To Our Valued Shareholders:
2017 was another year fi lled with many successes
for IDACORP, Inc., highlighted by achieving a 10th
consecutive year of earnings growth. IDACORP
provided a 15 percent cumulative annual total
shareholder return over the past three years, including
share price appreciation and dividends paid, ranking
in the 85th percentile among peer companies in the
Edison Electric Institute Electric Utilities Index.
A contributing factor in this return has been increases
in IDACORP’s quarterly common stock dividend,
which has increased 97 percent since 2011, most
recently from $0.55 to $0.59 per share.
A signifi cant driver of increased earnings has been
customer growth at Idaho Power, IDACORP’s
principal operating subsidiary. Idaho Power’s
customer count grew by 2.0 percent from 2016 to 2017,
and sales volumes to industrial customers increased
3.2 percent over the same period.
We have continued to focus on productive
regulatory outcomes, such as Idaho Power’s process
established with the Idaho and Oregon public utilities
commissions to end its participation in coal-fi red
operations at the North Valmy power plant units 1
and 2 in 2019 and 2025, respectively. In addition,
we kept other operations and maintenance expenses
relatively fl at for the sixth consecutive year.
At the same time, Idaho Power has continued to
focus on customer satisfaction, ranking second in
J.D. Power’s Electric Business Customer Satisfaction
Study for the West Midsize segment. We continue to
manage our environmental impact by achieving and

extending our CO emissions intensity reduction goal,
resulting in coal accounting for less of our total energy
supply. Coal accounted for just 18 percent of Idaho
Power’s total power supply in 2017—down from
24 percent in 2016.
At IDACORP, we are focused on the future. Our four-part
strategy focuses fi rst on growth to enhance our fi nancial
strength. We have increased our business development
eff orts, and we expect those increases to bring additional
load growth to Idaho Power over the next few years.
We are committed to exploring new revenue
opportunities, and we foresee opportunities for Idaho
Power to provide behind-the-meter services and
solutions. We will continue to promote and engage
in electrifi cation, such as leveraging electric vehicle
partnerships and making progress toward electrifying
third-party vehicle and equipment fl eets.
Th e second part of our strategy focuses on improving
the core business. We will continue to upgrade our
infrastructure for growth, technology changes, renewable
energy integration and fl exibility by achieving milestones
associated with large projects and executing on capital
projects highlighted in our most recent Integrated
Resource Plan. With eff orts such as joining the Western
Energy Imbalance Market, we will further work to
optimize wholesale transmission and energy sales. We
are committed to operating effi ciently and controlling
expenditures. We are executing our plans to use
technology, such as data analytics and security programs,
to enhance our grid, system reliability and safety. And
we continue to focus on implementing rate structures
that are fair and reasonable to all customers, such as
ensuring potential cost reductions resulting from the
Tax Cuts and Jobs Act are passed along to customers.
Th e third focus of our strategy is to enhance Idaho
Power’s brand. We recognize that our customers want
choices and transparency. We want our customers
to see us as their trusted energy advisor and to feel
that they matter to Idaho Power. We are focusing
on enhancing our customers’ experience and
interactions through simplifi cation, transparency and
targeted communications. We also believe continued
environmental stewardship, emission reductions
and constructive regulatory relationships serve to
enhance our brand in the eyes of all customers.
Th e fi nal part of our strategy, which encompasses
everything we do, maintains a focus on safety and
employee engagement.
We understand our unique role in the communities we
serve as energy advisors and environmental stewards.
We are adapting to technological changes through our
customer-owned generation regulatory fi ling in Idaho
to provide clarity and fairness in response to how all
customers choose to utilize the energy grid, as well as
utilizing cost-eff ective, innovative battery storage and
end-of-feeder solar solutions in parts of our service
area. We are committed to managing our impact on
the environment by continuing our excellent track
record of stewardship, such as the Bayha Island
research project, the Hells Canyon relicensing process
and continuing our glide path away from coal.
We believe in our strategy, and we thank you for your
continued investment in IDACORP as you join us
on our journey to achieve our mission and prosper
by providing reliable, responsible, fair-priced energy
services, today and tomorrow.

In 2017, IDACORP enjoyed a year fi lled with growth and success. Our primary subsidiary, Idaho
Power, continued to benefi t from economic development across southern Idaho and eastern
Oregon while serving more customers than ever before.
2017 marked our 10th consecutive year of earnings growth. Customer growth of 2.0 percent
increased general business revenue $12.1 million in 2017 compared with 2016. Net income
increased $14.1 million.
Low-cost energy continued to attract new customers to Idaho Power’s service area. In August,
Bloomberg named Idaho as the top performing economy in the nation. Idaho also ranked
No. 6 on CNBC’s recent list of “America’s 10 cheapest states to live in 2017,” which used a variety
of factors to calculate a cost of living score. One of those factors was the average cost of residents’
monthly energy bills — Idaho had the second-lowest rates on that list.
We fi nished the year with under $350 million of O&M expenses, putting us
near the $350 million mark for the sixth year in a row. Our eff orts to control
costs continue to pay off for the company, its customers and its shareholders.
Guidance
2017 ended with earnings of $4.21 per diluted share. On Feb. 22, 2018,
we initiated earnings guidance for the full year 2018 in the range of $4.10
to $4.25 per diluted share.

Dividend Growth
IDACORP continued to advance toward the upper end of its target dividend payout ratio of
between 50 and 60 percent of sustainable IDACORP earnings, which expanded on progress
made in previous years.
From 2011 through 2017, IDACORP's board of directors approved a collective 97 percent INCREASE
in the quarterly dividend, from $0.30 to $0.59 per share. In 2017, we increased IDACORP's quarterly
common stock dividend from $0.55 per share to $0.59 per share. We are committed to recommending
future dividend growth of at least 5 percent or more to the board of directors until we reach the upper
end of our 50-to-60 percent targeted payout ratio.
97%
Capital Expenditures
Idaho Power continues to enhance its utility infrastructure. Noteworthy ongoing capital
projects include upgrading aging assets and generation plants, replacing underground conductor
and continuing to advance the Boardman to Hemingway and Gateway West 500-kV transmission
projects. Idaho Power estimates total capital expenditures of nearly $1.5 billion over the next
fi ve years.
Th ese infrastructure investments help Idaho Power ensure an adequate supply of electricity,
provide service to new customers and maintain system reliability. In 2018, we expect capital
expenditures to be relatively consistent with 2017, with an estimated range of $280 million
to $290 million.

A Diverse Resource Portfolio
Idaho Power's hydroelectric facilities comprise nearly half of our nameplate generation capacity.
Customers are served by 17 dams on the Snake River and its tributaries, as well as three natural gas-fi red
power plants and three coal-fi red plants in which Idaho Power is part-owner. Th e graphs on this page
break down the company’s resource portfolio mix.
Idaho Power continues to work toward renewing a long-term federal license for the three-dam Hells Canyon
Complex, the company’s largest generation resource. In late 2017, the company reached a tentative settlement
with IPUC staff calling for approximately $216.5 million in expenditures related to the relicensing of the
Hells Canyon Complex to be designated as reasonable and eligible to be recovered in a future
rate case. Th e settlement is pending fi nal approval by the IPUC as of the printing of this report.

Renewables and PURPA
Idaho Power has contracts for the purchase of
power from both cogeneration and small power
production (CSPP) and non-CSPP renewable
generation sources such as biomass, wind, solar,
small hydroelectric projects and two geothermal
projects. Idaho Power purchases wind power
from both CSPP and non-CSPP facilities,
including its largest non-CSPP wind power
project — the Elkhorn Valley wind project
with a 101 MW nameplate capacity.
As of Dec. 31, 2017, Idaho Power had contracts to
purchase energy from 127 on-line CSPP projects,
one biomass project expected to come on-line in
2018 and four solar projects scheduled to come
on-line in 2019.

Social and Environmental Responsibility
Reducing CO2 emissions continues to be a goal
for Idaho Power. Th e company exceeded its CO2
emissions reduction goals in 2017, with both total
emissions and emissions intensity reaching new
lows. Th e company’s diverse generation portfolio
and long-term resource planning point toward
continued CO2 emissions reductions in the future.
In addition, Idaho Power employees continued
to practice good environmental stewardship in
2017. Examples include the ongoing Bayha Island
research project; work to boost anadromous fi sh
populations and protect birds of prey; and two
line crews who demonstrated their commitment
to the environment by rescuing a honeybee
colony near Twin Falls and a young osprey at
Swan Falls Dam.

2017 Integrated Resource Plan
Idaho Power plans for infrastructure that will support anticipated growth and allow us to continue to provide
reliable, responsible, fair-priced energy to our customers. Every two years, Idaho Power updates its Integrated
Resource Plan (IRP) with the participation of the IRP Advisory Council.
Th e 2017 IRP was fi led with state regulators in June. Key action items identifi ed in the IRP include continued
planning for participation in the Western Energy Imbalance Market (EIM), planning and coordinating with
our operating partners for early retirement of some coal-fi red units and pre-construction activities for the
Boardman to Hemingway 500-kilovolt transmission line.
HEMINGWAY SUBSTATION
500-kilovolt Transmission Projects
Th e Boardman to Hemingway Transmission Line Project reached a major milestone in November 2017,
as the Bureau of Land Management (BLM) released its Record of Decision for the proposed 300-mile,
500-kV transmission line that will run from southern Idaho to northeast Oregon. Th e project continues
to move forward, with an anticipated in-service date of 2025 or beyond.
Th e Gateway West project also progressed in 2017. Federal legislation included provisions to route the
1,000-mile, 500-kV Gateway West line through the Morley Nelson Snake River Birds of Prey National
Conservation Area, and the BLM is expected to soon issue a right-of-way grant for the line sections that
cross that area.

to our low-cost hydroelectric power, diverse
generation portfolio and purposeful regulatory
strategy, our business continues to earn a fair return
on investments while keeping customer rates low.
Our last general rate case was fi led in 2011 — in 2018,
we will continue assessing the need to fi le a general
rate case in the coming years.

ADITC Preservation
Idaho Power’s eff orts have been targeted on preserving Accumulated Deferred
Investment Tax Credits (ADITC) under a 2014 regulatory settlement. We will
continue to be diligent in managing costs and growing revenues with the goal
to preserve credits for future years. Th e company did not use any additional
ADITC amortization during 2017. Th is preserves the full $45 million of credits
for future years.
REDUCE
Valmy Rate Base Adjustment Stipulations
In May 2017, the IPUC approved a settlement stipulation allowing
accelerated depreciation and cost recovery for the coal-fi red North
Valmy power plant. Th e stipulation provides for an increase in Idaho
jurisdictional revenues of $13.3 million per year and accelerated
depreciationon unit 1 through 2019 and unit 2 through 2025.
In June 2017, the OPUC also approved a settlement stipulation
allowing for accelerated depreciation of units 1 and 2 through
Dec. 31, 2025, cost recovery of incremental Valmy plant investments
through May 31, 2017, and forecasted decommissioning costs.
Th e settlement stipulation provides for an increase in the Oregon
jurisdictional revenue requirement of $1.1 million, with yearly
adjustments to the level of decommissioning cost recovery,
if warranted, until decommissioning activities are concluded.
As required by the Idaho stipulation, Idaho Power is working
closely with the co-owner of the Valmy plant to end Idaho Power's
participation in the operation of unit 1 by the end of 2019 and
unit 2 by the end of 2025.

Energy Imbalance Market
In March 2016, Idaho Power signed an agreement to participate in the Western EIM beginning in April 2018,
contingent upon necessary regulatory approvals and other conditions. Th e Western EIM is intended to reduce
the power supply cost to serve customers through more effi cient dispatch of a larger and more diverse pool
of resources, to integrate intermittent power from renewable generation resources more eff ectively and to
enhance reliability.
Idaho Power is working on completing its fi nal readiness criteria. On Feb. 1, 2018, Idaho Power entered “parallel
operations,” where effi cient dispatch occurs, but the bids into the market are not fi nancially binding. Th is is the
fi nal stage for operational preparedness prior to expected full participation on April 4, 2018.
Regulatory Mechanisms
To address the volatility of power supply costs, Power Cost Adjustment (PCA) mechanisms in Idaho and
Oregon allow Idaho Power to recover from or refund to customers most of the fl uctuations in power
supply costs. In the Idaho jurisdiction, the PCA includes a cost- or benefi t-sharing ratio that allocates the
deviations in net power supply expenses between customers (95 percent) and Idaho Power (5 percent),
with the exception of PURPA power purchases and demand response program incentives, which are
allocated 100 percent to customers.
As approved, the 2017 PCA increase was $10.6 million, eff ective June 1, 2017. Th e main factors contributing
to the increase included higher costs associated with new solar and wind power purchase agreements
under PURPA, higher coal-fi red generation costs, and prior year actual power costs exceeding forecast
costs due to worse-than-expected water conditions in 2016.
Th e Fixed Cost Adjustment (FCA) mechanism is designed to remove Idaho Power’s fi nancial disincentive
to invest in energy effi ciency programs by separating (or decoupling) the recovery of fi xed costs from the
variable kilowatt-hour charge and linking it instead to a set amount per customer. In 2017, a $6.9 million
increase in annual revenue was approved for the FCA.

Customer Growth
Idaho Power continues to see growth within its service area—its
customer base grew by 2.0 percent in 2017 and employment grew by
approximately 3.7 percent. Our total general business customer base
has grown to more than 545,000. And on July 7, the company set an
all-time peak demand record of 3,422 MW. Customer growth in Idaho
Power's service area continues to positively impact revenues.
Economic Development
Idaho’s economy continues to thrive. According to a recent Bloomberg article, Idaho has the strongest
economy in the nation based on an index that measures employment, personal income, home prices,
mortgage delinquency, tax revenue and the stock market.
Economic development brings great opportunities for large commercial and industrial growth.
Idaho Power’s energy sales for this customer segment increased 3.9 percent in 2017, refl ecting growth
that is largely due to an increase of new and expanding customers, such as CS Beef Packers, Great
Western Malting and Woodgrain Millwork. In addition, Capitol Distributing began construction on a
200,000 square-foot distribution center in Caldwell that will serve 450 convenience stores, and McCain
Foods announced a $200 million expansion to its frozen potato processing facility in southern Idaho.
Future expansions include Jayco, St. Luke’s and the Federal Bureau of Investigation, to name a few.

Customer Experience
Improving the customer experience was a
focus for Idaho Power in 2017. We undertook a
series of strategic initiatives aimed at showing
customers that they matter to us, that they can
count on us to provide reliable service and that
we promptly address customer needs and fi nd
innovative solutions. We streamlined many
customer touchpoints to make it easier for people
to do business with us, and we continued to be
thoughtful, engaged members of the community.
Our eff ort paid off with a 39-point increase in
the annual J.D. Power Residential Customer
Satisfaction survey, from 704 in 2016 to 743 in
2017 — a new all-time high. We are continuing to
emphasize the customer experience going forward.
Looking Forward
2017 was fi lled with growth and success for
IDACORP. From setting new records in our
customer satisfaction rating and peak demand
to achieving a 10th consecutive year of earnings
growth, Idaho Power continued to thrive. Our
1,972 dedicated employees stood out as
environmental stewards and corporate citizens
while helping the company reach its business goals.
As we look to the future, we are planning for
Idaho Power to continue to grow and prosper as our
service area attracts new business and residential
customers. In addition to a continued focus on the
customer experience, our company’s goals in 2018
include growing to enhance fi nancial strength,
improving our core business, enhancing our brand
and focusing on safety and employee engagement.
Idaho Power remains dedicated to providing
reliable, responsible, fair-priced energy, today
and tomorrow. Our commitment to our core
values of integrity, safety and respect remains
strong. And our path forward is clear as we work
to continue to grow our business and shareholder
value. We appreciate your continued investment
in IDACORP, and we look forward to another
great year in 2018.

PART I
ITEM 1. BUSINESS
OVERVIEW
Background
IDACORP, Inc. (IDACORP) is a holding company incorporated in 1998 under the laws of the state of Idaho. Its principal
operating subsidiary is Idaho Power Company (Idaho Power). IDACORP is subject to the provisions of the Public Utility
Holding Company Act of 2005, which provides the Federal Energy Regulatory Commission (FERC) and state utility regulatory
commissions with access to books and records and imposes record retention and reporting requirements on IDACORP.
Idaho Power was incorporated under the laws of the state of Idaho in 1989 as the successor to a Maine corporation that was
organized in 1915 and began operations in 1916. Idaho Power is an electric utility engaged in the generation, transmission,
distribution, sale, and purchase of electric energy and capacity and is regulated by the state regulatory commissions of Idaho
and Oregon and by the FERC. Idaho Power is the parent of Idaho Energy Resources Co. (IERCo), a joint venturer in Bridger
Coal Company (BCC), which mines and supplies coal to the Jim Bridger generating plant owned in part by Idaho Power. Idaho
Power's utility operations constitute nearly all of IDACORP's current business operations and are IDACORP’s only reportable
business segment. Segment financial information is presented in Note 17 – "Segment Information" to the consolidated financial
statements included in this report. As of December 31, 2017, IDACORP had 1,972 full-time employees, 1,964 of whom were
employed by Idaho Power, and 11 part-time employees, 9 of whom were employed by Idaho Power.
IDACORP’s other notable subsidiaries include IDACORP Financial Services, Inc. (IFS), an investor in affordable housing and
other real estate investments, and Ida-West Energy Company (Ida-West), an operator of small hydroelectric generation projects
that satisfy the requirements of the Public Utility Regulatory Policies Act of 1978 (PURPA).
IDACORP’s and Idaho Power’s principal executive offices are located at 1221 W. Idaho Street, Boise, Idaho 83702, and the
telephone number is (208) 388-2200.

UTILITY OPERATIONS
Background
Idaho Power provided electric utility service to more than 545,000 general business customers in southern Idaho and eastern
Oregon as of December 31, 2017. Approximately 454,000 of these customers are residential. Idaho Power’s principal
commercial and industrial customers are involved in food processing, electronics and general manufacturing, agriculture, health
care, and winter recreation. Idaho Power holds franchises, typically in the form of right-of-way arrangements, in 72 cities in
Idaho and 7 cities in Oregon and holds certificates from the respective public utility regulatory authorities to serve all or a
portion of 25 counties in Idaho and 3 counties in Oregon. Idaho Power's service area is shaded in the illustration on the
following page and covers approximately 24,000 square miles with an estimated population of 1.2 million.
7
Idaho Power is under the jurisdiction (as to rates, service, accounting, and other general matters of utility operation) of the
Idaho Public Utilities Commission (IPUC), the Public Utility Commission of Oregon (OPUC), and the FERC. The IPUC and
OPUC determine the rates that Idaho Power is authorized to charge to its general business customers. Idaho Power is also under
the regulatory jurisdiction of the IPUC, the OPUC, and the Public Service Commission of Wyoming as to the issuance of debt
and equity securities. As a public utility under the Federal Power Act (FPA), Idaho Power has authority to charge market-based
rates for wholesale energy sales under its FERC tariff and to provide transmission services under its open access transmission
tariff (OATT). Additionally, the FERC has jurisdiction over Idaho Power's sales of transmission capacity and wholesale
electricity, hydroelectric project relicensing, and system reliability, among other items.
Regulatory Accounting
Idaho Power is subject to accounting principles generally accepted in the United States of America, with the impacts of rate
regulation reflected in its financial statements. These principles sometimes result in Idaho Power recording expenses and
revenues in a different period than when an unregulated enterprise would record such expenses and revenues. In these instances,
the amounts are deferred or accrued as regulatory assets or regulatory liabilities on the balance sheet and recorded on the
income statement when recovered or returned in rates or when otherwise directed to begin amortization by a regulator.
Additionally, regulators can impose regulatory liabilities upon a regulated company for amounts previously collected from
customers that are expected to be refunded. Idaho Power records regulatory assets or liabilities if it is probable that they will be
reflected in future prices, based on regulatory orders or other available evidence.
8
Business Strategy
IDACORP is committed to its focus on competitive total returns and generating long-term value for shareholders. IDACORP’s
business strategy emphasizes Idaho Power as IDACORP’s core business, as Idaho Power's regulated utility operations are the
primary driver of IDACORP's operating results. IDACORP's board of directors has reviewed and affirmed its and Idaho
Power's long-term strategy, which is focused on the following areas and related initiatives:

employees, and other stakeholders. Idaho Power is working to continue to provide safe, affordable, reliable service to its
customers from a diversified source of generation resources, with a continued commitment to strong, sustainable financial
results and strong credit ratings.
Rates and Revenues
Idaho Power generates revenue primarily through the sale of electricity to retail and wholesale customers and the provision of
transmission service. The prices that the IPUC, the OPUC, and the FERC authorize Idaho Power to charge for the electric
power and services Idaho Power sells are critical factors in determining IDACORP's and Idaho Power's results of operations
and financial condition. In addition to the discussion below, for more information on Idaho Power's regulatory framework and
rate regulation, see the “Regulatory Matters” section of Part II, Item 7 – “Management’s Discussion and Analysis of Financial
Condition and Results of Operations” (MD&A) and Note 3 – “Regulatory Matters” to the consolidated financial statements
included in this report.
Retail Rates: Idaho Power continually evaluates the need to request changes to its retail electricity price structure to cover its
operating costs and to earn a fair return on its investments. Idaho Power uses general rate cases, power cost adjustment
mechanisms in Idaho and Oregon, a fixed cost adjustment (FCA) mechanism in Idaho, balancing accounts and tariff riders, and
subject-specific filings to recover its costs of providing service and to earn a return on investment. Retail prices are generally
determined through formal ratemaking proceedings that are conducted under established procedures and schedules before the
issuance of a final order. Participants in these proceedings include Idaho Power, the staffs of the IPUC or OPUC, and other
interested parties. The IPUC and OPUC are charged with ensuring that the prices and terms of service are fair, non-
discriminatory, and provide Idaho Power an opportunity to recover its prudently incurred or allowable costs and expenditures
and earn a reasonable return on investment. The ability to request rate changes does not, however, ensure that Idaho Power will
recover all of its costs or earn a specified rate of return, or that its costs will be recovered in advance of or at the same time as
the costs are incurred.
In addition to general rate case filings, ratemaking proceedings can involve charges or credits related to specific costs,
programs, or activities, as well as the recovery or refund of amounts recorded under specific authorization from the IPUC or
9
OPUC but deferred for recovery or refund. Deferred amounts are generally collected from or refunded to retail customers
through the use of base rates or supplemental tariffs. Outside of base rates, three of the most significant mechanisms for
recovery of costs are the power cost adjustment mechanisms, FCA mechanism, and energy efficiency rider. The Idaho and
Oregon power cost adjustment mechanisms are intended to address the volatility of power supply costs and provide for annual
adjustments to the rates charged to retail customers by allowing partial recovery or refund of the difference between net power
supply costs included in base rates and actual net power supply costs incurred by Idaho Power. The FCA mechanism is
designed to remove Idaho Power’s financial disincentive to invest in energy efficiency programs by separating (or decoupling)
the recovery of fixed costs from the variable kilowatt-hour charge for certain Idaho customer classes and linking it instead to a
set amount per customer. Separately, Idaho Power collects most of its energy efficiency program costs through an energy
efficiency rider on customer bills.
Wholesale Markets: Idaho Power’s OATT transmission rate is revised each year based primarily on financial and operational
data Idaho Power files annually with the FERC in its Form 1. The Energy Policy Act of 2005 granted the FERC increased
statutory authority to implement mandatory transmission and network reliability standards, as well as enhanced oversight of
power and transmission markets, including protection against market manipulation. These mandatory transmission and
reliability standards were developed by the North American Electric Reliability Corporation (NERC) and the Western
Electricity Coordinating Council (WECC), which have responsibility for compliance and enforcement of transmission and
reliability standards.
Idaho Power participates in the wholesale energy markets by purchasing power to help meet load demands and selling power
that is in excess of load demands. Idaho Power's market activities are guided by a risk management policy and frequently
updated operating plans. These operating plans are impacted by factors such as customer demand for power, market prices,
generating costs, transmission constraints, and availability of generating resources. Some of Idaho Power's 17 hydroelectric
generation facilities are operated to optimize the water that is available by choosing when to run hydroelectric generation units
and when to store water in reservoirs. Idaho Power at times operates these and its other generation facilities to take advantage
of market opportunities. These decisions affect the timing and volumes of market purchases and market sales. Even in below-
normal water years, there are opportunities to vary water usage to capture wholesale marketplace economic benefits, maximize
generation unit efficiency and meet peak loads. Compliance factors such as allowable river stage elevation changes and flood
control requirements also influence these generation dispatch decisions. Idaho Power's off-system sales revenues depend largely
on the availability of generation resources above the amount necessary to serve customer loads as well as market power prices
at the time when those resources are available. A reduction in either factor leads to lower off-system sales revenue.
Energy Sales: Weather, seasonal customer demand, and economic conditions all impact the amount of electricity that Idaho
Power sells as well as the costs it incurs to provide that electricity. Idaho Power's utility revenues are not earned, and associated
expenses are not incurred, evenly during the year. Idaho Power’s retail energy sales typically peak during the summer irrigation
and cooling season, with a lower peak in the winter. Extreme temperatures increase sales to customers who use electricity for
cooling and heating, and moderate temperatures decrease sales. Increased precipitation levels during the agricultural growing
season reduce electricity sales to customers who use electricity to operate irrigation pumps. The table that follows presents
Idaho Power’s revenues and sales volumes for the last three years, classified by customer type. Approximately 95 percent of
Idaho Power’s general business revenue originates from customers located in Idaho, with the remainder originating from
customers located in Oregon. Idaho Power’s operations, including information on energy sales, are discussed further in Part II,
Item 7 - MD&A - "Results of Operations - Utility Operations.”

Competition: Idaho Power's electric utility business has historically been recognized as a natural monopoly. Idaho Power's rates
for retail electric services are generally determined on a “cost of service” basis. Rates are designed to provide, after recovery of
allowable operating expenses including depreciation on capital investments, an opportunity for Idaho Power to earn a
reasonable return on investment as authorized by regulators. However, alternative methods of generation, including customer-
owned solar and other forms of distributed generation, compete with Idaho Power for sales to existing customers. Also,
development of new technologies and services to help energy consumers manage energy in new ways could continue to alter
demand for Idaho Power's electric energy. Idaho Power also competes with fuel distribution companies, including natural gas
providers, in serving the energy needs of customers for space heating, water heating, and appliances.
Idaho Power also participates in the wholesale energy markets and in the electric transmission markets. Generally, these
wholesale markets are regulated by the FERC, which requires electric utilities to transmit power to or for wholesale purchasers
and sellers and make available, on a non-discriminatory basis, transmission capacity for the purpose of providing these services.
In return for agreeing to provide service to all customers within a defined service area, electric utilities are typically provided
with an exclusive right to provide service in that service area. However, certain prescribed areas within Idaho Power's service
area, such as municipalities or Native American Tribal reservations, may elect not to take service from Idaho Power and instead
operate as a municipal electric utility or otherwise as a separate entity. In such cases, the entity would be required to purchase or
otherwise obtain rights (such as by contract) to Idaho Power's distribution infrastructure within the municipal or other
designated area. Idaho Power would have no responsibility for providing electric service to the municipal or separate entity,
absent Idaho Power's voluntary execution of an agreement to provide that service. Separately, the Shoshone-Bannock Tribes,
located in southeastern Idaho, have considered the adoption of a utility code applicable to electric utilities operating within the
Shoshone-Bannock Tribal Reservation (Reservation). The tribal utility code, if adopted, could ultimately lead to Idaho Power's
cessation of its historical provision of service to the Reservation and could result in either no or a limited electric service
relationship with the Reservation, or could result solely in Idaho Power's sale of power to the Reservation pursuant to a power
purchase agreement. Idaho Power estimates that the average load for the Reservation over the prior five years is approximately
14 Megawatts (MW).
Power Supply
Overview: Idaho Power primarily relies on company-owned hydroelectric, coal-fired, and gas-fired generation facilities and
long-term power purchase agreements to supply the energy needed to serve customers. Market purchases and sales are used to
11
supplement Idaho Power's generation and balance supply and demand throughout the year. Idaho Power’s generating plants and
their capacities are listed in Part I, Item 2 - “Properties.”
Weather, load demand, supply constraints, economic conditions, and availability of generation resources impact power supply
costs. Idaho Power’s annual hydroelectric generation varies depending on water conditions in the Snake River Basin. Drought
conditions and increased peak load demand cause a greater reliance on potentially more expensive energy sources to meet load
requirements. Conversely, favorable hydroelectric generation conditions increase production at Idaho Power’s hydroelectric
generating facilities and reduce the need for thermal generation and wholesale market purchased power. Economic conditions
and governmental regulations can affect the market price of natural gas and coal, which may impact fuel expense and market
prices for purchased power. Idaho Power's power cost adjustment mechanisms mitigate in large part the potentially adverse
financial statement impacts of volatile fuel and power costs.
Idaho Power’s system is dual peaking, with the larger peak demand occurring in the summer. The all-time system peak demand
was 3,422 MW, set on July 7, 2017. On January 6, 2017, Idaho Power tied its highest all-time winter peak demand of 2,527
MW, which was originally set on December 10, 2009. During these and other similarly heavy load periods, Idaho Power’s
system is fully committed to serve load and meet required operating reserves. The table that follows shows Idaho Power’s total
power supply for the last three years.

Hydroelectric Generation: Idaho Power operates 17 hydroelectric projects located on the Snake River and its tributaries.
Together, these hydroelectric facilities provide a total nameplate capacity of 1,706 MW and annual generation of approximately
8.5 million MWh under median water conditions. The amount of water available for hydroelectric power generation depends on
several factors—the amount of snowpack in the mountains upstream of Idaho Power’s hydroelectric facilities, upstream
reservoir storage, springtime precipitation and temperatures, main river and tributary base flows, the condition of the Eastern
Snake Plain Aquifer and its spring flow impact, summer time irrigation withdrawals and returns, and upstream reservoir
regulation. Idaho Power actively participates in collaborative work groups focused on water management issues in the Snake
River Basin, with the goal of preserving the long-term availability of water for use at Idaho Power’s hydroelectric projects on
the Snake River.
In 2017, above normal winter and spring precipitation resulted in 8.9 million MWh of hydroelectric generation, a significant
increase from the past two years. In 2016, low upstream reservoir carryover (primarily in the upper Snake River basin) resulted
in reduced downstream flow releases. Additionally, although snowpack accumulation was near-normal on April 1, 2016, the
snowpack melted earlier than usual. The combined effect was lower than median hydro production of 6.4 million MWh in
2016. In 2015, below-normal snow accumulation resulted in a lower than median hydro production of 5.9 million MWh.
During low water years, when stream flows into Idaho Power’s hydroelectric projects are reduced, Idaho Power’s hydroelectric
generation is reduced, resulting in a greater reliance on other generation resources and power purchases. For 2018, Idaho Power
estimates annual generation from its hydroelectric facilities to be between 7.5 million MWh and 9.5 million MWh.
Idaho Power obtains licenses for its hydroelectric projects from the FERC, similar to other utilities that operate nonfederal
hydroelectric projects on qualified waterways. The licensing process includes an extensive public review process and involves
numerous natural resource and environmental agencies. The licenses last from 30 to 50 years depending on the size,
complexity, and cost of the project. Idaho Power is actively pursuing the relicensing of the Hells Canyon Complex, its largest
hydroelectric generation source. Idaho Power also has three Oregon licenses under the Oregon Hydroelectric Act, which applies
12
to Idaho Power’s Brownlee, Oxbow, and Hells Canyon facilities. For further information on relicensing activities, see Part II,
Item 7 – MD&A – "Regulatory Matters – Relicensing of Hydroelectric Projects.”
Idaho Power is subject to the provisions of the FPA as a “public utility” and as a “licensee” by virtue of its hydroelectric
operations. As a licensee under Part I of the FPA, Idaho Power and its licensed hydroelectric projects are subject to conditions
described in the FPA and related FERC regulations. These conditions and regulations include, among other items, provisions
relating to condemnation of a project upon payment of just compensation, amortization of project investment from excess
project earnings, and possible takeover of a project after expiration of its license upon payment of net investment and severance
damages.
Coal-Fired Generation: Idaho Power co-owns the following coal-fired power plants:
•
Jim Bridger, located in Wyoming, in which Idaho Power has a one-third interest;
• North Valmy, located in Nevada, in which Idaho Power has a 50 percent interest; and
• Boardman, located in Oregon, in which Idaho Power has a 10 percent interest.
BCC supplies coal to the Jim Bridger power plant. IERCo, a wholly-owned subsidiary of Idaho Power, owns a one-third
interest in BCC and PacifiCorp owns a two-third interest in BCC and is the operator of the Bridger Coal Mine. The mine
operates under a long-term sales agreement that provides for delivery of coal through 2024 from surface and underground
sources. Idaho Power believes that BCC has sufficient reserves to provide coal deliveries for at least the term of the sales
agreement. Idaho Power also has a coal supply contract providing for annual deliveries of coal through 2021 from the Black
Butte mine located near the Jim Bridger plant. This contract supplements the BCC deliveries and provides another coal supply
to fuel the Jim Bridger plant. The Jim Bridger plant’s rail load-in facility and unit coal train, while limited, provides the
opportunity to access other fuel supplies for tonnage requirements above established contract minimums.
NV Energy is the operator of the North Valmy power plant (Valmy Plant). Idaho Power's existing coal inventory at the Valmy
Plant is expected to meet Idaho Power's projected coal requirements at the plant through at least 2018. Idaho Power expects to
be able to obtain future coal requirements through coal supply contracts. In 2017, Idaho Power established a process approved
by the IPUC and OPUC for recovery of costs related to Idaho Power’s plan to end its participation in coal-fired operations at
the Valmy Plant units 1 and 2 in 2019 and 2025, respectively. In both 2017 and 2016, the Valmy Plant provided 2 percent of
Idaho Power's total generation. For additional information on the related settlement stipulations, see Part II, Item 7 – MD&A -
"Regulatory Matters - Valmy Base Rate Adjustment Settlement Stipulations and Depreciation Rate Settlement Stipulations."
Portland General Electric Company is the operator of the Boardman power plant. Idaho Power believes that it has sufficient
inventory and coal contracts to supply the Boardman plant with fuel through 2018. The Boardman plant receives coal through
annual contracts with suppliers from the Powder River Basin in northeast Wyoming. Idaho Power expects to meet future coal
needs through similar contracts. In December 2010, the Oregon Environmental Quality Commission approved a plan to cease
coal-fired operations at the Boardman power plant no later than December 31, 2020.
Natural Gas-fired Generation: Idaho Power owns and operates the Langley Gulch natural gas-fired combined cycle power
plant and the Danskin and Bennett Mountain natural gas-fired simple cycle combustion turbine power plants. All three plants
are located in Idaho.
Idaho Power operates the Langley Gulch plant as a baseload unit and the Danskin and Bennett Mountain plants to meet peak
supply needs. The plants are also used to take advantage of wholesale market opportunities. Natural gas for all facilities is
purchased based on system requirements and dispatch efficiency. The natural gas is transported through the Williams-Northwest
Pipeline under Idaho Power's 55,584 million British thermal units (MMBtu) per day long-term gas transportation service
agreements. These transportation agreements vary in contract length but generally contain the right for Idaho Power to extend
the term. In addition to the long-term gas transportation service agreements, Idaho Power has entered into a long-term storage
service agreement with Northwest Pipeline for 131,453 MMBtu of total storage capacity at the Jackson Prairie Storage Project.
This firm storage contract expires in 2043. Idaho Power purchases and stores natural gas with the intent of fulfilling needs as
identified for seasonal peaks or to meet system requirements.
As of December 31, 2017, approximately 6.5 million MMBtu of natural gas was financially hedged for physical delivery for the
operational dispatch of the Langley Gulch plant through June 2019. Idaho Power plans to manage the procurement of additional
natural gas for the peaking units on the daily spot market or from storage inventory as necessary to meet system requirements
and fueling strategies.
13
Purchased Power: As described below, Idaho Power purchases power in the wholesale market as well as power pursuant to
long-term power purchase contracts and exchange agreements.
Wholesale Market Transactions: To supplement its self-generated power and long-term purchase arrangements, Idaho Power
purchases power in the wholesale market based on economics, operating reserve margins, risk management policy
requirements, and unit availability. Depending on availability of excess power or generation capacity, pricing, and opportunities
in the markets, Idaho Power also sells power in the wholesale markets. During 2017 and 2016, Idaho Power purchased 0.9
million MWh and 1.4 million MWh of power through wholesale market purchases at an average cost of $26.32 per MWh and
$24.80 per MWh, respectively. During 2017 and 2016, Idaho Power sold 2.1 million MWh and 1.2 million MWh of power in
wholesale market sales, with an average price of $15.63 per MWh and $21.25 per MWh, respectively.
Long-term Power Purchase and Exchange Arrangements: In addition to its wholesale market purchases, Idaho Power has the
following notable firm long-term power purchase contracts and energy exchange agreements:
• Telocaset Wind Power Partners, LLC - for 101 MW (nameplate generation) from its Elkhorn Valley wind project
located in eastern Oregon. The contract term is through 2027.
• USG Oregon LLC - for 22 MW (estimated average annual output) from the Neal Hot Springs #1 geothermal power
plant located near Vale, Oregon. The contract term ends in 2037.
• Clatskanie People's Utility - for the exchange of up to 18 MW of energy from the Arrowrock hydroelectric project in
southern Idaho in exchange for energy from Idaho Power's system or power purchased at the Mid-Columbia trading
hub. The contract term continues through 2020. Idaho Power has the right to renew the agreement for an additional
five-year term.
• Raft River Energy I, LLC - for up to 13 MW (nameplate generation) from its Raft River Geothermal Power Plant Unit
#1 located in southern Idaho. The contract term ends in 2033.
PURPA Power Purchase Contracts: Idaho Power purchases power from PURPA projects as mandated by federal law. As of
December 31, 2017, Idaho Power had contracts with on-line PURPA-related projects with a total of 1,114 MW of nameplate
generation capacity, with an additional 5 MW nameplate capacity of projects projected to be on-line in 2018 and an additional
24 MW expected to be added in 2019. The power purchase contracts for these projects have original contract terms ranging
from one to 35 years. The expense and volume of PURPA project power purchases during the last three years is included in the
following table:

Pursuant to the requirements of PURPA, the IPUC and OPUC have each issued orders and rules regulating Idaho Power’s
purchase of power from "qualifying facilities" that meet the requirements of PURPA. A key component of the PURPA contracts
is the energy price contained within the agreements. PURPA regulations specify that a utility must pay energy prices based on
the utility’s avoided costs. The IPUC and OPUC have established specific rules and regulations to calculate the avoided cost
that Idaho Power is required to include in PURPA contracts. For PURPA power purchase agreements:
•
•
Idaho Power is required to purchase all of the output from the facilities located inside its service area, subject to some
exceptions such as adverse impacts on system reliability.
Idaho Power is required to purchase the output of projects located outside its service area if it has the ability to receive
power at the facility’s requested point of delivery on Idaho Power's system.
• The IPUC jurisdictional portion of the costs associated with PURPA contracts is fully recovered through base rates and
the Idaho PCA mechanism, and the OPUC jurisdictional portion is recovered through base rates and an Oregon power
cost recovery mechanism. Thus, the primary impact of high power purchase costs under PURPA contracts is on
customer rates.
• OPUC jurisdictional regulations have generally provided for PURPA standard contract terms of up to 20 years.
• The IPUC requires Idaho Power to pay "published avoided cost" rates for all wind and solar projects that are smaller
than 100 kilowatts (kW) and all other types of projects that are smaller than 10 average MWs. For PURPA qualifying
facilities that exceed these size limitations, Idaho Power is required to negotiate an applicable price (premised on
avoided costs) based upon IPUC regulations.
14
• The IPUC issued an order in August 2015 that revised the standard PURPA power purchase contract term for new
contracts to a 2-year term from the previously required 20-year term for projects that exceed the size limitations for
published avoided costs.
• The OPUC requires that Idaho Power pay the published avoided costs for solar PURPA qualifying facilities with a
nameplate rating of 3 MW or less and all other types of projects with a nameplate rating of 10 MW or less. Idaho
Power is required to negotiate an applicable price (premised on avoided costs) for all other qualifying facilities based
upon OPUC regulations.
Anticipated Participation in Western Energy Imbalance Market: Utilities in the western United States outside the California
Independent System Operator (California ISO) have traditionally relied upon a combination of automated and manual dispatch
within the hour to balance generation and load to maintain reliable supply. These utilities have limited capability to transact
within the hour outside their balancing area. In contrast, energy imbalance markets use automated intra-hour economic dispatch
of generation from committed resources to serve loads. The California ISO and PacifiCorp implemented an energy imbalance
market in 2014 (Western EIM) under which the parties enabled their systems to interact for dispatch purposes. The Western
EIM is intended to reduce the power supply costs to serve customers through more efficient dispatch of a larger and more
diverse pool of resources, to integrate intermittent power from renewable generation sources more effectively, and to enhance
reliability. Participation in the Western EIM is voluntary and available to all balancing authorities in the western United
States. Following an evaluation of the potential power supply cost savings and other advantages, system upgrade requirements,
and estimated capital and ongoing operating costs, Idaho Power executed an agreement under which it intends to, subject to
regulatory approval and other conditions, participate in the Western EIM. Idaho Power anticipates that it will commence
participation in the Western EIM in April 2018. For information on regulatory proceedings related to costs associated with
joining the Western EIM, see Part II, Item 7 – MD&A - "Regulatory Matters - Recovery of Costs for Anticipated Participation
in Western Energy Imbalance Market."
Transmission Services
Electric transmission systems deliver energy from electric generation facilities to distribution systems for final delivery to
customers. Transmission systems are designed to move electricity over long distances because generation facilities can be
located hundreds of miles away from customers. Idaho Power’s generating facilities are interconnected through its integrated
transmission system and are operated on a coordinated basis to achieve maximum capability and reliability. Idaho Power’s
transmission system is directly interconnected with the transmission systems of the Bonneville Power Administration, Avista
Corporation, PacifiCorp, NorthWestern Energy, and NV Energy. These interconnections, coupled with transmission line
capacity made available under agreements with some of those entities, permit the interchange, purchase, and sale of power
among entities in the Western Interconnection, the transmission grid covering much of western North America. Idaho Power
provides wholesale transmission service for eligible transmission customers on a non-discriminatory basis. Idaho Power is a
member of the WECC, the Northwest PowerPool, the Northern Tier Transmission Group, and the North American Energy
Standards Board. These groups have been formed to more efficiently coordinate transmission reliability and planning
throughout the Western Interconnection.
Transmission to serve Idaho Power's retail customers is subject to the jurisdiction of the IPUC and OPUC for retail rate making
purposes. Idaho Power provides cost-based wholesale and retail access transmission services under the terms of a FERC
approved OATT. Services under the OATT are offered on a nondiscriminatory basis such that all potential customers, including
Idaho Power, have an equal opportunity to access the transmission system. As required by FERC standards of conduct, Idaho
Power's transmission function is operated independently from Idaho Power's energy marketing function.
Idaho Power is jointly working on the permitting of two significant transmission projects. The Boardman-to-Hemingway line is
a proposed 300-mile, 500-kV transmission project between a station near Boardman, Oregon and the Hemingway station near
Boise, Idaho. The Gateway West line is a proposed 1,000-mile, 500-kV transmission project between a station located near
Douglas, Wyoming and the Hemingway station. Both projects are intended to meet future anticipated resource needs and are
discussed in Part II, Item 7 – MD&A - "Liquidity and Capital Resources - Capital Requirements" in this report.
Resource Planning
Integrated Resource Planning: The IPUC and OPUC require that Idaho Power prepare biennially an Integrated Resource Plan
(IRP). Idaho Power filed its most recent IRP in June 2017 (2017 IRP). The IRP seeks to forecast Idaho Power's loads and
resources for a 20-year period, analyzes potential supply-side and demand-side resource options, and identifies potential near-
term and long-term actions. The four primary goals of the IRP are to:
15
•
•
•
•
identify sufficient resources to reliably serve the growing demand for energy within Idaho Power's service area
throughout the 20-year planning period;
ensure the selected resource portfolio balances cost, risk, and environmental concerns;
give equal and balanced treatment to both supply-side resources and demand-side measures; and
involve the public in the planning process in a meaningful way.
During the time between IRP filings, the public and regulatory oversight of the activities identified in the IRP allows for
discussion and adjustment of the IRP as warranted. Idaho Power makes periodic adjustments and corrections to the resource
plan to reflect economic conditions, anticipated resource development, changes in technology, and regulatory requirements.
The load forecast assumptions Idaho Power used in the 2017 IRP are included in the table below, together with the average
annual growth rate assumptions used in the prior two IRPs. The rate of load growth can impact the timing and extent of
development of resources, such as new generation plants or transmission infrastructure, to serve those loads.

