CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

In addition to the historical information contained in this report, this report contains (and oral communications made by IDACORP, Inc. (IDACORP) and Idaho Power Company (Idaho Power) 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, or future events, or performance, often, but not always, through the use of words or phrases such as "anticipates," "believes," "continues," "could," "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 this report, IDACORP's and Idaho Power's Annual Report on Form 10-K for the year ended December 31, 2018, particularly Part I, Item 1A - "Risk Factors" and Part II, Item 7 - "Management’s Discussion and Analysis of Financial Condition and Results of Operations" of that report, subsequent reports filed by IDACORP and Idaho Power with the U.S. Securities and Exchange Commission, and the following important factors:

the effect of decisions by the Idaho and Oregon public utilities commissions and the Federal Energy Regulatory Commission that impact Idaho Power's ability to recover costs and earn a return on investment;
the expense and risks associated with capital expenditures for utility infrastructure, and the timing and availability of cost recovery for such expenditures through customer rates, including the potential for the write-down or write-off of expenditures if not deemed prudent by regulators;
changes in residential, commercial, and industrial growth and demographic patterns within Idaho Power's service area, the loss or change in the business of significant customers, or the addition of new customers, and their associated impacts on loads and load growth, and the availability of regulatory mechanisms that allow for timely cost recovery through customer rates in the event of those changes;
the impacts of economic conditions, including inflation, interest rates, regulatory authorized returns on equity, supply costs, population growth or decline in Idaho Power's service area, changes in customer demand for electricity, revenue from sales of excess power, credit quality of counterparties and suppliers, and the collection of receivables;
unseasonable or severe weather conditions, wildfires, droughts, and other natural phenomena and natural disasters, including conditions and events associated with climate change, which affect customer demand, hydropower generation levels, repair costs, liability for damage caused by utility property, including from wildfires, and the availability and cost of fuel for generation plants or purchased power to serve customers;
advancement of self-generation, energy storage, grid-connected devices, and energy efficiency technologies that may affect Idaho Power's sale or delivery of electric power or introduce new cyber security risks;
changes in tax laws or related regulations or new interpretations of applicable laws by federal, state, or local taxing jurisdictions, the availability of tax credits, and the tax rates payable by IDACORP shareholders on common stock dividends;
adoption of, changes in, and costs of compliance with laws, regulations, and policies relating to the environment, natural resources, and threatened and endangered species, and the ability to recover associated increased costs through rates;
variable hydrological conditions and over-appropriation of surface and groundwater in the Snake River Basin, which may impact the amount of power generated by Idaho Power's hydropower facilities;
the ability to acquire fuel, power, and transmission capacity under reasonable terms, particularly in the event of unanticipated power demands, lack of physical availability, transportation constraints, or a credit downgrade;
accidents, fires (either affecting or caused by Idaho Power facilities or infrastructure), explosions, and mechanical breakdowns that may occur while operating and maintaining Idaho Power assets, which can cause unplanned outages, reduce generating output, damage the companies’ assets, operations, or reputation, subject the companies to third-party claims for property damage, personal injury, or loss of life, or result in the imposition of civil, criminal, and regulatory fines and penalties for which the companies may have inadequate insurance coverage;
the increased purchased power costs and operational challenges associated with purchasing and integrating intermittent renewable energy sources into Idaho Power's resource portfolio;
Table of Contents

disruptions or outages of Idaho Power's generation or transmission systems or of any interconnected transmission systems may constrain resources or cause Idaho Power to incur repair costs or purchase replacement power at increased costs;
the ability to obtain debt and equity financing or refinance existing debt when necessary and on favorable terms, which can be affected by factors such as credit ratings, volatility or disruptions in the financial markets, interest rate fluctuations, decisions by the Idaho or Oregon public utility commissions, and the companies' past or projected financial performance;
reductions in credit ratings, which could adversely impact access to debt and equity markets, increase borrowing costs, and require the posting of additional collateral to counterparties pursuant to credit and contractual arrangements;
the ability to enter into financial and physical commodity hedges with creditworthy counterparties to manage price and commodity risk, and the failure of any such risk management and hedging strategies to work as intended;
changes in actuarial assumptions, changes in interest rates, and the return on plan assets for pension and other post-retirement plans, which can affect future pension and other postretirement plan funding obligations, costs, and liabilities and the companies' cash flows;
the ability to continue to pay dividends based on financial performance and in light of contractual covenants and restrictions and regulatory limitations;
employee workforce factors, including the operational and financial costs of unionization or the attempt to unionize all or part of the companies' workforce, the impact of an aging workforce and retirements, the cost and ability to attract and retain skilled workers, and the ability to adjust the labor cost structure when necessary;
failure to comply with state and federal laws, regulations, and orders, including new interpretations and enforcement initiatives by regulatory and oversight bodies, which may result in penalties and fines and increase the cost of compliance, the nature and extent of investigations and audits, and the cost of remediation;
the inability to obtain or cost of obtaining and complying with required governmental permits and approvals, licenses, rights-of-way, and siting for transmission and generation projects and hydropower facilities;
the cost and outcome of litigation, dispute resolution, and regulatory proceedings, and the ability to recover those costs or the costs of resulting operational changes through insurance or rates, or from third parties;
the companies' failure to secure data or to comply with privacy laws or regulations, security breaches, or the disruption or damage to the companies' business, operations, or reputation resulting from cyber-attacks or related litigation or penalties, terrorist incidents or the threat of terrorist incidents, or other malicious acts, and acts of war;
unusual or unanticipated changes in normal business operations, including unusual maintenance or repairs, or the failure to successfully implement new technology solutions; and
adoption of or changes in accounting policies and principles, changes in accounting estimates, and new U.S. Securities and Exchange Commission or New York Stock Exchange requirements, or new interpretations of existing requirements.

Any forward-looking statement speaks only as of the date on which such statement is made. New factors emerge from time to time and it is not possible for management to predict all such factors, nor can it assess the impact of any such factor on the business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. IDACORP and Idaho Power disclaim any obligation to update publicly any forward-looking information, whether in response to new information, future events, or otherwise, except as required by applicable law.

IDACORP, INC. AND IDAHO POWER COMPANY
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
This Quarterly Report on Form 10-Q is a combined report of IDACORP, Inc. (IDACORP) and Idaho Power Company (Idaho Power). Therefore, these Notes to Condensed 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, sale, 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 (Jim Bridger plant) owned in part by Idaho Power (Jim Bridger plant).Power.
 
IDACORP’s significant other wholly-owned subsidiaries include IDACORP Financial Services, Inc. (IFS), an investor in affordable housing and other real estate investments, and Ida-West Energy Company (Ida-West), an operator of small hydropower generation projects that satisfy the requirements of the Public Utility Regulatory Policies Act of 1978 (PURPA).

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. 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. The effects of applying these regulatory accounting principles to Idaho Power's operations are discussed in more detail in Note 3 - "Regulatory Matters."

Financial Statements
 
In the opinion of management of IDACORP and Idaho Power, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary to present fairly each company's consolidated financial position as of JuneSeptember 30, 2019, consolidated results of operations for the three and sixnine months ended JuneSeptember 30, 2019 and 2018, and consolidated cash flows for the sixnine months ended JuneSeptember 30, 2019 and 2018. These adjustments are of a normal and recurring nature. These financial statements do not contain the complete detail or note disclosures concerning accounting policies and other matters that would be included in full-year financial statements and should be read in conjunction with the audited consolidated financial statements included in IDACORP’s and Idaho Power’s Annual Report on Form 10-K for the year ended December 31, 2018 (2018 Annual Report). The results of operations for the interim period are not necessarily indicative of the results to be expected for the full year. A change in management's estimates or assumptions could have a material impact on IDACORP's or Idaho Power's respective financial condition and results of operations during the period in which such change occurred.
 
Management Estimates
 
Management makes estimates and assumptions when preparing financial statements in conformity with generally accepted accounting principles. These estimates and assumptions include those related to rate regulation, retirement benefits, contingencies, asset impairment, income taxes, unbilled revenues, and bad debt. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial

statements and the reported amounts of revenues and expenses during the reporting period. These estimates involve judgments
Table of Contents

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.

New and Recently Adopted Accounting Pronouncements

Recently Adopted Accounting PronouncementsPronouncement

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842), intended to improve financial reporting on leasing transactions. The ASU requires lessees to recognize a right-of-use asset and lease liability on the balance sheet for most leases. In addition, the ASU revises the definition of a lease in regards to when an arrangement conveys the right to control the use of the identified asset under the arrangement. IDACORP and Idaho Power adopted ASU 2016-02 on January 1, 2019. The adoption did not have a material impact on their respective financial statements. Neither IDACORP nor Idaho Power has material agreements that meet the definition of a lease under ASU 2016-02.

Recent Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, to provide financial statement users with more information about expected credit losses on financial instruments and other commitments. The ASU revises the incurred loss impairment methodology to reflect current expected credit losses and requires consideration of a broader range of information to estimate credit losses. The new standard is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. IDACORP and Idaho Power are evaluating the impact of ASU 2016-13 on their respective financial statements, but the companies do not believe the adoption of the new standard will have a material impact on their respective financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,
to provide guidance on implementation costs incurred in a cloud computing arrangement that is a service contract. ASU 2018-15 aligns the accounting forrecognition of such implementation costs with the guidance on capitalizingaccounting for costs associated with developing or obtainingincurred to implement an internal-use software.software solution. However, the balance sheet line item for presentation of capitalized implementation costs for a cloud computing arrangement that is a service contract should be the same as that for the prepayment of fees related to the same arrangement, while capitalized implementation costs for internal-use software solutions are often included in property, plant, and equipment as an intangible asset. The new standard is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. IDACORP and Idaho Power are evaluating the impact of ASU 2018-15 on their respective financial statements, but the companies do not believe the adoption of the new standard will have a material impact on their respective financial statements.

