December 31, 2018. Since Mississippi Power's actual average equity
ratio for 2018 was more than 1% lower than the 50% target, Mississippi Power deferred the corresponding difference in its
revenue requirement of approximately $4 million as a regulatory liability for resolution in the Mississippi Power 2019 Base Rate
Case. Pursuant to the PEP Settlement Agreement, PEP proceedings are suspended until after the conclusion of the Mississippi
Power 2019 Base Rate Case and Mississippi Power is not required to make any PEP filings for regulatory years 2018, 2019, and
2020. The PEP Settlement Agreement also resolved all open PEP filings with no change to customer rates. As a result, in the third
quarter 2018, Mississippi Power recognized revenues of $5 million previously reserved in connection with the 2012 PEP
lookback filing.
Energy Efficiency
In 2013, the Mississippi PSC approved an energy efficiency and conservation rule requiring electric and gas utilities in
Mississippi serving more than 25,000 customers to implement energy efficiency programs and standards. Quick Start Plans,
which include a portfolio of energy efficiency programs that are intended to provide benefits to a majority of customers, were
extended by an order issued by the Mississippi PSC in July 2016, until the time the Mississippi PSC approves a comprehensive
portfolio plan program. The ultimate outcome of this matter cannot be determined at this time.

NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
On May 8, 2018, the Mississippi PSC issued an order approving Mississippi Power's revised annual projected Energy Efficiency
Cost Rider 2018 compliance filing, which increased annual retail revenues by approximately $3 million effective with the first
billing cycle for June 2018.
On February 5, 2019, the Mississippi PSC issued an order approving Mississippi Power's Energy Efficiency Cost Rider 2019
compliance filing, which included a slight decrease in annual retail revenues, effective with the first billing cycle in March 2019.
Environmental Compliance Overview Plan
In accordance with a 2011 accounting order from the Mississippi PSC, Mississippi Power has the authority to defer in a
regulatory asset for future recovery all plant retirement- or partial retirement-related costs resulting from environmental
regulations. The Mississippi PSC approved $41 million and $17 million of costs that were reclassified to regulatory assets
associated with the fuel conversion of Plant Watson and Plant Greene County, respectively, for amortization over five-year
periods that began in July 2016 and July 2017, respectively. As a result, these decisions are not expected to have a material impact
on Mississippi Power's financial statements.
In August 2016, the Mississippi PSC approved Mississippi Power's revised ECO Plan filing for 2016, which requested the
maximum 2% annual increase in revenues, or approximately $18 million, primarily related to the Plant Daniel Units 1 and 2
scrubbers placed in service in 2015. The revised rates became effective with the first billing cycle for September 2016.
Approximately $22 million of related revenue requirements in excess of the 2% maximum was deferred for inclusion in the 2017
filing, along with related carrying costs.
In May 2017, the Mississippi PSC approved Mississippi Power's ECO Plan filing for 2017, which requested the maximum 2%
annual increase in revenues, or approximately $18 million, primarily related to the carryforward from the prior year. The rates
became effective with the first billing cycle for June 2017. Approximately $26 million, plus carrying costs, of related revenue
requirements in excess of the 2% maximum was deferred for inclusion in the 2018 filing.
On February 14, 2018, Mississippi Power submitted its ECO Plan filing for 2018, including the effects of the Tax Reform
Legislation, which requested the maximum 2% annual increase in revenues, or approximately $17 million, primarily related to the
carryforward from the prior year.
On August 3, 2018, Mississippi Power and the MPUS entered into the ECO Settlement Agreement, which provides for an
increase of approximately $17 million in annual base retail revenues and was approved by the Mississippi PSC on August 7,
2018. Rates under the ECO Settlement Agreement became effective with the first billing cycle of September 2018 and will
continue in effect until modified by the Mississippi PSC. These revenues are expected to be sufficient to recover the costs
included in Mississippi Power's request for 2018, as well as the remaining deferred amounts, totaling $26 million at December 31,
2018, along with the related carrying costs. In accordance with the ECO Settlement Agreement, ECO Plan proceedings are
suspended until after the conclusion of the Mississippi Power 2019 Base Rate Case and Mississippi Power is not required to make
any ECO Plan filings for 2018, 2019, and 2020, with any necessary adjustments to be reflected in the Mississippi Power 2019
Base Rate Case. The ECO Settlement Agreement contains the same terms as the PEP Settlement Agreement described herein with
respect to allowed ROE and equity ratio. At December 31, 2018, Mississippi Power has recorded $2 million in other regulatory
liabilities, deferred on the balance sheet related to the actual December 31, 2018 average equity ratio differential from target
applicable to the ECO Plan.
Fuel Cost Recovery
Mississippi Power establishes, annually, a retail fuel cost recovery factor that is approved by the Mississippi PSC. Mississippi
Power is required to file for an adjustment to the retail fuel cost recovery factor annually. In January 2017, the Mississippi PSC
approved the 2017 retail fuel cost recovery factor, effective February 2017 through January 2018, which resulted in an annual
revenue increase of $55 million. On January 16, 2018, the Mississippi PSC approved the 2018 retail fuel cost recovery factor,
effective February 2018 through January 2019, which resulted in an annual revenue increase of $39 million. At December 31,
2018, the amount of over recovered retail fuel costs included in the balance sheet in other accounts payable was approximately $8
million compared to $6 million under recovered at December 31, 2017. On January 10, 2019, the Mississippi PSC approved the
2019 retail fuel cost recovery factor, effective February 2019, which results in a $35 million decrease in annual revenues as a
result of lower expected fuel costs.
Mississippi Power's operating revenues are adjusted for differences in actual recoverable fuel cost and amounts billed in
accordance with the currently approved cost recovery rate. Accordingly, changes in the billing factor should have no significant
effect on Southern Company's or Mississippi Power's revenues or net income but will affect operating cash flows.

Mississippi Power carries insurance for the cost of certain types of damage to generation plants and general property. However,
Mississippi Power is self-insured for the cost of storm, fire, and other uninsured casualty damage to its property, including
transmission and distribution facilities. As permitted by the Mississippi PSC and the FERC, Mississippi Power accrues for the
cost of such damage through an annual expense accrual credited to regulatory liability accounts for the retail and wholesale
jurisdictions. The cost of repairing actual damage resulting from such events that individually exceed $50,000 is charged to the
reserve. Every three years the Mississippi PSC, the MPUS, and Mississippi Power will agree on SRR revenue level(s) for the
ensuing period, based on historical data, expected exposure, type and amount of insurance coverage, excluding insurance cost,
and any other relevant information. The accrual amount and the reserve balance are determined based on the SRR revenue
level(s). If a significant change in circumstances occurs, then the SRR revenue level can be adjusted more frequently if
Mississippi Power and the MPUS or the Mississippi PSC deem the change appropriate. The property damage reserve accrual will
be the difference between the approved SRR revenues and the SRR revenue requirement, excluding any accrual to the reserve. In
addition, SRR allows Mississippi Power to set up a regulatory asset, pending review, if the allowable actual retail property
damage costs exceed the amount in the retail property damage reserve. Mississippi Power made retail accruals of $1 million, $3
million, and $4 million for 2018, 2017, and 2016, respectively. Mississippi Power also accrued $0.3 million annually in 2018,
2017, and 2016 for the wholesale jurisdiction. As of December 31, 2018, the property damage reserve balances were $55 million
and $1 million for retail and wholesale, respectively.
Based on Mississippi Power's annual SRR rate filings, the SRR rate was zero for all years presented and Mississippi Power
accrued $2 million, $4 million, and $3 million to the property damage reserve in 2018, 2017, and 2016, respectively. The SRR
rate filings were suspended by the Mississippi PSC for review for a period not to exceed 120 days from their respective filing
dates, after which the filings became effective.
In January 2017, a tornado caused extensive damage to Mississippi Power's transmission and distribution infrastructure. The cost
of storm damage repairs was approximately $9 million. A portion of these costs was charged to the retail property damage reserve
and addressed in the 2018 SRR rate filing.
Kemper County Energy Facility
Overview
The Kemper County energy facility was designed to utilize IGCC technology with an expected output capacity of 582 MWs and
to be fueled by locally mined lignite (an abundant, lower heating value coal) from a mine owned by Mississippi Power and
situated adjacent to the Kemper County energy facility. The mine, operated by North American Coal Corporation, started
commercial operation in 2013. In connection with the Kemper County energy facility construction, Mississippi Power constructed
approximately 61 miles of CO2 pipeline infrastructure for the transport of captured CO2 for use in enhanced oil recovery.
Schedule and Cost Estimate
In 2012, the Mississippi PSC issued an order (2012 MPSC CPCN Order), confirming the CPCN originally approved by the
Mississippi PSC in 2010 authorizing the acquisition, construction, and operation of the Kemper County energy facility. The
certificated cost estimate of the Kemper County energy facility included in the 2012 MPSC CPCN Order was $2.4 billion, net of
approximately $0.57 billion for the cost of the lignite mine and equipment, the cost of the CO2 pipeline facilities, AFUDC, and
certain general exceptions (Cost Cap Exceptions). The 2012 MPSC CPCN Order approved a construction cost cap of up to $2.88
billion, with recovery of prudently-incurred costs subject to approval by the Mississippi PSC. The Kemper County energy facility
was originally projected to be placed in service in May 2014. Mississippi Power placed the combined cycle and the associated
common facilities portion of the Kemper County energy facility in service in August 2014. The combined cycle and associated
common facilities portions of the Kemper County energy facility were dedicated as Plant Ratcliffe on April 27, 2018.
On June 21, 2017, the Mississippi PSC stated its intent to issue an order, which occurred on July 6, 2017, directing Mississippi
Power to pursue a settlement under which the Kemper County energy facility would be operated as a natural gas plant, rather than
an IGCC plant, and address all issues associated with the Kemper County energy facility. The order established a new docket for
the purpose of pursuing a global settlement of the related costs (Kemper Settlement Docket). On June 28, 2017, Mississippi
82
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Power notified the Mississippi PSC that it would begin a process to suspend operations and start-up activities on the gasifier
portion of the Kemper County energy facility, given the uncertainty as to its future.
At the time of project suspension in June 2017, the total cost estimate for the Kemper County energy facility was approximately
$7.38 billion, including approximately $5.95 billion of costs subject to the construction cost cap, and was net of the $137 million
in additional grants from the DOE received in April 2016. In the aggregate, Mississippi Power had recorded charges to income of
$3.07 billion ($1.89 billion after tax) as a result of changes in the cost estimate above the cost cap for the Kemper IGCC through
May 31, 2017.
Given the Mississippi PSC's stated intent regarding no further rate increase for the Kemper County energy facility and the
subsequent suspension, cost recovery of the gasifier portions became no longer probable; therefore, Mississippi Power recorded
an additional charge to income in June 2017 of $2.8 billion ($2.0 billion after tax), which included estimated costs associated with
the gasification portions of the plant and lignite mine. During the third and fourth quarters of 2017, Mississippi Power recorded
charges to income of $242 million ($206 million after tax), including $164 million for ongoing project costs, estimated mine and
gasifier-related costs, and certain termination costs during the suspension period prior to conclusion of the Kemper Settlement
Docket, as well as the charge associated with the Kemper Settlement Agreement discussed below.
In 2018, Mississippi Power recorded pre-tax charges to income of $37 million ($27 million after tax), primarily resulting from the
abandonment and related closure activities and ongoing period costs, net of sales proceeds, for the mine and gasifier-related assets
at the Kemper County energy facility. In addition, Mississippi Power recorded a credit to earnings of $95 million in the fourth
quarter 2018 primarily resulting from the reduction of a valuation allowance for a state income tax NOL carryforward associated
with the Kemper County energy facility. Additional closure costs for the mine and gasifier-related assets, currently estimated at up
to $10 million pre-tax (excluding salvage, net of dismantlement costs), may be incurred through the first half of 2020. In addition,
period costs, including, but not limited to, costs for compliance and safety, ARO accretion, and property taxes for the mine and
gasifier-related assets, are estimated to total $11 million in 2019 and $2 million to $4 million annually in 2020 through 2023.
Mississippi Power is currently evaluating its options regarding the final disposition of the CO2 pipeline, including removal of the
pipeline. This evaluation is expected to be complete later in 2019. If Mississippi Power ultimately decides to remove the CO2
pipeline, the cost of removal would have a material impact on Mississippi Power's financial statements and could have a material
impact on Southern Company's financial statements. The ultimate outcome of these matters cannot be determined at this time.
See Note 10 for additional information.
Rate Recovery
Kemper Settlement Agreement
In 2015, the Mississippi PSC issued an order (In-Service Asset Rate Order) regarding the Kemper County energy facility assets
that were commercially operational and providing service to customers (the transmission facilities, combined cycle, natural gas
pipeline, and water pipeline) and other related costs. The In-Service Asset Rate Order provided for retail rate recovery of an
annual revenue requirement of approximately $126 million which went into effect on December 17, 2015.
On February 6, 2018, the Mississippi PSC voted to approve a settlement agreement related to cost recovery for the Kemper
County energy facility among Mississippi Power, the MPUS, and certain intervenors (Kemper Settlement Agreement), which
resolved all cost recovery issues, modified the CPCN to limit the Kemper County energy facility to natural gas combined cycle
operation, and provided for an annual revenue requirement of approximately $99.3 million for costs related to the Kemper County
energy facility, which included the impact of the Tax Reform Legislation. The revenue requirement is based on (i) a fixed ROE
for 2018 of 8.6% excluding any performance adjustment, (ii) a ROE for 2019 calculated in accordance with PEP, excluding the
performance adjustment, (iii) for future years, a performance-based ROE calculated pursuant to PEP, and (iv) amortization
periods for the related regulatory assets and liabilities of eight years and six years, respectively. The revenue requirement also
reflects a disallowance related to a portion of Mississippi Power's investment in the Kemper County energy facility requested for
inclusion in rate base, which was recorded in the fourth quarter 2017 as an additional charge to income of approximately $78
million ($85 million net of accumulated depreciation of $7 million) pre-tax ($48 million after tax).
Under the Kemper Settlement Agreement, retail customer rates reflect a reduction of approximately $26.8 million annually,
effective with the first billing cycle of April 2018, and include no recovery for costs associated with the gasifier portion of the
Kemper County energy facility in 2018 or at any future date.
Reserve Margin Plan
On August 6, 2018, Mississippi Power filed its proposed Reserve Margin Plan (RMP), as required by the Mississippi PSC's order
in the Kemper Settlement Docket. Under the RMP, Mississippi Power proposed alternatives that would reduce its reserve margin,
83
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
with the most economic of the alternatives being the two-year and seven-year acceleration of the retirement of Plant Watson Units
4 and 5, respectively, to the first quarter 2022 and the four-year acceleration of the retirement of Plant Greene County Units 1 and
2 to the third quarter 2021 and the third quarter 2022, respectively, in order to lower or avoid operating costs. The Plant Greene
County unit retirements would require the completion by Alabama Power of proposed transmission and system reliability
improvements, as well as agreement by Alabama Power. The RMP filing also states that, in the event the Mississippi PSC
ultimately approves an alternative that includes an accelerated retirement, Mississippi Power would require authorization to defer
in a regulatory asset for future recovery the remaining net book value of the units at the time of retirement. A decision by the
Mississippi PSC that does not include recovery of the remaining book value of any generating units retired could have a material
impact on Mississippi Power's and Southern Company's financial statements. The ultimate outcome of this matter cannot be
determined at this time.
Lignite Mine and CO2 Pipeline Facilities
Mississippi Power owns the lignite mine and equipment and mineral reserves located around the Kemper County energy facility
site. The mine started commercial operation in June 2013.
In 2010, Mississippi Power executed a 40-year management fee contract with Liberty Fuels Company, LLC (Liberty Fuels), a
wholly-owned subsidiary of The North American Coal Corporation, which developed, constructed, and is responsible for the
mining operations through the end of the mine reclamation. As the mining permit holder, Liberty Fuels has a legal obligation to
perform mine reclamation and Mississippi Power has a contractual obligation to fund all reclamation activities. As a result of the
abandonment of the Kemper IGCC, final mine reclamation began in 2018 and is expected to be substantially completed in 2020,
with monitoring expected to continue through 2027. See Note 6 and Note 7 under "Mississippi Power" for additional information.
In addition, Mississippi Power constructed the CO2 pipeline for the planned transport of captured CO2 for use in enhanced oil
recovery and entered into an agreement with Denbury Onshore (Denbury) to purchase the captured CO2. The agreement with
Denbury was terminated in December 2018 and did not have a material impact on Southern Company's or Mississippi Power's
results of operations. Mississippi Power is currently evaluating its options regarding the final disposition of the CO2 pipeline,
including removal of the pipeline. This evaluation is expected to be complete later in 2019. If Mississippi Power ultimately
decides to remove the CO2 pipeline, the cost of removal would have a material impact on Mississippi Power's financial statements
and could have a material impact on Southern Company's financial statements. The ultimate outcome of this matter cannot be
determined at this time.
Government Grants
In 2010, the DOE, through a cooperative agreement with SCS, agreed to fund $270 million of the Kemper County energy facility
through the grants awarded to the project by the DOE under the Clean Coal Power Initiative Round 2. Through December 31,
2018, Mississippi Power received total DOE grants of $387 million, of which $382 million reduced the construction costs of the
Kemper County energy facility and $5 million reimbursed Mississippi Power for expenses associated with DOE reporting. On
December 12, 2018, Mississippi Power filed with the DOE its request for property closeout certification under the contract related
to the grants received. Mississippi Power and the DOE are currently in discussions regarding the requested closeout and property
disposition, which may require payment to the DOE for a portion of certain property that is to be retained by Mississippi Power.
The ultimate outcome of this matter cannot be determined at this time; however, it could have a material impact on Mississippi
Power's financial statements and a significant impact on Southern Company's financial statements.

