To Our 
Valued Shareholders:

2016 was a year of progress and success for your company. 
We continued our tradition of successfully executing our strategy 
by building on Idaho Power’s strong foundation of the past 
100 years as a fully integrated electric utility. We are pleased to 
be able to deliver solid 2016 results for you, our owners, and look 
forward to a productive future.

We had many notable successes in 2016: Improved earnings for 
a ninth consecutive year, progress on large capital expenditure 
projects, enhanced reliability for customers, record-high 
customer satisfaction survey scores and a well-received brand 
awareness campaign featuring stories of our environmental 
stewardship and company history. 

We are especially proud of our nine consecutive years of 
improved earnings, from 2008 through 2016. Our clear and 
succinct business strategy with established milestones and a 
focus on managing costs helps ensure we achieve fi nancial 
targets. Our steady common stock dividend growth is another, 
important way we add value for those who invest in IDACORP.

IDACORP continues to invest for the future in critical 
infrastructure, including major capital expenditures such 
as hydroelectric plant improvement programs and major 
reliability-related construction projects. Other marquee projects 
include environment controls at the Jim Bridger Power Plant, 
ongoing relicensing activities for the Hells Canyon Complex, 
and continued progress on the Boardman to Hemingway and 
Gateway West 500-kilovolt (kV) projects. 

 Our productive regulatory strategy continues to collect 
costs and earn a return for the company while maintaining 
fair rates for customers. It is a scenario that benefi ts 
everyone. And in 2016 we took another step to inprove our 
core business and improve effi  ciency when we began the 
process to join the Western Energy Imbalance Market, or 
EIM. We anticipate beginning our participation in 2018.

As always, serving our customers also remains a 
primary focus for Idaho Power. Delivering excellence 
and reliable service are at the core of what we do every 
day. Th  is commitment was refl ected once again in 
2016 as we saw record Customer Relationship Index 
(CRI) results. Th  is record-setting score refl ects the 
focus of employees’ eff orts on serving our customers 
and communities and responding to their needs. 
Residential, small business and large commercial and 
industrial segments all were higher at the end of 2016 
than they had been at the end of 2015.

Our optimism continues around customer and 
economic growth prospects; aff ordable, reliable, 
available electricity is a key driver of business 
development. We are seeing companies enter into and 
expand in various locations throughout our service 
area. Th  ese businesses are diverse, covering industries 
as varied as law enforcement, food processing and even 
brewing and industrial level beer production supplies. 
All see the value in fair-priced, reliable energy services 
that help run their businesses.

Recognition of our service area in prestigious media 
outlets from CNBC to Forbes to U.S. News and World 
Report shows that more and more people outside Idaho 
are learning what those of us who live here have known 
for a long time: It’s a great place to live and do business. 
In 2016 our state appeared on many lists touting the 
benefi ts of our diverse service area, including business 
friendliness, cost of doing business, and livability.

In 2016 IDACORP again saw improvement in 
our ranking in the Public Utilities Fortnightly 
Top 20 Financial Performers, to a tie for fi fth 
place. To identify the top 20, utilities are ranked 
on six fi nancial metrics. For the fi fth year in a 
row, IDACORP’S rank has continued to improve 
in the assessment of best energy companies, as 
announced in the magazine’s October issue. 

Th  e company was also the recipient of the prestigious 
Edison Electric Institute (EEI) Index Award in November 
at the 51st EEI Financial Conference. IDACORP was 
the top ranking small-cap company with a total return 
of 142 percent, and fi fth overall when combining our 
results with large-cap and mid-cap companies.

Our unparalleled employees are at the heart of 
our company culture of integrity and safety. Th  ese 
empowered, responsible employees demonstrate 
their commitment to serving our customers each 
and every day. Th  oughtfully considered development 
and succession planning at all levels helps ensure this 
tradition of excellence continues seamlessly into the 
future, and that the deep knowledge of management 
experience within our leadership team is passed on 
to the next generation. 

Developing and promoting an experienced leadership 
team is another part of our long-term strategy to 
ensure our company is well-positioned for a strong 
future. Th  is strategy includes robust participation from 
our Board of Directors, whose diverse backgrounds 
help ensure successful oversight of policies and solid 
business guidance. 

Long-term strategy is critical to why Idaho Power has 
been around for 100 years. In a fi tting acknowledgement 
of our centennial year, we were honored to ring the 
NYSE Closing Bell on Aug. 1, Idaho Power’s 100th 
anniversary. Th  is milestone event was a fi tting way 
to mark the principal contribution of IDACORP and 
Idaho Power shareowners through the past century.

We believe the outlook for IDACORP’S utility business 
remains strong. As always, we are focused on managing 
costs, growing revenue for our owners, improving our 
core business, and enhancing our company brand. Th  e 
completion of our hundredth year marks the beginning 
of a new chapter and the journey onward to the future, 
and we are ready for the opportunities that await.

In 2016, our centennial year, IDACORP’s primary subsidiary 
Idaho Power Company focused on three areas: improving 
our core business, growing revenues, and enhancing our 
brand. We believe the outlook for IDACORP’s utility business 
remains strong, and our continued focus on managing costs 
has yielded benefi ts for our owners and our customers.

2016 marked our ninth consecutive year of earnings growth. 
Customer growth of 1.8 percent increased general business 
revenue by $15.6 million in 2016 compared with 2015. 
Net income increased $3.6 million from 2015 to 2016.

Once again we were able to preserve tax credits under our Idaho 
regulatory stipulation for potential use in future years. Our eff orts 
continue to be targeted on managing costs and growing revenues 
with the goal to continue to preserve credits for future years. 
Th  e full $45 million of credits is currently available for earnings 
support through 2019.

We fi nished the year having incurred just under $352 million of 
operations and maintenance (O&M) expenses, putting us near 
$350 million for the fi fth year in a row. We are pleased with the 
results of our eff orts to control costs over the past several years.

2016 ended with earnings of $3.94 per diluted share, and we 
initiated earnings guidance for the full year 2017 in the range 
of $3.90 to $4.05 per diluted share.

Dividend Growth
During 2016 IDACORP continued to make 
meaningful progress toward the upper end of its 
target dividend payout ratio of between 50 and 60 
percent of sustainable IDACORP earnings.

Idaho Power’s hydroelectric facilities 
comprise nearly half of our nameplate 
generation capacity. Customers are served 
by a series of 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.

Idaho Power has been steadfastly working 
to renew our long-term federal license 
for the three-dam Hells Canyon Complex, 
our largest hydroelectric generation source. 
At the end of 2016, we fi led with the Idaho 
Public Utilities Commission (IPUC) for a 
prudency review of costs spent through 
December 2015 in the relicensing eff ort. 
As of February 23, 2017, the IPUC currently 
authorizes Idaho Power to include in its 
Idaho jurisdiction rates approximately 
$10.7 million annually of Allowance for 
Funds Used During Construction (AFUDC) 
relating to the relicensing project. 
Collecting these amounts now reduces 
the amount needed to be collected in 
the future when the relicensing costs are 
approved for recovery in base rates.

ENERGY 
DELIVERED TO 
CUSTOMERS

*Idaho Power sells the Renewable Energy Certifi cates (RECs) that it receives in association with this energy, with 

proceeds benefi ting retail customers. Because Idaho Power does not own the RECs for the other qualifi ed renewable 
resources included in our Resource Portfolio Fuel Mix, Idaho Power cannot and does not represent that electricity 
produced by this fuel mix is being delivered to its retail customers.

P A G E

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 megawatt (MW) nameplate capacity. As 
of December 31, 2016, Idaho Power had contracts to 
purchase energy from 117 on-line CSPP projects, 12 
additional projects expected to come on-line in 2017, 
and three projects expected to come on-line in 2019. 

In the fall, Idaho Power began the Community Solar 
Pilot Program in response to increased interest in 
renewable and community-based energy. Customers 
in our Idaho service area now have the option of 
signing up to purchase a portion of the electricity 
generated by a 500-kilowatt (kW) photovoltaic solar 
array to be built in Boise. Once the project is built and 
generating power, participants will receive a monthly 
bill credit for their portion of the output. 

Social and Environmental Responsibility
Idaho Power has further extended and expanded 
its CO2 emissions intensity reduction goal. We are 
seeking to reduce our company-owned resource 
portfolio average CO2 emissions intensity to 
15–20 percent below 2005 levels for the 2010–2017 
timeframe. In 2016 Idaho Power exceeded the CO2 
emissions-intensity reduction goals.

2017 Integrated Resource Plan

Idaho Power plans for infrastructure that will 
support anticipated growth and allow us to 
continue to provide reliable, fair-priced electric 
power to our customers.

Every two years Idaho Power updates its Integrated 
Resource Plan, or IRP, with the participation of the 
IRP Advisory Council (IRPAC). 

Th  e company is in the midst of preparing its 2017 
IRP update. In September 2016 the IRPAC, which 
comprises representatives from various stakeholder 
groups, began the process of working with the 
company to develop the next IRP. We expect to fi le 
the document at the end of June 2017.

Many thanks to Northwest Lineman College and Alan Drew for use of the vintage photographs in this story.

Then... In 1892, an electric trolley service connected 
downtown Boise to Hyde Park. Servicing the line was 
dangerous for these linemen with limited safety gear. 

500-kV Transmission Projects

In October 2016 the Bureau of Land Management 
(BLM) released its fi nal Supplemental 
Environmental Impact Statement for Gateway 
West segments 8 and 9 located in southwestern 
Idaho. Th  e BLM released its record of decision for 
the remaining two line segments in January 2017. 
Gateway West is a proposed 500-kV, 1,000-mile 
transmission line jointly proposed by Idaho Power 
and Rocky Mountain Power. 

Boardman to Hemingway is a proposed 
300-mile, 500-kV transmission line that will 
run from southern Idaho to northeast Oregon. 
Th  e BLM issued a fi nal Environmental Impact 
Statement for the project on Nov. 25, 2016. We 
expect a Record of Decision from the BLM in 2017. 

Now... Today, safety comes fi rst at 
Idaho Power. Our linemen are protected 
with hard hats, rubber gloves and sleeves, 
fl ame-retardant clothing, safety glasses, 
bucket trucks and fall-protection gear.

Low Rates
Decisions made decades ago have led to the low-cost 
electricity Idaho Power customers enjoy today. In 
pursuit of our goal of advancing a purposeful regulatory 
strategy, Idaho Power focuses on timely recovery of 
costs through fi lings with regulators, working to deploy 
innovative regulatory mechanisms, and on the prudent 
management of expenses and investments.

We are running our business in a manner that will 
continue to earn a fair return for shareholders while 
keeping customer rates relatively low. We haven’t 
changed base rates since 2012, and in 2017 we will 
continue to assess 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 2015 regulatory settlement. We will continue 
to be diligent in managing costs and growing revenues 
with the goal to save credits for use in future years.

Th  e company did not use any additional ADITC 
amortization for the full year of 2016. Th  is preserves 
the full $45 million of credits for future years.

P A G E

Regulatory Mechanisms
To address the volatility of power supply costs, Idaho 
Power’s Power Cost Adjustment (PCA) mechanisms in 
Idaho and Oregon allow the company 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.

In 2016 increased costs associated with  power 
purchases from PURPA projects were a main factor 
contributing to the approved $17.3 million increase 
in Idaho. 

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 2016 the FCA 
was an approved $11.2 million increase.

Depreciation Filings
In Fall 2016, Idaho Power requested from the 
public utilities commissions in Idaho and Oregon 
an increase in customer rates to refl ect an 
accelerated depreciable life for the Valmy power 
plant. Currently, the depreciable life for Valmy 
is based on a depreciation schedule that ends in 
2031 for Unit 1 and 2035 for Unit 2. Th  e proposed 
depreciation schedule would move the date of 
full depreciation up to 2025 for both units.  

Idaho Power’s 2016 assessment of Valmy concluded 
it may not benefi t customers from an economic 
and an electric reliability perspective to operate 
the facility beyond 2025.

In addition, Idaho Power fi led a depreciation study 
in Idaho and Oregon to adjust its depreciation rates 
to match longevity it is currently experiencing for 
the balance of utility plant equipment. 

Energy Imbalance Market
On March 31, Idaho Power signed an agreement 
to participate in the Western EIM beginning in 
April 2018 contingent on 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, within 
the hour, of a larger and more diverse pool of 
resources, to integrate intermittent power from 
renewable generation resources more eff ectively 
and to enhance reliability.

In February 2017 the IPUC approved a deferred 
accounting treatment related to joining the EIM. 

Then... In the 1930s, Idaho Power’s marketing efforts 
continued to target the home — in particular, the woman 
of the home — to meet sales goals. New advertising 
recognized customers’ fi nancial challenges and marketed 
electric living as “cheap.”

Now... Today, Idaho Power provides a robust suite 
of energy effi ciency options that help customers choose 
how they use electricity. Our Fixed Cost Adjustment 
ensures Idaho Power still recovers fi xed costs.

P A G E

Then... In 1916, Idaho Power’s facilities 
generated only 20,340 kW and served only 
18,000 customers. But demand for electricity 
grew dramatically.

Now... Now, Idaho Power serves 
approximately 535,000 customers and has 
facilities that generate 3,600,000 kW. And we 
see demand for electricity continue to grow 
throughout our service area.