2.  INCOME TAXES
 
In accordance with interim reporting requirements, IDACORP and Idaho Power use an estimated annual effective tax rate for computing their provisions for income taxes. An estimate of annual income tax expense (or benefit) is made each interim period using estimates for annual pre-tax income, income tax adjustments, and tax credits. The estimated annual effective tax rates do not include discrete events such as tax law changes, examination settlements, accounting method changes, or adjustments to tax expense or benefits attributable to prior years. Discrete events are recorded in the interim period in which they occur or become known. The estimated annual effective tax rate is applied to year-to-date pre-tax income to determine income tax expense (or benefit) for the interim period consistent with the annual estimate. In subsequent interim periods, income tax expense (or benefit) for the period is computed as the difference between the year-to-date amount reported for the previous interim period and the current period's year-to-date amount.

The increase in income tax expense for the sixnine months ended JuneSeptember 30, 2019, compared with the same period in 2018, was primarily due to the tax deduction for first mortgage bond redemption costs incurred in the second quarter of 2018.2018, the remeasurement of deferred taxes in the third quarter of 2018 due to income tax reform, lower excess deferred income tax reversal amounts, and other plant-related income tax return adjustments. On a net basis, Idaho Power’s estimate of its annual 2019 regulatory flow-through tax adjustments is comparable to 2018.

3. REGULATORY MATTERS
 
Included below is a summary of Idaho Power's most recent general rate cases and base rate changes, as well as other recent or pending notable regulatory matters and proceedings.

Idaho and Oregon General Rate Cases

Idaho Power's current base rates result from orders from the Idaho Public Utilities Commission (IPUC) and Public Utility Commission of Oregon (OPUC). The commissions approve settlement stipulations that generally provide for cost recovery and an authorized rate of return on their respective Idaho-jurisdiction and Oregon-jurisdiction rate bases. Idaho Power's most recent general rate cases in Idaho and Oregon were filed during 2011 and Idaho Power filed2011. In 2012, large single-issue rate cases 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.Oregon. In 2014, Idaho Power reset its base-rate power supply expenses in the Idaho jurisdiction for purposes of updating the collection of costs through retail rates, but without a resulting net increase in rates. The IPUC and OPUC have also approved smaller base rate changes in single issue cases subsequent to 2014.

Between general rate cases, Idaho Power relies upon customer growth, a fixed cost adjustment mechanism, 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. Also, Idaho Power may seek approval for additions to rate base or changes to base rates through other regulatory proceedings outside of a general rate case. For more information on the Idaho and Oregon general rate cases and base rate adjustments, refer to Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2018 Annual Report.

Idaho Settlement Stipulations

In October 2014, the IPUC issued an order approving an extension, with modifications, of the terms of a December 2011 Idaho settlement stipulation for the period from 2015 through 2019, or until the terms are otherwise modified or terminated by order of the IPUC (October 2014 Idaho Earnings Support and Sharing Settlement Stipulation). A May 2018 Idaho settlement stipulation related to tax reform (May 2018 Idaho Tax Reform Settlement Stipulation) provides for the extension of the October 2014 Idaho Earnings Support and Sharing Settlement Stipulation beyond the initial termination date of December 31, 2019, with modified terms related to the accumulated deferred investment tax credits (ADITC) and revenue sharing mechanism to become effective beginning January 1, 2020. The October 2014 Idaho Earnings Support and Sharing Settlement Stipulation and the May 2018 Idaho Tax Reform Settlement Stipulation are described in Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2018 Annual Report and include provisions for the accelerated amortization of ADITC to help achieve a minimum 9.5 percent (9.4 percent after 2019) return on year-end equity in the Idaho jurisdiction (Idaho ROE).
Table of Contents

The settlement stipulations also provide for the potential sharing between Idaho Power and Idaho customers of Idaho-jurisdictional earnings in excess of 10.0 percent of Idaho ROE.

Based on its estimate of full-year 2019 Idaho ROE, in both the secondthird quarter and first sixnine months of 2019, Idaho Power recorded no0 additional ADITC amortization or provision against current revenues for sharing of earnings with customers for 2019 under the October 2014 Idaho Earnings Support and Sharing Settlement Stipulation. DuringAccordingly, at September 30, 2019, the second quarter of 2018, Idaho Power reversed the $0.5full $45 million of additional ADITC amortizationremains available for future use under the terms of the October 2014 Idaho Earnings Support and Sharing Settlement Stipulation. Idaho Power recorded a $1.5 million provision against revenues for sharing of earnings with customers during the firstthird quarter of 2018, as actual financial results exceededbased on its then-current estimate of full-year 2018 Idaho Power's early estimates.ROE.

Idaho Power Cost Adjustment Mechanisms

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 wholesale energy 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 sheet 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.

In May 2019, the IPUC approved a $50.1 million net decrease in Idaho-jurisdiction power cost adjustment (PCA) revenues, effective for the 2019-2020 PCA collection period from June 1, 2019 to May 31, 2020. The net decrease in PCA revenues reflects reduced power supply costs due to higher-than-expected wholesale energy sales and positive results from natural gas hedging activities, which combined to reduce actual net power supply costs for the 2018-2019 PCA year (April 2018 through
Table of Contents

March 2019). The net decrease in PCA revenues for the 2019-2020 PCA collection period also includes a $5.0 million credit to customers for sharing of 2018 earnings under the October 2014 Idaho Earnings Support and Sharing Settlement Stipulation and a $2.7 million credit for income tax reform benefits related to Idaho Power's open access transmission tariff (OATT) rate under the May 2018 Idaho Tax Reform Settlement Stipulation. In addition, the net decrease in PCA revenues reflects benefits from Idaho Power's participation in the energy imbalance market implemented in the western United States (Western EIM). Previously, in May 2018, the IPUC issued an order approving a $30.4 million net decrease in PCA rates, effective for the 2018-2019 PCA collection period from June 1, 2018, to May 31, 2019. The net decrease in PCA rates included a $7.8 million one-time benefit for income tax savings from January 1, 2018 to May 31, 2018, as well as those related to Idaho Power's OATT rate. The remaining net decrease in PCA rates for the 2018-2019 PCA collection period was primarily due to better-than-expected actual water conditions for the 2017-2018 PCA year (April 2017 through March 2018), which resulted in additional low-cost hydropower being available to reduce net power supply costs. 

Idaho Fixed Cost Adjustment Mechanism

The Idaho jurisdiction fixed cost adjustment (FCA) mechanism, applicable to Idaho residential and small general service customers, is designed to remove a portion of 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. Under Idaho Power's current rate design, Idaho Power recovers a portion of fixed costs through the variable kilowatt-hour charge, which may result in over-collection or under-collection of fixed costs. To return over-collection to customers or to collect under-collection from customers, the FCA mechanism allows Idaho Power to accrue, or defer, the difference between the authorized fixed-cost recovery amount per customer and the actual fixed costs per customer recovered by Idaho Power during the year. Any annual increase in the FCA recovery may be capped at 3 percent of base revenue at the discretion of the IPUC, with any excess deferred for collection in a subsequent year. In May 2019, the IPUC approved an increase of $19.2 million in recovery from the FCA from $15.6 million to $34.8 million, with new rates effective for the period from June 1, 2019 to May 31, 2020. Previously, in May 2018, the IPUC issued an order approving a decrease of $19.4 million in the FCA from $35.0 million to $15.6 million, with rates effective for the period from June 1, 2018 to May 31, 2019.

Valmy Exit Agreement and Base Rate Adjustment Approval Request

In February 2019, Idaho Power reached an agreement with NV Energy that facilitates the planned end of Idaho Power's participation in coal-fired operations at units 1 and 2 of its jointly-owned North Valmy coal-fired power plant (Valmy Plant) in 2019 and 2025, respectively. In May 2019, the IPUC issued an order approving the Valmy Plant agreement and allowing Idaho Power to recover through customer rates the $1.2 million incremental annual levelized revenue requirement associated with
Table of Contents

required Valmy Plant investments and other exit costs, effective June 1, 2019 through December 31, 2028.

In JulyOctober 2019, Idaho Power filed an application with the OPUC requesting that the OPUC approveapproved the Valmy Plant agreement and authorizeauthorized Idaho Power to adjust customer rates in Oregon, effective January 1, 2020, to reflect a decrease in the annual levelized revenue requirement of $3.2 million. As ofmillion, which mostly relates to the date of this report, the application remains pending.associated decrease in depreciation expense and other costs.

(1) The FCA mechanism is an alternative revenue program in the Idaho jurisdiction and does not represent revenue from contracts with customers.
(2) As part of its January 30, 2009, general rate case order, the IPUC is allowing Idaho Power to recover a portion of the allowance for funds used during construction (AFUDC) on construction work in progress related to the Hells Canyon Complex (HCC) relicensing process, even though the relicensing process is not yet complete and the costs have not been moved to electric plant in service. Idaho Power is collecting $8.8 million annually in the Idaho jurisdiction but is deferring revenue recognition of the amounts collected until the license is issued and the accumulated license costs approved for recovery are placed in service.

Alternative Revenue Programs and Other Revenues

While revenues from contracts with customers make up most of Idaho Power’s revenues, the IPUC has authorized the use of an additional regulatory mechanism, the Idaho FCA mechanism, which may increase or decrease tariff-based rates billed to customers.customer rates. The Idaho FCA mechanism is described in "NoteNote 3 - Regulatory"Regulatory Matters." The FCA mechanism revenues include only the initial recognition of FCA revenues when revenuesthey meet the regulator-specified conditions for recognition. Revenue from contracts with
Table of Contents

customers excludes the portion of the tariff price representing FCA revenues that Idaho Power initially recorded in prior periods when revenues met regulator-specified conditions. When Idaho Power includes those amounts in the price of utility service billed to customers, Idaho Power records such amounts as recovery of the associated regulatory asset or liability and not as revenues.