cost recovery clause. See "Rate Proceedings" herein for additional information regarding customer refunds resulting from the Tax Reform Legislation.
(i) Includes excess deferred income tax liabilities not subject to normalization as a result of the Tax Reform Legislation, the recovery and amortization of which
is expected to be determined by the applicable state regulatory agencies in future rate proceedings. See "Rate Proceedings" herein and Note 10 for additional
details.
Infrastructure Replacement Programs and Capital Projects
In addition to capital expenditures recovered through base rates by each of the natural gas distribution utilities, Nicor Gas and
Virginia Natural Gas have separate rate riders that provide timely recovery of capital expenditures for specific infrastructure
replacement programs. Descriptions of the infrastructure replacement programs and capital projects at the natural gas distribution
utilities follow:
Nicor Gas
In 2013, Illinois enacted legislation that allows Nicor Gas to provide more widespread safety and reliability enhancements to its
distribution system. The legislation stipulates that rate increases to customers as a result of any infrastructure investments shall
not exceed a cumulative annual average of 4.0% or, in any given year, 5.5% of base rate revenues. In 2014, the Illinois
Commission approved the nine-year regulatory infrastructure program, Investing in Illinois, subject to annual review. In
conjunction with the base rate case order issued by the Illinois Commission on January 31, 2018, Nicor Gas is recovering
program costs incurred prior to December 31, 2017 through base rates. Nicor Gas has requested that the program costs incurred
85
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
subsequent to December 31, 2017, which are currently being recovered through a separate rider, be addressed in the base rate case
filed November 9, 2018. See "Rate Proceedings" herein for additional information.
Virginia Natural Gas
In 2012, the Virginia Commission approved the Steps to Advance Virginia's Energy (SAVE) program, an accelerated
infrastructure replacement program, to be completed over a five-year period. In 2016, the Virginia Commission approved an
extension to the SAVE program for Virginia Natural Gas to replace more than 200 miles of aging pipeline infrastructure and
invest up to $30 million in 2016 and up to $35 million annually through 2021.
The SAVE program is subject to annual review by the Virginia Commission. In conjunction with the base rate case order issued
by the Virginia Commission in December 2017, Virginia Natural Gas is recovering program costs incurred prior to September 1,
2017 through base rates. Program costs incurred subsequent to September 1, 2017 are currently recovered through a separate rider
and are subject to future base rate case proceedings.
Atlanta Gas Light
GRAM
In February 2017, the Georgia PSC approved GRAM and a $20 million increase in annual base rate revenues for Atlanta Gas
Light, effective March 1, 2017. GRAM adjusts base rates annually, up or down, using an earnings band based on the previously
approved ROE of 10.75% and does not collect revenue through special riders and surcharges. Atlanta Gas Light adjusts rates up to
the lower end of the band of 10.55% and adjusts rates down to the higher end of the band of 10.95%. Various infrastructure
programs previously authorized by the Georgia PSC under Atlanta Gas Light's STRIDE program including the Integrated Vintage
Plastic Replacement Program to replace aging plastic pipe and the Integrated System Reinforcement Program to upgrade Atlanta
Gas Light's distribution system and LNG facilities in Georgia continue under GRAM and the recovery of and return on the
infrastructure program investments are included in annual base rate adjustments. The Georgia PSC reviews Atlanta Gas Light's
performance annually under GRAM. See Rate Proceedings" herein for additional information.
Pursuant to the GRAM approval, Atlanta Gas Light and the staff of the Georgia PSC agreed to a variation of the Integrated
Customer Growth Program to extend pipeline facilities to serve customers in areas without pipeline access and create new
economic development opportunities in Georgia, which was formerly part of the STRIDE program. As a result, a new tariff was
created, effective October 10, 2017, to provide up to $15 million annually for Atlanta Gas Light to commit to strategic economic
development projects. Projects under this tariff must be approved by the Georgia PSC.
The orders for the STRIDE program provide for recovery of all prudent costs incurred in the performance of the program. Atlanta
Gas Light will recover from end-use customers, through billings to Marketers, the costs related to the program, net of any related
cost savings. The regulatory asset represents incurred program costs that will be collected through GRAM. The future expected
costs to be recovered through rates related to allowed, but not incurred, costs are recognized in an unrecognized ratemaking
amount that is not reflected on the balance sheets. This allowed cost is primarily the equity return on the capital investment under
the program. See "Unrecognized Ratemaking Amounts" herein for additional information.
Atlanta Gas Light capitalizes and depreciates the capital expenditure costs incurred from the STRIDE programs over the life of
the assets. Operations and maintenance costs are expensed as incurred. Recoveries, which are recorded as revenue, are based on a
formula that allows Atlanta Gas Light to recover operations and maintenance costs in excess of those included in its current base
rates, depreciation, and an allowed rate of return on capital expenditures. However, Atlanta Gas Light is allowed the recovery of
carrying costs on the under recovered balance resulting from the timing difference.
PRP
In 2015, Atlanta Gas Light began recovering incremental PRP surcharge amounts through three phased-in increases in addition to
its already existing PRP surcharge amount, which was established to address recovery of the under recovered PRP balance of
$144 million and the estimated amounts to be earned under the program through 2025. The unrecovered balance is the result of
the continued revenue requirement earned under the program offset by the existing and incremental PRP surcharges. The under
recovered balance at December 31, 2018 was $171 million, including $95 million of unrecognized equity return. The PRP
surcharge will remain in effect until the earlier of the full recovery of the under recovered amount or December 31, 2025. See
"Rate Proceedings" and "Unrecognized Ratemaking Amounts" herein for additional information.
One of the capital projects under the PRP experienced construction issues and Atlanta Gas Light was required to complete
mitigation work prior to placing it in service. These mitigation costs were included in base rates in 2018. In 2017, Atlanta Gas
Light recovered $20 million from the settlement of contractor litigation claims and recovered an additional $7 million from the
86
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
final settlement of contractor litigation claims during the first quarter 2018. Mitigation costs recovered through the legal process
are retained by Atlanta Gas Light.
Natural Gas Cost Recovery
With the exception of Atlanta Gas Light, the natural gas distribution utilities are authorized by the relevant regulatory agencies in
the states in which they serve to use natural gas cost recovery mechanisms that adjust rates to reflect changes in the wholesale
cost of natural gas and ensure recovery of all costs prudently incurred in purchasing natural gas for customers. Natural gas cost
recovery revenues are adjusted for differences in actual recoverable natural gas costs and amounts billed in current regulated
rates. Changes in the billing factor will not have a significant effect on Southern Company's or Southern Company Gas' revenues
or net income, but will affect cash flows.
Rate Proceedings
Nicor Gas
On January 31, 2018, the Illinois Commission approved a $137 million increase in annual base rate revenues, including $93
million related to the recovery of investments under the Investing in Illinois program, effective February 8, 2018, based on a ROE
of 9.8%.
On April 19, 2018, the Illinois Commission approved Nicor Gas' variable income tax adjustment rider. This rider provides for
refund or recovery of changes in income tax expense that result from income tax rates that differ from those used in Nicor Gas'
last rate case. Customer refunds, via bill credits, related to the impacts of the Tax Reform Legislation from January 25, 2018
through May 4, 2018 began on July 1, 2018 and are expected to conclude in the second quarter 2019.
On May 2, 2018, the Illinois Commission approved Nicor Gas' rehearing request for revised base rates to incorporate the
reduction in the federal income tax rate as a result of the Tax Reform Legislation. The resulting decrease of approximately $44
million in annual base rate revenues became effective May 5, 2018. Nicor Gas' previously-authorized capital structure and ROE
of 9.80% were not addressed in the rehearing and remain unchanged.
On November 9, 2018, Nicor Gas filed a general base rate case with the Illinois Commission requesting a $230 million increase in
annual base rate revenues. The requested increase is based on a projected test year for the 12-month period ending September 30,
2020, a ROE of 10.6%, and an increase in the equity ratio from 52.0% to 54.0% to address the negative cash flow and credit
metric impacts of the Tax Reform Legislation. The Illinois Commission is expected to rule on the requested increase within the
11-month statutory time limit, after which rate adjustments will be effective. The ultimate outcome of this matter cannot be
determined at this time.
Atlanta Gas Light
On February 23, 2018, Atlanta Gas Light revised its annual base rate filing to reflect the impacts of the Tax Reform Legislation
and requested a $16 million rate reduction in 2018. On May 15, 2018, the Georgia PSC approved a stipulation for Atlanta Gas
Light's annual base rates to remain at the 2017 level for 2018 and 2019, with customer credits of $8 million in each of July 2018
and October 2018 to reflect the impacts of the Tax Reform Legislation. The Georgia PSC maintained Atlanta Gas Light's
previously authorized earnings band based on a ROE between 10.55% and 10.95% and increased the allowed equity ratio by 4%
to an equity ratio of 55% to address the negative cash flow and credit metric impacts of the Tax Reform Legislation. Additionally,
Atlanta Gas Light is required to file a traditional base rate case on or before June 1, 2019 for rates effective January 1, 2020.
Atlanta Gas Light's recovery of the previously unrecovered PRP revenue through 2014, as well as the mitigation costs associated
with the PRP that were not previously included in its rates, were included in GRAM. In connection with the GRAM approval, the
last monthly PRP surcharge increase became effective March 1, 2017.
Virginia Natural Gas
On December 21, 2017, the Virginia Commission approved a settlement for a $34 million increase in annual base rate revenues,
effective September 1, 2017, including $13 million related to the recovery of investments under the SAVE program. See
"Regulatory Infrastructure Programs" herein for additional information. An authorized ROE range of 9.0% to 10.0% with a
midpoint of 9.5% will be used to determine the revenue requirement in any filing, other than for a change in base rates.
On December 17, 2018, the Virginia Commission approved Virginia Natural Gas' annual information form filing, which reduced
annual base rates by $14 million effective January 1, 2019 due to lower tax expense as a result of the lower corporate income tax
rate and the impact of the flowback of excess deferred income taxes. This approval also requires Virginia Natural Gas to issue
87

customer refunds, via bill credits, for the entire $14 million which was deferred as a regulatory liability, current, on the balance
sheet at December 31, 2018. These customer refunds are expected to be completed in the first quarter 2019.
energySMART
The Illinois Commission approved Nicor Gas' energySMART program, which includes energy efficiency program offerings and
therm reduction goals. Through December 31, 2017, Nicor Gas spent $107 million of the initial authorized expenditure of $113
million. A new program began on January 1, 2018, with an additional authorized expenditure of $160 million through 2021.
Through December 31, 2018, Nicor Gas had spent $29 million.
Unrecognized Ratemaking Amounts
The following table illustrates Southern Company Gas' authorized ratemaking amounts that are not recognized on its balance
sheets. These amounts are primarily composed of an allowed equity rate of return on assets associated with certain regulatory
infrastructure programs. These amounts will be recognized as revenues in Southern Company Gas' financial statements in the
periods they are billable to customers, the majority of which will be recovered by 2025.

On May 10, 2018, AMEA and Cooperative Energy filed with the FERC a complaint against SCS and the traditional electric
operating companies claiming that the current 11.25% base ROE used in calculating the annual transmission revenue
requirements of the traditional electric operating companies' open access transmission tariff is unjust and unreasonable as
measured by the applicable FERC standards. The complaint requested that the base ROE be set no higher than 8.65% and that the
FERC order refunds for the difference in revenue requirements that results from applying a just and reasonable ROE established
in this proceeding upon determining the current ROE is unjust and unreasonable. On June 18, 2018, SCS and the traditional
electric operating companies filed their response challenging the adequacy of the showing presented by the complainants and
offering support for the current ROE. On September 6, 2018, the FERC issued an order establishing a refund effective date of
May 10, 2018 in the event a refund is due and initiating an investigation and settlement procedures regarding the current base
ROE. Through December 31, 2018, the estimated maximum potential refund is not expected to be material to Southern
Company's or the traditional electric operating companies' results of operations or cash flows. The ultimate outcome of this matter
cannot be determined at this time.
Mississippi Power
Municipal and Rural Associations Tariff
Mississippi Power provides wholesale electric service to Cooperative Energy, East Mississippi Electric Power Association, and
the City of Collins, all located in southeastern Mississippi, under a long-term cost-based, FERC-regulated MRA tariff.
In 2016, Mississippi Power reached a settlement agreement with its wholesale customers, which was subsequently approved by
the FERC, for an increase in wholesale base revenues under the MRA cost-based electric tariff, primarily as a result of placing
scrubbers for Plant Daniel Units 1 and 2 in service in 2015. The settlement agreement became effective for services rendered
beginning May 1, 2016, resulting in an estimated annual revenue increase of $7 million under the MRA cost-based electric tariff.
Additionally, under the settlement agreement, the tariff customers agreed to similar regulatory treatment for MRA tariff
ratemaking as the treatment approved for retail ratemaking under the In-Service Asset Rate Order. This regulatory treatment
primarily included (i) recovery of the operational Kemper County energy facility assets providing service to customers and other
related costs, (ii) amortization of the Kemper County energy facility-related regulatory assets included in rates under the
settlement agreement over the 36 months ending April 30, 2019, (iii) Kemper County energy facility-related expenses included in
rates under the settlement agreement no longer being deferred and charged to expense, and (iv) removing all of the Kemper

$22 million through the suspension of Kemper IGCC start-up activities.
Mississippi Power expects to reach a subsequent settlement agreement with its wholesale customers and will make a filing with
the FERC during the first quarter 2019. The settlement agreement is intended to be consistent with the Kemper Settlement
Agreement, including the impact of the Tax Reform Legislation. The ultimate outcome of this matter cannot be determined at this
time.
In September 2017, Mississippi Power and Cooperative Energy executed a Shared Service Agreement (SSA), as part of the MRA
tariff, under which Mississippi Power and Cooperative Energy will share in providing electricity to all Cooperative Energy
delivery points, in lieu of the current arrangement under which each delivery point is specifically assigned to either entity. The
SSA accepted by the FERC in October 2017 became effective on January 1, 2018 and may be cancelled by Cooperative Energy
with 10 years notice after December 31, 2020. The SSA provides Cooperative Energy the option to decrease its use of Mississippi
Power's generation services under the MRA tariff, subject to annual and cumulative caps and a one-year notice requirement. In the
event Cooperative Energy elects to reduce these services, the related reduction in Mississippi Power's revenues is not expected to
be significant through 2020.
Fuel Cost Recovery
Mississippi Power has a wholesale MRA and a Market Based (MB) fuel cost recovery factor. Effective with the first billing cycle
for January 2018, fuel rates increased $11 million annually for wholesale MRA customers and $1 million annually for wholesale
MB customers. Effective January 1, 2019, the wholesale MRA fuel rate decreased $16 million annually and the wholesale MB
fuel rate decreased by an immaterial amount. At December 31, 2018, over recovered wholesale MRA fuel costs included in other
regulatory liabilities, current on the balance sheet were approximately $6 million compared to an immaterial amount at December
31, 2017. Under recovered wholesale MB fuel costs included in the balance sheets were immaterial at December 31, 2018 and
2017.
Mississippi Power's operating revenues are adjusted for differences in actual recoverable fuel cost and amounts billed in
accordance with the currently approved cost recovery rate. Accordingly, changes in the billing factor should have no significant
effect on Mississippi Power's revenues or net income, but will affect cash flow.
Southern Company Gas
At December 31, 2018, Southern Company Gas was involved in two gas pipeline construction projects. These projects, along with
Southern Company Gas' existing pipelines, are intended to provide diverse sources of natural gas supplies to customers, resolve
current and long-term supply planning for new capacity, enhance system reliability, and generate economic development in the
areas served.
On January 19, 2018, the PennEast Pipeline received FERC approval. Work continues with state and federal agencies to obtain
the required permits to begin construction. Any material delays may impact forecasted capital expenditures and the expected in-
service date.
In October 2017, the Atlantic Coast Pipeline received FERC approval. This joint venture has experienced challenges to its permits
since construction began in 2018. During the third and fourth quarters 2018, a FERC stop work order, together with delays in
obtaining permits necessary for construction and construction delays due to judicial actions, impacted the cost and schedule for
the project. As a result, total project cost estimates have increased from between $6.0 billion and $6.5 billion to between $7.0
billion and $7.8 billion, excluding financing costs. Southern Company Gas' share of the total project costs is 5% and Southern
Company Gas' investment at December 31, 2018 totaled $83 million. The operator of the joint venture currently expects to
achieve a late 2020 in-service date for at least key segments of the Atlantic Coast Pipeline, while the remainder may extend into
early 2021. Southern Company Gas has evaluated the recoverability of its investment and determined there was no impairment as
of December 31, 2018. Abnormal weather, work delays (including due to judicial or regulatory action), and other conditions may
result in additional cost or schedule modifications, which could result in an impairment of Southern Company Gas' investment
and could have a material impact on Southern Company's and Southern Company Gas' financial statements.
The ultimate outcome of these matters cannot be determined at this time. See Notes 7 and 9 under "Southern Company Gas –
Equity Method Investments" and "Guarantees," respectively, for additional information on these pipeline projects.

3. CONTINGENCIES
General Litigation Matters
Each registrant is subject to certain claims and legal actions arising in the ordinary course of business. In addition, the business
activities of Southern Company's subsidiaries are subject to extensive governmental regulation related to public health and the
environment, such as laws and regulations governing air, water, land, and protection of other natural resources. Litigation over
environmental issues and claims of various types, including property damage, personal injury, common law nuisance, and citizen
enforcement of environmental laws and regulations has occurred throughout the U.S. This litigation has included claims for
damages alleged to have been caused by CO2 and other emissions, CCR, and alleged exposure to hazardous materials, and/or
requests for injunctive relief in connection with such matters.
The ultimate outcome of such pending or potential litigation against each registrant and any subsidiaries cannot be predicted at
this time; however, for current proceedings not specifically reported herein, management does not anticipate that the ultimate
liabilities, if any, arising from such current proceedings would have a material effect on such registrant's financial statements.
Southern Company
In January 2017, a putative securities class action complaint was filed against Southern Company, certain of its officers, and
certain former Mississippi Power officers in the U.S. District Court for the Northern District of Georgia, Atlanta Division, by
Monroe County Employees' Retirement System on behalf of all persons who purchased shares of Southern Company's common
stock between April 25, 2012 and October 29, 2013. The complaint alleges that Southern Company, certain of its officers, and
certain former Mississippi Power officers made materially false and misleading statements regarding the Kemper County energy
facility in violation of certain provisions under the Securities Exchange Act of 1934, as amended. The complaint seeks, among
other things, compensatory damages and litigation costs and attorneys' fees. In June 2017, the plaintiffs filed an amended
complaint that provided additional detail about their claims, increased the purported class period by one day, and added certain
other former Mississippi Power officers as defendants. In July 2017, the defendants filed a motion to dismiss the plaintiffs'
amended complaint with prejudice, to which the plaintiffs filed an opposition in September 2017. On March 29, 2018, the U.S.
District Court for the Northern District of Georgia, Atlanta Division, issued an order granting, in part, the defendants' motion to
dismiss. The court dismissed certain claims against certain officers of Southern Company and Mississippi Power and dismissed
the allegations related to a number of the statements that plaintiffs challenged as being false or misleading. On April 26, 2018, the
defendants filed a motion for reconsideration of the court's order, seeking dismissal of the remaining claims in the lawsuit. On
August 10, 2018, the court denied the motion for reconsideration and denied a motion to certify the issue for interlocutory appeal.
In February 2017, Jean Vineyard filed a shareholder derivative lawsuit and, in May 2017, Judy Mesirov filed a shareholder
derivative lawsuit, each in the U.S. District Court for the Northern District of Georgia. Each of these lawsuits names as defendants
Southern Company, certain of its directors, certain of its officers, and certain former Mississippi Power officers. In August 2017,
these two shareholder derivative lawsuits were consolidated in the U.S. District Court for the Northern District of Georgia. The
complaints allege that the defendants caused Southern Company to make false or misleading statements regarding the Kemper
County energy facility cost and schedule. Further, the complaints allege that the defendants were unjustly enriched and caused the
waste of corporate assets and also allege that the individual defendants violated their fiduciary duties. Each plaintiff seeks to
recover, on behalf of Southern Company, unspecified actual damages and, on each plaintiff's own behalf, attorneys' fees and costs
in bringing the lawsuit. Each plaintiff also seeks certain changes to Southern Company's corporate governance and internal
processes. On April 25, 2018, the court entered an order staying this lawsuit until 30 days after the resolution of any dispositive
motions or any settlement, whichever is earlier, in the putative securities class action.
In May 2017, Helen E. Piper Survivor's Trust filed a shareholder derivative lawsuit in the Superior Court of Gwinnett County,
State of Georgia that names as defendants Southern Company, certain of its directors, certain of its officers, and certain former
Mississippi Power officers. The complaint alleges that the individual defendants, among other things, breached their fiduciary
duties in connection with schedule delays and cost overruns associated with the construction of the Kemper County energy
facility. The complaint further alleges that the individual defendants authorized or failed to correct false and misleading
statements regarding the Kemper County energy facility schedule and cost and failed to implement necessary internal controls to
prevent harm to Southern Company. The plaintiff seeks to recover, on behalf of Southern Company, unspecified actual damages
and disgorgement of profits and, on its behalf, attorneys' fees and costs in bringing the lawsuit. The plaintiff also seeks certain
unspecified changes to Southern Company's corporate governance and internal processes. On May 4, 2018, the court entered an
order staying this lawsuit until 30 days after the resolution of any dispositive motions or any settlement, whichever is earlier, in
the putative securities class action.

NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Southern Company believes these legal challenges have no merit; however, an adverse outcome in any of these proceedings could
have an impact on Southern Company's results of operations, financial condition, and liquidity. Southern Company will
vigorously defend itself in these matters, the ultimate outcome of which cannot be determined at this time.
Alabama Power
On March 2, 2018, the Alabama Department of Environmental Management (ADEM) issued proposed administrative orders
assessing a penalty of $1.25 million to Alabama Power for unpermitted discharge of fluids and/or pollutants to groundwater at
five electric generating plants. The orders were finalized and Alabama Power paid the penalty on September 27, 2018. This matter
is now concluded.
Georgia Power
In 2011, plaintiffs filed a putative class action against Georgia Power in the Superior Court of Fulton County, Georgia alleging
that Georgia Power's collection in rates of amounts for municipal franchise fees (which fees are paid to municipalities) exceeded
the amounts allowed in orders of the Georgia PSC and alleging certain state tort law claims. In 2016, the Georgia Court of
Appeals reversed the trial court's previous dismissal of the case and remanded the case to the trial court. Georgia Power filed a
petition for writ of certiorari with the Georgia Supreme Court, which was granted in August 2017. On June 18, 2018, the Georgia
Supreme Court affirmed the judgment of the Georgia Court of Appeals and remanded the case to the trial court for further
proceedings. Following a motion by Georgia Power, on February 13, 2019, the Superior Court of Fulton County entered an order
staying this lawsuit for 60 days and ordered the parties to submit petitions to the Georgia PSC within 20 days for a declaratory
ruling to address certain terms the court previously held were ambiguous as used in the Georgia PSC's orders. The order entered
by the Superior Court of Fulton County also conditionally certified the proposed class. Georgia Power believes the plaintiffs'
claims have no merit and will continue to vigorously defend itself in this matter. The amount of any possible losses cannot be
calculated at this time because, among other factors, it is unknown whether conditional class certification will be upheld and the
ultimate composition of any class; and whether any losses would be subject to recovery from any municipalities. The ultimate
outcome of this matter cannot be determined at this time.
Mississippi Power
In 2016, a complaint against Mississippi Power was filed in Harrison County Circuit Court (Circuit Court) by Biloxi Freezing &
Processing Inc., Gulfside Casino Partnership, and John Carlton Dean, which was amended and refiled to include, among other
things, Southern Company as a defendant. The individual plaintiff alleged that Mississippi Power and Southern Company violated
the Mississippi Unfair Trade Practices Act. All plaintiffs alleged that Mississippi Power and Southern Company concealed, falsely
represented, and failed to fully disclose important facts concerning the cost and schedule of the Kemper County energy facility
and that these alleged breaches unjustly enriched Mississippi Power and Southern Company. The plaintiffs sought unspecified
actual damages and punitive damages; asked the Circuit Court to appoint a receiver to oversee, operate, manage, and otherwise
control all affairs relating to the Kemper County energy facility; asked the Circuit Court to revoke any licenses or certificates
authorizing Mississippi Power or Southern Company to engage in any business related to the Kemper County energy facility in
Mississippi; and sought attorney's fees, costs, and interest. The plaintiffs also sought an injunction to prevent any Kemper County
energy facility costs from being charged to customers through electric rates. In June 2017, the Circuit Court ruled in favor of
motions by Southern Company and Mississippi Power and dismissed the case. In July 2017, the plaintiffs filed notice of an
appeal. On July 13, 2018, Mississippi Power and Southern Company reached a settlement agreement with the plaintiffs and the
plaintiffs' appeal was dismissed with prejudice. The settlement had no material impact on Southern Company's or Mississippi
Power's financial statements.
On May 18, 2018, Southern Company and Mississippi Power received a notice of dispute and arbitration demand filed by Martin
Product Sales, LLC (Martin) based on two agreements, both related to Kemper IGCC byproducts for which Mississippi Power
provided termination notices in September 2017. Martin alleges breach of contract, breach of good faith and fair dealing, fraud
and misrepresentation, and civil conspiracy and makes a claim for damages in the amount of approximately $143 million, as well
as additional unspecified damages, attorney's fees, costs, and interest. In the first quarter 2019, Mississippi Power and Southern
Company filed motions to dismiss. Southern Company and Mississippi Power believe this legal challenge has no merit; however,
an adverse outcome in this proceeding could have a material impact on Southern Company's and Mississippi Power's results of
operations, financial condition, and liquidity. Southern Company and Mississippi Power will vigorously defend themselves in this
matter, the ultimate outcome of which cannot be determined at this time.
On November 21, 2018, Ray C. Turnage and 10 other individual plaintiffs filed a putative class action complaint against
Mississippi Power and the three current members of the Mississippi PSC in the U.S. District Court for the Southern District of
Mississippi. Mississippi Power received Mississippi PSC approval in 2013 to charge a mirror CWIP rate premised upon including
91
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
in its rate base pre-construction and construction costs for the Kemper IGCC prior to placing the Kemper IGCC into service. The
Mississippi Supreme Court reversed that approval and ordered Mississippi Power to refund the amounts paid by customers under
the previously-approved mirror CWIP rate. The plaintiffs allege that the initial approval process, and the amount approved, were
improper. They also allege that Mississippi Power underpaid customers in the refund process because it applied the wrong interest
rate to the payments. The plaintiffs seek to recover, on behalf of themselves and their putative class, actual damages, punitive
damages, pre-judgment interest, post-judgment interest, attorney's fees, and costs. Mississippi Power believes this legal challenge
has no merit; however, an adverse outcome in this proceeding could have a material impact on Mississippi Power's results of
operations, financial condition, and liquidity. Mississippi Power will vigorously defend itself in this matter, the ultimate outcome
of which cannot be determined at this time.
Southern Power
Southern Power indirectly owns a 51% membership interest in RE Roserock LLC (Roserock), the owner of the Roserock facility
in Pecos County, Texas. Prior to the facility being placed in service in November 2016, certain solar panels were damaged during
installation by the construction contractor, McCarthy Building Companies, Inc. (McCarthy), and certain solar panels were
damaged by a hail event that also occurred during construction. In connection therewith, Southern Power is withholding payments
of approximately $26 million from the construction contractor, which has placed a lien on the Roserock facility for the same
amount. In May 2017, Roserock filed a lawsuit in the state district court in Pecos County, Texas, (State Court lawsuit) against XL
Insurance America, Inc. (XL) and North American Elite Insurance Company (North American Elite) seeking recovery from an
insurance policy for damages resulting from the hail storm and McCarthy's installation practices. On June 1, 2018, the court in
the State Court lawsuit granted Roserock's motion for partial summary judgment, finding that the insurers were in breach of
contract and in violation of the Texas Insurance Code for failing to pay any monies owed for the hail claim. In addition to the
State Court lawsuit, lawsuits were filed between Roserock and McCarthy, as well as other parties, and that litigation has been
consolidated in the U.S. District Court for the Western District of Texas. Southern Power intends to vigorously pursue and defend
these matters, the ultimate outcome of which cannot be determined at this time.
Southern Company Gas
Nicor Energy Services Company, doing business as Pivotal Home Solutions, formerly a wholly-owned subsidiary of Southern
Company Gas, was a defendant in a putative class action initially filed in 2017 in the state court in Indiana. The plaintiffs
purported to represent a class of the customers who purchased products from Nicor Energy Services Company and alleged that
the marketing, sale, and billing of the products violated the Indiana Consumer Fraud and Deceptive Business Practices Act,
constituting common law fraud and resulting in unjust enrichment of these entities. In 2018, Nicor Energy Services Company was
named in a second class action filed in the state court of Ohio asserting nearly identical allegations and legal claims. The plaintiffs
sought, on behalf of the classes they purported to represent, actual and punitive damages, interest costs, attorney fees, and
injunctive relief. To facilitate the sale of Pivotal Home Solutions, Southern Company Gas retained most of the financial
responsibility for these lawsuits following the completion of the sale. On June 12, 2018, the parties settled these claims and
Southern Company Gas recorded an $11 million charge, which is included in other operations and maintenance expenses for the
year ended December 31, 2018.
Southern Company Gas is involved in litigation relating to an incident that occurred in one of its prior service territories that
resulted in several deaths, injuries, and property damage. Southern Company Gas has resolved all claims for personal injuries or
death, but it is continuing to defend litigation seeking to recover alleged property damages. Southern Company Gas has insurance
that provides full coverage of the expected financial exposure in excess of $11 million per incident. During the successor period
ended December 31, 2016, Southern Company Gas recorded reserves for substantially all of its potential exposure from these
cases.
Environmental Remediation
The Southern Company system must comply with environmental laws and regulations governing the handling and disposal of
waste and releases of hazardous substances. Under these various laws and regulations, the Southern Company system could incur
substantial costs to clean up affected sites. The traditional electric operating companies and the natural gas distribution utilities
conduct studies to determine the extent of any required cleanup and have recognized the estimated costs to clean up known
impacted sites in the financial statements. A liability for environmental remediation costs is recognized only when a loss is
determined to be probable and reasonably estimable. The traditional electric operating companies and the natural gas distribution
utilities in Illinois and Georgia have each received authority from their respective state PSCs or other applicable state regulatory
agencies to recover approved environmental compliance costs through regulatory mechanisms. These regulatory mechanisms are
adjusted annually or as necessary within limits approved by the state PSCs or other applicable state regulatory agencies. At
92
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
December 31, 2018 and 2017, the environmental remediation liabilities of Alabama Power and Mississippi Power were
immaterial.
Georgia Power has been designated or identified as a potentially responsible party at sites governed by the Georgia Hazardous
Site Response Act and/or by the federal Comprehensive Environmental Response, Compensation, and Liability Act, and
assessment and potential cleanup of such sites is expected. In 2013, the Georgia PSC approved the 2013 ARP including the
recovery of approximately $2 million annually through the ECCR tariff. Georgia Power recognizes a liability for environmental
remediation costs only when it determines a loss is probable and reasonably estimable and reduces the reserve as expenditures are
incurred. Any difference between the liabilities accrued and costs recovered through rates is deferred as a regulatory asset or
liability. The annual recovery amount is expected to be adjusted as part of the Georgia Power 2019 Base Rate Case and further
adjusted in future regulatory proceedings.
Southern Company Gas is subject to environmental remediation liabilities associated with 40 former MGP sites in four different
states. Southern Company Gas' accrued environmental remediation liability at December 31, 2018 and 2017 was based on the
estimated cost of environmental investigation and remediation associated with known current and former MGP operating sites.
These environmental remediation expenditures are recoverable from customers through rate mechanisms approved by the
applicable state regulatory agencies of the natural gas distribution utilities, with the exception of one site representing $2 million
of the accrued remediation costs.
At December 31, 2018 and 2017, the environmental remediation liability and the balance of under recovered environmental
remediation costs were reflected in the balance sheets as follows:
December 31, 2018:
Environmental remediation liability:
Other current liabilities

1, 2018. See Note 15 under "Southern Company Gas" for more information regarding Southern Company Gas' sale of Elizabethtown Gas.
The ultimate outcome of these matters cannot be determined at this time; however, as a result of the regulatory treatment for
environmental remediation expenses described above, the final disposition of these matters is not expected to have a material
impact on the financial statements of Southern Company, Georgia Power, or Southern Company Gas.
Nuclear Fuel Disposal Costs
Acting through the DOE and pursuant to the Nuclear Waste Policy Act of 1982, the U.S. government entered into contracts with
Alabama Power and Georgia Power that require the DOE to dispose of spent nuclear fuel and high level radioactive waste
generated at Plants Farley, Hatch, and Vogtle Units 1 and 2 beginning no later than January 31, 1998. The DOE has yet to
commence the performance of its contractual and statutory obligation to dispose of spent nuclear fuel. Consequently, Alabama
Power and Georgia Power pursued and continue to pursue legal remedies against the U.S. government for its partial breach of
contract.
93
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
In 2014, Alabama Power and Georgia Power filed lawsuits against the U.S. government for the costs of continuing to store spent
nuclear fuel at Plants Farley, Hatch, and Vogtle Units 1 and 2 for the period from January 1, 2011 through December 31, 2013.
The damage period was subsequently extended to December 31, 2014. In October 2017, Alabama Power and Georgia Power filed
additional lawsuits against the U.S. government in the Court of Federal Claims for the costs of continuing to store spent nuclear
fuel at Plants Farley, Hatch, and Vogtle Units 1 and 2 for the period from January 1, 2015 through December 31, 2017. Damages
will continue to accumulate until the issue is resolved, the U.S. government disposes of Alabama Power's and Georgia Power's
spent nuclear fuel pursuant to its contractual obligations, or alternative storage is otherwise provided. No amounts have been
recognized in the financial statements as of December 31, 2018 for any potential recoveries from the pending lawsuits. The final
outcome of these matters cannot be determined at this time. However, Alabama Power and Georgia Power expect to credit any
recoveries back for the benefit of customers in accordance with direction from their respective PSC and, therefore, no material
impact on Southern Company's, Alabama Power's, or Georgia Power's net income is expected.
On-site dry spent fuel storage facilities are operational at all three plants and can be expanded to accommodate spent fuel through
the expected life of each plant.
Nuclear Insurance
Under the Price-Anderson Amendments Act (Act), Alabama Power and Georgia Power maintain agreements of indemnity with
the NRC that, together with private insurance, cover third-party liability arising from any nuclear incident occurring at the
companies' nuclear power plants. The Act provides funds up to $14.1 billion for public liability claims that could arise from a
single nuclear incident. Each nuclear plant is insured against this liability to a maximum of $450 million by American Nuclear
Insurers (ANI), with the remaining coverage provided by a mandatory program of deferred premiums that could be assessed, after
a nuclear incident, against all owners of commercial nuclear reactors. A company could be assessed up to $138 million per
incident for each licensed reactor it operates but not more than an aggregate of $20 million per incident to be paid in a calendar
year for each reactor. Such maximum assessment, excluding any applicable state premium taxes, for Alabama Power and Georgia
Power, based on its ownership and buyback interests in all licensed reactors, is $275 million and $267 million, respectively, per
incident, but not more than an aggregate of $41 million and $40 million, respectively, to be paid for each incident in any one year.
Both the maximum assessment per reactor and the maximum yearly assessment are adjusted for inflation at least every five years.
The next scheduled adjustment is due no later than September 10, 2023. See Note 5 under "Joint Ownership Agreements" for
additional information on joint ownership agreements.
Alabama Power and Georgia Power are members of Nuclear Electric Insurance Limited (NEIL), a mutual insurer established to
provide property damage insurance in an amount up to $1.5 billion for members' operating nuclear generating facilities.
Additionally, both companies have NEIL policies that currently provide decontamination, excess property insurance, and
premature decommissioning coverage up to $1.25 billion for nuclear losses and policies providing coverage up to $750 million
for non-nuclear losses in excess of the $1.5 billion primary coverage.
NEIL also covers the additional costs that would be incurred in obtaining replacement power during a prolonged accidental
outage at a member's nuclear plant. Members can purchase this coverage, subject to a deductible waiting period of up to 26
weeks, with a maximum per occurrence per unit limit of $490 million. After the deductible period, weekly indemnity payments
would be received until either the unit is operational or until the limit is exhausted. Alabama Power and Georgia Power each
purchase limits based on the projected full cost of replacement power, subject to ownership limitations, and have each elected a
12-week deductible waiting period for each nuclear plant.
A builders' risk property insurance policy has been purchased from NEIL for the construction of Plant Vogtle Units 3 and 4. This
policy provides the Vogtle Owners up to $2.75 billion for accidental property damage occurring during construction.
Under each of the NEIL policies, members are subject to assessments each year if losses exceed the accumulated funds available
to the insurer. The maximum annual assessments for Alabama Power and Georgia Power as of December 31, 2018 under the
NEIL policies would be $56 million and $85 million, respectively.
Claims resulting from terrorist acts are covered under both the ANI and NEIL policies (subject to normal policy limits). The
aggregate, however, that NEIL will pay for all claims resulting from terrorist acts in any 12-month period is $3.2 billion plus such
additional amounts NEIL can recover through reinsurance, indemnity, or other sources.
For all on-site property damage insurance policies for commercial nuclear power plants, the NRC requires that the proceeds of
such policies shall be dedicated first for the sole purpose of placing the reactor in a safe and stable condition after an accident.
Any remaining proceeds are to be applied next toward the costs of decontamination and debris removal operations ordered by the
NRC, and any further remaining proceeds are to be paid either to the applicable company or to its debt trustees as may be
appropriate under the policies and applicable trust indentures. In the event of a loss, the amount of insurance available might not
be adequate to cover property damage and other expenses incurred. Uninsured losses and other expenses, to the extent not
94
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
recovered from customers, would be borne by Alabama Power or Georgia Power, as applicable, and could have a material effect
on Southern Company's, Alabama Power's, and Georgia Power's financial condition and results of operations.
All retrospective assessments, whether generated for liability, property, or replacement power, may be subject to applicable state
premium taxes.
Other Matters
Mississippi Power
In 2013, Mississippi Power submitted a lost revenue claim under the Deep Horizon Economic and Property Damages Settlement
Agreement associated with the oil spill that occurred in the Gulf of Mexico in 2010. On May 14, 2018, Mississippi Power's claim
was settled. The settlement proceeds of $18 million, net of expenses and income tax, are included in Mississippi Power's earnings
for 2018. As of December 31, 2018, Mississippi Power had received half of the settlement proceeds.
Southern Company Gas
A wholly-owned subsidiary of Southern Company Gas owns and operates a natural gas storage facility consisting of two salt
dome caverns in Louisiana. Periodic integrity tests are required in accordance with rules of the Louisiana Department of Natural
Resources (DNR). In August 2017, in connection with an ongoing integrity project, updated seismic mapping indicated the
proximity of one of the caverns to the edge of the salt dome may be less than the required minimum and could result in Southern
Company Gas retiring the cavern early. At December 31, 2018, the facility's property, plant, and equipment had a net book value
of $109 million, of which the cavern itself represents approximately 20%. A potential early retirement of this cavern is dependent
upon several factors including compliance with an order from the Louisiana DNR detailing the requirements to place the cavern
back in service, which includes, among other things, obtaining core samples to determine the composition of the sheath
surrounding the edge of the salt dome.
The cavern continues to maintain its pressures and overall structural integrity. These events were considered in connection with
Southern Company Gas' annual long-lived asset impairment analysis, which determined there was no impairment as of
December 31, 2018. Any changes in results of monitoring activities, rates at which expiring capacity contracts are re-contracted,
timing of placing the cavern back in service, or Louisiana DNR requirements could trigger impairment. Further, early retirement
of the cavern could trigger impairment of other long-lived assets associated with the natural gas storage facility. The ultimate
outcome of this matter cannot be determined at this time, but could have a significant impact on Southern Company's or Southern
Company Gas' financial statements.

Remaining Performance Obligations
The traditional electric operating companies and Southern Power have long-term contracts with customers in which revenues are
recognized as performance obligations are satisfied over the contract term. These contracts primarily relate to PPAs whereby the
traditional electric operating companies and Southern Power provide electricity and generation capacity to a customer. The
revenue recognized for the delivery of electricity is variable; however, certain PPAs include a fixed payment for fixed generation
capacity over the term of the contract. Southern Company's unregulated distributed generation business also has partially satisfied
performance obligations related to certain fixed price contracts. Revenues from contracts with customers related to these
performance obligations remaining at December 31, 2018 are expected to be recognized as follows:

The cost of replacements of property, exclusive of minor items of property, is capitalized. The cost of maintenance, repairs, and
replacement of minor items of property is charged to other operations and maintenance expenses as incurred or performed with
the exception of nuclear refueling costs and certain maintenance costs including those described below.
In accordance with orders from their respective state PSCs, Alabama Power and Georgia Power defer nuclear outage operations
and maintenance expenses to a regulatory asset when the charges are incurred. Alabama Power amortizes the costs over a
subsequent 18-month period with Plant Farley's fall outage cost amortization beginning in January of the following year and
spring outage cost amortization beginning in July of the same year. Georgia Power amortizes its costs over each unit's operating
cycle, or 18 months for Plant Vogtle Units 1 and 2 and 24 months for Plant Hatch Units 1 and 2.

Depreciation and Amortization
The traditional electric operating companies' and Southern Company Gas' depreciation of the original cost of utility plant in
service is provided primarily by using composite straight-line rates. The approximate rates for 2018, 2017, and 2016 are as
follows:
Alabama Power
Georgia Power
Mississippi Power(*)
Southern Company Gas
2018
2017

2.8%
4.2%
2.8%
(*) Mississippi Power's decrease in 2017 is primarily the result of recording a loss on its lignite mine in June 2017.
Depreciation studies are conducted periodically to update the composite rates. These studies are filed with the respective state
PSC and/or other applicable state and federal regulatory agencies for the traditional electric operating companies and natural gas
distribution utilities. In 2016, Alabama Power submitted an updated depreciation study to the FERC and received authorization to
use the recommended rates beginning January 2017. The study was also provided to the Alabama PSC.
101
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Under the terms of the 2013 ARP, Georgia Power amortized approximately $14 million annually from 2014 through 2016 of its
remaining regulatory liability related to other cost of removal obligations.
Southern Company's 2017 depreciation includes $34 million of reductions in depreciation recognized by Gulf Power under the
terms of its 2013 rate case settlement agreement with the Florida PSC.
When property, plant, and equipment subject to composite depreciation is retired or otherwise disposed of in the normal course of
business, its original cost, together with the cost of removal, less salvage, is charged to accumulated depreciation. For other
property dispositions, the applicable cost and accumulated depreciation are removed from the balance sheet accounts, and a gain
or loss is recognized. Minor items of property included in the original cost of the asset are retired when the related property unit is
retired.
At December 31, 2018 and 2017, accumulated depreciation for utility plant in service totaled $30.3 billion and $30.8 billion,
respectively, for Southern Company and $4.3 billion and $4.5 billion, respectively, for Southern Company Gas.
Depreciation of the original cost of other plant in service is provided primarily on a straight-line basis over estimated useful lives,
which for Southern Company range up to 65 years and for Southern Company Gas range from five to 15 years for transportation
equipment, 40 to 60 years for storage facilities, and up to 65 years for other assets. At December 31, 2018 and 2017, accumulated
depreciation for other plant in service totaled $766 million and $673 million, respectively, for Southern Company and $129
million and $75 million, respectively, for Southern Company Gas.
Southern Power
Southern Power applies component depreciation, where depreciation is computed principally by the straight-line method over the
estimated useful life of the asset. Certain of Southern Power's generation assets related to natural gas-fired facilities are
depreciated on a units-of-production basis, using hours or starts, to better match outage and maintenance costs to the usage of, and
revenues from, these assets. The primary assets in Southern Power's property, plant, and equipment are generating facilities,
which generally have estimated useful lives as follows:
Southern Power Generating Facility
Natural gas
Biomass
Solar
Wind
Useful life
Up to 45 years
Up to 40 years
Up to 35 years
Up to 30 years
Southern Power reviews its estimated useful lives and salvage values on an ongoing basis. The results of these reviews could
result in changes which could have a material impact on Southern Power's net income in the near term.
When Southern Power's depreciable property, plant, and equipment is retired, or otherwise disposed of in the normal course of
business, the applicable cost and accumulated depreciation is removed and a gain or loss is recognized in the statements of
income.

pipeline system into northwest Georgia. Southern Company Gas also entered into an agreement to lease its 50% undivided ownership in the Dalton Pipeline
that became effective when it was placed in service in August 2017. Under the lease, Southern Company Gas will receive approximately $26 million annually
for an initial term of 25 years. The lessee is responsible for maintaining the pipeline during the lease term and for providing service to transportation
customers under its FERC-regulated tariff.
Georgia Power also owns 45.7% of Plant Vogtle Units 3 and 4, which are currently under construction and had a CWIP balance of
$4.5 billion at December 31, 2018. See Note 2 under "Georgia Power – Nuclear Construction" for additional information.
On December 4, 2018, Southern Power completed the sale of its 65% ownership interest in Plant Stanton Unit A, which Southern
Power previously jointly-owned with OUC, the FMPA, and the KUA, to NextEra Energy. See Note 15 under "Southern Power –
Sales of Natural Gas Plants" for additional information.
In conjunction with Southern Company's sale of Gulf Power, Mississippi Power and Gulf Power have committed to seek a
restructuring of their 50% undivided ownership interests in Plant Daniel such that each of them would, after the restructuring,
own 100% of a generating unit. On January 15, 2019, Gulf Power provided notice to Mississippi Power that Gulf Power will
retire its share of the generating capacity of Plant Daniel on January 15, 2024. Mississippi Power has the option to purchase Gulf
Power's ownership interest for $1 on January 15, 2024, provided that Mississippi Power exercises the option no later than 120
days prior to that date. Mississippi Power is assessing the potential operational and economic effects of Gulf Power's notice. The
ultimate outcome of these matters remains subject to completion of Mississippi Power's evaluations and applicable regulatory