2013 IRP
Idaho Power's 2017 IRP identifies its preferred resource portfolio and action plan. The IRP includes the completion of the
Boardman-to-Hemingway 500-kV transmission line by 2026, the end of Idaho Power's participation in coal-fired operations at
the North Valmy power plant units 1 and 2 in 2019 and 2025, respectively, and the early retirement of Jim Bridger units 1 and 2
in 2032 and 2028, respectively, with no other new resource needs prior to 2026. However, as noted in the 2017 IRP, there is
considerable uncertainty surrounding the resource sufficiency estimates and project completion dates, including uncertainty
around the timing and extent of third party development of renewable resources, the actual completion date of the Boardman-
to-Hemingway transmission project, and the economics and logistics of plant retirements. These and other uncertainties could
result in changes to the desirability of the preferred portfolio and adjustments to the timing and nature of anticipated and actual
actions.
Energy Efficiency and Demand Response Programs: Idaho Power’s energy efficiency and demand response portfolio is
comprised of 24 programs. These energy efficiency programs target energy savings across the entire year, while the demand
response programs target system demand reduction in the summer at times of peak loads. The programs are offered to all
customer segments and emphasize the wise use of energy, especially during periods of high demand. This energy and demand
reduction can minimize or delay the need for new generation or transmission infrastructure. Idaho Power’s programs include:
•
•
•
•
financial incentives for irrigation customers for either improving the energy efficiency of an irrigation system or
installing new energy efficient systems;
energy efficiency for new and existing homes including electric heating, ventilation and cooling equipment, as well as
energy efficient building techniques, air duct sealing, and energy efficient lighting;
incentives to industrial and commercial customers for acquiring energy efficient equipment, and using energy
efficiency techniques for operational and management processes;
demand response programs to reduce peak summer demand through the voluntary cycling of central air conditioners
for residential customers, interruption of irrigation pumps, and reduction of commercial and industrial demand through
actions taken by business owners and operators; and
• membership in the Northwest Energy Efficiency Alliance, which supports market transformation efforts across the
region.
In 2017, Idaho Power’s energy efficiency programs reduced energy usage by approximately 170,000 MWh. For 2017, Idaho
Power had a demand response available capacity of approximately 394 MW. In 2017 and 2016, Idaho Power expended
approximately $48 million and $43 million, respectively, on both energy efficiency and demand response programs. Funding
for these programs is provided through a combination of the Idaho and Oregon energy efficiency tariff riders, base rates, and
the power cost adjustment mechanisms. Energy efficiency program expenditures funded through the riders are reported as an
operating expense with an equal amount of revenues recorded in other revenues, resulting in no net impact on earnings.
16
Environmental Regulation and Costs
Idaho Power's activities are subject to a broad range of federal, state, regional, and local laws and regulations designed to
protect, restore, and enhance the quality of the environment. Environmental regulation impacts Idaho Power’s operations due to
the cost of installation and operation of equipment and facilities required for compliance with environmental regulations, the
modification of system operations to accommodate environmental regulations, and the cost of acquiring and complying with
permits and licenses. In addition to generally applicable regulations, Idaho Power's three coal-fired power plants, three natural
gas combustion turbine power plants, and 17 hydroelectric generating plants are subject to a broad range of environmental
requirements, including those related to air and water quality, waste materials, and endangered species. For a more detailed
discussion of these and other environmental issues, refer to Item 7 - MD&A - "Environmental Matters" in this report.
Environmental Expenditures: Idaho Power’s environmental compliance expenditures will remain significant for the
foreseeable future, particularly given the volume of existing and proposed regulations at the federal level. Idaho Power
estimates its environmental expenditures, based upon present environmental laws and regulations, will be as follows for the
periods indicated, excluding allowance for funds used during construction (AFUDC) (in millions of dollars):
Capital expenditures:
License compliance and relicensing efforts at hydroelectric facilities
Investments in equipment and facilities at thermal plants
Total capital expenditures
Operating expenses:
Operating costs for environmental facilities - hydroelectric
Operating costs for environmental facilities - thermal

Idaho Power anticipates that finalization, implementation, or modification of a number of federal and state rulemakings and
other proceedings addressing, among other things, greenhouse gases and endangered species, could result in substantial changes
in operating and compliance costs, but Idaho Power is unable to estimate those changes in costs given the uncertainty
associated with existing and potential future regulations. Idaho Power expects that it would seek to recover increases in costs
through the ratemaking process. Beyond increasing costs generally, these environmental laws and regulations could affect
IDACORP's and Idaho Power's results of operations and financial condition if the costs associated with these environmental
requirements and potential early plant retirements cannot be fully recovered in rates on a timely basis.
Idaho Power monitors environmental requirements and assesses whether environmental control measures are or remain
economically appropriate. Continued review of the economic appropriateness of further investments in coal-fired plants was
included in a February 2014 order of the IPUC, in which the IPUC requested that Idaho Power continue monitoring
environmental requirements at a national level and account for their impact in resource planning and promptly apprise the IPUC
of developments that could impact the company's continued reliance on the Valmy Plant as a coal-fired resource.
In 2017, the IPUC and OPUC approved a settlement stipulation allowing accelerated depreciation and cost recovery for the
Valmy Plant in connection with Idaho Power's plan to end its participation in the operation of unit 1 at the Valmy Plant by the
end of 2019 and unit 2 by 2025. The plan to end Idaho Power's participation in operations of units 1 and 2 at the Valmy Plant
was based primarily on the economics of operating the plant. The settlement stipulations are described in Part II, Item 7 -
MD&A - "Regulatory Matters” in this report. Additionally, in light of the uncertainty resulting from pending environmental
regulation and the substantial estimated cost of selective catalytic reduction equipment (SCR) installation, Idaho Power is
assessing whether to move forward with the installation of SCR on units 1 and 2 at the Jim Bridger power plant.
Voluntary CO2 Intensity Reduction Goal: Idaho Power is engaged in voluntary greenhouse gas emissions (GHG) intensity
reduction efforts. In September 2009, IDACORP's and Idaho Power's boards of directors approved guidelines that established a
goal to reduce Idaho Power's resource portfolio's average carbon dioxide (CO2) emissions intensity for the 2010 through 2013
time period to a level of 10 to 15 percent below Idaho Power's 2005 CO2 emissions intensity of 1,194 lbs CO2/MWh. The
combination of effective utilization of hydroelectric projects, above average stream flows in some years, reduced usage of coal-
fired facilities, the purchase of renewable energy, and the addition of the Langley Gulch natural gas-fired power plant
positioned Idaho Power to extend its CO2 emissions intensity reduction goal period for an additional two years, targeting an
average reduction of 10 to 15 percent below its 2005 levels for the entire 2010 through 2015 time period. Idaho Power achieved
17
its initial reduction goal, as well as its extended goal, through 2015. Idaho Power's average CO2 emissions intensity from
company-owned resources for the 2010 through 2015 period was 21 percent below the 2005 CO2 emissions intensity level.
In 2015, Idaho Power further extended and expanded the goal, seeking to reduce the company-owned resource portfolio
average CO2 emissions intensity to 15-20 percent below 2005 levels for the 2010-2017 period. As of the date of this report,
Idaho Power achieved the reduction goal set in 2015, with carbon emissions intensity at 25 percent below the 2005 level, and
further extended the current CO2 emissions intensity reduction goal through 2020.
Idaho Power's estimated historic CO2 emissions intensity from its generation facilities was as follows:

IFS invests in affordable housing developments, which provide a return principally by reducing federal and state income taxes
through tax credits and accelerated tax depreciation benefits. IFS has focused on a diversified approach to its investment
strategy in order to limit both geographic and operational risk with most of IFS’s investments having been made through
syndicated funds. IFS is no longer actively pursuing further investment opportunities, but will continue to maintain and manage
its current portfolio of investments. At December 31, 2017, the unamortized amount of IFS’s portfolio was approximately $6
million ($165 million in gross tax credit investments, net of $159 million of accumulated amortization). IFS generated tax
credits of $2.6 million in both 2017 and 2016 and $3.3 million in 2015. In 2017 and 2016, IFS received distributions related to
fully-amortized affordable housing investments that reduced IDACORP's income tax expense by $1.1 million and $1.7 million,
respectively.

ITEM 1A. RISK FACTORS
IDACORP and Idaho Power operate in a highly regulated industry and business environment that involves significant risks,
many of which are beyond the companies' control. The circumstances and factors set forth below may have a material impact
on the business, financial condition, or results of operations of IDACORP and Idaho Power and could cause actual results or
outcomes to differ materially from those discussed in any forward-looking statements. These risk factors, as well as other
information in this report, including without limitation, in Part II - Item 7 - "Management's Discussion and Analysis of
Financial Condition and Results of Operations - Matters Impacting Future Results" in this report, and information in other
reports the companies file with the SEC, should be considered carefully when making any investment decisions relating to
IDACORP or Idaho Power.
State or federal regulators may not approve customer rates that provide timely or sufficient recovery of Idaho Power's costs
or allow Idaho Power to earn a reasonable rate of return, which could cause IDACORP's and Idaho Power's financial
condition and results of operations to be adversely affected.
The prices that the IPUC and OPUC authorize Idaho Power to charge customers for its retail services, and the tariff rate that the
FERC permits Idaho Power to charge for its transmission services, are generally the most significant factors influencing
19
IDACORP’s and Idaho Power’s business, results of operations, liquidity, and financial condition. Idaho Power's ability to
recover its costs and earn a reasonable rate of return can be affected by many regulatory factors, including the timing difference
between when costs are incurred and when those costs are recovered in customers’ rates (often called "regulatory lag" in the
utility industry), and differences between the costs embedded in rates and the amount of actual costs incurred. Idaho Power is
often required to incur costs before the IPUC, OPUC, or FERC approves the recovery of those costs, such as construction costs
for new facilities or power lines, the costs of compliance with legislative and regulatory requirements and the costs of damage
from natural disasters. The IPUC, OPUC, and FERC may not allow Idaho Power to recover some or all of those costs on the
basis that Idaho Power did not reasonably or prudently incur those costs or for other reasons. While rate regulation is premised
on the assumption that rates established are fair, just, and reasonable, regulators have considerable discretion in applying this
standard. Decisions are subject to judicial appeal, which could lead to further uncertainty in regulatory proceedings. In response
to economic, political, legislative, public policy, and regulatory pressures, Idaho Power may be subject to rate increase
moratoriums, rate reductions or refunds, limits on rate increases, and lower allowed rates of return on investments. The
ratemaking process typically involves multiple intervening parties, including governmental bodies, consumer advocacy groups,
and customers, generally with the common objective of limiting rate increases or even reducing rates. The IPUC and OPUC
may adopt different methods of calculating the allocation of the total utility costs in their respective jurisdictions, resulting in
certain costs excluded in both states. In a number of proceedings in recent years, Idaho Power has been denied recovery, or
required to defer recovery pending the next general rate case, including denials or deferrals related to capital expenditures for
long-term projects expenses. Adverse outcomes in regulatory proceedings or significant regulatory lag may cause Idaho Power
to record an impairment of its assets or otherwise adversely affect cash flows and earnings and result in lower credit ratings,
reduced access to capital and higher financing costs, and reductions or delays in planned capital expenditures.
For additional information relating to Idaho Power's state and federal regulatory framework and regulatory matters, see Part I -
Item 1 - "Business - Utility Operations," Note 3 - "Regulatory Matters" to the consolidated financial statements included in this
report, and Part II - Item 7 - "Management's Discussion and Analysis of Financial Condition and Results of Operations -
Regulatory Matters" in this report.
Idaho Power's cost recovery mechanisms may not function as intended and are subject to change, which may adversely
affect IDACORP's and Idaho Power's financial condition and results of operations. Idaho Power has power cost adjustment
mechanisms in its Idaho and Oregon jurisdictions and a fixed cost adjustment mechanism in Idaho. The power cost adjustment
mechanisms track Idaho Power’s actual net power supply costs (primarily fuel and purchased power less off-system sales) and
compare these amounts to net power supply costs being recovered in retail rates. A majority of the difference between these two
amounts is deferred for future recovery from, or refund to, customers through rates. Volatility in power supply costs continues
to be significant, in large part due to fluctuations in hydroelectric generation conditions and high costs for the purchase of
renewable energy under mandatory long-term contracts. While the power cost adjustment mechanisms function to mitigate the
potentially adverse impact on net income of power supply cost volatility, the mechanisms do not eliminate the cash flow impact
of that volatility. When power costs rise above the level recovered in current retail rates, Idaho Power incurs the costs but
recovery of those costs is deferred to a subsequent collection period, which can adversely affect Idaho Power’s operating cash
flow and liquidity until those costs are recovered from customers. The fixed cost adjustment mechanism is a decoupling
mechanism designed to remove Idaho Power's disincentive to invest in energy efficiency activities by allowing Idaho Power to
charge residential and small commercial customers when it recovers less than the base level of fixed costs per customer that the
IPUC authorized for recovery in the most recent general rate case. The power cost and fixed cost adjustment mechanisms are
generally subject to change at the discretion of applicable state regulators, who could decide to modify or eliminate either
mechanism in a manner that adversely impacts IDACORP's and Idaho Power's financial condition, cash flows, and results of
operations.
IDACORP's and Idaho Power's business, financial condition, and results of operations may be negatively affected by
changes in customer growth or customer usage. Growth in the number of customers and customers' use of electricity are
affected by a number of factors, such as population growth or decline in Idaho Power's service area, expansion or loss of service
area, changes in customer needs and expectations, adoption rates of energy efficiency measures, customer-generated power
such as from rooftop solar panels, demand-side management requirements, regulation or deregulation, and adverse economic
conditions. An economic downturn or recession could also negatively impact customer use and reduce revenues and cash flows,
thus adversely affecting results of operations. Many electric utilities, including Idaho Power, have experienced a decline in
usage per customer, in part attributable to energy efficiency activities. State or federal regulations may be enacted to encourage
or require mandatory energy conservation or technological advances that increase energy efficiency, which could further reduce
usage per customer. Also, changing customer needs and expectations could lead to lower customer satisfaction, reduced loyalty,
difficulty in obtaining rate increases, and customers seeking alternative sources of energy and the unbundling of regulated
electric service. If customers choose to generate their own energy, discontinue a portion or all service from Idaho Power, or
replace electric power for heating with natural gas, demand for Idaho Power's energy may decline and adversely impact the
20
affordability of its services for remaining customers. While Idaho Power has recently experienced a net growth in usage due to
an increase in the number of customers, when adjusted for the impacts of weather, the average monthly usage on a per customer
basis for Idaho residential customers has declined from 1,051 kWh in 2009 to 952 kWh in 2017. Rate mechanisms, such as the
Idaho fixed cost adjustment, are designed to address the financial disincentive associated with promoting energy efficiency
activities, but there is no assurance that the mechanism will result in full or timely collection of Idaho Power's fixed costs,
which are currently collected in large part through the company's volume-based energy rates that are based on historical sales
volume. Any undercollection of fixed costs would adversely impact revenues, earnings, and cash flows. The formation of
municipal utilities or similar entities for distribution systems within Idaho Power's service area could also result in a load
decrease. The loss of loads resulting from some of these events may result in IDACORP and Idaho Power modifying or
eliminating large generation or transmission projects. This could in turn result in reduced revenues as well as write-downs or
write-offs if regulators determine that the costs of the projects were incurred imprudently, which could have a material adverse
impact on IDACORP's and Idaho Power's financial condition, results of operations, and cash flows.
Conversely, if Idaho Power were to experience an unanticipated increase in the demand for energy through, for example, the
rapid addition of new industrial and commercial customers or population growth in the service area, Idaho Power may be
required to rely on higher-cost purchased power to meet peak system demand and may need to accelerate investment in
additional generation or transmission resources. If the incremental costs associated with the unanticipated changes in loads
exceed the incremental revenue received from the sales to the new customers, and Idaho Power is unable to secure timely and
full rate relief to recover those increased costs, the resulting imbalance could have an adverse effect on IDACORP's and Idaho
Power's financial condition, results of operations, and cash flows.
IDACORP's and Idaho Power's operating results fluctuate seasonally and can be adversely affected by changes in weather
conditions and severe weather. Idaho Power's electric power sales are seasonal, with demand in Idaho Power's service area
peaking during the hot summer months, with a secondary peak during the cold winter months. Electric power demands by
irrigation customers in Idaho Power's service area, which are impacted by temperatures and the timing and amount of
precipitation, can also create significant seasonal changes in usage. Seasonality of revenues may be further impacted by Idaho
Power's tiered rate structure, under which rates charged to customers are often higher during higher-load periods, such as hot
summers and cold winters. Market prices for power also often increase significantly during these peak periods, at times when
Idaho Power is required to purchase power in the wholesale markets to meet customer demand. By contrast, when temperatures
are relatively mild or where precipitation supplants irrigation systems, loads are often lower as customers are not using
electricity for heating and air conditioning or irrigation purposes. Thus, weather conditions and the timing and extent of
precipitation can cause IDACORP's and Idaho Power's results of operations and financial condition to fluctuate seasonally,
quarterly, and from year to year.
Changes in climate in Idaho Power's service area could also have significant physical effects, such as increased frequency and
severity of storms, droughts, heat waves, fires, floods, snow loading, and other extreme weather events. These extreme weather
events and their associated impacts can damage transmission, distribution, and generation facilities, causing service
interruptions and extended outages, increasing supply chain costs and other operating and maintenance expenses, and limiting
Idaho Power's ability to meet customer energy demand. Sustained drought conditions or decreased snow pack due to higher
temperatures are likely to decrease power generation from hydroelectric plants. Variations in hydroelectric generation that
increase Idaho Power's reliance on market purchases may lead to more costly power supply sources for its customers and
reduce benefits from selling surplus hydroelectric power in the wholesale market. The price of power in the wholesale energy
markets tends to be higher during periods of high regional demand that tends to occur with weather extremes, which may cause
Idaho Power to purchase power in the wholesale market during peak price periods, increasing power supply costs. The costs of
repair and replacing infrastructure or liability for personal injury or property damage from utility equipment that fails from
significant weather and weather-related events may not be covered in full by insurance. Costs incurred as a result of such events
might also not be recovered through customer rates if the costs incurred are greater than those allowed for recovery by
regulators.
New advances in power generation, energy efficiency, or other technologies that impact the power utility industry could
decrease revenues. The increasing cost of energy in the electric utility industry has encouraged the development of new
technologies for power generation, power storage, and energy efficiency. In particular, in recent years the cost of solar
generation has decreased significantly, and there are federal and state regulations, laws and other incentives in place to help
further reduce the cost of solar generation. There is potential that customer-owned power generation systems, particularly if
coupled with power storage devices, could become sufficiently cost-effective and efficient that an increasing number of Idaho
Power's customers choose to install such systems on their homes or businesses, which in turn could require changes in the way
Idaho Power manages its distribution systems. Additionally, considerable emphasis has been placed on energy efficiency, such
as LED lighting and high-efficiency appliances. Energy efficiency programs, including programs sponsored by Idaho Power
21
under a directive from state regulatory commissions, are designed to reduce energy demand. If Idaho Power is unable to adjust
its rate design or maintain adequate regulatory mechanisms allowing for timely cost recovery, declining usage from customer-
owned generation sources and energy efficiency would result in under-recovery of Idaho Power's costs and investment in
infrastructure, and reduce revenues, which would impact IDACORP's and Idaho Power's financial condition and results of
operations.
Capital expenditures for infrastructure, risks associated with permitting and construction of that infrastructure, and the
timing and availability of cost recovery for the expenditures, can significantly affect IDACORP's and Idaho Power's
financial condition and results of operations. Idaho Power’s business is capital intensive and requires significant investments
in energy generation, transmission, and distribution infrastructure. A significant portion of Idaho Power’s facilities were
constructed many years ago, and thus require periodic upgrades and frequent maintenance. Also, long-term anticipated
increases in both the number of customers and the demand for energy require expansion and reinforcement of that
infrastructure. For instance, Idaho Power is in the permitting process for two 500-kV transmission line projects, which are
intended to help meet future customer energy demands. Construction projects are subject to usual permitting and construction
risks that can adversely affect project costs and the completion time. These risks include, as examples:
•
•
•
•
•
•
•
•
•
the ability to timely obtain labor or materials at reasonable costs;
defaults by contractors;
equipment, engineering, and design failures;
unexpected environmental and geological problems;
the effects of adverse weather conditions;
availability of financing;
load forecasts;
the ability to obtain and comply with permits and land use rights, and environmental constraints; and
delays and costs associated with disputes and litigation with third parties.
The occurrence of any of these risks could cause Idaho Power to operate at reduced capacity levels, which in turn could reduce
revenues, increase expenses, or cause Idaho Power to incur penalties. If Idaho Power is unable or unwilling to complete the
permitting or construction of a project, or incurs costs that regulators do not deem prudent, it may be unable to recover its costs
in full through rates or on a timely basis. Further, if Idaho Power is unable to secure permits or joint funding commitments to
develop transmission infrastructure necessary to serve loads or if other resources become more economical, it may terminate
those projects and, as alternatives, seek to develop additional generation facilities within areas where Idaho Power has available
transmission capacity or pursue other more costly options to serve loads. To limit the timing-related risks of these projects,
Idaho Power may enter into purchase orders and construction contracts and incur engineering and design service costs in
advance of receiving necessary regulatory approvals or permits. If any of the projects are canceled for any reason, including
Idaho Power's failure to receive necessary regulatory approvals or permits or because the project is no longer economical, Idaho
Power could incur significant cancellation penalties under purchase orders or construction contracts. Additionally, termination
of a project carries with it the potential for impairment of the associated asset if regulators deny full recovery of project costs.
Thus, termination of a project could negatively affect IDACORP's and Idaho Power's financial condition and results of
operations.
Changes in legislation, regulation, and government policy may have a material adverse effect on IDACORP’s and Idaho
Power’s business in the future. Changes in, and uncertainty with respect to, federal, state, and local legislation, regulation, and
government policy could significantly impact IDACORP’s and Idaho Power’s businesses and the electric utility industry.
Specific legislative and regulatory proposals and recently enacted legislation that could have a material impact on IDACORP
and Idaho Power include, but are not limited to, tax reform, infrastructure renewal programs, and modifications to public
company reporting requirements and environmental regulation. Further, the proposals and new legislation could have an impact
on the rate of growth of Idaho Power’s customers and their willingness to expand operations and increase electric service
requirements. IDACORP and Idaho Power are monitoring the implementation by federal, state, and local governmental
authorities of various executive orders and are unable to predict whether and to what extent such actions will meaningfully
change existing legislative and regulatory environments relevant to the companies, or if any such changes would have a net
positive or negative impact on the companies. To the extent that such changes have a negative impact on the companies or
Idaho Power’s customers, including as a result of related uncertainty, these changes may materially and adversely impact
IDACORP’s and Idaho Power’s business, financial condition, results of operations, and cash flows.
Changes in income tax laws and regulations, or differing interpretation or enforcement of applicable laws by the U.S.
Internal Revenue Service or other taxing jurisdictions, could have a material adverse impact on IDACORP’s or Idaho
Power’s financial condition and results of operations. IDACORP and Idaho Power must make judgments and interpretations
22
about the application of the law when determining the provision for income taxes. Amounts of income tax-related assets and
liabilities involve judgments and estimates of the timing and probability of recognition of income, deductions, and tax credits,
which are subject to challenge by taxing authorities. In recent years, state regulatory mechanisms with income tax-related
provisions (such as Idaho Power's October 2014 regulatory settlement stipulation with the IPUC), has significantly impacted
IDACORP's and Idaho Power's results of operations. The outcome of ongoing and future income tax proceedings, or the state
public utility commissions' treatment of those outcomes, could differ materially from the amounts IDACORP and Idaho Power
record prior to conclusion of those proceedings, and the difference could negatively affect IDACORP’s and Idaho Power’s
earnings and cash flows. Further, in some instances the treatment from a ratemaking perspective of any net income tax expense
or benefit could be different than IDACORP or Idaho Power anticipate or request from applicable state regulatory commissions,
which could have a negative effect on their financial condition and results of operations. In addition, Idaho Power uses the
regulatory flow-through income tax accounting method as described in Note 1 - "Summary of Significant Accounting Policies"
to the consolidated financial statements included in this report, and potential changes in income tax laws or interpretations may
impact IDACORP's and Idaho Power's income taxes and reporting obligations differently than most other companies.
Due to the enactment of the tax reform act generally referred to as the "Tax Cuts and Jobs Act", which lowered the corporate
federal income tax rate, IDACORP and Idaho Power expect the changes in income tax law to reduce annual income tax expense
for both companies beginning in 2018. However, due to Idaho Power's use of flow-through income tax accounting which has
historically reduced income tax expense and contributed to lower electricity rates for customers, the changes in federal income
tax law may not reduce IDACORP's and Idaho Power's income tax expense as significantly as the income tax expense of some
peers in the utility industry who use fully normalized income tax accounting or non-utility companies. The IPUC has ordered
Idaho Power to record a regulatory liability for the estimated Idaho-jurisdictional share of financial benefits after January 1,
2018, from the changes in federal income tax law, and to file a report with the IPUC identifying and quantifying the income tax
changes along with proposed tariff schedule changes. Idaho Power also filed an application with the OPUC requesting authority
to defer for later ratemaking treatment the Oregon jurisdictional earnings in excess of the currently authorized Oregon
jurisdictional rate of return on equity that may result from the Tax Cuts and Jobs Act as measured from the Company’s annual
Oregon Results of Operations. The OPUC Staff filed an application with the OPUC requesting authority to defer for later
ratemaking treatment the difference between Idaho Power’s current retail rates and its current retail rates inclusive of the impact
of the Tax Cuts and Jobs Act. Idaho Power is working with the IPUC and OPUC to determine how potential income tax
expense reductions from the changes in federal income tax law may benefit Idaho Power customers and affect IDACORP's and
Idaho Power's financial condition and results of operations.
IDACORP's and Idaho Power’s businesses are subject to an extensive set of environmental laws, rules, and regulations,
which could impact their operations and costs of operations, potentially rendering some generating units uneconomical to
maintain or operate, and could increase the costs and alter the timing of major projects. IDACORP's and Idaho Power's
operations are subject to a number of federal, state, and local environmental statutes, rules, and regulations relating to air and
water quality, natural resources, renewable energy, and health and safety. Many of these laws and regulations are described in
Part II - Item 7 - "Management's Discussion and Analysis of Financial Condition and Results of Operations - Environmental
Matters" in this report. These laws and regulations generally require IDACORP and Idaho Power to obtain and comply with a
wide variety of environmental licenses, permits, and other approvals, including through substantial investment in pollution
controls, and may be enforced by both public officials and private individuals. Some of these regulations are pending, changing,
or subject to interpretation, and failure to comply may result in penalties, mandatory operational changes, and other adverse
consequences, including costs associated with defending against claims by governmental authorities or private parties and
complying with new operating requirements. Idaho Power devotes significant resources to environmental monitoring, pollution
control equipment, and mitigation projects to comply with existing and anticipated environmental regulations. However, it is
possible that federal, state and local authorities could attempt to enforce more stringent standards, stricter regulation, and more
expansive application of environmental regulations.
Environmental regulations have created the need for Idaho Power to install new pollution control equipment at, and may cause
Idaho Power to perform environmental remediation on, its owned and co-owned power generation facilities, often at a
substantial cost. Compliance with environmental regulations can significantly increase capital spending, operating costs and
plant outages, and can negatively affect the affordability of Idaho Power's services for customers. Idaho Power cannot predict
with certainty the amount and timing of all future expenditures necessary to comply with, or as a result of liabilities under, these
environmental laws and regulations, although Idaho Power expects the expenditures will be substantial. In some cases, the costs
to obtain permits and ensure facilities are in compliance may be prohibitively expensive. If the costs of compliance with new
regulations renders the generating facilities uneconomical to maintain or operate, Idaho Power would need to identify
alternative resources for power, potentially in the form of new generation and transmission facilities, market power purchases,
demand-side management programs, or a combination of these and other methods. Furthermore, Idaho Power may not be able
23
to obtain or maintain all environmental regulatory approvals necessary for operation of its existing infrastructure or
construction of new infrastructure.
The current presidential administration has issued a number of executive orders related to environmental matters designed to
ease environmental regulation that the federal agencies are still implementing. However, the outcome of the Environmental
Protection Agency's and other federal agencies' review of regulations covered by the executive orders is difficult to predict.
Moreover, the executive orders and any resulting federal regulations could be affected by Congressional action and challenged
in court. Further, state and local governmental authorities could choose to replace the federal regulations or bolster
environmental compliance and enforcement efforts at the local level. Accordingly, Idaho Power may not realize any benefit
from changes to federal environmental regulations, if any, resulting from the executive orders and, as of the date of this report,
cannot predict whether and to what extent the orders could affect its operations and environmental-related expenditures. Idaho
Power is not guaranteed timely or full recovery through customer rates of costs associated with environmental regulations,
environmental compliance, and clean-up of contamination, and regulators may not grant prior approval of cost recovery. If
there is a delay in obtaining any required environmental regulatory approval or if Idaho Power fails to obtain, maintain, or
comply with any such approval, construction and/or operation of Idaho Power's generation or transmission facilities could be
delayed, halted, or subjected to additional costs.
In addition, some environmental regulations are currently subject to litigation and not yet final. As a result of this uncertainty,
strategies to comply with the regulations, including available control technologies or other allowed compliance measures, are
unpredictable and Idaho Power cannot provide any assurance regarding the potential impacts these regulations would have on
Idaho Power's operations or financial condition.
Factors contributing to lower hydroelectric generation can increase costs and negatively impact IDACORP's and Idaho
Power's financial condition and results of operations. Idaho Power derives a significant portion of its power supply from its
hydroelectric facilities. During 2017, 65 percent of Idaho Power's electric power generation was from hydroelectric facilities.
Due to Idaho Power’s heavy reliance on hydroelectric generation, factors such as precipitation and snowpack, the timing of run-
off, and the availability of water in the Snake River basin can significantly affect its operations. The combination of a long-term
trend of declining Snake River base flows, over-appropriation of water, and periods of drought have led to water rights disputes
and proceedings among surface water and ground water irrigators and the State of Idaho. Recharging the Eastern Snake Plain
aquifer by diverting surface water to porous locations and permitting it to sink into the aquifer is one approach to the over-
appropriation dispute. Diversions from the Snake River for aquifer recharge or the loss of water rights reduce Snake River
flows available for hydroelectric generation. When hydroelectric generation is reduced, Idaho Power must increase its use of
more expensive thermal generating resources and market power purchases; therefore, costs increase and opportunities for off-
system sales are reduced, reducing revenues and potentially earnings. Through its power cost adjustment mechanisms, Idaho
Power expects to recover most (but not all) of the increase in net power supply costs caused by lower hydroelectric generation.
The timing of recovery of the increased costs, however, may not occur until the subsequent power cost adjustment year,
adversely affecting cash flows and liquidity.
Obligations imposed in connection with hydroelectric license renewals may require large capital expenditures, increase
operating costs, reduce hydroelectric generation, and negatively affect IDACORP's or Idaho Power's results of operations
and financial condition. For the last several years, Idaho Power has been engaged in an effort to renew its federal license for its
largest hydroelectric generation source, the Hells Canyon Complex. Relicensing includes an extensive public review process
that involves numerous natural resource issues and environmental conditions. The existence of endangered and threatened
species in the watershed may result in major operational changes to the region’s hydroelectric projects, which may be reflected
in hydroelectric licenses, including for the Hells Canyon Complex. In addition, new interpretations of existing laws and
regulations could be adopted or become applicable to hydroelectric facilities, which could further increase required
expenditures for marine life recovery and endangered species protection and reduce the amount of hydroelectric generation
available to meet Idaho Power’s generation requirements. One significant issue identified in connection with the Hells Canyon
Complex relicensing effort involves water temperature gradients in the Snake River below the Hells Canyon dam. Certain
parties in the relicensing proceedings have advocated for the installation of a water temperature management apparatus which,
if required to be installed, would involve substantial costs to construct, operate, and maintain. Idaho Power may be unable to
recover in full or in a timely manner the costs of such an apparatus through rates, particularly given the magnitude of any
potential impact on customer rates. Another significant issue related to the relicensing effort involves a dispute between the
states of Idaho and Oregon regarding whether to reintroduce or establish spawning populations of fish species into Idaho
waters. Idaho Power cannot predict whether and how Idaho and Oregon will negotiate a mutually agreeable approach or
whether legal or regulatory action will ultimately be necessary for such resolution, nor can Idaho Power predict the outcome of
any such proceedings. Idaho Power also cannot predict the requirements that might be imposed during the relicensing process,
the financial impact of those requirements, whether a new multi-year license will ultimately be issued, and whether the IPUC or
24
OPUC will allow recovery through rates of the substantial costs incurred in connection with the licensing process and
subsequent compliance. Imposition of onerous conditions in the relicensing process could result in Idaho Power incurring
significant capital expenditures, increase operating costs (including power purchase costs), and reduce hydroelectric generation,
which could negatively affect results of operations and financial condition.
Idaho Power’s use of coal and natural gas to fuel power generation facilities exposes it to commodity availability and price
risk, which can adversely affect IDACORP's and Idaho Power's results of operations and financial condition. As part of its
normal business operations, Idaho Power purchases coal and natural gas in the open market or under short-term or long-term
contracts, often with variable pricing terms. Market prices for coal and natural gas are volatile and influenced by factors
impacting supply and demand such as weather conditions, fuel transportation availability, economic conditions, and changes in
technology. Natural gas transportation to Idaho Power's three natural gas plants is limited to one primary pipeline, presenting a
heightened possibility of supply constraint and disruptions separate from the risk of counterparty default. Most of Idaho Power's
coal supply arrangements are under long-term contracts for coal originating in Wyoming, and thus Idaho Power is exposed to
risk of disruption of coal production in, or transportation from, that region. Idaho Power may from time to time enter into new,
or renegotiate, these long-term contracts but can provide no assurance that such contracts will be negotiated or renegotiated on
satisfactory terms, or at all. There also can be no assurance that counterparties to the natural gas or coal supply agreements will
fulfill their obligations to supply natural gas or coal, and they may experience financial or technical problems or unforeseeable
events that inhibit their ability to deliver natural gas or coal. Defaults by coal and natural gas suppliers may cause Idaho Power
to seek alternative, and potentially more costly, sources of fuel or rely on other generation sources or wholesale market power
purchases. Idaho Power may not be able to fully or timely recover these increased costs through rates, which may adversely
affect IDACORP's and Idaho Power's financial condition and results of operations.
If the assumptions underlying coal mine reclamation at Bridger Coal Company and related forecast trust fund growth are
materially inaccurate, Idaho Power’s costs could be greater than anticipated or be incurred sooner than anticipated. Bridger
Coal Company, a subsidiary of Idaho Power, uses both surface and underground methods to mine coal to be used for power
generation at the Jim Bridger power plant. The federal Surface Mining Control and Reclamation Act and state laws and
regulations establish operational, reclamation, bonding, and closure obligations and standards for mining of coal. Bridger Coal
Company’s estimate of reclamation liability and bonding obligations is reviewed periodically by Idaho Power’s management
committee and by government regulators. Idaho Power funds a trust to cover such projected mine reclamation costs. The trust
funds are invested in debt and equity securities and poor performance of these investments would reduce the amount of funds
available for their intended purpose, which could require Idaho Power to make additional cash contributions. If actual costs
related to those obligations exceed estimates, government regulations relating to those obligations change significantly or
unexpected cash funding obligations are required, IDACORP’s and Idaho Power’s results of operations and financial condition
could be adversely affected.
Idaho Power’s generation, transmission, and distribution facilities are subject to numerous operational risks unique to it
and its industry. Operating risks associated with Idaho Power's generation, transmission, and distribution facilities include
equipment failures, volatility in fuel and transportation pricing, interruptions in fuel supplies, increased regulatory compliance
costs, labor disputes, accidents and workforce safety matters, release of hazardous or toxic substances into the air, water, or
ground, wildfires, acts of terrorism or sabotage, the loss of cost-effective disposal options for solid waste such as coal ash,
operator error, and the occurrence of catastrophic events at the facilities. Diminished availability or performance of those
facilities could result in reduced customer satisfaction, reputational harm, liability to third parties, and regulatory inquiries and
fines. Operation of Idaho Power's owned and co-owned generating stations below expected capacity levels, or unplanned
outages at these stations, could cause reduced energy output and lower efficiency levels and result in lost revenues and
increased expenses for alternative fuels or wholesale market power purchases. Further, the transmission system in Idaho
Power's service area is constrained, limiting the ability to transmit electric energy within the service area and access electric
energy from outside the service area during high-load periods. Idaho Power's transmission facilities are also interconnected with
those of third parties, and thus operation of Idaho Power's and third parties' facilities could be adversely affected by unexpected
or uncontrollable events. These transmission constraints and events could result in failure to provide reliable service to
customers and the inability to deliver energy from generating facilities to the power grid, and the inability to access lower cost
sources of electric energy.
Accidents, electrical contacts, fires, explosions, catastrophic failures, general system damage or dysfunction, uncontrolled
release of water from hydroelectric dams, and other unplanned events related to Idaho Power's infrastructure would increase
repair costs and may expose Idaho Power to liability for personal injury and property damage. Fires alleged to have been caused
by Idaho Power's transmission, distribution, or generation infrastructure could also expose Idaho Power to claims for fire
suppression costs and liability for personal injury or property damage, whether based on claims of negligence, trespass or
otherwise. Idaho Power maintains insurance coverage for such operating and event risks, but insurance coverage is subject to
25
the terms and limitations of the available policies and may not be sufficient to cover Idaho Power’s ultimate liability. If the
amount of insurance is insufficient or otherwise unavailable, or if Idaho Power is unable to recover in rates the costs of any
uninsured losses, IDACORP’s and Idaho Power’s financial condition, results of operations, or cash flows could be materially
affected.
Volatility or disruptions in the financial markets, failure of IDACORP or Idaho Power to satisfy conditions necessary for
obtaining loans or issuing debt securities, and denial of regulatory authority to issue debt or equity securities may negatively
affect IDACORP’s and Idaho Power’s ability to access capital and/or increase their cost of borrowing, and ability to execute
on their strategic plans. IDACORP and Idaho Power use credit facilities, commercial paper markets, and long-term debt as
significant sources of liquidity and funding for operating and capital requirements and debt maturities not satisfied by operating
cash flow. The credit facilities represent commitments by the participating banks to make loans and issue letters of credit.
However, the ability and obligation of the participating banks to make those loans and issue letters of credit is subject to
specified conditions and volatility or disruptions in the financial markets could affect the companies' ability to obtain debt
financing or draw upon or renew existing credit facilities. Idaho Power's ability to issue long-term debt is also subject to a
number of conditions included in an indenture, and Idaho Power's ability to issue long-term debt and commercial paper is
subject to the availability of purchasers willing to purchase the securities under reasonable terms or at all. Because of these
limitations, IDACORP and Idaho Power may be unable to issue commercial paper or short-term or long-term debt at reasonable
interest rates and terms or at all. Also, while the credit facilities represent a contractual obligation to make loans, one or more of
the participating banks may default on their obligations to make loans under, or may withdraw from, the credit facilities.
Idaho Power is required to obtain regulatory approval in Idaho, Oregon, and Wyoming in order to borrow money or to issue
securities and is therefore dependent on the public utility commissions of those states to issue favorable orders in a timely
manner to permit them to finance their operations, capital expenditures, and debt maturities. IDACORP's and Idaho Power's
credit facilities include financial covenants that limit the amount of debt that can be outstanding as a percentage of total capital,
and Idaho Power's long-term debt has also been issued under an indenture that contains a number of financial covenants. The
companies must also make specified representations in connection with request for loans and it is possible that they may be
unable to do so at the time of such request, which would limit or eliminate the obligation of the banks to provide loans. Failure
to maintain these representations and covenants could preclude IDACORP and Idaho Power from issuing commercial paper,
borrowing under their credit facilities, or issuing long-term debt, and could trigger a default and repayment obligation under
debt instruments, which could limit their ability to pursue certain projects and adversely impact IDACORP's and Idaho Power's
financial condition, results of operations, and liquidity.
A downgrade in IDACORP’s and Idaho Power’s credit ratings could affect the companies’ ability to access capital, increase
their cost of borrowing, and require the companies to post collateral with transaction counterparties. Credit rating agencies
periodically review the corporate credit ratings and long-term ratings of IDACORP and Idaho Power. These ratings are
premised on financial ratios and performance, the regulatory environment and rate mechanisms, the effectiveness of
management, resource risks and power supply costs, and other factors. IDACORP and Idaho Power also have borrowing
arrangements that rely on the ability of the banks to fund loans or support commercial paper, a principal source of short-term
financing. Downgrades of IDACORP’s or Idaho Power’s credit ratings, or those affecting relationship banks, could limit the
companies’ ability to access short- and long-term capital under reasonable terms or at all, reduce the pool of potential lenders,
increase borrowing costs under existing credit facilities, limit access to the commercial paper market, require the companies to
pay a higher interest rate on their debt, and require the companies to post additional performance assurance collateral with
transaction counterparties. If access to capital were to become significantly constrained or costs of capital increased
significantly due to lowered credit ratings, prevailing industry conditions, regulatory constraints, the volatility of the capital
markets or other factors, IDACORP's and Idaho Power's financial condition and results of operations could be adversely
affected.
Idaho Power’s risk management policy and programs relating to economically hedging commodity exposures and credit risk
may not always perform as intended, and as a result, IDACORP and Idaho Power may suffer economic losses. Idaho Power
enters into transactions to hedge its positions in coal, natural gas, power, and other commodities, and enters into financial hedge
transactions to mitigate in part exposure to variable commodity prices. IDACORP and Idaho Power could recognize financial
losses as a result of volatility in the market value of these contracts or if a counterparty fails to perform. The derivative
instruments used for hedging might not offset the underlying exposure being mitigated as intended, due to pricing inefficiencies
or other terms of the derivative instruments, and any such failure to mitigate exposure could result in financial losses. Certain of
Idaho Power's hedging and derivative agreements may result in the receipt of, or posting of, collateral with counterparties.
Fluctuations in commodity prices that lead to the posting of collateral with counterparties negatively impact liquidity, and
downgrades in Idaho Power's credit ratings may lead to additional collateral posting requirements. Further, forecasts of future
fuel needs and loads and available resources to meet those loads are inherently uncertain and may cause Idaho Power to over-
26
or under-hedge actual resource needs, exposing the company to market risk on the over- or under-hedged position. To the extent
that commodity markets are illiquid, Idaho Power may not be able to execute its risk management strategies, which could result
in undesired over-exposure to unhedged positions. As a result, risk management actions, or the failure or inability to manage
commodity price and counterparty risk, may adversely affect IDACORP’s and Idaho Power’s financial condition and results of
operations.
Idaho Power could be subject to penalties and operational changes if it violates mandatory reliability and security
requirements, which could adversely impact IDACORP's and Idaho Power's results of operations and financial condition.
As an owner and operator of a bulk power transmission system, Idaho Power is subject to mandatory reliability and security
standards issued by the North American Electric Reliability Corporation and enforced by the FERC. The standards are based on
the functions that need to be performed to ensure the bulk power system operates reliably and are guided by reliability and
market interface principles. Compliance with reliability standards subjects Idaho Power to higher operating costs and increased
capital expenditures. Idaho Power has received in recent years notices of violations from, and regularly self-reports reliability
standard compliance issues to, the FERC, the North American Electric Reliability Corporation, and the Western Electricity
Coordinating Council. Potential monetary and non-monetary penalties for a violation of FERC regulations may be substantial,
and in some circumstances monetary penalties may be as high as $1 million per day per violation. The FERC may take action to
limit volatility in the energy market by imposing price limits or other market restrictions to control market-based rate sales,
which could adversely affect the companies' financial results. The imposition of penalties on Idaho Power for its actual or
alleged failure to comply with reliability and security requirements could also have a negative effect on its and IDACORP’s
results of operations and financial condition.
Federally mandated purchases of power from renewable energy projects, and integration of power generated from those
projects into Idaho Power's system, may increase costs and decrease system reliability, and adversely affect Idaho Power's
and IDACORP's results of operations and financial condition. An abundance of intermittent, non-dispatchable generation
from renewable energy projects interconnected with Idaho Power's system has had an impact on the operation of Idaho Power's
generation plants, system reliability, power supply costs, and the wholesale power markets in the Pacific Northwest. Idaho
Power is generally obligated under federal law to purchase power from certain renewable energy projects, regardless of the
then-current load demand, availability of lower cost generation resources, or wholesale energy market prices. This increases the
likelihood and frequency that Idaho Power will be required to reduce output from its lower-cost hydroelectric and fossil fuel-
fired generation resources, which in turn increases power purchase costs and customer rates and impacts Idaho Power's ability
to invest in additional generation. Increases in customer rates could make self-generation more financially attractive for
customers, which could result in reduced net load and shifts in customer costs. Further, balancing load and generation from
Idaho Power's power generation portfolio is challenging, and Idaho Power expects that its operational costs will continue to
increase as a result of its efforts to integrate intermittent, non-dispatchable generation from a large number of renewable energy
projects. If Idaho Power is unable to timely recover those costs through its power cost adjustment mechanisms or otherwise,
those increased costs may negatively affect IDACORP's and Idaho Power's results of operations, financial condition, and cash
flows.
The performance of pension and postretirement benefit plan investments and other factors impacting plan costs and funding
obligations could adversely affect IDACORP's and Idaho Power's financial condition and results of operations - primarily
cash flows and liquidity. Idaho Power provides a noncontributory defined benefit pension plan covering most employees, as
well as a defined benefit postretirement benefit plan (consisting of health care and death benefits) that covers eligible retirees.
Costs of providing these benefits are based in part on the value of the plans' assets and, therefore, adverse investment
performance for these assets or the failure to maintain sustained growth in pension investments over time could increase Idaho
Power’s plan costs and funding requirements related to the plans. As benefit costs continue to rise, there is no assurance that the
state public utility commissions will continue to allow recovery. The key actuarial assumptions that affect funding obligations
are the expected long-term return on plan assets and the discount rate used in determining future benefit obligations. Idaho
Power evaluates the actuarial assumptions on an annual basis, taking into account changes in market conditions, trends, and
future expectations. Estimates of future equity and debt market performance, changes in interest rates, and other factors Idaho
Power and its actuary firms use to develop the actuarial assumptions are inherently uncertain, and actual results could vary
significantly from the estimates. Changes in demographics, including timing of retirements or changes in life expectancy
assumptions, may also increase Idaho Power's plan costs and funding requirements. Future pension funding requirements and
the timing of funding payments are also subject to the impacts of changes in legislation. Depending on the timing of
contributions to the plans and Idaho Power's ability to recover costs through rates, cash contributions to the plans could reduce
the cash available for the companies' businesses and payment of dividends. For additional information regarding Idaho Power's
funding obligations under its benefit plans, see Note 11 - "Benefit Plans" to the consolidated financial statements included in
this report.
27
As a holding company, IDACORP does not have its own operating income and must rely on the cash flows from its
subsidiaries to pay dividends and make debt payments. IDACORP is a holding company with no significant operations of its
own, and its primary assets are shares or other ownership interests of its subsidiaries, primarily Idaho Power. IDACORP’s
subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts to IDACORP, whether through
dividends, loans, or other means. The ability of IDACORP’s subsidiaries to pay dividends or make distributions to IDACORP
depends on several factors, including each subsidiary's actual and projected earnings and cash flow, capital requirements and
general financial condition, regulatory restrictions, tax obligations, covenants contained in credit facilities to which they are
parties, and the prior rights of holders of their existing and future first mortgage bonds and other debt or equity securities.
Further, the amount and payment of dividends is at the discretion of the board of directors, which may reduce or cease payment
of dividends at any time. See Note 6 - "Common Stock" to the consolidated financial statements included in this report for a
further description of restrictions on IDACORP's and Idaho Power's payment of dividends.
IDACORP's and Idaho Power's activities are concentrated in one industry and in one region, which exposes it to risks from
lack of diversification, regional economic conditions, and regional legislation and regulation. IDACORP and Idaho Power
do not have diversified operations or sources of revenue. Idaho Power comprises the bulk of IDACORP's operations, and Idaho
Power's business is concentrated solely in the electricity industry. Furthermore, Idaho Power's provision of electric service to
retail customers is conducted exclusively in its southern Idaho and eastern Oregon service area. As a result, IDACORP's and
Idaho Power's future performance will be affected by economic conditions, regulatory and legislative activity, and other events
in its service area and in the electric power industry.
The impacts of a retiring workforce with specialized utility-specific functions could increase costs and adversely affect
IDACORP's and Idaho Power's financial condition and results of operations. Idaho Power’s operations require a skilled
workforce to perform specialized utility functions. Many of these positions, such as linemen, grid operators, engineering and
design personnel, and generation plant operators, require extensive, specialized training. Idaho Power has experienced in recent
years an above-average number of employee retirements and expects the increased level of retirement of its skilled workforce
and persons in key positions will continue in 2018 and in the near-term. At December 31, 2017, approximately 23 percent of
Idaho Power's employees were eligible for regular or early retirement under Idaho Power's defined benefit pension plan. This
will require Idaho Power to attract, train, and retain new employees to help prevent a loss of institutional knowledge and avoid
a skills gap. The loss of skills and institutional knowledge of experienced employees and the failure to hire and the costs
associated with attracting, training, and retaining appropriately qualified employees to replace an aging and skilled workforce
could have a negative effect on IDACORP's and Idaho Power's financial condition and results of operations.
IDACORP and Idaho Power are subject to costs and other effects of legal and regulatory proceedings, disputes, and claims.
From time to time in the normal course of business, IDACORP and Idaho Power are subject to various lawsuits, regulatory
proceedings, disputes, and claims that could result in adverse judgments or settlements, fines, penalties, injunctions, or other
adverse consequences. These matters are subject to a number of uncertainties, and management is often unable to predict the
outcome of such matters; resulting liabilities could exceed amounts currently reserved or insured against with respect to such
matter. The legal costs and final resolution of matters in which IDACORP or Idaho Power are involved could have reputational
impact and a short- or long-term negative effect on their financial condition and results of operations. Similarly, the terms of
resolution could require the companies to change their operational practices and procedures, which could also have a negative
effect on their financial positions and results of operations.
Acts or threats of terrorism, cyber attacks, data or physical security breaches, and other acts of individuals or groups seeking
to disrupt Idaho Power's operations or the electric power grid could require significant expenditures, or result in claims
against the companies, and negatively impact IDACORP's and Idaho Power's financial condition and results of operations.
Idaho Power operates in an industry that requires the continuous use and operation of sophisticated information technology
systems and network infrastructure. Idaho Power's generation and transmission facilities and its grid operations are potential
targets for terrorist acts and threats, as well as cyber attacks and other disruptive activities of individuals or groups. Some of
Idaho Power's facilities are deemed "critical infrastructure," in that incapacity or destruction of the facilities could have a
debilitating impact on security, reliability or operability of the bulk electric power system, national economic security, and
public health and safety. The possibility that infrastructure facilities, such as generation facilities and electric transmission
facilities, would be direct targets of, or indirect casualties of, an act of terror or cyber attack (whether originating internally or
externally) may affect Idaho Power's operations by limiting the ability to generate, purchase, or transmit power. Cyber threats
and attacks can have cascading impacts that unfold with increasing speed across networks, information systems and other
technologies. Network, information systems and technology-related events, including those caused by us, such as process
breakdowns, security architecture or design vulnerabilities, or by third parties, such as computer hackings, cyber attacks,
computer viruses, worms or other destructive or disruptive software, denial of service attacks, malicious social engineering or
other malicious activities, or any combination of the foregoing, or power outages, natural disasters, infectious disease
28
outbreaks, terrorist attacks or other similar events, could result in a degradation or disruption of the products and services of the
companies. These events, and governmental actions in response, could result in a material decrease in revenues and increase
costs to protect, repair, and insure Idaho Power's assets and operate its business.
Federal regulators have stated that a number of organizations continue to seek opportunities to exploit potential vulnerabilities
in the U.S. energy infrastructure and that those attacks have become increasingly sophisticated. Attacks on Idaho Power's
infrastructure could result from acts of those organizations or other third parties as well as Idaho Power employees or
contractors. At the same time, Idaho Power's energy infrastructure is becoming more reliant on network-based infrastructure.
Idaho Power's operations require the continuous availability of information technology systems and network infrastructure, and
in the normal course of business, Idaho Power collects sensitive and confidential customer and employee information and
proprietary information of Idaho Power. Although Idaho Power actively monitors developments in cyber security, no security
measures can completely shield Idaho Power's systems, infrastructure, and data from vulnerabilities to cyber attacks, intrusions,
or other catastrophic events that could result in their failure or reduced functionality, and ultimately the potential loss of
sensitive information or the loss of Idaho Power's ability to fulfill critical business functions and provide reliable electric power
to customers. Any security breaches, such as misappropriation, misuse, leakage, falsification or accidental release or loss of
information maintained in IDACORP's and Idaho Power's information technology systems, including customer data, could
result in violations of privacy and other laws, financial loss to Idaho Power or to its customers, customer dissatisfaction, and
significant litigation and penalty exposure, all of which could materially affect Idaho Power's financial condition and results of
operations.
Changes in accounting standards or rules may impact IDACORP's and Idaho Power's financial results and disclosures. The
Financial Accounting Standards Board and the SEC may make changes to accounting standards that impact presentation and
disclosures of financial condition and results of operations. Further, new accounting orders issued by the FERC could
significantly impact IDACORP's and Idaho Power's reported financial condition. Idaho Power meets conditions under generally
accepted accounting principles (GAAP) to reflect the impact of regulatory decisions in its financial statements and to defer
certain costs as regulatory assets until those costs are collected in rates, and to defer some items as regulatory liabilities. If
recovery of these amounts ceases to be probable, if Idaho Power determines that it no longer meets the criteria for applying
regulatory accounting, or if accounting rules change to no longer provide for regulatory assets and liabilities, Idaho Power
could be required to eliminate some or all of those regulatory assets or liabilities. Any of these circumstances could result in
write-offs and have a material effect on IDACORP's and Idaho Power’s financial condition and results of operations.
None.