Derivative revenues include gains from settled electricity swaps and sales of electricity under forward sales contracts that are bundled with renewable energy credits. Related to these forward sales, Idaho Power simultaneously enters into forward purchases of electricity for the same quantity at the same location, which are recorded in purchased power on the condensed consolidated statements of income. For more information on settled electricity swaps, see Note 11 - "Derivatives."

5. LONG-TERM DEBT

5.Pollution Control Tax-Exempt Bonds

In August 2019, Idaho Power purchased and remarketed two of its outstanding series of pollution control tax-exempt bonds, one in the aggregate principal amount of $49.8 million issued in 2003 by Humboldt County, Nevada and due in 2024, and the other in the aggregate principal amount of $116.3 million issued in 2006 by Sweetwater County, Wyoming and due in 2026. The bonds were remarketed with substantially the same terms, but with lower term interest rates. The term interest rate of the series due in 2024 decreased from 5.15 percent to 1.45 percent and the term interest rate of the series due in 2026 decreased from 5.25 percent to 1.70 percent.

6. COMMON STOCK
 
IDACORP Common Stock
 
During the sixnine months ended JuneSeptember 30, 2019, IDACORP granted 70,419 restricted stock unit awards to employees and issued 6,396 shares of common stock to directors, but made no0 original issuances of shares of common stock pursuant to the IDACORP, Inc. 2000 Long-Term Incentive and Compensation Plan. As directed by IDACORP, plan administrators of the IDACORP, Inc. Dividend Reinvestment and Stock Purchase Plan and Idaho Power Company Employee Savings Plan used market purchases of IDACORP common stock, as opposed to original issuance of common stock from IDACORP, to acquire shares of IDACORP common stock for the plans. However, IDACORP may determine at any time to use original issuances of common stock under those plans.

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 JuneSeptember 30, 2019, the leverage ratios for IDACORP and Idaho Power were 43 percent and 45 percent, respectively. Based on these restrictions, IDACORP’s and Idaho Power’s dividends were limited to $1.4$1.5 billion and $1.2$1.3 billion, respectively, at JuneSeptember 30, 2019. 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 IDACORP and Idaho Power from any material subsidiary. At JuneSeptember 30, 2019, IDACORP and Idaho Power were in compliance with those financial covenants.
 
Table of Contents

Idaho Power’s Revised 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 JuneSeptember 30, 2019, Idaho Power's common equity capital was 55 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 no0 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.

7.8. COMMITMENTS
 
Purchase Obligations
 
During the sixnine months ended JuneSeptember 30, 2019, IDACORP's and Idaho Power's contractual obligations, outside the ordinary course of business, did not change materially from the amounts disclosed in the notes to the consolidated financial statements in the 2018 Annual Report, except that Idaho Power entered into four new replacement contracts for expiring power purchase agreements with hydropower PURPA-qualifying facilities and one new agreement with a solar PURPA-qualifying facility, which increased Idaho Power's contractual purchase obligations by approximately $24 million over the 20-year terms of the contracts.

Also, in March 2019, Idaho Power signed a 20-year power purchase agreement, pending regulatory approval by the IPUC and OPUC, to purchase the output from a 120 megawattplanned 120-megawatt solar facility proposed to be constructed by a third party. Thefacility. If approved, the agreement would increase contractual obligations by $136 million over the 20-year term. In October 2019, Idaho Power exercised its right under the power purchase agreement to negotiate during the fourth quarter of this year for the acquisition by Idaho Power or its affiliates of the right to own the planned 120-megawatt solar facility. If an acquisition agreement is reached and the power purchase agreement is approved by the IPUC and OPUC, it could affect the net impact on Idaho Power or its affiliates of the contractual obligation related to the 20-year power purchase agreement described above.

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 $58.3 million at JuneSeptember 30, 2019, representing IERCo's one-third share of BCC's total reclamation obligation of $175.0 million. BCC has a reclamation trust fund set aside specifically for the purpose of paying these
Table of Contents

reclamation costs. At JuneSeptember 30, 2019, the value of BCC's reclamation trust fund was $125.9$126.4 million. During the sixnine months ended JuneSeptember 30, 2019, the reclamation trust fund made no0 distributions for reclamation activity costs associated with the BCC surface mine. BCC periodically assesses the adequacy of the reclamation trust fund and its estimate of future reclamation costs. To ensure that the reclamation trust fund maintains adequate reserves, BCC has the ability to, and does, add a per-ton surcharge to coal sales, all of which are made to the Jim Bridger plant. Because of the existence of the fund and the ability to apply a per-ton surcharge, the estimated fair value of this guarantee is minimal.

In May 2019, the state of Wyoming enacted legislation that limits a mine operator's maximum amount of self-bonding. Idaho Power and the co-owners of BCC have 18 monthsuntil December 2020 to comply with the new regulations, which would reduce the portion of Idaho Power's guarantee of reclamation activities and obligations at BCC that Idaho Power is allowed to self-bond. As of the date of this report, Idaho Power believes the cost of any insurance, third-party assurance, or additional collateral that might be required for this guarantee due to the new law would be immaterial to the companies' consolidated financial statements.
 
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 JuneSeptember 30, 2019, 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 condensed consolidated balance sheets with respect to these indemnification obligations.

8.9. CONTINGENCIES
 
IDACORP and Idaho Power have in the past and expect in the future to become involved in various claims, controversies, disputes, and other contingent matters, some of which involve litigation and regulatory or other contested proceedings. The ultimate resolution and outcome of litigation and regulatory proceedings is inherently difficult to determine, particularly where (a) the remedies or penalties sought are indeterminate, (b) the proceedings are in the early stages or the substantive issues have not been well developed, or (c) the matters involve complex or novel legal theories or a large number of parties. In accordance with applicable accounting guidance, IDACORP and Idaho Power, as applicable, establish an accrual for legal proceedings when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable. If the loss contingency at issue is not both probable and reasonably estimable, IDACORP and Idaho Power do not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. As of the date of this report, IDACORP's and Idaho Power's accruals for loss contingencies are not material to their financial statements as a whole; however, future accruals could be material in a given period. IDACORP's and Idaho Power's determination is based on currently available information, and estimates presented in financial statements and other financial disclosures involve significant judgment and may be subject to significant uncertainty. For matters that affect Idaho Power’s operations, Idaho Power intends to seek, to the extent permissible and appropriate, recovery through the ratemaking process of costs incurred, although there is no assurance that such recovery would be granted.
Table of Contents


IDACORP and Idaho Power are parties to legal claims and legal and regulatory actions and proceedings in the ordinary course of business and, as noted above, record an accrual for associated loss contingencies when they are probable and reasonably estimable. In connection with its utility operations, Idaho Power is subject to claims by individuals, entities, and governmental agencies for damages for alleged personal injury, property damage, and economic losses relating to the company’s provision of electric service and the operation of its generation, transmission, and distribution facilities. Some of those claims relate to electrical contacts, service quality, property damage, and wildfires. In recent years, utilities in the western United States have been subject to significant liability for personal injury, loss of life, property damage, trespass, and economic losses, and in some cases, punitive damages and criminal charges, associated with wildfires that originated from utility property, most commonly transmission and distribution lines. In recent years, Idaho Power has regularly received claims by both governmental agencies and private landowners for damages for fires allegedly originating from Idaho Power’s transmission and distribution system. As of the date of this report, the companies believe that resolution of existing claims will not have a material adverse effect on their respective consolidated financial statements. Idaho Power is also actively monitoring various pending environmental regulations and executive orders related to environmental matters that may have a significant impact on its future operations. Given uncertainties regarding the outcome, timing, and compliance plans for these environmental matters, Idaho Power is unable to estimate the financial impact of these regulations.

10. BENEFIT PLANS

Idaho Power has a noncontributory defined benefit pension plan (pension plan) and two nonqualified defined benefit plans for certain senior management employees called the Security Plan for Senior Management Employees I and Security Plan for Senior Management Employees II (collectively,(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 the pension plan are based on years of service and the employee’s final average earnings. Idaho Power also 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. The table below shows the components of net periodic benefit costs for the pension, SMSP, and postretirement benefits plans for the three months ended JuneSeptember 30, 2019 and 2018 (in thousands).

 (1) Net periodic benefit costs for the pension plan are recognized for financial reporting based upon the authorization of each regulatory jurisdiction in which Idaho Power operates. Under IPUC order, the Idaho portion of net periodic benefit cost is recorded as a regulatory asset and is recognized in the income statement as those costs are recovered through rates.
 (2) Of total net periodic benefit cost recognized for financial reporting, $8.4$12.6 million and $8.2$12.3 million, respectively, were recognized in "Other operations and maintenance" and $5.5$8.2 million and $5.8$8.7 million, respectively, were recognized in "Other expense, net" on the condensed consolidated statements of income of the companies for the sixnine months ended JuneSeptember 30, 2019 and 2018.

Idaho Power has no0 minimum contribution requirement to its defined benefit pension plan in 2019. However, during the sixnine months ended JuneSeptember 30, 2019, Idaho Power made $10$40 million of discretionary contributions to its defined benefit pension plan, in a continued effort to 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. The primary impact of pension contributions is on the timing of cash flows, as the timing of cost recovery lags behind contributions.

Idaho Power also has an Employee Savings Plan that complies with Section 401(k) of the Internal Revenue Code and covers substantially all employees. Idaho Power matches specified percentages of employee contributions to the Employee Savings Plan.