The registrants' proportionate share of their jointly-owned facility operating expenses is included in the corresponding operating
expenses in the statements of income and each registrant is responsible for providing its own financing.
Assets Subject to Lien
On October 2, 2018, the Mississippi PSC approved executed agreements between Mississippi Power and its largest retail
customer, Chevron Products Company (Chevron), for Mississippi Power to continue providing retail service to the Chevron
refinery in Pascagoula, Mississippi through 2038. The agreements grant Chevron a security interest in the co-generation assets,
with a net book value of approximately $101 million at December 31, 2018, located at the refinery that is exercisable upon the
occurrence of (i) certain bankruptcy events or (ii) other events of default coupled with specific reductions in steam output at the
facility and a downgrade of Mississippi Power's credit rating to below investment grade by two of the three rating agencies.
Under the terms of the PPA and the expansion PPA for Southern Power's Plant Mankato, which was acquired in 2016,
approximately $563 million of assets, primarily related to property, plant, and equipment, are subject to lien at December 31,
2018. See Note 15 under "Southern Power – Sales of Natural Gas Plants" for additional information regarding the proposed sale
of Plant Mankato.
See Note 3 under "General Litigation Matters – Southern Power" for information regarding liens on Southern Power's Roserock
facility.
See Note 8 under "Secured Debt" for information regarding debt secured by certain assets of Georgia Power, Mississippi Power,
and Southern Company Gas.
6. ASSET RETIREMENT OBLIGATIONS
AROs are computed as the present value of the estimated costs for an asset's future retirement and are recorded in the period in
which the liability is incurred. The estimated costs are capitalized as part of the related long-lived asset and depreciated over the
asset's useful life. In the absence of quoted market prices, AROs are estimated using present value techniques in which estimates
of future cash outlays associated with the asset retirements are discounted using a credit-adjusted risk-free rate. Estimates of the
timing and amounts of future cash outlays are based on projections of when and how the assets will be retired and the cost of
future removal activities. Each traditional electric operating company and natural gas distribution utility has received accounting
guidance from its state PSC or applicable state regulatory agency allowing the continued accrual or recovery of other retirement
costs for long-lived assets that it does not have a legal obligation to retire. Accordingly, the accumulated removal costs for these
obligations are reflected in the balance sheets as regulatory liabilities and amounts to be recovered are reflected in the balance
sheets as regulatory assets.
The ARO liabilities for the traditional electric operating companies primarily relate to facilities that are subject to the CCR Rule,
principally ash ponds. In addition, Alabama Power and Georgia Power have retirement obligations related to the decommissioning
of nuclear facilities (Alabama Power's Plant Farley and Georgia Power's ownership interests in Plant Hatch and Plant Vogtle Units
1 and 2). See "Nuclear Decommissioning" herein for additional information. The traditional electric operating companies also
have AROs related to various landfill sites, asbestos removal, and underground storage tanks, as well as, for Alabama Power,
disposal of polychlorinated biphenyls in certain transformers and sulfur hexafluoride gas in certain substation breakers, for
Georgia Power, gypsum cells, and for Mississippi Power, mine reclamation and water wells. The ARO liability for Southern
Power primarily relates to Southern Power's solar and wind facilities, which are located on long-term land leases requiring the
restoration of land at the end of the lease.
The traditional electric operating companies and Southern Company Gas also have identified other retirement obligations, such as
obligations related to certain electric transmission and distribution facilities, certain asbestos containing material within long-term
assets not subject to ongoing repair and maintenance activities, certain wireless communication towers, the disposal of
polychlorinated biphenyls in certain transformers, leasehold improvements, equipment on customer property, and property
associated with the Southern Company system's rail lines and natural gas pipelines. However, liabilities for the removal of these
assets have not been recorded because the settlement timing for certain retirement obligations related to these assets is
indeterminable and, therefore, the fair value of the retirement obligations cannot be reasonably estimated. A liability for these
retirement obligations will be recognized when sufficient information becomes available to support a reasonable estimation of the
ARO.
Southern Company and the traditional electric operating companies will continue to recognize in their respective statements of
income allowed removal costs in accordance with regulatory treatment. Any differences between costs recognized in accordance

Mississippi Power also recorded an increase of approximately $11 million to its AROs related to an ash pond at Plant Greene
County, which is jointly-owned with Alabama Power. The revised cost estimates were based on information from feasibility
studies performed on ash ponds in use at plants operated by Alabama Power, including Plant Greene County. During the second
quarter 2018, Alabama Power's management completed its analysis of these studies which indicated that additional closure costs,
primarily related to increases in estimated ash volume, water management requirements, and design revisions, will be required to
close these ash ponds under the planned closure-in-place methodology. As the level of work becomes more defined in the next 12
months, it is likely that these cost estimates will change and the change could be material.
In December 2018, Georgia Power recorded an increase of approximately $3.1 billion to its AROs related to the CCR Rule and
the related state rule. During the second half of 2018, Georgia Power completed a strategic assessment related to its plans to close
the ash ponds at all of its generating plants in compliance with the CCR Rule and the related state rule. This assessment included
engineering and constructability studies related to design assumptions for ash pond closures and advanced engineering methods.
The results indicated that additional closure costs will be required to close these ash ponds, primarily due to changes in closure
strategies, the estimated amount of ash to be excavated, and additional water management requirements necessary to support
closure strategies. These factors also impact the estimated timing of future cash outlays.
In June 2018, Alabama Power completed an updated decommissioning cost site study for Plant Farley. The estimated cost of
decommissioning based on the study resulted in an increase in Alabama Power's ARO liability of approximately $300 million. In
December 2018, Georgia Power completed updated decommissioning cost site studies for Plant Hatch and Plant Vogtle Units 1
and 2. The estimated cost of decommissioning based on the studies resulted in an increase in Georgia Power's ARO liability of
approximately $130 million. See "Nuclear Decommissioning" below for additional information.
The 2018 reclassification of a portion of the ARO liability to liabilities held for sale by Southern Company represents the AROs
related to Gulf Power. See Note 15 under "Southern Company's Sale of Gulf Power" and "Assets Held for Sale" for additional
information.
In 2017, Alabama Power's and Georgia Power's cash flow revisions were primarily related to changes in closure strategy for ash
ponds and landfills. Georgia Power's cash flow revisions in 2017 also related to changes in closure strategy for gypsum cells.
Mississippi Power's cash flow revisions in 2017 primarily related to a revision in the closure date of its lignite mine. The
liabilities settled in 2017 for Alabama Power, Georgia Power, and Mississippi Power were primarily related to ash pond closure
activity.
The cost estimates for AROs related to the CCR Rule are based on information at December 31, 2018 using various assumptions
related to closure and post-closure costs, timing of future cash outlays, inflation and discount rates, and the potential methods for
105

complying with the CCR Rule requirements for closure. The traditional electric operating companies expect to continue to
periodically update their ARO cost estimates, which could increase further, as additional information becomes available. Absent
continued recovery of ARO costs through regulated rates, Southern Company's and the traditional electric operating companies'
results of operations, cash flows, and financial condition could be materially impacted. The ultimate outcome of this matter
cannot be determined at this time.
Nuclear Decommissioning
The NRC requires licensees of commercial nuclear power reactors to establish a plan for providing reasonable assurance of funds
for future decommissioning. Alabama Power and Georgia Power have external trust funds (Funds) to comply with the NRC's
regulations. Use of the Funds is restricted to nuclear decommissioning activities. The Funds are managed and invested in
accordance with applicable requirements of various regulatory bodies, including the NRC, the FERC, and state PSCs, as well as
the IRS. While Alabama Power and Georgia Power are allowed to prescribe an overall investment policy to the Funds' managers,
neither Southern Company nor its subsidiaries or affiliates are allowed to engage in the day-to-day management of the Funds or to
mandate individual investment decisions. Day-to-day management of the investments in the Funds is delegated to unrelated third-
party managers with oversight by the management of Alabama Power and Georgia Power. The Funds' managers are authorized,
within certain investment guidelines, to actively buy and sell securities at their own discretion in order to maximize the return on
the Funds' investments. The Funds are invested in a tax-efficient manner in a diversified mix of equity and fixed income securities
and are reported as trading securities.
Alabama Power and Georgia Power record the investment securities held in the Funds at fair value, as disclosed in Note 13, as
management believes that fair value best represents the nature of the Funds. Gains and losses, whether realized or unrealized, are
recorded in the regulatory liability for AROs in the balance sheets and are not included in net income or OCI. Fair value
adjustments and realized gains and losses are determined on a specific identification basis.
The Funds at Georgia Power participate in a securities lending program through the managers of the Funds. Under this program,
Georgia Power's Funds' investment securities are loaned to institutional investors for a fee. Securities loaned are fully
collateralized by cash, letters of credit, and/or securities issued or guaranteed by the U.S. government or its agencies or
instrumentalities. At December 31, 2018 and 2017, approximately $27 million and $76 million, respectively, of the fair market
value of Georgia Power's Funds' securities were on loan and pledged to creditors under the Funds' managers' securities lending
program. The fair value of the collateral received was approximately $28 million and $77 million at December 31, 2018 and
2017, respectively, and can only be sold by the borrower upon the return of the loaned securities. The collateral received is treated
as a non-cash item in the statements of cash flows.
Investment securities in the Funds for December 31, 2018 and 2017 were as follows:

The investment securities held in the Funds continue to be managed with a long-term focus. Accordingly, all purchases and sales
within the Funds are presented separately in the statements of cash flows as investing cash flows, consistent with the nature of the
securities and purpose for which the securities were acquired.
For Alabama Power, approximately $17 million and $18 million at December 31, 2018 and 2017, respectively, previously
recorded in internal reserves is being transferred into the Funds through 2040 as approved by the Alabama PSC. The NRC's
minimum external funding requirements are based on a generic estimate of the cost to decommission only the radioactive portions
of a nuclear unit based on the size and type of reactor. Alabama Power and Georgia Power have filed plans with the NRC
designed to ensure that, over time, the deposits and earnings of the Funds will provide the minimum funding amounts prescribed
by the NRC.
At December 31, 2018 and 2017, the accumulated provisions for the external decommissioning trust funds were as follows:

Site study cost is the estimate to decommission a specific facility as of the site study year. The decommissioning cost estimates
are based on prompt dismantlement and removal of the plant from service. The actual decommissioning costs may vary from
these estimates because of changes in the assumed date of decommissioning, changes in NRC requirements, or changes in the
assumptions used in making these estimates. The estimated costs of decommissioning at December 31, 2018 based on the most
current studies, which were each performed in 2018, were as follows:

(*) Based on Georgia Power's ownership interests.
For ratemaking purposes, Alabama Power's decommissioning costs are based on the site study and Georgia Power's
decommissioning costs are based on the NRC generic estimate to decommission the radioactive portion of the facilities and the
site study estimate for spent fuel management as of 2012. Significant assumptions used to determine these costs for ratemaking
were an estimated inflation rate of 4.5% and 2.4% for Alabama Power and Georgia Power, respectively, and an estimated trust
earnings rate of 7.0% and 4.4% for Alabama Power and Georgia Power, respectively.
Amounts previously contributed to the Funds for Plant Farley are currently projected to be adequate to meet the decommissioning
obligations. Alabama Power will continue to provide site-specific estimates of the decommissioning costs and related projections
of funds in the external trust to the Alabama PSC and, if necessary, would seek the Alabama PSC's approval to address any
changes in a manner consistent with NRC and other applicable requirements.
Under the 2013 ARP, the Georgia PSC approved Georgia Power's annual decommissioning cost for ratemaking of $4 million and
$2 million for Plant Hatch and Plant Vogtle Units 1 and 2, respectively. Georgia Power expects the Georgia PSC to review and
adjust, if necessary, the amounts collected in rates for nuclear decommissioning costs in the Georgia Power 2019 Base Rate Case.
7. CONSOLIDATED ENTITIES AND EQUITY METHOD INVESTMENTS
The registrants may hold ownership interests in a number of business ventures with varying ownership structures. Partnership
interests and other variable interests are evaluated to determine if each entity is a VIE. If a venture is a VIE for which a registrant
is the primary beneficiary, the assets, liabilities, and results of operations of the entity are consolidated. The registrants reassess
the conclusion as to whether an entity is a VIE upon certain occurrences, which are deemed reconsideration events.
For entities that are not determined to be VIEs, the registrants evaluate whether they have control or significant influence over the
investee to determine the appropriate consolidation and presentation. Generally, entities under the control of a registrant are
consolidated, and entities over which a registrant can exert significant influence, but which a registrant does not control, are
accounted for under the equity method of accounting. However, the registrants may also invest in partnerships and limited
liability companies that maintain separate ownership accounts. All such investments are required to be accounted for under the
equity method unless the interest is so minor that there is virtually no influence over operating and financial policies, as are all
investments in joint ventures.
Investments accounted for under the equity method are recorded within equity investments in unconsolidated subsidiaries in the
balance sheets and, for Southern Company and Southern Company Gas, the equity income is recorded within earnings from
equity method investments in the statements of income. See "SEGCO" and "Southern Company Gas" herein for additional
information.

NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
SEGCO
Alabama Power and Georgia Power own equally all of the outstanding capital stock of SEGCO, which owns electric generating
units with a total rated capacity of 1,020 MWs, as well as associated transmission facilities. Alabama Power and Georgia Power
account for SEGCO using the equity method; Southern Company consolidates SEGCO. SEGCO uses natural gas as the primary
fuel source for 1,000 MWs of its generating capacity. The capacity of these units is sold equally to Alabama Power and Georgia
Power. Alabama Power and Georgia Power make payments sufficient to provide for the operating expenses, taxes, interest
expense, and a ROE. The share of purchased power included in purchased power, affiliates in the statements of income totaled
$102 million in 2018, $76 million in 2017, and $55 million in 2016 for Alabama Power and $105 million in 2018, $78 million in
2017, and $57 million in 2016 for Georgia Power.
SEGCO paid $18 million of dividends in 2018 and $24 million in each of 2017 and 2016, of which one-half of each was paid to
each of Alabama Power and Georgia Power. In addition, Alabama Power and Georgia Power each recognize 50% of SEGCO's net
income.
Alabama Power, which owns and operates a generating unit adjacent to the SEGCO generating units, has a joint ownership
agreement with SEGCO for the ownership of an associated gas pipeline. Alabama Power owns 14% of the pipeline with the
remaining 86% owned by SEGCO.
See Note 9 under "Guarantees" for additional information regarding guarantees of Alabama Power and Georgia Power related to
SEGCO.
Southern Power
Variable Interest Entities
Southern Power has certain wholly-owned subsidiaries that are determined to be VIEs. Southern Power is considered the primary
beneficiary of these VIEs because it controls the most significant activities of the VIEs, including operating and maintaining the
respective assets, and has the obligation to absorb expected losses of these VIEs to the extent of its equity interests.
SP Solar
On May 22, 2018, Southern Power sold a noncontrolling 33% limited partnership interest in SP Solar to Global Atlantic Financial
Group Limited (Global Atlantic). See Note 15 under "Southern Power" for additional information. A wholly-owned subsidiary of
Southern Power is the general partner and holds a 1% ownership interest in SP Solar and another wholly-owned subsidiary of
Southern Power owns the remaining 66% ownership in SP Solar. SP Solar qualifies as a VIE since the arrangement is structured
as a limited partnership and the 33% limited partner does not have substantive kick-out rights against the general partner.
Southern Power previously consolidated SP Solar and will continue to do so as the primary beneficiary of the VIE since it
controls the most significant activities of the partnership, including operating and maintaining its assets.
At December 31, 2018, SP Solar had total assets of $6.3 billion, total liabilities of $113 million, and noncontrolling interests of
$1.2 billion. Cash distributions from SP Solar are allocated 67% to Southern Power and 33% to Global Atlantic in accordance
with their partnership interest percentage. Under the terms of the limited partnership agreement, distributions without limited
partner consent are limited to available cash and SP Solar is obligated to distribute all such available cash to its partners each
quarter. Available cash includes all cash generated in the quarter subject to the maintenance of appropriate operating reserves.
Transfers and sales of the assets in the VIE are subject to limited partner consent and the liabilities do not have recourse to the
general credit of Southern Power. Liabilities consist of customary working capital items and do not include any long-term debt.
SP Wind
On December 11, 2018, Southern Power sold a noncontrolling tax-equity interest in SP Wind to three financial investors. SP Wind
owns eight operating wind farms. See Note 15 under "Southern Power" for additional information. Southern Power owns 100% of
the class B membership interests and the three financial investors own 100% of the Class A membership interests. SP Wind
qualifies as a VIE since the structure of the arrangement is similar to a limited partnership and the Class A members do not have
substantive kick-out rights against Southern Power. Southern Power previously consolidated SP Wind and will continue to do so
as the primary beneficiary of the VIE since it controls the most significant activities of the entity, including operating and
maintaining its assets.
At December 31, 2018, SP Wind had total assets of $2.5 billion, total liabilities of $51 million, and noncontrolling interests of $47
million. Under the terms of the limited liability agreement, distributions without Class A member consent are limited to available
cash and SP Wind is obligated to distribute all such available cash to its members each quarter. Available cash includes all cash
109
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
generated in the quarter subject to the maintenance of appropriate operating reserves. Cash distributions from SP Wind are
generally allocated 60% to Southern Power and 40% to the three financial investors in accordance with the limited liability
agreement.
Transfers and sales of the assets in the VIE are subject to Class A member consent and the liabilities do not have recourse to the
general credit of Southern Power. Liabilities consist of customary working capital items and do not include any long-term debt.
Redeemable Noncontrolling Interests
In April 2017, Southern Power reclassified approximately $114 million from redeemable noncontrolling interests to non-
redeemable noncontrolling interests due to the expiration of an option allowing SunPower Corporation to require Southern Power
to purchase its redeemable noncontrolling interest at fair market value. In addition, in October 2017, Turner Renewable Energy,
LLC redeemed at fair value its 10% interest of redeemable noncontrolling interest in certain of Southern Power's solar facilities.
At December 31, 2018 and 2017, there were no outstanding redeemable noncontrolling interests.

SouthStar, previously a joint venture owned 85% by Southern Company Gas and 15% by Piedmont, was the only VIE for which
Southern Company Gas was the primary beneficiary, prior to October 2016 when Southern Company Gas completed its purchase
of Piedmont's remaining interest in SouthStar.
In 2015, Georgia Natural Gas Company (GNG), a 100%-owned, direct subsidiary of Southern Company Gas, notified Piedmont
of its election, pursuant to a change in control of SouthStar, to purchase Piedmont's 15% interest in SouthStar at fair market value.
This purchase was contingent upon the closing of the merger between Piedmont and Duke Energy Corporation (Duke Energy). In
October 2016, after Piedmont and Duke Energy completed their merger, GNG completed its purchase of Piedmont's interest in
SouthStar and paid a purchase price of $160 million and $15 million for Piedmont's share of SouthStar's 2016 earnings through
the date of acquisition.
Southern Company Gas' cash flows used for financing activities included SouthStar's distribution to Piedmont for its portion of
SouthStar's annual earnings from the previous year. For the successor period of July 1, 2016 through December 31, 2016,
SouthStar made a distribution of $15 million upon completion of the purchase of Piedmont's interest in SouthStar. For the
predecessor period of January 1, 2016 through June 30, 2016, SouthStar distributed $19 million to Piedmont.

In 2014, Southern Company Gas entered into a partnership in which it holds a 20% ownership interest in the PennEast Pipeline,
an interstate pipeline company formed to develop and operate a 118-mile natural gas pipeline between New Jersey and
Pennsylvania. The initial transportation capacity of 1.0 Bcf per day, is under long-term contracts, mainly with public utilities and
other market-serving entities, such as electric generation companies, in New Jersey, Pennsylvania, and New York.
Also in 2014, Southern Company Gas entered into a project in which it holds a 5% ownership interest in the Atlantic Coast
Pipeline, an interstate pipeline company formed to develop and operate a 594-mile natural gas pipeline in North Carolina,
Virginia, and West Virginia with initial transportation capacity of 1.5 Bcf per day.
See Note 2 under "FERC Matters – Southern Company Gas" for additional information on these pipeline projects.