PART II
ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND
ISSUER PURCHASES OF EQUITY SECURITIES
IDACORP’s common stock, without par value, is traded on the New York Stock Exchange (NYSE) under the trading symbol
"IDA". On February 16, 2018, there were 9,340 holders of record of IDACORP common stock and the closing stock price was
$85.27 per share. The outstanding shares of Idaho Power’s common stock, $2.50 par value, are held by IDACORP and are not
traded. IDACORP became the holding company of Idaho Power on October 1, 1998.
IDACORP and Idaho Power paid dividends of $113 million, $105 million, and $97 million in 2017, 2016, and 2015,
respectively. The amount and timing of dividends paid on IDACORP’s common stock are within the discretion of IDACORP’s
board of directors, subject to other restrictions. The board of directors reviews the dividend rate quarterly to determine its
appropriateness in light of IDACORP’s current and long-term financial position and results of operations, capital requirements,
rating agency requirements, contractual and regulatory restrictions, legislative and regulatory developments affecting the
electric utility industry in general and Idaho Power in particular, competitive conditions, and any other factors the board of
directors deems relevant. The ability of IDACORP to pay dividends on its common stock is dependent upon dividends paid to it
by its subsidiaries, primarily Idaho Power. The IDACORP board of directors has a dividend policy for IDACORP that provides
for a target long-term dividend payout ratio of between 50 and 60 percent of sustainable IDACORP earnings, with the
flexibility to achieve that payout ratio over time and to adjust the payout ratio or to deviate from the target payout ratio from
time to time based on the various factors that drive the board of director's dividend decisions. IDACORP's dividends during
2017 were 53 percent of actual 2017 earnings. Notwithstanding the dividend policy adopted by IDACORP's board of directors,
the dividends IDACORP pays remain in the discretion of the board of directors who, when evaluating the dividend amount, will
take into account the foregoing factors, among others.
IDACORP's and Idaho Power's payment of dividends is subject to a number of restrictions. For information relating to those
restrictions, see Note 6 - “Common Stock” to the consolidated financial statements included in this report.

INTRODUCTION
IDACORP is a holding company whose principal operating subsidiary is Idaho Power. IDACORP’s common stock is listed and
trades on the New York Stock Exchange under the trading symbol "IDA". Idaho Power is an electric utility whose rates and
other matters are regulated by the Idaho Public Utilities Commission (IPUC), Public Utility Commission of Oregon (OPUC),
and Federal Energy Regulatory Commission (FERC). Idaho Power generates revenues and cash flows primarily from the sale
and distribution of electricity to customers in its Idaho and Oregon service territories, as well as from the wholesale sale and
transmission of electricity.
Idaho Power is the parent of IERCo, a joint venturer in BCC, which mines and supplies coal to the Jim Bridger generating plant
owned in part by Idaho Power. IDACORP’s other notable subsidiaries include IFS, an investor in affordable housing and other
real estate investments; and Ida-West Energy Company, an operator of small hydroelectric generation projects that satisfy the
requirements of the PURPA.
EXECUTIVE OVERVIEW
IDACORP is committed to its focus on competitive total returns and generating long-term value for shareholders. IDACORP’s
business strategy emphasizes Idaho Power as IDACORP’s core business, as Idaho Power’s regulated electric utility operations

IDACORP's 2017 net income increased $14.1 million compared with 2016, primarily from higher net income at Idaho Power.
Customer growth in 2017 contributed to an increase in Idaho Power's operating income of $9.2 million compared with 2016, as
the number of Idaho Power customers grew by 2.0 percent over 2016. Warmer summer temperatures and colder winter
temperatures during 2017 compared with 2016 led to increased sales volumes on a per-customer basis, primarily for residential
customers using energy for heating and cooling. The increased residential sales volumes resulted in residential sales making up
a larger portion of the sales mix and contributed to a greater proportion of residential sales in higher rate categories under Idaho
Power's tiered rate structure. Higher levels of commercial and industrial activity in Idaho Power's service area also led to an
increase in sales volumes on a per customer basis for commercial and industrial customers. Higher usage per customer in 2017
compared with 2016 increased Idaho Power's operating income by $9.9 million during that period. The FCA mechanism
reduced operating income by $12.1 million during 2017 compared with 2016, as the increased usage per customer led to less
FCA revenue needed to recover fixed costs. The Valmy Plant settlement stipulation described below in this MD&A, along with
the residential sales changes noted above, led to a $34.1 million increase in operating income due to the resulting increase in
revenues per MWh.
During 2017, Idaho Power benefited from an $11.9 million increase in transmission wheeling and other revenue compared with
2016. This change was primarily due to an increase in wheeling volumes, an increase in Idaho Power's OATT rates, and a new
long-term wheeling agreement that became effective in July 2016.
35
In 2017, the IPUC and OPUC each approved settlement stipulations related to Idaho Power’s plan to end its participation in
coal-fired operations at the Valmy Plant by the end of 2025. The settlement stipulations resulted in increased general business
revenues in 2017, increased net depreciation expense, and increased associated income tax expense, including plant-related
flow-through tax adjustments. Most of the $34.1 million increase in "Revenues per MWh, net of associated power supply costs
and power cost adjustment mechanisms" in the table above reflects the increase in general business revenues from the Valmy
Plant settlement stipulations and most of the $18.4 million increase in "Depreciation expense" in the table above reflects the
increase in depreciation expense. Compared with Idaho Power’s estimate of what ongoing net income would have been without
the settlement stipulations, the settlement stipulations are expected to increase after-tax net income by approximately $5 million
on an annual basis. Idaho Power expects the ongoing annual benefit to net income from the Valmy Plant settlement stipulations
to decline slightly each year through 2028, primarily due to the annual decline in Valmy Plant-related rate base, which is
expected to be fully depreciated by December 31, 2028.
O&M expenses decreased $2.2 million in 2017 compared with 2016, primarily due to a $2.4 million benefit related to
previously expensed energy efficiency rider-funded costs deemed to be prudently incurred as further discussed in "Regulatory
Matters" in this MD&A, and a $2.7 million decrease in thermal O&M expenses due to lower generation at thermal plants.
These decreases in O&M were partially offset by a $2.5 million increase in O&M related to a pending settlement stipulation in
Idaho that established the reasonableness of HCC relicensing costs incurred through December 2015 as further discussed in
"Regulatory Matters" in this MD&A.
Changes in non-operating income and expenses, net, reduced operating income by $2.8 million when compared with 2016,
primarily related to a decrease in allowance for funds used during construction (AFUDC). In 2017, Idaho Power reduced
AFUDC by $2.5 million related to the pending HCC settlement stipulation noted above.
Idaho Power's income tax expense was higher in 2017 compared with 2016, primarily due to higher pre-tax income and the
$5.6 million flow-through benefit of tax deductible make-whole premiums that Idaho Power paid in connection with the early
redemption of long-term debt in 2016. There were no early redemptions of long-term debt in 2017. These increases in income
tax expense were partially offset by greater net flow-through income tax items at Idaho Power.
IDACORP's 2016 net income also included $3.7 million of income, net of tax, which was the result of a December 2016
settlement relating to the California energy market proceedings.
2018 Initiatives and Strategy
IDACORP and Idaho Power’s strategy is focused on four strategic areas of growing to enhance financial strength, improving
Idaho Power's core business, enhancing Idaho Power’s brand, and focusing on safety and employee engagement. IDACORP's
board of directors has reviewed and affirmed IDACORP’s and Idaho Power's long-term strategy. In executing on these four
strategic focus areas, IDACORP seeks to balance the interests of shareowners, Idaho Power customers, employees, and other
stakeholders. Idaho Power is working to continue to provide safe, affordable, reliable service to its customers from a diversified
source of generation resources, with a continued commitment to strong, sustainable financial results. For more information on
the business strategy of the companies, see Part I, Item 1 – “Business - Business Strategy” in this report.
Overview of General Factors and Trends Affecting Results of Operations and Financial Condition
IDACORP's and Idaho Power's results of operations and financial condition are affected by a number of factors, and the impact
of those factors is discussed in more detail below in this MD&A. To provide context for the discussion elsewhere in this report,
some of the more notable factors include the following:
• Tax Cuts and Jobs Act: On December 22, 2017, the tax reform act generally referred to as the "Tax Cuts and Jobs Act"
was signed into law, which lowered the corporate federal income tax rate from 35 percent to 21 percent and modified
or eliminated certain federal income tax deductions for corporations. The majority of the law changes, including the
rate reduction, became effective on January 1, 2018. IDACORP and Idaho Power expect the changes in income tax
law to reduce annual income tax expense for both companies beginning in 2018. Due to Idaho Power's use of
regulatory flow-through income tax accounting which has historically reduced income tax expense and contributed to
lower electricity rates for customers, the changes in federal income tax law may not reduce IDACORP's and Idaho
Power's income tax expense as significantly as some peers in the utility industry who use fully normalized income tax
accounting or non-utility companies. Idaho Power is working with the IPUC and OPUC to determine how potential
income tax expense reductions from the changes in federal income tax law may benefit Idaho Power customers and
affect IDACORP's and Idaho Power's financial condition and results of operations. The method through which
potential cost savings may be accrued for the benefit of customers, including potential reductions to customer rates and
36
to regulatory deferrals, will require approval from the IPUC and OPUC. Refer to "Regulatory Matters" in this MD&A
for more information on the related regulatory proceedings.
• Regulation of Rates and Cost Recovery: The price that Idaho Power is authorized to charge for its electric and
transmission service is a critical factor in determining IDACORP's and Idaho Power's results of operations and
financial condition. Those rates are established by state regulatory commissions and the FERC, and are intended to
allow Idaho Power an opportunity to recover its expenses and earn a reasonable return on investment. Because of the
significant impact of ratemaking decisions, and in pursuit of its goal of advancing a purposeful regulatory strategy,
Idaho Power focuses on timely recovery of its costs through filings with the company's regulators, working to put in
place innovative regulatory mechanisms, and on the prudent management of expenses and investments. Idaho Power
has a regulatory settlement stipulation in Idaho that includes provisions for the accelerated amortization of certain tax
credits to help achieve a minimum 9.5 percent return on year-end equity in the Idaho jurisdiction (Idaho ROE). The
settlement stipulation also provides for the potential sharing between the company and customers of Idaho-
jurisdictional earnings in excess of specified levels of Idaho ROE. The specific terms of the settlement stipulation are
described in "Regulatory Matters" in this MD&A and in Note 3 - "Regulatory Matters" to the consolidated financial
statements included in this report. During 2018, Idaho Power will continue to assess the need to file a general rate case
to reset base rates.
• Economic Conditions and Loads: Economic conditions impact consumer demand for electricity and revenues,
collectability of accounts, the volume of off-system sales, and the need to construct and improve infrastructure,
purchase power, and implement programs to meet customer load demands. In recent years, Idaho Power has seen
growth in the number of customers in its service area. In 2017, Idaho Power's customer count grew by 2.0 percent, and
employment in Idaho Power's service area grew by approximately 3.7 percent based on Idaho Department of Labor
preliminary December 2017 data. Idaho Power expects its number of customers to continue to increase in the
foreseeable future. Idaho Power has in recent years supported State of Idaho-coordinated efforts to promote economic
development with an emphasis on attracting industrial and commercial customers to its service area.
In June 2017, Idaho Power filed its Integrated Resource Plan (2017 IRP), Idaho Power's long-term forecast of loads
and resources. The load forecast assumptions Idaho Power used in the 2017 IRP are included in the table below. For
comparison purposes, the analogous average annual growth rates used in the prior two IRPs are included.

• Rate Base Growth and Infrastructure Investment: As noted above, the rates established by the IPUC and OPUC are
determined so as to provide an opportunity for Idaho Power to recover authorized operating expenses and earn a
reasonable return on “rate base.” Rate base is generally determined by reference to the original cost (net of
accumulated depreciation) of utility plant in service, subject to various adjustments for deferred taxes and other items.
Over time, rate base is increased by additions to utility plant in service and reduced by depreciation and retirement of
utility plant and write-offs as authorized by the IPUC and OPUC. In recent years, Idaho Power has been pursuing
significant enhancements to its utility infrastructure, including major ongoing transmission projects such as the
Boardman-to-Hemingway and Gateway West projects, in an effort to ensure an adequate supply of electricity, to
provide service to new customers, and to maintain system reliability. Idaho Power's existing hydroelectric and thermal
generation facilities also require continuing upgrades and component replacement, and the company is undertaking a
significant relicensing effort for the HCC, its largest hydroelectric generation resource. Idaho Power expects to include
completed capital projects in its next general rate case or, in circumstances where appropriate, a single-issue rate case
for individual projects with a significant capital cost. Depending on the outcome of the regulatory process and items
such as the rate of return authorized by the IPUC and OPUC, this growth in rate base has the potential to increase
Idaho Power's revenues and earnings.
• Weather Conditions: Weather and agricultural growing conditions have a significant impact on Idaho Power's energy
sales. Relatively low and high temperatures result in greater energy use for heating and cooling, respectively. During
the agricultural growing season, which in large part occurs during the second and third quarters, irrigation customers
37
use electricity to operate irrigation pumps, and weather conditions can impact the timing and extent of use of those
pumps. Idaho Power also has tiered rates and seasonal rates, which contribute to increased revenues during higher-load
periods, most notably during the third quarter of each year, when overall customer demand is highest. Much of the
adverse or favorable impact of weather on sales of energy to residential and small commercial customers is mitigated
through the Idaho FCA mechanism.
Further, as Idaho Power's hydroelectric facilities comprise nearly one-half of Idaho Power's nameplate generation
capacity, precipitation levels impact the mix of Idaho Power's generation resources. When hydroelectric generation is
reduced, Idaho Power must rely on more expensive generation sources and purchased power. When favorable
hydroelectric generating conditions exist for Idaho Power, they also may exist for other Pacific Northwest
hydroelectric facility operators, lowering regional wholesale market prices and impacting the revenue Idaho Power
receives from off-system sales of its excess power. Much of the adverse or favorable impact of this volatility is
addressed through the Idaho and Oregon power cost adjustment mechanisms.
• Mitigation of Impact of Fuel and Purchased Power Expense: In addition to hydroelectric generation, Idaho Power
relies significantly on natural gas and coal to fuel its generation facilities and power purchases in the wholesale
markets. Fuel costs are impacted by electricity sales volumes, the terms of contracts for fuel, Idaho Power's generation
capacity, the availability of hydroelectric generation resources, transmission capacity, energy market prices, and Idaho
Power's hedging program for managing fuel costs. Recently, low natural gas prices have made operation of Idaho
Power's natural gas power plants more economical, resulting in increased operation of those plants and decreased
operation of coal-fired plants. Purchased power costs are impacted by the terms of contracts for purchased power, the
rate of expansion of alternative energy generation sources such as wind or solar energy, and wholesale energy market
prices. The Idaho and Oregon power cost adjustment mechanisms mitigate in large part the potential adverse impacts
of fluctuations in power supply costs to Idaho Power.
• Regulatory and Environmental Compliance Costs: Idaho Power is subject to extensive federal and state laws,
policies, and regulations, as well as regulatory actions and audits by agencies and quasi-governmental agencies,
including the FERC, the North American Electric Reliability Corporation, and Western Electricity Coordinating
Council. Compliance with these requirements directly influences Idaho Power's operating environment and affects
Idaho Power's operating costs. Environmental laws and regulations, in particular, may increase the cost of operating
generation plants and constructing new facilities, require that Idaho Power install additional pollution control devices
at existing generating plants, or require that Idaho Power cease operating certain generation plants. Idaho Power
expects to spend a considerable amount on environmental compliance and controls in the next decade.
• Water Management and Relicensing of the Hells Canyon Hydroelectric Project: Because of Idaho Power's reliance
on stream flow in the Snake River and its tributaries, Idaho Power participates in numerous proceedings and venues
that may affect its water rights, seeking to preserve the long-term availability of its rights for its hydroelectric projects.
Also, Idaho Power is involved in renewing its long-term federal license for the HCC, its largest hydroelectric
generation source. Given the number of parties and issues involved, Idaho Power's relicensing costs have been and will
continue to be substantial. Idaho Power cannot currently determine the terms of, and costs associated with, any
resulting long-term license.

Sales Volume and Generation: In 2017, general business sales volumes increased 375 thousand MWh, or 3 percent, compared
with the prior year. Customer growth contributed to increased sales volumes in 2017 compared with 2016, with the number of
Idaho Power's customers growing by 2.0 percent in 2017 compared with 2016. In addition, cooling degree days in 2017 were
34 percent higher than 2016, which increased the use of electricity for cooling purposes. Heating degree days in 2017 were 18
percent higher than 2016, which increased the use of electricity for heating purposes. Increased commercial and industrial
activity in Idaho Power's service area led to an increase in sales volumes for commercial and industrial customers. These
increases in sales volumes were partially offset by a 9 percent decrease in sales volumes for irrigation customers in 2017
compared with 2016. Precipitation in the Idaho Power service area was significantly higher in 2017 compared with 2016, which
reduced usage by irrigation customers, particularly in the first six months of 2017.
Off-system sales volumes increased 950 thousand MWh, or 80 percent, during 2017 compared with 2016 due primarily to
increased hydroelectric generation exceeding the increased general business sales, resulting in more energy available for off-
system sales. During 2017, hydroelectric generation comprised 65 percent of Idaho Power's total system generation compared
with 53 percent during 2016. Generation from Idaho Power's hydroelectric plants increased due to significantly greater
precipitation in 2017 compared with 2016. Precipitation in Boise, Idaho was 77 percent higher in 2017 compared with 2016.
The financial impacts of fluctuations in off-system sales, purchased power, fuel expense, and other power supply-related
expenses are addressed in Idaho Power's Idaho and Oregon power cost adjustment mechanisms, which are described later in
this MD&A.

As part of its January 30, 2009 general rate case order, the IPUC is allowing Idaho Power to recover the allowance for funds used during construction
(AFUDC) on construction work in progress related to the HCC relicensing process, even though the relicensing process is not yet complete and the costs
have not been moved to electric plant in service. Idaho Power is collecting approximately $10.7 million annually in the Idaho jurisdiction for AFUDC on
HCC construction work in progress, but is deferring revenue recognition of the amounts collected until the license is issued and the accumulated license
costs are placed in service.
Changes in rates, changes in customer demand, and changes in FCA revenues are the primary causes for fluctuations in general
business revenue from period to period. See "Regulatory Matters" in this MD&A for a list of rate changes implemented over the
last three years. The primary influences on changes in customer demand for electricity are growth in number of customers,
weather, economic conditions, and energy efficiency. Rates are seasonally adjusted, providing for higher rates during the
summer peak load season, and residential customer rates are tiered, providing for higher rates based on higher levels of usage.
The seasonal and tiered rate structures contribute to seasonal fluctuations in revenues and earnings. Precipitation levels and the
timing of precipitation during the agricultural growing season also affect sales to customers who use electricity to operate
irrigation pumps. Extreme temperatures increase sales to customers who use electricity for cooling and heating, while moderate
temperatures decrease sales. For purposes of illustration, Boise, Idaho, weather-related information for the last three years is
presented in the following table.

(1) Heating and cooling degree-days are common measures used in the utility industry to analyze the demand for electricity and indicate when a customer would
use electricity for heating and air conditioning. A degree-day measures how much the average daily temperature varies from 65 degrees. Each degree of
temperature above 65 degrees is counted as one cooling degree-day, and each degree of temperature below 65 degrees is counted as one heating degree-day.
While Boise, Idaho weather conditions are not necessarily representative of weather conditions throughout Idaho Power's service area, the greater Boise area
has the majority of Idaho Power's customers.

General Business Revenues - 2017 Compared with 2016: General business revenue increased $60.0 million in 2017 compared
with 2016. The factors affecting general business revenues during the period are discussed below:
• Rates: Rate changes, including the revenue accruals provided for in the Valmy settlement stipulation, increased general
business revenue by $39.8 million for 2017 compared with 2016. In the second quarter of 2017, the IPUC and OPUC
each approved settlement stipulations related to Idaho Power’s plan to end its participation in coal-fired operations at
the Valmy Plant by the end of 2025, which increased general business revenue collections and general business
revenue accruals for 2017 compared with 2016. Colder winter temperatures in early 2017 and warmer summer
temperatures during the third quarter of 2017 resulted in residential sales making up a larger portion of the sales mix
and led to a greater proportion of residential sales in higher rate categories in Idaho Power's tiered rate structure in
2017 compared with 2016.
• Customers: Customer growth of 2.0 percent increased general business revenue by $12.1 million in 2017 compared
with 2016.
• Usage: Higher usage (on a per customer basis), primarily by residential, industrial, and commercial customers
increased general business revenue by $20.1 million in 2017 compared with 2016. Increased usage was primarily the
result of warmer summer temperatures and colder winter temperatures in Idaho Power's service area, which increased
usage by residential customers for cooling and heating. Cooling degree days and heating degree days were
significantly higher in 2017 compared with 2016. These increases in usage were partially offset by an 11 percent
decrease in usage per irrigation customer due to increased precipitation in Idaho Power's service area during 2017
compared with 2016, particularly in the first six months of 2017. Greater customer participation in energy efficiency
programs, resulting in decreased usage, partially offset the increase in total usage during 2017 compared with 2016.
•
Idaho FCA Revenue: The FCA mechanism adjusts revenue each year to collect, or refund, the difference between the
authorized fixed-cost recovery amount and the actual fixed costs recovered by Idaho Power during the year. Higher
usage (on a per customer basis) by residential and small general service customers during 2017 compared with 2016,
decreased the amount of FCA revenue accrued by $12.1 million for 2017 compared with 2016. Idaho Power accrued
$18.2 million of FCA revenue in 2017 compared with $30.3 million of FCA revenue in 2016.
General Business Revenues - 2016 Compared with 2015: General business revenue decreased $5.0 million in 2016 compared
with 2015. The factors affecting general business revenues during the period are discussed below:
• Rates: Rate changes decreased general business revenue by $3.9 million in 2016 compared with 2015, primarily due to
a decrease in the recovery of power cost adjustment amounts in 2016 compared with 2015. The recovery of power cost
adjustment amounts in rates has no effect on operating income as it is amortized into expense in the same period it is
recovered through rates.
• Customers: Customer growth of 1.8 percent increased general business revenue by $15.6 million in 2016 compared
with 2015.
• Usage: Lower usage (on a per customer basis), primarily by irrigation, commercial, and residential customers,
decreased general business revenue by $21.3 million in 2016 compared with 2015. Winter temperatures in 2016 were
slightly colder than 2015, but milder summer temperatures in 2016 compared with 2015 led to lower sales volumes. A
shorter irrigation season due to a later start in 2016 compared with 2015 resulted in lower usage per irrigation
customer in 2016 compared with 2015. Greater customer participation in energy efficiency programs also contributed
to lower usage during 2016 compared with 2015.
•
•
Sharing: Idaho Power's sharing mechanism is associated with an Idaho regulatory settlement agreement that provides
for the sharing with customers of a portion of Idaho-jurisdiction earnings exceeding a 10.0 percent Idaho ROE. The
impact of this mechanism is partially recorded as a reduction to general business revenue. During 2015, Idaho Power
recorded a total of $3.2 million as a provision against current revenue related to the sharing mechanism. In 2016, no
such sharing provision was recorded because Idaho Power's Idaho ROE did not exceed 10.0 percent.
Idaho FCA Revenue: Partially offsetting lower usage per customer, the Idaho FCA mechanism increased revenues by
$1.4 million in 2016 compared with 2015. Idaho Power accrued $30.3 million of Idaho FCA revenues in 2016,
compared with $28.9 million in 2015.

Off-System Sales: Off-system sales consist primarily of opportunity sales of surplus system energy. The table below presents

Off-System Sales - 2017 Compared with 2016: For 2017, off-system sales revenue increased by $8.2 million, or 32 percent
compared with 2016 as generation from Idaho Power's hydroelectric plants increased due to significantly greater precipitation
in 2017 compared with 2016. The increase in hydroelectric generation resulted in more energy available for off-system sales in
2017 compared with 2016. The average price of off-system sales was 26 percent lower for 2017 compared with 2016, as an
increase in output from hydroelectric resources in the northwest United States region due to increased precipitation during the
period, as well as additional output from new wind and solar projects throughout the region, increased surplus power available
for sale and decreased wholesale power market prices.
Off-System Sales - 2016 Compared with 2015: Off-system sales revenue decreased by $5.7 million, or 18 percent in 2016
compared with 2015. Off-system sales volumes decreased 5 percent in 2016 compared with 2015 as lower wholesale market
prices reduced the economic benefits of operating Idaho Power's non-hydroelectric generation facilities for off-system sales.
The average price of off-system sales in 2016 was 14 percent lower compared with 2015.