Growth and Customers
In recent years, Idaho Power has seen growth in the 
number of customers in its service area—in 2016 
its customer count grew by 1.8 percent—and in 
employment in Idaho Power’s service area, which 
grew by approximately 3.5 percent in 2016. It’s worth 
noting that we tied our 2009 record winter peak 
demand of 2,527 MW in January 2017.

Customer growth in Idaho Power’s service area 
continues to positively impact revenues.

Economic Development Activity in Service Area 
Energy that is aff ordable and available has long been 
one of the major reasons for the region’s long-term 
economic growth.

Idaho Power has in recent years supported State 
of Idaho coordinated eff orts to promote economic 
development with an emphasis on attracting 
industrial and commercial customers to its service 
area. We continue to see businesses relocate and 
expand in southern Idaho, including Chobani, 
Clif Bar, Albertsons, Great Western Malting  and 
Sorrento Lactalis.

Then… In the early 1900s many 
utilities did not meter electric service for 
residential customers because the only 
available electric devices were lights. 
To calculate a bill, they counted light 
bulbs in the home. As electric appliances 
became affordable, utilities installed 
meters and began reading them for 
billing. Early meters had a maximum 
rating of 10 amps; by the 1940s meters 
were rated for 100 amps and by the 
1970s, 200-amp meters were the norm. 

Now… Prior to our Advanced 
Metering Infrastructure project, most 
meters were read manually each 
month. With the modern meters, 
we remotely record hourly data 
along with a peak demand reading. 
Customers don’t have to wait for their 
bill to see how much energy they use; 
they can track it on our website. And 
today, we are seeing more customers 
with 400-amp service and larger.

Volunteerism
Together with our families, 
friends and retirees, Idaho Power 
volunteers made signifi cant 
contributions to the communities 
where we live and work in 2016. 
We mentored students, assisted at 
STEM and science competitions, 
raked yards, painted homes, 
sorted food, dug trails and more. 

In 2016, to build on our legacy 
of volunteerism, the company 
launched the Idaho Power 
Employee Volunteer Site to 
help connect employees to 
company-sponsored volunteer 
opportunities. Th  is new tool helps 
our employees demonstrate their 
commitment to communities 
off  the job as well as on.

2016 also brought an important 
acknowledgement of Idaho Power 
from the healthcare community: 
Th  e company received both the 
prestigious Luke Award from St. 
Luke’s Children’s Hospital in 
Boise and the 2016 Distinguished 
Citizen Award from Saint 
Alphonsus Hospital, also in Boise. 
Idaho Power has been an integral 
partner of the hospitals for many 
years, supporting campaigns, 
events and programs to enhance 
and expand healthcare services. 
Many Idaho Power employees, 
including our executives, have 
supported St. Luke’s and Saint 
Alphonsus with time, talent and 
treasure over the years.

The past year was one fi lled with highlights for 
your utility. We executed on business optimization 
initiatives, focusing on improving operations and 
controlling costs. We achieved the best year of 
performance for electric system reliability since 2006, 
when we fi rst began tracking reliability. We reached 
the highest rolling 12-month internal measure of 
customer satisfaction ever recorded by 
the company. And we improved Idaho Power’s 
ranking from 11 to 5 (tied) in the annual Top 20 
Financial Performers list published by Public 
Utilities Fortnightly. And we couldn’t have done any 
of it without the 2,000 dedicated men and women 
who run your utility every day. 

Th  ese employees are key to your company making 
progress on three core focuses for 2017—improving 
Idaho Power’s core business, growing revenues, and 
enhancing the brand and positioning the company 
for the future.

Then... Early work areas were indicative of the 
economic times and Idaho Power’s “startup” period. 

Now... Craftspeople, such as these employees of 
the Idaho Power Mechanical & Engineering Shop, 
work in safe, clean, modern conditions with 
state-of-the-art equipment.

P A G E

In the next year and beyond we will continue to 
enhance and promote Idaho Power’s safety culture, 
grow fi nancial strength by supporting business 
development in our service area while actively 
managing costs, and pursue responsible investments 
that address customer growth while seeking to 
improve reliability, enhance Idaho Power customers’ 
experience, increase shareholder value, and manage 
environmental impacts.

Our values of safety, integrity, and respect 
are strong. Our focus on the future is clear. 
And we value your continued investment 
in IDACORP now and moving forward.

In addition to the historical information contained in this report, this report contains (and oral communications made by 
IDACORP, Inc. and Idaho Power Company may contain) statements that relate to future events and expectations, such as 
statements regarding projected or future financial performance, cash flows, capital expenditures, dividends, capital structure or 
ratios, strategic goals, challenges, objectives, and plans for future operations.  Such statements constitute forward-looking 
statements within the meaning of the Private Securities Litigation Reform Act of 1995.  Any statements that express, or involve 
discussions as to, expectations, beliefs, plans, objectives, assumptions, future events, or performance, often, but not always, 
through the use of words or phrases such as "anticipates," "believes," "estimates," "expects," "guidance," "intends," "potential," 
"plans," "predicts," "projects," "may result," "may continue," or similar expressions, are not statements of historical facts and 
may be forward-looking.  Forward-looking statements are not guarantees of future performance and involve estimates, 
assumptions, risks, and uncertainties. Actual results, performance, or outcomes may differ materially from the results discussed 
in the statements.  In addition to any assumptions and other factors and matters referred to specifically in connection with such 
forward-looking statements, factors that could cause actual results or outcomes to differ materially from those contained in 
forward-looking statements include those factors set forth in Part I, Item 1A - “Risk Factors” and Part II, Item 7 - 
“Management’s Discussion and Analysis of Financial Condition and Results of Operations" of this report, as well as in 
subsequent reports filed by IDACORP and Idaho Power with the U.S. Securities and Exchange Commission, and the following 
important factors:

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, 2016, IDACORP had 2,008 full-time employees, 1,999 of 
whom were employed by Idaho Power, and 12 part-time employees, 10 of whom were employed by Idaho Power.

IDACORP’s other subsidiaries include IDACORP Financial Services, Inc. (IFS), an investor in affordable housing and other 
real estate investments; 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); and IDACORP Energy Services Co. 
(IESCo), the successor to IDACORP Energy L.P., a marketer of energy commodities that wound down operations in 2003.  

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 approximately 535,000 general business customers in southern Idaho and 
eastern Oregon as of December 31, 2016.  Over 444,000 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 71 cities in 
Idaho and 9 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 one 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.

Business Strategy

IDACORP’s business strategy emphasizes Idaho Power as IDACORP’s core business, as Idaho Power's utility operations are 
the primary driver of IDACORP's operating results.  Idaho Power's three-part strategy can be summarized as follows:

•  Responsible Planning:  Idaho Power’s planning process is intended to ensure adequate generation, transmission, and 
distribution resources to meet anticipated population growth and increasing electricity demand.  This planning process 
integrates Idaho Power’s regulatory strategy and financial planning, including the consideration of regional economic 
development in the communities Idaho Power serves.

8

 
 
 
 
 
 
 
 
•  Responsible Development and Protection of Resources:  Idaho Power’s business strategy includes the development 
and protection of generation, transmission, distribution, and associated infrastructure, and stewardship of the natural 
resources upon which Idaho Power and the communities it serves depend.  Additionally, the strategy considers 
workforce planning and employee development and retention related to these strategic elements.

•  Responsible Energy Use:  Idaho Power's business strategy includes energy efficiency and demand response programs 
and preparation for potential carbon and renewable portfolio standards legislation.  The strategy also includes targeted 
reductions relating to carbon emission intensity and public reporting of these reductions, as well as operating Idaho 
Power's system in a manner that extracts additional value through changes in fuel mix and generation.

Idaho Power’s business strategy seeks to balance the interests of owners, customers, employees, and other stakeholders while 
maintaining the company’s financial stability and flexibility.  Idaho Power's  three-part business strategy includes three core 
focuses—improving its core business, growing revenues, and enhancing the brand and positioning the company for the future.  
IDACORP continues to focus on its core business and its goal of generating returns for its shareholders and long-term 
shareholder value. 

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, are 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 
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 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 alter demand 
for Idaho Power's electric energy.  Idaho Power also competes with fuel distribution companies 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, has 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 
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 3,407 MW, set on July 2, 2013, at which time Idaho Power had deployed 30 MW of demand response programs to mitigate 
the load demand.  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.  Idaho Power's peak demand during 2016 was 3,299 MW.  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 1,709 MW and annual generation of approximately 
8.5 million Megawatt-hours (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.  

During low water years, when stream flows into Idaho Power’s hydroelectric projects are reduced, Idaho Power’s hydroelectric 
generation is reduced.  The result is a greater reliance on other generation resources and power purchases.  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.  The Northwest River Forecast Center of 
the National Oceanic Atmospheric Administration reported that the 2016 April through July inflow volume into Brownlee 
Reservoir (the uppermost reservoir of Idaho Power's Hells Canyon Complex) was only 73 percent of normal.  By comparison, 
the 2015 April through July Brownlee Reservoir inflow was 46 percent of normal.  For 2017, Idaho Power estimates annual 
generation from its hydroelectric facilities to be between 7.0 million MWh and 9.0 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 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 2017 from the Black 
Butte Coal Company’s Black Butte mine located near the Jim Bridger plant.  This contract supplements the BCC deliveries and 
provides another coal supply to operate 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.  Idaho Power's existing coal inventory at the North Valmy plant is 
expected to meet Idaho Power's projected coal requirements at the plant through at least 2017.  Idaho Power expects to be able 
to obtain future coal requirements through coal supply contracts.  In October and November 2016, Idaho Power filed 
applications with the IPUC and OPUC, respectively, requesting authorization to accelerate depreciation for the North Valmy 
power plant, to allow the plant to be fully depreciated by December 31, 2025.  For additional information on the filings, see the 

12

 
 
 
 
 
 
 
 
 
 
 
“Regulatory Matters” section of Part II, Item 7 – “Management’s Discussion and Analysis of Financial Condition and Results of 
Operations” (MD&A).

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 2017.  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, 2016, 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 2018.  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.

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 2016 and 2015, Idaho Power 
purchased 2.0 million MWh and 1.8 million MWh of power through wholesale market purchases at an average cost of $42.04 
per MWh and $49.57 per MWh, respectively.  During 2016 and 2015, Idaho Power sold 1.2 million MWh and 1.3 million 
MWh of power in wholesale market sales, with an average price of $21.25 per MWh and $24.63 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 is through 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 is through 2033.

PURPA Power Purchase Contracts:  Idaho Power purchases power from PURPA projects as mandated by federal law.  As of 
December 31, 2016, Idaho Power had contracts with on-line PURPA-related projects with a total of 945 MW of nameplate 
generation capacity, with an additional 178 MW nameplate capacity of projects projected to be on-line in 2017 and an 
additional 9 MW expected to be added in 2019.  The power purchase contracts for these projects have original contract terms 

13

 
 
 
 
 
 
 
 
 
 
 
ranging from one to 35 years.  The expense and volume of PURPA project power purchases during the last three years is

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. 

•  The IPUC issued an order in August 2015 that revised the standard PURPA power purchase contract term for new 

contracts to 2 years from the previously required 20-year term. 

•  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.

•  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. 

Idaho Power, as well as other affected electric utilities, are engaged in proceedings at the OPUC relating to PURPA contracts.  
The OPUC issued orders in 2016 pertaining to contract term, project eligibility for standard rates, and standard avoided cost 
calculations. Other ongoing OPUC proceedings relate to, among other issues, the prices paid for energy purchased from PURPA 
projects and solar integration charges.  Refer to Part II - Item 7 - MD&A - "Regulatory Matters - Renewable and Other Energy 
Contracts" for a summary of those proceedings.

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 a new 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, in April 2016, 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 the spring of 2018. 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 requests recovery of 

14

 
 
 
 
 
 
 
 
 
 
the costs and the deferral balance or the end of 2018.  Recovery of deferred costs will be addressed in a future IPUC 
proceeding.

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 2015.  Idaho Power is presently preparing the 2017 IRP, which Idaho 
Power anticipates filing in June 2017.  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: 

• 

• 
• 
• 

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 expects to use 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 

15

 
 
 
 
 
 
 
 
     
 
 
 
 
development of resources, such as new generation plants or transmission infrastructure, to serve those loads.

2017 IRP

2015 IRP

2013 IRP

The 2015 IRP identified a preferred resource portfolio, which included the completion of the Boardman-to-Hemingway 500-kV 
transmission line and the potential early retirement of the North Valmy power plant, both in 2025, with no other new resource 
needs prior to 2025.  The near-term action plan also included commencement of an economic evaluation of environmental 
control retrofits for units 1 and 2 at the Jim Bridger power plant.  However, as noted in the 2015 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, implementation of the U.S. Environmental Protection 
Agency's (EPA) rules under Section 111(d) of the Clean Air Act (CAA), 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 22 programs.  These energy efficiency programs target energy savings across the entire year, while the demand 
response programs target system demand reduction in the summer.  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 heating, ventilation and cooling equipment, 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 2016, Idaho Power’s energy efficiency programs reduced energy usage by approximately 142,000 MWh.  For 2016, Idaho 
Power had a demand response available capacity of approximately 392 MW.  In 2016 and 2015, Idaho Power expended 
approximately $43 million and $39 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.