DOE Loan Guarantee Borrowings
Pursuant to the loan guarantee program established under Title XVII of the Energy Policy Act of 2005 (Title XVII Loan
Guarantee Program), Georgia Power and the DOE entered into the Loan Guarantee Agreement in 2014, under which the DOE
agreed to guarantee the obligations of Georgia Power under a note purchase agreement (FFB Note Purchase Agreement) among
the DOE, Georgia Power, and the FFB and a related promissory note (FFB Promissory Note). The FFB Note Purchase Agreement
and the FFB Promissory Note provide for a multi-advance term loan facility (FFB Credit Facility), under which Georgia Power
may make term loan borrowings through the FFB.
In July 2017, Georgia Power entered into an amendment to the Loan Guarantee Agreement (LGA Amendment) in connection with
the DOE's consent to Georgia Power's entry into the Vogtle Services Agreement and the related intellectual property licenses (IP
Licenses).
Under the terms of the Loan Guarantee Agreement, upon termination of the Vogtle 3 and 4 Agreement, further advances are
conditioned upon the DOE's approval of any agreements entered into in replacement of the Vogtle 3 and 4 Agreement. Under the
terms of the LGA Amendment, Georgia Power will not request any advances unless and until certain conditions are satisfied,
including (i) receipt of the DOE's approval of the Bechtel Agreement (together with the Vogtle Services Agreement and the IP
Licenses, the Replacement EPC Arrangements) and (ii) Georgia Power's entry into a further amendment to the Loan Guarantee
Agreement with the DOE to reflect the Replacement EPC Arrangements.
Proceeds of advances made under the FFB Credit Facility are used to reimburse Georgia Power for Eligible Project Costs.
Aggregate borrowings under the FFB Credit Facility may not exceed the lesser of (i) 70% of Eligible Project Costs or (ii)
approximately $3.46 billion.
In September 2017, the DOE issued a conditional commitment to Georgia Power for up to approximately $1.67 billion of
additional guaranteed loans under the Loan Guarantee Agreement. This conditional commitment expires on March 31, 2019,
subject to any further extension approved by the DOE. Final approval and issuance of these additional loan guarantees by the
DOE cannot be assured and are subject to the negotiation of definitive agreements, completion of due diligence by the DOE,
receipt of any necessary regulatory approvals, and satisfaction of other conditions.
All borrowings under the FFB Credit Facility are full recourse to Georgia Power, and Georgia Power is obligated to reimburse the
DOE for any payments the DOE is required to make to the FFB under the guarantee. Georgia Power's reimbursement obligations
to the DOE are full recourse and secured by a first priority lien on (i) Georgia Power's 45.7% undivided ownership interest in
Plant Vogtle Units 3 and 4 (primarily the units under construction, the related real property, and any nuclear fuel loaded in the
reactor core) and (ii) Georgia Power's rights and obligations under the principal contracts relating to Plant Vogtle Units 3 and 4.
There are no restrictions on Georgia Power's ability to grant liens on other property.
In addition to the conditions described above, future advances are subject to satisfaction of customary conditions, as well as
certification of compliance with the requirements of the Title XVII Loan Guarantee Program, including accuracy of project-
related representations and warranties, delivery of updated project-related information, and evidence of compliance with the
116
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
prevailing wage requirements of the Davis-Bacon Act of 1931, as amended, and certification from the DOE's consulting engineer
that proceeds of the advances are used to reimburse Eligible Project Costs.
Upon satisfaction of all conditions described above, advances may be requested under the FFB Credit Facility on a quarterly basis
through 2020. The final maturity date for each advance under the FFB Credit Facility is February 20, 2044. Interest is payable
quarterly and principal payments will begin on February 20, 2020. Borrowings under the FFB Credit Facility will bear interest at
the applicable U.S. Treasury rate plus a spread equal to 0.375%.
At both December 31, 2018 and 2017, Georgia Power had $2.6 billion of borrowings outstanding under the FFB Credit Facility.
Under the Loan Guarantee Agreement, Georgia Power is subject to customary borrower affirmative and negative covenants and
events of default. In addition, Georgia Power is subject to project-related reporting requirements and other project-specific
covenants and events of default.
In the event certain mandatory prepayment events (including any decision not to continue construction of Plant Vogtle Units 3 and
4) occur, the FFB's commitment to make further advances under the FFB Credit Facility will terminate and Georgia Power will be
required to prepay the outstanding principal amount of all borrowings under the FFB Credit Facility over a period of five years
(with level principal amortization). Among other things, these mandatory prepayment events include (i) the termination of the
Vogtle Services Agreement or rejection of the Vogtle Services Agreement in bankruptcy if Georgia Power does not maintain
access to intellectual property rights under the IP Licenses; (ii) a decision by Georgia Power not to continue construction of Plant
Vogtle Units 3 and 4; (iii) cancellation of Plant Vogtle Units 3 and 4 by the Georgia PSC, or by Georgia Power if authorized by
the Georgia PSC; and (iv) cost disallowances by the Georgia PSC that could have a material adverse effect on completion of Plant
Vogtle Units 3 and 4 or Georgia Power's ability to repay the outstanding borrowings under the FFB Credit Facility. Under certain
circumstances, insurance proceeds and any proceeds from an event of taking must be applied to immediately prepay outstanding
borrowings under the FFB Credit Facility. In addition, if Georgia Power discontinues construction of Plant Vogtle Units 3 and 4,
Georgia Power would be obligated to immediately repay a portion of the outstanding borrowings under the FFB Credit Facility to
the extent such outstanding borrowings exceed 70% of Eligible Project Costs, net of the proceeds received by Georgia Power
under the Guarantee Settlement Agreement. Georgia Power also may voluntarily prepay outstanding borrowings under the FFB
Credit Facility. Under the FFB Credit Facility, any prepayment (whether mandatory or optional) will be made with a make-whole
premium or discount, as applicable.
In connection with any cancellation of Plant Vogtle Units 3 and 4 that results in a mandatory prepayment event, the DOE may
elect to continue construction of Plant Vogtle Units 3 and 4. In such an event, the DOE will have the right to assume Georgia
Power's rights and obligations under the principal agreements relating to Plant Vogtle Units 3 and 4 and to acquire all or a portion
of Georgia Power's ownership interest in Plant Vogtle Units 3 and 4.
Other Long-Term Debt
Alabama Power
Alabama Power has formed a wholly-owned trust subsidiary for the purpose of issuing preferred securities. The proceeds of the

(b) Southern Power's subsidiaries are not parties to its bank credit arrangement.
(c) Southern Company Gas provides a parent guarantee of the obligations of its subsidiary Southern Company Gas Capital, which is the borrower of $1.4 billion
($1.395 billion unused) of this arrangement. Southern Company Gas' committed credit arrangement also includes $500 million (all unused) for which Nicor
Gas is the borrower and which is restricted for working capital needs of Nicor Gas. Pursuant to this multi-year credit arrangement, the allocations between
Southern Company Gas Capital and Nicor Gas may be adjusted. See "Structural Considerations" herein for additional information.
(d) Amounts used are for letters of credit.
(e) Excludes $280 million of committed credit arrangements of Gulf Power, which was sold on January 1, 2019. See Note 15 under "Southern Company's Sale of
Gulf Power" for additional information.
Most of the bank credit arrangements require payment of commitment fees based on the unused portion of the commitments or
the maintenance of compensating balances with the banks. Commitment fees average less than 1/4 of 1% for Southern Company,
the traditional electric operating companies, Southern Power, Southern Company Gas, and Nicor Gas. Compensating balances are
not legally restricted from withdrawal.
Subject to applicable market conditions, Southern Company and its subsidiaries expect to renew or replace their bank credit
arrangements as needed, prior to expiration. In connection therewith, Southern Company and its subsidiaries may extend the
maturity dates and/or increase or decrease the lending commitments thereunder.
Southern Company's, Southern Company Gas', and Nicor Gas' credit arrangements contain covenants that limit debt levels to 70%
of total capitalization, as defined in the agreements, and most of the other subsidiaries' bank credit arrangements contain
covenants that limit debt levels to 65% of total capitalization, as defined in the agreements. For purposes of these definitions, debt
excludes the long-term debt payable to affiliated trusts and, in certain arrangements, other hybrid securities. Additionally, for
Southern Company and Southern Power, for purposes of these definitions, debt would exclude any project debt incurred by
certain subsidiaries of Southern Power to the extent such debt is non-recourse to Southern Power and capitalization would
exclude the capital stock or other equity attributable to such subsidiaries. At December 31, 2018, Southern Company, the
traditional electric operating companies, Southern Power, Southern Company Gas, and Nicor Gas were each in compliance with
their respective debt limit covenants.
A portion of the unused credit with banks is allocated to provide liquidity support to the revenue bonds of the traditional electric
operating companies and the commercial paper programs of Southern Company, the traditional electric operating companies,
Southern Power, Southern Company Gas, and Nicor Gas. The amount of variable rate revenue bonds of the traditional electric
119
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
operating companies outstanding requiring liquidity support at December 31, 2018 was approximately $1.6 billion (comprised of
approximately $854 million at Alabama Power, $659 million at Georgia Power, $82 million at Gulf Power, and $40 million at
Mississippi Power). In addition, at December 31, 2018, the traditional electric operating companies had approximately $403
million (comprised of approximately $345 million at Georgia Power and $58 million at Gulf Power) of revenue bonds outstanding
that are required to be remarketed within the next 12 months. See Note 15 under "Southern Company's Sale of Gulf Power" for
information regarding the sale of Gulf Power on January 1, 2019. Subsequent to December 31, 2018, Georgia Power redeemed
approximately $108 million of obligations related to outstanding variable rate pollution control revenue bonds.
In addition to its credit arrangement described above, Southern Power also has a $120 million continuing letter of credit facility
expiring in 2021 for standby letters of credit. At December 31, 2018, $103 million has been used for letters of credit, primarily as
credit support for PPA requirements, and $17 million was unused. At December 31, 2017, the total amount available under this
facility was $19 million. Southern Power's subsidiaries are not parties to this letter of credit facility. Also, at December 31, 2018
and 2017, Southern Power had $103 million and $113 million, respectively, of cash collateral posted related to PPA requirements,
which is included in other deferred charges and assets in Southern Power's consolidated balance sheets.
Notes Payable
Southern Company, Alabama Power, Georgia Power, Southern Power, Southern Company Gas, Nicor Gas, and SEGCO make
short-term borrowings primarily through commercial paper programs that have the liquidity support of the committed bank credit
arrangements described above under "Bank Credit Arrangements." Southern Power's subsidiaries are not parties to its commercial
paper program. Southern Company Gas maintains commercial paper programs at Southern Company Gas Capital and at Nicor
Gas. Nicor Gas' commercial paper program supports working capital needs at Nicor Gas as Nicor Gas is not permitted to make
money pool loans to affiliates. All of Southern Company Gas' other subsidiaries benefit from Southern Company Gas Capital's
commercial paper program. See "Structural Considerations" herein for additional information.
In addition, Southern Company and certain of its subsidiaries have entered into various bank term loan agreements. Unless
otherwise stated, the proceeds of these loans were used to repay existing indebtedness and for general corporate purposes,
including working capital and, for the subsidiaries, their continuous construction programs.

The outstanding bank term loans at December 31, 2018 have covenants that limit debt levels to a percentage of total
capitalization. The percentage is 70% for Southern Company and 65% for Alabama Power and Southern Power, as defined in the
agreements. For purposes of these definitions, debt excludes any long-term debt payable to affiliated trusts and other hybrid
securities. Additionally, for Southern Company and Southern Power, for purposes of these definitions, debt excludes any project
debt incurred by certain subsidiaries of Southern Power to the extent such debt is non-recourse to Southern Power and
capitalization excludes the capital stock or other equity attributable to such subsidiary. At December 31, 2018, each of Southern
Company, Alabama Power, and Southern Power was in compliance with its debt limits.
Except as otherwise described herein, Southern Company and its subsidiaries used the proceeds of bank loans for long-term debt
redemptions and maturities, to repay short-term indebtedness, and for general corporate purposes, including working capital.

Redeemable Preferred Stock of Subsidiaries
Prior to 2017, each of the traditional electric operating companies had outstanding preferred and/or preference stock. During
2017, Alabama Power and Gulf Power redeemed all of their outstanding preference stock and Georgia Power redeemed all of its
outstanding preferred and preference stock. During 2018, Mississippi Power redeemed all of its outstanding preferred stock. The
remaining preferred stock of Alabama Power contains a feature that allows the holders to elect a majority of such subsidiary's
board of directors if preferred dividends are not paid for four consecutive quarters. Because such a potential redemption-
triggering event is not solely within the control of Alabama Power, this preferred stock is presented as "Redeemable Preferred
Stock of Subsidiaries" on Southern Company's balance sheets and statements of capitalization in a manner consistent with
temporary equity under applicable accounting standards.

Alabama Power has preferred stock, Class A preferred stock, and common stock outstanding. Alabama Power also has authorized
preference stock, none of which is outstanding. Alabama Power's preferred stock and Class A preferred stock, without preference
between classes, rank senior to Alabama Power's common stock with respect to payment of dividends and voluntary and
involuntary dissolution. The preferred stock and Class A preferred stock of Alabama Power contain a feature that allows the
holders to elect a majority of Alabama Power's board of directors if preferred dividends are not paid for four consecutive quarters.
Because such a potential redemption-triggering event is not solely within the control of Alabama Power, the preferred stock and

Stock, Cumulative, Par Value $1 Per Share (Stated Capital $25 Per Share). The proceeds were used in October 2017 to redeem all
2 million shares ($50 million aggregate stated capital) of 6.50% Series Preference Stock, 6 million shares ($150 million aggregate

Preferred Stock and for other general corporate purposes, including Alabama Power's continuous construction program.
There were no changes for the year ended December 31, 2018 in redeemable preferred stock of Alabama Power.
Georgia Power
Georgia Power has preferred stock, Class A preferred stock, preference stock, and common stock authorized, but only common
stock outstanding as of December 31, 2018 and 2017. In October 2017, Georgia Power redeemed all 1.8 million shares ($45
million aggregate liquidation amount) of its 6.125% Series Class A Preferred Stock and 2.25 million shares ($225 million
aggregate liquidation amount) of its 6.50% Series 2007A Preference Stock.
Mississippi Power
Mississippi Power has preferred stock and common stock authorized, but only common stock outstanding as of December 31,
2018. Mississippi Power previously had preferred stock that contained a feature allowing the holders to elect a majority of
Mississippi Power's board of directors if preferred dividends were not paid for four consecutive quarters. Because such a potential
redemption-triggering event was not solely within the control of Mississippi Power, this preferred stock was presented as
"Cumulative Redeemable Preferred Stock" on Mississippi Power's balance sheets and statements of capitalization in a manner
consistent with temporary equity under applicable accounting standards.
On October 23, 2018, Mississippi Power completed the redemption of all 8,867 outstanding shares ($886,700 aggregate par
value) of its 4.40% Series Preferred Stock, all 8,643 outstanding shares ($864,300 aggregate par value) of its 4.60% Series
Preferred Stock, all 16,700 outstanding shares ($1.67 million aggregate par value) of its 4.72% Series Preferred Stock, and all
1,200,000 outstanding depositary shares ($30 million aggregate stated value), each representing a 1/4th interest in a share of its
5.25% Series Preferred Stock.
Dividend Restrictions
The income of Southern Company is derived primarily from equity in earnings of its subsidiaries. At December 31, 2018,
consolidated retained earnings included $4.9 billion of undistributed retained earnings of the subsidiaries.
The traditional electric operating companies and Southern Power can only pay dividends to Southern Company out of retained
earnings or paid-in-capital.
See Note 7 under "Southern Power" for information regarding the distribution requirements for certain Southern Power
subsidiaries.
The authority of the natural gas distribution utilities to pay dividends to Southern Company Gas is subject to regulation. By
regulation, Nicor Gas is restricted, to the extent of its retained earnings balance, in the amount it can dividend or loan to affiliates
and is not permitted to make money pool loans to affiliates. At December 31, 2018, the amount of Southern Company Gas'
subsidiary retained earnings restricted for dividend payment totaled $814 million.

Alabama Power Company 2018 Annual Report
Structural Considerations
Since Southern Company and Southern Company Gas are holding companies, the right of Southern Company and Southern
Company Gas and, hence, the right of creditors of Southern Company or Southern Company Gas to participate in any distribution
of the assets of any respective subsidiary of Southern Company or Southern Company Gas, whether upon liquidation,
reorganization or otherwise, is subject to prior claims of creditors and preferred stockholders of such subsidiary.
Southern Company Gas' 100%-owned subsidiary, Southern Company Gas Capital, was established to provide for certain of
Southern Company Gas' ongoing financing needs through a commercial paper program, the issuance of various debt, hybrid
securities, and other financing arrangements. Southern Company Gas fully and unconditionally guarantees all debt issued by
Southern Company Gas Capital. Nicor Gas is not permitted by regulation to make loans to affiliates or utilize Southern Company
Gas Capital for its financing needs.
Southern Power Company's senior notes, bank term loans, commercial paper, and bank credit arrangement are unsecured senior
indebtedness, which rank equally with all other unsecured and unsubordinated debt of Southern Power Company. Southern
Power's subsidiaries are not issuers, borrowers, or obligors, as applicable, under the senior notes, borrowings from financial
institutions, commercial paper, or the bank credit arrangement. The senior notes, borrowings from financial institutions,
commercial paper, and the bank credit arrangement are effectively subordinated to any future secured debt of Southern Power
Company and any potential claims of creditors of Southern Power's subsidiaries.

Fuel and Power Purchase Agreements
Non-Affiliate
To supply a portion of the fuel requirements of the Southern Company system's electric generating plants, the Southern Company
system has entered into various long-term commitments not recognized on the balance sheets for the procurement and delivery of
fossil fuel and, for Alabama Power and Georgia Power, nuclear fuel. Fuel expense in 2018, 2017, and 2016 for the Southern
Company system is shown below, the majority of which was purchased under long-term commitments.

Each registrant expects that a substantial amount of its future fuel needs will continue to be purchased under long-term
commitments.
The traditional electric operating companies have entered into various non-affiliate long-term PPAs, some of which are accounted
for as leases. For Alabama Power and Georgia Power, most long-term PPAs include capacity and energy components. Mississippi
Power's long-term PPAs are associated with solar facilities and only include an energy component. For the traditional electric
operating companies, the energy-related costs associated with PPAs are recoverable through fuel cost recovery provisions.
Total capacity expense under these non-affiliate PPAs accounted for as operating leases in 2018, 2017, and 2016 was as follows:

In addition, Georgia Power's non-affiliate energy-only solar PPAs accounted for as leases contained contingent rent expense of
$43 million, $44 million, and $18 million for 2018, 2017, and 2016, respectively. Mississippi Power's energy-only solar PPAs
accounted for as operating leases contained contingent rent expense of $10 million, $5 million, and an immaterial amount for
2018, 2017, and 2016, respectively. Contingent rents are recognized as services are performed.

In addition, Georgia Power has commitments regarding a portion of a 5% interest in the original cost of Plant Vogtle Units 1 and 2
owned by MEAG Power that are in effect until the latter of the retirement of the plant or the latest stated maturity date of MEAG
Power's bonds issued to finance such ownership interest. The payments for capacity are required whether or not any capacity is

available. The energy cost is a function of each unit's variable operating costs. Portions of the capacity payments relate to costs in
excess of MEAG Power's Plant Vogtle Units 1 and 2 allowed investment for ratemaking purposes. The present value of these
portions at the time of the disallowance was written off. Generally, the cost of such capacity and energy is included in purchased
power in Southern Company's statements of income and in purchased power, non-affiliates in Georgia Power's statements of
income. Georgia Power's capacity payments related to this commitment totaled $8 million, $9 million, and $11 million in 2018,
2017, and 2016, respectively. At December 31, 2018, Georgia Power's estimated long-term obligations related to this commitment
totaled $59 million, consisting of $6 million for 2019, $5 million for 2020, $5 million for 2021, $4 million for 2022, $3 million
for 2023, and $36 million for 2024 and thereafter.
SCS may enter into various types of wholesale energy and natural gas contracts acting as an agent for the traditional electric
operating companies and Southern Power. Under these agreements, each of the traditional electric operating companies and
Southern Power may be jointly and severally liable. Accordingly, Southern Company has entered into keep-well agreements with
each of the traditional electric operating companies to ensure they will not subsidize or be responsible for any costs, losses,
liabilities, or damages resulting from the inclusion of Southern Power as a contracting party under these agreements.
Affiliate
Georgia Power has also entered into affiliate long-term PPAs with Southern Power, some of which Georgia Power accounts for as
leases. Georgia Power's total capacity expense under these affiliate PPAs accounted for as leases was $93 million, $107 million,
and $133 million in 2018, 2017, and 2016, respectively. In addition, Georgia Power's energy-only solar PPAs with Southern
Power accounted for as leases contained contingent rent expense of $29 million, $29 million, and $21 million for 2018, 2017, and
2016, respectively.

Pipeline Charges, Storage Capacity, and Gas Supply
Southern Company Gas has commitments for pipeline charges, storage capacity, and gas supply, which include charges
recoverable through natural gas cost recovery mechanisms, or alternatively, billed to marketers selling retail natural gas, as well as
demand charges associated with Southern Company Gas' wholesale gas services. Gas supply commitments include amounts for
gas commodity purchases associated with Southern Company Gas' gas marketing services of 47 million mmBtu at floating gas
prices calculated using forward natural gas prices at December 31, 2018 and valued at $150 million. Southern Company Gas
provides guarantees to certain gas suppliers for certain of its subsidiaries in support of payment obligations.

In addition to the operating lease PPAs discussed previously, the Southern Company system has operating lease agreements with
various terms and expiration dates. The traditional electric operating companies' operating leases primarily relate to facilities, coal
railcars, vehicles, cellular tower space, and other equipment. Southern Power's operating leases primarily relate to land for solar
and wind facilities and are recognized on a straight-line basis over the minimum lease term, plus any renewal periods necessary to
cover the expected life of the respective facility. Southern Company Gas' operating leases primarily relate to facilities and
vehicles.