Other Revenues - 2017 Compared with 2016: Other revenues increased $17.4 million, or 20 percent, in 2017 compared with
2016. The increase was largely due to an increase in wheeling volumes, an increase in Idaho Power's OATT rates, and a new
long-term wheeling agreement that became effective in July 2016, all of which increased revenues in 2017 compared with
2016. Also, greater customer participation in energy efficiency programs increased other revenues and corresponding expenses
by $5.5 million in 2017 compared with 2016.
Most energy efficiency activities are funded through a rider mechanism on customer bills. Energy efficiency program
expenditures funded through the riders are reported as an operating expense with an equal amount of revenues recorded in other
revenues, resulting in no net impact on earnings. The cumulative variance between expenditures and amounts collected through
the rider is recorded as a regulatory asset or liability pending future collection from, or obligation to, customers. A liability
balance indicates that Idaho Power has collected more than it has spent and an asset balance indicates that Idaho Power has
spent more than it has collected. At December 31, 2017, Idaho Power's energy efficiency rider balances were a $0.4 million
regulatory liability in the Idaho jurisdiction and a $6.3 million regulatory asset in the Oregon jurisdiction. As described in Note
3 - "Regulatory Matters" to the consolidated financial statements in this report, the approved net increase in Idaho power cost
adjustment (PCA) rates, effective for the 2017-2018 PCA collection period from June 1, 2017, to May 31, 2018, included a
$13.0 million refund of previously collected Idaho energy efficiency rider funds.
Other Revenues - 2016 Compared with 2015: Other revenues increased $2.6 million, or 3 percent, in 2016 compared with 2015.
Greater customer participation in energy efficiency programs increased other revenues and corresponding expenses in 2016
compared with 2015. Most energy efficiency activities are funded through a rider mechanism on customer bills. Energy
efficiency program expenditures funded through the rider are reported as an operating expense with an equal amount of
revenues recorded in other revenues, resulting in no net impact on earnings. The cumulative variance between expenditures and
amounts collected through the rider is recorded as a regulatory asset or liability pending future collection from, or obligation to,
customers. A liability balance indicates that Idaho Power has collected more than it has spent and an asset balance indicates that
42
Idaho Power has spent more than it has collected. At December 31, 2016, Idaho Power's energy efficiency rider balances were a
$5.6 million regulatory asset in the Oregon jurisdiction and a $10.7 million regulatory liability in the Idaho jurisdiction.

Idaho Power is required by federal law to purchase power from some PURPA generation projects at a specified price regardless
of the then-current load demand or wholesale energy market prices. The intermittent, non-dispatchable nature of the PURPA
generation increases the likelihood that Idaho Power will at times be required to reduce output from its lower-cost hydroelectric
and fossil fuel-fired generation resources and may be required to sell its excess power in the wholesale power market at a
significant loss. The other purchased power cost per MWh often exceeds the off-system sales revenue per MWh because Idaho
Power generally needs to purchase more power during heavy load periods than during light load periods, and conversely has
less energy available for off-system sales during heavy load periods than light load periods. Market energy prices are typically
higher during heavy load periods than during light load periods. Also, in accordance with Idaho Power’s risk management
policy, Idaho Power may purchase or sell energy several months in advance of anticipated delivery. The regional energy market
price is dynamic and additional energy purchase or sale transactions that Idaho Power makes at current market prices may be
noticeably different than the advance purchase or sale transaction prices. Most of the non-PURPA purchased power and
substantially all of the PURPA power purchase costs are recovered through base rates and Idaho Power's power cost adjustment
mechanisms.
Purchased Power - 2017 Compared with 2016: Purchased power expense increased $3.2 million, or 1 percent, in 2017
compared with 2016, primarily due to an increase in generation provided by PURPA solar contracts. The increase in PURPA
volumes was partially offset by decreases in costs per MWh. Other purchased power expense decreased $12.9 million, or 15
percent, as abundant hydroelectric generation in 2017 compared with 2016 reduced the need for market purchases to meet load
requirements.
Purchased Power - 2016 Compared with 2015: Purchased power expense increased $19.3 million, or 9 percent, in 2016,
compared with 2015. The increase was due primarily to increased volumes purchased from both PURPA and non-PURPA
sources attributable largely to lower market prices at times that encouraged market purchases rather than operating some
generating units. Volume increases were partially offset by lower non-PURPA wholesale market prices.

2015 excludes 147 MWh of generation from the Jim Bridger power plant for which costs were capitalized during feasibility testing of capital projects under
contemplation.
(2)
Includes a negligible amount of expense and generation related to the Salmon diesel-fired generation plant.
The majority of the fuel for Idaho Power’s jointly-owned coal-fired plants is purchased through long-term contracts, including
purchases from BCC, a one-third owned joint venture of IERCo. The price of coal from BCC is subject to fluctuations in mine
operating expenses, geologic conditions, and production levels. BCC supplies up to two-thirds of the coal used by the Jim
Bridger plant. Natural gas is mainly purchased on the regional wholesale spot market at published index prices. In addition to
commodity (variable) costs, both natural gas and coal expense include costs that are more fixed in nature for items such as
capacity charges, transportation, and fuel handling. Period to period variances in fuel expense per MWh are noticeably
impacted by these fixed charges when generation output is substantially different between the periods.
Fuel Expense - 2017 Compared with 2016: Fuel expense decreased $33.7 million, or 19 percent, in 2017 compared with 2016,
due primarily to increased output from Idaho Power's hydroelectric plants, which reduced utilization of gas and coal generation.
Generation from the hydroelectric plants increased 39 percent during 2017 compared with 2016.
Fuel Expense - 2016 Compared with 2015: Fuel expense decreased $6.7 million, or 4 percent, in 2016 compared with 2015, due
primarily to decreased output from coal-fired plants and natural gas plants in 2016 compared with 2015. Overall generation
decreased 15 percent in 2016 compared with 2015 due to a change in resource mix resulting from increased purchase
requirements from cogeneration and small power production (CSPP) projects, resource constraints at various generating
locations, including the Langley Gulch natural gas-fired generation plant and the Jim Bridger coal-fired generating plant, due to
scheduled maintenance and other factors, and more open market purchases for economic reasons. The volume decreases were
partially offset by higher coal prices due to higher mining costs at BCC. The higher mining costs resulted in part due to issues
with underground mining equipment that is no longer in service.
Power Cost Adjustment Mechanisms: Idaho Power's power supply costs (primarily purchased power and fuel expense, less
off-system sales) can vary significantly from year to year. Volatility of power supply costs arises from factors such as weather
conditions, wholesale market prices, volumes of power purchased and sold in the wholesale markets, Idaho Power's
hydroelectric and thermal generation volumes and fuel costs, generation plant availability, and retail loads. To address the
volatility of power supply costs, Idaho Power's power cost adjustment mechanisms in the Idaho and Oregon jurisdictions allow
Idaho Power to recover from customers, or refund to customers, most of the fluctuations in power supply costs. In the Idaho
jurisdiction, the PCA includes a cost or benefit sharing ratio that allocates the deviations in net power supply expenses between
customers (95 percent) and Idaho Power (5 percent), with the exception of PURPA power purchases and demand response
program incentives, which are allocated 100 percent to customers. The Idaho deferral period, or PCA year, runs from April 1
through March 31. Amounts deferred during the PCA year are primarily recovered or refunded during the subsequent June 1
through May 31 period. Because of the power cost adjustment mechanisms, the primary financial impacts of power supply cost
variations is that cash is paid out but recovery from customers does not occur until a future period, or cash that is collected is
refunded to customers in a future period, resulting in fluctuations in operating cash flows from year to year.

The power supply accruals (deferrals) represent the portion of the power supply cost fluctuations accrued (deferred) under the
power cost adjustment mechanisms. When actual power supply costs are lower than the amount forecasted in power cost
adjustment rates, which was the case in 2017, most of the difference is accrued. When actual power supply costs are higher than
the amount forecasted in power cost adjustment rates, which was the case for 2016 and 2015, most of the difference is deferred.
The amortization of the prior year’s balances represents the offset to the amounts being collected or refunded in the current
power cost adjustment year that were deferred or accrued in the prior power cost adjustment year (the true-up component of the
power cost adjustment mechanism).
Power Cost Adjustment Mechanisms - 2017 Compared with 2016: Actual net power supply costs decreased in 2017 relative to
2016, resulting in a change of $58.5 million—from deferrals of $43.8 million to accruals of $14.7 million. The change from
deferrals in 2016 to accruals in 2017 is due in part to the lower fuel costs and purchased power, as explained above, combined
with more surplus sales than forecasted. The $37.4 million of amortization of prior year authorized balances offsets the
collection from customers of prior years' deferrals.
Power Cost Adjustment Mechanisms - 2016 Compared with 2015: Actual net power supply cost deferrals increased in 2016
relative to 2015, a change of $8.0 million—from $35.8 million to $43.8 million. The increase in the deferral is due in part to
higher fuel costs related to coal and purchased power and lower surplus sales than forecasted. The $38.5 million of amortization
offsets the collection from customers of 2015 deferrals and was lower in 2016 as Idaho Power amortized a smaller deferral
balance in 2016 than in 2015.
Other Operations and Maintenance Expenses: The changes in other O&M expenses for the periods presented are discussed
below.
O&M - 2017 Compared with 2016: Other O&M expense decreased by $2.2 million in 2017 compared with 2016, primarily due
to a $2.4 million decrease related to previously expensed energy efficiency rider-funded costs deemed to be prudently incurred
as further discussed in "Regulatory Matters" of this MD&A, and a $2.7 million decrease in thermal O&M expenses due to
lower generation at thermal plants. These decreases in O&M were partially offset by a $2.5 million increase in O&M related to
a settlement stipulation in Idaho, which established the reasonableness of the HCC relicensing costs incurred through December
2015 as further discussed in "Regulatory Matters" in this MD&A.
O&M - 2016 Compared with 2015: Other O&M expense increased by $9.7 million, or 3 percent, in 2016 compared with 2015
primarily due to a $6.5 million increase in labor-related expenses in 2016 due to normal increases in labor and benefits costs
and higher variable employee costs, a $1.6 million increase due to scheduled maintenance at the Langley Gulch natural gas-
fired generation plant, and a $1.1 million increase primarily related to transmission agreements entered into in October 2015,
which also resulted in a corresponding increase in other revenue.
Income Taxes
IDACORP's and Idaho Power's 2017 income tax expense increased $12.2 million and $14.1 million, respectively, when
compared with 2016. The increase was primarily due to higher pre-tax earnings at Idaho Power in 2017, and the $5.6 million
flow-through benefit of tax deductible make-whole premiums that Idaho Power paid in connection with the early redemption of
long-term debt in 2016. There were no early redemptions of long-term debt in 2017. These increases in income tax expense
were partially offset by greater net flow-through income tax items at Idaho Power.
IDACORP's and Idaho Power's 2016 income tax expense decreased $9.3 million and $11.0 million, respectively, when
compared with 2015. The decrease was primarily due to greater net flow-through income tax benefits at Idaho Power, a tax
benefit from the adoption of a new accounting standard for share-based compensation, distributions related to fully-amortized
affordable housing investments at IDACORP, and lower Idaho Power pre-tax earnings in 2016.
45
On December 22, 2017, the Tax Cuts and Jobs Act was signed into law, which significantly reforms the Internal Revenue Code
of 1986, as amended. Effective January 1, 2018, the Tax Cuts and Jobs Act permanently lowers the corporate tax rate to 21
percent from the existing maximum rate of 35 percent, provides for expanded bonus depreciation, limits the deductibility of
interest expense, eliminates alternative minimum tax, repeals the manufacturing deduction, and imposes additional limitations
on the deductibility of executive compensation. Public utility companies, such as Idaho Power, retain the full deductibility of
interest expense and are excluded from the bonus depreciation provisions; however, traditional accelerated tax depreciation
methods are still available.
As a result of the reduction of the corporate tax rate to 21 percent, generally accepted accounting principles require companies
to remeasure their deferred tax assets and liabilities as of the date of enactment, with resulting tax effects accounted for in the
reporting period of enactment. This remeasurement resulted in a $1.7 million and $2.0 million increase in income tax expense at
IDACORP and Idaho Power, respectively, and an approximate $672 million reduction to net deferred tax liabilities of both
companies. For additional information relating to IDACORP's and Idaho Power's income taxes, the effects of the Tax Cuts and
Jobs Act, and the availability of tax credit carryforwards, see Note 2 - “Income Taxes” to the consolidated financial statements
included in this report.
LIQUIDITY AND CAPITAL RESOURCES
Overview
Idaho Power continues to pursue significant enhancements to its utility infrastructure in an effort to ensure an adequate supply
of electricity, to provide service to new customers, and to maintain system reliability. Idaho Power's existing hydroelectric and
thermal generation facilities also require continuing upgrades and component replacement. Idaho Power's expenditures for
property, plant, and equipment, excluding AFUDC, were $277 million in 2017, $287 million in 2016, and $284 million in 2015.
Idaho Power expects these substantial capital expenditures to continue, with estimated total capital expenditures of
approximately $1.5 billion expected over the period from 2018 through 2022.
Idaho Power funds its liquidity needs for capital expenditures through cash flows from operations, debt offerings, commercial
paper markets, credit facilities, and capital contributions from IDACORP. As of February 16, 2018, IDACORP's and Idaho
Power's access to debt, equity, and credit arrangements included:
•
•
•
•
their respective $100 million and $300 million revolving credit facilities;
IDACORP's shelf registration statement filed with the SEC on May 20, 2016, which may be used for the issuance of
debt securities and common stock;
Idaho Power's shelf registration statement filed with the SEC on May 20, 2016, which may be used for the issuance of
first mortgage bonds and debt securities; $500 million is available for issuance pursuant to state regulatory authority;
and
IDACORP's and Idaho Power's issuance of commercial paper, which may be issued up to an amount equal to the
available credit capacity under their respective credit facilities.
Based on planned capital expenditures and operating and maintenance expenses for 2018, the companies believe they will be
able to meet capital requirements and fund corporate expenses during 2018 with a combination of existing cash and operating
cash flows generated by Idaho Power's utility business, together with proceeds from either draws on credit facilities or Idaho
Power's issuance of debt securities. IDACORP and Idaho Power believe they could meet any short-term cash shortfall with
existing credit facilities and expect to continue to manage short-term liquidity through commercial paper markets.
IDACORP and Idaho Power monitor capital markets with a view toward opportunistic debt and equity transactions, taking into
account current and potential future long-term needs. As a result, IDACORP may issue debt securities or common stock, and
Idaho Power may issue debt securities, if the companies believe terms available in the capital markets are favorable and that
issuances would be financially prudent. Idaho Power also periodically analyzes whether partial or full early redemption of one
or more existing outstanding series of first mortgage bonds is desirable, and in some cases may refinance indebtedness with
new indebtedness issued with more favorable terms. To that end, on March 10, 2016, Idaho Power issued $120 million in
principal amount of 4.05% first mortgage bonds, Series J, maturing on March 1, 2046. On April 11, 2016, Idaho Power
redeemed, prior to maturity, its $100 million in principal amount of 6.15% first mortgage bonds, Series H, due April 2019. In
accordance with the redemption provisions of the original terms of the notes, the redemption included payment by Idaho Power
of a make-whole premium of $14 million. The make-whole premium resulted in a current income tax deduction, which under
Idaho Power's regulatory flow-through tax accounting produced an income tax benefit of approximately $5.6 million recorded
46
in the second quarter of 2016. Idaho Power also expects to receive an incremental net benefit to net income as a result of the
lower interest rate of the notes issued in March 2016 compared with the interest rate associated with the redeemed notes. Idaho
Power used a portion of the net proceeds of the March 2016 sale of first mortgage bonds, medium-term notes to effect the
redemption.
IDACORP and Idaho Power seek to maintain capital structures of approximately 50 percent debt and 50 percent equity, and
maintaining this ratio influences IDACORP's and Idaho Power's debt and equity issuance decisions. As of December 31, 2017,
IDACORP's and Idaho Power's capital structures, as calculated for purposes of applicable debt covenants, were as follows:
IDACORP
Idaho Power
Debt
Equity
44%
56%
46%
54%
IDACORP and Idaho Power generally maintain their cash and cash equivalents in highly liquid investments, such as U.S.
Treasury Bills, money market funds, and bank deposits.
Operating Cash Flows
IDACORP's and Idaho Power's principal sources of cash flows from operations are Idaho Power's sales of electricity and
transmission capacity. Significant uses of cash flows from operations include the purchase of fuel and power, other operating
expenses, interest, income taxes, and pension plan contributions. Operating cash flows can be significantly influenced by
factors such as weather conditions, rates and the outcome of regulatory proceedings, and economic conditions. As fuel and
purchased power are significant uses of cash, Idaho Power has regulatory mechanisms in place that provide for the deferral and
recovery of the majority of the fluctuation in those costs. However, if actual costs rise above the level allowed in retail rates,
deferral balances increase (reflected as a regulatory asset), negatively affecting operating cash flows until such time as those
costs, with interest, are recovered from customers.
IDACORP’s and Idaho Power’s operating cash inflows in 2017 were $438 million and $420 million, respectively, an increase
of $90 million for IDACORP and a $109 million increase for Idaho Power when compared with 2016. Significant items that
affected the companies' operating cash flows in 2017 relative to 2016 were as follows:
•
•
•
•
a $15 million increase and $17 million increase in IDACORP and Idaho Power net income, respectively, which includes a
$19 million increase in non-cash depreciation and amortization at both companies;
changes in regulatory assets and liabilities, mostly related to the relative amounts of power supply and fixed costs deferred
and collected under the Idaho rate mechanisms, increased operating cash inflows by $63 million. The increase is mostly
related to the relative amounts of power supply and fixed costs deferred and collected under the Idaho power cost
adjustment and FCA mechanisms, partially offset by revenues accrued in excess of collections from the Valmy Plant
settlement stipulation that will be collected in future periods;
changes in deferred taxes and in taxes accrued and receivable combined to increase cash flows by $1 million and decrease
cash flows by $23 million at IDACORP and Idaho Power, respectively;
changes in working capital balances due primarily to timing, including fluctuations in accounts receivable, other current
assets, accounts payable, and other current liabilities, as follows:
timing of collections of accounts receivable balances increased operating cash flows by $7 million for IDACORP
and decreased operating cash flows by $6 million for Idaho Power. IDACORP collected a $8 million receivable in
the first quarter of 2017 from a legal settlement;
the changes in other current assets increased cash flows by $14 million, which was primarily due to fluctuations in
the balance in accrued unbilled revenues as energy sales near the end of the respective periods were impacted by
weather; and
timing of accounts payable payments decreased operating cash flows by $31 million for IDACORP and increased
operating cash flows by $25 million for Idaho Power (the difference relates to a $55 million payable from Idaho
Power to IDACORP relating to estimated income tax payments).
IDACORP's and Idaho Power's operating cash inflows in 2016 were $348 million and $311 million, respectively, a decrease of
$5 million for IDACORP and $35 million decrease for Idaho Power when compared with 2015. Significant items that affected
the companies' operating cash flows in 2016 relative to 2015 were as follows:
47
•
•
•
•
changes in regulatory assets and liabilities, mostly related to the relative amounts of power supply and fixed costs
deferred and collected under the Idaho rate mechanisms, decreased operating cash inflows by $19 million;
changes in deferred taxes and in taxes accrued and receivable combined to decrease cash flows by $3 million and $34
million at IDACORP and Idaho Power, respectively;
Idaho Power received $24 million of distributions from IERCo's investment in BCC for 2016, compared with $11
million in 2015. Changes in distributions from year to year are primarily driven by changes in the timing of cash needs
associated with BCC; and
comparative changes in working capital and other assets and liabilities increased cash flows by $7 million in 2016
compared with 2015, primarily related to changes in accounts payable due to timing of payments.
Investing Cash Flows
Investing activities consist primarily of capital expenditures related to new construction and improvements to Idaho Power’s
generation, transmission, and distribution facilities. Idaho Power's construction expenditures, including the allowance for
borrowed funds used during construction, were $285 million, $297 million, and $294 million in 2017, 2016, and 2015,
respectively. These capital expenditures were primarily for construction of utility infrastructure needed to address Idaho
Power’s aging plant and equipment, customer growth, and environmental and regulatory compliance requirements. As
discussed in "Capital Requirements" below, Idaho Power received $6 million and $8 million in 2017 and 2016 from Boardman-
to-Hemingway project joint permitting participants relating to a portion of these construction expenditures.
Idaho Power has a Rabbi trust designated to provide funding for obligations of its nonqualified defined benefit plans. In the
Rabbi trust, Idaho Power purchased $11 million, $15 million, and $14 million of available-for-sale securities in 2017, 2016, and
2015, respectively. In 2017, 2016, and 2015, Idaho Power received $5 million, $16 million and $34 million, respectively, of
proceeds from the sales of available-for-sale securities. Idaho Power did not use any of these proceeds to acquire company-
owned life insurance in 2017, but used $10 million and $30 million of the proceeds to acquire company-owned life insurance in
2016 and 2015, respectively.
Financing Cash Flows
Financing activities provide supplemental cash for both day-to-day operations and capital requirements as needed. Idaho Power
funds liquidity needs for capital investment, working capital, managing commodity price risk, and other financial commitments
through cash flows from operations, debt offerings, commercial paper markets, credit facilities, and capital contributions from
IDACORP. IDACORP funds its cash requirements, such as payment of taxes, capital contributions to Idaho Power, and non-
utility operating expenses through cash flows from operations, commercial paper markets, sales of common stock, and credit
facilities. The following are significant items and transactions that affected financing cash flows in 2017, 2016, and 2015:
•
•
•
•
•
•
•
on March 10, 2016, Idaho Power issued $120 million in principal amount of 4.05% first mortgage bonds Series J,
maturing March 1, 2046;
on April 11, 2016, Idaho Power redeemed, prior to maturity, $100 million of its 6.15% first mortgage bonds, Series H,
due April 1, 2019, and paid a related make-whole premium of $14 million;
on March 6, 2015, Idaho Power issued $250 million in principal amount of 3.65% first mortgage bonds, Series J,
maturing on March 1, 2045;
on April 23, 2015, Idaho Power redeemed, prior to maturity, $120 million in principal amount of 6.025% first
mortgage bonds, medium-term notes due July 2018, and paid a related make-whole premium of $18 million;
IDACORP and Idaho Power paid dividends of approximately $113 million, $105 million, and $97 million in 2017,
2016, and 2015, respectively;
IDACORP's net change in commercial paper borrowings used cash of $22 million in 2017 and provided cash of $2
million and used cash of $11 million in 2016 and 2015, respectively; and
Idaho Power borrowed $22 million in commercial paper in December 2016, which was paid off in January of 2017.
Financing Programs and Available Liquidity
IDACORP Equity Programs: In recent years IDACORP has entered into sales agency agreements under which IDACORP
could offer and sell shares of its common stock from time to time through BNY Mellon Capital Markets, LLC as IDACORP's
agent. The most recent agency agreement terminated in May 2016, but IDACORP may choose to enter into a new sales agency
agreement in the future. On May 20, 2016, IDACORP filed a shelf registration statement with the SEC, which became effective
upon filing, for the potential offer and sale of an unspecified amount of shares of common stock. As of the date of this report,
IDACORP is assessing whether to execute a new sales agency agreement for the issuance and sale of common stock, as the
48
company does not anticipate issuing any shares of its common stock outside of its equity or deferral compensation programs in
2018.
Since 2012, IDACORP has not used original issue shares of common stock for the IDACORP, Inc. Dividend Reinvestment and
Stock Purchase Plan or the Idaho Power Company Employee Savings Plan, but instead plan administrators have used market
purchases of IDACORP common stock. However, IDACORP may determine at any time to use original issuances of common
stock under those plans. As noted above, an important component of that determination will be IDACORP's and Idaho Power's
capital structure.
Idaho Power First Mortgage Bonds: Idaho Power's issuance of long-term indebtedness is subject to the approval of the IPUC,
OPUC, and Wyoming Public Service Commission (WPSC). In April and May 2016, Idaho Power received orders from the
IPUC, OPUC, and WPSC authorizing Idaho Power to issue and sell from time to time up to $500 million in aggregate principal
amount of debt securities and first mortgage bonds, subject to conditions specified in the orders. Authority from the IPUC is
effective through May 31, 2019, subject to extension upon request to the IPUC. The OPUC's and WPSC's orders do not impose
a time limitation for issuances, but the OPUC order does impose a number of other conditions, including a requirement that the
interest rates for the debt securities or first mortgage bonds fall within either (a) designated spreads over comparable U.S.
Treasury rates or (b) a maximum interest rate limit of seven percent.
On September 27, 2016, Idaho Power entered into a selling agency agreement with seven banks named in the agreement in
connection with the potential issuance and sale from time to time of up to $500 million in aggregate principal amount of first
mortgage bonds, secured medium term notes, Series K (Series K Notes), under Idaho Power’s Indenture of Mortgage and Deed
of Trust, dated as of October 1, 1937, as amended and supplemented (Indenture). At the same time, Idaho Power entered into
the Forty-eighth Supplemental Indenture, dated as of September 1, 2016, to the Indenture (Forty-eighth Supplemental
Indenture). The Forty-eighth Supplemental Indenture provides for, among other items, (a) the issuance of up to $500 million in
aggregate principal amount of Series K Notes pursuant to the Indenture and (b) the increase of the maximum amount of
obligations to be secured by the Indenture to $2.5 billion (which maximum amount may be further increased or decreased by
Idaho Power without the consent of the holders of first mortgage bonds). As of the date of this report, Idaho Power had not sold
any first mortgage bonds, including Series K Notes, or debt securities under the selling agency agreement.
The issuance of first mortgage bonds requires that Idaho Power meet interest coverage and security provisions set forth in the
Indenture. Future issuances of first mortgage bonds are subject to satisfaction of covenants and security provisions set forth in
the Indenture, market conditions, regulatory authorizations, and covenants contained in other financing agreements.
The Indenture limits the amount of first mortgage bonds at any one time outstanding to $2.5 billion, and as a result the
maximum amount of first mortgage bonds Idaho Power could issue as of December 31, 2017, was limited to approximately
$759 million. Idaho Power may increase the $2.5 billion limit on the maximum amount of first mortgage bonds outstanding by
filing a supplemental indenture with the trustee as provided in the Indenture of Mortgage and Deed of Trust. Separately, the
Indenture also limits the amount of additional first mortgage bonds that Idaho Power may issue to the sum of (a) the principal
amount of retired first mortgage bonds and (b) 60 percent of total unfunded property additions, as defined in the Indenture. As
of December 31, 2017, Idaho Power could issue approximately $1.8 billion of additional first mortgage bonds based on retired
first mortgage bonds and total unfunded property additions.
Refer to Note 4 - “Long-Term Debt” to the consolidated financial statements included in this report for more information
regarding long-term financing arrangements.
IDACORP and Idaho Power Credit Facilities: In November 2015, IDACORP and Idaho Power entered into credit agreements
for $100 million and $300 million credit facilities, respectively. These facilities replaced IDACORP's and Idaho Power's
existing Second Amended and Restated Credit Agreements, dated October 26, 2011, as amended. Each of the credit facilities
may be used for general corporate purposes and commercial paper back-up. IDACORP's facility permits borrowings under a
revolving line of credit of up to $100 million at any one time outstanding, including swingline loans not to exceed $10 million
at any time and letters of credit not to exceed $50 million at any time. IDACORP's facility may be increased, subject to
specified conditions, to $150 million. Idaho Power's facility permits borrowings through the issuance of loans and standby
letters of credit of up to $300 million at any one time outstanding, including swingline loans not to exceed $30 million at any
one time and letters of credit not to exceed $100 million at any time. Idaho Power's facility may be increased, subject to
specified conditions, to $450 million. The interest rates for any borrowings under the facilities are based on either (1) a floating
rate that is equal to the highest of the prime rate, federal funds rate plus 0.5 percent, or LIBOR rate plus 1.0 percent, or (2) the
LIBOR rate, plus, in each case, an applicable margin, provided that the federal funds rate and LIBOR rate will not be less than
zero percent. The applicable margin is based on IDACORP's or Idaho Power's, as applicable, senior unsecured long-term
49
indebtedness credit rating, as set forth on a schedule to the credit agreements. The companies also pay a facility fee based on the
respective company's credit rating for senior unsecured long-term debt securities.
Each facility contains a covenant requiring each company to maintain a leverage ratio of consolidated indebtedness to
consolidated total capitalization equal to or less than 65 percent as of the end of each fiscal quarter. In determining the leverage
ratio, “consolidated indebtedness” broadly includes all indebtedness of the respective borrower and its subsidiaries, including,
in some instances, indebtedness evidenced by certain hybrid securities (as defined in the credit agreement). “Consolidated total
capitalization” is calculated as the sum of all consolidated indebtedness, consolidated stockholders' equity of the borrower and
its subsidiaries, and the aggregate value of outstanding hybrid securities. At December 31, 2017, the leverage ratios for
IDACORP and Idaho Power were 44 percent and 46 percent, respectively. IDACORP's and Idaho Power's ability to utilize the
credit facilities is conditioned upon their continued compliance with the leverage ratio covenants included in the credit
facilities. There are additional covenants, subject to exceptions, that prohibit certain mergers, acquisitions, and investments,
restrict the creation of certain liens, and prohibit entering into any agreements restricting dividend payments from any material
subsidiary. At December 31, 2017, IDACORP and Idaho Power believe they were in compliance with all facility covenants.
Further, IDACORP and Idaho Power do not believe they will be in violation or breach of their respective debt covenants during
2018.
The events of default under both facilities include, without limitation, non-payment of principal, interest, or fees; materially
false representations or warranties; breach of covenants; bankruptcy or insolvency events; condemnation of property; cross-
default to certain other indebtedness; failure to pay certain judgments; change of control; failure of IDACORP to own free and
clear of liens the voting stock of Idaho Power; the occurrence of specified events or the incurring of specified liabilities relating
to benefit plans; and the incurring of certain environmental liabilities, subject, in certain instances, to cure periods.
Upon any event of default relating to the voluntary or involuntary bankruptcy of IDACORP or Idaho Power or the appointment
of a receiver, the obligations of the lenders to make loans under the applicable facility and to issue letters of credit will
automatically terminate and all unpaid obligations will become due and payable. Upon any other event of default, the lenders
holding greater than 50 percent of the outstanding loans or greater than 50 percent of the aggregate commitments (required
lenders) or the administrative agent with the consent of the required lenders may terminate or suspend the obligations of the
lenders to make loans under the facility and to issue letters of credit under the facility and/or declare the obligations to be due
and payable. During an event of default under the facilities, the lenders may, at their option, increase the applicable interest
rates then in effect and the letter of credit fee by 2.0 percentage points per annum. A ratings downgrade would result in an
increase in the cost of borrowing, but would not result in a default or acceleration of the debt under the facilities. However, if
Idaho Power's ratings are downgraded below investment grade, Idaho Power must extend or renew its authority for borrowings
under its IPUC and OPUC regulatory orders.
While the credit facilities provide for an original maturity date of November 6, 2020, the credit agreements grant IDACORP
and Idaho Power the right to request up to two one-year extensions, in each case subject to certain conditions. On November 7,
2016, IDACORP and Idaho Power executed the first extension agreement and on November 7, 2017, executed the second
extension agreement with the consent of all the lenders, extending the maturity date under both credit agreements to November
4, 2022. No other terms of the credit facilities, including the amount of permitted borrowing under the credit agreements, were
affected by the extensions.
Without additional approval from the IPUC, the OPUC, and the WPSC, the aggregate amount of short-term borrowings by
Idaho Power at any one time outstanding may not exceed $450 million. Idaho Power has obtained approval of the state public
utility commissions of Idaho, Oregon, and Wyoming for the issuance of short-term borrowings through November 2022.
IDACORP and Idaho Power Commercial Paper: IDACORP and Idaho Power have commercial paper programs under which
they issue unsecured commercial paper notes up to a maximum aggregate amount outstanding at any time not to exceed the
available capacity under their respective credit facilities, described above. IDACORP's and Idaho Power's credit facilities are
available to the companies to support borrowings under their commercial paper programs. The commercial paper issuances are
used to provide an additional financing source for the companies' short-term liquidity needs. The maturities of the commercial
paper issuances will vary, but may not exceed 270 days from the date of issue. Individual instruments carry a fixed rate during
their respective terms, although the interest rates are reflective of current market conditions, subjecting the companies to
fluctuations in interest rates.

Impact of Credit Ratings on Liquidity and Collateral Obligations
IDACORP’s and Idaho Power’s access to capital markets, including the commercial paper market, and their respective
financing costs in those markets, depends in part on their respective credit ratings. The following table outlines the ratings of
Idaho Power’s and IDACORP’s securities, and the ratings outlook, by Moody’s Investors Service and Standard & Poor’s
Ratings Services as of the date of this report:

These security ratings reflect the views of the ratings agencies. An explanation of the significance of these ratings may be
obtained from each rating agency. Such ratings are not a recommendation to buy, sell, or hold securities. Any rating can be
revised upward or downward or withdrawn at any time by a rating agency if it decides that the circumstances warrant the
51
change. Each rating agency has its own methodology for assigning ratings and, accordingly, each rating should be evaluated
independently of any other rating.
Idaho Power maintains margin agreements relating to its wholesale commodity contracts that allow performance assurance
collateral to be requested of and/or posted with certain counterparties. As of December 31, 2017, Idaho Power had posted $0.9
million performance assurance collateral. Should Idaho Power experience a reduction in its credit rating on its unsecured debt
to below investment grade, Idaho Power could be subject to requests by its wholesale counterparties to post additional
performance assurance collateral, and counterparties to derivative instruments and other forward contracts could request
immediate payment or demand immediate ongoing full daily collateralization on derivative instruments and contracts in net
liability positions. Based upon Idaho Power’s current energy and fuel portfolio and market conditions as of December 31, 2017,
the amount of additional collateral that could be requested upon a downgrade to below investment grade is approximately $5.0
million. To minimize capital requirements, Idaho Power actively monitors its portfolio exposure and the potential exposure to
additional requests for performance assurance collateral through sensitivity analysis.
Capital Requirements
Idaho Power's construction expenditures, excluding AFUDC, were $277 million during the year ended December 31, 2017. The
table below presents Idaho Power's estimated cash requirements for construction, excluding AFUDC, for 2018 through 2022 (in
millions of dollars). However, given the uncertainty associated with the timing of infrastructure projects and associated
expenditures, actual expenditures and their timing could deviate substantially from those set forth in the table.

Infrastructure Projects: A significant portion of expected capital expenditures included in the five-year forecast above relate to
a large number of small projects as Idaho Power continues to add to its system to accommodate growth and improve reliability
and operational effectiveness. These projects involve significant capital expenditures. Examples of anticipated system
enhancements planned for 2018 through 2022 and estimated costs include the following:
•
•
•
•
•
$35-$65 million per year for transmission system projects other than the Boardman-to-Hemingway and Gateway West
projects;
$85-$105 million per year for construction and replacement of distribution lines and stations, including replacement of
underground distribution cables;
$20-$40 million per year for ongoing improvements and replacements at coal- and natural gas-fired plants;
$40-$65 million per year for hydroelectric plant improvement programs, including relicensing costs; and
$45-$75 million per year for general plant improvements, such as land and buildings, vehicles, information
technology, and communication equipment.
Other Major Infrastructure Projects: Idaho Power has recently completed or is engaged in the development of a number of
significant projects and has entered into arrangements with third parties for joint development of infrastructure projects. The
most notable projects are described below.
Jim Bridger Plant Selective Catalytic Reduction Equipment: Idaho Power and the plant co-owners recently completed
installation of selective catalytic reduction (SCR) equipment to reduce nitrogen oxide (NOx) emissions at the Jim Bridger power
plant, in order to comply with regional haze rules. The regional haze rules provided for installation of SCR on unit 3 and unit 4.
The rules provide for an equivalent technology for NOx reductions on unit 2 by 2021 and unit 1 by 2022.The unit 3 SCR was
operating as of November 2015, and the unit 4 SCR was operating as of November 2016. In light of the substantial estimated
cost of the SCR installation, as of the date of this report, Idaho Power is assessing whether to move forward with the installation
of SCR on units 1 and 2 at the Jim Bridger power plant. The expected capital expenditures in the table above do not include any
estimated expenditures relating to the installation of SCR on units 1 and 2.
Boardman-to-Hemingway Transmission Line: The Boardman-to-Hemingway line, a proposed 300-mile, 500-kV transmission
project between a station near Boardman, Oregon, and the Hemingway station near Boise, Idaho, would provide transmission
service to meet future resource needs. In January 2012, Idaho Power entered into a joint funding agreement with PacifiCorp and
the Bonneville Power Administration to pursue permitting of the project. The joint funding agreement provides that Idaho
Power's interest in the permitting phase of the project would be approximately 21 percent, and that during future negotiations
relating to construction of the transmission line Idaho Power would seek to retain that percentage interest in the completed
project. Total cost estimates for the project are between $1.0 billion and $1.2 billion, including Idaho Power's AFUDC. This
52
cost estimate is preliminary and excludes the impacts of inflation and price changes of materials and labor resources that may
occur following the date of the estimate. Idaho Power's share of the permitting phase of the project (excluding AFUDC) is
included in the capital requirements table above in addition to approximately $50 million of Idaho Power's share of costs
related to early construction efforts primarily included in the periods 2020-2022. These preliminary estimates of Idaho Power’s
share of early construction costs could significantly change as the construction timeline nears and as the project participants
further align on future activities and estimates.
Approximately $95 million, including AFUDC, has been expended on the Boardman-to-Hemingway project through
December 31, 2017. Pursuant to the terms of the joint funding arrangements, Idaho Power has received $68 million, including
$19 million received in January 2018, due from project partners for their share of those costs. As of the date of this report, no
material partner reimbursements are outstanding. Joint permitting participants are obligated to reimburse Idaho Power for their
share of any future project permitting expenditures incurred by Idaho Power.
The permitting phase of the Boardman-to-Hemingway project is subject to federal review and approval by the U.S. Bureau of
Land Management (BLM), the U.S. Forest Service, the Department of the Navy, and certain other federal agencies. The BLM
issued its record of decision for the project in November 2017. The U.S. Forest Service and Department of Navy are expected
to issue their respective decisions in 2018.
In the separate Oregon state permitting process, in June 2017, Idaho Power submitted its amended preliminary application for
site certificate and expects the Oregon Department of Energy to issue a draft proposed order on the application in 2018. Given
the status of ongoing permitting activities and construction period, Idaho Power expects the in-service date for the line would
be in 2025 or beyond.
Gateway West Transmission Line: Idaho Power and PacifiCorp are pursuing the joint development of the Gateway West
project, a 500-kV transmission project between a station located near Douglas, Wyoming and the Hemingway station. In
January 2012, Idaho Power and PacifiCorp entered a joint funding agreement for permitting of the project. Idaho Power's
estimated cost for the permitting phase of the Gateway West project is approximately $60 million, including AFUDC. Idaho
Power has expended approximately $35 million on the permitting phase of the project through December 31, 2017. As of the
date of this report, Idaho Power estimates the total cost for its share of the project (including both permitting and construction)
to be between $200 million and $400 million, including AFUDC. Idaho Power's share of the permitting phase of the project
(excluding AFUDC) is included in the capital requirements table above. Idaho Power's share of potential early construction
costs are excluded from the capital requirements table above because the timing of construction of Idaho Power's portion of the
project is uncertain.
The permitting phase of the Gateway West project is subject to review and approval of the BLM. The BLM released its record
of decision in November 2013 for eight of the ten transmission line segments. In May 2017, a federal bill was signed into law
that issued a right-of-way for certain portions of the remaining Gateway West segments. The other portions of the remaining
segments continue to be subject to the BLM's review and approval. Idaho Power expects the BLM to issue a record of decision
for the outstanding portions of the remaining segments in 2018.
Hells Canyon Complex Relicensing: The HCC, located on the Snake River where it forms the border between Idaho and
Oregon, provides approximately 68 percent of Idaho Power's hydroelectric generating nameplate capacity and 32 percent of its
total generating nameplate capacity. Idaho Power has been engaged in the process of obtaining from the FERC a new long-term
license for the HCC. The past and anticipated future costs associated with obtaining a new long-term license for the HCC are
significant. As of the date of this report, Idaho Power estimates that the annual costs it will incur to obtain a new long-term
license for the HCC, including AFUDC but excluding costs expected to be incurred for complying with the license after
issuance, are likely to range from $25 million to $35 million until issuance of the license, which Idaho Power estimates will
occur no earlier than 2022. Idaho Power expects that the annual capital expenditures and operating and maintenance expenses
associated with compliance with the terms and conditions of the long-term license could also be substantial, but the company is
currently unable to estimate those costs in light of the uncertainty surrounding the ultimate terms and conditions that may be
included in the license. Idaho Power intends to seek recovery of those relicensing and compliance costs in rates through the
regulatory process. In December 2016, Idaho Power filed an application with the IPUC requesting a determination that Idaho
Power's expenditures of $220.8 million through year-end 2015 on relicensing of the HCC were prudently incurred, and thus
eligible for inclusion in retail rates in a future rate proceeding. In December 2017, Idaho Power filed with the IPUC a settlement
stipulation signed by Idaho Power, the IPUC staff, and a third party intervenor recognizing that a total of $216.5 million in
HCC relicensing expenditures and other related costs were reasonably incurred, and therefore should be eligible for inclusion in
customer rates at a later date. The settlement stipulation is subject to review and approval by the IPUC. As a result of filing the
settlement stipulation, Idaho Power recorded a $5.0 million pre-tax charge in 2017. As of the date of this report, the IPUC has
53
not issued an order in this matter. Refer to "Regulatory Matters" in this MD&A for additional details relating to the relicensing
process.
Environmental Regulation Costs: Idaho Power anticipates that it will incur significant expenditures for the installation of
environmental controls at its coal-fired plants and for its hydroelectric relicensing efforts. The near-term cost estimates for
environmental matters are summarized in Part I, Item 1 - "Business" of this report. The capital portion of these amounts is
included in the Capital Requirements table above but does not include costs related to possible changes in current or new
environmental laws or regulations and enforcement policies that may be enacted in response to issues such as climate change
and emissions from coal-fired and gas-fired generation plants.
Long-Term Resource Planning: The IPUC and OPUC require that Idaho Power prepare biennially an IRP. The IRP seeks to
forecast Idaho Power's loads and resources for a 20-year period, analyzes potential supply-side, demand-side, and transmission
options, and identifies potential near-term and long-term actions. Idaho Power filed its most recent IRP with the IPUC and
OPUC in June 2017. The 2017 IRP identified a preferred resource portfolio and action plan, which includes the completion of
the Boardman-to-Hemingway transmission line by 2026, the end to Idaho Power's participation in coal-fired operations at the
Valmy Plant units 1 and 2 in 2019 and 2025, respectively, and the early retirement of Jim Bridger units 1 and 2 in 2032 and
2028, respectively, with no other new resource needs prior to 2026. However, as noted in the 2017 IRP, there is considerable
uncertainty surrounding the resource sufficiency estimates and project completion dates, including uncertainty around the
timing and extent of third party development of renewable resources, fuel commodity prices, environmental requirements, the
actual completion date of the Boardman-to-Hemingway transmission project, and the economics and logistics of plant operation
and retirements. These uncertainties, as well as others, could result in changes to the desirability of the preferred portfolio and
adjustments to the timing and nature of anticipated and actual actions. Additional information on Idaho Power's 2017 IRP is
included in Part I, Item 1 - "Business - Resource Planning" in this report.
Defined Benefit Pension Plan Contributions and Recovery
Idaho Power contributed $40 million in both 2017 and 2016 to its defined benefit pension plan and $39 million in 2015. Idaho
Power estimates that it has no minimum contribution requirement for 2018. Depending on market conditions and cash flow
considerations in 2018, Idaho Power could contribute up to $40 million to the pension plan during 2018. Idaho Power's
contributions are made in a continued effort to balance the regulatory collection of these expenditures with the amount and
timing of contributions to mitigate the cost of being in an underfunded position. Beyond 2018, Idaho Power expects continuing
significant contribution obligations under the pension plan. Refer to Note 10 - "Benefit Plans" to the consolidated financial
statements included in this report and the section titled "Contractual Obligations" below in this MD&A for information relating
to those obligations.
Idaho Power defers its Idaho-jurisdiction pension expense as a regulatory asset until recovered from Idaho customers. As of
December 31, 2017, Idaho Power's deferral balance associated with the Idaho jurisdiction was $128 million. Deferred pension
costs are expected to be amortized to expense to match the revenues received when contributions are recovered through rates.
Idaho Power only records a carrying charge on the unrecovered balance of cash contributions. The IPUC has authorized Idaho
Power to recover and amortize $17 million of deferred pension costs annually, and has applied $68 million against the deferred
amount under its Idaho sharing mechanisms since 2011. The primary impact of pension contributions is on the timing of cash
flows, as cost recovery lags behind the timing of contributions.
Tax Cuts and Jobs Act
On December 22, 2017, the Tax Cuts and Jobs Act was signed into law, which lowered the corporate federal income tax rate
from 35 percent to 21 percent and modified or eliminated certain federal income tax deductions for corporations. The majority
of the law changes, including the rate reduction, became effective on January 1, 2018. Idaho Power is working with the IPUC
and OPUC to determine how potential income tax expense reductions from the changes in federal income tax law will benefit
Idaho Power customers and affect IDACORP's and Idaho Power's financial condition and results of operations. Although not
expected by Idaho Power, if the regulatory decisions of the IPUC and OPUC result in significant reductions to Idaho Power
revenues in excess of any cash savings from the federal income tax law changes, it could adversely affect IDACORP's and
Idaho Power's cash flows from operations and potentially require Idaho Power to increase cash from financing activities. At this
time, the companies are unable to determine what impact the regulatory proceedings related to the Tax Cuts and Jobs Act will
have on future IDACORP and Idaho Power liquidity. See "Regulatory Matters" in this MD&A for more information on the
related regulatory proceedings.