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, especially given the additional regulations proposed and issued 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

Total operations and maintenance

Idaho Power anticipates that finalization and implementation of a number of federal and state rulemakings and other 
proceedings addressing, among other things, greenhouse gases and endangered species, could result in substantially increased 
operating and compliance costs in addition to the amounts set forth above, but Idaho Power is unable to estimate those costs 
given the uncertainty associated with potential future regulations.  Idaho Power would seek to recover those increased costs 
through the ratemaking process. 

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 North Valmy plant as a coal-fired resource.  Idaho 
Power filed an application with the IPUC and OPUC in October and November 2016, respectively, requesting accelerated 
depreciation of the North Valmy plant in connection with the potential early closure of the plant.  Idaho Power is also assessing 
the economic desirability of potential future investments in additional selective catalytic reduction technology at the Jim 
Bridger coal-fired 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 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.  

Idaho Power's estimated historic CO2 emissions intensity from its generation facilities, as submitted to the Carbon Disclosure 
Project, was as follows:

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 and in other reports the companies file with the SEC, should be considered carefully when making 
any investment decisions relating to IDACORP or Idaho Power.  

If state public utility commissions or the Federal Energy Regulatory Commission authorize retail or transmission customer 
rates that under-collect or delay the collection through customer rates of the amount Idaho Power needs to cover costs and 
earn a reasonable rate of return, IDACORP's and Idaho Power's financial condition and results of operations may 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 IDACORP’s and Idaho Power’s business, results of operations, 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, and 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.  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.  Denial or probable 
denial of recovery by regulators may cause Idaho Power to record an impairment of its assets.  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 compensation expenses.  Adverse outcomes in regulatory proceedings or significant regulatory lag 
may 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 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, 

19

 
 
 
 
 
 
 
 
 
 
 
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.  In recent years, the volatility in power 
supply costs has been 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, weak economic conditions, 
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, and economic 
conditions.  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 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.  If customers choose to generate their own energy or replace 
electric power for heating with natural gas, demand for Idaho Power's energy may decline and adversely impact the 
affordability of our 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 954 kWh in 2016.  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 kWh 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, 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, including as a result of climate change.  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 

20

 
 
 
 
 
 
 
 
 
and the timing and amount of precipitation, among other factors, 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.  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. 

Some scientists have predicted that increasing concentrations of GHG in the earth's atmosphere may produce climate changes 
that have significant physical effects, such as increased frequency and severity of storms, droughts, floods, and other extreme 
weather events.  If such effects were to occur, Idaho Power's operations could be adversely affected and its cost of providing 
service could increase.  Extreme weather events and their associated impacts (such as fires, high winds, and snow loading) can 
damage generation facilities and disrupt transmission and distribution systems, causing service interruptions and extended 
outages through downed transmission and distribution lines, increasing supply chain costs and limiting Idaho Power's ability to 
meet customer energy demand.  Sustained drought conditions are likely to decrease power generation from hydroelectric plants.  
The effect of the failure of Idaho Power's facilities to operate as planned under extreme weather conditions is particularly 
burdensome during peak demand periods, such as hot summer days.  Damage and disruption in generation, transmission, and 
distribution systems due to weather-related factors also often increases O&M expenses.  Costs incurred as a result of such 
events might not be recovered through customer rates if the costs incurred are greater than those allowed for recovery by 
regulators, and the costs of repair and replacing infrastructure or liability for personal injury or property damage may not be 
covered in full by insurance. 

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 tax 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.  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 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 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; 
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 

21

 
 
 
 
 
 
 
 
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 as a result of the 2016 U.S. presidential and congressional 
elections may have a material adverse effect on IDACORP’s and Idaho Power’s business in the future.  The recent 
presidential and congressional elections in the United States could result in significant changes in, and uncertainty with respect 
to, legislation, regulation, and government policy. While it is not possible to predict whether and when any such changes will 
occur, they could significantly impact IDACORP’s and Idaho Power’s businesses and the electric utility industry. Specific 
legislative and regulatory proposals discussed during and after the election that could have a material impact on IDACORP and 
Idaho Power include, but are not limited to, reform of the federal tax code; infrastructure renewal programs; and modifications 
to public company reporting requirements and environmental regulation.  Further, the proposals 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 unable to predict whether reform discussions 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.

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.  A number of federal, state, and local 
environmental statutes, rules, and regulations relating to air and water quality, natural resources, renewable energy certificates, 
and health and safety are applicable to IDACORP's and Idaho Power's operations.  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.  For instance, Idaho Power recently installed environmental control apparatus in two units of its co-owned Jim 
Bridger power plant at a cost of $100 million, excluding AFUDC. Due to uncertainties resulting from pending environmental 
regulation and the substantial estimated cost of installing similar controls on the remaining two units, Idaho Power is assessing 
whether to move forward with the remaining installations. 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 to obtain or maintain all environmental regulatory approvals 
necessary for operation of its existing infrastructure or construction of new infrastructure.  

22

 
 
 
 
 
 
 
 
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.  For example, in 2013, the IPUC declined to approve Idaho Power's application requesting a binding commitment to 
provide rate base treatment for Idaho Power's estimated share of the capital investment in environmental control upgrades at the 
Jim Bridger power plant, instead reserving the prudence determination (and thus ratemaking treatment) for subsequent 
proceedings.  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, such as the EPA’s proposed 
regulations to reduce CO2 emissions as described in Part II - Item 7 - "Management's Discussion and Analysis of Financial 
Condition and Results of Operations - Environmental Matters" in this report.  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 2016, 53 percent of Idaho Power's electric power generation was from hydroelectric facilities.  
Because of 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 particularly 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.  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 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 influenced by factors impacting supply 

23

 
 
 
 
 
 
 
 
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 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, 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, or not being able to access lower cost sources of electric energy.   

Accidents, electrical contacts, fires, explosions, catastrophic failures, general system damage or dysfunction, and other 
unplanned events related to Idaho Power's infrastructure would increase repair costs and may expose Idaho Power to claims for 
personal injury and property damage, interest, and attorneys' fees.  Fires alleged to have been caused by Idaho Power's system 
could also expose Idaho Power to claims for fire suppression costs and claims related to fires 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 the terms and limitations of the available policies and may not be sufficient to cover Idaho Power’s ultimate liability.  
Idaho Power is also subject to the risk that insurers and other parties will dispute, or be unable to perform, their obligations to 
Idaho Power with respect to such claims, which could have an adverse effect on IDACORP's and Idaho Power's financial 
condition and results of operations.       

Volatility 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.  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 obligation of the participating 

24

 
 
 
 
 
 
 
 
banks to make those loans and issue letters of credit is subject to specified conditions.  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.  Without additional state regulatory 
approval, as of the date of this report the aggregate amount of short-term borrowings by Idaho Power at any one time 
outstanding may not exceed $450 million.  Also, 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.  Failure to maintain these 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 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- 
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 

25

 
 
 
 
 
 
 
 
 
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 imposition of penalties 
on Idaho Power for its actual or alleged failure to comply with reliability and security requirements could 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.  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 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.   

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, 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 

26

 
 
 
 
 
 
 
 
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 2017 and in the near-term.  At December 31, 2016, 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 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 a 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 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.  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.  The loss of data could result in violations of privacy and other laws, financial loss to Idaho Power or to its 
customers, customer dissatisfaction, and significant litigation exposure, all of which could materially affect Idaho Power's 
financial condition and results of operations.

Changes in 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 about the 
application of the law when determining the provision for taxes.  Amounts of 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, tax settlements, as well as state regulatory mechanisms with tax-related provisions (such 

27

 
 
 
 
 
 
 
 
 
 
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 tax 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 tax benefits 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 flow-through accounting as 
described in Note 1 - "Summary of Significant Accounting Policies" to the consolidated financial statements included in this 
report, and potential changes in tax laws or interpretations may impact IDACORP's and Idaho Power's income taxes and 
reporting obligations differently than other companies.

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.

ITEM 1B.  UNRESOLVED STAFF COMMENTS

ITEM 2.  PROPERTIES

Idaho Power's properties consist of the physical assets necessary to support its utility operations, which include generation, 
transmission, and distribution facilities, as well as coal assets that support one of its coal-fired generation plants.  In addition to 
these physical assets, Idaho Power has rights-of-way and water rights that enable it to use its facilities.  Idaho Power’s system is 
comprised of 17 hydroelectric generating plants located in southern Idaho and eastern Oregon, three natural gas-fired plants in 
southern Idaho, and interests in three coal-fired steam electric generating plants located in Wyoming, Nevada, and Oregon.  As 
of December 31, 2016, the system also includes approximately 4,861 pole-miles of high-voltage transmission lines, 24 step-up 
transmission substations located at power plants, 24 transmission substations, 10 switching stations, 223 energized distribution 
substations (excluding mobile substations and dispatch centers), and approximately 27,263 pole-miles of distribution lines.

Idaho Power holds FERC licenses for all of its hydroelectric projects that are subject to federal licensing.  Relicensing of Idaho 
Power’s hydroelectric projects is discussed in Item 7 - MD&A – "Regulatory Matters – Relicensing of Hydroelectric Projects.”

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).  On February 17, 2017, 
there were 10,029 holders of record of IDACORP common stock and the closing stock price was $80.00 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 $105 million, $97 million, and $89 million in 2016, 2015, and 2014, 
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 
2016 were 53 percent of actual 2016 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.

ITEM 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
AND RESULTS OF OPERATIONS

In Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) in this report, the general 
financial condition and results of operations for IDACORP and its subsidiaries and Idaho Power and its subsidiary are 
discussed.  While reading the MD&A, please refer to the accompanying consolidated financial statements of IDACORP and 
Idaho Power.  Also refer to "Cautionary Note Regarding Forward-Looking Statements" and Part I - Item 1A - "Risk Factors" in 
this report for important information regarding forward-looking statements made in this MD&A and elsewhere in this report.

INTRODUCTION

IDACORP is a holding company formed in 1998 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 IPUC, OPUC, and 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 experiences its highest retail energy sales during the summer 
irrigation and cooling season, with a lower peak in the winter that generally results from heating demand.  Idaho Power’s rates 
are established through regulatory proceedings that affect its ability to recover its costs and the potential to earn a return on its 
investment. 

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 subsidiaries include IFS, an investor in affordable housing and other real 
estate investments; Ida-West Energy Company, an operator of small hydroelectric generation projects that satisfy the 
requirements of the PURPA; and IDACORP Energy Services Co. (IESCo), which is the former limited partner of, and 
successor by merger to, IDACORP Energy L.P., a marketer of energy commodities that wound down operations in 2003.  

EXECUTIVE OVERVIEW

Management's Outlook

Customer growth in Idaho Power's service area continues to benefit Idaho Power's revenues.  To encourage continued 
responsible and sustainable growth, and as part of its planning for the future, Idaho Power actively participates in and supports 
state and local economic development initiatives.  At the same time that Idaho Power pursues customer growth, it must also 
plan for that growth.  Idaho Power plans for infrastructure that will support anticipated growth and allow it to continue to 
provide reliable, fair-priced electric power to its customers.  To that end, Idaho Power's noteworthy capital projects include the 
replacement of aging assets, upgrades to generation plants, a multi-year plan for replacement of underground conductor, 
ongoing system upgrades, and continued permitting of the Boardman-to-Hemingway and Gateway West 500-kV transmission 
lines.  As of the date of this report, Idaho Power estimates total capital expenditures of approximately $1.5 billion over the next 
five years.

Idaho Power operates within what it believes to be a constructive regulatory framework, achieved through general rate cases, 
subject-specific rate filings, tariff riders, and cost recovery mechanisms that share risks and benefits with Idaho Power's 
customers.  To complement the regulatory framework, Idaho Power focuses on controlling power supply, operating, 
maintenance, and capital costs through process review and improvement initiatives, and by empowering employees to identify 
new means to reduce costs, increase efficiencies, and enhance individual and enterprise performance for the benefit of 
IDACORP's shareholders, Idaho Power's customers, and other stakeholders.  Idaho Power's base rates were most recently reset 
in 2012 through general rate cases in Idaho and Oregon.  During 2017, Idaho Power will continue to assess the need to file a 
general rate case to reset base rates in the coming years in Idaho or Oregon.

Separately, during 2016, IDACORP continued to make meaningful progress toward its target dividend payout ratio of between 
50 and 60 percent of sustainable IDACORP earnings, which expanded on the progress made in previous years.  From 2012 
through 2016, IDACORP's board of directors approved a collective 83 percent increase in the quarterly dividend, from $0.30 to 
$0.55 per share.

2016 Accomplishments and 2017 Initiatives

IDACORP’s business strategy emphasizes Idaho Power as IDACORP’s core business.  For the past several years, Idaho Power 
has been executing its three-part strategy of responsible planning, responsible development and protection of resources, and 
responsible energy use.  This strategy is described in Part I, Item 1 - "Business" of this report.  Examples of IDACORP's and 
Idaho Power's achievements and recognitions during 2016 under its three-part business strategy include:

• 
• 

IDACORP achieved net income growth for a ninth consecutive year;
IDACORP provided a 19 percent cumulative total shareholder return over the past three years, including share price 
appreciation and dividends paid, ranking in the 88th percentile among peers;
increased IDACORP's quarterly common stock dividend from $0.51 per share to $0.55 per share; 
produced the best year of performance for Idaho Power's electric system reliability since formal measurement began in 
2006;
• 
executed on business optimization initiatives, focusing on improving operations and controlling expenditures;
•  made continued progress toward the permitting of the Boardman-to-Hemingway and Gateway West 500-kV 

• 
•

customers’ experience, increasing shareholder value, and managing carbon impacts; and
integrate new renewable generation resources into Idaho Power’s grid and continue progress toward participation in 
the Western EIM, anticipated to begin in the spring of 2018, which is expected to capture intra-hour market 
opportunities to help achieve greater reliability and improve system dispatch.