For the traditional electric operating companies, a majority of the railcar and barge lease expenses are recoverable through fuel
cost recovery provisions.
In addition to the above rental commitments, Alabama Power and Georgia Power have potential obligations upon expiration of
certain railcar leases with respect to the residual value of the leased property. These leases have terms expiring in 2023 for
Alabama Power and in 2024 for Georgia Power with maximum obligations under these leases of $12 million for Alabama Power
and $9 million for Georgia Power. At the termination of the leases, Alabama Power and Georgia Power may renew the leases,
exercise their purchase options, or the property can be sold to a third party. Alabama Power and Georgia Power expect that the fair
market value of the leased property would substantially reduce or, for Alabama Power, potentially eliminate the loss under the
residual value obligations.
Guarantees
Alabama Power has guaranteed unconditionally the obligation of SEGCO under an installment sale agreement for the purchase of
certain pollution control facilities at SEGCO's generating units, pursuant to which $25 million principal amount of pollution
control revenue bonds are outstanding and mature in June 2019. Alabama Power also guaranteed a $100 million principal amount
long-term bank loan entered into by SEGCO on November 28, 2018. Georgia Power has agreed to reimburse Alabama Power for
the portion of such obligations corresponding to Georgia Power's proportionate ownership of SEGCO's stock if Alabama Power is
called upon to make such payment under its guarantee. At December 31, 2018, the capitalization of SEGCO consisted of $90
million of equity and $125 million of long-term debt, on which the annual interest requirement is $4 million. In addition, SEGCO
had short-term debt outstanding of $5 million. See Note 7 under "SEGCO" for additional information.
In 2013, Georgia Power entered into an agreement that requires Georgia Power to guarantee certain payments of a gas supplier for
Plant McIntosh for a period up to 15 years. The agreement was subsequently amended on May 31, 2018. The guarantee is
expected to be terminated if certain events occur by October 2019. In the event the gas supplier defaults on payments, the
maximum potential exposure under the guarantee and amendment is approximately $30 million.
In October 2017, Atlantic Coast Pipeline executed a $3.4 billion revolving credit facility with a stated maturity date of October
2021. Southern Company Gas entered into a guarantee agreement to support its share of the revolving credit facility. Southern
Company Gas' maximum exposure to loss under the terms of the guarantee is limited to 5% of the outstanding borrowings under
the credit facility, and totaled $72 million as of December 31, 2018. See Note 2 under "FERC Matters – Southern Company Gas"
for additional information regarding the Atlantic Coast Pipeline.
As discussed above under "Operating Leases," Alabama Power and Georgia Power have entered into certain residual value
guarantees related to railcar leases.
10. INCOME TAXES
Southern Company files a consolidated federal income tax return and the registrants file various state income tax returns, some of
which are combined or unitary. Under a joint consolidated income tax allocation agreement, each Southern Company subsidiary's
current and deferred tax expense is computed on a stand-alone basis and no subsidiary is allocated more current expense than

tax allocation agreement as of May 9, 2016 and July 1, 2016, respectively. See Note 15 for additional information on these
acquisitions, as well as disposition activity during 2018. In accordance with IRS regulations, each company is jointly and
severally liable for the federal tax liability. Prior to the Merger, Southern Company Gas filed a U.S. federal consolidated income
tax return and various state income tax returns.
Federal Tax Reform Legislation
Following the enactment of the Tax Reform Legislation, the SEC staff issued Staff Accounting Bulletin 118 – "Income Tax
Accounting Implications of the Tax Cuts and Jobs Act" (SAB 118), which provided for a measurement period of up to one year
from the enactment date to complete accounting under GAAP for the tax effects of the legislation. Due to the complex and
comprehensive nature of the enacted tax law changes and their application under GAAP, the registrants considered all amounts
recorded in the financial statements as a result of the Tax Reform Legislation "provisional" as discussed in SAB 118 and subject
to revision prior to filing the 2017 tax return in the fourth quarter 2018. As of December 31, 2018, each of the registrants
considered the measurement of impacts from the Tax Reform Legislation on deferred income tax assets and liabilities, primarily
due to the impact of the reduction of the corporate income tax rate, to be complete.
However, the IRS continues to issue regulations that provide further interpretation and guidance on the law and each respective
state's adoption of the provisions contained in the Tax Reform Legislation remains uncertain. In addition, the regulatory treatment
of certain impacts of the Tax Reform Legislation is subject to the discretion of the FERC and each state regulatory commission.
The ultimate impact of these matters cannot be determined at this time. See Note 2 for additional information.

Southern Company's and Southern Power's ITCs and PTCs generated in the current tax year and carried forward from prior tax
years that cannot be utilized in the current tax year are reclassified from current to deferred taxes in federal income tax expense in
the tables above. Southern Power's ITCs and PTCs reclassified in this manner include $128 million for 2018, $316 million for
131
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
2017, and $1.13 billion for 2016. These ITCs and PTCs for Southern Company and Southern Power are included in "Deferred Tax
Assets and Liabilities" herein.
In accordance with regulatory requirements, federal ITCs for the traditional electric operating companies and the natural gas
distribution utilities, as well as certain state ITCs for Nicor Gas, are deferred, and, upon utilization, amortized over the average
life of the related property with such amortization normally applied as a credit to reduce depreciation in the statements of income.
Southern Power's deferred federal ITCs are amortized to income tax expense over the life of the respective asset. ITCs amortized
in 2018, 2017, and 2016 were immaterial for Alabama Power, Georgia Power, Mississippi Power, and Southern Company Gas
and were as follows for Southern Company and Southern Power:

Southern Power received $5 million of cash related to federal ITCs under renewable energy initiatives in 2018. No cash was
received in 2017 or 2016. Southern Power recognized tax credits and reduced the tax basis of the asset by 50% of the ITCs
received, resulting in a net deferred tax asset. Southern Power has elected to recognize the tax benefit of this basis difference as a
reduction to income tax expense in the year in which the plant reaches commercial operation. The tax benefit of the related basis
differences reduced income tax expense by $1 million in 2018, $18 million in 2017, and $173 million in 2016. See "Unrecognized
Tax Benefits" herein for further information.
State ITCs and other state credits, which are recognized in the period in which the credits are generated, reduced Georgia Power's
income tax expense by $21 million in 2018, $37 million in 2017, and $31 million in 2016 and reduced Southern Power's income
tax expense by $32 million in 2017 and $7 million in 2016.
Southern Power's federal and state PTCs, which are recognized in the period in which the credits are generated, reduced Southern
Power's income tax expense by $141 million in 2018, $139 million in 2017, and $50 million in 2016.
Legal Entity Reorganizations
In April 2018, Southern Power completed the final stage of a legal entity reorganization of various direct and indirect subsidiaries
that own and operate substantially all of its solar facilities, including certain subsidiaries owned in partnership with various third
parties. In September 2018, Southern Power also completed a legal entity reorganization of eight operating wind facilities under a
new holding company, SP Wind. The reorganizations resulted in net state tax benefits related to certain changes in apportionment
rates totaling approximately $65 million, which were recorded in 2018.
Effective Tax Rate
Southern Company's effective tax rate is typically lower than the statutory rate due to employee stock plans' dividend deduction,
non-taxable AFUDC equity at the traditional electric operating companies, flowback of excess deferred income taxes at the
regulated utilities, and federal income tax benefits from ITCs and PTCs primarily at Southern Power. Each registrant's effective
tax rate for 2018 varied significantly as compared to 2017 due to the 14% lower 2018 federal tax rate resulting from the Tax
Reform Legislation.

The implementation of the Tax Reform Legislation significantly reduced accumulated deferred income taxes in 2017, partially
offset by bonus depreciation provisions in the PATH Act.
The traditional electric operating companies and natural gas distribution utilities have tax-related regulatory assets (deferred
income tax charges) and regulatory liabilities (deferred income tax credits). The regulatory assets are primarily attributable to tax
benefits flowed through to customers in prior years, deferred taxes previously recognized at rates lower than the current enacted
136

tax law, and taxes applicable to capitalized interest. The regulatory liabilities are primarily attributable to deferred taxes
previously recognized at rates higher than the current enacted tax law and to unamortized ITCs. See Note 2 for each registrant's
related balances at December 31, 2018 and 2017.

The estimated tax credit utilization reflects the 2018 abandonment loss related to certain Kemper County energy facility
expenditures as well as the projected taxable gains on the various sale transactions described in Note 15 and "Legal Entity
Reorganizations" herein. The expected utilization of tax credit carryforwards could be further delayed by numerous factors,
including the acquisition of additional renewable projects, the purchase of rights to additional PTCs of Plant Vogtle Units 3 and 4
pursuant to the MEAG Funding Agreement or the Global Amendments, and changes in taxable income projections. See Note 2
under "Georgia Power – Nuclear Construction" for additional information on Plant Vogtle Units 3 and 4.
At December 31, 2018, Georgia Power also had approximately $341 million in state investment and other state tax credit
carryforwards for the State of Georgia that will expire between 2020 and 2028 and are not expected to be fully utilized. Georgia
Power has a net state valuation allowance of $33 million associated with these carryforwards.
The ultimate outcome of these matters cannot be determined at this time.

Mississippi Power's tax positions increase from current and prior periods for 2017 and 2016 relate to state tax benefits, deductions
for R&E expenditures, and charitable contribution carryforwards that were impacted as a result of the settlement of R&E
expenditures associated with the Kemper County energy facility, as well as federal income tax benefits from deferred ITCs.
Mississippi Power's tax positions decrease from prior periods and the reductions due to settlements for 2017 relate primarily to the
settlement of R&E expenditures associated with the Kemper County energy facility. See Note 2 under "Mississippi Power –
Kemper County Energy Facility" and "Section 174 Research and Experimental Deduction" herein for more information.
Southern Power's increase in unrecognized tax benefits from current periods for 2016, and the decrease from prior periods for
2017 and 2016, primarily relate to federal income tax benefits from deferred ITCs.
There were no unrecognized tax benefits at December 31, 2018. The impact on the effective tax rate of Southern Company,
Mississippi Power, and Southern Power, if recognized, was as follows for 2017 and 2016:
2017

Mississippi Power's tax positions not impacting the effective tax rate for 2016 relate to deductions for R&E expenditures
associated with the Kemper County energy facility. See "Section 174 Research and Experimental Deduction" herein for more
information. These amounts are presented on a gross basis without considering the related federal or state income tax impact.
139
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
Southern Power's impact on the effective tax rate was determined based on the amount of ITCs, which were uncertain.
All of the registrants classify interest on tax uncertainties as interest expense. Accrued interest for all tax positions other than the
Section 174 R&E deductions was immaterial for all years presented. None of the registrants accrued any penalties on uncertain
tax positions.
It is reasonably possible that the amount of the unrecognized tax benefits could change within 12 months. New audit findings or
settlements associated with ongoing audits could result in significant unrecognized tax benefits. At this time, a range of
reasonably possible outcomes cannot be determined.
The IRS has finalized its audits of Southern Company's consolidated federal income tax returns through 2017, as well as the pre-
Merger Southern Company Gas tax returns. Southern Company is a participant in the Compliance Assurance Process of the IRS.
The audits for the registrants' state income tax returns have either been concluded, or the statute of limitations has expired, for
years prior to 2012.
Section 174 Research and Experimental Deduction
Southern Company, on behalf of Mississippi Power, has reflected deductions for R&E expenditures related to the Kemper County
energy facility in its federal income tax calculations since 2013 and filed amended federal income tax returns for 2008 through
2013 to also include such deductions. In September 2017, the U.S. Congress Joint Committee on Taxation approved a settlement
between Southern Company and the IRS, resolving a methodology for these deductions. As a result of this approval, Mississippi
Power recognized $176 million in 2017 of previously unrecognized tax benefits and reversed $36 million of associated accrued
interest.
11. RETIREMENT BENEFITS
The Southern Company system has a qualified defined benefit, trusteed, pension plan covering substantially all employees, with
the exception of employees at PowerSecure. The qualified defined benefit pension plan is funded in accordance with requirements
of the Employee Retirement Income Security Act of 1974, as amended (ERISA). No contributions to the qualified pension plan
were made for the year ended December 31, 2018 and no mandatory contributions to the qualified pension plan are anticipated for
the year ending December 31, 2019. The Southern Company system also provides certain non-qualified defined benefits for a
select group of management and highly compensated employees, which are funded on a cash basis. In addition, the Southern
Company system provides certain medical care and life insurance benefits for retired employees through other postretirement
benefit plans. The traditional electric operating companies fund other postretirement trusts to the extent required by their
respective regulatory commissions. Southern Company Gas has a separate unfunded supplemental retirement health care plan that
provides medical care and life insurance benefits to employees of discontinued businesses. For the year ending December 31,
2019, no other postretirement trust contributions are expected.
On January 1, 2018, the qualified defined benefit pension plan of Southern Company Gas was merged into the Southern Company
system's qualified defined benefit pension plan and the pension plan was reopened to all non-union employees of Southern
Company Gas. Prior to January 1, 2018, Southern Company Gas had a separate qualified defined benefit, trusteed, pension plan
covering certain eligible employees, which was closed in 2012 to new employees. Also on January 1, 2018, Southern Company
Gas' non-qualified retirement plans were merged into the Southern Company system's non-qualified retirement plan (defined
benefit and defined contribution).
Effective in December 2017, 538 employees transferred from SCS to Southern Power. Accordingly, Southern Power assumed
various compensation and benefit plans including participation in the Southern Company system's qualified defined benefit,
trusteed, pension plan covering substantially all employees. With the transfer of employees, Southern Power assumed the related
benefit obligations from SCS of $139 million for the qualified pension plan (along with trust assets of $138 million) and $11
million for other postretirement benefit plans, together with $36 million in prior service costs and net gains/losses in OCI. In
2018, Southern Power also began providing certain defined benefits under the non-qualified pension plan for a select group of
management and highly compensated employees. No obligation related to these benefits was assumed in the employee transfer;
however, obligations for services rendered by employees following the transfer are being recognized by Southern Power and are
funded on a cash basis. In addition, Southern Power provides certain medical care and life insurance benefits for retired
employees through other postretirement benefit plans that are funded on a cash basis. Prior to the transfer of employees in
December 2017, substantially all expenses charged by SCS, including pension and other postretirement benefit costs, were
recorded in Southern Power's other operations and maintenance expense. The disclosures included herein exclude Southern Power
for periods prior to the transfer of employees in December 2017.
On January 1, 2019, Southern Company completed the sale of Gulf Power to NextEra Energy. See Note 15 under "Southern
Company's Sale of Gulf Power" for additional information. The portion of the Southern Company system's pension and other

The registrants estimate the expected rate of return on pension plan and other postretirement benefit plan assets using a financial
model to project the expected return on each current investment portfolio. The analysis projects an expected rate of return on each
of the different asset classes in order to arrive at the expected return on the entire portfolio relying on each trust's target asset
allocation and reasonable capital market assumptions. The financial model is based on four key inputs: anticipated returns by
asset class (based in part on historical returns), each trust's target asset allocation, an anticipated inflation rate, and the projected
impact of a periodic rebalancing of each trust's portfolio.

The actuarial gain of $1.1 billion recorded in the remeasurement of the Southern Company system pension plans at December 31,
2018 was primarily due to a 69 basis point increase in the overall discount rate used to calculate the benefit obligation as a result
of higher market interest rates. The actuarial loss of $1.3 billion recorded in the remeasurement of the Southern Company system
pension plans at December 31, 2017 was primarily due to a 60 basis point decrease in the overall discount rate used to calculate
the benefit obligation as a result of lower market interest rates.

Net periodic pension cost is the sum of service cost, interest cost, and other costs netted against the expected return on plan assets.
The expected return on plan assets is determined by multiplying the expected rate of return on plan assets and the market-related
value of plan assets. In determining the market-related value of plan assets, the registrants have elected to amortize changes in the
149
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
market value of all plan assets over five years rather than recognize the changes immediately. As a result, the accounting value of
plan assets that is used to calculate the expected return on plan assets differs from the current fair value of the plan assets.
Future benefit payments reflect expected future service and are estimated based on assumptions used to measure the projected
benefit obligation for the pension plans. At December 31, 2018, estimated benefit payments were as follows:

Alabama Power Company 2018 Annual Report
Benefit Plan Assets
Pension plan and other postretirement benefit plan assets are managed and invested in accordance with all applicable
requirements, including ERISA and the Internal Revenue Code. The registrants' investment policies for both the pension plans and
the other postretirement benefit plans cover a diversified mix of assets as described below. Derivative instruments may be used to
gain efficient exposure to the various asset classes and as hedging tools. Additionally, the registrants minimize the risk of large
losses primarily through diversification but also monitor and manage other aspects of risk.
The investment strategy for plan assets related to the Southern Company system's qualified pension plan is to be broadly
diversified across major asset classes. The asset allocation is established after consideration of various factors that affect the assets
and liabilities of the pension plan including, but not limited to, historical and expected returns and interest rates, volatility,
correlations of asset classes, the current level of assets and liabilities, and the assumed growth in assets and liabilities. Because a
significant portion of the liability of the pension plans is long-term in nature, the assets are invested consistent with long-term
investment expectations for return and risk. To manage the actual asset class exposures relative to the target asset allocation, the
Southern Company system employs a formal rebalancing program. As additional risk management, external investment managers
and service providers are subject to written guidelines to ensure appropriate and prudent investment practices. Management
believes the portfolio is well-diversified with no significant concentrations of risk.
Investment Strategies and Benefit Plan Asset Fair Values
A description of the major asset classes that the pension and other postretirement benefit plans are comprised of, along with the
valuation methods used for fair value measurement, is provided below:
Description
Valuation Methodology
Domestic equity: A mix of large and small capitalization
stocks with generally an equal distribution of value and growth
attributes, managed both actively and through passive index
approaches.
International equity: A mix of growth stocks and value stocks
with both developed and emerging market exposure, managed
both actively and through passive index approaches.
Fixed income: A mix of domestic and international bonds.
Trust-owned life insurance (TOLI): Investments of taxable
trusts aimed at minimizing the impact of taxes on the portfolio.
Special situations: Investments in opportunistic strategies with
the objective of diversifying and enhancing returns and
exploiting short-term inefficiencies, as well as investments in
promising new strategies of a longer-term nature.
Real estate: Investments in traditional private market, equity-
oriented investments in real properties (indirectly through
pooled funds or partnerships) and in publicly traded real estate
securities.
Private equity: Investments in private partnerships that invest
in private or public securities typically through privately-
negotiated and/or structured transactions, including leveraged
buyouts, venture capital, and distressed debt.
Domestic and international equities such as common stocks,
American depositary receipts, and real estate investment trusts
that trade on public exchanges are classified as Level 1
investments and are valued at the closing price in the active
market. Equity funds with unpublished prices are valued as
Level 2 when the underlying holdings are comprised of Level
1 or Level 2 equity securities.
Investments in fixed income securities are generally classified
as Level 2 investments and are valued based on prices reported
in the market place. Additionally, the value of fixed income
securities takes into consideration certain items such as broker
quotes, spreads, yield curves, interest rates, and discount rates
that apply to the term of a specific instrument.
Investments in TOLI policies are classified as Level 2
investments and are valued based on the underlying
investments held in the policy's separate accounts. The
underlying assets are equity and fixed income pooled funds
that are comprised of Level 1 and Level 2 securities.
Investments in real estate, private equity, and special situations
are generally classified as Net Asset Value as a Practical
Expedient, since the underlying assets typically do not have
publicly available observable inputs. The fund manager values
the assets using various inputs and techniques depending on
the nature of the underlying investments. Techniques may
include purchase multiples for comparable transactions,
comparable public company trading multiples, discounted cash
flow analysis, prevailing market capitalization rates, recent
sales of comparable investments, and independent third-party
appraisals. The fair value of partnerships is determined by
aggregating the value of the underlying assets less liabilities.

Alabama Power Company 2018 Annual Report
The fair values, and actual allocations relative to the target allocations, of the Southern Company system's pension plans at
December 31, 2018 and 2017 are presented below. The fair values presented are prepared in accordance with GAAP. For purposes
of determining the fair value of the pension plan and other postretirement benefit plan assets and the appropriate level
designation, management relies on information provided by the plan's trustee. This information is reviewed and evaluated by
management with changes made to the trustee information as appropriate. The registrants did not have any investments classified
as Level 3 at December 31, 2018 or 2017.
These fair values exclude cash, receivables related to investment income and pending investment sales, and payables related to
pending investment purchases.