10.11. DERIVATIVE FINANCIAL INSTRUMENTS
 
Commodity Price Risk
 
Idaho Power is exposed to market risk relating to electricity, natural gas, and other fuel commodity prices, all of which are heavily influenced by supply and demand. Market risk may be influenced by market participants’ nonperformance of their contractual obligations and commitments, which affects the supply of or demand for the commodity. Idaho Power uses derivative instruments, such as physical and financial forward contracts, for both electricity and fuel to manage the risks relating to these commodity price exposures. The primary objectives of Idaho Power’s energy purchase and sale activity are to meet the demand of retail electric customers, maintain appropriate physical reserves to ensure reliability, and make economic use of temporary surpluses that may develop.
 
All of Idaho Power's derivative instruments have been entered into for the purpose of economically hedging forecasted purchases and sales, though none of these instruments have been designated as cash flow hedges. Idaho Power offsets fair value amounts recognized on its balance sheet and applies collateral related to derivative instruments executed with the same counterparty under the same master netting agreement. Idaho Power does not offset a counterparty's current derivative contracts with the counterparty's long-term derivative contracts, although Idaho Power's master netting arrangements would allow current and long-term positions to be offset in the event of default. Also, in the event of default, Idaho Power's master netting arrangements would allow for the offsetting of all transactions executed under the master netting arrangement. These types of transactions may include non-derivative instruments, derivatives qualifying for scope exceptions, receivables and payables arising from settled positions, and other forms of non-cash collateral (such as letters of credit). These types of transactions are excluded from the offsetting presented in the derivative fair value and offsetting table that follows.

(1) Excludes unrealized gains or losses on derivatives, which are recorded on the balance sheet as regulatory assets or regulatory liabilities.

Settlement gains and losses on electricity swap contracts are recorded on the income statement in operating revenues 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 1112 - "Fair Value Measurements" for additional information concerning the determination of fair value for Idaho Power’s assets and liabilities from price risk management activities.

Credit Risk
 
At JuneSeptember 30, 2019, 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
Table of Contents

gas, contracts are usually under North American Energy Standards Board contracts, and financial transactions are usuallygenerally under International Swaps and Derivatives Association, Inc.standardized industry 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 Idaho Power 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 JuneSeptember 30, 2019, was $4.6$2.8 million. Idaho Power posted $1.8$1.5 million cash collateral related to this amount. If the credit-risk-related contingent features underlying these agreements were triggered on JuneSeptember 30, 2019, Idaho Power would have been required to pay or post collateral to its counterparties up to an additional $4.6$5.9 million to cover the open liability positions as well as completed transactions that have not yet been paid.

12. 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 condensed 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:
Table of Contents

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.
 
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 no0 transfers between levels or material changes in valuation techniques or inputs during the sixnine months ended JuneSeptember 30, 2019.

The table below presents information about IDACORP’s and Idaho Power’s assets and liabilities measured at fair value on a recurring basis as of JuneSeptember 30, 2019, and December 31, 2018 (in thousands).

 (1) Holding company only. Does not include amounts held by Idaho Power.

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 derivatives are valued using New York Mercantile Exchange (NYMEX) and Intercontinental Exchange (ICE)ICE pricing, adjusted for location basis, which are also quoted under NYMEX and ICE pricing. Equity securities consist of employee-directed investments related to an executive deferred compensation plan and actively traded money market and exchange traded funds related to the SMSP. The investments are measured using quoted prices in active markets and are held in a Rabbi trust.

(1) Notes receivable and long-term debt are categorized as Level 3 and Level 2, respectively, of the fair value hierarchy, as defined earlier in this Note 1112 - "Fair Value Measurements."

Notes receivable are related to Ida-West and are valued based on unobservable inputs, including discounted cash flows, which are partially based on forecasted hydropower conditions. Long-term debt is not traded on an exchange and is valued using quoted rates for similar debt in active markets. Carrying values for cash and cash equivalents, deposits, customer and other receivables, notes payable, accounts payable, interest accrued, and taxes accrued approximate fair value.

12.13. 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 hydropower generation projects, 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 reconciles this information to total enterprise amounts (in thousands).

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 Idaho Public Utilities Commission (IPUC), Public Utility Commission of Oregon (OPUC), and Federal Energy Regulatory Commission (FERC). Idaho Power generates revenues and cash flows primarily from the sale and distribution of electricity to customers in its Idaho and Oregon service territories, as well as from the wholesale sale and transmission of electricity. Idaho Power 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 Idaho Energy Resources Co. (IERCo), a joint venturer in Bridger Coal Company (BCC), which mines and supplies coal to the Jim Bridger generating plant (Jim Bridger plant) owned in part by Idaho Power (Jim Bridger plant).Power. IDACORP’s other significant subsidiaries include IDACORP Financial Services, Inc., an investor in affordable housing and other real estate investments, and Ida-West Energy Company, an operator of small hydropower generation projects that satisfy the requirements of the Public Utility Regulatory Policies Act of 1978 (PURPA).

EXECUTIVE OVERVIEW

Management's Outlook and Company Initiatives

In the 2018 Annual Report, IDACORP's and Idaho Power's management included a brief overview of their business strategies for the companies for 2019 and beyond, under the heading "Executive Overview" in the MD&A. As of the date of this report, management's outlook and strategy remain consistent with that discussion. Most notably:

Idaho Power continues to expect positive customer growth in its service area, and continues to participate in and support state and local economic development initiatives aimed at responsible and sustainable growth. During the first sixnine months of 2019, Idaho Power's customer count grew by nearly 6,800over 10,700 customers, and for the twelve months ended JuneSeptember 30, 2019, the customer growth rate was 2.52.6 percent.
In 2019, Idaho Power achieved its highest ever residential customer satisfaction score, the highest of any investor-owned utility in the nation, as rated by an independent third party.
In February 2019, Idaho Power reached an agreement with NV Energy that facilitates the planned end of Idaho Power's participation in coal-fired operations at units 1 and 2 of its jointly-owned North Valmy coal-fired power plant (Valmy Plant) in 2019 and 2025, respectively. The IPUC and OPUC issued orders approving the Valmy Plant agreement in May and October 2019, respectively.
In March 2019, Idaho Power announced its "Clean Today, Cleaner Tomorrow.™" goal to provide its customers with 100-percent clean energy by 2045.
Idaho Power anticipates substantial capital investments, with expected total capital expenditures of approximately $1.5 billion over the five-year period from 2019 (including the expenditures incurred so far in 2019) through 2023.
Idaho Power continues to execute on its four strategic areas: growing to enhance financial strength, improving Idaho Power's core business, enhancing Idaho Power's brand, and focusing on safety and employee engagement.
Idaho Power continues to focus on timely recovery of costs and earning a reasonable return on investment, including working to evaluate and ensure that its rate design and regulatory mechanisms properlymore closely reflect the cost to provide electric service.

In February 2019, Idaho Power reached an agreement with NV Energy that facilitates the planned end of Idaho Power's participation in coal-fired operations at units 1 and 2 of its jointly-owned North Valmy coal-fired power plant (Valmy Plant) in 2019 and 2025, respectively.

Net Income - SecondThird Quarter 2019
IDACORP's net income decreased $9.1$12.3 million for the secondthird quarter of 2019 compared with the secondthird quarter of 2018, primarily due to lower net income at Idaho Power.
Customer growth increased operating income by $4.2$5.5 million in the secondthird quarter of 2019 compared with the secondthird quarter of 2018, as the number of Idaho Power customers grew by 2.5approximately 14,250, or 2.6 percent, during the twelve months ended JuneSeptember 30, 2019. SalesLower sales volumes on a per-customer basis decreased operating income by $13.4$8.6 million in the secondthird quarter of 2019 compared with the secondthird quarter of 2018. Greater2018, as greater precipitation in Idaho Power's service area led agricultural irrigation customers to use 206 percent less energy per customer to operate irrigation pumps. Also, residential and commercial customers used less energy per customer for coolingair conditioning purposes, primarily due to cooler temperatures. more moderate temperatures in the third quarter of 2019 compared with the third quarter of 2018.

The decrease in residential sales volumes per customer was mostlypartially offset by the FCA mechanism (applicable to residential and small general service customers), which increased revenues in the third quarter by $1.8$1.7 million.
Table of Contents


The net decrease in retail revenues per megawatt-hour (MWh) decreased operating income by $7.0$1.0 million in the secondthird quarter of 2019 compared with the secondthird quarter of 2018. The settlement stipulations approved by the IPUC and OPUC during the second quarter of 2018 relating to income tax reform reduced revenues in the second quarter of 2019 more significantly than in the second quarter of 2018. To a lesser extent, changes in the customer sales mix decreased the retail revenues per MWh as volumes sold to residential, commercial, and irrigation customers made up a lesser portion of the customer sales mix than industrial customers in the second quarter of 2019 compared with the second quarter of 2018. Residential, commercial, and irrigation customers generally pay a higher per-MWh rate than industrial customers.

During the second quarter of 2019, transmission wheeling-related revenues decreased $2.0 million compared with the second quarter of 2018, largely due to a decrease in Idaho Power's open access transmission tariff (OATT) rates that became effective in October 2018.

Other O&M expenses were $5.3 million lower in the second quarter of 2019 compared with the second quarter of 2018. Other O&M expenses related to Idaho Power's hydropower generation decreased $1.1 million, due primarily to fewer maintenance projects at hydropower locations in the second quarter of 2019 compared with the second quarter of 2018. Labor and benefit costs decreased $1.5 million, primarily related to the levels of accruals for variable employee-related costs. As provided by the settlement stipulation approved by the IPUC in 2018 related to income tax reform, O&M expensesretail revenues per MWh in the secondthird quarter of 2018 included $1.12019 were reduced by $2.9 million of non-cash accruals for future amortization expense ofrelated to regulatory deferrals that would otherwise be a future liability of Idaho customers. In the third quarter of 2018, the corresponding $2.9 million was recorded as other O&M expense for the amortization of specified deferrals. The decrease in retail revenues per MWh from these non-cash accruals was partially offset by changes in customer mix, as volumes sold to residential customers in the third quarter of 2019 made up a greater portion of the customer sales mix compared with the third quarter of 2018. Residential customers generally pay a higher per-MWh rate than other customers.