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 later in this MD&A.  To provide context for the discussion elsewhere in this report, 
some of the more notable factors include the following: 

•  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).  
During 2017, 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 2016, its customer count grew by 1.8 percent—and in 
employment in Idaho Power's service area, which grew by approximately 3.5 percent in 2016 based on Idaho 
Department of Labor preliminary December 2016 data.  Idaho Power expects its number of customers to continue to 

34

 
 
 
 
 
 
 
 
 
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 August 2016, Idaho Power began preparing its 2017 IRP, Idaho Power's long-term forecast of loads and resources.  
The load forecast assumptions Idaho Power expects to use 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 Hells Canyon Complex (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 
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 coal and natural gas 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 

35

 
 
 
 
 
 
 
 
  
 
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.  

•  Changes in legislation, regulation, and government policy as a result of the 2016 U.S. presidential and 

congressional elections:  The recent presidential and congressional elections in the United States could result in 
significant changes in, and uncertainty with respect to, legislation, regulation, and government policy. While it is 
uncertain whether and when any such changes will occur, they could significantly impact IDACORP’s and Idaho 
Power’s businesses and the electric utility industry. Specific legislative and regulatory proposals discussed during and 
after the election that could have a material impact on IDACORP and Idaho Power include, but are not limited to, 
reform of the federal tax code; infrastructure renewal programs; and modifications to public company reporting 
requirements and environmental regulation.

•  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 and the North American Electric Reliability Corporation.  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.  For instance, the Boardman coal-fired power plant, in which Idaho 
Power owns a 10-percent interest, is scheduled to cease coal-fired operations by the end of 2020, a decision driven in 
large part by the substantial cost of environmental controls required by existing regulations.  Similarly, Idaho Power is 
assessing the early closure of the North Valmy coal-fired power plant, of which Idaho Power owns a 50-percent 
interest, and in October and November 2016 filed applications with the IPUC and OPUC, respectively, requesting 
accelerated depreciation of the facility.  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.

IDACORP's 2016 net income increased $3.6 million compared with 2015.  While Idaho Power's 2016 net income was 
relatively flat, decreasing $1.7 million compared with 2015, net income from other subsidiaries increased IDACORP's net 
income by $5.3 million.  

Continued customer growth at Idaho Power increased operating income by $11.2 million, which was more than offset by a 
$14.7 million decrease from lower usage per customer in 2016 compared with 2015.  Winter temperatures in 2016 were slightly 
colder than 2015, but milder summer temperatures in 2016 led to lower sales volumes, revenues, and operating income.  Other 
operating and maintenance (O&M) expenses were $9.7 million higher in 2016 compared with 2015, largely related to higher 
variable labor-related costs. 

During 2015, Idaho Power recorded a total of $3.2 million as a provision against current revenue related to the October 2014 
Idaho regulatory settlement stipulation that required sharing with Idaho customers of a portion of 2015 earnings that exceeded 
10.0 percent.  During 2016, no such sharing provision was recorded as Idaho Power's Idaho ROE did not exceed 10.0 percent.  
At December 31, 2016, the full $45 million of additional ADITC remains available for future use under the terms of the 
October 2014 Idaho regulatory settlement stipulation. 

Idaho Power's income tax expense was lower in 2016 compared with 2015 due primarily to greater net flow-through income tax 
benefits, additional share-based compensation tax benefits related to the adoption of Accounting Standards Update 2016-09, 
and lower pretax income.  These decreases were partially offset by a smaller flow-through benefit of a tax deductible make-
whole premium that Idaho Power paid in connection with the early redemption of long-term debt in 2016 compared with the 
flow-through benefit of an early bond redemption in 2015. 

IDACORP's 2016 net income also included a $3.7 million increase, net of tax, in IESCo's earnings, a result of a December 2016 
settlement relating to the California energy market proceedings. Refer to Note 10 - “Contingencies” to the consolidated 
financial statements included in this report for additional information on the settlement.  IDACORP also benefited from 
distributions related to fully-amortized affordable housing investments at IFS, which reduced IDACORP's income tax expense.

Sales Volume and Generation:  In 2016, general business sales volumes decreased less than 1 percent compared with the prior 
year.  Winter temperatures in 2016 were slightly colder than 2015, but milder summer temperatures in 2016 led to lower sales 
volumes. Also, a shorter irrigation season due to a later start in 2016 compared with 2015 resulted in lower usage per irrigation 
customer than during 2015. 

Off-system sales volumes decreased 68 thousand MWh, or 5 percent, during 2016 compared with 2015.  Low wholesale market 
prices reduced economic benefits of operating Idaho Power's non-hydroelectric generation facilities for off-system sales.

Favorable hydroelectric generating conditions from greater snowpack in the spring of 2016 compared with the spring of 2015 
led to increased hydroelectric generation in 2016. Coal-fired generation decreased in 2016 compared with 2015 as low 
wholesale market prices led to an increase in purchased power.

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.

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 typically the primary causes of 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 weather, economic 
conditions, and energy efficiency.  Extreme temperatures increase sales to customers who use electricity for cooling and 
heating, while moderate temperatures decrease sales.  Precipitation levels and the timing of precipitation during the agricultural 
growing season also affect sales to customers who use electricity to operate irrigation pumps.  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.

(2) Normal heating degree-days and cooling degree-days elements are, by convention, the arithmetic mean of the elements computed over 30 consecutive years. 
The annual normal amounts are the sum of the 12 monthly normal amounts. These normal amounts are computed by the National Oceanic and Atmospheric 
Administration.

Idaho Power's rate structure provides for higher rates during the summer when system loads are at their highest, and includes 
tiers such that rates increase as a customer's consumption level increases.  These seasonal and tiered rate structures contribute to 
seasonal fluctuations in revenues and earnings.

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 included the following:

•  Rates:  Rate changes decreased general business revenue by $3.9 million for 2016 compared with 2015, primarily due 
to a decrease in the recovery of power cost adjustment amounts in 2016.  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. 
Also, a shorter irrigation season due to a later start in 2016 compared with 2015 resulted in lower usage per irrigation 
customer in 2016 than during 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 as 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. 

General Business Revenues - 2015 Compared with 2014:  General business revenue increased $28.8 million in 2015 compared 
with 2014.  The factors affecting general business revenues included the following:

•  Rates:  Two rate changes impacted general business revenue—an Idaho PCA rate increase effective June 1, 2014, and 

Idaho PCA rate decrease effective June 1, 2015, both described in Note 3 - "Regulatory Matters" to the consolidated 
financial statements included in this report.  Overall, rate changes combined to decrease general business revenue by 
$2.2 million in 2015. 

•  Customers:  Customer growth of 1.8 percent increased general business revenue by $14.1 million. 

•  Usage:  Lower usage per customer in 2015, primarily driven by the impact of more moderate winter weather on 
residential customer usage, as well as energy efficiency, decreased general business revenue by $0.7 million.  
Residential usage per customer was 1.4 percent lower in 2015.

• 

• 

Sharing:  Revenue sharing of $3.2 million and $8.0 million were recorded in 2015 and 2014, respectively. This sharing 
resulted in a net increase to general business revenue of $4.8 million in 2015 compared with 2014.

Idaho FCA Revenue:  FCA mechanism revenues increased $12.7 million compared with 2014, including the impacts 
of weather and of modifications made to the mechanism by the IPUC effective January 1, 2015.  Idaho Power accrued 
$28.9 million of Idaho FCA revenues in 2015, compared with $16.2 million in 2014.  The modifications to the FCA 
mechanism are described in more detail in "Regulatory Matters" in this MD&A and in Note 3 - "Regulatory Matters" 
to the consolidated financial statements included in this report.

Off-System Sales - 2016 Compared with 2015:  Off-system sales revenue decreased by $5.7 million, or 18 percent.  Off-system 
sales volumes decreased 5 percent in 2016 compared with the same periods in 2015 as low 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 for 2016 was 14 percent lower compared with 2015. 

Off-System Sales - 2015 Compared with 2014:  Off-system sales revenue decreased by $46.3 million, or 60 percent, in 2015.  
Off-system sales volumes decreased 44 percent, as 2014 sales benefited from more favorable market conditions, at times, for 
selling power off-system.  The average price of off-system sales transactions in 2015 was 29 percent lower than 2014, 
indicative of generally lower market prices in 2015.  Decreases in output from hydroelectric resources and an increase in 
overall load due to customer growth also reduced the amount of surplus power available for sale off-system during 2015.

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 revenue and corresponding expense 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 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.

Other Revenues - 2015 Compared with 2014:  Other revenues increased $6.4 million, or 8 percent, in 2015.  The increases in 
2015 were primarily the result of increased electricity transmission (wheeling) volumes and greater customer participation in 
energy efficiency programs.

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 - 2016 Compared with 2015:  Purchased power expense increased $19.3 million, or 9 percent, in 2016.  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.

Purchased Power - 2015 Compared with 2014:  Purchased power expense decreased $18.2 million, or 7 percent, in 2015.  The 
decrease was due primarily to reduced volumes purchased from both PURPA and non-PURPA sources.  Volume decreases were 
partially offset by increases in average prices of both PURPA and non-PURPA sources.

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 - 2016 Compared with 2015:  In 2016, fuel expense decreased $6.7 million, or 4 percent, compared with 2015, 
due principally to decreased output from coal-fired plants and natural gas plants during 2016.  Overall generation decreased 15 
percent 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 Langley and Bridger, 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. 

Fuel Expense - 2015 Compared with 2014:  In 2015, fuel expense decreased $15.0 million, or 7 percent, compared with 2014, 
due principally to decreased output from coal-fired plants during 2015 combined with lower regional natural gas prices for fuel 
used at the natural gas plants.  Overall generation decreased 4 percent due to lower system loads and lower wholesale energy 
prices.  The expense per MWh for natural gas decreased approximately 30 percent in 2015 compared with 2014.  These lower 
natural gas prices led to a shift of generation from coal-fired plants to natural gas plants. 

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, 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 higher than the amount forecasted in power cost 
adjustment rates, which was the case for all periods presented, 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 PCA year that were deferred or 
accrued in the prior PCA year (the true-up component of the PCA). 

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 with less surplus sales than forecasted. The $38.5 million of amortization 
offsets the collection from customers of prior years' deferrals and was lower in 2016 as Idaho Power is amortizing a smaller 
deferral balance in the current year than the prior year.

Power Cost Adjustment Mechanisms - 2015 Compared with 2014:  Actual net power supply cost deferrals decreased in 2015 
relative to 2014, a change of $12.3 million—from $48.1 million to $35.8 million.  Power supply costs collected through base 
rates increased on June 1, 2015, resulting in less costs needing to be recovered through the power cost adjustment mechanisms 
since that time.  The $52.6 million million of amortization offsets the collection from customers of prior years' deferrals.  

Other Operations and Maintenance Expenses:  The changes in other O&M expenses for the periods presented are discussed 
below.

O&M - 2016 Compared with 2015:  Other O&M expense increased by $9.7 million in 2016 compared with 2015, an increase of 
3 percent, due primarily to the following factors:

labor-related expenses increased $6.5 million, or 3 percent, in 2016 due to normal escalations in labor and benefits 
costs and higher variable employee costs; 
scheduled maintenance at the Langley Gulch natural gas-fired generation plant increased O&M expenses $1.6 million; 
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.

O&M - 2015 Compared with 2014:  Other O&M expense decreased by $12.4 million in 2015 compared with 2014, a decrease 
of 3.5 percent, due to the following factors:

• 

• 

• 

$16.7 million was recorded as additional pension expense in 2014 related to a December 2011 Idaho regulatory 
settlement agreement, which required sharing with Idaho customers of a portion of earnings in excess of a 10.0 percent 
Idaho ROE (thereby reducing customers' future pension obligations).  There were no additional expenses related to the 
settlement agreement in 2015; 
excluding the additional 2014 pension expense, labor-related expenses increased $2.1 million, or 1.1 percent, in 2015 
due to normal escalations in labor and benefits costs; and
hydroelectric generation expenses increased $2.0 million, primarily due to increased repair costs and purchased 
services.

Income Taxes

IDACORP's and Idaho Power's 2016 income tax expense decreased $9.3 million and $11.0 million, respectively, when 
compared to 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.

44

 
 
 
 
 
 
 
 
 
 
Income tax expense in 2015 increased significantly compared with 2014, principally as a result of a 2014 flow-through tax 
benefit related to the cumulative impact of tax accounting method changes for Idaho Power’s capitalized repairs deduction that 
did not recur in 2015.  For additional information relating to IDACORP's and Idaho Power's income taxes, including 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 $287 million in 2016, $284 million in 2015, and $265 million in 2014.  
Idaho Power expects these substantial capital expenditures to continue, with estimated total capital expenditures of 
approximately $1.5 billion expected over the period from 2017 through 2021.  