Stock-based compensation primarily in the form of Southern Company performance share units (PSU) and restricted stock units
(RSU) may be granted through the Omnibus Incentive Compensation Plan to a large segment of Southern Company system
employees ranging from line management to executives. Southern Company Gas and Southern Power had no employee
participants in the stock-based compensation plans until 2017 and 2018, respectively. In conjunction with the Merger, stock-based
compensation in the form of Southern Company RSUs and PSUs was granted to certain executives of Southern Company Gas
through the Southern Company Omnibus Incentive Compensation Plan.
At December 31, 2018, the number of current and former employees participating in stock-based compensation programs for the
registrants was as follows:

Number of employees
4,716

Employees become immediately vested in PSUs and RSUs upon retirement. As a result, compensation expense for employees that
are retirement eligible at the grant date is recognized immediately, while compensation expense for employees that become
retirement eligible during the vesting period is recognized over the period from grant date to the date of retirement eligibility. In
addition, the registrants recognize forfeitures as they occur.
All unvested PSUs and RSUs vest immediately upon a change in control where Southern Company is not the surviving
corporation.
Performance Share Units
PSUs granted to employees vest at the end of a three-year performance period. Shares of Southern Company common stock are
delivered to employees at the end of the performance period with the number of shares issued ranging from 0% to 200% of the
target number of PSUs granted, based on achievement of the performance goals established by the Compensation Committee of
the Southern Company Board of Directors.
Southern Company has issued three types of PSUs, each with a unique performance goal. These types of PSUs include total
shareholder return (TSR) awards based on the TSR for Southern Company common stock during the three-year performance
period as compared to a group of industry peers; ROE awards based on Southern Company's equity-weighted return over the
performance period; and EPS awards based on Southern Company's cumulative EPS over the performance period. EPS awards
were not granted in 2018.
170
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
The fair value of TSR awards is determined as of the grant date using a Monte Carlo simulation model to estimate the TSR of
Southern Company's common stock among industry peers over the performance period. In determining the fair value of the TSR
awards issued to employees, the expected volatility is based on the historical volatility of Southern Company's stock over a period
equal to the performance period. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant that
covers the performance period of the awards. The following table shows the assumptions used in the pricing model and the
weighted average grant-date fair value of TSR awards granted:
Year Ended December 31

The registrants recognize TSR award compensation expense on a straight-line basis over the three-year performance period
without remeasurement.
The fair values of EPS awards and ROE awards are based on the closing stock price of Southern Company common stock on the
date of the grant. The weighted average grant-date fair value of the awards granted during 2018, 2017, and 2016 was $43.49,
$49.21, and $48.87, respectively. Compensation expense for EPS and ROE awards is generally recognized ratably over the three-
year performance period adjusted for expected changes in EPS and ROE performance. Total compensation cost recognized for
vested EPS awards and ROE awards reflects final performance metrics.
Southern Company's total unvested PSUs outstanding at December 31, 2017 was 2.9 million. In February 2018, 1.5 million PSUs
vested for the three-year performance period ended December 31, 2017 were converted into 1.9 million shares outstanding at a
share price of $44.68.
During 2018, Southern Company granted 1.3 million PSUs and 1.9 million PSUs were vested or forfeited, resulting in 2.5 million
unvested PSUs outstanding at December 31, 2018. In February 2019, the PSUs that vested for the three-year performance period
ended December 31, 2018 were converted into 1.7 million shares outstanding at a share price of $49.24.

The compensation cost related to the grant of Southern Company PSUs to the employees of the traditional electric operating
companies, Southern Power, and Southern Company Gas is recognized in each respective registrant's financial statements with a
corresponding credit to equity representing a capital contribution from Southern Company.
At December 31, 2018, Southern Company's total unrecognized compensation cost related to PSUs was $30 million and is
expected to be recognized over a weighted-average period of approximately 16 months. The total unrecognized compensation
cost related to PSUs as of December 31, 2018 was immaterial for all other registrants.
Restricted Stock Units
Beginning in 2017, employees are granted RSUs in addition to PSUs. One-third of the RSUs granted to employees vest each year
throughout a three-year service period. Shares of Southern Company common stock are delivered to employees at the end of each
vesting period.
The fair value of RSUs is based on the closing stock price of Southern Company common stock on the date of the grant. The
weighted average grant-date fair values of RSUs granted during 2018 and 2017 were $43.81 and $49.25, respectively. Since one-
third of the RSUs vest each year throughout a three-year service period, compensation cost for RSUs is generally recognized over
the corresponding one-, two-, or three-year vesting period.
Southern Company had 0.7 million RSUs outstanding at December 31, 2017. During 2018, Southern Company granted 0.7
million RSUs and 0.3 million RSUs were vested or forfeited, resulting in 1.1 million unvested RSUs outstanding at December 31,
2018, including RSUs related to employee retention agreements.
For the years ended December 31, 2018 and 2017, Southern Company's total compensation cost for RSUs recognized in income
was $27 million and $25 million, respectively. The related tax benefit also recognized in income was $7 million and $10 million
for the years ended December 31, 2018 and 2017, respectively. Total unrecognized compensation cost related to RSUs as of
December 31, 2018 for Southern Company of $13 million will be recognized over a weighted-average period of approximately 16
months.

Total RSUs outstanding and total compensation cost and related tax benefit for the RSUs recognized in income for the years
ended December 31, 2018 and 2017, as well as the total unrecognized compensation cost as of December 31, 2018, were
immaterial for all other registrants.
Stock Options
In 2015, Southern Company discontinued granting stock options. Stock options expire no later than 10 years after the grant date
and the latest possible exercise will occur no later than November 2024. As of December 31, 2018, the weighted average
remaining contractual term for the options outstanding and exercisable was approximately 4 years.
As of December 31, 2017, all stock option awards are vested and compensation cost fully recognized. Total compensation cost for
stock option awards and the related tax benefits recognized in income for the years ended December 31, 2017 and 2016 were
immaterial for Southern Company, Alabama Power, Georgia Power, and Mississippi Power.

Alabama Power Company 2018 Annual Report
Merger Stock Compensation
At the effective time of the Merger, each share of Southern Company Gas common stock, other than certain excluded shares, was
converted into the right to receive $66 in cash, without interest. Also, at the effective time of the Merger:
•
•
•
Southern Company Gas' outstanding RSUs, restricted stock awards, and non-employee director stock awards were
deemed fully vested and were canceled and converted into the right to receive an amount in cash equal to the product of
(i) the total number of shares of Southern Company Gas' common stock subject to such award and (ii) the Merger
consideration of $66 per share;
Southern Company Gas' outstanding stock options, all of which were fully vested, were canceled and converted into the
right to receive an amount in cash equal to the product of (i) the total number of shares of Southern Company Gas'
common stock subject to such options and (ii) the excess of the Merger consideration of $66 per share over the
applicable exercise price per share of such options; and
each outstanding award of a Southern Company Gas PSU was converted into an award of Southern Company RSUs. The
conversion ratio was the product of (i) the greater of (a) 125% of the number of units underlying such award based on
target level achievement of all relevant performance goals and (b) the number of units underlying such award based on
the actual level of achievement of all relevant performance goals against target and (ii) an exchange ratio based on the
Merger consideration of $66 per share as compared to the volume-weighted average price per share of Southern
Company common stock.
Southern Company Restricted Stock Awards
At the effective time of the Merger, each outstanding award of existing Southern Company Gas PSUs was converted into an
award of Southern Company RSUs. Under the terms of the restricted stock awards, the employees received Southern Company
stock when they satisfy the requisite service period by being continuously employed through the original three-year vesting
schedule of the award being replaced. Southern Company issued 0.7 million RSUs with a grant-date fair value of $53.83, based
on the closing stock price of Southern Company common stock on the date of the grant. As a portion of the fair value of the award
related to pre-combination service, the grant date fair value was allocated to pre- or post-combination service and accounted for as
Merger consideration or compensation cost, respectively. Approximately $13 million of the grant date fair value was allocated to
Merger consideration. Southern Company Gas recognized the remaining fair value as compensation expense on a straight-line
basis over the remaining vesting period. As of December 31, 2018, all RSUs are vested and compensation cost is fully recognized.
For the years ended December 31, 2018, 2017, and 2016, total compensation cost for RSUs recognized in income was $2 million,
$8 million, and $13 million, respectively, with the related tax benefit of $1 million, $4 million, and $4 million, respectively, also
recognized in income. The compensation cost related to the grant of RSUs to Southern Company Gas employees is recognized in
Southern Company Gas' financial statements with a corresponding credit to equity, representing a capital contribution from
Southern Company.
Southern Company Gas Change in Control Awards
Southern Company awarded PSUs to certain Southern Company Gas employees who continued their employment with the
Southern Company in lieu of certain change in control benefits the employee was entitled to receive following the Merger
(change in control awards). Shares of Southern Company common stock and/or cash equal to the dollar value of the change in
control benefit will vest and be issued one-third each year as long as the employee remains in service with Southern Company or
its subsidiaries at each vest date. In addition to the change in control benefit, Southern Company common stock could be issued to
the employees at the end of a performance period based on achievement of certain Southern Company common stock price
metrics, as well performance goals established by the Compensation Committee of the Southern Company Board of Directors
(achievement shares).
The change in control benefits are accounted for as a liability award with the fair value equal to the guaranteed dollar value of the
change in control benefit. The compensation cost of the change in control benefit is recognized in Southern Company Gas'
financial statements with a corresponding credit to a liability. The grant-date fair value of the achievement portion of the award
was determined using a Monte Carlo simulation model to estimate the number of achievement shares expected to vest based on
the Southern Company common stock price. The compensation cost of the achievement shares is recognized in Southern
Company Gas' financial statements with a corresponding credit to equity, representing a capital contribution from Southern
Company. The expected payout is reevaluated annually with expense recognized to date increased or decreased proportionately
based on the expected performance. The compensation cost ultimately recognized for the achievement shares will be based on the
actual performance.

NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
For the years ended December 31, 2018, 2017, and 2016, total compensation cost for the change in control awards recognized in
income was $5 million, $12 million, and $4 million, respectively, with the related tax benefit of $2 million, $6 million, and less
than $1 million, respectively, also recognized in income. As of December 31, 2018, $2 million of total unrecognized
compensation cost related to change in control awards will be recognized over a weighted-average period of approximately six
months.
Predecessor
For the predecessor period of January 1, 2016 through June 30, 2016, the employees of Southern Company Gas and subsidiaries
participated in the AGL Resources Inc. Omnibus Performance Incentive Plan, as amended and restated.
The AGL Resources Inc. Omnibus Performance Incentive Plan, as amended and restated, and the Long-Term Incentive Plan
(1999) provided for the grant of incentive and nonqualified stock options, stock appreciation rights, shares of restricted stock,
RSUs, performance cash awards, and other stock-based awards to officers and key employees. Effective July 1, 2016, all Southern
Company Gas shares of stock were canceled and/or converted as a result of the Merger. No further grants will be made from the
Long-Term Incentive Plan (1999) or the AGL Resources Inc. Omnibus Performance Incentive Plan, as amended and restated.
For the predecessor period, Southern Company Gas recognized stock-based compensation cost for its stock-based awards over the
requisite service period based on the estimated fair value at the date of grant for its stock-based awards using the modified
prospective method.
Performance-based stock awards and performance units contained market and performance conditions. Stock options, restricted
stock awards, and performance units also contained a service condition. Southern Company Gas estimated forfeitures over the
requisite service period when recognizing compensation cost. These estimates were adjusted to the extent that actual forfeitures
differ, or were expected to materially differ, from such estimates. The difference between the proceeds from the exercise of
Southern Company Gas' stock-based awards and the par value of the stock was recorded within additional paid-in capital.
Southern Company Gas granted stock awards with a grant price that was equal to the fair market value on the date of the grant.
Fair market value was defined under the terms of the applicable plans as the closing price per share of Southern Company Gas'
common stock on the grant date. For the predecessor period of January 1, 2016 through June 30, 2016, total compensation cost for
cash and stock-based awards recognized in income was $24 million with related tax benefits of an immaterial amount also
recognized in income.
13. FAIR VALUE MEASUREMENTS
Fair value measurements are based on inputs of observable and unobservable market data that a market participant would use in
pricing the asset or liability. The use of observable inputs is maximized where available and the use of unobservable inputs is
minimized for fair value measurement and reflects a three-tier fair value hierarchy that prioritizes inputs to valuation techniques
used for fair value measurement.
• Level 1 consists of observable market data in an active market for identical assets or liabilities.
• Level 2 consists of observable market data, other than that included in Level 1, that is either directly or indirectly observable.
• Level 3 consists of unobservable market data. The input may reflect the assumptions of each registrant of what a market
participant would use in pricing an asset or liability. If there is little available market data, then each registrant's own
assumptions are the best available information.
In the case of multiple inputs being used in a fair value measurement, the lowest level input that is significant to the fair value
measurement represents the level in the fair value hierarchy in which the fair value measurement is reported.

Valuation Methodologies
The energy-related derivatives primarily consist of exchange-traded and over-the-counter financial products for natural gas and
physical power products, including, from time to time, basis swaps. These are standard products used within the energy industry
and are valued using the market approach. The inputs used are mainly from observable market sources, such as forward natural
gas prices, power prices, implied volatility, and overnight index swap interest rates. Interest rate derivatives are also standard
over-the-counter products that are valued using observable market data and assumptions commonly used by market participants.
The fair value of interest rate derivatives reflects the net present value of expected payments and receipts under the swap
181
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
agreement based on the market's expectation of future interest rates. Additional inputs to the net present value calculation may
include the contract terms, counterparty credit risk, and occasionally, implied volatility of interest rate options. The fair value of
cross-currency swaps reflects the net present value of expected payments and receipts under the swap agreement based on the
market's expectation of future foreign currency exchange rates. Additional inputs to the net present value calculation may include
the contract terms, counterparty credit risk, and discount rates. The interest rate derivatives and cross-currency swaps are
categorized as Level 2 under Fair Value Measurements as these inputs are based on observable data and valuations of similar
instruments. See Note 14 for additional information on how these derivatives are used.
For fair value measurements of the investments within the nuclear decommissioning trusts and the non-qualified deferred
compensation trusts, external pricing vendors are designated for each asset class with each security specifically assigned a
primary pricing source. For investments held within commingled funds, fair value is determined at the end of each business day
through the net asset value, which is established by obtaining the underlying securities' individual prices from the primary pricing
source. A market price secured from the primary source vendor is then evaluated by management in its valuation of the assets
within the trusts. As a general approach, fixed income market pricing vendors gather market data (including indices and market
research reports) and integrate relative credit information, observed market movements, and sector news into proprietary pricing
models, pricing systems, and mathematical tools. Dealer quotes and other market information, including live trading levels and
pricing analysts' judgments, are also obtained when available.
The NRC requires licensees of commissioned nuclear power reactors to establish a plan for providing reasonable assurance of
funds for future decommissioning. See Note 6 under "Nuclear Decommissioning" for additional information.
Southern Power has contingent payment obligations related to certain acquisitions whereby Southern Power is primarily obligated
to make generation-based payments to the seller, which commenced at the commercial operation of the respective facility and
continue through 2026. The obligation is categorized as Level 3 under Fair Value Measurements as the fair value is determined
using significant unobservable inputs for the forecasted facility generation in MW-hours, as well as other inputs such as a fixed
dollar amount per MW-hour, and a discount rate. The fair value of contingent consideration reflects the net present value of
expected payments and any periodic change arising from forecasted generation is expected to be immaterial.
"Other investments" include investments categorized as Level 3 under Fair Value Measurements that are not traded in the open
market. The fair value of these investments has been determined based on market factors including comparable multiples and the
expectations regarding cash flows and business plan executions.
The fair value measurements of private equity investments held in Alabama Power's nuclear decommissioning trusts that are
calculated at net asset value per share (or its equivalent) as a practical expedient totaled $45 million and $29 million at
December 31, 2018 and 2017, respectively. Unfunded commitments related to the private equity investments totaled $50 million
and $21 million at December 31, 2018 and 2017, respectively. Private equity funds include funds-of-funds that invest in high-
quality private equity funds across several market sectors, funds that invest in real estate assets, and a fund that acquires
companies to create resale value. Private equity funds do not have redemption rights. Distributions from these funds will be
received as the underlying investments in the funds are liquidated.

The fair values are determined using Level 2 measurements and are based on quoted market prices for the same or similar issues
or on the current rates available to the registrants.
14. DERIVATIVES
Southern Company, the traditional electric operating companies, Southern Power, and Southern Company Gas are exposed to
market risks, including commodity price risk, interest rate risk, weather risk, and occasionally foreign currency exchange rate
risk. To manage the volatility attributable to these exposures, each company nets its exposures, where possible, to take advantage
of natural offsets and enters into various derivative transactions for the remaining exposures pursuant to each company's policies
in areas such as counterparty exposure and risk management practices. Southern Company Gas' wholesale gas operations use
various contracts in its commercial activities that generally meet the definition of derivatives. For the traditional electric operating
companies, Southern Power, and Southern Company Gas' other businesses, each company's policy is that derivatives are to be
used primarily for hedging purposes and mandates strict adherence to all applicable risk management policies. Derivative
positions are monitored using techniques including, but not limited to, market valuation, value at risk, stress testing, and
sensitivity analysis. Derivative instruments are recognized at fair value in the balance sheets as either assets or liabilities and are
presented on a net basis. See Note 13 for additional fair value information. In the statements of cash flows, any cash impacts of
settled energy-related and interest rate derivatives are recorded as operating activities. Any cash impacts of settled foreign
currency derivatives are classified as operating or financing activities to correspond with classification of the hedged interest or
principal, respectively. See Note 1 under "Financial Instruments" for additional information.
The registrants adopted ASU 2017-12 as of January 1, 2018. See Note 1 under "Recently Adopted Accounting Standards – Other"
for additional information.
Energy-Related Derivatives
The traditional electric operating companies, Southern Power, and Southern Company Gas enter into energy-related derivatives to
hedge exposures to electricity, natural gas, and other fuel price changes. However, due to cost-based rate regulations and other
various cost recovery mechanisms, the traditional electric operating companies and the natural gas distribution utilities have
limited exposure to market volatility in energy-related commodity prices. Each of the traditional electric operating companies and
certain of the natural gas distribution utilities of Southern Company Gas manage fuel-hedging programs, implemented per the
guidelines of their respective state PSCs or other applicable state regulatory agencies, through the use of financial derivative
contracts, which are expected to continue to mitigate price volatility. The traditional electric operating companies (with respect to
wholesale generating capacity) and Southern Power have limited exposure to market volatility in energy-related commodity
prices because their long-term sales contracts shift substantially all fuel cost responsibility to the purchaser. However, the
traditional electric operating companies and Southern Power may be exposed to market volatility in energy-related commodity

prices to the extent any uncontracted capacity is used to sell electricity. Southern Company Gas retains exposure to price changes
that can, in a volatile energy market, be material and can adversely affect its results of operations.
Southern Company Gas also enters into weather derivative contracts as economic hedges of operating margins in the event of
warmer-than-normal weather. Exchange-traded options are carried at fair value, with changes reflected in operating revenues.
Non-exchange-traded options are accounted for using the intrinsic value method. Changes in the intrinsic value for non-exchange-
traded contracts are reflected in operating revenues.
Energy-related derivative contracts are accounted for under one of three methods:
• Regulatory Hedges – Energy-related derivative contracts designated as regulatory hedges relate primarily to the traditional
electric operating companies' and the natural gas distribution utilities' fuel-hedging programs, where gains and losses are
initially recorded as regulatory liabilities and assets, respectively, and then are included in fuel expense as the underlying fuel
is used in operations and ultimately recovered through the respective fuel cost recovery clauses.
• Cash Flow Hedges – Gains and losses on energy-related derivatives designated as cash flow hedges (which are mainly used
to hedge anticipated purchases and sales) are initially deferred in AOCI before being recognized in the statements of income
in the same period and in the same income statement line item as the earnings effect of the hedged transactions.
• Not Designated – Gains and losses on energy-related derivative contracts that are not designated or fail to qualify as hedges
are recognized in the statements of income as incurred.
Some energy-related derivative contracts require physical delivery as opposed to financial settlement, and this type of derivative
is both common and prevalent within the electric and natural gas industries. When an energy-related derivative contract is settled
physically, any cumulative unrealized gain or loss is reversed and the contract price is recognized in the respective line item
representing the actual price of the underlying goods being delivered.
At December 31, 2018, the net volume of energy-related derivative contracts for natural gas positions, together with the longest
hedge date over which the respective entity is hedging its exposure to the variability in future cash flows for forecasted
transactions and the longest non-hedge date for derivatives not designated as hedges, were as follows:

(*) Southern Company Gas' derivative instruments include both long and short natural gas positions. A long position is a contract to purchase natural gas and a
short position is a contract to sell natural gas. Southern Company Gas' volume represents the net of long natural gas positions of 4,159 million mmBtu and
short natural gas positions of 4,039 million mmBtu at December 31, 2018, which is also included in Southern Company's total volume.
At December 31, 2018, the net volume of Southern Power's energy-related derivative contracts for power to be sold was 2 million
MWHs, all of which expire by 2020.
In addition to the volumes discussed above, the traditional electric operating companies and Southern Power enter into physical
natural gas supply contracts that provide the option to sell back excess natural gas due to operational constraints. The maximum
expected volume of natural gas subject to such a feature is 23 million mmBtu for Southern Company, which includes 4 million
mmBtu for Alabama Power, 7 million mmBtu for Georgia Power, 3 million mmBtu for Mississippi Power, and 7 million mmBtu
for Southern Power.
For cash flow hedges of energy-related derivatives, the estimated pre-tax gains (losses) expected to be reclassified from AOCI to
earnings for the year ending December 31, 2019 are immaterial for all registrants.
Interest Rate Derivatives
Southern Company and certain subsidiaries may enter into interest rate derivatives to hedge exposure to changes in interest rates.
The derivatives employed as hedging instruments are structured to minimize ineffectiveness. Derivatives related to existing
184
NOTES TO FINANCIAL STATEMENTS (continued)

variable rate securities or forecasted transactions are accounted for as cash flow hedges where the derivatives' fair value gains or
losses are recorded in OCI and are reclassified into earnings at the same time and presented on the same income statement line
item as the earnings effect of the hedged transactions. Derivatives related to existing fixed rate securities are accounted for as fair
value hedges, where the derivatives' fair value gains or losses and hedged items' fair value gains or losses are both recorded
directly to earnings on the same income statement line item. Fair value gains or losses on derivatives that are not designated or
fail to qualify as hedges are recognized in the statements of income as incurred.