(1) For additional information, see Note 4 – “Long-Term Debt” to the consolidated financial statements included in this report.
(2) Future interest payments are calculated based on the assumption that all debt is outstanding until maturity. For debt instruments with variable rates, interest
is calculated for all future periods using the rates in effect at December 31, 2017.
(3) The operating leases include right-of-way easements.
(4) Approximately $34 million of the amounts in operating leases, $80 million of the amounts in other purchase obligations, and $2 million of the amounts in
IDACORP only other long-term liabilities are contracts that do not specify terms related to expiration. As these contracts are presumed to continue
indefinitely, ten years of information, estimated based on current contract terms, has been included in the table for presentation purposes.
(5) Other purchase obligations also include Idaho Power's estimated proportionate funding obligation for goods and services under non-fuel purchase
agreements at its jointly-owned generation facilities. In some instances, Idaho Power is not a direct party to an underlying purchase agreement, but is
obligated under the instruments governing the joint ventures to reimburse the co-owner for payments the co-owner makes pursuant to the purchase agreement.
Those estimated amounts have been included in the table above.
(6) Idaho Power estimates pension contributions based on actuarial data. As of the date of this report, Idaho Power cannot estimate pension contributions
beyond 2022 with any level of precision, and amounts through 2022 are estimates only and are subject to change. For more information on pension and
postretirement plans, refer to Note 11 – "Benefit Plans" to the consolidated financial statements included in this report.
Dividends
The amount and timing of dividends paid on IDACORP’s common stock are within the discretion of IDACORP’s board of
directors. IDACORP's board of directors reviews the dividend rate periodically to determine its appropriateness in light of
IDACORP’s current and long-term financial position and results of operations, capital requirements, rating agency
considerations, contractual and regulatory restrictions, legislative and regulatory developments affecting the electric utility
industry in general and Idaho Power in particular, competitive conditions, and any other factors the board of directors deems
relevant. The ability of IDACORP to pay dividends on its common stock is dependent upon dividends paid to it by its
subsidiaries, primarily Idaho Power.
IDACORP has a dividend policy that provides for a target long-term dividend payout ratio of between 50 and 60 percent of
sustainable IDACORP earnings, with the flexibility to achieve that payout ratio over time and to adjust the payout ratio or to
deviate from the target payout ratio from time to time based on the various factors that drive IDACORP's board of directors'
dividend decisions. Notwithstanding the dividend policy adopted by IDACORP's board of directors, the dividends IDACORP
pays remain in the discretion of the board of directors who, when evaluating the dividend amount, will continue to take into
account the factors above, among others. In September of 2015, 2016, and 2017, IDACORP's board of directors voted to
increase the quarterly dividend to $0.51 per share, $0.55 per share, and $0.59 per share of IDACORP common stock,
respectively. IDACORP's dividends during 2017 were 53 percent of actual 2017 earnings.
For additional information relating to IDACORP and Idaho Power dividends, including restrictions on IDACORP’s and Idaho
Power’s payment of dividends, see Note 6 – “Common Stock” to the consolidated financial statements included in this report.
55
Contingencies and Proceedings
IDACORP and Idaho Power are involved in a number of litigation, alternative dispute resolution, and administrative
proceedings, and are subject to claims and legal actions arising in the ordinary course of business, that could affect their future
results of operations and financial condition. In many instances IDACORP and Idaho Power are unable to predict the outcomes
of the matters or estimate the impact the proceedings may have on their financial positions, results of operations, or cash flows.
Idaho Power is also actively monitoring various environmental regulations that may have a significant impact on its future
operations. Given uncertainties regarding the outcome, timing, and compliance plans for these environmental matters, Idaho
Power is unable to determine the financial impact of potential new regulations but does believe that future capital investment
for infrastructure and modifications to its electric generating facilities to comply with these regulations could be significant.
Off-Balance Sheet Arrangements
Through a self-bonding mechanism, Idaho Power guarantees its portion of reclamation activities and obligations at BCC, of
which IERCo owns a one-third interest. This guarantee, which is renewed annually with the Wyoming Department of
Environmental Quality, was $56.7 million at December 31, 2017, representing IERCo's one-third share of BCC's total
reclamation obligation of $170.1 million. BCC has a reclamation trust fund set aside specifically for the purpose of paying these
reclamation costs. At December 31, 2017, the value of the reclamation trust fund totaled $103.4 million. During 2017, the
reclamation trust fund made no distributions for reclamation activity costs associated with the BCC surface mine. BCC
periodically assesses the adequacy of the reclamation trust fund and its estimate of future reclamation costs. To ensure that the
reclamation trust fund maintains adequate reserves, BCC adds a per-ton surcharge to coal sales. Because of the existence of the
fund and the ability to apply a per-ton surcharge, the estimated fair value of this guarantee is minimal.
REGULATORY MATTERS
Introduction
Idaho Power's regulatory strategy takes into consideration short-term and long-term needs for rate relief and involves several
factors that can affect the timing of rate filings. These factors include, among others, in-service dates of major capital
investments, the timing of changes in major revenue and expense items, and customer growth rates. Idaho Power's most recent
general rate cases in Idaho and Oregon were filed during 2011, and Idaho Power filed a large single-issue rate case for the
Langley Gulch power plant in Idaho and Oregon in 2012. These significant rate cases resulted in the resetting of base rates in
both Idaho and Oregon during 2012. Idaho Power also reset its base-rate power supply expenses in the Idaho jurisdiction for
purposes of updating the collection of costs through retail rates in 2014 but without a resulting net increase in rates. Between
general rate cases, Idaho Power relies upon customer growth, power cost adjustment mechanisms, tariff riders, and other
mechanisms to reduce the impact of regulatory lag, which refers to the period of time between making an investment or
incurring an expense and recovering that investment or expense and earning a return. Management's regulatory focus in recent
years has been largely on regulatory settlement stipulations and the design of rate mechanisms. Idaho Power continues to assess
the need and timing of filing a general rate case in its two retail jurisdictions, based on its consideration of the factors described
above, but does not anticipate filing a general rate case in 2018.

Notable Retail Rate Changes in Idaho and Oregon
Included in the table that follows are notable regulatory developments during 2017, 2016, and 2015 that affected Idaho Power's
results for the periods. Also refer to Note 3 - "Regulatory Matters" to the consolidated financial statements included in this
report for a description of regulatory mechanism and associated orders of the IPUC and OPUC, which should be read in
conjunction with the discussion of regulatory matters in this MD&A.

(1) The annual amount collected in rates is typically not recovered on a linear basis (i.e., 1/12th per month), and is instead recovered in proportion to general
business sales volumes. The rate changes for the Idaho PCA and FCA are applicable only for one-year periods.
(2) 2017 Idaho PCA rates reflect the application of $13.0 million of surplus Idaho energy efficiency rider funds.
(3) 2016 Idaho PCA rates reflect the application of (a) a customer rate credit of $3.2 million for sharing of revenues with customers for the year 2015 under the
terms of an October 2014 settlement stipulation and (b) $4.0 million of surplus Idaho energy efficiency rider funds.
(4) 2015 Idaho PCA rates reflect the application of (a) a customer rate credit of $8.0 million for sharing of revenues with customers for the year 2014 under the
terms of a December 2011 settlement stipulation, (b) a $1.5 million customer benefit relating to a change to the PCA methodology described below, and
(c) $4.0 million of surplus Idaho energy efficiency rider funds.
Idaho and Oregon General Rate Cases and Base Rate Adjustments
Effective January 1, 2012, Idaho Power implemented new Idaho base rates resulting from the regulatory settlement of a general
rate case filing Idaho Power made in 2011. In the general rate case, the IPUC issued an order approving a settlement stipulation
that provided for an overall 7.86 percent authorized rate of return on an Idaho-jurisdiction rate base of approximately $2.36
billion. The settlement stipulation resulted in a $34.0 million overall increase in Idaho Power's annual Idaho-jurisdictional base
rate revenues. Neither the IPUC's order nor the settlement stipulation specified an authorized rate of return on equity.
Effective March 1, 2012, Idaho Power implemented new Oregon base rates resulting from its receipt of an order from the
OPUC approving a settlement stipulation in its general rate case proceedings that provided for a $1.8 million base rate revenue
increase, a rate of return on equity of 9.9 percent, and an overall rate of return of 7.757 percent in the Oregon jurisdiction.
Idaho and Oregon base rates were subsequently adjusted again in 2012, in connection with Idaho Power's completion of the
Langley Gulch power plant. In June 2012, the IPUC issued an order approving a $58.1 million increase in annual Idaho-
jurisdiction base rate revenues, effective July 1, 2012, for inclusion of the investment and associated costs of the plant in rates.
The order also provided for a $335.9 million increase in Idaho rate base. On September 20, 2012, the OPUC issued an order
approving a $3.0 million increase in annual Oregon jurisdiction base rate revenues, effective October 1, 2012, for inclusion of
the investment and associated costs of the plant in Oregon rates.
In March 2014, the IPUC issued an order approving Idaho Power's application requesting an increase of approximately $106
million in the normalized or "base level" net power supply expense on a total-system basis to be used to update base rates and
in the determination of the PCA rate that became effective June 1, 2014. Approval of the order removed the Idaho-jurisdictional
portion of those expenses (approximately $99 million) from collection via the PCA mechanism and instead results in collecting
that portion through base rates.
Valmy Base Rate Adjustment Settlement Stipulations and Depreciation Rate Settlement Stipulations
In May 2017, the IPUC approved a settlement stipulation allowing accelerated depreciation and cost recovery for the Valmy
Plant. The settlement stipulation provides for an increase in Idaho jurisdictional revenues of $13.3 million per year, and (1)
levelized collections and associated cost recovery through December 2028, (2) accelerated depreciation on unit 1 through 2019
57
and unit 2 through 2025, (3) Idaho Power to use prudent and commercially reasonable efforts to end its participation in the
operation of unit 1 by the end of 2019 and unit 2 by the end of 2025, and (4) a filing no later than December 31, 2019 that
would include actual and planned incremental investments in unit 2, including updated financial analysis regarding the lowest
costs options for unit 2. The costs intended to be recovered by the increased jurisdictional revenues include current investments
as of May 31, 2017 in both units, forecasted unit 1 investments from 2017 through 2019, and forecasted decommissioning costs
for unit 1 and unit 2, offset by forecasted operation and maintenance costs savings. The settlement stipulation also provides for
the regulatory accrual or deferral of the difference between actual revenue requirements and levelized collections, and provides
for the regulatory accrual or deferral of the difference between actual costs incurred (including accelerated depreciation expense
on unit 1 through 2019 and unit 2 through 2025) compared with costs permitted to be recovered during the cost recovery period
specified in the settlement stipulation (including depreciation expense through 2028). If actual costs incurred differ from
forecasted amounts included in the settlement stipulation, collection or refund of any differences would be subject to regulatory
approval.
In June 2017, the OPUC also approved a settlement stipulation allowing for accelerated depreciation of units 1 and 2 through
December 31, 2025, cost recovery of incremental Valmy Plant investments through May 31, 2017, and forecasted
decommissioning costs. The settlement stipulation provides for an increase in the Oregon jurisdictional revenue requirement of
$1.1 million, effective July 1, 2017, with yearly adjustments, if warranted.
In May 2017, the IPUC and OPUC approved settlement stipulations related to revised depreciation rates for Idaho Power's
other electric plant in service, and adjusted base rates in Oregon to reflect the revised depreciation rates applied to electric
plant-in-service based on balances from the most recent general rate case. These settlement stipulations provided for new
depreciation rates to go into effect on June 1, 2017, with no significant resulting increase in revenue.
In 2017, the settlement stipulations increased general business revenue collections, general business revenue accruals, net
depreciation expense, and income tax expense, including plant-related flow-through tax adjustments. Compared with Idaho
Power’s estimate of what ongoing net income would have been without the settlement stipulations, the settlement stipulations
are expected to increase after-tax net income by approximately $5 million on an annual basis. Idaho Power expects the ongoing
annual benefit to net income from the Valmy Plant settlement stipulations to decline slightly each year through 2028, primarily
due to the annual decline in Valmy Plant-related rate base, which is expected to be fully depreciated by December 31, 2028.
Non-Base Rate Idaho Regulatory Settlement Stipulations
Settlement Stipulation for 2012 to 2014: In December 2011, the IPUC issued an order, separate from the then-pending Idaho
general rate case proceeding, approving a settlement stipulation that allowed Idaho Power to, in certain circumstances, amortize
additional ADITC if Idaho Power's actual Idaho ROE for 2012, 2013, or 2014 was less than 9.5 percent, to help achieve a 9.5
percent Idaho ROE for the applicable year. Under the December 2011 settlement stipulation, when Idaho Power's actual Idaho
ROE for any of those years exceeded 10.0 percent, Idaho Power was required to share a portion of its Idaho-jurisdiction
earnings with Idaho customers.
Settlement Stipulation for 2015 to 2019: In October 2014, the IPUC issued an order approving an extension, with
modifications, of the terms of the December 2011 settlement stipulation for the period from 2015 through 2019, or until the
terms are otherwise modified or terminated by order of the IPUC or the full $45 million of additional ADITC contemplated by
the settlement stipulation has been amortized. The more specific terms and conditions of the October 2014 settlement
stipulation are described in Note 3 - "Regulatory Matters - Notable Idaho Regulatory Matters" to the consolidated financial
statements included in this report. IDACORP and Idaho Power believe that the terms allowing amortization of additional
ADITC in the October 2014 settlement stipulation provide the companies with a greater degree of earnings stability than would
be possible without the terms of the stipulation in effect.
In 2017, Idaho Power's Idaho ROE was between 9.5 and 10.0 percent, and thus Idaho Power recorded no additional ADITC
amortization and no provision for sharing with customers. Accordingly, at December 31, 2017, the full $45 million of additional
ADITC remains available for future use under the terms of the settlement stipulation.

On December 22, 2017, the Tax Cuts and Jobs Act was signed into law, which lowered the corporate federal income tax rate
from 35 percent to 21 percent and modified or eliminated certain federal income tax deductions for corporations. On January
17, 2018, the IPUC issued an order requiring utilities within its jurisdiction, including Idaho Power, to 1) record a deferred
regulatory liability for the estimated Idaho-jurisdictional share of financial benefits after January 1, 2018, from the changes in
federal income tax law and 2) to file a report with the IPUC by March 30, 2018, identifying and quantifying the income tax
changes along with proposed tariff schedule changes. The IPUC order requires Idaho Power to estimate the income tax changes
by comparing actual 2017 federal income tax expense components with what those federal income tax components would have
been if the Tax Cuts and Jobs Act had been effective for the full year of 2017. Idaho Power is currently working to comply with
the IPUC order.
On December 29, 2017, Idaho Power filed an application with the OPUC requesting authority to defer for later ratemaking
treatment the Oregon jurisdictional earnings in excess of the currently authorized Oregon jurisdictional rate of return on equity
that may result from the Tax Cuts and Jobs Act. On December 29, 2017, OPUC Staff also filed an application with the OPUC
requesting authority to defer for later ratemaking treatment the difference between Idaho Power’s current retail rates and its
current retail rates inclusive of the impact of the Tax Cuts and Jobs Act.
Idaho Power is working with the IPUC and OPUC to determine how potential income tax expense reductions from the changes
in federal income tax law may benefit Idaho Power customers and affect IDACORP's and Idaho Power's financial condition and
results of operations. The method through which potential cost savings may be accrued for the benefit of customers, including
potential reductions to customer rates and to regulatory deferrals, will require approval from the IPUC and OPUC.
Idaho Energy Efficiency Rider
On an annual basis, Idaho Power applies to the IPUC for an order designating Idaho Power’s prior calendar year Idaho Energy
Efficiency Rider (Idaho Rider) funded expenses as prudently incurred. In October 2017, the IPUC issued its order determining
that the 2011 - 2016 incremental Idaho Rider funded labor expenses of $1.9 million were prudently incurred. In its order, the
IPUC also authorized actual Idaho Rider funded wage increases after 2016. The prudence order resulted in a $2.4 million
increase in operating income in 2017. For more information on the order and its impacts on results, see Note 3 - "Regulatory
Matters" to the consolidated financial statements included in this report.
Customer-Owned Generation Filing
On July 27, 2017, Idaho Power filed an application with the IPUC requesting the creation of two new classes for residential and
small general service customers who choose to install customer-owned generation on or after January 1, 2018. If approved as
proposed, Idaho Power does not, as of the date of this report, anticipate that the creation of these new rate classes would impact
in the near term the current rates for the approximately 1,700 residential and small general service customers and applicants
who currently take or are requesting net metering services from Idaho Power for their customer-owned generation.
59
Deferred Net Power Supply Costs
Deferred power supply costs represent certain differences between Idaho Power's actual net power supply costs and the costs
included in its retail rates, the latter being based on annual forecasts of power supply costs. Deferred power supply costs are
recorded on the balance sheets for future recovery or refund through customer rates. Idaho Power's power cost adjustment
mechanisms in its Idaho and Oregon jurisdictions provide for annual adjustments to the rates charged to retail customers. The
power cost adjustment mechanisms and associated financial impacts are described in "Results of Operations" in this MD&A
and in Note 3 - "Regulatory Matters" to the consolidated financial statements included in this report.
Factors that have influenced power cost adjustment rate changes in recent years include year-to-year volatility in hydroelectric
generation conditions, market energy prices and the volume of off-system sales, power purchase costs from renewable energy
projects, and revenue sharing under Idaho regulatory settlement stipulations. From year to year, these factors can vary
significantly, which can result in significant accruals and deferrals under the power cost adjustment mechanisms. The power
cost adjustment rate changes reflected in the table under the heading "Notable Retail Rate Changes in Idaho and Oregon" are
illustrative of the volatility of net power supply costs and the impact on power cost adjustment rates.

(1) Oregon power supply cost deferrals are subject to a statute that specifically limits rate amortizations of deferred costs to six percent of gross Oregon
revenue per year (approximately $3 million). Deferrals are amortized sequentially.
Recovery of Costs for Anticipated Participation in Western Energy Imbalance Market
In January 2017, the IPUC issued an order authorizing Idaho Power’s requested deferral accounting treatment for costs
associated with joining the Western EIM. Idaho Power can defer costs incurred until the earlier of when Idaho Power begins
recovery of the costs and the deferral balance or the end of 2018. Idaho Power anticipates that it will begin participating in the
Western EIM in April of 2018. The Western EIM is intended to reduce the power supply costs to serve customers through more
efficient dispatch of a larger and more diverse pool of resources, to integrate intermittent power from renewable generation
sources more effectively, and to enhance reliability.
In November 2017, Idaho Power filed an application with the IPUC requesting approval to establish an interim method of
recovery for costs associated with participation in the Western EIM. If the IPUC approves the application as filed, Idaho Power
intends to include $3.6 million in costs for recovery through the PCA, beginning June 1, 2018. Idaho Power has requested a
decision from the IPUC by March 31, 2018.

Open Access Transmission Tariff Rate Proceedings
Idaho Power uses a formula rate for transmission service provided under its OATT, which allows transmission rates to be
updated annually based primarily on financial and operational data Idaho Power files with the FERC. In August 2017, Idaho
Power filed its 2017 final transmission rate with the FERC, reflecting a transmission rate of $34.90 per kW-year, to be effective
for the period from October 1, 2017 to September 30, 2018. Idaho Power's final rate was based on a net annual transmission
revenue requirement of $130.4 million. The OATT rate in effect from October 1, 2016 to September 30, 2017, was $25.52 per
kW-year based on a net annual transmission revenue requirement of $127.4 million. The increase in the OATT rate was largely
attributable to an asset exchange transaction with one transmission customer, and the termination of legacy long-term
transmission service agreements and its impact on the transmission formula rate, which was fully incorporated in the new
formula rate, effective October 1, 2017. For more information on the new formula rate, refer to Transmission Revenues
Associated with Asset Exchange Transaction below in this "Regulatory Matters" section in this MD&A.
Historic OATT rate information is included in Note 3 - "Regulatory Matters" to the consolidated financial statements included
in this report.
Transmission Revenues Associated with Asset Exchange Transaction
Effective in October 2015, Idaho Power and PacifiCorp each transferred to the other certain interests in transmission-related
equipment. In connection with that transaction, the companies terminated or amended a number of long-term agreements
between Idaho Power and PacifiCorp related to the ownership and operation of transmission-related equipment and
transmission services. In 2014, Idaho Power collected approximately $8 million in transmission revenues under long-term
transmission agreements that were terminated in connection with the asset exchange transaction. As a result of the transaction
and termination of those long-term transmission agreements, Idaho Power's OATT rate increased; however, in accordance with
FERC's current formula rate methodology the increase phased in over two annual rate proceedings. The impact of the asset
exchange on the transmission formula rate was fully incorporated in the new formula rate, effective October 1, 2017.
In compliance with the IPUC's order approving the asset exchange transaction, Idaho Power submitted to the IPUC a request
for verification that its regulatory accounting method reflecting a symmetrical tracking of changes in transmission revenues
resulting specifically from the asset exchange with PacifiCorp complies with the IPUC’s order. As an alternative proposed by
Idaho Power to its symmetrical tracking, in August 2016, the IPUC ordered that any changes in transmission revenues resulting
from the asset exchange will be addressed, prospectively, in Idaho Power's next general rate case.
Relicensing of Hydroelectric Projects
Overview: Idaho Power, like other utilities that operate non-federal hydroelectric projects on qualified waterways, obtains
licenses for its hydroelectric projects from the FERC. These licenses have a term of 30 to 50 years depending on the size,
complexity, and cost of the project. The expiration dates for the FERC licenses for each of the facilities are included in Part I -
Item 2 - "Properties" in this report. Costs for the relicensing of Idaho Power's hydroelectric projects are recorded in construction
work in progress until a new multi-year license is issued by the FERC, at which time the charges are transferred to electric plant
in service. Idaho Power expects to seek recovery of relicensing costs and costs related to a new long-term license through the
regulatory process and, in December 2016, submitted a request for a determination of prudence of HCC relicensing costs,
which is described below. Relicensing costs of $268.7 million for the HCC, Idaho Power's largest hydroelectric complex and a
major relicensing effort, were included in construction work in progress at December 31, 2017. As of the date of this report, the
IPUC authorizes Idaho Power to include in its Idaho jurisdiction rates approximately $6.5 million annually ($10.7 million when
grossed-up for the effect of income taxes) of AFUDC relating to the HCC relicensing project. Collecting these amounts now
will reduce the amount collected in the future once the HCC relicensing costs are approved for recovery in base rates. As of
December 31, 2017, Idaho Power's regulatory liability for collection of AFUDC relating to the HCC was $120 million. In
addition to the discussion below, refer to "Environmental Matters" in this MD&A for a discussion of environmental compliance
under FERC licenses for Idaho Power's hydroelectric generating plants.
Hells Canyon Complex: The HCC, located on the Snake River where it forms the border between Idaho and Oregon, provides
approximately 68 percent of Idaho Power's hydroelectric generating nameplate capacity and 32 percent of its total generating
nameplate capacity. In July 2003, Idaho Power filed an application with the FERC for a new license in anticipation of the July
2005 expiration of the then-existing license. Since the expiration of that license, Idaho Power has been operating the project
under annual licenses issued by the FERC. In December 2004, Idaho Power and eleven other parties, including National Marine
Fisheries Service (NMFS) and U.S. Fish and Wildlife Service (USFWS), involved in the HCC relicensing process entered into
an interim agreement that addresses the effects of the ongoing operations of the HCC on Endangered Species Act (ESA) listed
61
species pending the relicensing of the project. In August 2007, the FERC Staff issued a final environmental impact statement
(EIS) for the HCC, which the FERC will use to determine whether, and under what conditions, to issue a new license for the
project. The purpose of the final EIS is to inform the FERC, federal and state agencies, Native American tribes, and the public
about the environmental effects of Idaho Power's operation of the HCC. Certain portions of the final EIS involve issues that
may be influenced by water quality certifications for the project under Section 401 of the Clean Water Act (CWA) and formal
consultations under the ESA, which remain unresolved.
In connection with its relicensing efforts, Idaho Power has filed water quality certification applications, required under Section
401 of the CWA, with the states of Idaho and Oregon requesting that each state certify that any discharges from the project
comply with applicable state water quality standards. Section 401 of the CWA requires that a state either approve or deny a
Section 401 water quality certification application within one year of the filing of the application or the state may be considered
to have waived its certification authority under the CWA. As a consequence, Idaho Power has been filing and withdrawing its
Section 401 certification applications with Oregon and Idaho on an annual basis while it has been working with the states to
identify measures that will provide reasonable assurance that discharges from the HCC will adequately address applicable water
quality standards. In the 2016 Section 401 certification application process, Oregon required Idaho Power to comply with fish
passage and reintroduction conditions. Idaho's water quality certification, however, provides that Idaho Power shall take no
action that may result in the reintroduction or establishment of spawning populations of any fish species into Idaho's waters
without consultation with and express approval of the State of Idaho. On November 30, 2016, Idaho Power filed a petition with
the FERC requesting that the FERC resolve the conflict between Oregon's and Idaho's conditions and declare that the FPA pre-
empts the Oregon state law. In January 2017, the FERC issued an order denying Idaho Power’s petition, stating that the petition
for a declaratory order was premature, cannot realistically be considered separately from the issue of the states’ certification
authority under the CWA Section 401, and raises issues that are beyond the FERC’s authority to decide. In February 2017,
Idaho Power sought rehearing before the FERC on the January 2017 order, which the FERC denied. On February 16, 2018,
Idaho Power filed an appeal of the FERC's January 2017 order with the D.C. Circuit Court.
In April 2017, the governors of Oregon and Idaho jointly requested that Idaho Power withdraw and resubmit its Section 401
certification applications in both states to allow the states additional time to negotiate a potential resolution of the disputed
issues. As of November 2017, the states were not able to resolve their differences timely enough within the one-year cycle,
requiring Idaho Power to again withdraw and resubmit its Section 401 certification applications in both states. Idaho Power
withdrew and refiled a 401 certification application on November 22, 2017. Idaho Power continues to work with the states
towards a mutually agreeable solution.
In September 2007, in connection with the issuance of its final EIS, the FERC notified the NMFS and the USFWS of its
determination that the licensing of the HCC was likely to adversely affect ESA-listed species, including the bull trout and fall
Chinook salmon and steelhead, under the NMFS's and USFWS's jurisdiction and requested that the NMFS and USFWS initiate
formal consultation under Section 7 of the ESA on the licensing of the HCC. Each of the NMFS and USFWS responded to the
FERC that the conditions relating to the licensing of the HCC were not fully described or developed in the final EIS as the
measures to address the water quality effects of the project were yet to be fully defined by the Section 401 certification process.
The NMFS and USFWS therefore recommended that formal consultation under the ESA be delayed until the Section 401
certification process is completed.
Idaho Power continues to work with Idaho and Oregon in the development of measures to provide reasonable assurance that
any discharges from the HCC will comply with applicable state water quality standards so that appropriate water quality
certifications can be issued for the project, and continues to cooperate with the USFWS, NMFS, and the FERC in an effort to
address ESA concerns. Idaho Power has begun construction of new aerated runners at the Brownlee project (part of the HCC) at
an estimated cost of $57 million. Two of four units were installed by the end of 2017 and Idaho Power plans to install the third
and fourth units in 2018 and 2019, respectively. Other measures that have been proposed or considered have included
modification of spillways at two dams in the HCC to address total dissolved gas issues, and upstream watershed improvements
or the installation of a temperature control structure to address water temperatures during a small portion of the year. If Idaho
Power is required to take these or other additional measures to satisfy relicensing requirements, it could add substantially to
project costs. Idaho Power continues to work with the Oregon and Idaho Departments of Environmental Quality on the water
quality certification issue and the water quality measures that will be required to obtain Section 401 certification.
As of the date of this report, Idaho Power is unable to predict the timing of issuance by the FERC of any license order or the
ultimate capital investment and ongoing operating and maintenance costs Idaho Power will incur in complying with any new
license. However, as of the date of this report, Idaho Power estimates that the annual costs it will incur to obtain a new long-
term license for the HCC, including AFUDC but excluding costs expected to be incurred for complying with the license after
issuance, are likely to range from $25 million to $35 million until issuance of the license, which Idaho Power estimates will
62
occur no earlier than 2022. In light of the costs incurred and the considerable passage of time, in December 2016, Idaho Power
filed an application with the IPUC requesting a determination that Idaho Power's expenditures of $220.8 million through year-
end 2015 on relicensing of the HCC were prudently incurred, and thus eligible for inclusion in retail rates in a future rate
proceeding. In December 2017, Idaho Power filed with the IPUC a settlement stipulation signed by Idaho Power, the IPUC
Staff, and a third party intervenor recognizing that a total of $216.5 million in HCC relicensing expenditures and other related
costs were reasonably incurred, and therefore should be eligible for inclusion in customer rates at a later date. The settlement
stipulation is subject to review and approval by the IPUC. As a result of filing the settlement stipulation, Idaho Power recorded
a $5.0 million pre-tax charge in 2017. As of the date of this report, the IPUC has not issued an order in this matter.
2017 Integrated Resource Plan
The IPUC and OPUC require that Idaho Power prepare biennially an IRP. The IRP seeks to forecast Idaho Power's loads and
resources for a 20-year period, analyzes potential supply-side, demand-side, and transmission options, and identifies potential
near-term and long-term actions. Idaho Power filed its most recent IRP with the IPUC and OPUC in June 2017. In October
2017, OPUC Staff and third party intervenors filed comments to the 2017 IRP with the OPUC, requesting additional
information related to the need for the Boardman-to-Hemingway transmission line and Idaho Power's forecasts, among other
items. Idaho Power filed its response to the comments and supplemental information for the 2017 IRP in December 2017. On
February 9, 2018, the IPUC issued an order acknowledging the 2017 IRP. As of the date of this report, the OPUC has not issued
an order acknowledging the 2017 IRP.
Renewable Energy Standards and Contracts
Renewable Portfolio Standards: Numerous proponents have introduced legislation in the U.S. Congress that would require
electric utilities to obtain a specified percentage of their electricity from renewable sources, commonly referred to as a
"renewable portfolio standard" or "RPS." However, as of the date of this report no federal or State of Idaho RPS is in effect.
Idaho Power will be required to comply with a five- or ten-percent RPS in Oregon beginning in 2025 (depending on loads at
that time), and Idaho Power expects to meet either RPS requirement with Renewable Energy Certificates (REC) obtained from
the purchase of power from the Elkhorn Valley wind project.
Pursuant to an IPUC order, Idaho Power is selling its near-term RECs and returning to customers their share (shared 95 percent
with customers in the Idaho jurisdiction) of those proceeds through the PCA. For the years ended December 31, 2017, 2016,
and 2015, Idaho Power's REC sales totaled $2.3 million, $1.0 million, and $1.8 million, respectively.
Were Idaho Power to be subject to additional RPS legislation, it may cease in full or in part the sale of RECs it receives, seek to
obtain RECs from additional projects, generate RECs from any REC-generating facilities it owns or may be required to
construct in light of an RPS, or purchase RECs in the market. Historically, Idaho Power has generally not received the RECs
associated with PURPA projects. However, an order issued by the IPUC in 2012 provides that Idaho Power will own a portion
of the RECs generated by some PURPA projects. The required purchase of additional RECs to meet RPS requirements would
increase Idaho Power's costs, which Idaho Power expects would be wholly or largely passed on to customers through rates and
the power cost adjustment mechanisms.
Renewable and Other Energy Contracts: Idaho Power has contracts for the purchase of electricity produced by third-party
generation facilities, most of which produce energy with the use of renewable generation sources such as wind, solar, biomass,
small hydroelectric and geothermal. The majority of these contracts are entered into as mandatory purchases under PURPA. As
of December 31, 2017, Idaho Power had contracts to purchase energy from 127 on-line PURPA projects. An additional three
contracts are with non-PURPA projects, including the Elkhorn Valley wind project with a 101-MW nameplate capacity. The
following table sets forth, as of December 31, 2017, the resource type and nameplate capacity of Idaho Power's signed
agreements for power purchases from PURPA and non-PURPA generating facilities. These agreements have original contract
terms ranging from one to 35 years.