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 17, 2017, 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 2017, the companies believe they will be 
able to meet capital requirements and fund corporate expenses during 2017 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 
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.  The companies do not expect to redeem any existing outstanding debt during 2017.

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, 2016, 
IDACORP's and Idaho Power's capital structures, as calculated for purposes of applicable debt covenants, were as follows: 

45

 
 
 
 
 
 
 
 
 
IDACORP

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 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:

• 

• 

• 

• 

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.

IDACORP's and Idaho Power's operating cash inflows in 2015 were $353 million and $346 million, respectively, a decrease of  
$11 million for IDACORP and a slight increase for Idaho Power when compared with 2014.  Significant items that affected the 
companies' operating cash flows in 2015 relative to 2014 were as follows:

• 

• 

• 

• 

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 $18 million;
Idaho Power made $39 million of cash contributions to its defined benefit pension plan in 2015, compared with $30 
million of cash contributions during 2014; 
changes in deferred taxes and in taxes accrued and receivable combined to increase cash flows by $34 million and $50 
million at IDACORP and Idaho Power, respectively; and  
comparative changes in working capital balances due primarily to timing—principally related to a smaller decrease in 
accounts receivable in 2015 compared to the decrease in accounts receivable in 2014.  Changes in accounts receivable 
balances reduced operating cash flows $16 million and $18 million for IDACORP and Idaho Power, respectively.

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 $297 million, $294 million, and $274 million in 2016, 2015, and 2014, 
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 $8 million and $11 million in 2016 and 2015 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 $15 million, $14 million, and $8 million of available-for-sale securities in 2016, 2015, and 
2014, respectively. In 2016 and 2015, Idaho Power received $16 million and $34 million, respectively, of proceeds from the 
sales of available-for-sale securities and used $10 million and $30 million of the proceeds, respectively, to acquire company-
owned life insurance. 

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 2016, 2015, and 2014:

• 

• 

• 

• 

• 

• 

• 

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 $105 million, $97 million, and $88 million in 2016, 
2015, and 2014, respectively;
IDACORP's net change in commercial paper borrowings provided cash of $2 million in 2016 and used cash of $11 
million and $23 million in 2015 and 2014, respectively; and
Idaho Power borrowed $22 million in commercial paper in December 2016.

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 company does not anticipate issuing any shares of its common stock outside of its equity or deferral compensation programs 
in 2017.

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 

47

 
 
 
 
 
 
 
 
 
 
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, 2016, 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, 2016, Idaho Power could issue approximately $1.7 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 
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, 2016, the leverage ratios for 
IDACORP and Idaho Power were 45 percent and 47 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, 2016, 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 
2017.

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 

48

 
 
 
 
 
 
 
 
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 with the consent of all the lenders, extending the 
maturity date under both credit agreements to November 5, 2021.  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 
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, 2016, Idaho Power had posted no 
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, 2016, the amount of 
additional collateral that could be requested upon a downgrade to below investment grade is approximately $11.6 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 $287 million during the year ended December 31, 2016.  
The table below presents Idaho Power's estimated cash requirements for construction, excluding AFUDC, for 2017 through 
2021 (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 2017 through 2021 and estimated costs include the following:

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.  Idaho Power has 
expended $100 million, excluding AFUDC, on SCR installation at units 3 and 4 through December 31, 2016.  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 uncertainty 
resulting from pending environmental regulation and 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.  The Boardman-to-Hemingway line was included in the preferred resource portfolio in 
Idaho Power’s 2015 IRP.  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.  
Assuming both other participants fund their full share of the total cost of the permitting phase of the project, Idaho Power's 
estimated share of the cost of the permitting phase of the project is approximately $44 million, including Idaho Power's 
AFUDC.  Total cost estimates for the project are between $1.0 billion and $1.2 billion, including AFUDC.  This cost estimate 
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 $45 million of Idaho Power's share of costs related to early construction efforts 
primarily included in the periods 2019-2021.  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 $87 million has been expended on the Boardman-to-Hemingway project through December 31, 2016.  Pursuant 
to the terms of the joint funding arrangements, Idaho Power has received approximately $42 million of that amount as 
reimbursement from the project participants as of December 31, 2016.  Idaho Power has accrued in receivables approximately 
$16 million more that will be billed by Idaho Power in the future to the project participants for expenses Idaho Power has 
incurred, for a total amount reimbursable by joint permitting participants of $58 million.  In addition to the $58 million amount, 
$6 million is subject to reimbursement at a later date from the joint permitting participants, assuming their continued 
participation in the project, for expenses Idaho Power incurred prior to execution of the joint funding arrangements.  Joint 
permitting participants are obligated to reimburse Idaho Power for their share of any future project permitting expenditures 
incurred by Idaho Power.  Idaho Power plans to seek recovery of its share of project costs through the regulatory process.

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, the Army Corps of Engineers, and certain 
other federal agencies.  The BLM, as the lead federal agency on the National Environmental Policy Act review, issued a final 
environmental impact statement (EIS) for the project on November 25, 2016. As of the date of this report, the BLM's schedule 
provides for the issuance of a record of decision in 2017.  In the separate Oregon state permitting process, Idaho Power expects 
its amended preliminary application for site certificate to be deemed complete by the Oregon Department of Energy in 2017.  
Idaho Power is unable to determine an in-service date for the line but, given the status of ongoing permitting activities, expects 
the in-service date would be in 2023 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 $32 million on the permitting phase of the project through December 31, 2016.  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 in addition to approximately $35 million of Idaho 
Power's share of costs related to early construction efforts primarily in the periods 2019-2021.  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.

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.  On January 20, 2017, the BLM released its 
record of decision for the remaining two transmission line segments. In September 2016, the U.S. Department of Interior Board 
of Land Appeals affirmed the BLM's November 2013 record of decision, which was challenged by certain third-parties. In 
February 2017, the State of Idaho and others filed with the U.S. Department of Interior Board of Land Appeals notices of 
appeal and requests for a stay of the BLM’s record of decision.

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 2021.  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.  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.  Idaho Power filed 
its most recent IRP in June 2015 and expects to file its 2017 IRP in June 2017.  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 2015 IRP included as near-term action items the continued permitting and planning for 
the Boardman-to-Hemingway transmission line and further investigation of the early retirement of the North Valmy power plant 
in collaboration with the plant's co-owner.  Idaho Power filed applications with the IPUC and OPUC in October and November 
2016, respectively, requesting accelerated depreciation of the North Valmy plant in connection with the potential early closure 
of the plant, which remain pending.  The near-term action plan also included commencement of an economic evaluation of 
environmental control retrofits for units 1 and 2 at the Jim Bridger power plant.  Additional information on Idaho Power's 2015 
IRP and 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, $39 million, and $30 million to its defined benefit pension plan in 2016, 2015, and 2014, 
respectively.  Idaho Power estimates that it has no minimum contribution requirement for 2017, though it plans to contribute 
between $20 million and $40 million to the pension plan during 2017.  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.  In 2017 and beyond, Idaho Power expects continuing significant contribution obligations 
under the pension plan.  Refer to Note 11 - "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, 2016, Idaho Power's deferral balance associated with the Idaho jurisdiction was $105 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.

(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, 2016.
(3) The operating leases include right-of-way easements.  Approximately $13 million of the obligations included have 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.
(4) Approximately $6 million of the amounts in cogeneration and small power production and $23 million of the amounts in other purchase obligations 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.  Other purchase obligations also includes 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.  
(5) Idaho Power estimates pension contributions based on actuarial data.  As of the date of this report, Idaho Power cannot estimate pension contributions 
beyond 2021 with any level of precision, and amounts through 2021 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 2014, 2015, and 2016, IDACORP's board of directors voted to 
increase the quarterly dividend to $0.47 per share, $0.51 per share, and $0.55 per share of IDACORP common stock, 
respectively.  IDACORP's dividends during 2016 were 53 percent of actual 2016 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.

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 $71 million at December 31, 2016, representing IERCo's one-third share of BCC's total 
reclamation obligation of $212 million.  BCC has a reclamation trust fund set aside specifically for the purpose of paying these 
reclamation costs.  At December 31, 2016, the value of the reclamation trust fund totaled $78 million.  During 2016, the 
reclamation trust fund distributed approximately $6 million 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.  During 2017, Idaho Power 
plans to continue to assess its need to file, and timing of, a general rate case in its two retail jurisdictions, based on its 
consideration of the factors described above. 

Notable Retail Rate Changes in Idaho and Oregon

Included in the table that follows are notable regulatory developments during 2014, 2015, and 2016 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.
(2) The rate changes for the Idaho PCA and FCA are applicable only for one-year periods.  Similarly, a portion of the rate changes from the Oregon APCU are 
applicable only for one-year periods.
(3) 2014 PCA rates reflect (a) the application of $20.0 million of surplus Idaho energy efficiency rider funds, (b) $8.0 million of customer revenue sharing for 
the year 2013 under a regulatory settlement agreement approved in December 2011, and (c) a $99.0 million shift in base net power supply expenses from 
recovery via the PCA mechanism to recovery through base rates. 
(4) See footnote (3) above.  Approval of the transfer of collection of specified power supply costs from the Idaho PCA mechanism to Idaho base rates resulted 
in no net change in customer rates.
(5) 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.
(6) 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.

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 

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.

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.  The more specific terms and conditions of the December 2011 Idaho settlement 
stipulation are described in Note 3 - "Regulatory Matters - Notable Idaho Regulatory Matters" to the consolidated financial 
statements included in this report.  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 2016, 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, 2016, the full $45 million of 
additional ADITC remains available for future use under the terms of the settlement stipulation.

Idaho Power recorded the following for sharing with customers under the December 2011 and October 2014 Idaho Settlement 
Stipulations (in millions):

Modifications to Idaho Annual Rate Adjustment 

PCA Mechanism: In July 2014, the IPUC opened a docket pursuant to which Idaho Power, the IPUC Staff, and other interested 
parties evaluated Idaho Power's application of the true-up component of the PCA mechanism.  The July 2014 docket arose from 
a prior order of the IPUC, which noted that the IPUC Staff believed that Idaho Power's application of the true-up component 
introduced a line-loss bias that inflated the true-up revenue that Idaho Power collects under the PCA.  In May 2015, the IPUC 
approved a settlement stipulation that modified the calculation of the true-up component of the PCA mechanism.  The 
mechanics of the PCA mechanism and the terms of the PCA settlement stipulation are described in Note 3 - "Regulatory 
Matters" to the consolidated financial statements included in this report. 

FCA Mechanism:Also 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.  Concerns cited included the 
application of weather-normalization, the customer count methodology, the rate adjustment cap, cross-subsidization issues, and 
whether the FCA is in fact effectively removing Idaho Power's disincentive to aggressively pursue energy efficiency 

The FCA 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.  Stated generally, under the FCA Idaho Power charges residential and small commercial customers when it recovers 
less "actual fixed costs per customer" than the base level of fixed costs that the IPUC authorized for recovery through rates in 
the last general rate case, and Idaho Power credits those customers when its "actual fixed costs per customer" recovered exceed 
that base level of fixed costs. The FCA 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

57

 
 
 
 
 
 
 
 
 
 
In May 2015, the IPUC approved a settlement stipulation that modified the FCA mechanism by replacing weather-normalized 
sales with actual sales in the calculation of the FCA, applicable for the entirety of calendar year 2015 and thereafter, with new 
rates effective June 1, 2016.  The settlement stipulation also provided that a modified rate design should be considered at a later 
time for residential and small commercial customers to address the financial disincentive caused by the existing rate design that 
the FCA is intended to remove.  The rate design may include, but would not be limited to, reduced energy charges, increased 
monthly service charges, and the introduction of demand char

In years when actual sales per customer are higher than weather-normalized sales due to high summer or low winter 
temperatures, Idaho Power expects that the new FCA methodology will be less favorable to Idaho Power than the prior 
methodology.  Conversely, Idaho Power expects that the new FCA methodology will be more favorable to Idaho Power in years 
when actual sales per customer are lower than weather normalized sales due to cooler summer or warmer winter temperatures. 

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.   

As noted above under the heading "Idaho and Oregon General Rate Cases and Base Rate Adjustments," in light of the existence 
of permanent increases in power supply costs, in March 2014 the IPUC issued an order approving Idaho Power's application 
requesting recovery of a portion of its ongoing power supply costs through base rates rather than through the PCA mechanism.  

The following table summarizes the change in deferred net power supply costs over the prior two years.

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 requests 
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 the spring 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.  Refer to Note 3 - "Regulatory Matters" to the consolidated 
financial statements included in this report for additional information relating to Idaho Power's anticipated participation in the 
Western EIM.

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 2016, Idaho 
Power filed its 2016 final transmission rate with the FERC, reflecting a transmission rate of $25.52 per kW-year, to be effective 
for the period from October 1, 2016, to September 30, 2017.  Idaho Power's final rate was based on a net annual transmission 
revenue requirement of $127.4 million.  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 
a FERC order, the current formula rate methodology will phase in the increase over a two-year period from October 1, 2016 
through September 30, 2018.  

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. 