The estimated pre-tax gains (losses) related to interest rate derivatives expected to be reclassified from AOCI to interest expense

gains and losses related to interest rate derivatives are expected to be amortized into earnings through 2046 for the Southern
Company parent entity, 2035 for Alabama Power, 2037 for Georgia Power, 2028 for Mississippi Power, and 2046 for Southern
Company Gas.
Foreign Currency Derivatives
Southern Company and certain subsidiaries, including Southern Power, may enter into foreign currency derivatives to hedge
exposure to changes in foreign currency exchange rates, such as that arising from the issuance of debt denominated in a currency
other than U.S. dollars. Derivatives related to forecasted transactions are accounted for as cash flow hedges where the derivatives'
fair value gains or losses are recorded in OCI and are reclassified into earnings at the same time and on the same income
statement line as the earnings effect of the hedged transactions, including foreign currency gains or losses arising from changes in
the U.S. currency exchange rates. The derivatives employed as hedging instruments are structured to minimize ineffectiveness.

Derivative Financial Statement Presentation and Amounts
Southern Company, the traditional electric operating companies, Southern Power, and Southern Company Gas enter into
derivative contracts that may contain certain provisions that permit intra-contract netting of derivative receivables and payables
for routine billing and offsets related to events of default and settlements. Southern Company and certain subsidiaries also utilize
master netting agreements to mitigate exposure to counterparty credit risk. These agreements may contain provisions that permit
netting across product lines and against cash collateral. The fair value amounts of derivative assets and liabilities on the balance
sheets are presented net to the extent that there are netting arrangements or similar agreements with the counterparties.
At December 31, 2018 and 2017, the fair value of energy-related derivatives, interest rate derivatives, and foreign currency
derivatives was reflected in the balance sheets as follows:

(*) Excludes the impact of weather derivatives recorded in natural gas revenues of $5 million and $23 million for the successor years ended December 31, 2018
and 2017, respectively, $6 million for the successor period of July 1, 2016 through December 31, 2016, and $3 million for the predecessor period of January 1,
2016 through June 30, 2016, as they are accounted for based on intrinsic value rather than fair value.
The pre-tax effects of energy-related derivatives and interest rate derivatives not designated as hedging instruments were
immaterial for all other registrants for all years presented.
Contingent Features
Southern Company, the traditional electric operating companies, Southern Power, and Southern Company Gas do not have any
credit arrangements that would require material changes in payment schedules or terminations as a result of a credit rating
downgrade. There are certain derivatives that could require collateral, but not accelerated payment, in the event of various credit
rating changes of certain Southern Company subsidiaries. At December 31, 2018, the registrants had no collateral posted with
derivative counterparties to satisfy these arrangements.
For the registrants with interest rate derivatives at December 31, 2018, the fair value of interest rate derivative liabilities with
contingent features and the maximum potential collateral requirements arising from the credit-risk-related contingent features, at a
rating below BBB- and/or Baa3, was immaterial. At December 31, 2018, the fair value of energy-related derivative liabilities with
contingent features and the maximum potential collateral requirements arising from the credit-risk-related contingent features, at a
rating below BBB- and/or Baa3, were immaterial for all registrants. The maximum potential collateral requirements arising from
the credit-risk-related contingent features for the traditional electric operating companies and Southern Power include certain
agreements that could require collateral in the event that one or more Southern Company power pool participants has a credit
rating change to below investment grade. Following the sale of Gulf Power to NextEra Energy, Gulf Power is continuing to
participate in the Southern Company power pool for a defined transition period that, subject to certain potential adjustments, is
scheduled to end on January 1, 2024.
Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. If collateral is required, fair value
amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral are not offset against fair
value amounts recognized for derivatives executed with the same counterparty.
Alabama Power and Southern Power maintain accounts with certain regional transmission organizations to facilitate financial
derivative transactions. Based on the value of the positions in these accounts and the associated margin requirements, Alabama
Power and Southern Power may be required to post collateral. At December 31, 2018, cash collateral posted in these accounts was
immaterial. Southern Company Gas maintains accounts with brokers or the clearing houses of certain exchanges to facilitate
financial derivative transactions. Based on the value of the positions in these accounts and the associated margin requirements,
Southern Company Gas may be required to deposit cash into these accounts. At December 31, 2018, cash collateral held on
deposit in broker margin accounts was $277 million.
The registrants are exposed to losses related to financial instruments in the event of counterparties' nonperformance. The
registrants only enter into agreements and material transactions with counterparties that have investment grade credit ratings by
Moody's and S&P or with counterparties who have posted collateral to cover potential credit exposure. The registrants have also
established risk management policies and controls to determine and monitor the creditworthiness of counterparties in order to
mitigate their exposure to counterparty credit risk. Prior to entering into a physical transaction, Southern Company Gas assigns
physical wholesale counterparties an internal credit rating and credit limit based on the counterparties' Moody's, S&P, and Fitch
ratings, commercially available credit reports, and audited financial statements. Southern Company Gas may require
counterparties to pledge additional collateral when deemed necessary.
194
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
In addition, Southern Company Gas conducts credit evaluations and obtains appropriate internal approvals for the counterparty's
line of credit before any transaction with the counterparty is executed. In most cases, the counterparty must have an investment
grade rating, which includes a minimum long-term debt rating of Baa3 from Moody's and BBB- from S&P. Generally, Southern
Company Gas requires credit enhancements by way of a guaranty, cash deposit, or letter of credit for transaction counterparties
that do not have investment grade ratings.
Southern Company Gas also utilizes master netting agreements whenever possible to mitigate exposure to counterparty credit
risk. When Southern Company Gas is engaged in more than one outstanding derivative transaction with the same counterparty
and it also has a legally enforceable netting agreement with that counterparty, the "net" mark-to-market exposure represents the
netting of the positive and negative exposures with that counterparty and a reasonable measure of Southern Company Gas' credit
risk. Southern Company Gas also uses other netting agreements with certain counterparties with whom it conducts significant
transactions. Master netting agreements enable Southern Company Gas to net certain assets and liabilities by counterparty.
Southern Company Gas also nets across product lines and against cash collateral provided the master netting and cash collateral
agreements include such provisions. Southern Company Gas may require counterparties to pledge additional collateral when
deemed necessary.
The registrants do not anticipate a material adverse effect on their respective financial statements as a result of counterparty
nonperformance.
15. ACQUISITIONS AND DISPOSITIONS
Southern Company Merger with Southern Company Gas
On July 1, 2016, Southern Company completed the Merger for a total purchase price of approximately $8.0 billion and Southern
Company Gas became a wholly-owned, direct subsidiary of Southern Company. At the effective time of the Merger, each share of
Southern Company Gas common stock, other than certain excluded shares, was converted into the right to receive $66 in cash,
without interest. Also at the effective time of the Merger, all of the outstanding Southern Company Gas RSUs, restricted stock
awards, non-employee director stock awards, stock options, and PSUs were either redeemed or converted into Southern Company
RSUs. See Note 12 for additional information.
The application of the acquisition method of accounting was pushed down to Southern Company Gas. The excess of the purchase
price over the fair values of Southern Company Gas' assets and liabilities was recorded as goodwill, which represents a different
basis of accounting from Southern Company Gas' historical basis prior to the Merger. The following table presents the final
purchase price allocation:

(b) In November 2018, Southern Power entered into an agreement to sell all of its equity interests in Plant Mankato, including this expansion currently under
construction. See "Sales of Natural Gas Plants" below.
(c) In May 2018, Southern Power purchased 100% of the Wild Horse Mountain facility. Southern Power may enter into a tax equity partnership, in which case it
would then own 100% of the class B membership interests. The ultimate outcome of this matter cannot be determined at this time.
(d) In August 2018, Southern Power purchased 100% of the membership interests of the Reading facility from the joint development arrangement with
Renewable Energy Systems Americas, Inc. described below. Southern Power may enter into a tax equity partnership, in which case it would then own 100%
of the class B membership interests. The ultimate outcome of this matter cannot be determined at this time.
Development Projects
During 2017, Southern Power purchased wind turbine equipment to be used for various development and construction projects.
Any wind projects using this equipment and reaching commercial operation by the end of 2021 are expected to qualify for 80%
PTCs.
During 2016, Southern Power entered into a joint development agreement with Renewable Energy Systems Americas, Inc. (RES)
to develop and construct wind projects. Concurrent with the agreement, Southern Power purchased wind turbine equipment from
Siemens Wind Power, Inc. and Vestas-American Wind Technology, Inc. to be used for construction of these projects. Several wind
projects using this equipment, as well as other purchased equipment, have successfully originated, directly or indirectly, from the
partnership with RES and are expected to reach commercial operation before the end of 2020, thus qualifying for 100% PTCs.
Southern Power continues to evaluate and refine the deployment of the wind turbine equipment to potential joint development and
construction projects as well as the amount of MW capacity to be constructed. During the third quarter 2018, as a result of a
review of various options for probable dispositions of wind turbine equipment not deployed to development or construction
projects, Southern Power recorded a $36 million asset impairment charge on the equipment.
Subsequent to December 31, 2018 and as part of management's continuous review of disposition options, approximately $53
million of this equipment is being marketed for sale and will be classified as held for sale.
The ultimate outcome of these matters cannot be determined at this time.
Sales of Renewable Facility Interests
On May 22, 2018, Southern Power completed the sale of a noncontrolling 33% equity interest in SP Solar, a limited partnership
indirectly owning substantially all of Southern Power's solar facilities, to Global Atlantic for approximately $1.2 billion. Since
Southern Power retains control of the limited partnership through its wholly-owned general partner, the sale was recorded as an
198
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
equity transaction and Southern Power will continue to consolidate SP Solar in its financial statements. On the date of the
transaction, the noncontrolling interest was increased by $511 million to reflect 33% of the carrying value of the partnership. This
difference, partially offset by the tax impact and other related transaction charges, also resulted in a $410 million decrease to
Southern Power's common stockholder's equity.
On December 11, 2018, Southern Power completed the sale of a noncontrolling tax equity interest in SP Wind, which owns a
portfolio of eight operating wind facilities, to three financial investors for approximately $1.2 billion. Since Southern Power
retains control of SP Wind, it will continue to consolidate SP Wind in its financial statements. The tax equity investors together
will generally receive 40% of the cash distributions from available cash and will receive a 99% allocation of tax attributes,
including future PTCs.
Sales of Natural Gas Plants
On December 4, 2018, Southern Power completed the sale of all of its equity interests in the Florida Plants to NextEra Energy for
$203 million. In contemplation of this sale transaction, Southern Power recorded an asset impairment charge of approximately
$119 million ($89 million after tax) in May 2018.
On November 5, 2018, Southern Power entered into an agreement with Northern States Power to sell all of its equity interests in
Plant Mankato (including the 385-MW expansion currently under construction) for an aggregate purchase price of approximately
$650 million. The completion of the disposition is subject to the expansion unit reaching commercial operation as well as various
other customary conditions to closing, including working capital and timing adjustments. The ultimate purchase price will
decrease $66,667 per day for each day after June 1, 2019 that the expansion has not achieved commercial operation, not to exceed
$15 million. This transaction is subject to FERC and state commission approvals and is expected to close in mid-2019. The assets
and liabilities of Plant Mankato are classified as assets held for sale and liabilities held for sale on Southern Company's and
Southern Power's balance sheet as of December 31, 2018. See "Assets Held for Sale" herein for additional information. The
ultimate outcome of this matter cannot be determined at this time.
Southern Company Gas
See "Southern Company Merger with Southern Company Gas" herein for information regarding the Merger.
Investment in SNG
In 2016, Southern Company Gas, through a wholly-owned, indirect subsidiary, acquired a 50% equity interest in SNG from
Kinder Morgan, Inc. for $1.4 billion. SNG owns a 7,000-mile pipeline system connecting natural gas supply basins in Texas,
Louisiana, Mississippi, and Alabama to markets in Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina, and
Tennessee. The purchase price exceeded the underlying ownership interest in the net assets of SNG by approximately $700
million. This basis difference was attributable to goodwill and deferred tax assets. While the deferred tax assets will be amortized
through deferred tax expense, the goodwill will not be amortized and is not required to be tested for impairment on an annual
basis.
In March 2017, Southern Company Gas made an additional $50 million contribution to maintain its 50% equity interest in SNG.
See Note 7 under "Southern Company Gas" for additional information on this investment.
Southern Company Gas' investment in SNG decreased by $104 million at December 31, 2017 related to the impact of the Tax
Reform Legislation and new income tax apportionment factors in several states resulting from Southern Company Gas' inclusion
in the consolidated Southern Company state tax filings.
Sale of Pivotal Home Solutions
On June 4, 2018, Southern Company Gas completed the stock sale of Pivotal Home Solutions to American Water Enterprises LLC
for a total cash purchase price of $365 million, which includes the final working capital adjustment. This disposition resulted in a
net loss of $67 million, which includes $34 million of income tax expense. In contemplation of the transaction, a goodwill
impairment charge of $42 million was recorded during the first quarter 2018. The income tax expense included tax on goodwill
not deductible for tax purposes and for which a deferred tax liability had not been recorded previously. Southern Company Gas
and American Water Enterprises LLC entered into a transition services agreement whereby Southern Company Gas provided
certain administrative and operational services through November 4, 2018.
Sale of Elizabethtown Gas and Elkton Gas
On July 1, 2018, a Southern Company Gas subsidiary, Pivotal Utility Holdings, completed the sales of the assets of two of its
natural gas distribution utilities, Elizabethtown Gas and Elkton Gas, to South Jersey Industries, Inc. for a total cash purchase price
199
NOTES TO FINANCIAL STATEMENTS (continued)
Alabama Power Company 2018 Annual Report
of $1.7 billion, which includes the final working capital and other adjustments. This disposition resulted in a pre-tax gain that was
entirely offset by $205 million of income tax expense, resulting in no material net income impact. The income tax expense
included tax on goodwill not deductible for tax purposes and for which a deferred tax liability had not been recorded previously.
Southern Company Gas and South Jersey Industries, Inc. entered into transition services agreements whereby Southern Company
Gas will provide certain administrative and operational services through no later than July 31, 2020.
Sale of Florida City Gas
On July 29, 2018, Southern Company Gas and its wholly-owned direct subsidiary, NUI Corporation, completed the stock sale of
Pivotal Utility Holdings, which primarily consisted of Florida City Gas, to NextEra Energy for a total cash purchase price of $587
million, which includes the final working capital adjustment. This disposition resulted in a net gain of $16 million, which includes
$103 million of income tax expense. The income tax expense included tax on goodwill not deductible for tax purposes and for
which a deferred tax liability had not been recorded previously. Southern Company Gas and NextEra Energy entered into a
transition services agreement whereby Southern Company Gas will provide certain administrative and operational services
through no later than July 29, 2020.
Assets Held for Sale
As discussed previously, Southern Company and Southern Power each have assets and liabilities held for sale on their balance
sheets at December 31, 2018. Assets and liabilities held for sale have been classified separately on each company's balance sheet
at the lower of carrying value or fair value less costs to sell at the time the criteria for held-for-sale classification were met. For
assets and liabilities held for sale recorded at fair value on a nonrecurring basis, the fair value of assets held for sale is based
primarily on unobservable inputs (Level 3), which includes the agreed upon sales prices in executed sales agreements.
Upon classification as held for sale in May 2018 for the Florida Plants and November 2018 for Plant Mankato, Southern Power
ceased recognizing depreciation on the property, plant, and equipment to be sold. The Florida Plants sale was completed on
December 4, 2018. Since the depreciation of the assets sold in the Gulf Power transaction continued to be reflected in customer
rates through the closing date and was reflected in the carryover basis of the assets when sold, Southern Company continued to
record depreciation on those assets through the date the transaction closed. Likewise, since the depreciation of the assets sold in
the Elizabethtown Gas, Elkton Gas, and Florida City Gas transactions continued to be reflected in customer rates and was
reflected in the carryover basis of the assets when sold, Southern Company Gas continued to record depreciation on those assets
through the respective date that each transaction closed.
The following table provides Southern Company's and Southern Power's major classes of assets and liabilities classified as held
for sale at December 31, 2018:

Southern Company, Southern Power, and Southern Company Gas each concluded that the asset sales, both individually and
combined, did not represent a strategic shift in operations that has, or is expected to have, a major effect on its operations and
financial results; therefore, none of the assets related to the sales have been classified as discontinued operations for any of the
periods presented.

16. SEGMENT AND RELATED INFORMATION
Southern Company
The primary businesses of the Southern Company system are electricity sales by the traditional electric operating companies and
Southern Power and the distribution of natural gas by Southern Company Gas. The traditional electric operating companies –
Alabama Power, Georgia Power, Gulf Power (through December 31, 2018), and Mississippi Power – are vertically integrated
utilities providing electric service in four Southeastern states. On January 1, 2019, Southern Company completed its sale of Gulf
Power to NextEra Energy. Southern Power develops, constructs, acquires, owns, and manages power generation assets, including
renewable energy projects, and sells electricity at market-based rates in the wholesale market. Southern Company Gas distributes
natural gas through its natural gas distribution utilities and is involved in several other complementary businesses including gas
pipeline investments, wholesale gas services, and gas marketing services. In July 2018, Southern Company Gas completed sales
of three of its natural gas distribution utilities. See Note 15 for additional information regarding disposition activities.
Southern Company's reportable business segments are the sale of electricity by the traditional electric operating companies, the
sale of electricity in the competitive wholesale market by Southern Power, and the sale of natural gas and other complementary
products and services by Southern Company Gas. Revenues from sales by Southern Power to the traditional electric operating
companies were $435 million, $392 million, and $419 million in 2018, 2017, and 2016, respectively. Revenues from sales of
natural gas from Southern Company Gas to the traditional electric operating companies and Southern Power were $32 million and
$119 million, respectively, in 2018, $23 million and $119 million, respectively, in 2017, and $11 million and $17 million,
respectively, in 2016. The "All Other" column includes the Southern Company parent entity, which does not allocate operating
expenses to business segments. Also, this category includes segments below the quantitative threshold for separate disclosure.
These segments include providing energy technologies and services to electric utilities and large industrial, commercial,
institutional, and municipal customers, as well as investments in telecommunications and leveraged lease projects. All other inter-
segment revenues are not material.

Southern Company Gas
Southern Company Gas manages its business through four reportable segments - gas distribution operations, gas pipeline
investments, wholesale gas services, and gas marketing services. The non-reportable segments are combined and presented as all
other. During 2018, Southern Company Gas changed its reportable segments to further align the way its new Chief Operating
Decision Maker reviews operating results and has reclassified prior years' data to conform to the new reportable segment
presentation. This change resulted in a new reportable segment, gas pipeline investments, which was formerly included in gas
midstream operations.
Gas distribution operations is the largest component of Southern Company Gas' business and includes natural gas local
distribution utilities that construct, manage, and maintain intrastate natural gas pipelines and gas distribution facilities in four
states. In July 2018, Southern Company Gas sold three of its natural gas distribution utilities, Elizabethtown Gas, Elkton Gas, and
Florida City Gas. See Note 15 under "Southern Company Gas" for additional information.
Gas pipeline investments consists of joint ventures in natural gas pipeline investments including a 50% interest in SNG, two
significant pipeline construction projects, and a 50% joint ownership interest in the Dalton Pipeline. These natural gas pipelines
enable the provision of diverse sources of natural gas supplies to the customers of Southern Company Gas. See Notes 5 and 7 for
additional information.
Wholesale gas services provides natural gas asset management and/or related logistics services for each of Southern Company
Gas' utilities except Nicor Gas as well as for non-affiliated companies. Additionally, wholesale gas services engages in natural gas
storage and gas pipeline arbitrage and related activities.
Gas marketing services provides natural gas marketing to end-use customers primarily in Georgia and Illinois through SouthStar.
On June 4, 2018, Southern Company Gas sold Pivotal Home Solutions, which provided home equipment protection products and
services. See Note 15 under "Southern Company Gas – Sale of Pivotal Home Solutions" for additional information.
The all other column includes segments below the quantitative threshold for separate disclosure, including the storage and fuels
operations, which was formerly included in gas midstream operations, and the other subsidiaries that fall below the quantitative
threshold for separate disclosure.
After the Merger, Southern Company Gas changed the segment performance measure to net income, which is utilized by its
parent company. In order to properly assess net income by segment, Southern Company Gas executed various intercompany note
agreements to revise interest charges to its segments. Since such agreements did not exist in the predecessor period, Southern
Company Gas is unable to provide the comparable net income for that period.