During the third quarter of 2019, transmission wheeling-related revenues decreased $5.1 million compared with the third quarter of 2018. Lower hydropower generation by other utilities in the Pacific Northwest and more moderate summer temperatures throughout the region led to lower wheeling volumes during the third quarter of 2019. Also, Idaho Power's open access transmission tariff (OATT) rates decreased in October 2018.

Other O&M expenses were $4.4 million lower in the third quarter of 2019 compared with the third quarter of 2018, due to a $1.6 million decrease in labor and benefit costs and the $2.9 million of non-cash amortization expense of regulatory deferrals recorded in the third quarter of 2018 pursuant to the settlement stipulation approved by the IPUC in 2018 related to income tax reform.

Under the Idaho regulatory settlement stipulation approved in October 2014, Idaho Power recorded a $1.5 million provision against revenues for sharing of earnings with customers during the third quarter of 2018, based on its estimate of full-year 2018 return on year-end equity in the Idaho jurisdiction (Idaho ROE). No such provision was recorded in the third quarter of 2019.

Overall, Idaho Power operating income decreased by $1.0 million for the third quarter of 2019 compared with the third quarter of 2018.

Based on its estimate of full-year 2019 Idaho ROE, in the third quarter of 2019 Idaho Power recorded no additional accumulated deferred investment tax credits (ADITC) amortization for 2019 under the Idaho regulatory settlement stipulation approved in October 2014.

During the third quarter of 2018, Idaho Power recorded tax benefits for a $5.7 million remeasurement of deferred taxes resulting from income tax reform. There was no such remeasurement in the third quarter of 2019. Also, the third quarter of 2018 included a benefit from plant-related income tax return adjustments, which are generally recorded during the third quarter each year upon completion of the prior year tax return, which reduced Idaho Power's income tax expense in the third quarter of 2018. These items, combined with lower excess deferred income tax reversal amounts, resulted in higher income tax expense in the third quarter of 2019 compared with the third quarter of 2018.

Net Income - Year-to-Date 2019

IDACORP's net income decreased $2.6$15.0 million for the first halfnine months of 2019 compared with the same period of 2018, primarily due to lower net income at Idaho Power.
Customer growth increased operating income by $8.2$14.1 million in the first halfnine months of 2019 compared with the first halfnine months of 2018. SalesLower sales volumes on a per-customer basis decreased operating income by $10.4$19.4 million in the first halfnine months of 2019 compared with the first halfnine months of 2018, primarily due to lower irrigation, residential, and commercial revenues in the second quarterand third quarters of 2019. Greater precipitation in Idaho Power's service area led agricultural irrigation customers to use 12 percent less energy per customer to operate irrigation pumps during the first nine months of 2019. Also, residential and commercial customers used less energy per customer for air conditioning purposes during the second and third quarters of 2019, as described above.primarily due to more moderate temperatures. The lower sales volumes on a per-customer basis in the second quarterand third quarters of 2019 were partially offset by a 3 percent increase in sales volumes per residential customer in the first quarter of 2019 compared with the first quarter of 2018, as colder temperatures led residential customers to use more energy for heating. The decrease in residential sales volumes per customer was partially offset by the FCA mechanism (applicable to residential and small general service customers), which increased revenues by $1.2 million.
The net decrease in retail revenues per MWh decreased operating income by $4.3$1.6 million in the first halfnine months of 2019 compared with the first half of 2018, due primarily to the effects of the settlement stipulations approved by the IPUC and OPUC during the second quarter of 2018 related to income tax reform noted above.

During the first half of 2019, Idaho Power benefited from a $2.0 million increase in transmission wheeling-related revenue, compared with the first halfsame period of 2018. This change was largely due to an increase in wheeling-related volumes driven by regional wholesale energy market activity in the first quarter of 2019, partially offset by a decrease in Idaho Power's OATT rates that became effective in October 2018.

Other O&M expenses were $2.6 million lower in the first half of 2019 compared with the first half of 2018. Other O&M expenses related to Idaho Power's hydropower generation decreased $2.3 million, due primarily to fewer maintenance projects at hydropower locations in the first half of 2019. As provided by the settlement stipulation approved by the IPUC in 2018 related to income tax reform, O&M expensesretail revenues per MWh in the first halfnine months of 2018 included $1.12019 were reduced by $5.8 million of non-cash accruals

for future amortization expense ofrelated to regulatory deferrals that would otherwise be a future liability of Idaho customers. In the first nine months of 2018, a corresponding $4.0 million of non-cash accruals were appropriately recorded as other O&M expense for the amortization of specified deferrals. The decrease in retail revenues per MWh from these non-cash accruals was partially offset by changes in customer mix, as volumes sold to residential customers in the first nine months of 2019 made up a greater portion of the customer sales mix compared with the first nine months of 2018. Residential customers generally pay a higher per-MWh rate than other customers.

During the first nine months of 2019, transmission wheeling-related revenue decreased $3.1 million compared with the first nine months of 2018. Lower hydropower generation by other utilities in the Pacific Northwest and more moderate summer temperatures throughout the region during the third quarter of 2019, offset partially by greater regional market activity in early 2019, led to lower wheeling volumes during the first nine months of 2019 compared with the first nine months of 2018. Also, Idaho Power's OATT rates decreased in October 2018.
Other O&M expenses were $7.0 million lower in the first nine months of 2019 compared with the first nine months of 2018. Other O&M expenses related to Idaho Power's hydropower generation decreased $2.0 million, due primarily to fewer maintenance projects at hydropower locations in the first nine months of 2019. Also, labor and benefit costs decreased $1.9 million. Other O&M expenses in the first nine months of 2018 included $4.0 million of non-cash amortization expense of regulatory deferrals pursuant to the settlement stipulation approved by the IPUC in 2018 related to income tax reform.

Based on its estimate of full-year 2019 return on year-end equity in the Idaho jurisdiction (Idaho ROE),ROE, in the first halfnine months of 2019 Idaho Power recorded no additional accumulated deferred investment tax credits (ADITC)ADITC amortization or provision against current revenues for sharing of earnings with customers for 2019 under the Idaho regulatory settlement stipulation approved in October 2014. Idaho Power recorded a $1.5 million provision against revenues for sharing of earnings with customers during the first nine months of 2018, based on its estimate of full-year 2018 Idaho ROE.

During the first nine months of 2018, Idaho Power recorded tax benefits for a $5.7 million remeasurement of deferred taxes resulting from income tax reform and the $1.3 million tax deduction for bond redemption costs incurred in the first nine months of 2018. There was no such remeasurement or bond redemption in the same period of 2019. Also, the first nine months of 2018 included a benefit from plant-related income tax return adjustments, which are generally recorded during the third quarter each year upon completion of the prior year tax return, which reduced Idaho Power income tax expense in the first nine months of 2018. These items, combined with lower excess deferred income tax reversal amounts, resulted in higher income tax expense in the first nine months of 2019 compared with the same period of 2018.

Overview of General Factors and Trends Affecting Results of Operations and Financial Condition

IDACORP's and Idaho Power's results of operations and financial condition are affected by a number of factors, and the impact of those factors is discussed in more detail below in this MD&A. To provide context for the discussion elsewhere in this report, some of the more notable factors are summarized below:

Table of Contents

Regulation of Rates and Cost Recovery: The prices 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. Idaho Power focuses on timely recovery of its costs through filings with its regulators, working to put in place innovative regulatory mechanisms, and on the prudent management of expenses and investments. Idaho Power has regulatory settlement stipulations in Idaho that include provisions for the accelerated amortization of certain tax credits to help achieve a minimum 9.5 percent (9.4 percent after 2019) Idaho ROE. The settlement stipulations also provide for the potential sharing between Idaho Power and its Idaho customers of Idaho-jurisdictional earnings in excess of 10.0 percent of Idaho ROE. The settlement stipulations provide for modification of certain terms and the indefinite extension of the mechanism beyond the original termination date of December 31, 2019. The specific terms of these settlement stipulations are described in Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2018 Annual Report. During 2019, Idaho Power will continue to assess the need to file a general rate case to reset base rates but does not anticipate filing a rate case in the next twelve months.

Economic Conditions and Loads: Economic conditions impact consumer demand for energy, revenues, collectability of accounts, the volume of wholesale energy 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. Over the 12twelve months ended JuneSeptember 30, 2019, Idaho Power's customer count grew by 2.52.6 percent. Idaho Power expects its number of customers to continue to increase in the foreseeable future. Employment in Idaho Power's service area grew by approximately 2.73.3 percent during the twelve months ended June 30, 2019, based on Idaho Department of Labor preliminary June 2019 data. 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.

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, which is described in Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report.

Further, as Idaho Power's hydropower facilities comprise nearly one-half of Idaho Power's nameplate generation capacity, precipitation levels impact the mix of Idaho Power's generation resources. When hydropower generation is reduced, Idaho Power must rely on more expensive generation sources and purchased power. When favorable hydropower generating conditions exist for Idaho Power, they also may exist for other Pacific Northwest hydropower facility operators, lowering regional wholesale market prices and impacting the revenue Idaho Power receives from wholesale energy sales. Much of the adverse or favorable impact of this volatility is addressed through the Idaho and Oregon power cost adjustment mechanisms. For 2019, Idaho Power expects generation from its hydropower resources to be in the range of 8.0 to 9.08.5 million MWh, compared with 20-year average annual hydropower generation of 7.5 million MWh.