Depreciation Rate Requests

In October and November 2016, Idaho Power filed applications with the IPUC and OPUC, respectively, requesting 
authorization to (a) accelerate depreciation for the North Valmy coal-fired power plant, to allow the plant to be fully depreciated 
by December 31, 2025, (b) establish a balancing account to track the incremental costs and benefits associated with the 
accelerated depreciation date, and (c) adjust customer rates to recover the associated incremental annual levelized revenue 
requirement in an aggregate amount of $29.6 million.  Idaho Power also filed applications with the IPUC and OPUC requesting 
approval to institute revised depreciation rates for Idaho Power's other electric plant-in-service and adjust base rates by an 
aggregate of $7.4 million to reflect the revised depreciation rates applied to electric plant-in-service balances subject to the most 
recent general rate case. The depreciation filings are described in Note 3 - "Regulatory Matters" to the consolidated financial 
statements included in this report.  

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 will submit relicensing costs and costs related to new licenses to regulators for recovery 

59

 
 
 
 
 
 
 
 
 
through the ratemaking process and, in December 2016, submitted a request for a determination of prudency, which is described 
below.  As of December 31, 2016, relicensing costs of $249 million for the HCC, Idaho Power's largest hydroelectric complex 
and a major relicensing effort, were included in construction work in progress.  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, 2016, Idaho Power's regulatory liability for collection of AFUDC relating to the HCC was $103 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 species pending the relicensing of the project.  In August 2007, the FERC Staff issued a final 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, specifically forbids Idaho Power from 
reintroducing certain fish protected under the ESA, into Idaho's waters. 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.  As of the 
date of this report, Idaho Power is considering other actions it may take to obtain a resolution of the issue. 

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 the process for construction of new aerated runners at the Brownlee project 
(part of the HCC) at an estimated cost of $50 million.  The first of four units was installed in 2016 and Idaho Power plans to 
install one unit in each year from 2017 through 2019.  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 

60

 
 
 
 
 
 
 
 
 
  
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 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 
occur no earlier than 2021.  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 future inclusion in retail rates.

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% with 
customers in the Idaho jurisdiction) of those proceeds through the PCA.  For the years ended December 31, 2016, 2015, and 
2014, Idaho Power's REC sales totaled $1.0 million, $1.8 million, and $3.2 million, respectively.  The comparative decrease in 
REC sales resulted primarily from the elimination of a REC purchase and sale agreement with a third party. 

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 December 2012, described below, 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 power from both CSPP projects under 
PURPA 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 December 31, 2016, 
Idaho Power had contracts to purchase energy from 117 on-line CSPP projects, twelve additional projects expected to come on-
line in 2017, and three projects expected to come on-line in 2019.  The following table sets forth, as of December 31, 2016, the 
resource type and nameplate capacity of Idaho Power's signed CSPP and non-CSPP related agreements.  These agreements have 
original contract terms ranging from one to 35 years.

All but three of the projects not yet on-line are expected to be on-line no later than mid-year 2017 (three solar projects are 
scheduled to be on-line in 2019).

In April 2015, Idaho Power made filings with the OPUC requesting, among other things, a reduction in the term of standard 
PURPA power purchase agreements from 20 years to two years for projects above 100 kW, in a manner consistent with its 
Idaho jurisdiction where the IPUC reduced the length of PURPA contracts that involve avoided-cost-based pricing to two years, 
and a temporary suspension of Idaho Power's obligation to enter into new fixed-price standard PURPA agreements during the 
pendency of the proceedings.  In March 2016, the OPUC issued an order permanently reducing the eligibility cap for solar 
project standard contracts to 3 MW, with all other resource types retaining an eligibility cap of 10 MW.  In its order, the OPUC 
retained the requirement for up to 20-year contract lengths for Oregon jurisdictional projects, comprised of 15 years of fixed 
prices and five years of market index prices.

In June 2016, the FERC held a technical conference on implementation issues under PURPA, including the mandatory power 
purchase obligation and the methods for determining avoided costs for those purchases.  The conference also involved a 
discussion of PURPA project siting issues and minimum contract term lengths.  In September 2016, the FERC filed a notice 
inviting post-technical conference comments on (1) the use of the "one-mile rule" to determine the size of an entity seeking 
certification as a small power production qualifying facility and (2) minimum standards for PURPA-purchase contracts.  In 
November 2016, Idaho Power provided comments to the FERC specifically addressing Idaho Power’s position regarding the 
two items of which the FERC invited comments. Idaho Power is unable to predict what policy or rulemaking actions or 
proceedings, if any, on PURPA-related issues will result from the technical conference.

ENVIRONMENTAL MATTERS

Overview

Idaho Power is 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.

62

 
 
 
 
 
 
 
 
 
  
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.  Idaho Power filed an application with the IPUC and OPUC in October 
and November 2016, respectively, requesting accelerated depreciation of the North Valmy plant in connection with the potential 
early closure of the plant. Additionally, in light of the uncertainty resulting from pending environmental regulation and the 
substantial estimated cost of SCR controls, Idaho Power is assessing whether to move forward with the installation of SCR on 
units 1 and 2 at the Jim Bridger coal-fired power plant.

In addition to 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 2017 to 2019.  Given the uncertainty of future environmental regulations and 
technological advances, Idaho Power is unable to predict its environmental-related expenditures beyond 2019, though they 
could be substantial.  Furthermore, the recent presidential and congressional elections in the United States 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.

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, 
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. 

63

 
 
 
 
 
 
 
 
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. 

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.  As of the date of this report, Idaho Power is participating in 
the proceedings in an effort to protect its interests.

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 2017 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, 
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;

64

 
 
 
 
 
 
 
 
• 

• 
• 

• 

extreme weather events 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 adversely 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; Final Rule Under CAA Section 111(d):  The EPA has become increasingly 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.  The final rule “tailors” the requirements of these CAA permitting programs 
to limit which facilities will be required to obtain Prevention of Significant Deterioration (PSD) and Title V permits.  The rules 
require the use of "best available control technology" for GHG emissions if a new major source or modification of an existing 
major source is projected to result in GHG emissions of at least 75,000 tons per year (CO2 equivalent).  In addition, Title V 
permit renewals or modifications for existing major sources must include applicable requirements relating to GHGs.  While the 
rules are 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, 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.

On February 9, 2016, the U.S. Supreme Court issued an order staying the implementation of the rule pending the completion of 
certain legal challenges, which has an uncertain impact on the ultimate timeline for implementation of the rule.  Idaho Power's 
owned and co-owned generation facilities are in the states of Idaho, Nevada, Oregon, and Wyoming. Despite the current stay on 
implementation, Idaho Power is working with state representatives, neighboring utilities, and others as it analyzes the rule and 
prepares for compliance.  Because the rule is premised on state implementation plans, the terms of which Idaho Power does not 
control, and due to the potential changes in legislation, regulation, and government policy with respect to environmental matters 
as a result of the 2016 U.S. presidential and congressional elections, as of the date of this report Idaho Power is unable to 
determine the financial or operational impacts of the final rule. 

65

 
 
 
 
 
 
 
 
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 
may require certain large 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, but in May 2007, Idaho’s governor issued Executive 
Order 2007-05, which directed the Idaho Department of Environmental Quality to work with the state government to 
implement GHG reductions within each agency, complete a statewide emissions inventory, and provide recommendations to the 
governor, among other tasks.  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. 

66

 
 
 
 
 
 
 
 
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.  In November 2010, PacifiCorp and the WDEQ signed a settlement agreement under 

67

 
 
 
 
 
 
 
 
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. Idaho Power believes 
that the final rule potentially expands 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.  As a result of the potential expansion, the final rule may result in additional permitting and regulatory 
requirements under multiple provisions of the CWA.  Idaho Power has analyzed the final rule and expects that while it may 
incur additional permitting 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 and the existing application of the CWA to most of Idaho Power's facilities, including its hydroelectric 
plants. 

In October 2015, the United States Court of Appeals for the Sixth Circuit issued a nationwide stay of the final waters of the 
United States rule from becoming effective.  In response to the Sixth Circuit's decision, the EPA resumed nationwide use of the 
agency's prior regulations defining the term “waters of the United States.”  The EPA stated that those regulations will be 
implemented as they were prior to August 27, 2015, by applying relevant case law, applicable policy, and the best science and 
technical data on a case-by-case basis in determining which waters are protected by the CWA.

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 U.S. Department of the Interior announced that it would launch a comprehensive review to identify and 
evaluate potential reforms to the federal coal lease program.  The review is intended to address questions such as how, when, 
and where to lease coal resources, how to account for the environmental and public health impacts of federal coal production, 
and how to ensure taxpayers are earning a fair return for the use of the coal resources.  The U.S. Department of the Interior 
stated that it will not issue new coal leases during the pendency of the review, except under limited circumstances, but mining 
under existing leases will not be suspended during the review.  BCC, which mines and supplies coal to the Jim Bridger coal-
fired power plant, currently leases its coal under federal, state, and private coal leases.  It is uncertain how new federal lease 
applications will be handled during the U.S. Department of the Interior's coal lease review.  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, depending on the outcome of the Department of the Interior's review, the 
availability of coal resources could decline and the cost of leases for coal resources could increase, which could increase 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.

68

 
 
 
 
 
 
 
 
 
 
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 territory 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 $1.5 billion of regulatory assets and $447 million of regulatory liabilities at December 31, 2016.  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.  Either circumstance could have a material effect on Idaho Power’s 
financial condition or results of operations.

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 
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, 2016, with maturities matching the projected cash outflows of 
the plans.  Based on the results of this analysis, the discount rate used to calculate the 2017 pension expense will be decreased 
to 4.45 percent from the 4.60 percent used in 2016.

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 

69

 
 
 
 
 
 
 
 
 
 
 
 
 
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 2017 pension expense will be 7.5 
percent, the same assumption as was used for 2016.

Gross net periodic pension and other postretirement benefit cost for these plans totaled $52 million, $51 million, and $32 
million for the years ended December 31, 2016, 2015, and 2014, respectively, including amounts deferred as regulatory assets 
(see discussion below) and amounts allocated to capitalized labor.  For 2017, gross pension and other postretirement benefit 
costs are expected to total approximately $51 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

Additionally, a 0.5 percent increase in the plans' discount rates would have resulted in a $74 million decrease in the combined 
benefit obligations of the plans as of December 31, 2016.  A 0.5 percent decrease in the plans' discount rates would have 
resulted in an $83 million increase in the combined benefit obligations of the plans as of December 31, 2016.

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, 2016, a total of $105 million of expense was 
deferred as a regulatory asset.  Approximately $23 million is expected to be deferred in 2017.  Idaho Power recorded pension 
expense in 2016, 2015, and 2014 of $19 million, $19 million, and $35 million, respectively.

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.

Contingent Liabilities

An estimated loss from a loss contingency is charged to income if (a) it is probable that a liability had been incurred at the date 
of the financial statements and (b) the amount of the loss can be reasonably estimated.  If a probable loss cannot be reasonably 
estimated, no accrual is recorded but disclosure of the contingency, if material, in the notes to the financial statements is 
required.  Gain contingencies are not recorded until realized.  IDACORP and Idaho Power have a number of unresolved issues 
related to regulatory and legal matters.  If the recognition criteria have been met, liabilities have been recorded.  Estimates of 
this nature are highly subjective and the final outcome of these matters could vary significantly from the amounts that have 
been included in the financial statements.

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, 2016.  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, 2016, IDACORP and Idaho Power had $1.1 million and $16.1 million in floating rate 
debt, net of short-term investments.  The fair market value of this debt approximates the net carrying amount as the cost of 
borrowing is variable and approximates current market rates.  Assuming no change in financial structure, if variable interest 
rates were to average one percentage point higher than the average rate on December 31, 2016, annual interest expense would 
increase and pre-tax earnings would decrease by an insignificant amount for both IDACORP and Idaho Power.

Fixed Rate Debt:  As of December 31, 2016, both IDACORP and Idaho Power had $1.7 billion in fixed rate debt, with a fair 
market value of approximately $1.8 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 $256 million if market interest rates were to decline by one percentage point from their December 31, 2016, 
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.

71

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 
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, 2016, Idaho Power had no 
performance assurance collateral posted.  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, 2016, the 
amount of collateral that could be requested upon a downgrade to below investment grade was approximately $11.6 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 wholly-owned subsidiaries include IDACORP Financial Services, Inc. (IFS), an investor in affordable 
housing and other real estate investments; 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); and IDACORP Energy 
Services Co. (IESCo), which is the former limited partner of, and current successor by merger to, IDACORP Energy L.P., a 
marketer of energy commodities that wound down operations in 2003.

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, 2016, Marysville 
had approximately $18 million of assets, primarily a hydroelectric plant, and approximately $11 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 $82 million at December 31, 2016, and Idaho Power's maximum exposure to loss is the carrying value, any additional 
future contributions to BCC, and a $71 million guarantee for mine reclamation costs, which is discussed further in Note 9.

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 $8 million at December 31, 2016.

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).  

86

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 

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). 

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.

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, litigation, 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, 2016 and 2015.  Once a receivable is 
determined to be impaired, any further interest income recognized is fully reserved.

87

 
 
 
 
 
 
 
 
 
 
 
 
 
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. In addition, regulatory mechanisms in place in Idaho and Oregon affect the reported amount of revenue.  See Note 3 
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;
franchise fees and similar taxes related to energy consumption.  None of these collections are reported on the income 
statement; 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 2.64 percent in 2016 and 2.68 
percent in both 2015 and 2014.

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 2016, 2015, or 2014.