ENVIRONMENTAL MATTERS
Overview
Idaho Power's activities are subject to a broad range of federal, state, regional, and local laws and regulations designed to
protect, restore, and enhance the environment, including the CAA, the CWA, the Resource Conservation and Recovery Act, the
Toxic Substances Control Act, the Comprehensive Environmental Response, Compensation and Liability Act, and the ESA,
among other laws. These laws are administered by a number of federal, state, and local agencies. In addition to imposing
continuing compliance obligations and associated costs, these laws and regulations provide authority to regulators to levy
substantial penalties for noncompliance, injunctive relief, and other sanctions. Idaho Power's three co-owned coal-fired power
plants and three natural gas-fired combustion turbine power plants are subject to many of these regulations. Idaho Power's 17
hydroelectric projects are also further subject to a number of water discharge standards and other environmental requirements.
Compliance with current and future environmental laws and regulations may:
•
•
•
•
•
increase the operating costs of generating plants;
increase the construction costs and lead time for new facilities;
require the modification of existing generating plants, which could result in additional costs;
require the curtailment or shut-down of existing generating plants; or
reduce the output from current generating facilities.
Current and future environmental laws and regulations will increase the cost of operating fossil fuel-fired generation plants and
constructing new generation and transmission facilities, in large part through the substantial cost of permitting activities and the
required installation of additional pollution control devices. In many parts of the United States, some higher-cost, high-emission
coal-fired plants have ceased operation or the plant owners have announced a near-term cessation of operation, as the cost of
compliance makes the plants uneconomical to operate. The decision to agree to cease operation of the Boardman coal-fired
plant, in which Idaho Power owns a 10 percent interest, by the end of 2020, was based in part on the significant future cost of
compliance with environmental laws and regulations. The decision to pursue an end to participation in coal-fired operations at
the Valmy Plant was also based primarily on the economics of operating the plant. Additionally, in light of the uncertainty
resulting from pending environmental regulation and the substantial estimated cost of selective catalytic reduction equipment
(SCR) installation, Idaho Power is assessing whether to move forward with the installation of SCR on units 1 and 2 at the Jim
Bridger power plant. Beyond increasing costs generally, these environmental laws and regulations could affect IDACORP's and
Idaho Power's results of operations and financial condition if the costs associated with these environmental requirements and
early plant retirements cannot be fully recovered in rates on a timely basis.
Part I, Item 1 - “Business - Utility Operations - Environmental Regulation and Costs” in this report includes a summary of
Idaho Power's expected capital and operating expenditures for environmental matters during the period from 2018 to 2020.
64
Given the uncertainty of future environmental regulations and technological advances, Idaho Power is unable to predict its
environmental-related expenditures beyond 2020, though they could be substantial. Furthermore, several executive orders
issued in 2017 concerning environmental regulations, as described below, could result in significant changes in, and uncertainty
with respect to, legislation, regulation, and government policy regarding environmental matters. Idaho Power may delay
making operational changes or environmental-related expenditures while such changes are pending to avoid implementing
uncertain laws, rules, and policies.
Executive Orders on Environmental Matters
In March 2017, an executive order was issued directing the U.S. Environmental Protection Agency (EPA) to review the Clean
Power Plan (CPP), the greenhouse gas new source performance standards (GHG NSPS), and the proposed Federal
Implementation Plan (FIP) for CPP and, if appropriate, to propose rules suspending, revising, or rescinding the CPP, GHG
NSPS, and proposed FIP within 45 to 120 days after the date of the order. The order also directed the Secretary of the Interior to
lift the moratorium on federal land for coal leasing activities and revoke certain Obama Administration directives regarding the
nature and extent of mitigation required for projects on federal lands. The order also addressed other climate-related issues,
including rescinding the technical support documents that estimate the social cost of carbon, rescinding the National
Environmental Policy Act (NEPA) guidance on greenhouse gases, and rescinding climate-related actions undertaken by the
previous presidential administration, among other issues. Shortly after the orders were issued, the EPA notified each state’s
governor that if any deadlines under the CPP become relevant in the future, the EPA will toll its requirement for states to
comply with the regulation. In October 2017, the EPA announced a proposal to repeal the CPP, and in December 2017, provided
an advance notice of rulemaking, asking for public input in early 2018 on a rule to replace the CPP. The proposed replacement
rule focuses on limiting pollution reduction measures to those measures that can be applied at the energy source. As of the date
of this report and in light of these executive actions, Idaho Power is uncertain whether and to what extent the replacement CPP
may impact its operations in the near term.
In August 2017, another executive order was issued to accelerate federal agencies' environmental review and permitting for
major infrastructure projects. The outcome of the EPA’s and other federal agencies' review of regulations covered by the
executive orders is difficult to predict. Changes to or elimination of regulations may lower Idaho Power's costs of operating and
maintaining fossil fuel-fired generation plants and transmission lines, due to the reduction of potential environmental
infrastructure upgrades or reduction or elimination of permitting requirements. The executive orders and resulting federal
regulations could, on the other hand, be affected by Congressional action and challenged in court. Further, state and local
governmental authorities could choose to replace the federal regulations or bolster environmental compliance and enforcement
efforts at the local level, and therefore, Idaho Power is uncertain whether and to what extent the orders could affect its
operations and environmental-related expenditures. Idaho Power plans to continue to monitor actions associated with or
resulting from the executive orders.
Endangered Species Act Matters
Overview: The listing of a species of fish, wildlife, or plants as threatened or endangered under the ESA may have an adverse
impact on Idaho Power's ability to construct generation, transmission, or distribution facilities or relicense or operate its
hydroelectric facilities. When a species is added to the federal list of threatened and endangered species, it is protected from
“take,” which is defined to include harming the species. The ESA directs that, concurrent with a designation of a threatened or
endangered species, and where prudent and determinable, the applicable agencies also designate “any habitat of such species
which is then considered to be critical habitat.” The ESA also provides that each federal agency must ensure that any action
they authorize, fund, or carry out is not likely to jeopardize the continued existence of a listed species or result in the
destruction or adverse modification of its critical habitat. If an action is determined to result in adverse modification of critical
habitat, the federal agency must adopt changes to the proposed action to avoid the adverse modification. These changes are
often quite extensive and can affect the size, scope, and even the feasibility of a project moving forward. In February 2016, the
U.S. Fish and Wildlife Service (USFWS) and the NMFS issued a set of regulatory and policy changes relating to critical habitat
and adverse modification determinations under the ESA. While the ultimate impact of implementation of those changes is yet to
be determined, taken as a whole, Idaho Power believes that the changes could result in the applicable agencies having greater
authority in making designations of critical habitat and could increase the likelihood of adverse modification determinations.
The construction of generation, transmission, or distribution facilities and the relicensing of Idaho Power's hydroelectric
projects can be federally authorized actions that fall under the ESA. There are a number of threatened or endangered species
within Idaho Power's service area and within or near proposed transmission line routes, including the slickspot peppergrass.
Further, there are a number of ESA-listed fish and other aquatic species located in waterways in which Idaho Power has
hydroelectric facilities, including fall Chinook salmon, bull trout, Bliss Rapids snail, and Snake River physa snail. To date,
65
efforts to protect these and other listed species have not significantly affected generation levels or operating costs at any of
Idaho Power's hydroelectric facilities. However, the ongoing relicensing of the HCC presents endangered species and fisheries
issues that may require operational adjustments and could adversely impact the amount of output from hydroelectric dams,
potentially causing Idaho Power to rely on more expensive sources for power generation or market purchases.
Developments in Regulation of Sage Grouse Habitat: In February 2016, a lawsuit was filed in the U.S. District Court of Idaho
challenging the BLM's sage grouse resource management and land use plan revisions that became effective in 2015 under the
Federal Land Policy and Management Act. The lawsuit challenges the plans and associated environmental impact statements
across the sage grouse range and alleges that the plans fail to ensure that sage grouse populations and habitats will be protected
and restored in accordance with the best available science and legal mandates. Further, the complaint challenges certain
exemptions provided for the Boardman-to-Hemingway and Gateway West transmission line projects. Idaho Power has
intervened in the proceedings in an effort to support the exemptions provided for in the BLM's plans. If the exemptions are
overturned, Idaho Power may be required to re-route the projects, which could lead to substantially higher construction and
permitting costs and could delay construction.
In May 2016, a separate lawsuit was filed in the U.S. District Court of North Dakota, challenging the BLM's sage grouse
resource management and land use plan revisions, including the exemptions provided for the Boardman-to-Hemingway and
Gateway West transmission line projects. In October 2016, the plaintiffs amended their complaint to no longer challenge the
exemptions; however, in December 2016, the North Dakota court transfered claims challenging certain Idaho land use plan
amendments to the U.S. District Court for the District of Columbia. Idaho Power is participating in the proceedings in an effort
to protect its interests.
In June 2017, the Secretary of the Interior issued an order directing the BLM to review the 2015 sage grouse resource
management and land use plan revisions and to identify provisions that may require modification or rescission to address
energy and other development of public lands. In October 2017, the Secretary of the Interior issued a notice of intent declaring
the Department of the Interior’s intent to consider amending the 2015 sage grouse resource management and land use plan
revisions. As of the date of this report, the above lawsuits are stayed as the parties and the courts consider the Department of the
Interior’s review of the sage grouse resource management and land use plan revisions.
ESA Issues Related to Specific Projects:
Hells Canyon Relicensing Project: In 2007, the FERC requested initiation of formal consultation under the ESA with the NMFS
and the USFWS regarding potential effects of HCC relicensing on several listed aquatic and terrestrial species. Formal
consultation has yet to be initiated and the NMFS and the USFWS continue to gather and consider information relative to the
effects of relicensing on relevant ESA listed species. Idaho Power continues to cooperate with the USFWS, the NMFS, and the
FERC in an effort to address ESA concerns. In December 2004, Idaho Power and eleven other parties, including NMFS and the
USFWS, entered into an interim agreement that addresses the effects of the ongoing operations of the HCC on ESA listed
species pending the relicensing of the project. At the conclusion of formal consultation and with the issuance of biological
opinions by the NMFS and the USFWS and an operating license by the FERC, Idaho Power may be required to implement
additional measures or further modify or adjust operations to comply with Section 7 of the ESA. The issuance of a final
biological opinion during 2018 is unlikely.
Boardman-to-Hemingway and Gateway West Transmission Projects: In August 2016, the USFWS re-instated the threatened
species status of slickspot peppergrass. Most of the species are located on federal land. Idaho Power expects the listing of the
slickspot peppergrass and its existence within or near the proposed routes for the Boardman-to-Hemingway and Gateway West
transmission line projects to continue to impact the cost and timing of permitting and construction of the projects, as it requires
an ESA Section 7 consultation. The USFWS has also indicated it intends to designate critical habitat for the species. If critical
habitat is designated within the vicinity of the transmission line projects, Idaho Power expects that the designation could
increase the cost of obtaining permits for the projects and could further delay the in-service date of the projects.
Endangered Species Act and National Environmental Policy Act Developments: In May 2016, the United States District
Court for the District of Oregon issued an opinion finding that in the context of hydroelectric facilities owned and operated by
the U.S. Army Corps of Engineers and located on the lower Snake River, National Oceanic and Atmospheric Administration's
National Marine Fisheries Service (NOAA Fisheries) violated the ESA by using improper standards, failing to consider
adequately the impact of climate change on habitat conditions, and placing undue reliance on unproven, future federal habitat
conservation measures, particularly to the degree that the success of the measures could be undermined by climate change. The
court also found that other federal agencies violated the National Environmental Policy Act (NEPA) by failing to prepare a
comprehensive environmental impact statement on implementation of the conservation measures ordered by NOAA Fisheries,
66
including analysis of the measures directed by NOAA Fisheries and other reasonable alternatives. The court’s opinion and its
emphasis on a climate change-driven analysis element, if generalized to other situations, could require ESA-driven avoidance,
minimization, and compensatory mitigation efforts to incorporate surplus measures to ensure species’ protection, which could
result in considerable increases in cost beyond the cost of additional analysis in the NEPA process. In September 2016, federal
agencies initiated an environmental impact statement process to examine hydroelectric dams on the lower Snake River, which
Idaho Power expects will take place over a five-year period. None of Idaho Power’s hydroelectric facilities are included in the
studies.
Climate Change and the Regulation of Greenhouse Gas Emissions
Overview: Long-term climate change could significantly affect Idaho Power's business in a variety of ways, including:
•
•
•
•
•
changes in temperature and precipitation could affect customer demand and energy loads;
extreme weather events, wildfires, drought, and other natural phenomena and natural disasters could increase service
interruptions, outages, maintenance costs, and the need for additional backup systems, and can affect the supply of,
and demand for, electricity and natural gas, which may impact the price of those and other commodities;
changes in the amount and timing of snowpack and stream flows could affect hydroelectric generation;
legislative and/or regulatory developments related to climate change could affect plants and operations, including
restrictions on the construction of new generation resources, the expansion of existing resources, or the operation of
generation resources; and
consumer preference for, and resource planning decisions requiring, renewable or low GHG-emitting sources of
energy could impact usage of existing generation sources and require significant investment in new generation and
transmission infrastructure.
Federal and state regulations pertaining to GHG emissions under the CAA have raised uncertainty about the future viability of
fossil fuels, most notably coal, as an economical energy source for new and existing electric generation facilities because many
new technologies for reducing CO2 emissions from coal, including carbon capture and storage, are still in the development stage
and are not yet proven. Stringent emissions standards could result in significant increases in capital expenditures and operating
costs, which may accelerate the retirement of coal-fired units and create power system reliability issues. Some higher-cost,
high-emission coal-fired plants have ceased operation or the plant owners have announced a near-term cessation of operation,
as the cost of compliance makes the plants uneconomical to operate, particularly in light of continued low natural gas prices
that decrease the cost to operate natural gas-fired power plants.
A variety of factors contribute to the financial, regulatory, and logistical uncertainties related to GHG reductions. These include
the specific GHG emissions limits imposed, the timing of implementation of these limits, the level of emissions allowances
allocated and the level that must be purchased, the purchase price of emissions allowances, the development and commercial
availability of technologies for renewable energy and for the reduction of emissions, the degree to which offsets may be used
for compliance, provisions for cost containment (if any), the impact on coal and natural gas prices, and the timing and amount
of cost recovery through rates. Accordingly, Idaho Power cannot predict the effect on its results of operations, financial
position, or cash flows of any GHG emission or other climate change requirements that may be adopted, although the costs to
implement and comply with any such requirements could be substantial. A more detailed discussion of legislative and
regulatory developments related to climate change follows.
National GHG Initiatives; Clean Power Plan: The EPA has been active in the regulation of GHGs. The EPA's endangerment
finding in 2009 that GHGs threaten public health and welfare resulted in the enactment of a series of EPA regulations to address
GHG emissions.
In May 2010, the EPA issued the “Tailoring Rule,” which set thresholds for GHG emissions that define when permits are
required for new and existing industrial facilities. While the rule is complex, Idaho Power believes that its owned and co-owned
fossil fuel-fired generation plants are, as of the date of this report, in compliance with the GHG Tailoring Rule.
In June 2014, the EPA released, under Section 111(d) of the CAA, a proposed rule for addressing GHG from existing fossil
fuel-fired electric generating units (EGUs). The proposed rule was intended to achieve a 30 percent reduction in CO2 emissions
from the power sector by 2030. On August 3, 2015, the EPA released the final rule under Section 111(d) of the CAA, referred to
as the Clean Power Plan (CPP), which requires states to adopt plans to collectively reduce 2005 levels of power sector CO2
emissions by 32 percent by the year 2030. The final rule provides states until September 2018 to submit implementation plans,
phasing in several compliance periods beginning in 2022 and achieving the final emissions goals by 2030. In October 2017, the
EPA announced a proposal to repeal the CPP, and in December 2017 provided an advance notice of rulemaking, asking for
67
public input in early 2018 on a rule to replace the CPP. The proposed replacement rule focuses on limiting pollution reduction
measures to those measures that can be applied at the energy source.
Because the rule is premised on state implementation plans, the terms of which Idaho Power does not control, and due to the
existing and potential changes in legislation, regulation, and government policy with respect to environmental matters as a
result of the presidential administration's executive orders and the EPA's proposal to repeal and replace the CPP discussed
above, as of the date of this report and in light of these executive actions, Idaho Power is uncertain whether and to what extent
the replacement CPP may impact its operations in the near term.
State GHG Initiatives and Idaho Power’s Voluntary GHG Reduction Initiative: In August 2007, the Oregon legislature
enacted legislation setting goals of reducing GHG levels to 10 percent below 1990 levels by 2020 and at least 75 percent below
1990 levels by 2050. Oregon imposes GHG emission reporting requirements on facilities emitting 2,500 metric tons or more of
CO2 equivalent annually. The Boardman coal-fired power plant located in Oregon, in which Idaho Power is a 10-percent owner,
is subject to and in compliance with Oregon's GHG reporting requirements but is scheduled to cease coal-fired operations in
2020.
In Oregon, legislation referred to as the Oregon Clean Electricity and Coal Transition Plan was enacted in March 2016, and
requires certain Oregon utilities to remove coal-fired generation from their Oregon retail rates by 2030. Oregon utilities would
be permitted to sell the output of coal-fired plants into the wholesale market or reallocate such plants to other states. To the
extent Idaho Power is subject to the legislation, it plans to seek recovery, through the ratemaking process, of operating and
capitalized costs related to its coal-fired generation assets and removal of any of those assets from Oregon rate base.
The State of Idaho has not passed legislation specifically regulating GHGs. Wyoming and Nevada similarly have not enacted
legislation to regulate GHG emissions and do not have a reporting requirement, but they are members of the Climate Registry, a
national, voluntary GHG emission reporting system. The Climate Registry is a collaboration aimed at developing and managing
a common GHG emission reporting system across states, provinces, and tribes to track GHG emissions nationally. All states for
which Idaho Power has traditional fuel generating plants (i.e. Idaho, Oregon, Wyoming, and Nevada) are members of the
Climate Registry. Idaho Power is engaged in voluntary GHG emissions intensity reduction efforts, which is discussed in Part I,
Item 1 - “Business - Utility Operations - Environmental Regulation and Costs."
Clean Air Act Matters
Overview: In addition to the CAA developments related to GHG emissions described above, several other regulatory programs
developed under the CAA apply to Idaho Power. These include the final Mercury and Air Toxics Standards (MATS), National
Ambient Air Quality Standards (NAAQS), New Source Review / Prevention of Significant Deterioration (NSR/PSD)
Rules, and the Regional Haze Rule.
MATS Implementation: The final MATS rule under the CAA, previously referred to as the Utility MACT Rule, was issued in
February 2012. The final rule established emission limits for hazardous air pollutants from new and existing coal-fired and oil-
fired steam electric generating units. The MATS rule provided that sources must be in compliance with emission limits by April
2015. Idaho Power and the plant co-owners have installed mercury continuous emission monitoring systems on all of the coal-
fired units at the Jim Bridger, Boardman, and North Valmy coal-fired generating plants, along with control technology to reduce
mercury, acid gases, and particulate matter emissions for purposes of compliance with the MATS rule. Idaho Power believes
that as of the date of this report, the coal-fired plants are in compliance with the MATS rule. Legal challenges relating to the
MATS rule, to which Idaho Power is not a party and pursuant to which the EPA is performing a court-mandated cost analysis
for the rule, are pending.
68
National Ambient Air Quality Standards: The CAA requires the EPA to set ambient air quality standards for six "criteria"
pollutants considered harmful to public health and the environment. These six pollutants are carbon monoxide, lead, ozone,
particulate matter, nitrogen dioxide, and sulfur dioxide. States are then required to develop emission reduction strategies
through State Implementation Plans, or SIPs, based on attainment of these ambient air quality standards. Recent developments
and pending actions related to certain of those items relevant to Idaho Power include the following:
• NOx: In 2010, the EPA adopted a new NAAQS for NOx at a level of 100 parts per billion averaged over a 1-hour
period. In connection with the new NAAQS, in February 2012 the EPA issued a final rule designating all of the
counties in Idaho, Nevada, Oregon, and Wyoming where Idaho Power owns or has an interest in a natural gas or coal-
fired power plant as “unclassifiable/attainment” for NOx. The EPA indicated it would review the designations after
2015, when three years of air quality monitoring data are available, and may formally designate the counties as
attainment or non-attainment for NOx. A designation of non-attainment may increase the likelihood that Idaho Power
would be required to install costly pollution control technology at one or more of its plants.
•
SO2: In 2010, the EPA adopted a new NAAQS for SO2 at a level of 75 parts per billion averaged over a one-hour
period. In 2011, the states of Idaho, Nevada, Oregon, and Wyoming sent letters to the EPA recommending that all
counties in these states be classified as "unclassifiable" under the new one-hour SO2 NAAQS because of a lack of
definitive monitoring and modeling data. In February 2013, the EPA issued letters to the states of Idaho and Oregon,
finding that the most recent air quality data for those states showed no violations of the 2010 SO2 standard. As a result,
the EPA is waiting to propose designation actions for those states, and is likely to proceed with designation actions
once additional data is gathered. Idaho Power expects that designations for Nevada and Wyoming will also be
addressed in a separate future action.
• Ozone: In late 2014, the EPA issued a proposed rule that would update the ozone standard under the CAA, from 75
parts per billion over an eight-hour period to 65 to 70 parts per billion over an eight-hour period. On October 1, 2015,
the EPA issued a final rule lowering the national ozone standard under the CAA to 70 parts per billion. The EPA stated
that the vast majority of U.S. counties will meet the standards by 2025 with federal and state rules and programs now
in place or underway. The EPA's plan provides for finalizing non-attainment designations in 2017, and it plans to
propose rules and guidance over the next year to help states with potential non-attainment areas implement the revised
standards. Non-attainment areas will have until 2020 to late 2037 to meet the new standard, with attainment dates
varying based on the ozone level in the area. Due to high levels of background ozone, which can be caused by factors
such as elevation, vegetation, wildfire, and international transport, attainment in areas within the Intermountain West
may be difficult, and the formulation of state implementation plans to bring an area into compliance with the new
standard may be challenging due to the existence of ozone caused by factors outside of local control. If the EPA were
to make non-attainment determinations in areas where Idaho Power owns or co-owns power plants, or proposes to
construct power plants, the state implementation plan for those areas could result in changes to the nature and
frequency of operation of existing generation plants and make more difficult or costly the construction of new power
generation plants. Idaho Power will seek to work with state regulators on implementation plans for any non-attainment
areas, in an effort to reduce the potential adverse impact on Idaho Power's operation of its existing power generation
plants and construction of future facilities.
Because the EPA has not yet completed the designation of areas as attaining or not attaining the NAAQS for NOx, SO2, and
ozone, Idaho Power is unable to predict what impact the adoption and implementation of these standards may have on its
operations, though it does expect at least some increases in capital and operating costs from the standards if areas in which
Idaho Power operate, or adjacent areas, receive non-attainment designations.
Regional Haze Rules: In accordance with federal regional haze rules under the CAA, coal-fired utility boilers are subject to
regional haze - best available retrofit technology (RH BART) if they were built between 1962 and 1977 and affect any "Class
I" (wilderness) areas. This includes all four units at the Jim Bridger and the Boardman coal-fired plants. The RH BART rules
would have required installation of a suite of emissions controls at the Boardman plant; however, in December 2010, the
Oregon Environmental Quality Commission approved a plan to install a less costly suite of environmental controls and cease
coal-fired operations at the Boardman power plant no later than December 31, 2020.
In December 2009, the Wyoming Department of Environmental Quality (WDEQ) issued a RH BART permit to PacifiCorp as
the operator of the Jim Bridger plant. As part of the WDEQ's long term strategy for regional haze, the permit required that
PacifiCorp install SCR equipment for NOx control at Jim Bridger units 3 and 4 by December 31, 2015 and December 31, 2016,
respectively, which has been completed, and submit an application by December 31, 2017 to install add-on NOx controls at Jim
Bridger unit 2 by 2021 and unit 1 by 2022, which was submitted in December 2017. In November 2010, PacifiCorp and the
69
WDEQ signed a settlement agreement under which PacifiCorp agreed to the timing and nature of the controls. The settlement
agreement was conditioned on the EPA ultimately approving those portions of the Wyoming regional haze SIP that are
consistent with the terms of the settlement agreement. In January 2014, the EPA approved Wyoming's regional haze SIP as to
the Jim Bridger plant, with the NOx control compliance dates set forth in the settlement agreement. Several interested parties
have appealed the EPA's decisions on Wyoming's regional haze SIP on various grounds. Idaho Power has not appealed the
EPA's decisions but has intervened in the proceedings to participate if and to the extent the Jim Bridger plant could be affected.
Clean Water Act Matters
Definition of “Waters of the United States” Under the CWA: On August 28, 2015, the EPA's and U.S. Army Corps of
Engineers' final rule defining the phrase "waters of the United States" under the CWA became effective (WOTUS Rule). Idaho
Power believes that the final rule potentially expanded federal jurisdiction under the CWA beyond traditional navigable waters,
interstate waters, territorial seas, tributaries, and adjacent wetlands, to a number of other waters, including waters with a
"significant nexus" to those traditional waters. The WOTUS Rule was widely challenged in both federal district and circuit
courts. The State of Idaho, and several other parties, challenged the rule in North Dakota federal court. That court held that it
had jurisdiction and enjoined the implementation of the WOTUS Rule. In February 2017, President Trump issued an executive
order directing the EPA and the U.S. Army Corps of Engineers to rescind the WOTUS Rule. In July 2017, the EPA and the U.S.
Army Corps of Engineers issued a notice of their intent to rescind and replace the definition of "waters of the United States"
under the CWA, which Idaho Power expects would reduce the number of waters in Idaho Power's service area subject to the
WOTUS Rule. In November 2017, the EPA issued a notice that it will delay the effectiveness of the WOTUS Rule until 2020
while the U.S. Army Corps of Engineers considers a replacement rule. On January 22, 2018, the U.S. Supreme Court issued a
unanimous ruling that challenges to the WOTUS Rule must begin with the federal district courts, effectively negating a
nationwide stay issued by the Sixth Circuit in 2016. However, because the State of Idaho remains a party to the federal court
action in North Dakota, that court’s enjoinder remains in effect, meaning the WOTUS Rule currently does not apply to actions
brought in Idaho.
Idaho Power has analyzed the WOTUS Rule and expects that, even if the WOTUS Rule is reinstated in Idaho, while it may
cause Idaho Power to incur additional permitting, regulatory requirements, and other costs associated with the rule, the
aggregate amount of increased costs is unlikely to have a material adverse effect on Idaho Power's operations or financial
condition, in part due to the relatively arid climate of Idaho Power's service area. Similarly, because the CWA, as interpreted
even prior to the WOTUS Rule, applies to most of Idaho Power's facilities, including its hydroelectric plants, Idaho Power does
not expect this proposal to have a material benefit to Idaho Power's operations or financial condition.
CWA Matters Related to Hydroelectric Relicensing: Idaho Power is also addressing CWA issues associated with the
relicensing of its HCC. See “Relicensing of Hydroelectric Projects” in this MD&A for additional information on the impact of
the CWA on that relicensing effort.
Review of Federal Coal Leases
In January 2016, the Secretary of the U.S. Department of the Interior issued an order directing the BLM to prepare a
Programmatic Environmental Impact Statement (PEIS) to analyze potential reforms to the federal coal lease program and
placed a moratorium on new federal coal leasing, with limited exceptions, pending completion of the PEIS. In January 2017,
the Secretary of the Department of the Interior ordered a cessation of all work on the PEIS and in March 2017 lifted the
moratorium on new federal coal leases. As of the date of this report, Idaho Power believes that BCC has adequate reserves
under existing leases to satisfy its coal delivery obligations to the Jim Bridger plant during the term of the existing coal supply
contract through 2024, and that the Jim Bridger plant will otherwise have access to sufficient coal supplies for its operation for
the foreseeable future. However, the lifting of the moratorium could increase the availability of coal resources and lower the
cost of leases for coal resources, which could reduce the fuel cost for each of Idaho Power's co-owned coal-fired plants.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES
When preparing financial statements in accordance with GAAP, IDACORP’s and Idaho Power’s management must apply
accounting policies and make estimates that affect the reported amounts of assets, liabilities, revenues, and expenses and related
disclosure of contingent assets and liabilities. These estimates often involve judgment about factors that are difficult to predict
and are beyond management’s control. Management adjusts these estimates based on historical experience and on other
assumptions and factors that are believed to be reasonable under the circumstances. Actual amounts could materially differ from
the estimates. Management believes the accounting policies and estimates discussed below are the most critical to the portrayal
of their financial condition and results of operations and require management’s most difficult, subjective, or complex
judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and may
change in subsequent periods.
Accounting for Rate Regulation
Entities that meet specific conditions are required by GAAP to reflect the impact of regulatory decisions in their consolidated
financial statements and to defer certain costs as regulatory assets until matching revenues can be recognized. Similarly, certain
items may be deferred as regulatory liabilities. Idaho Power must satisfy three conditions to apply regulatory accounting: (1) an
independent regulator must set rates; (2) the regulator must set the rates to cover specific costs of delivering service; and (3) the
service area must lack competitive pressures to reduce rates below the rates set by the regulator.
Idaho Power has determined that it meets these conditions, and its financial statements reflect the effects of the different rate-
making principles followed by the jurisdictions regulating Idaho Power. The primary effect of this policy is that Idaho Power
had recorded approximately $1.1 billion of regulatory assets and $0.7 billion of regulatory liabilities at December 31, 2017.
Idaho Power expects to recover these regulatory assets from customers through rates and refund these regulatory liabilities to
customers through rates, but recovery or refund is subject to final review by the regulatory bodies. If future recovery or refund
of these amounts ceases to be probable, or if Idaho Power determines that it no longer meets the criteria for applying regulatory
accounting, or if accounting rules change to no longer provide for regulatory assets and liabilities, Idaho Power could be
required to eliminate those regulatory assets or liabilities, which could have a material effect on Idaho Power’s financial
condition or results of operations.
Refer to Note 3 - “Regulatory Matters” to the consolidated financial statements included in this report for additional
information relating to regulatory matters.
Income Taxes
IDACORP and Idaho Power use judgment and estimation in developing the provision for income taxes and the reporting of tax-
related assets and liabilities. The interpretation of tax laws can involve uncertainty, since tax authorities may interpret such laws
differently. Actual income taxes could vary from estimated amounts and may result in favorable or unfavorable impacts to net
income, cash flows, and tax-related assets and liabilities.
Idaho Power provides deferred income taxes related to its plant assets for the difference between income tax depreciation and
book depreciation used for financial statement purposes. Deferred income taxes for other items are provided for the temporary
differences between the income tax and financial accounting treatment of such items. Unless contrary to applicable income tax
guidance, deferred income taxes are not provided for those income tax temporary differences where the prescribed regulatory
accounting methods, or flow-through, direct Idaho Power to recognize the tax impacts currently for rate making and financial
reporting.
Refer to Note 1 - “Summary of Significant Accounting Policies” and Note 2 - “Income Taxes” to the consolidated financial
statements included in this report for additional information relating to income taxes.
Pension and Other Postretirement Benefits
Idaho Power maintains a tax-qualified, noncontributory defined benefit pension plan covering most employees, an unfunded
nonqualified deferred compensation plan for certain senior management employees and directors called the Security Plan for
Senior Management Employees (SMSP), and a postretirement benefit plan (consisting of health care and death benefits).
The costs IDACORP and Idaho Power record for these plans depend on the provisions of the plans, changing employee
demographics, actual returns on plan assets, and several assumptions used in the actuarial valuations from which the expense is
71
derived. The key actuarial assumptions that affect expense are the expected long-term return on plan assets and the discount rate
used in determining future benefit obligations. Management evaluates the actuarial assumptions on an annual basis, taking into
account changes in market conditions, trends, and future expectations. Estimates of future stock market performance, changes
in interest rates, and other factors used to develop the actuarial assumptions are uncertain, and actual results could vary
significantly from the estimates.
The assumed discount rate is based on reviews of market yields on high-quality corporate debt. Specifically, IDACORP and
Idaho Power determined the discount rate for each plan through the construction of hypothetical portfolios of bonds selected
from high-quality corporate bonds available as of December 31, 2017, with maturities matching the projected cash outflows of
the plans. Based on the results of this analysis, the discount rate used to calculate the 2018 pension expense will be decreased to
3.95 percent from the 4.45 percent used in 2017.
Rate-of-return projections for plan assets are based on historical risk/return relationships among asset classes. The primary
measure is the historical risk premium each asset class has delivered versus the yield on the Moody's AA Corporate Bond
Index. This historical risk premium is then added to the current yield on the Moody's AA Corporate Bond Index, and Idaho
Power believes the result provides a reasonable prediction of future investment performance. Additional analysis is performed
to measure the expected range of returns, as well as worst-case and best-case scenarios. Based on the current interest rate
environment, current rate-of-return expectations are lower than the nominal returns generated over the past 20 years when
interest rates were generally much higher. The long-term rate of return used to calculate the 2018 pension expense will be 7.5
percent, the same assumption as was used for 2017.
Gross net periodic pension and other postretirement benefit cost for these plans totaled $50.4 million, $51.8 million, and $51.4
million for the years ended December 31, 2017, 2016, and 2015, respectively, including amounts deferred as regulatory assets
(see discussion below) and amounts allocated to capitalized labor. For 2018, gross pension and other postretirement benefit
costs are expected to total approximately $48 million, which takes into account the change in the discount rate noted above.
Had different actuarial assumptions been used, pension expense could have varied significantly. The following table reflects the
sensitivities associated with changes in the discount rate and rate-of-return on plan assets actuarial assumptions on historical
and future pension and postretirement expense:
Discount rate
Rate of return
2018
2017
2018
(millions of dollars)
2017
Effect of 0.5% rate increase on net periodic benefit cost
Effect of 0.5% rate decrease on net periodic benefit cost
$
(7.9) $
8.8
(7.2) $
7.9
(3.7) $
3.6
(3.2)
3.2
Additionally, a 0.5 percent increase in the plans' discount rates would have resulted in a $84.7 million decrease in the combined
benefit obligations of the plans as of December 31, 2017. A 0.5 percent decrease in the plans' discount rates would have resulted
in an $95.7 million increase in the combined benefit obligations of the plans as of December 31, 2017.
The IPUC has authorized Idaho Power to account for its defined benefit pension plan expense on a cash basis, and to defer and
account for accrued pension expense as a regulatory asset. The IPUC acknowledged that it is appropriate for Idaho Power to
seek recovery in its revenue requirement of reasonable and prudently incurred pension expense based on actual cash
contributions. In 2007, Idaho Power began deferring pension expense to a regulatory asset account to be matched with revenue
when future pension contributions are recovered through rates. At December 31, 2017, a total of $127.7 million of expense was
deferred as a regulatory asset. Approximately $20 million is expected to be deferred in 2018. Idaho Power recorded pension
expense of approximately $19 million in 2017, 2016, and 2015.
Refer to Note 11 – “Benefit Plans” to the consolidated financial statements included in this report for additional information
relating to pension and postretirement benefit plans.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
IDACORP and Idaho Power are exposed to market risks, including changes in interest rates, changes in commodity prices,
credit risk, and equity price risk. The following discussion summarizes these risks and the financial instruments, derivative
instruments, and derivative commodity instruments sensitive to changes in interest rates, commodity prices, and equity prices
that were held at December 31, 2017. IDACORP and Idaho Power have not entered into any of these market-risk-sensitive
instruments for trading purposes.
Interest Rate Risk
IDACORP and Idaho Power manage interest expense and short- and long-term liquidity through a combination of fixed rate
and variable rate debt. Generally, the amount of each type of debt is managed through market issuance, but interest rate swap
and cap agreements with highly-rated financial institutions may be used to achieve the desired combination.
Variable Rate Debt: As of December 31, 2017, IDACORP and Idaho Power had no net floating rate debt, as the carrying value
of short-term investments exceeded the carrying value of outstanding variable-rate debt.
Fixed Rate Debt: As of December 31, 2017, both IDACORP and Idaho Power had $1.7 billion in fixed rate debt, with a fair
market value of approximately $1.9 billion. These instruments are fixed rate and, therefore, do not expose the companies to a
loss in earnings due to changes in market interest rates. However, the fair value of these instruments would increase by
approximately $260 million if market interest rates were to decline by one percentage point from their December 31, 2017,
levels.
Commodity Price Risk
IDACORP's exposure to changes in commodity prices is related to Idaho Power's ongoing utility operations that produce
electricity to meet the demand of its retail electric customers. These effects of changes in commodity prices on Idaho Power are
mitigated in large part by Idaho Power's Idaho and Oregon power cost adjustment mechanisms. To supplement its generation
resources and balance its supply of power with the demand of its retail customers, Idaho Power participates in the wholesale
marketplace. These purchased power arrangements allow Idaho Power to respond to fluctuations in the demand for electricity
and variability in generating plant operations. Idaho Power also enters into arrangements for the purchase of fuel for natural gas
and coal-fired generating plants. These contracts for the purchase of power and fuel expose Idaho Power to commodity price
risk.
A number of factors associated with the structure and operation of the energy markets influence the level and volatility of prices
for energy commodities and related derivative products. The weather is a major uncontrollable factor affecting the local and
regional demand for electricity and the availability and cost of power generation. Other factors include the occurrence and
timing of demand peaks due to seasonal, daily, and hourly power demand; power supply; power transmission capacity; changes
in federal and state regulation and compliance obligations; fuel supplies; and market liquidity.
The primary objectives of Idaho Power’s energy purchase and sale activity are to meet the demand of retail electric customers,
to maintain appropriate physical reserves to ensure reliability, and to make economic use of temporary surpluses that may
develop. Idaho Power has adopted a risk management program, which has been reviewed and accepted by the IPUC, designed
to reduce exposure to power supply cost-related uncertainty, further mitigating commodity price risk. Idaho Power’s Energy
Risk Management Policy (Policy) and associated standards implementing the Policy describe a collaborative process with
customers and regulators via a committee called the Customer Advisory Group (CAG). The Risk Management Committee
(RMC), comprised of selected Idaho Power officers and other senior staff, oversees the risk management program. The RMC is
responsible for communicating the status of risk management activities to the Idaho Power Board of Directors and to the CAG,
and Idaho Power’s Audit Committee is responsible for approving the Policy and associated standards. The RMC is also
responsible for conducting an ongoing general assessment of the appropriateness of Idaho Power’s strategies for energy risk
management activities. In its risk management process, Idaho Power considers both demand-side and supply-side options
consistent with its IRP. The primary tools for risk mitigation are physical and financial forward power transactions and fueling
alternatives for utility-owned generation resources. Idaho Power only engages in a nominal amount of trading activity for non-
retail purposes.
The Policy requires monitoring monthly volumetric electricity position and total monthly dollar (net power supply cost)
exposure on a rolling 18-month forward view. The power supply business unit produces and evaluates projections of the
operating plan based on factors such as forecasted resource availability, stream flows, and load, and orders risk mitigating
73
actions, including resource optimization and hedging strategies, dictated by the limits stated in the Policy to bring exposures
within pre-established risk guidelines. The RMC evaluates the actions initiated by power supply for consistency and
compliance with the Policy. Idaho Power representatives meet with the CAG at least annually to assess effectiveness of the
limits. Changes to the limits can be endorsed by the CAG and referred to the board of directors for approval.
Credit Risk
IDACORP is subject to credit risk based on Idaho Power's activity with market counterparties. Idaho Power is exposed to this
risk to the extent that a counterparty may fail to fulfill a contractual obligation to provide energy, purchase energy, or complete
financial settlement for market activities. Idaho Power mitigates this exposure by actively establishing credit limits; measuring,
monitoring, and reporting credit risk using appropriate contractual arrangements; and transferring of credit risk through the use
of financial guarantees, cash, or letters of credit. Idaho Power maintains a current list of acceptable counterparties and credit
limits.
The use of performance assurance collateral in the form of cash, letters of credit, or guarantees is common industry practice.
Idaho Power maintains margin agreements relating to its wholesale commodity contracts that allow performance assurance
collateral to be requested of and/or posted with certain counterparties. As of December 31, 2017, Idaho Power had posted $0.9
million performance assurance collateral related to these contracts. Should Idaho Power experience a reduction in its credit
rating on Idaho Power’s unsecured debt to below investment grade, Idaho Power could be subject to requests by its wholesale
counterparties to post additional performance assurance collateral. Counterparties to derivative instruments and other forward
contracts could request immediate payment or demand immediate ongoing full daily collateralization on derivative instruments
and contracts in net liability positions. Based upon Idaho Power’s energy and fuel portfolio and market conditions as of
December 31, 2017, the amount of collateral that could be requested upon a downgrade to below investment grade was
approximately $5 million. To minimize capital requirements, Idaho Power actively monitors the portfolio exposure and the
potential exposure to additional requests for performance assurance collateral calls through sensitivity analysis.
Idaho Power is obligated to provide service to all electric customers within its service area. Credit risk for Idaho Power’s retail
customers is managed by credit and collection policies that are governed by rules issued by the IPUC or OPUC. Idaho Power
records a provision for uncollectible accounts, based upon historical experience, to provide for the potential loss from
nonpayment by these customers. Idaho Power continuously monitors levels of nonpayment from customers and makes any
necessary adjustments to its provision for uncollectible accounts accordingly.
Idaho utility customer relations rules prohibit Idaho Power from terminating electric service during the months of December
through February to any residential customer who declares that he or she is unable to pay in full for utility service and whose
household includes children, elderly, or infirm persons. Idaho Power’s provision for uncollectible accounts could be affected by
changes in future prices as well as changes in IPUC or OPUC regulations.
Equity Price Risk
IDACORP is exposed to price fluctuations in equity markets, primarily through Idaho Power's defined benefit pension plan
assets, a mine reclamation trust fund owned by an equity-method investment of Idaho Power, and other equity security
investments at Idaho Power. The equity securities held by the pension plan and in such accounts are diversified to achieve broad
market participation and reduce the impact of any single investment, sector, or geographic region. Idaho Power has established
asset allocation targets for the pension plan holdings, which are described in Note 11 - "Benefit Plans" to the consolidated
financial statements included in this report.