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 and certain other assets, 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 in an effort to maintain system reliability, to ensure an adequate supply of electricity, and to provide service to new customers, including major ongoing transmission projects such as the Boardman-to-Hemingway and Gateway West projects. Idaho Power's existing hydropower and thermal generation facilities also require continuing upgrades and equipment replacement, and the company is undertaking a significant relicensing effort for the Hells Canyon Complex (HCC), its largest hydropower generation resource. Idaho Power intends to pursue inclusion of significant completed capital projects into rate base as part of a general rate case or other appropriate regulatory proceeding.

Mitigation of Impact of Fuel and Purchased Power Expense: In addition to hydropower generation, Idaho Power relies significantly on natural gas and coal to fuel its generation facilities and on power purchases in the wholesale markets. Fuel costs are impacted by electricity sales volumes, the terms and conditions of contracts for fuel, Idaho Power's generation capacity, the availability of hydropower generation resources, transmission capacity, energy market prices, and Idaho Power's hedging program for managing fuel costs. Purchased power costs are impacted by the terms and conditions of contracts for purchased power, the rate of expansion of alternative energy generation sources such as wind or solar energy, and wholesale energy market prices. The Idaho and Oregon power cost adjustment mechanisms mitigate in large part the potential adverse impacts to Idaho Power of fluctuations in power supply costs.

Regulatory and Environmental Compliance Costs: Idaho Power is subject to extensive federal and state laws, policies, and regulations, as well as regulatory actions and audits by agencies and quasi-governmental agencies, including the FERC, the North American Electric Reliability Corporation, and the Western Electricity Coordinating Council. Compliance with these requirements directly influences Idaho Power's operating environment and affects Idaho Power's operating costs. Recently, energy industry regulators have issued substantial penalties for utilities alleged to have violated reliability and critical infrastructure protection requirements. Moreover, environmental laws and regulations, in particular, may increase the cost of constructing new facilities, may increase the cost of operating generation plants, including Idaho Power's jointly-owned coal-fired generating plants, may require that Idaho Power install additional pollution control devices at existing generating plants, or may require that Idaho Power cease operating certain generation plants. Idaho Power expects to spend significant amounts on environmental compliance and controls in the next decade, and due to economic factors in part associated with the costs of compliance with environmental regulation, has accelerated the retirement dates of two of its co-ownedjointly-owned coal-fired powergenerating plants.
 
Water Management and Relicensing of the Hells Canyon Hydropower 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 hydropower projects. Also, Idaho Power is involved in renewing its long-term federal license for the HCC, its largest hydropower generation source. Given the number of parties involved, Idaho Power's relicensing costs have been and are expected to continue to be substantial. Idaho Power cannot currently determine the ultimate terms of, and costs associated with, any resulting long-term license.

(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 cooling. 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.
(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 normal amounts are the sum of the monthly normal amounts. These normal amounts are computed by the National Oceanic and Atmospheric Administration.

Sales Volume and Generation: Retail sales volumes decreased 5 percent and 1 percent in both the secondthird quarter and first sixnine months of 2019, respectively, compared with the same periods of 2018. DuringGreater precipitation in Idaho Power's service area during the second quarter ofthree and nine months ended September 30, 2019, decreased usage per irrigation customer wascustomers by approximately 206 percent lowerand 12 percent, respectively, compared with the same periodperiods in 2018. Precipitation in the Idaho Power service area increased significantly during the three months ended June 30, 2019, compared with the same period of 2018, which decreased usage by irrigation customers. During the secondthird quarter of 2019, usage per residential customer wasand usage per commercial customer were each approximately 32 percent lower than the same period of 2018, primarily due to coolermore moderate temperatures, during the second quarter of 2019, which decreased the use of electricity for coolingair conditioning purposes. Cooling degree-days in Boise, Idaho, were 17 percent lower during the three months ended June 30, 2019, compared with the three months ended June 30, 2018, and 13 percent below normal. Customer growth partially offset the decrease in sales volumes per customer during the three and sixnine months ended JuneSeptember 30, 2019, compared with the same periods in 2018, with the number of Idaho Power's customers growing by 2.52.6 percent over the prior twelve months.

Total system generation decreased 2 percent for the third quarter compared with the third quarter in 2018. During the third quarter of 2019, hydropower generation increased 2 percent, purchased power increased 6 percent, and thermal generation decreased 6 percent compared with the third quarter in 2018. Total system generation increased 3 percent during the first nine months of 2019 as a 5 percent decrease in hydropower generation and 6 percent respectively, during the second quarter and first six months of 2019decrease in purchased power led to a 23 percent increase in thermal generation compared with the same periodsperiod in 2018. In the second quarter and first six months of 2019, higher regional energy market prices resulted in a 15 percent and 13 percent decrease, respectively, in purchased power volumes compared with the same periods of 2018 as Idaho Power used its own generation resources to meet customer demand.

The financial impacts of fluctuations in wholesale energy 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.

(1) The FCA mechanism is an alternative revenue program and does not represent revenue from contracts with customers.
(2) As part of its January 30, 2009, general rate case order, the IPUC is allowing Idaho Power to recover a portion of the allowance for funds used during construction (AFUDC) on construction work in progress related to the HCC relicensing process, even though the relicensing process is not yet complete and the costs have not been moved to electric plant in service. Idaho Power is collecting approximately $8.8 million annually in the Idaho jurisdiction but is deferring revenue recognition of the amounts collected until the license is issued and the accumulated license costs approved for recovery are placed in service.

Changes in rates, changes in customer demand, and changes in FCA mechanism revenues are the primary reasons for fluctuations in retail revenues from period to period. The primary influences on 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. Rates are also seasonally adjusted, providing for higher rates during peak load periods, and residential customer rates are tiered, providing for higher rates based on higher levels of usage. The seasonal and tiered rate structures contribute to seasonal fluctuations in revenues and earnings.

Retail revenues decreased $30.2$17.2 million during the secondthird quarter of 2019, and decreased $27.0$44.2 million during the first sixnine months of 2019, compared with the same periods in 2018. The factors affecting retail revenues during the period are discussed below.

Rates: Customer rates, excluding collections of amounts related to the power cost adjustment mechanism, decreased revenues by approximately $9$0.8 million and $6$6.7 million for the three and sixnine months ended JuneSeptember 30, 2019, respectively, compared with the same periods in 2018. The settlement stipulations approved by the IPUC and OPUC during the second quarter of 2018 relating to income tax reform reduced revenues in the secondthird quarter and first sixnine months of 2019 more significantly than in the same periods of 2018. To a lesser extent, changes inCustomer rates also include the customer sales mix decreased average rates as volumes soldreturn to residential customers made up a lesser portion of the customer sales mix in the second quarter of 2019 compared with the second quarter of 2018. Residential, commercial, and irrigation customers generally pay a higher per-MWh rate than industrial customers.
Customer rates also include the return to

customers of amounts related to the power cost adjustment mechanism, which decreased revenues by $9.4$14.6 million and $17.1$31.7 million in the secondthird quarter and first sixnine months of 2019, respectively, compared with the same periods of 2018. The amount returned to customers in rates under the power cost adjustment mechanism has no effect on operating income as a corresponding amount is recorded as a reduction of expense in the same period it is returned through rates. Also, during the second quarter and first six months of 2019, residential and commercial customers used less energy per customer for cooling purposes, primarily due to cooler temperatures compared with the same periods of 2018.
Customers: Customer growth of 2.52.6 percent increased retail revenues by $5.6$8.0 million and $11.7$20.2 million in the secondthird quarter and first sixnine months of 2019, respectively, compared with the same periods of 2018.
Usage: Decreased usage (on a per customer basis), primarily by irrigation customers, decreased retail revenues by $19.6$13.0 million and $15.3$28.7 million for the secondthird quarter and first sixnine months of 2019, respectively, compared with the same periods of 2018. Decreased usage by irrigation customers was primarily the result of highergreater precipitation in Idaho Power's service area during the secondthird quarter and first sixnine months of 2019 compared with the same periods of 2018. Also, residential and commercial customers used less energy per customer for air conditioning purposes, primarily due to more moderate temperatures compared with second and third quarters of 2018. The lower sales volumes on a per-customer basis in the second and third quarters of 2019 were partially offset by a 3 percent increase in sales volumes per residential customer in the first quarter of 2019 compared with the first quarter of 2018, as colder temperatures led residential customers to use more energy for heating.
Idaho FCA Revenue: The FCA mechanism, applicable to Idaho residential and small commercial customers, adjusts revenue each year to accrue, or defer, the difference between the authorized fixed-cost recovery amount per customer and the actual fixed costs per customer recovered by Idaho Power through volume-based rates during the year. Lower usage (on a per customer basis) by residential and small general service customers during the second quarter ofthree and nine months ended September 30, 2019, increased the amount of FCA revenue accrued by $1.8$1.7 million compared with the second quarter of 2018. Higher usage (on a per customer basis) by residential and small general service customers during the first six months of 2019 decreased the amount of FCA revenue accrued by $0.5$1.2 million, respectively, compared with the same period in 2018.
Sharing: Retail revenue was impacted in 2018 by Idaho Power's revenue sharing mechanism. This mechanism is associated with Idaho regulatory settlement agreements that provide 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. Idaho Power did not record any provision for sharing in third quarter and first nine months of 2019. During the third quarter and first nine months of 2018, Idaho Power recorded $1.5 million as a provision against current revenues.