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 

88

 
 
 
 
 
 
 
 
 
 
 
 
 
interest expense.  Idaho Power’s weighted-average monthly AFUDC rate was 7.6 percent for 2016 and 2015 and 7.7 percent for 
2014.

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.

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 immaterial amounts in prior periods' consolidated financial statements and 
footnotes have been reclassified to conform with the current period presentation.

New and Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, 
Compensation--Stock Compensation (Topic 718) - Improvements to Employer Share-Based Payment Accounting, simplifying 
several aspects of the accounting for stock compensation paid to employees.  As allowed, IDACORP and Idaho Power elected 
to early adopt the provisions of the new standard in the first quarter of 2016 under the modified retrospective method, with the 
cumulative effect of adoption recorded as an adjustment to 2016 beginning retained earnings.  The principal changes under the 
new accounting standard include the following: 

•  Excess or deficit income tax benefits on share-based transactions are recorded as income tax expense rather than in 

• 

• 

additional-paid-in-capital.
Previously recorded forfeiture estimates of approximately $0.2 million are reported as a decrease to beginning retained 
earnings.  IDACORP made an accounting policy election to account for share-based award forfeitures as they occur, 
rather than making an estimate of future forfeitures.
In the statement of cash flows, excess tax benefits on share-based payments are presented in operating activities in the 
same manner as other cash flows related to income taxes.  Previously, these cash flows were presented in financing 
activities.  Prior periods were not restated for this change.

In May 2015, the FASB issued ASU 2015-07, Fair Value Measurement (Topic 820) - Disclosures for Investments in Certain 
Entities That Calculate Net Asset Value per Share (or Its Equivalent), which removes the requirement to categorize within the 
fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient.  As 
required, IDACORP and Idaho Power have adopted the provisions of this ASU at December 31, 2016, and accordingly, have 
retrospectively adjusted prior periods. 

In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810) - Amendments to the Consolidation Analysis, 
which revises the consolidation model that reporting entities use when determining what entities are to be consolidated.  The 
amendments focus on limited partnerships and similar legal entities.  The adoption of ASU 2015-02 in the first quarter of 2016 
did not have a material impact on IDACORP's or Idaho Power's financial statements.

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 continue to assess the impacts of ASU 
2014-09 on their financial statements, including disclosure requirements, but the companies do not expect the new guidance to 
significantly affect revenue recognition for tariff-based sales, which represent a significant majority of the companies' general 
business revenue.  Accordingly, the companies do not expect the adoption of ASU 2014-09 to have a material effect on their 
financial statements; however, a number of industry-specific implementation issues are still unresolved and the final resolution 
of these issues could affect the companies' accounting for contributions in aid of construction, sales of renewable energy credits, 
alternative revenue programs, and recognition of revenue when collectability is in question.  The guidance in ASU 2014-09 is 
effective for annual reporting periods beginning after December 15, 2017, including interim periods.  The guidance permits two 
implementation approaches, one requiring retrospective application of the new standard with restatement of prior years (full 
retrospective approach) and one 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 plan to 
adopt ASU 2014-09 on January 1, 2018, using the modified-retrospective approach.

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 annual reporting periods beginning after December 15, 2018, including interim periods, 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.  At this time, the companies do not know, and cannot 
reasonably estimate, the dollar impact of the adoption.  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 areas.

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 
annual reporting periods beginning after December 15, 2017, including interim periods, with early adoption permitted one year 
earlier.  IDACORP and Idaho Power do not plan to early adopt the standard.  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.

(1) In 2014, Idaho Power finalized an income tax accounting method change for the electric generation property portion of its capitalized repairs tax method and 
the final tangible property regulations. The cumulative impact of the method changes resulted in a net flow-through income tax benefit for 2014. The IRS 
approved the method changes as part of IDACORP's Compliance Assurance Process (CAP) examinations.

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.  See Note 1 for further discussion of 
accounting policies related to income taxes.

Tax Credit Carryforwards

As of December 31, 2016, IDACORP had $103.5 million of general business credit carryforwards for federal income tax 
purposes and $39.1 million of Idaho investment tax credit carryforward.  The general business credit carryforward period 
expires from 2025 to 2036, and the Idaho investment tax credit expires from 2021 to 2030.

Uncertain Tax Positions

IDACORP and Idaho Power believe that they have no material income tax uncertainties for 2016 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 2016 for federal and 2012-2016 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 2016, the IRS completed its examination 
of IDACORP's 2015 tax year with no unresolved income tax issues. 

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 the unfunded obligation of Idaho Power’s pension and postretirement benefit plans, which are discussed in Note 11.
(3) The energy efficiency asset represents the Oregon jurisdiction balance and the liability represents the Idaho jurisdiction balance. 
(4)  These items are discussed in more detail in this Note 3. 
(5) Asset retirement obligations and removal costs are discussed in Note 13.
(6) Mark-to-market assets and liabilities are discussed in Note 16.
(7) A portion not earning a return as of December 31, 2016, will be eligible to earn a return as of January 1, 2018.
(8) 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.

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.

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

(millions) Notes
$

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 reduction due to the transfer of
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, and (b) $4.0 million of surplus Idaho energy efficiency
rider funds.

June 1, 2014

$

(88.2) 2014 PCA rates are net of (a) $20.0 million of surplus Idaho energy efficiency rider funds,

and (b) $7.6 million of customer revenue sharing under a regulatory settlement stipulation.  In
addition, on June 1, 2014, there was an increase in base net power supply costs that shifted
$99.3 million in power supply expenses from recovery via the PCA mechanism to recovery
via base rates.  The shifting of base net power supply costs is discussed in more detail below.

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. 

In July 2014, the IPUC opened a docket pursuant to which Idaho Power, the IPUC Staff, and other interested parties further 
evaluated Idaho Power's application of the true-up component of the PCA mechanism and whether a deferral balance 
adjustment was appropriate.  While the IPUC's docket was closed in August 2014 with no adjustment to the PCA true-up 
revenue amount, Idaho Power subsequently met with the IPUC Staff to explore approaches to increasing the accuracy of the 
actual cost recovery under the PCA mechanism.  In May 2015, the IPUC approved a settlement stipulation that resulted in the 
replacement of the existing load-based adjustment used for determining the power cost deferrals under the PCA mechanism 
with a similar sales-based adjustment.  The sales-based adjustment functions in the same manner as the previous load-based 
adjustment but measures deviations between Idaho-specific test year sales and actual Idaho sales rather than deviations between 
test year loads and actual loads.  The approved settlement stipulation implemented the new methodology as of January 1, 2015.

95

 
 
 
 
 
 
 
 
 
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 no greater than 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 no less than 100 basis points 
above Idaho Power’s last authorized Oregon ROE.  Oregon jurisdiction power supply cost changes under the APCU and PCAM 
during each of 2016, 2015, and 2014 are summarized in the table that follows:

Year and

Mechanism APCU or PCAM Adjustment
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.

2015 APCU

A rate decrease of $0.7 million annually took effect June 1, 2015.

2014 PCAM Actual net power supply costs were within the deadband, resulting in no deferral.

2014 APCU

A rate increase of $0.4 million annually took effect June 1, 2014.

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. 

December 2011 Idaho Settlement Stipulation:  In December 2011, the IPUC issued an order, separate from the then-pending 
general rate case proceeding, approving a settlement stipulation that provided as follows: 

• 

• 

• 

If Idaho Power's actual Idaho-jurisdiction return on year-end equity (Idaho ROE) for 2012, 2013, or 2014 was less 
than 9.5 percent, then Idaho Power could amortize up to a total of $45 million of additional accumulated deferred 
investment tax credits (ADITC) to help achieve a minimum 9.5 percent Idaho ROE in the applicable year.

If Idaho Power's actual Idaho ROE for 2012, 2013, or 2014 exceeded 10.0 percent, the amount of Idaho Power's 
Idaho-jurisdiction earnings exceeding a 10.0 percent and up to and including a 10.5 percent Idaho ROE for the 
applicable year would be shared equally between Idaho Power and its Idaho customers in the form of a rate reduction 
to become effective at the time of the subsequent year's PCA mechanism adjustment.

If Idaho Power's actual Idaho ROE for 2012, 2013, or 2014 exceeded 10.5 percent, the amount of Idaho Power's Idaho 
jurisdictional earnings exceeding a 10.5 percent Idaho ROE for the applicable year would be allocated 75 percent to 
Idaho Power's Idaho customers as a reduction to the pension regulatory asset and 25 percent to Idaho Power.

As Idaho Power's Idaho ROE exceeded 10.5 percent in 2014, Idaho Power did not amortize additional ADITC, but instead 
shared $24.7 million of its Idaho-jurisdiction earnings with Idaho customers. Of the amount shared in 2014, $8.0 million was 

96

 
 
 
 
 
 
 
 
 
returned as a rate reduction as part of the 2015 PCA mechanism adjustment and $16.7 million was recorded as a pre-tax charge 
to pension expense. 

October 2014 Idaho Settlement Stipulation:  In October 2014, the IPUC issued an order approving an extension, with 
modifications, of the terms of the 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 ADITC contemplated 
by the settlement stipulation has been amortized.  The provisions of the new settlement stipulation are as follows:

• 

• 

• 

• 

• 

If Idaho Power's annual 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.  

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 2016, Idaho Power recorded no additional ADITC amortization and no provision for 
sharing with customers, as its 2016 Idaho ROE was between 9.5 percent and 10.0 percent. Accordingly, at December 31, 2016, 
the full $45 million of additional ADITC remains available for future use under the terms of the settlement stipulation.

In 2016, 2015, and 2014, Idaho Power recorded the following for sharing with customers under the December 2011 and 
October 2014 Idaho settlement stipulations (in millions):

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.

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 charges effective June 1, 2016.

Depreciation Rate Requests

In 2016, Idaho Power conducted a depreciation study of all electric plant-in-service that provided updates to net salvage 
percentages and service life estimates for all Idaho Power plant assets.  Based on the study, in October and November 2016, 
Idaho Power filed applications with the IPUC and OPUC, respectively, requesting approval to institute revised depreciation 
rates for Idaho Power's electric plant-in-service and adjust base rates by an aggregate of $7.4 million to reflect the revised 
depreciation rates applied to electric plant in service balances subject to the most recent general rate cases. The proposed 
adjustments in these applications are an overall rate increase of 0.6 percent in Idaho and 1.3 percent in Oregon.

At the same time, Idaho Power also filed applications with the IPUC and the OPUC requesting authorization to (a) accelerate 
depreciation for the North Valmy coal-fired power plant, to allow the plant to be fully depreciated by December 31, 2025, (b) 
establish a balancing account to track the incremental costs and benefits associated with the accelerated depreciation date, and 
(c) adjust customer rates to recover the associated incremental annual levelized revenue requirement in the aggregate amount of 
$29.6 million.  The proposed adjustment in these applications are an overall rate increase of 2.5 percent in Idaho and 1.9 
percent in Oregon.

Idaho Power expects the IPUC and the OPUC to enter final orders in both matters prior to June 2017 in Idaho and November 
2017 in Oregon. 

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 requests recovery of the costs and the deferral balance or the end of 2018.  
Recovery of deferred costs will be addressed in a future IPUC proceeding.  Idaho Power anticipates that its participation in the 
Western EIM will commence in the spring of 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

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 

100

 
 
 
 
 
 
 
 
 
 
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 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 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, 2016, $500 
million in principal amount of Series K Notes remained available for issuance under the Indenture.

Mortgage:  As of December 31, 2016, Idaho Power could issue under its Indenture approximately $1.7 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.

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, 2016, IDACORP and Idaho Power executed the first extension agreement with the consent of all 
the lenders, extending the maturity date under both credit agreements to November 5, 2021.  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, 2016, no loans were outstanding under either IDACORP's or Idaho Power's facilities.  At December 31, 2016, 
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, 2016, and December 31, 2015:

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, 2016, the 
leverage ratios for IDACORP and Idaho Power were 45 percent and 47 percent, respectively.  Based on these restrictions, 
IDACORP’s and Idaho Power’s dividends were limited to $1.2 billion and $1.0 billion, respectively, at December 31, 2016.  
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, 
2016, 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, 2016, Idaho Power's common equity capital was 53 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.

7.  STOCK-BASED COMPENSATION

IDACORP has two share-based compensation plans -- the 2000 Long-Term Incentive and Compensation Plan (LTICP) and the 
1994 Restricted Stock Plan (RSP).  The RSP was terminated effective February 9, 2017.  The LTICP (for officers, key 
employees, and directors) permits the grant of stock options, restricted stock, performance shares, performance units, and 
several other types of stock-based awards.  At December 31, 2016, the maximum number of shares available under the LTICP 
and RSP were 934,781 and 15,796, respectively, excluding (i) issued but unvested performance-based restricted shares and (ii) 
issued but unvested time-based restricted shares.

Stock Awards:  Restricted stock awards have three-year vesting periods and entitle the recipients to dividends and voting rights.  
Unvested shares 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 restricted stock awards have three-year vesting periods and entitle the recipients to voting rights.  Unvested 
shares 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 150 
percent of the target award for awards granted prior to 2015 and from zero to 200 percent of the target award for awards granted 
in 2015 and 2016.  Dividends 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 share activity is presented below.  Idaho Power share amounts represent the 
portion of IDACORP amounts related to Idaho Power employees:

The total fair value of shares vested was $8.3 million in 2016, $8.3 million in 2015, and $6.6 million in 2014.  At December 31, 
2016, IDACORP had $5.0 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 $4.9 million.  These costs are expected to be recognized over a 
weighted-average period of 1.73 years.  IDACORP uses original issue and/or treasury shares for these awards.