IDACORP, INC. AND IDAHO POWER COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
This Annual Report on Form 10-K is a combined report of IDACORP, Inc. (IDACORP) and Idaho Power Company (Idaho
Power). Therefore, these Notes to the Consolidated Financial Statements apply to both IDACORP and Idaho Power. However,
Idaho Power makes no representation as to the information relating to IDACORP’s other operations.
Nature of Business
IDACORP is a holding company formed in 1998 whose principal operating subsidiary is Idaho Power. Idaho Power is an
electric utility engaged in the generation, transmission, distribution, sales, and purchase of electric energy and capacity with a
service area covering approximately 24,000 square miles in southern Idaho and eastern Oregon. Idaho Power is regulated
primarily by the state utility regulatory commissions of Idaho and Oregon and the Federal Energy Regulatory Commission
(FERC). Idaho Power is the parent of Idaho Energy Resources Co. (IERCo), a joint venturer in Bridger Coal Company (BCC),
which mines and supplies coal to the Jim Bridger generating plant owned in part by Idaho Power.
IDACORP’s other significant wholly-owned subsidiaries include IDACORP Financial Services, Inc. (IFS), an investor in
affordable housing and other real estate investments, and Ida-West Energy Company (Ida-West), an operator of small
hydroelectric generation projects that satisfy the requirements of the Public Utility Regulatory Policies Act of 1978 (PURPA).
Principles of Consolidation
IDACORP’s and Idaho Power’s consolidated financial statements include the assets, liabilities, revenues and expenses of each
company and its wholly-owned subsidiaries listed above, as well as any variable interest entities (VIEs) for which the
respective company is the primary beneficiary. Investments in VIEs for which the companies are not the primary beneficiaries,
but have the ability to exercise significant influence over operating and financial policies, are accounted for using the equity
method of accounting.
IDACORP also consolidates one variable interest entity (VIE), Marysville Hydro Partners (Marysville), which is a joint venture
owned 50 percent by Ida-West and 50 percent by Environmental Energy Company (EEC). At December 31, 2017, Marysville
had approximately $18 million of assets, primarily a hydroelectric plant, and approximately $9 million of intercompany long-
term debt, which is eliminated in consolidation. EEC has borrowed amounts from Ida-West to fund a portion of its required
capital contributions to Marysville. The loans are payable from EEC’s share of distributions from Marysville and are secured by
the stock of EEC and EEC’s interest in Marysville. Ida-West is identified as the primary beneficiary because the combination of
its ownership interest in the joint venture with the intercompany note and the EEC note result in Ida-West's ability to control the
activities of the joint venture. Creditors of Marysville have no recourse to the general credit of IDACORP and there are no other
arrangements that could require IDACORP to provide financial support to Marysville or expose IDACORP to losses.
The BCC joint venture is also a VIE, but because the power to direct the activities that most significantly impact the economic
performance of BCC is shared with the joint venture partner, Idaho Power is not the primary beneficiary. The carrying value of
BCC was $68.6 million at December 31, 2017, and Idaho Power's maximum exposure to loss is the carrying value, any
additional future contributions to BCC, and a $56.7 million guarantee for mine reclamation costs, which is discussed further in
Note 9 - "Commitments."
IFS's affordable housing limited partnership and other real estate investments are also VIEs for which IDACORP is not the
primary beneficiary. IFS's limited partnership interests range from 2 to 99 percent and were acquired between 1996 and 2010.
As a limited partner, IFS does not control these entities and they are not consolidated. IFS’s maximum exposure to loss in these
developments is limited to its net carrying value, which was $5.5 million at December 31, 2017.
Ida-West's other investments in PURPA facilities, BCC, and IFS's investments are accounted for under the equity method of
accounting (see Note 14 - "Investments").
Except for amounts related to sales of electricity by Ida-West's PURPA projects to Idaho Power, all intercompany transactions
and balances have been eliminated in consolidation.
88
The accompanying consolidated financial statements include Idaho Power's proportionate share of utility plant and related
operations resulting from its interests in jointly owned plants (see Note 12 - "Property, Plant and Equipment").
Regulation of Utility Operations
As a regulated utility, many of Idaho Power's fundamental business decisions are subject to the approval of governmental
agencies, including the prices that Idaho Power is authorized to charge for its electric service. These approvals are a critical
factor in determining IDACORP's and Idaho Power's results of operations and financial condition.
IDACORP’s and Idaho Power’s financial statements reflect the effects of the different ratemaking principles followed by the
jurisdictions regulating Idaho Power. The application of accounting principles related to regulated operations sometimes results
in Idaho Power recording expenses and revenues in a different period than when an unregulated enterprise would record such
expenses and revenues. In these instances, the amounts are deferred or accrued as regulatory assets or regulatory liabilities on
the balance sheet and recorded on the income statement when recovered or returned in rates. Additionally, regulators can
impose regulatory liabilities upon a regulated company for amounts previously collected from customers that are expected to be
refunded. The effects of applying these regulatory accounting principles to Idaho Power’s operations are discussed in more
detail in Note 3 - "Regulatory Matters."
Management Estimates
Management makes estimates and assumptions when preparing financial statements in conformity with generally accepted
accounting principles. These estimates and assumptions include those related to rate regulation, retirement benefits,
contingencies, asset impairment, income taxes, unbilled revenues, and bad debt. These estimates and assumptions affect the
reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reporting period. These estimates involve judgments
with respect to, among other things, future economic factors that are difficult to predict and are beyond management’s
control. Accordingly, actual results could differ from those estimates.
System of Accounts
The accounting records of Idaho Power conform to the Uniform System of Accounts prescribed by the FERC and adopted by
the public utility commissions of Idaho, Oregon, and Wyoming.
Cash and Cash Equivalents
Cash and cash equivalents include cash on-hand and highly liquid temporary investments that mature within 90 days of the date
of acquisition.
Receivables and Allowance for Uncollectible Accounts
Customer receivables are recorded at the invoiced amounts and do not bear interest. A late payment fee of one percent may be
assessed on account balances after 30 days. An allowance is recorded for potential uncollectible accounts. The allowance is
reviewed periodically and adjusted based upon a combination of historical write-off experience, aging of accounts receivable,
and an analysis of specific customer accounts. Adjustments are charged to income. Customer accounts receivable balances that
remain outstanding after reasonable collection efforts are written off.
Other receivables, primarily notes receivable from business transactions, are also reviewed for impairment periodically, based
upon transaction-specific facts. When it is probable that IDACORP or Idaho Power will be unable to collect all amounts due
according to the contractual terms of the agreement, an allowance is established for the estimated uncollectible portion of the
receivable and charged to income.
There were no impaired receivables without related allowances at December 31, 2017 and 2016. Once a receivable is
determined to be impaired, any further interest income recognized is fully reserved.
89
Derivative Financial Instruments
Financial instruments such as commodity futures, forwards, options, and swaps are used to manage exposure to commodity
price risk in the electricity and natural gas markets. All derivative instruments are recognized as either assets or liabilities at fair
value on the balance sheet unless they are designated as normal purchases and normal sales. With the exception of forward
contracts for the purchase of natural gas for use at Idaho Power's natural gas generation facilities and a nominal number of
power transactions, Idaho Power’s physical forward contracts are designated as normal purchases and normal sales. Because of
Idaho Power’s regulatory accounting mechanisms, Idaho Power records the changes in fair value of derivative instruments
related to power supply as regulatory assets or liabilities.
Revenues
Operating revenues related to Idaho Power’s sale of energy are recorded when service is rendered or energy is delivered to
customers. Idaho Power accrues estimated unbilled revenues for electric services delivered to customers but not yet billed at
year-end. Idaho Power does not report any collections of franchise fees and similar taxes related to energy consumption on the
income statement. In addition, regulatory mechanisms in place in Idaho and Oregon affect the reported amount of revenue. See
Note 3 - "Regulatory Matters" for additional discussion of certain of the following mechanisms:
•
•
•
•
energy efficiency riders to fund energy efficiency program expenditures. Expenditures funded through the riders are
reported as an operating expense with an equal amount of revenues recorded in other revenues;
a fixed cost adjustment mechanism that results in recording additional or reduced revenue based on the allowed and
actual fixed costs recovered through current rates;
a sharing mechanism providing for refunds to customers for earnings above stated returns on equity in Idaho; and
collection in base rates of a portion of the allowance for funds used during construction (AFUDC) related to its Hells
Canyon Complex (HCC) relicensing project. Cash collected under this ratemaking mechanism is not recorded as
revenue but is instead deferred as a regulatory liability.
Property, Plant and Equipment and Depreciation
The cost of utility plant in service represents the original cost of contracted services, direct labor and material, AFUDC, and
indirect charges for engineering, supervision, and similar overhead items. Repair and maintenance costs associated with
planned major maintenance are expensed as the costs are incurred, as are maintenance and repairs of property and replacements
and renewals of items determined to be less than units of property. For utility property replaced or renewed, the original cost
plus removal cost less salvage is charged to accumulated provision for depreciation, while the cost of related replacements and
renewals is added to property, plant and equipment.
All utility plant in service is depreciated using the straight-line method at rates approved by regulatory authorities. Annual
depreciation provisions as a percent of average depreciable utility plant in service approximated 2.9 percent in 2017, 2.6 percent
in 2016, and 2.7 percent in 2015.
During the period of construction, costs expected to be included in the final value of the constructed asset, and depreciated once
the asset is complete and placed in service, are classified as construction work in progress on the consolidated balance sheets. If
the project becomes probable of being abandoned, such costs are expensed in the period such determination is made. Idaho
Power may seek recovery of such costs in customer rates, although there can be no guarantee such recovery would be granted.
Long-lived assets are periodically reviewed for impairment when events or changes in circumstances indicate that the carrying
amount of an asset may not be recoverable. If the sum of the undiscounted expected future cash flows from an asset is less than
the carrying value of the asset, impairment is recognized in the financial statements. There were no material impairments of
long-lived assets in 2017, 2016, or 2015.
Allowance for Funds Used During Construction
AFUDC represents the cost of financing construction projects with borrowed funds and equity funds. With one exception, as
discussed above for the HCC relicensing project, cash is not realized currently from such allowance; it is realized under the
ratemaking process over the service life of the related property through increased revenues resulting from a higher rate base and
higher depreciation expense. The component of AFUDC attributable to borrowed funds is included as a reduction to total
interest expense. Idaho Power’s weighted-average monthly AFUDC rate was 7.6 percent for 2017, 2016 and 2015.
90
Income Taxes
IDACORP and Idaho Power account for income taxes under the asset and liability method, which requires the recognition of
deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial
statements. Under this method (commonly referred to as normalized accounting), deferred tax assets and liabilities are
determined based on the differences between the financial statements and tax basis of assets and liabilities using enacted tax
rates in effect for the year in which the differences are expected to reverse. In general, deferred income tax expense or benefit
for a reporting period is recognized as the change in deferred tax assets and liabilities from the beginning to the end of the
period. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that
includes the enactment date unless Idaho Power's primary regulator, the Idaho Public Utilities Commission (IPUC), orders
direct deferral of the effect of the change in tax rates over a longer period of time.
Consistent with orders and directives of the IPUC, unless contrary to applicable income tax guidance, Idaho Power does not
provide deferred income taxes for certain income tax temporary differences and instead recognizes the tax impact currently
(commonly referred to as flow-through accounting) for rate making and financial reporting. Therefore, Idaho Power's effective
income tax rate is impacted as these differences arise and reverse. Regulated enterprises are required to recognize such
adjustments as regulatory assets or liabilities if it is probable that such amounts will be recovered from or returned to customers
in future rates.
In compliance with the federal income tax requirements for the use of accelerated tax depreciation, Idaho Power provides
deferred income taxes related to its plant assets for the difference between income tax depreciation and book depreciation used
for financial statement purposes. Deferred income taxes are provided for other temporary differences unless accounted for using
flow-through.
The state of Idaho allows a three percent investment tax credit on qualifying plant additions. Investment tax credits earned on
regulated assets are deferred and amortized to income over the estimated service lives of the related properties. Credits earned
on non-regulated assets or investments are recognized in the year earned.
Income taxes are discussed in more detail in Note 2 - "Income Taxes."
Other Accounting Policies
Debt discount, expense, and premium are deferred and amortized over the terms of the respective debt issues. Losses on
reacquired debt and associated costs are amortized over the life of the associated replacement debt, as allowed under regulatory
accounting.
Supplemental Cash Flows Information
In 2015, Idaho Power executed an agreement to exchange property with another electric utility. Under the terms of the
agreement, each party transferred to the other transmission-related equipment with a book value of approximately $44 million.
Idaho Power received an immaterial amount of cash, representing the difference in the book value of the assets exchanged. Also
in 2015, Idaho Power executed a long-term service agreement and transferred to the service provider approximately $22 million
of spare parts in partial exchange for future services. No cash was exchanged in the 2015 transfer transaction.
Reclassifications
In these consolidated financial statements, certain amounts in prior periods’ consolidated financial statements have been
reclassified to conform with current period presentation. On both IDACORP's and Idaho Power's 2016 consolidated balance
sheets, the $9.5 million of American Falls and Milner water rights which had previously been reported separately was
reclassified to "Other" within Other Assets and Deferred Debits, respectively. Also, on Idaho Power's 2016 consolidated balance
sheet, $19.7 million was reclassified from "Other" in other assets to the newly created "Long-term receivables" within Deferred
Debits.
91
New and Recently Adopted Accounting Pronouncements
Recently Adopted Accounting Pronouncements
In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-02,
Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated
Other Comprehensive Income, which permits a reclassification from Accumulated Other Comprehensive Income (AOCI) to
retained earnings for the stranded tax effects resulting from the decrease in corporate tax rate from the enactment in December
2017 of a tax reform act, generally referred to as the “Tax Cuts and Jobs Act.” For more information on other impacts of the Tax
Cuts and Jobs Act, see Note 2 - "Income Taxes." As permitted by the FASB, IDACORP and Idaho Power elected to early adopt
the provisions of the new standard at December 31, 2017, resulting in a $4.1 million cumulative effect adjustment for a change
in accounting principle to both AOCI and retained earnings. The amount relates to stranded tax effects in AOCI resulting from
the Tax Cuts and Jobs Act related to annual valuation adjustments for two nonqualified defined benefit pension plans.
Recent Accounting Pronouncements Not Yet Adopted
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 is intended to
enable users of financial statements to better understand and consistently analyze an entity's revenue across industries,
transactions, and geographies. Under the ASU, recognition of revenue occurs when a customer obtains control of promised
goods or services. In addition, the ASU requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash
flows arising from contracts with customers. The FASB amended certain aspects of ASU 2014-09 to clarify the implementation
guidance, including clarifications related to principal versus agent considerations, licensing and identifying performance
obligations, narrow scope improvements, and practical expedients. The companies have assessed the impacts of ASU 2014-09
on their financial statements and have concluded the new guidance will not affect the timing and amount of revenue recognized.
However, the presentation and disclosure requirements of the standard will result in a change in the presentation of revenue on
the companies' consolidated statements of income as well as expanded disclosures around the disaggregation of revenue,
performance obligations, and transaction price. The guidance in ASU 2014-09 is effective for interim and annual reporting
periods beginning after December 15, 2017. The guidance permits two implementation approaches, one requiring retrospective
application of the new standard with restatement of prior years (full retrospective approach) and the other requiring prospective
application of the new standard including a cumulative-effect adjustment with disclosure of results under previous standards
(modified-retrospective approach). IDACORP and Idaho Power will adopt ASU 2014-09 on January 1, 2018, using the
modified-retrospective approach. As the standard does not change the timing and amount of revenue recognized for the
companies, no cumulative-effect adjustment is required.
In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and
Measurement of Financial Assets and Financial Liabilities, which revises the accounting related to the classification and
measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities
measured at fair value. It also amends certain disclosure requirements associated with the fair value of financial instruments.
The new standard is effective for fiscal years beginning after December 15, 2017, including interim periods. IDACORP and
Idaho Power concluded the adoption will not have a material impact on their financial statements.
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), intended to improve financial reporting about leasing
transactions. The ASU significantly changes the accounting model used by lessees to account for leases, requiring that all
material leases be presented on the balance sheet. Under the current model, some leases are classified as capital leases and
recorded on the balance sheet while other leases classified as operating leases are not recognized on the balance sheet. The new
standard is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption
permitted. The standard must be adopted using a modified-retrospective approach. IDACORP and Idaho Power are evaluating
the impact of ASU 2016-02 on their financial statements. Specifically, the companies are considering whether the new guidance
will affect their accounting for purchase power agreements, easements and rights-of-way, utility pole attachments, and other
utility industry-related arrangements. At this time, the companies do not know, and cannot reasonably estimate, the dollar
impact of the adoption.
92
In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), which amends ASC 230 to clarify
guidance on the classification of certain cash receipts and payments in the statement of cash flows. The FASB issued the ASU
with the intent of reducing diversity in practice with respect to eight types of cash flows. The companies expect the ASU to
affect the classification of proceeds from the settlement of corporate-owned life insurance policies and related costs, which will
be classified as investing activities under the new guidance. The companies already present debt prepayment and
extinguishment costs, proceeds from the settlement of insurance claims (other than corporate-owned life insurance), and
distributions received from equity-method investments in accordance with the new guidance. ASU 2016-15 is effective for
interim and annual reporting periods beginning after December 15, 2017. The standard must be adopted retrospectively to all
periods presented, unless impracticable to do so. IDACORP and Idaho Power do not believe the adoption will have a material
impact on their financial statements.
In March 2017, the FASB issued ASU 2017-07, Compensation -- Retirement Benefits (Topic 715): Improving the Presentation
of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which requires employers to disaggregate the
service cost component from other components of net periodic benefit costs and to disclose the amounts of net periodic benefit
costs that are included in each income statement line item. The standard requires employers to present the service cost
component in the same line item as other compensation costs and to present the other components of net periodic benefit costs
(which include interest costs, expected return on plan assets, amortization of prior service cost or credits and actuarial gains and
losses) separately and outside a subtotal of operating income. In addition, only the service cost component is eligible for
capitalization. Idaho Power currently capitalizes amounts of pension or postretirement costs that are insignificant to the
consolidated financial statements. The amendments in ASU 2017-07 are effective for interim and annual reporting periods
beginning after December 15, 2017. Entities must use (1) a retrospective transition method to adopt the requirement for
separate presentation in the income statement of service costs and other components and (2) a prospective transition method to
adopt the requirement to limit the capitalization of benefit costs to the service cost component. While ASU 2017-07 will result
in changes to the classification of the other components of net periodic benefit costs on the consolidated statements of income
of IDACORP and Idaho Power, the new standard will not materially affect the consolidated financial statements of the
companies.

IDACORP's tax allocation agreement provides that each member of its consolidated group compute its income taxes on a
separate company basis. Amounts payable or refundable are settled through IDACORP and are reported as taxes accrued or
income taxes receivable, respectively, on the consolidated balance sheets of Idaho Power. See Note 1 - "Summary of Significant
Accounting Policies" for further discussion of accounting policies related to income taxes.
Tax Credit Carryforwards
As of December 31, 2017, IDACORP had $72.0 million of general business credit carryforwards for federal income tax
purposes and $37.7 million of Idaho investment tax credit carryforward. The general business credit carryforward period
expires from 2026 to 2037, and the Idaho investment tax credit expires from 2022 to 2031.
94
Uncertain Tax Positions
IDACORP and Idaho Power believe that they have no material income tax uncertainties for 2017 and prior tax years. Both
companies recognize interest accrued related to unrecognized tax benefits as interest expense and penalties as other expense.
IDACORP and Idaho Power are subject to examination by their major tax jurisdictions - U.S. federal and the State of Idaho.
The open tax years for examination are 2017 for federal and 2013-2017 for Idaho. In May 2009, IDACORP formally entered
the U.S. Internal Revenue Service (IRS) Compliance Assurance Process (CAP) program for its 2009 tax year and has remained
in the CAP program for all subsequent years. The CAP program provides for IRS examination and issue resolution throughout
the current year with the objective of return filings containing no contested items. In 2017, the IRS completed its examination
of IDACORP's 2016 tax year with no unresolved income tax issues.
Tax Cuts and Jobs Act
On December 22, 2017, the Tax Cuts and Jobs Act was signed into law, which significantly reforms the Internal Revenue Code
of 1986, as amended. Effective January 1, 2018, the Tax Cuts and Jobs Act permanently lowers the corporate tax rate to 21
percent from the existing maximum rate of 35 percent, provides for expanded bonus depreciation, limits the deductibility of
interest expense, eliminates alternative minimum tax, repeals the manufacturing deduction, and imposes additional limitations
on the deductibility of executive compensation. Public utility companies, such as Idaho Power, retain the full deductibility of
interest expense and are excluded from the bonus depreciation provisions; however, traditional accelerated tax depreciation
methods are still available.
Due to the enactment of the Tax Cuts and Jobs Act and following generally accepted accounting principles, at December 31,
2017, IDACORP and Idaho Power remeasured all deferred income tax assets and liabilities. The effects of these adjustments
resulted in a net tax expense as shown in the rate reconciliation table above. Additionally, as shown in the deferred income tax
table above, the net deferred tax liabilities at both companies decreased significantly. Idaho Power's regulatory asset deferred
income tax liability item decreased as the related regulatory asset was reduced in two primary ways: 1) the decrease in the
federal income tax rate decreased the future cost to customers for funding the net deferred income tax liabilities resulting from
the cumulative impacts of using the flow-through income tax accounting method for regulatory purposes and 2) the decrease in
the federal income tax rate also reduced the net-to-gross multiplier that increases the regulatory asset to a revenue requirement
carrying value. The change in income tax law also reduced the deferred income tax liability for depreciation-related timing
differences under the normalized tax accounting method. As this reduction will flow back to customers in the future under the
statutorily prescribed average rate assumption method, it was recorded as a regulatory liability on the consolidated balance
sheets of the companies. See Note 3 - "Regulatory Matters" for more information.
The 2017 consolidated financial statements reflect the implementation of federal income tax reform as enacted and current
regulatory policies. Additional adjustments may be required in future periods based upon technical corrections to the federal
law, changes to state income tax policies, additional technical guidance from tax authorities, or orders from Idaho Power's
regulators.
3. REGULATORY MATTERS
IDACORP’s and Idaho Power’s financial statements reflect the effects of the different ratemaking principles followed by the
jurisdictions regulating Idaho Power. Included below is a summary of Idaho Power's regulatory assets and liabilities, as well as
a discussion of notable regulatory matters.
Regulatory Assets and Liabilities
The application of accounting principles related to regulated operations sometimes results in Idaho Power recording some
expenses and revenues in a different period than when an unregulated enterprise would record such expenses and revenues.
Regulatory assets represent incurred costs that have been deferred because it is probable they will be recovered from customers
through future rates. Regulatory liabilities represent obligations to make refunds to customers for previous collections, or
represent amounts collected in advance of incurring an expense.

(1) Earning a return includes either interest or a return on the investment as a component of rate base at the allowed rate of return.
(2) Represents flow-through income tax accounting differences which have a corresponding deferred tax liability disclosed in Note 2 - "Income Taxes." The Tax
Cuts and Jobs Act, enacted on December 22, 2017, reduced the deferred income tax assets and liabilities. For timing differences under the flow-through
income tax accounting method, this reduction also reduces the associated regulatory assets generally recoverable over the remaining lives of the associated
depreciable property.
(3) Represents the unfunded obligation of Idaho Power’s pension and postretirement benefit plans, which are discussed in Note 11 - "Benefit Plans."
(4) The energy efficiency asset represents the Oregon jurisdiction balance and the liability represents the Idaho jurisdiction balance.
(5) This item is discussed in more detail in this Note 3 - "Regulatory Matters."
(6) Asset retirement obligations and removal costs are discussed in Note 13 - "Asset Retirement Obligations."
(7) Represents the tax gross-up related to the depreciation-related excess deferred income taxes and investment tax credits included in this table and has a
corresponding deferred tax asset disclosed in Note 2 - "Income Taxes."
(8) The Tax Cuts and Jobs Act, enacted on December 22, 2017, reduced the deferred income tax assets and liabilities. For depreciation-related timing differences
under the normalized tax accounting method, this reduction will flow back to customers under the statutorily prescribed average rate assumption method.
(9) Idaho Power is collecting revenue in the Idaho jurisdiction for AFUDC on HCC relicensing costs but is deferring revenue recognition of the amounts
collected until the license is issued and the asset is placed in service under the new license.
(10) Mark-to-market assets and liabilities are discussed in Note 16 - "Fair Value Measurements."
Idaho Power’s regulatory assets and liabilities are typically amortized over the period in which they are reflected in customer
rates. In the event that recovery of Idaho Power’s costs through rates becomes unlikely or uncertain, regulatory accounting
would no longer apply to some or all of Idaho Power’s operations and the items above may represent stranded investments. If
not allowed full recovery of these items, Idaho Power would be required to write off the applicable portion, which could have a
materially adverse financial impact.
96
Power Cost Adjustment Mechanisms and Deferred Power Supply Costs
In both its Idaho and Oregon jurisdictions, Idaho Power's power cost adjustment mechanisms address the volatility of power
supply costs and provide for annual adjustments to the rates charged to its retail customers. The power cost adjustment
mechanisms compare Idaho Power's actual net power supply costs (primarily fuel and purchased power less off-system sales)
against net power supply costs being recovered in Idaho Power's retail rates. Under the power cost adjustment mechanisms,
certain differences between actual net power supply costs incurred by Idaho Power and costs being recovered in retail rates are
recorded as a deferred charge or credit on the balance sheets for future recovery or refund. The power supply costs deferred
primarily result from changes in contracted power purchase prices and volumes, changes in wholesale market prices and
transaction volumes, fuel prices, and the levels of Idaho Power's own generation. The Idaho deferral period or PCA year runs
from April 1 through March 31. Amounts deferred during the PCA year are primarily recovered or refunded during the
subsequent June 1 through May 31 period.
Idaho Jurisdiction Power Cost Adjustment Mechanism: In the Idaho jurisdiction, the annual PCA adjustment consists of (a) a
forecast component, based on a forecast of net power supply costs in the coming year as compared with net power supply costs
included in base rates; and (b) a true-up component, based on the difference between the previous year’s actual net power
supply costs and the previous year’s forecast. The latter component also includes a balancing mechanism so that, over time, the
actual collection or refund of authorized true-up dollars matches the amounts authorized. The PCA mechanism also includes:
•
•
a cost or benefit sharing ratio that allocates the deviations in net power supply expenses between customers (95
percent) and shareholders (5 percent), with the exceptions of expenses associated with PURPA power purchases and
demand response incentive payments, which are allocated 100 percent to customers; and
a sales-based adjustment intended to ensure that power supply expense recovery resulting solely from sales changes
does not distort the results of the mechanism.
The table below summarizes the three most recent PCA rate adjustments, all of which also include non-PCA-related rate
adjustments as ordered by the IPUC:
Effective
Date
June 1, 2017
$ Change
(millions) Notes
$
10.6 The net increase in PCA rates included an offsetting $13.0 million reduction for the refund of
previously collected Idaho energy efficiency rider funds.
June 1, 2016
$
17.3 The net increase in PCA rates included the application of (a) a customer rate credit of $3.2
million for sharing of revenues with customers for the year 2015 under the terms of the
October 2014 settlement stipulation, and (b) $4.0 million of surplus Idaho energy efficiency
rider funds.
June 1, 2015
$
(11.6) The net decrease in PCA rates included the application of (a) a customer rate credit of $8.0
million for sharing of revenues with customers for the year 2014 under the terms of the
December 2011 settlement stipulation, (b) a $1.5 million customer benefit relating to a
change to the PCA methodology in 2015, and (c) $4.0 million of surplus Idaho energy
efficiency rider funds.
In March 2014, the IPUC issued an order approving Idaho Power's application requesting an increase of approximately $106
million in the normalized or "base level" net power supply expense on a total-system basis to be used to update base rates and
in the determination of the PCA rate that became effective June 1, 2014. Approval of the order removed the Idaho-jurisdictional
portion of those expenses (approximately $99 million) from collection via the PCA mechanism and instead results in collecting
that portion through base rates.
Oregon Jurisdiction Power Cost Adjustment Mechanism: Idaho Power’s power cost recovery mechanism in Oregon has two
components: an annual power cost update (APCU) and a power cost adjustment mechanism (PCAM). The APCU allows Idaho
Power to reestablish its Oregon base net power supply costs annually, separate from a general rate case, and to forecast net
power supply costs for the upcoming water year. The PCAM is a true-up filed annually in February. The filing calculates the
deviation between actual net power supply expenses incurred for the preceding calendar year and the net power supply
expenses recovered through the APCU for the same period. Under the PCAM, Idaho Power is subject to a portion of the
business risk or benefit associated with this deviation through application of an asymmetrical deadband (or range of deviations)
within which Idaho Power absorbs cost increases or decreases. For deviations in actual power supply costs outside of the
deadband, the PCAM provides for 90/10 sharing of costs and benefits between customers and Idaho Power. However,
collection by Idaho Power will occur only to the extent that Idaho Power’s actual Oregon-jurisdictional return on equity
(Oregon ROE) for the year is at least 100 basis points below Idaho Power’s last authorized Oregon ROE. A refund to customers
will occur only to the extent that Idaho Power’s actual Oregon ROE for that year is at least 100 basis points above Idaho
97
Power’s last authorized Oregon ROE. Oregon jurisdiction power supply cost changes under the APCU and PCAM during each
of 2017, 2016, and 2015 are summarized in the table that follows:
Year and
Mechanism APCU or PCAM Adjustment
2017 PCAM Actual net power supply costs were within the deadband, resulting in no deferral.
2017 APCU
A rate increase of $0.7 million annually took effect June 1, 2017.
2016 PCAM Actual net power supply costs were within the deadband, resulting in no deferral.
2016 APCU
A rate increase of $0.2 million annually took effect June 1, 2016.
2015 PCAM Actual net power supply costs were within the deadband, resulting in no deferral.
A rate decrease of $0.7 million annually took effect June 1, 2015.
2015 APCU
Notable Idaho Regulatory Matters
Idaho Base Rate Changes: Idaho base rates were most recently established in 2012, and adjusted in 2014. Effective January 1,
2012, Idaho Power implemented new Idaho base rates resulting from IPUC approval of a settlement stipulation that provided
for a 7.86 percent authorized overall rate of return on an Idaho-jurisdiction rate base of approximately $2.36 billion. The
settlement stipulation resulted in a 4.07 percent, or $34.0 million, overall increase in Idaho Power's annual Idaho-jurisdiction
base rate revenues. Idaho base rates were subsequently adjusted again in 2012, in connection with Idaho Power's completion of
the Langley Gulch power plant. In June 2012, the IPUC issued an order approving a $58.1 million increase in annual Idaho-
jurisdiction base rates, effective July 1, 2012. The order also provided for a $335.9 million increase in Idaho rate base. Neither
the settlement stipulation nor the IPUC orders adjusting base rates specified an authorized rate of return on equity or imposed a
moratorium on Idaho Power filing a general rate case at a future date.
As noted above in this Note 3, the IPUC also issued a March 2014 order approving Idaho Power's request for an increase in the
normalized or "base level" net power supply expense to be used to update base rates and in the determination of the PCA rate
that became effective June 1, 2014.
October 2014 Idaho Settlement Stipulation: In October 2014, the IPUC issued an order approving an extension, with
modifications, of the terms of a December 2011 Idaho settlement stipulation for the period from 2015 through 2019, or until the
terms are otherwise modified or terminated by order of the IPUC or the full $45 million of additional accumulated deferred
investment tax credits (ADITC) contemplated by the settlement stipulation has been amortized. The provisions of the October
2014 settlement stipulation are as follows:
•
•
•
•
•
If Idaho Power's actual annual Idaho-jurisdiction return on year-end equity (Idaho ROE) in any year is less than 9.5
percent, then Idaho Power may amortize up to $25 million of additional ADITC to help achieve a 9.5 percent Idaho
ROE for that year, and may amortize up to a total of $45 million of additional ADITC over the 2015 through 2019
period.
If Idaho Power's annual Idaho ROE in any year exceeds 10.0 percent, the amount of earnings exceeding a 10.0
percent Idaho ROE and up to and including a 10.5 percent Idaho ROE will be allocated 75 percent to Idaho Power's
Idaho customers as a rate reduction to be effective at the time of the subsequent year's PCA and 25 percent to Idaho
Power.
If Idaho Power's annual Idaho ROE in any year exceeds 10.5 percent, the amount of earnings exceeding a 10.5
percent Idaho ROE will be allocated 50 percent to Idaho Power's Idaho customers as a rate reduction to be effective at
the time of the subsequent year's PCA, 25 percent to Idaho Power's Idaho customers in the form of a reduction to the
pension expense deferral regulatory asset (to reduce the amount to be collected in the future from Idaho customers),
and 25 percent to Idaho Power.
If the full $45 million of additional ADITC contemplated by the settlement stipulation has been amortized the sharing
provisions would terminate.
In the event the IPUC approves a change to Idaho Power's Idaho-jurisdictional allowed return on equity as part of a
general rate case proceeding seeking a rate change effective prior to January 1, 2020, the Idaho ROE thresholds (9.5
percent, 10.0 percent, and 10.5 percent) will be adjusted prospectively.
Neither the settlement stipulation nor the associated IPUC order impose a moratorium on Idaho Power filing a general rate case
or other form of rate proceeding during the term of the settlement stipulation.
98
In 2015, Idaho Power recorded a $3.2 million provision against current revenue for sharing with customers, as its Idaho ROE
for 2015 was above 10.0 percent. In both 2016 and 2017, Idaho Power recorded no additional ADITC amortization and no
provision for sharing with customers, as its Idaho ROE in both years was between 9.5 percent and 10.0 percent. Accordingly, at
December 31, 2017, the full $45 million of additional ADITC remains available for future use under the terms of the settlement
stipulation.
Fixed Cost Adjustment: The Idaho jurisdiction fixed cost adjustment (FCA) mechanism is designed to remove Idaho Power’s
financial disincentive to invest in energy efficiency programs by separating (or decoupling) the recovery of fixed costs from the
variable kilowatt-hour charge and linking it instead to a set amount per customer. The FCA mechanism is adjusted each year to
collect, or refund, the difference between the authorized fixed-cost recovery amount and the actual fixed costs recovered by
Idaho Power during the year. The annual change in the FCA recovery is capped at no more than 3 percent of base revenue, with
any excess deferred for collection in a subsequent year.
The following table summarizes FCA amounts approved for collection in the prior three FCA years:

In July 2014, the IPUC opened a docket to allow Idaho Power, the IPUC Staff, and other interested parties to further evaluate
the IPUC Staff's concerns regarding the application of the FCA mechanism (including weather-normalization, customer count
methodology, rate adjustment cap, and cross-subsidization issues) and whether the FCA is effectively removing Idaho Power's
disincentive to aggressively pursue energy efficiency programs. In May 2015, the IPUC approved a settlement stipulation that
modified the FCA mechanism by replacing weather-normalized billed sales with actual billed sales in the calculation of the
FCA, applicable for the entirety of calendar year 2015 and thereafter, and reflected in FCA rates effective June 1, 2016.
Hells Canyon Complex Relicensing Costs Settlement Stipulation: In December 2016, Idaho Power filed an application with
the IPUC requesting a determination that Idaho Power's expenditures of $220.8 million through year-end 2015 on relicensing of
the HCC were prudently incurred, and thus eligible for inclusion in retail rates in a future rate case. In December 2017, Idaho
Power filed with the IPUC a settlement stipulation signed by Idaho Power, the IPUC staff, and a third party intervenor
recognizing that a total of $216.5 million in HCC relicensing expenditures and other related costs were reasonably incurred,
and therefore should be eligible for inclusion in customer rates at a later date. The settlement stipulation is subject to review and
approval by the IPUC. As a result of filing the settlement stipulation, Idaho Power recorded a $5.0 million pre-tax charge in
2017. For more information relating to HCC relicensing costs, see Note 12 - "Property, Plant and Equipment and Jointly-
Owned Projects."
Idaho Energy Efficiency Rider: On an annual basis, Idaho Power applies to the IPUC for an order designating Idaho Power’s
prior calendar year Idaho Energy Efficiency Rider (Idaho Rider) funded expenses as prudently incurred. In 2012 and 2013, the
IPUC declined to decide the prudence of the increases in 2011 and 2012 Idaho Rider funded labor increases, while at the same
time offering Idaho Power another opportunity to provide sufficient evidence at a future time. In 2017, Idaho Power applied to
the IPUC for an order determining that the 2011 - 2016 Idaho Rider funded labor increases of $1.9 million were prudently
incurred and eligible for collection through the Idaho Rider. On October 16, 2017, the IPUC issued its order determining that
the 2011 - 2016 incremental Idaho Rider funded labor expenses of $1.9 million were prudently incurred. In its order, the IPUC
also authorized actual Idaho Rider funded wage increases after 2016. The IPUC determined that this process does not require
pre-determination as to prudence (up to a 2 percent annual cap), no longer requires labor to be examined in Idaho Power’s
annual prudence cases, and that the base wage level and annual cap will be reset in future general rate cases. The prudence
order resulted in a $2.4 million increase in operating income in 2017.
Tax Cuts and Jobs Act
On December 22, 2017, the Tax Cut and Jobs Act was signed into law. On January 17, 2018, the IPUC issued an order requiring
utilities within its jurisdiction, including Idaho Power, to 1) record a deferred regulatory liability for the estimated Idaho-
jurisdictional share of financial benefits after January 1, 2018, from the changes in the federal income tax law and 2) to file a
report with the IPUC by March 30, 2018, identifying and quantifying the income tax changes along with proposed tariff
schedule changes. The IPUC order requires Idaho Power to estimate the income tax changes by comparing actual 2017 federal
99
income tax expense components with what those federal income tax components would have been if the Tax Cuts and Jobs Act
had been effective for the full year of 2017. Idaho Power is currently working to comply with the IPUC order.
On December 29, 2017, Idaho Power filed an application with the OPUC, requesting authority to defer for later ratemaking
treatment the Oregon jurisdictional earnings in excess of the currently authorized Oregon jurisdictional rate of return on equity
that may result from the Tax Cuts and Jobs Act, as measured from the Company’s annual Oregon Results of Operations. On
December 29, 2017, OPUC Staff also filed an application with the OPUC requesting authority to defer for later ratemaking
treatment the difference between Idaho Power’s current retail rates and its current retail rates inclusive of the impact of the Tax
Cuts and Jobs Act.
Idaho Power is working with the IPUC and OPUC to determine how potential income tax expense reductions from the changes
in federal income tax law may benefit Idaho Power customers and affect IDACORP's and Idaho Power's financial condition
and results of operations. The method through which potential cost savings may be accrued for the benefit of customers,
including potential reductions to customer rates and to regulatory deferrals, will require approval from the IPUC and OPUC.
Valmy Base Rate Adjustment Settlement Stipulations
In May 2017, the IPUC approved a settlement stipulation allowing accelerated depreciation and cost recovery for Idaho
Power’s jointly-owned North Valmy coal-fired power plant (Valmy Plant). The settlement stipulation provides for an increase in
Idaho jurisdictional revenues of $13.3 million per year, and (1) levelized collections and associated cost recovery through
December 2028, (2) accelerated depreciation on unit 1 through 2019 and unit 2 through 2025, (3) Idaho Power to use prudent
and commercially reasonable efforts to end its participation in the operation of unit 1 by the end of 2019 and unit 2 by the end
of 2025, and (4) a filing no later than December 31, 2019 that would include actual and planned incremental investments in unit
2, including updated financial analysis regarding the lowest costs options for unit 2. The costs intended to be recovered by the
increased jurisdictional revenues include current investments as of May 31, 2017, in both units, forecasted unit 1 investments
from 2017 through 2019, and forecasted decommissioning costs for unit 1 and unit 2, offset by forecasted operation and
maintenance costs savings. The settlement stipulation also provides for the regulatory accrual or deferral of the difference
between actual revenue requirements and levelized collections, and provides for the regulatory accrual or deferral of the
difference between actual costs incurred (including accelerated depreciation expense on unit 1 through 2019 and unit 2 through
2025) compared with costs permitted to be recovered during the cost recovery period specified in the settlement stipulation
(including depreciation expense through 2028). If actual costs incurred differ from forecasted amounts included in the
settlement stipulation, collection or refund of any differences would be subject to regulatory approval.
In June 2017, the OPUC also approved a settlement stipulation allowing for accelerated depreciation of units 1 and 2 through
December 31, 2025, cost recovery of incremental Valmy Plant investments through May 31, 2017, and forecasted
decommissioning costs. The settlement stipulation provides for an increase in the Oregon jurisdictional revenue requirement of
$1.1 million, effective July 1, 2017, with yearly adjustments, if warranted.
Depreciation Rate Settlement Stipulations
In May 2017, the IPUC and OPUC approved settlement stipulations related to revised depreciation rates for Idaho Power's
electric plant in service other than the Valmy Plant, and adjusted base rates in Oregon to reflect the revised depreciation rates
applied to electric plant-in-service based on balances from the most recent general rate case. These settlement stipulations
provided for new depreciation rates to go into effect on June 1, 2017, with no significant resulting increase in revenue.
Western Energy Imbalance Market Costs
Idaho Power plans to participate in a new energy imbalance market implemented in the western United States (Western EIM).
In August 2016, Idaho Power filed an application with the IPUC requesting specified regulatory accounting treatment
associated with its participation in the Western EIM. In January 2017, the IPUC issued an order authorizing Idaho Power’s
requested deferral accounting treatment for costs associated with joining the Western EIM. Idaho Power can defer costs
incurred until the earlier of when Idaho Power begins recovery of the costs and the deferral balance or the end of 2018. Idaho
Power anticipates that its participation in the Western EIM will commence in April 2018.
In November 2017, Idaho Power filed an application with the IPUC requesting approval to establish an interim method of
recovery for costs associated with participation in the Western EIM. If the IPUC approves the application as filed, Idaho Power
intends to include $3.6 million in costs for recovery through the PCA, beginning June 1, 2018. Idaho Power has requested a
decision from the IPUC by March 31, 2018.

Notable Oregon Regulatory Matters
Oregon Base Rate Changes: Oregon base rates were most recently established in a general rate case in 2012. In February
2012, the OPUC issued an order approving a settlement stipulation that provided for a $1.8 million base rate increase, a return
on equity of 9.9 percent, and an overall rate of return of 7.757 percent in the Oregon jurisdiction. New rates in conformity with
the settlement stipulation were effective March 1, 2012. Subsequently, in September 2012, the OPUC issued an order approving
an approximately $3.0 million increase in annual Oregon jurisdiction base rates, effective October 1, 2012, for inclusion of the
Langley Gulch power plant in Idaho Power's Oregon rate base.
Federal Regulatory Matters - Open Access Transmission Tariff Rates
Idaho Power uses a formula rate for transmission service provided under its OATT, which allows transmission rates to be
updated annually based primarily on financial and operational data Idaho Power files with the FERC. Idaho Power's OATT
rates submitted to the FERC in Idaho Power's four most recent annual OATT Final Informational Filings were as follows:
Applicable Period
October 1, 2017 to September 30, 2018
October 1, 2016 to September 30, 2017
October 1, 2015 to September 30, 2016

OATT Rate (per
kW-year)

Idaho Power's current OATT rate is based on a net annual transmission revenue requirement of $130.4 million, which
represents the OATT formulaic determination of Idaho Power's net cost of providing OATT-based transmission service.

Long-Term Debt Issuances, Maturities, and Availability
On March 10, 2016, Idaho Power issued $120 million in principal amount of 4.05% first mortgage bonds, secured medium-
term notes, Series J, maturing on March 1, 2046. On April 11, 2016, Idaho Power redeemed, prior to maturity, $100 million in
principal amount of 6.15% first mortgage bonds, medium-term notes, Series H, due April 2019. In accordance with the
redemption provisions of the notes, the redemption included Idaho Power's payment of a make-whole premium to the holders
102
of the redeemed notes in the aggregate amount of approximately $14.0 million. Idaho Power used a portion of the net proceeds
from the March 2016 sale of first mortgage bonds, medium-term notes to effect the redemption.
On March 6, 2015, Idaho Power issued $250.0 million in principal amount of 3.65% first mortgage bonds, secured medium-
term notes, Series J, maturing on March 1, 2045. On April 23, 2015, Idaho Power redeemed, prior to maturity, $120.0 million
in principal amount of 6.025% first mortgage bonds, secured medium-term notes, Series H, due July 2018. In accordance with
the redemption provisions of the notes, the redemption included Idaho Power's payment of a make-whole premium to the
holders of the redeemed notes in the aggregate amount of approximately $17.9 million. Idaho Power used a portion of the net
proceeds from the March 2015 sale of first mortgage bonds, medium-term notes to effect the redemption.
In April and May 2016, Idaho Power received orders from the IPUC, OPUC, and Wyoming Public Service Commission
(WPSC) authorizing Idaho Power to issue and sell from time to time up to $500 million in aggregate principal amount of debt
securities and first mortgage bonds, subject to conditions specified in the orders. The order from the IPUC approved the
issuance of the securities through May 31, 2019, subject to extensions upon request to the IPUC. The OPUC's and WPSC's
orders do not impose a time limitation for issuances, but the OPUC order does impose a number of other conditions, including a
requirement that the interest rates for the debt securities or first mortgage bonds fall within either (a) designated spreads over
comparable U.S. Treasury rates or (b) a maximum all-in interest rate limit of 7.0 percent.
On May 20, 2016, IDACORP and Idaho Power filed a joint shelf registration statement with the U.S. Securities and Exchange
Commission (SEC), which became effective upon filing, for the offer and sale of, in the case of Idaho Power, an unspecified
principal amount of its first mortgage bonds and debt securities. On September 27, 2016, Idaho Power entered into a selling
agency agreement with seven banks named in the agreement in connection with the potential issuance and sale from time to
time of up to $500 million aggregate principal amount of first mortgage bonds, secured medium term notes, Series K (Series K
Notes), under Idaho Power’s Indenture of Mortgage and Deed of Trust, dated as of October 1, 1937, as amended and
supplemented (Indenture). At the same time, Idaho Power entered into the Forty-eighth Supplemental Indenture, dated as of
September 1, 2016, to the Indenture. The Forty-eighth Supplemental Indenture provides for, among other items, the issuance of
up to $500 million in aggregate principal amount of Series K Notes pursuant to the Indenture. As of December 31, 2017, $500
million in principal amount of Series K Notes remained available for issuance under the Indenture.
Mortgage: As of December 31, 2017, Idaho Power could issue under its Indenture approximately $1.8 billion of additional first
mortgage bonds based on retired first mortgage bonds and total unfunded property additions. These amounts are further limited
by the maximum amount of first mortgage bonds set forth in the Indenture.
The mortgage of the Indenture secures all bonds issued under the Indenture equally and ratably, without preference, priority, or
distinction. First mortgage bonds issued in the future will also be secured by the mortgage of the Indenture. The lien constitutes
a first mortgage on all the properties of Idaho Power, subject only to certain limited exceptions including liens for taxes and
assessments that are not delinquent and minor excepted encumbrances. Certain of the properties of Idaho Power are subject to
easements, leases, contracts, covenants, workmen's compensation awards, and similar encumbrances and minor defects and
clouds common to properties. The mortgage of the Indenture does not create a lien on revenues or profits, or notes or accounts
receivable, contracts or choses in action, except as permitted by law during a completed default, securities, or cash, except
when pledged, or merchandise or equipment manufactured or acquired for resale. The mortgage of the Indenture creates a lien
on the interest of Idaho Power in property subsequently acquired, other than excepted property, subject to limitations in the case
of consolidation, merger, or sale of all or substantially all of the assets of Idaho Power. The Indenture requires Idaho Power to
spend or appropriate 15 percent of its annual gross operating revenues for maintenance, retirement, or amortization of its
properties. Idaho Power may, however, anticipate or make up these expenditures or appropriations within the five years that
immediately follow or precede a particular year.
The Forty-eighth Supplemental Indenture increased the maximum amount of first mortgage bonds issuable by Idaho Power
under the Indenture from $2.0 billion to $2.5 billion. The amount issuable is also restricted by property, earnings, and other
provisions of the Indenture and supplemental indentures to the Indenture. Idaho Power may amend the Indenture and increase
this amount without consent of the holders of the first mortgage bonds. The Indenture requires that Idaho Power's net earnings
be at least twice the annual interest requirements on all outstanding debt of equal or prior rank, including the bonds that Idaho
Power may propose to issue. Under certain circumstances, the net earnings test does not apply, including the issuance of
refunding bonds to retire outstanding bonds that mature in less than two years or that are of an equal or higher interest rate, or
prior lien bonds.