Wholesale Energy Sales: Wholesale energy sales consist primarily of long-term sales contracts, opportunity sales of surplus system energy and sales into the energy imbalance market implemented in the western United States (Western EIM), and do not include derivative transactions. The table below presents Idaho Power’s wholesale energy sales for the three and sixnine months ended JuneSeptember 30, 2019 and 2018 (in thousands, except for per MWh amounts).

In the secondthird quarter of 2019, wholesale energy revenues decreased $7.1 million, or 57 percent, and the wholesale energy volume decreased 42 thousand MWh, or 22 percent, compared with the third quarter of 2018. Lower wholesale energy volume sold to the Western EIM was mainly due to the increased supply of wholesale gas in the market, which impacted the regional wholesale energy prices during the third quarter of 2019 compared with the third quarter of 2018. For the first sixnine months of 2019, wholesale energy revenues increased by $7.2$33.6 million, or 96 percent, and $40.7 million, respectively,the wholesale energy volume increased 179 thousand MWh, or 10 percent, compared with the same periodsfirst nine months of 2018. WholesaleThe third quarter decrease in wholesale energy sales volumesrevenues explained above was more than offset by the effect of increased 27 percent and 13 percent inregional wholesale energy prices during the second quarter and first six months of 2019 respectively, compared with the same periods of 2018. Below-normal2018, due primarily to below-normal temperatures in the Northwest, a decrease in energy imports due to equipment maintenance, constricted natural gas supply, and limited production from the federal hydroelectrichydropower system due to freezing temperatures and low water flow increased regional wholesale energy prices during the first quarter, and to a lesser extent, the second quarter of 2019, compared with the same periods of 2018. During the fourth quarter of 2018, a natural gas pipeline ruptured in British Columbia, Canada, disrupting natural gas flows to the Pacific Northwest and Western Canada, driving up wholesale energy and natural gas prices in the region. During the first quarter and the beginning of the second quarter of 2019, the pipeline was operating at reduced capacity, which also contributed to continued increased energy prices during the periods.

flow.

Transmission Wheeling-Related Revenues: Transmission wheeling-related revenues decreased $2.0$5.1 million or 14 percent,and $3.1 million during the secondthree and nine months ended September 30, 2019, respectively, compared with the same periods in 2018, largely due to lower hydropower generation by other utilities in the Pacific Northwest and more moderate summer temperatures throughout the region in the third quarter of 2019 compared with the secondthird quarter of 2018, primarily2018. During the first nine months of 2019, the third-
Table of Contents

quarter decrease described above was partially offset by higher wheeling volumes during the first quarter of 2019 due to a decrease inregional wholesale energy market activity. Also, Idaho Power's OATT rates that became effectivedecreased in October 2018. Transmission wheeling-related revenues increased $2.0 million, or 8 percent, in the first six months of 2019 compared with the same period of 2018, largely due to an increase in wheeling-related volumes during the first three months of 2019, partially offset by a decrease in Idaho Power's OATT rates that became effective in October 2018. Regional wholesale energy market activity increased wheeling-related volumes in the first quarter of 2019.

Energy Efficiency Program Revenues: In both Idaho and Oregon, energy efficiency riders fund energy efficiency program expenditures. Expenditures funded through the riders are reported as an operating expense with an equal amount recorded in 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. 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 JuneSeptember 30, 2019, Idaho Power's energy efficiency rider balances were a $1.6$3.3 million regulatory liability in the Idaho jurisdiction and a $1.2 million regulatory asset in the Oregon jurisdiction.

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 expenses 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 decreased $0.7$6.7 million, or 313 percent, in the second quarter of 2019, but increased $23.4 million, or 48 percent, in the first six months of 2019, compared with the same periods of 2018. The decrease in fuel expense in the secondthird quarter of 2019 compared with the secondthird quarter of 2018, was due to a 72 percent increase in hydroelectrichydropower generation, which reduced Idaho Power's utilization of gas and coal generation. The increase in fuelFuel expense increased $16.7 million, or 16 percent, in the first sixnine months of 2019 compared with the same periodfirst nine months of 2018 was due to a 23 percent increase in thermal generation volumes, which were 64 percent higher in 2019 compared with 2018, partially offset by the beneficial impact of natural gas hedges entered into during the first sixnine months of 2019. Increased thermal generation in the first sixnine months of 2019 offset an 8a 5 percent decrease in hydroelectrichydropower generation between the comparable periods and provided generation for economic sales of energy in the wholesale energy market. In the first sixnine months of 2019, gains on settled financial gas hedges of $12.4$11.6 million, entered into in accordance with Idaho Power's energy risk management policies, reduced natural gas fuel expense. Most of these realized hedging gains are providing a benefit to customers through the power cost adjustment mechanisms described below.

Power Cost Adjustment Mechanisms: Idaho Power's power supply costs (primarily purchased power and fuel expense, less wholesale energy 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 hydroelectrichydropower and thermal generation volumes and fuel costs, generation plant availability, and retail loads. To address the volatility of power supply costs, Idaho Power's power cost adjustment mechanisms in the Idaho and Oregon jurisdictions allow Idaho Power to recover from customers, or refund to customers, most of the fluctuations in power supply costs. In the Idaho jurisdiction, the PCA includes a cost or benefit sharing ratio that allocates the deviations in net power supply expenses between customers (95 percent) and Idaho Power (5 percent), with the exception of PURPA power purchases and demand response program incentives, which are allocated 100 percent to customers. The Idaho deferral period, or PCA year, runs from April 1 through March 31. Amounts deferred or accrued 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 represent the portion of the power supply cost fluctuations accrued under the power cost adjustment mechanisms. When actual power supply costs are lower than the amount forecasted in power cost adjustment rates, which was the case for all periods presented, most of the difference is accrued. When actual power supply costs are higher than the amount forecasted in power cost adjustment rates, most of the difference is deferred. The amortization of the prior year’s balances represents the offset to the amounts being collected or refunded in the current power cost adjustment year that were deferred or accrued in the prior power cost adjustment year (the true-up component of the power cost adjustment mechanism).

Other O&M Expenses: Other O&M expenses decreased $5.3$4.4 million, or 65 percent, and $2.6$7.0 million, or 13 percent, in the secondthird quarter and first sixnine months of 2019 compared with the same periods of 2018. OtherThe lower other O&M expenses relatedwere due in part to Idaho Power's hydropower generation decreased $1.1a decrease in labor and benefit costs of $1.6 million and $2.3$1.9 million forin the secondthird quarter and first sixnine months of 2019, respectively, compared with the same periods in 2018, due primarily to more costly maintenance projects at hydropower locations in the first half of 2018. For the second quarter of 2019, labor and benefit costs decreased $1.5 million compared with the second quarter of 2018, primarily related to the levels of accruals for variable employee-related costs. AsAdditionally, as provided by the settlement stipulation approved by the IPUC in 2018 related to income tax reform, other O&M expenses in the secondthird quarter and first sixnine months of 2018 included $1.1$2.9 million and $4.0 million, respectively, of non-cash amortization expense of regulatory deferrals that would otherwise be a future liability of Idaho customers. Also, for the first nine months of 2019 other O&M expenses related to Idaho Power's

hydropower generation decreased $2.0 million compared with the first nine months of 2018, due primarily to fewer maintenance projects at hydropower locations.

Income Taxes

IDACORP's and Idaho Power's income tax expense increased $1.3$12.6 million and $1.5$12.4 million, respectively, for the sixnine months ended JuneSeptember 30, 2019, when compared with the same period in 2018, primarily due to the tax deduction for bond redemption costs incurred in the secondfirst nine months of 2018, the remeasurement of deferred taxes due to tax reform and a benefit from plant-related income tax return adjustments in the third quarter of 2018.2018, and lower excess deferred income tax reversal.

LIQUIDITY AND CAPITAL RESOURCES

Overview
 
Idaho Power has been pursuing 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 hydropower and thermal generation facilities also require continuing upgrades and component replacement. Idaho Power anticipates these substantial capital expenditures to continue, with expected total capital expenditures of approximately $1.5 billion over the five-year period from 2019 (including expenditures incurred to-date in 2019) through 2023.

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. Idaho Power periodically files for rate adjustments for recovery of operating costs and capital investments to provide the opportunity to align Idaho Power's earned returns with those allowed by regulators. Idaho Power uses operating and capital budgets to control operating costs and capital expenditures. During the first sixnine months of 2019, Idaho Power continued its efforts to optimize operations, control costs, and generate operating cash inflows to meet operating expenditures, contribute to capital expenditure requirements, and pay dividends to shareholders.

As of July 26,October 25, 2019, 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 U.S. Securities and Exchange Commission (SEC) on May 17, 2019, which may be used for the issuance of debt securities and common stock;
Table of Contents

Idaho Power's shelf registration statement filed with the SEC on May 17, 2019, which may be used for the issuance of first mortgage bonds and debt securities; $500 million remains available for issuance pursuant to state regulatory authority; and
IDACORP's and Idaho Power's commercial paper, which may be issued up to an amount equal to the available credit capacity under their respective credit facilities.

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 or first mortgage bonds, if the companies believe terms available in the capital markets are favorable and that issuances would be financially prudent.

Based on planned capital expenditures and other O&M expenses, the companies believe they will be able to meet capital and debt service requirements and fund corporate expenses during at least the next twelve months with a combination of existing cash, operating cash flows generated by Idaho Power's utility business, availability under existing credit facilities, and access to commercial paper and long-term debt markets.