In 2016, a total of 12,681 shares were awarded to directors at a grant date fair value of $70.96 per share.  Directors elected to 
defer receipt of 4,931 of these shares, which are being held as deferred stock units with dividend equivalents reinvested in 
additional stock units.

Compensation Expense:  The following table shows the compensation cost recognized in income and the tax benefits resulting 
from these plans, as well as the amounts allocated to Idaho Power for those costs associated with Idaho Power’s employees (in

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 $71 million at December 31, 2016, representing IERCo's one-third share of BCC's total 
reclamation obligation.  BCC has a reclamation trust fund set aside specifically for the purpose of paying these reclamation 
costs.  At December 31, 2016, the value of the reclamation trust fund was $78 million.  During 2016, the reclamation trust fund 
distributed approximately $6 million 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, 2016, 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, including the items described below.  Some of these claims, controversies, disputes, and 
other contingent matters 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.  In such cases, there may be a 
possible exposure to loss in excess of any amounts accrued. IDACORP and Idaho Power monitor those matters for 
developments that could affect the likelihood of a loss and the accrued amount, if any, and adjust the amount as appropriate.  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.   

Western Energy Proceedings 

High prices for electricity, energy shortages, and blackouts in California and in the western wholesale markets during 2000 and 
2001 caused numerous purchasers of electricity in those markets to initiate proceedings to consider requiring refunds and other 
forms of disgorgement from energy sellers.  Idaho Power and IESCo (as successor to IDACORP Energy L.P.) believe that the 
current state of the FERC's orders and the settlement releases they have obtained, including a settlement Idaho Power and 
IESCo executed in December 2016 and approved by the FERC relating to the California energy market proceedings, will 
eliminate or restrict potential future claims that might result from the remaining proceedings. As IDACORP and Idaho Power 
believe that their participation in the California and western wholesale market proceedings has effectively concluded, 
IDACORP and Idaho Power expect that these matters will not have a material adverse effect on their respective results of 
operations or financial condition in future periods.

Hoku Corporation Bankruptcy Claims 

On June 26, 2015, the trustee in the Hoku Corporation chapter 7 bankruptcy case (In Re: Hoku Corporation, United States 
Bankruptcy Court, District of Idaho, Case No. 13-40838 JDP) filed a complaint against Idaho Power, alleging that specified 

106

 
 
 
 
 
 
 
 
 
 
 
 
 
payments made by Hoku Corporation to Idaho Power in the six years prior to Hoku Corporation's bankruptcy filing in July 
2013 should be recoverable by the trustee as constructive fraudulent transfers.  Hoku Corporation was the parent entity of Hoku 
Materials, Inc., with which Idaho Power had an electric service agreement approved by the IPUC in March 2009.  Under the 
electric service agreement, Idaho Power agreed to provide electric service to a polysilicon production facility under 
construction by Hoku Materials in the state of Idaho.  Idaho Power also had agreements with Hoku Materials pertaining to the 
design and construction of apparatus for the provision of electric service to the polysilicon plant.  The trustee's complaint 
against Idaho Power requested recovery from Idaho Power in amounts up to approximately $36 million.  The complaint alleged 
that the payments made by Hoku Corporation to Idaho Power were subject to recovery by the trustee on the basis that Hoku 
Corporation was insolvent at the time of the payments and did not have any legal or equitable title in the polysilicon plant or 
liability for Hoku Materials' debts, and thus did not receive reasonably equivalent value for the payments it made for or on 
behalf of Hoku Materials. In September 2016, the bankruptcy judge issued an oral opinion granting Idaho Power’s and other 
parties’ motion for substantive consolidation of Hoku Corporation and Hoku Materials, which consolidated the bankruptcies of 
Hoku Corporation and Hoku Materials.  On December 20, 2016, the bankruptcy judge entered an order of dismissal, with 
prejudice, of the complaint against Idaho Power, which effectively ended Idaho Power’s participation in the adversary 
proceedings.  

Other Proceedings

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 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.  However, Idaho Power does believe that future capital investment 
for infrastructure and modifications to its electric system facilities could be significant to comply with 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.

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 2016, 2015, and 2014 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 
recorded value of these investments was approximately $78 million and $69 million at December 31, 2016 and 2015, 
respectively, and is reflected in Investments and in Company-owned life insurance on the consolidated balance sheets.

In 2017, IDACORP and Idaho Power expect to recognize as components of net periodic benefit cost $16.6 million from 
amortizing amounts recorded in accumulated other comprehensive income (or as a regulatory asset for the pension plan) as of 
December 31, 2016, relating to the pension plan and SMSP.  This amount consists of $13.5 million of amortization of net loss 
for the pension plan and $3.0 million of amortization of net loss and $0.1 million of amortization of prior service cost for the 
SMSP.

As of December 31, 2016, IDACORP's and Idaho Power's minimum required contributions to the pension plan are estimated to 
be zero in 2017, though Idaho Power plans to contribute between $20 million and $40 million to the pension plan during 2017 
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.

Medicare Act:  The Medicare Prescription Drug, Improvement and Modernization Act of 2003 was signed into law in 
December 2003 and established a prescription drug benefit under Medicare Part D, as well as a federal subsidy to sponsors of 
retiree health care benefit plans that provide a prescription drug benefit that is at least actuarially equivalent to Medicare’s 
prescription drug coverage.

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 8.3 percent in 2016 and is assumed to decrease to 6.8 percent in 2017, 5.3 percent in 2018, 5.2 percent in 2019 and to 
gradually decrease to 4.5 percent by 2096.  The assumed dental cost trend rate used to measure the expected cost of dental 
benefits covered by the plan was 5.0 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, 2016 (in thousands of 
dollars):

Plan Assets

Pension Asset Allocation Policy:  The target allocation and actual allocations at December 31, 2016, for the pension asset 
portfolio by asset class is set forth below:

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, core 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.

(1) The postretirement benefits assets are primarily life insurance contracts.

For the year ended December 31, 2016 and December 31, 2015, there were no material transfers into or out of Levels 1, 2, or 3 
other than the adoption of ASU 2015-07, Fair Value Measurement (Topic 820) - Disclosures for Investments in Certain Entities 
That Calculate Net Asset Value per Share (or Its Equivalent), which removed from the fair value hierarchy, investments for 
which the practical expedient is used to measure fair value at net asset value (NAV).  In prior years, certain investments were 

113

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
measured using NAV as a practical expedient for fair value, and these amounts were included as level 2 and 3 items in the fair 
value hierarchy.  The requirements of this ASU were adopted retrospectively; therefore, the 2015 amounts have been 
reclassified to conform to the 2016 presentation.  Because these amounts are no longer included in the fair value hierarchy as 
level 3 items, the level 3 reconciliations are no longer applicable and have been excluded from this footnote. 

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 commodites 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 $8 million, $7 million, and $7 million in 2016, 2015, and 2014, respectively.

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 benefit amounts included in other deferred credits on IDACORP’s and Idaho 
Power’s consolidated balance sheets at both December 31, 2016 and 2015, were $2 million.

12.  PROPERTY, PLANT AND EQUIPMENT AND JOINTLY-OWNED PROJECTS

At December 31, 2016, Idaho Power's construction work in progress balance of $405 million included relicensing costs of $249 
million for the Hells Canyon Complex (HCC), Idaho Power's largest hydroelectric complex.  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.  At December 31, 2016, Idaho 
Power's regulatory liability for collection of AFUDC relating to the HCC was $103 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, 2016 (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 $93 million in 2016, $93 million in 2015, and $79 million in 2014.

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 $8 million in 2016, $8 million in 2015, and $9 million in 2014.

IDACORP's consolidated VIE, Marysville, owns a hydroelectric plant with a net book value of approximately $16 million and 
$19 million at December 31, 2016 and 2015, 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.  In 2016, changes in 
estimates at the coal-fired generation facilities resulted in a net increase of $1.8 million in the recorded AROs. 

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 for the removal costs recorded 
as regulatory liabilities on IDACORP’s and Idaho Power’s consolidated balance sheets as of December 31, 2016 and 2015.

The following table presents the changes in the carrying amount of AROs (in thousands of dollars):

At the end of each reporting period, IDACORP and Idaho Power analyze securities in loss positions to determine whether they 
have experienced a decline in market value that is considered other-than-temporary.  At December 31, 2016 and December 31, 
2015, there were no indicators of other-than-temporary impairment related to IDACORP's and Idaho Power's investments.  

Investments in Affordable Housing

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.

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 

117

 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.

Settlement gains and losses on electricity swap contracts are recorded on the income statement in off-system sales or purchased 
power depending on the forecasted position being economically hedged by the derivative contract.  Settlement gains and losses 
on contracts for natural gas are reflected in fuel expense.  Settlement gains and losses on diesel derivatives are recorded in other 
operations and maintenance expense.  See Note 16 for additional information concerning the determination of fair value for 
Idaho Power’s assets and liabilities from price risk management activities.

At December 31, 2016, 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, 2016, was $0.3 million.  Idaho Power posted no cash 
collateral related to this amount.  If the credit-risk-related contingent features underlying these agreements were triggered on 
December 31, 2016, Idaho Power would have been required to pay or post collateral to its counterparties up to an additional 
$2.7 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.

119

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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, 2016 and 2015.

The following table presents information about IDACORP’s and Idaho Power’s assets and liabilities measured at fair value on a 
recurring basis as of December 31, 2016 and 2015 (in thousands of dollars):

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. 

The table below presents the carrying value and estimated fair value of financial instruments that are not reported at 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 IESCo, 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 Board of Directors and Shareholders of
IDACORP, Inc.
Boise, Idaho

We have audited the accompanying consolidated balance sheets of IDACORP, Inc. and subsidiaries (the “Company”) as of 
December 31, 2016 and 2015, 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, 2016.  Our audits also included the financial statement 
schedules listed in the Index at Item 8.  These financial statements and financial statement schedules are the responsibility of 
the Company’s management.  Our responsibility is to express an opinion on the financial statements and financial statement 
schedules based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial 
statements are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts 
and disclosures in the financial statements.  An audit also includes assessing the accounting principles used and significant 
estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits 
provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of 
IDACORP, Inc. and subsidiaries at December 31, 2016 and 2015, and the results of their operations and their cash flows for 
each of the three years in the period ended December 31, 2016, in conformity with accounting principles generally accepted in 
the United States of America.  Also, in our opinion, such financial statement schedules, when considered in relation to the basic 
consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
Company’s internal control over financial reporting as of December 31, 2016, 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 23, 2017 expressed an unqualified opinion on the Company’s internal control over financial 
reporting.

Power Company and subsidiary at December 31, 2016 and 2015, and the results of their operations and their cash flows for 
each of the three years in the period ended December 31, 2016, in conformity with accounting principles generally accepted in 
the United States of America.  Also, in our opinion, such financial statement schedule, when considered in relation to the basic 
consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
Company’s internal control over financial reporting as of December 31, 2016, 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 23, 2017 expressed an unqualified opinion on the Company’s internal control over financial 
reporting.

ITEM 9A.  CONTROLS AND PROCEDURES

The Chief Executive Officer and Chief Financial Officer of IDACORP, Inc., based on their evaluation of IDACORP, Inc.’s

IDACORP, Inc.’s disclosure controls and procedures are effective as of that date.

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, 2016.  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, 2016, 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, 2016 and issued a report, which appears on the next page and expresses an 
unqualified opinion on the effectiveness of IDACORP’s internal control over financial reporting as of December 31, 2016.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of
IDACORP, Inc.
Boise, Idaho

We have audited the internal control over financial reporting of IDACORP, Inc. and subsidiaries (the “Company”) as of 
December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission.  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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  
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.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s 
principal executive and principal financial officers, or persons performing similar functions, 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 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper 
management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely 
basis.  Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods 
are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of 
compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2016, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
consolidated financial statements and financial statement schedules as of and for the year ended December 31, 2016 of the 
Company and our report dated February 23, 2017 expressed an unqualified opinion on those financial statements and financial 
statement schedules.

concluded that Idaho Power Company's disclosure controls and procedures are effective as of that date.

Internal Control Over Financial Reporting - Idaho Power Company 

Management’s Annual Report on Internal Control Over Financial Reporting

The management of Idaho Power Company (Idaho Power) is responsible for establishing and maintaining adequate internal

Based on its assessment, management concluded that, as of December 31, 2016, Idaho Power’s internal control over financial 
reporting is effective based on those criteria.

Idaho Power’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, 2016 and issued a report which appears on the next page and expresses

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholder of
Idaho Power Company
Boise, Idaho

We have audited the internal control over financial reporting of Idaho Power Company and subsidiary (the “Company”) as of 
December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission.  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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  
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.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s 
principal executive and principal financial officers, or persons performing similar functions, 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 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper 
management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely 
basis.  Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods 
are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of 
compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2016, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
consolidated financial statements and financial statement schedule as of and for the year ended December 31, 2016 of the 
Company and our report dated February 23, 2017 expressed an unqualified opinion on those financial statements and financial 
statement schedule.

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 2016 and 2015, 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.

133

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.