5. NOTES PAYABLE
Credit Facilities
On November 6, 2015, IDACORP and Idaho Power entered into Credit Agreements replacing the existing Second Amended
and Restated Credit Agreements, dated October 26, 2011, to provide credit facilities that may be used for general corporate
purposes and commercial paper backup. IDACORP's credit facility consists of a revolving line of credit not to exceed the
aggregate principal amount at any one time outstanding of $100 million, including swingline loans in an aggregate principal
amount at any time outstanding not to exceed $10 million, and letters of credit in an aggregate principal amount at any time
outstanding not to exceed $50 million. Idaho Power's credit facility consists of a revolving line of credit, through the issuance
of loans and standby letters of credit, not to exceed the aggregate principal amount at any one time outstanding of $300 million,
including swingline loans in an aggregate principal amount at any time outstanding not to exceed $30 million, and letters of
credit in an aggregate principal amount at any time outstanding not to exceed $100 million. IDACORP and Idaho Power have
the right to request an increase in the aggregate principal amount of the facilities to $150 million and $450 million, respectively,
in each case subject to certain conditions.
The IDACORP and Idaho Power credit facilities have similar terms and conditions. The interest rates for any borrowings under
the facilities are based on either (1) a floating rate that is equal to the highest of the prime rate, federal funds rate plus 0.5
percent, or LIBOR rate plus 1.0 percent, or (2) the LIBOR rate, plus, in each case, an applicable margin, provided that the
federal funds rate and LIBOR rate will not be less than 0.0 percent. The margin is based on IDACORP's or Idaho Power's, as
applicable, senior unsecured long-term indebtedness credit rating by Moody's Investors Service, Inc., Standard and Poor's
Ratings Services, and Fitch Rating Services, Inc., as set forth on a schedule to the credit agreements. Under their respective
credit facilities, the companies pay a facility fee on the commitment based on the respective company's credit rating for senior
unsecured long-term debt securities. While the credit facilities provide for an original maturity date of November 6, 2020, the
credit agreements grant IDACORP and Idaho Power the right to request up to two one-year extensions, subject to certain
conditions. On November 7, 2017, IDACORP and Idaho Power executed the second extension agreement with the consent of
all the lenders, extending the maturity date under both credit agreements to November 4, 2022. No other terms of the credit
facilities, included the amount of permitted borrowing under the credit agreements, were affected by the extensions.
At December 31, 2017, no loans were outstanding under either IDACORP's or Idaho Power's facilities. At December 31, 2017,
Idaho Power had regulatory authority to incur up to $450 million in principal amount of short-term indebtedness at any one
time outstanding. Balances (in thousands of dollars) and interest rates of IDACORP’s and Idaho Power's short-term borrowings
were as follows at December 31, 2017, and December 31, 2016:

During 2017, IDACORP granted 72,397 restricted stock unit awards to employees and 12,050 shares of common stock to directors but made no original
issuances of shares of common stock pursuant to the IDACORP, Inc. 2000 Long-Term Incentive and Compensation Plan.
In recent years, IDACORP has entered into sales agency agreements under which IDACORP could offer and sell shares of its
common stock from time to time through an agent. The most recent sales agency agreement expired in May 2016, but
IDACORP may choose to enter into a new sales agency agreement in the future. On May 20, 2016, IDACORP filed a shelf
registration statement with the SEC, which became effective upon filing, for the potential offer and sale of an unspecified
amount of shares of common stock.
Restrictions on Dividends
Idaho Power’s ability to pay dividends on its common stock held by IDACORP and IDACORP’s ability to pay dividends on its
common stock are limited to the extent payment of such dividends would violate the covenants in their respective credit
facilities or Idaho Power’s Revised Code of Conduct. A covenant under IDACORP’s credit facility and Idaho Power’s credit
facility requires IDACORP and Idaho Power to maintain leverage ratios of consolidated indebtedness to consolidated total
capitalization, as defined therein, of no more than 65 percent at the end of each fiscal quarter. At December 31, 2017, the
leverage ratios for IDACORP and Idaho Power were 44 percent and 46 percent, respectively. Based on these restrictions,
IDACORP’s and Idaho Power’s dividends were limited to $1.3 billion and $1.1 billion, respectively, at December 31,
2017. There are additional facility covenants, subject to exceptions, that prohibit or restrict the sale or disposition of property
without consent and any agreements restricting dividend payments to the company from any material subsidiary. At
December 31, 2017, IDACORP and Idaho Power were in compliance with those covenants.
Idaho Power’s Revised Policy and Code of Conduct relating to transactions between and among Idaho Power, IDACORP, and
other affiliates, which was approved by the IPUC in April 2008, provides that Idaho Power will not pay any dividends to
IDACORP that will reduce Idaho Power’s common equity capital below 35 percent of its total adjusted capital without IPUC
approval. At December 31, 2017, Idaho Power's common equity capital was 54 percent of its total adjusted capital. Further,
Idaho Power must obtain approval from the OPUC before it can directly or indirectly loan funds or issue notes or give credit on
its books to IDACORP.
Idaho Power’s articles of incorporation contain restrictions on the payment of dividends on its common stock if preferred stock
dividends are in arrears. As of the date of this report, Idaho Power has no preferred stock outstanding.
In addition to contractual restrictions on the amount and payment of dividends, the Federal Power Act (FPA) prohibits the
payment of dividends from "capital accounts." The term "capital account" is undefined in the FPA or its regulations, but Idaho
Power does not believe the restriction would limit Idaho Power's ability to pay dividends out of current year earnings or
retained earnings.
105
7. SHARE-BASED COMPENSATION
IDACORP has one share-based compensation plan -- the 2000 Long-Term Incentive and Compensation Plan (LTICP). The
1994 Restricted Stock Plan was terminated effective February 9, 2017. The LTICP (for officers, key employees, and directors)
permits the grant of stock options, restricted stock and restricted stock units (together, Restricted Stock), performance shares
and performance-based units (together, Performance-Based Shares), and several other types of share-based awards. At
December 31, 2017, the maximum number of shares available under the LTICP was 836,220.
Restricted Stock and Performance-Based Shares Awards
Restricted Stock awards have three-year vesting periods and entitle the recipients to dividends or dividend equivalents, as
applicable, and voting rights, except that holders of restricted stock units do not have voting rights until the units are vested and
settled in shares. Unvested awards are restricted as to disposition and subject to forfeiture under certain circumstances. The fair
value of these awards is based on the closing market price of common stock on the grant date and is charged to compensation
expense over the vesting period, based on the number of shares expected to vest.
Performance-Based Shares awards have three-year vesting periods and entitle the recipients to voting rights, except that holders
of performance-based units do not have voting rights until the units are vested and settled in shares. Unvested awards are
restricted as to disposition, subject to forfeiture under certain circumstances, and subject to the attainment of specific
performance conditions over the three-year vesting period. The performance conditions are two equally-weighted metrics,
cumulative earnings per share (CEPS) and total shareholder return (TSR) relative to a peer group. Depending on the level of
attainment of the performance conditions and the year issued, the final number of shares awarded can range from zero to 200
percent of the target award. Dividends or dividend equivalents, as applicable, are accrued during the vesting period and paid out
based on the final number of shares awarded.
The grant-date fair value of the CEPS portion is based on the closing market value at the date of grant, reduced by the loss in
time-value of the estimated future dividend payments. The fair value of this portion of the awards is charged to compensation
expense over the requisite service period, based on the number of shares expected to vest. The grant-date fair value of the TSR
portion is estimated using the market value at the date of grant and a statistical model that incorporates the probability of
meeting performance targets based on historical returns relative to the peer group. The fair value of this portion of the awards is
charged to compensation expense over the requisite service period, provided the requisite service period is rendered, regardless
of the level of TSR metric attained.
A summary of Restricted Stock and Performance-Based Shares award activity is presented below. Idaho Power share amounts

The total fair value of shares vested was $7.5 million in 2017 and $8.3 million in both 2016 and 2015. At December 31, 2017,
IDACORP had $5.5 million of total unrecognized compensation cost related to nonvested share-based compensation that was
expected to vest. Idaho Power’s share of this amount was $5.4 million. These costs are expected to be recognized over a
weighted-average period of 1.7 years. IDACORP uses original issue and/or treasury shares for these awards.
In 2017, a total of 12,050 shares were awarded to directors at a grant date fair value of $82.93 per share. Directors elected to
defer receipt of 3,012 of these shares, which are being held as deferred stock units with dividend equivalents reinvested in
additional stock units.

As of December 31, 2017, Idaho Power had 1,114 MW nameplate capacity of PURPA-related projects on-line, with an
additional 5 MW nameplate capacity of projects projected to be on-line in 2018 and an additional 24 MW expected to be added
in 2019. The power purchase contracts for these projects have original contract terms ranging from one to 35 years. Idaho
Power's expenses associated with PURPA-related projects were approximately $170 million in 2017, $154 million in 2016, and
$131 million in 2015.

Guarantees
Through a self-bonding mechanism, Idaho Power guarantees its portion of reclamation activities and obligations at BCC, of
which IERCo owns a one-third interest. This guarantee, which is renewed annually with the Wyoming Department of
Environmental Quality, was $56.7 million at December 31, 2017, representing IERCo's one-third share of BCC's total
reclamation obligation of $170.1 million. BCC has a reclamation trust fund set aside specifically for the purpose of paying these
reclamation costs. At December 31, 2017, the value of the reclamation trust fund was $103.4 million. During 2017, the
reclamation trust fund made no distributions for reclamation activity costs associated with the BCC surface mine. BCC
periodically assesses the adequacy of the reclamation trust fund and its estimate of future reclamation costs. To ensure that the
reclamation trust fund maintains adequate reserves, BCC has the ability to, and does, add a per-ton surcharge to coal sales, all
of which are made to the Jim Bridger plant. Because of the existence of the fund and the ability to apply a per-ton surcharge, the
estimated fair value of this guarantee is minimal.
IDACORP and Idaho Power enter into financial agreements and power purchase and sale agreements that include
indemnification provisions relating to various forms of claims or liabilities that may arise from the transactions contemplated by
these agreements. Generally, a maximum obligation is not explicitly stated in the indemnification provisions and, therefore, the
overall maximum amount of the obligation under such indemnification provisions cannot be reasonably estimated. IDACORP
and Idaho Power periodically evaluate the likelihood of incurring costs under such indemnities based on their historical
experience and the evaluation of the specific indemnities. As of December 31, 2017, management believes the likelihood is
remote that IDACORP or Idaho Power would be required to perform under such indemnification provisions or otherwise incur
any significant losses with respect to such indemnification obligations. Neither IDACORP nor Idaho Power has recorded any
liability on their respective consolidated balance sheets with respect to these indemnification obligations.
10. CONTINGENCIES
IDACORP and Idaho Power have in the past and expect in the future to become involved in various claims, controversies,
disputes, and other contingent matters, some of which involve litigation and regulatory or other contested proceedings. The
ultimate resolution and outcome of litigation and regulatory proceedings is inherently difficult to determine, particularly where
(a) the remedies or penalties sought are indeterminate, (b) the proceedings are in the early stages or the substantive issues have
not been well developed, or (c) the matters involve complex or novel legal theories or a large number of parties. In accordance
with applicable accounting guidance, IDACORP and Idaho Power, as applicable, establish an accrual for legal proceedings
when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable. If
the loss contingency at issue is not both probable and reasonably estimable, IDACORP and Idaho Power do not establish an
accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable
and reasonably estimable. As of the date of this report, IDACORP's and Idaho Power's accruals for loss contingencies are not
material to their financial statements as a whole; however, future accruals could be material in a given period. IDACORP's and
Idaho Power's determination is based on currently available information, and estimates presented in financial statements and
other financial disclosures involve significant judgment and may be subject to significant uncertainty. For matters that affect
Idaho Power's operations, Idaho Power intends to seek, to the extent permissible and appropriate, recovery through the
ratemaking process of costs incurred, although there is no assurance that such recovery would be granted.
IDACORP and Idaho Power are parties to legal claims and legal and regulatory actions and proceedings in the ordinary course
of business that are in addition to those discussed above and, as noted above, record an accrual for associated loss contingencies
when they are probable and reasonably estimable. As of the date of this report, the companies believe that resolution of those
matters will not have a material adverse effect on their respective consolidated financial statements. Idaho Power is also
actively monitoring various pending environmental regulations and recently issued executive orders related to environmental
matters that may have a significant impact on its future operations. Given uncertainties regarding the outcome, timing, and
compliance plans for these environmental matters, Idaho Power is unable to estimate the financial impact of these regulations.
11. BENEFIT PLANS
Idaho Power sponsors defined benefit and other postretirement benefit plans that cover the majority of its employees. Idaho
Power also sponsors a defined contribution 401(k) employee savings plan and provides certain post-employment benefits.
108
Pension Plans
Idaho Power has two pension plans–a noncontributory defined benefit pension plan (pension plan) and two nonqualified
defined benefit pension plans for certain senior management employees called the Security Plan for Senior Management
Employees I and Security Plan for Senior Management Employees II (together, SMSP). Idaho Power also has a nonqualified
defined benefit pension plan for directors that was frozen in 2002. Remaining vested benefits from that plan are included with
the SMSP in the disclosures below. The benefits under these plans are based on years of service and the employee's final
average earnings.
Idaho Power’s funding policy for the pension plan is to contribute at least the minimum required under the Employee
Retirement Income Security Act of 1974 (ERISA) but not more than the maximum amount deductible for income tax purposes.
In 2017, 2016, and 2015 Idaho Power elected to contribute more than the minimum required amounts in order to bring the
pension plan to a more funded position, to reduce future required contributions, and to reduce Pension Benefit Guaranty
Corporation premiums.

As a non-qualified plan, the SMSP has no plan assets. However, Idaho Power has a Rabbi trust designated to provide funding
for SMSP obligations. The Rabbi trust holds investments in marketable securities and corporate-owned life insurance. The
109
recorded value of these investments was approximately $85.7 million and $77.8 million at December 31, 2017 and 2016,
respectively, and is reflected in Investments and in Company-owned life insurance on the consolidated balance sheets.
The following table shows the components of net periodic benefit cost for these plans (in thousands of dollars). For purposes of

(1) Net periodic benefit costs for the pension plan are recognized for financial reporting based upon the authorization of each regulatory jurisdiction in which
Idaho Power operates. Under IPUC order, the Idaho portion of net periodic benefit cost is recorded as a regulatory asset and is recognized in the income
statement as those costs are recovered through rates.

In 2018, IDACORP and Idaho Power expect to recognize as components of net periodic benefit cost $17.5 million from
amortizing amounts recorded in accumulated other comprehensive income (or as a regulatory asset for the pension plan) as of
December 31, 2017, relating to the pension plan and SMSP. This amount consists of $13.6 million of amortization of net loss
for the pension plan and $3.8 million of amortization of net loss and $0.1 million of amortization of prior service cost for the
SMSP.

As of December 31, 2017, IDACORP's and Idaho Power's minimum required contributions to the pension plan are estimated to
be zero in 2018. Depending on market conditions and cash flow considerations in 2018, Idaho Power could contribute up to $40
million to the pension plan during 2018 in order to help balance the regulatory collection of these expenditures with the amount
and timing of contributions and to mitigate the cost of being in an underfunded position.

Postretirement Benefits
Idaho Power maintains a defined benefit postretirement benefit plan (consisting of health care and death benefits) that covers all
employees who were enrolled in the active-employee group plan at the time of retirement as well as their spouses and
qualifying dependents. Retirees hired on or after January 1, 1999, have access to the standard medical option at full cost, with
no contribution by Idaho Power. Benefits for employees who retire after December 31, 2002, are limited to a fixed amount,
which has limited the growth of Idaho Power’s future obligations under this plan.

component that is based on employees' years of service. Merit salary increases are assumed to be 8.0% for employees in their first year of service and scale
down to 0% for employees in their fortieth year of service and beyond.

The assumed health care cost trend rate used to measure the expected cost of health benefits covered by the postretirement plan
was 6.8 percent in 2017 and is assumed to decrease to 6.4 percent in 2018, 5.9 percent in 2019, 5.4 percent in 2020 and to
gradually decrease to 4.1 percent by 2074. The assumed dental cost trend rate used to measure the expected cost of dental
benefits covered by the plan was 4.0 percent, or equal to the medical trend rate if lower, for all years. A one percentage point
change in the assumed health care cost trend rate would have the following effects at December 31, 2017 (in thousands of

Assets are rebalanced as necessary to keep the portfolio close to target allocations.
The plan’s principal investment objective is to maximize total return (defined as the sum of realized interest and dividend
income and realized and unrealized gain or loss in market price) consistent with prudent parameters of risk and the liability
profile of the portfolio. Emphasis is placed on preservation and growth of capital along with adequacy of cash flow sufficient to
fund current and future payments to pensioners.
The three major goals in Idaho Power’s asset allocation process are to:
determine if the investments have the potential to earn the rate of return assumed in the actuarial liability calculations;
•
• match the cash flow needs of the plan. Idaho Power sets bond allocations sufficient to cover at least five years of
benefit payments and cash allocations sufficient to cover the current year benefit payments. Idaho Power then utilizes
growth instruments (equities, real estate, venture capital) to fund the longer-term liabilities of the plan; and
• maintain a prudent risk profile consistent with ERISA fiduciary standards.
Allowable plan investments include stocks and stock funds, investment-grade bonds and bond funds, real estate funds, private
equity funds, and cash and cash equivalents. With the exception of real estate holdings and private equity, investments must be
readily marketable so that an entire holding can be disposed of quickly with only a minor effect upon market price.
Rate-of-return projections for plan assets are based on historical risk/return relationships among asset classes. The primary
measure is the historical risk premium each asset class has delivered versus the yield on the Moody's AA Corporate Bond
Index. This historical risk premium is then added to the current yield on the Moody's AA Corporate Bond Index. Additional
analysis is performed to measure the expected range of returns, as well as worst-case and best-case scenarios. Based on the
current low interest rate environment, current rate-of-return expectations are lower than the nominal returns generated over the
past 20 years when interest rates were generally much higher.
Idaho Power’s asset modeling process also utilizes historical market returns to measure the portfolio’s exposure to a “worst-
case” market scenario, to determine how much performance could vary from the expected “average” performance over various
time periods. This “worst-case” modeling, in addition to cash flow matching and diversification by asset class and investment
style, provides the basis for managing the risk associated with investing portfolio assets.

Fair Value of Plan Assets: Idaho Power classifies its pension plan and postretirement benefit plan investments using the three-

Fair Value Measurement of Level 2 Plan assets and Plan assets measured at NAV:
Level 2 Bonds: These investments represent U.S. government, agency bonds, and corporate bonds. The U.S. government and
agency bonds, as well as the corporate bonds, are not traded on an exchange and are valued utilizing market prices for similar
assets or liabilities in active markets.
Level 2 Postretirement Asset: This asset represents an investment in a life insurance contract and is recorded at fair value,
which is the cash surrender value, less any unpaid expenses. The cash surrender value of this insurance contract is contractually
equal to the insurance contract's proportionate share of the market value of an associated investment account held by the
insurer. The investments held by the insurer's investment account are all instruments traded on exchanges with readily
determinable market prices.
Commingled Funds: These funds, made up of the international, emerging markets equity securities, and commodities fund
measured at NAV, are not publicly traded, and therefore no publicly quoted market price is readily available. The value of the
commingled funds are presented at estimated fair value, which is determined based on the unit value of the fund. The values of
these investments are calculated by the custodian for the fund company on a monthly or more frequent basis, and are based on
market prices of the assets held by each of the commingled funds divided by the number of fund shares outstanding for the
respective fund. The investments in commingled funds have redemption limitations that permit monthly redemption following
notice requirements of 5 to 7 days.
Real Estate: Real estate holdings represent investments in open-ended commingled real estate funds. As the property interests
held in these real estate funds are not frequently traded, establishing the market value of the property interests held by the fund,
and the resulting unit value of fund shareholders, is based on unobservable inputs including property appraisals by the fund
companies, property appraisals by independent appraisal firms, analysis of the replacement cost of the property, discounted cash
flows generated by property rents and changes in property values, and comparisons with sale prices of similar properties in
similar markets. These open-ended real estate funds also furnish annual audited financial statements that are also used to further
validate the information provided. Redemptions are generally available on a quarterly basis, with 10 to 35 days written notice,
depending on the individual fund. If the fund has sufficient liquidity, the redemption will be processed at the fund NAV or the
fund’s estimate of fair value at the end of the quarter. If the fund does not have sufficient liquidity to honor the full redemption,
the remainder will be set for redemption the following quarter on a pro-rata basis with other redemption requests. This same
process will repeat until the redemption request has been completed. To protect other fund holders, real estate funds have no
duty to liquidate or encumber funds to meet redemption requests.
Private Market Investments: Private market investments represent two categories: fund of hedge funds and venture capital
funds. These funds are valued by the fund companies based on the estimated fair values of the underlying fund holdings divided
by the fund shares outstanding or multiplied by the ownership percentages of the holder. Some hedge fund strategies utilize
securities with readily available market prices, while others utilize less liquid investment vehicles that are valued based on
unobservable inputs including cost, operating results, recent funding activity, or comparisons with similar investment vehicles.
Redemptions are available on a quarterly basis with 70 days written notice. Redemptions will be processed at the quarterly
NAV or fair value within 60 days following quarter end. In the event of a full redemption, a reserve amount of 5% to 10% of
the redemption amount may be held in reserve until the audited financial statements of the fund are published. This allows the
fund to adjust the redemption so that other fund holders are not adversely impacted. Venture capital fund investments are valued
by the fund companies based on estimated fair value of the underlying fund holdings divided by the fund shares outstanding.
Some venture capital investments have progressed to the point that they have readily available exchange-based market
valuations. Early stage venture investments are valued based on unobservable inputs including cost, operating results,
discounted cash flows, the price of recent funding events, or pending offers from other viable entities. These private market
investments furnish annual audited financial statements that are also used to further validate the information provided. These
funds are formed for a stated life of 10 to 15 years. The general partner can extend the fund life for 2 or 3 one-year periods. The
fund can be further extended with the approval of the limited partners. There are generally no redemption rights associated with
these funds. The limited partner must hold the fund for the life of the fund or find a third-party buyer.
Employee Savings Plan
Idaho Power has a defined contribution plan designed to comply with Section 401(k) of the Internal Revenue Code and that
covers substantially all employees. Idaho Power matches specified percentages of employee contributions to the plan. Matching
annual contributions were approximately $7.4 million , $7.5 million, and $6.9 million in 2017, 2016, and 2015, respectively.
115
Post-employment Benefits
Idaho Power provides certain benefits to former or inactive employees, their beneficiaries, and covered dependents after
employment but before retirement, in addition to the health care benefits required under the Consolidated Omnibus Budget
Reconciliation Act. These benefits include salary continuation, health care and life insurance for those employees found to be
disabled under Idaho Power’s disability plans, and health care for surviving spouses and dependents. Idaho Power accrues a
liability for such benefits. The post employment benefits included in other deferred credits on both IDACORP’s and Idaho
Power’s consolidated balance sheets at December 31, 2017, 2016, and 2015, were approximately $2 million.

At December 31, 2017, Idaho Power's construction work in progress balance of $452.4 million included relicensing costs of
$268.7 million for the HCC, Idaho Power's largest hydroelectric complex. In 2017, 2016, and 2015, the IPUC authorized Idaho
Power to include in its Idaho jurisdiction rates $6.5 million annually ($10.7 million when grossed-up for the effect of income
taxes) of AFUDC relating to the HCC relicensing project. Collecting these amounts will reduce the amount collected in the
future once the HCC relicensing costs are approved for recovery in base rates. At December 31, 2017, Idaho Power's regulatory
liability for collection of AFUDC relating to the HCC was $119.7 million.
Idaho Power's ownership interest in three jointly-owned generating facilities is included in the table above. Under the joint
operating agreements for these facilities, each participating utility is responsible for financing its share of construction,
operating, and leasing costs. Idaho Power's proportionate share of operating expenses for each facility is included in the
Consolidated Statements of Income. These jointly-owned facilities, including balance sheet amounts and the extent of Idaho
Power’s participation, were as follows at December 31, 2017 (in thousands of dollars):

IERCo, Idaho Power’s wholly-owned subsidiary, is a joint venturer in BCC. Idaho Power’s coal purchases from the joint
venture were $86.4 million in 2017, $92.9 million in 2016, and $92.8 million in 2015.
Idaho Power has contracts to purchase the energy from four PURPA qualified facilities that are 50 percent owned by Ida-West.
Idaho Power’s power purchases from these facilities were $9.8 million in 2017, $7.8 million in 2016, and $8.1 million in 2015.
IDACORP's consolidated VIE, Marysville, owns a hydroelectric plant with a net book value of $15.7 million and $16.2 million
at December 31, 2017 and 2016, respectively.

13. ASSET RETIREMENT OBLIGATIONS (ARO)
The guidance relating to accounting for AROs requires that legal obligations associated with the retirement of property, plant,
and equipment be recognized as a liability at fair value when incurred and when a reasonable estimate of the fair value of the
liability can be made. Under the guidance, when a liability is initially recorded, the entity increases the carrying amount of the
related long-lived asset to reflect the future retirement cost. Over time, the liability is accreted to its estimated settlement value
and paid, and the capitalized cost is depreciated over the useful life of the related asset. If, at the end of the asset’s life, the
recorded liability differs from the actual obligations paid, a gain or loss would be recognized. As a rate-regulated entity, Idaho
Power records regulatory assets or liabilities instead of accretion, depreciation, and gains or losses, as approved by the IPUC.
The regulatory assets recorded under this order do not earn a return on investment. Beginning June 1, 2012, accretion,
depreciation, and gains or losses related to the Boardman generating facility have been exempted from such regulatory
treatment as Idaho Power is now collecting amounts related to the decommissioning of Boardman in rates.
Idaho Power’s recorded AROs relate to the removal of polychlorinated biphenyl-contaminated equipment at its distribution
facilities and the reclamation and removal costs at its jointly-owned coal-fired generation facilities.
Idaho Power also has additional AROs associated with its transmission system, hydroelectric facilities, natural gas-fired
generation facilities, and jointly owned coal-fired generation facilities; however, due to the indeterminate removal date, the fair
value of the associated liabilities currently cannot be estimated and no amounts are recognized in the consolidated financial
statements.
The regulated operations of Idaho Power also collect removal costs in rates for certain assets that do not have associated AROs.
Idaho Power is required to redesignate these removal costs as regulatory liabilities. See Note 3 - "Regulatory Matters" for the
removal costs recorded as regulatory liabilities on IDACORP’s and Idaho Power’s consolidated balance sheets as of
December 31, 2017 and 2016.

IFS invests primarily in affordable housing developments, which provide a return principally by reducing federal and state
income taxes through tax credits and accelerated tax depreciation benefits. IFS has focused on a diversified approach to its
investment strategy in order to limit both geographic and operational risk, with most of IFS’s investments having been made
through syndicated funds. IDACORP accounts for its equity-method investments in qualified affordable housing projects using
the proportional amortization method and recognizes the net investment performance in the consolidated statements of income
as a component of income tax expense.
15. DERIVATIVE FINANCIAL INSTRUMENTS
Commodity Price Risk
Idaho Power is exposed to market risk relating to electricity, natural gas, and other fuel commodity prices, all of which are
heavily influenced by supply and demand. Market risk may be influenced by market participants’ nonperformance of their
contractual obligations and commitments, which affects the supply of or demand for the commodity. Idaho Power uses
derivative instruments, such as physical and financial forward contracts, for both electricity and fuel to manage the risks
relating to these commodity price exposures. The primary objectives of Idaho Power’s energy purchase and sale activity are to
meet the demand of retail electric customers, maintain appropriate physical reserves to ensure reliability, and make economic
use of temporary surpluses that may develop.
All of Idaho Power's derivative instruments have been entered into for the purpose of economically hedging forecasted
purchases and sales, though none of these instruments have been designated as cash flow hedges. Idaho Power offsets fair value
amounts recognized on its balance sheet and applies collateral related to derivative instruments executed with the same
counterparty under the same master netting agreement. Idaho Power does not offset a counterparty's current derivative contracts
with the counterparty's long-term derivative contracts, although Idaho Power's master netting arrangements would allow current
and long-term positions to be offset in the event of default. Also, in the event of default, Idaho Power's master netting
arrangements would allow for the offsetting of all transactions executed under the master netting arrangement. These types of
transactions may include non-derivative instruments, derivatives qualifying for scope exceptions, receivables and payables
arising from settled positions, and other forms of non-cash collateral (such as letters of credit). These types of transactions are
excluded from the offsetting presented in the derivative fair value and offsetting table below.

At December 31, 2017, Idaho Power did not have material credit risk exposure from financial instruments, including
derivatives. Idaho Power monitors credit risk exposure through reviews of counterparty credit quality, corporate-wide
counterparty credit exposure, and corporate-wide counterparty concentration levels. Idaho Power manages these risks by
establishing credit and concentration limits on transactions with counterparties and requiring contractual guarantees, cash
deposits, or letters of credit from counterparties or their affiliates, as deemed necessary. Idaho Power’s physical power contracts
are commonly under Western Systems Power Pool agreements, physical gas contracts are usually under North American Energy
Standards Board contracts, and financial transactions are usually under International Swaps and Derivatives Association, Inc.
contracts. These contracts contain adequate assurance clauses requiring collateralization if a counterparty has debt that is
downgraded below investment grade by at least one rating agency.
Credit-Contingent Features
Certain of Idaho Power's derivative instruments contain provisions that require Idaho Power's unsecured debt to maintain an
investment grade credit rating from Moody's Investors Service and Standard & Poor's Ratings Services. If Idaho Power's
unsecured debt were to fall below investment grade, it would be in violation of these provisions, and the counterparties to the
derivative instruments could request immediate payment or demand immediate and ongoing full overnight collateralization on
derivative instruments in net liability positions. The aggregate fair value of all derivative instruments with credit-risk-related
contingent features that were in a liability position at December 31, 2017, was $2.0 million. Idaho Power posted $0.9 million
cash collateral related to this amount. If the credit-risk-related contingent features underlying these agreements were triggered
on December 31, 2017, Idaho Power would have been required to pay or post collateral to its counterparties up to an additional
$4.5 million to cover open liability positions as well as completed transactions that have not yet been paid.
16. FAIR VALUE MEASUREMENTS
IDACORP and Idaho Power have categorized their financial instruments into a three-level fair value hierarchy, based on the
priority of the inputs to the valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active
markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to
measure the financial instruments fall within different levels of the hierarchy, the categorization is based on the lowest level
input that is significant to the fair value measurement of the instrument.
Financial assets and liabilities recorded on the consolidated balance sheets are categorized based on the inputs to the valuation
techniques as follows:
• Level 1: Financial assets and liabilities whose values are based on unadjusted quoted prices for identical assets or
liabilities in an active market that IDACORP and Idaho Power have the ability to access.
• Level 2: Financial assets and liabilities whose values are based on the following:
a) quoted prices for similar assets or liabilities in active markets;
b) quoted prices for identical or similar assets or liabilities in non-active markets;
c) pricing models whose inputs are observable for substantially the full term of the asset or liability; and
d) pricing models whose inputs are derived principally from or corroborated by observable market data through
correlation or other means for substantially the full term of the asset or liability.
120
IDACORP and Idaho Power Level 2 inputs are based on quoted market prices adjusted for location using
corroborated, observable market data.
• Level 3: Financial assets and liabilities whose values are based on prices or valuation techniques that require inputs
that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s
own assumptions about the assumptions a market participant would use in pricing the asset or liability.
IDACORP’s and Idaho Power’s assessment of a particular input's significance to the fair value measurement requires judgment
and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy. An item
recorded at fair value is reclassified among levels when changes in the nature of valuation inputs cause the item to no longer
meet the criteria for the level in which it was previously categorized. There were no transfers between levels or material
changes in valuation techniques or inputs during the years ended December 31, 2017 and 2016.
The following table presents information about IDACORP’s and Idaho Power’s assets and liabilities measured at fair value on a

Idaho Power’s derivatives are contracts entered into as part of its management of loads and resources. Electricity derivatives are
valued on the Intercontinental Exchange (ICE) with quoted prices in an active market. Natural gas and diesel derivative
valuations are performed using New York Mercantile Exchange (NYMEX) and ICE pricing, adjusted for location basis, which
are also quoted under NYMEX and ICE pricing. Trading securities consist of employee-directed investments held in a Rabbi
trust and are related to an executive deferred compensation plan. Available-for-sale securities are related to the SMSP, are held
in a Rabbi trust, and are actively traded money market and exchange-traded funds with quoted prices in active markets.

Notes receivable are related to Ida-West and are valued based on unobservable inputs, including discounted cash flows, which
are partially based on forecasted hydroelectric conditions. Long-term debt is not traded on an exchange and is valued using
121
quoted rates for similar debt in active markets. Carrying values for cash and cash equivalents, deposits, customer and other
receivables, notes payable, accounts payable, interest accrued, and taxes accrued approximate fair value.
17. SEGMENT INFORMATION
IDACORP’s only reportable segment is utility operations. The utility operations segment’s primary source of revenue is the
regulated operations of Idaho Power. Idaho Power’s regulated operations include the generation, transmission, distribution,
purchase, and sale of electricity. This segment also includes income from IERCo, a wholly-owned subsidiary of Idaho Power
that is also subject to regulation and is a one-third owner of BCC, an unconsolidated joint venture.
IDACORP’s other operating segments are below the quantitative and qualitative thresholds for reportable segments and are
included in the “All Other” category in the table below. This category is comprised of IFS’s investments in affordable housing
developments and historic rehabilitation projects, Ida-West’s joint venture investments in small hydroelectric generation
projects, the remaining activities of IDACORP Energy Services Co., the successor to which wound down its energy marketing
operations in 2003, and IDACORP’s holding company expenses.
The table below summarizes the segment information for IDACORP’s utility operations and the total of all other segments, and

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholders and the Board of Directors of IDACORP, Inc.
We have audited the accompanying consolidated balance sheets of IDACORP, Inc. and subsidiaries (the “Company”) as of
December 31, 2017 and 2016, and the related consolidated statements of income, comprehensive income, equity, and cash
flows for each of the three years in the period ended December 31, 2017, and the related notes and the schedules listed in the
Index at Item 8 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in
all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations
and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles
generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States)
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2017, based on the criteria established in
Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway
Commission and our report dated February 22, 2018, expressed an unqualified opinion on the Company’s internal control over
financial reporting.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on
the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are
required to be independent with respect to the Company 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. 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.

Internal Control Over Financial Reporting - IDACORP, Inc.
Management’s Annual Report on Internal Control Over Financial Reporting
The management of IDACORP is responsible for establishing and maintaining adequate internal control over financial
reporting for IDACORP. Internal control over financial reporting is defined in Rule 13a-15(f) promulgated under the Securities
Exchange Act of 1934 as a process designed by, or under the supervision of, the company’s principal executive and principal
financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with accounting principles generally accepted in the United States of America and includes those policies and
procedures that:
•
•
•
pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and
dispositions of the assets of the company;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements
in accordance with accounting principles generally accepted in the United States of America, and that receipts and
expenditures of the company are being made only in accordance with the authorizations of management and directors
of the company; and
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition
of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.
Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
IDACORP’s management assessed the effectiveness of the company’s internal control over financial reporting as of
December 31, 2017. In making this assessment, the company’s management used the criteria set forth by the Committee of
Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013).
Based on its assessment, management concluded that, as of December 31, 2017, IDACORP’s internal control over financial
reporting is effective based on those criteria.
IDACORP’s independent registered public accounting firm has audited the financial statements included in this Annual Report
on Form 10-K for the year ended December 31, 2017 and issued a report, which appears on the next page and expresses an

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholders and the Board of Directors of IDACORP, Inc.
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of IDACORP, Inc. and subsidiaries (the “Company”) as of
December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee
of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material
respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal
Control - Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States)
(PCAOB), the consolidated financial statements and financial statement schedules as of and for the year ended December 31,
2017 of the Company and our report dated February 22, 2018 expressed an unqualified opinion on those financial statements
and financial statement schedules.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s
Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s
internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are
required to be independent with respect to the Company 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all
material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk
that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit
provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with authorizations of management and directors of the
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal
Control - Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States)
(PCAOB), the consolidated financial statements and financial statement schedule as of and for the year ended December 31,
2017 of the Company and our report dated February 22, 2018 expressed an unqualified opinion on those financial statements
and financial statement schedule.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s
Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s
internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are
required to be independent with respect to the Company 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all
material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk
that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit
provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with authorizations of management and directors of the
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Policy on Audit Committee Pre-Approval:
Idaho Power and the Audit Committee are committed to ensuring the independence of the independent registered public
accounting firm, both in fact and in appearance. In this regard, the Audit Committee has established and periodically reviews a
pre-approval policy for audit and non-audit services. For 2017 and 2016, all audit and non-audit services and all fees paid in
connection with those services were pre-approved by the Audit Committee.
In addition to the audits of Idaho Power’s consolidated financial statements, the independent public accounting firm may be
engaged to provide certain audit-related, tax, and other services. The Audit Committee must pre-approve all services performed
by the independent public accounting firm to assure that the provision of those services does not impair the public accounting
firm’s independence. The services that the Audit Committee will consider include: audit services such as attest services,
changes in the scope of the audit of the financial statements, and the issuance of comfort letters and consents in connection with
financings; audit-related services such as internal control reviews and assistance with internal control reporting requirements;
attest services related to financial reporting that are not required by statute or regulation, and accounting consultations and
audits related to proposed transactions and new or proposed accounting rules, standards and interpretations; and tax compliance
and planning services. Unless a type of service to be provided by the independent public accounting firm has received general
pre-approval, it will require specific pre-approval by the Audit Committee. In addition, any proposed services exceeding pre-
approved cost levels will require specific pre-approval by the Audit Committee. Under the pre-approval policy, the Audit
Committee has delegated to the Chairman of the Audit Committee pre-approval authority for proposed services; however, the
Chairman must report any pre-approval decisions to the Audit Committee at its next scheduled meeting.
Any request to engage the independent public accounting firm to provide a service which has not received general pre-approval
must be submitted as a written proposal to Idaho Power’s Chief Financial Officer with a copy to the General Counsel. The
request must include a detailed description of the service to be provided, the proposed fee, and the business reasons for
engaging the independent public accounting firm to provide the service. Upon approval by the Chief Financial Officer, the
General Counsel, and the independent public accounting firm that the proposed engagement complies with the terms of the pre-
approval policy and the applicable rules and regulations, the request will be presented to the Audit Committee or the Committee
Chairman, as the case may be, for pre-approval.
134
In determining whether to pre-approve the engagement of the independent public accounting firm, the Audit Committee or the
Committee Chairman, as the case may be, must consider, among other things, the pre-approval policy, applicable rules and
regulations, and whether the nature of the engagement and the related fees are consistent with the following principles:
• the independent public accounting firm cannot function in the role of management of Idaho Power; and
• the independent public accounting firm cannot audit its own work.
The pre-approval policy and separate supplements to the pre-approval policy describe the specific audit, audit related, tax, and
other services that have the general pre-approval of the Audit Committee. The term of any pre-approval is 12 months from the
date of pre-approval, unless the Audit Committee specifically provides for a different period. The Audit Committee will
periodically revise the list of pre-approved services, based on subsequent determinations.