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 JuneSeptember 30, 2019, IDACORP's and Idaho Power's capital structures, as calculated for purposes of applicable debt covenants, were as follows:
  IDACORP Idaho Power
Debt 43% 45%
Equity 57% 55%

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 operating cash inflows for the sixnine months ended JuneSeptember 30, 2019, were $166$287 million and $162$265 million, respectively, a decrease of $30$79 million for IDACORP and $29$54 million for Idaho Power, compared with the same period in 2018. With the exception of cash flows related to income taxes, IDACORP's operating cash flows are principally derived from the operating cash flow of Idaho Power. Significant items that affected the comparability of the companies' operating cash flows in the first sixnine months of 2019 compared with the same period in 2018 were as follows:

decreased net income;
changes in deferred taxes and in taxes accrued and receivable combined to increase cash flows by $4$13 million at IDACORP and decrease cash flows by $8$18 million at Idaho Power;
changes in regulatory assets and liabilities, mostly related to the relative amounts of costs deferred and collected under the Idaho FCAPCA mechanism and demand-side management program, decreased operating cash flows by $14$29 million;
Idaho Power made $15 million of benefit plan contributions during the first six months of 2019, while it made contributions of $25 million for the same period in 2018;
changes in working capital balances due primarily to timing, including fluctuations in accounts receivable, other current assets, and accounts payable, as follows:
timing of collections of accounts receivable balances decreased operating cash flows by $3$12 million for IDACORP and $4Idaho Power;
the changes in other current assets decreased operating cash flows by $9 million for IDACORP and Idaho Power, respectively;which was primarily due to an increase in fuel stock inventory as a result of the timing of purchases and consumption of coal at Idaho Power's jointly-owned coal-fired generating plants; and
timing of accounts payable payments decreased operating cash flows by $31$25 million and $17increased operating cash flows by $30 million for IDACORP and Idaho Power, respectively, of which $14$55 million of the difference between IDACORP and Idaho Power related to intercompany estimated income tax payments.

Investing Cash Flows
 
Investing activities consist primarily of capital expenditures related to new construction and improvements to Idaho Power’s generation, transmission, and distribution facilities. IDACORP’s and Idaho Power’s net investing cash outflows for the sixnine months ended JuneSeptember 30, 2019, were $126$193 million and $123$190 million, respectively. Investing cash outflows for 2019 and 2018 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.
Table of Contents


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 expenses allocated to IDACORP, through cash flows from operations, commercial paper markets, sales of common stock, and credit facilities. IDACORP's and Idaho Power's net financing cash outflows for the sixnine months ended JuneSeptember 30, 2019, were $68$101 million and $64$97 million, respectively. In the first sixnine months of 2019, IDACORP and Idaho Power paid cash dividends of $64$96 million.

Financing Programs and Available Liquidity

IDACORP Equity Programs: In recent years, IDACORP has entered into sales agency agreements under which it could offer and sell shares of its common stock from time to time through a third-party agent. The most recent sales agency agreement terminated in May 2016. IDACORP has no current plans to issue equity securities other than under its equity compensation plans during 2019, and as of the date of this report, IDACORP has not pursued the execution of a new sales agency agreement.

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 2019, Idaho Power received orders from the IPUC, OPUC, and WPSC authorizing the company to issue and sell from time to time of 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
Table of Contents

IPUC is effective through May 31, 2022, 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.

In May 2019, Idaho Power filed a shelf registration statement with the SEC, which became effective upon filing, for the offer and sale of an unspecified principal amount of its first mortgage bonds. The issuance of first mortgage bonds requires that Idaho Power meet interest coverage and security provisions set forth in Idaho Power's Indenture of Mortgage and Deed of Trust, dated as of October 1, 1937, as amended and supplemented from time to time (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 additional first mortgage bonds Idaho Power could issue as of JuneSeptember 30, 2019 was limited to approximately $669 million. 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 JuneSeptember 30, 2019, Idaho Power could issue approximately $1.9$2.0 billion of additional first mortgage bonds based on retired first mortgage bonds and total unfunded property additions.

Pollution Control Tax-Exempt Bonds: In August 2019, Idaho Power purchased and remarketed two of its outstanding series of pollution control tax-exempt bonds, one in the aggregate principal amount of $49.8 million issued in 2003 by Humboldt County, Nevada and due in 2024, and the other in the aggregate principal amount of $116.3 million issued in 2006 by Sweetwater County, Wyoming and due in 2026. The bonds were remarketed with substantially the same terms, but with lower term interest rates. The term interest rate of the series due in 2024 decreased from 5.15 percent to 1.45 percent and the term interest rate of the series due in 2026 decreased from 5.25 percent to 1.70 percent. Idaho Power expects the lower interest rates to reduce interest expense by approximately $5.6 million annually for the next five years and $3.9 million annually thereafter for the final two years of the longer-lived bonds.

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, replacing prior credit agreements. 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 one time and letters of credit not to exceed $50 million at any one 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 one time outstanding. Idaho Power's facility may be increased, subject to specified conditions, to $450 million. The credit facilities currently provide for a maturity date of November 4, 2022. Other terms and conditions of the credit facilities are described in the 2018 Annual Report, in Part II, Item 7 - "MD&A - Liquidity and Capital Resources."

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
Table of Contents

its subsidiaries, and the aggregate value of outstanding hybrid securities. At JuneSeptember 30, 2019, the leverage ratios for IDACORP and Idaho Power were 43 percent and 45 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 JuneSeptember 30, 2019, IDACORP and Idaho Power believed 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 2019.

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,IPUC, the OPUC, and Wyomingthe WPSC for the issuance of short-term borrowings through November 2022. In anticipation of Idaho Power and
Table of Contents

IDACORP potentially seeking to extend the terms of their credit facilities, in October 2019 Idaho Power filed applications with the IPUC, the OPUC, and the WPSC seeking new authorizations to extend through December 31, 2026, short-term and mid-term borrowings for a term of three years or less by Idaho Power at any one time outstanding not to exceed $450 million.

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.

At July 26,October 25, 2019, IDACORP had no loans outstanding under its credit facilities and had no commercial paper outstanding. Idaho Power had no loans outstanding under its credit facilities and no commercial paper outstanding. During the three and sixnine months ended JuneSeptember 30, 2019, IDACORP and Idaho Power borrowed no short-term commercial paper.
 
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, depend in part on their respective credit ratings. There have been no changes to IDACORP's or Idaho Power's ratings or ratings outlook by Standard & Poor’s Ratings Services or Moody’s Investors Service from those included in the 2018 Annual Report. However, 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.  
 
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 JuneSeptember 30, 2019, Idaho Power had posted $1.8$1.5 million performance assurance collateral related to these contracts. 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 JuneSeptember 30, 2019, the amount of additional collateral that could be requested upon a downgrade to below investment grade is approximately $5.4$10.8 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 $125$191 million during the sixnine months ended JuneSeptember 30, 2019. The cash expenditure amount excludes net costs of removing assets from service. The table below presents Idaho Power's estimated accrual-basis expenditures for construction for 2019 (including amounts incurred to-date) through 2023 (in millions of dollars). The amounts in the table exclude AFUDC but include net costs of removing assets from service that Idaho Power expects would be eligible to include in rate base in future rate case proceedings. 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.

Major Infrastructure Projects: Idaho Power is engaged in the development of a number of significant projects and has entered into arrangements with third parties concerning joint infrastructure development. The discussion below provides a summary of developments in certain of those projects since the discussion of these matters included in Part II, Item 7 - "MD&A - Capital Requirements" in the 2018 Annual Report. The discussion below should be read in conjunction with that report.

Boardman-to-Hemingway Transmission Line: The Boardman-to-Hemingway line, a proposed 300-mile, 500-kV transmission project between a station near Boardman, Oregon, and the Hemingway station near Boise, Idaho, would provide transmission service to meet future resource needs. In January 2012, Idaho Power entered into a joint funding agreement with PacifiCorp and the Bonneville Power Administration to pursue permitting of the project. The joint funding agreement provides that Idaho Power's interest in the permitting phase of the project would be approximately 21 percent, and that during future negotiations relating to construction of the transmission line, Idaho Power would seek to retain at least that percentage interest in the completed project. Total cost estimates for the project are between $1.0 billion and $1.2 billion, including Idaho Power's AFUDC. This cost estimate is preliminary and excludes the impacts of inflation and price changes of materials and labor resources that may occur following the date of the estimate.

Approximately $103$104 million, including AFUDC, has been expended on the Boardman-to-Hemingway project through JuneSeptember 30, 2019. Pursuant to the terms of the joint funding arrangements, Idaho Power has received $71 million as of JuneSeptember 30, 2019, from project co-participants for their share of costs. As of the date of this report, no material co-participant reimbursements are outstanding. Joint permitting participants are obligated to reimburse Idaho Power for their share of any future project permitting expenditures incurred by Idaho Power.

The permitting phase of the Boardman-to-Hemingway project is subject to federal review and approval by the U.S. Bureau of Land Management (BLM), the U.S. Forest Service, the Department of the Navy, and certain other federal agencies. The BLM issued its record of decision for the project in November 2017, approving a right-of-way grant for the project to cross approximately 86 miles of BLM-administered land. The U.S. Forest Service issued its record of decision in November 2018 authorizing the project to cross approximately 7seven miles of National Forest lands. Idaho Power also expectsIn September 2019, the Department of the Navy to issueissued its record of decision on whether to approveauthorizing the project to cross approximately 7seven miles of Department of the Navy lands in 2019.lands. In the separate Oregon state permitting process, in May 2019, the Oregon Department of Energy issued a Draft Proposed Order in May 2019 that recommends approval of the project to the state's Energy Facility Siting Council. The Oregon Department of Energy is expected to issue a Proposed Order in late 2019 or early 2020. Given the status of ongoing permitting activities and the construction period, Idaho Power expects the in-service date for the transmission line to be in 2026 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 located near Boise, Idaho. In January 2012, Idaho Power and PacifiCorp entered a joint funding agreement for permitting of the project. Idaho Power has expended approximately $40 million, including Idaho Power's AFUDC, for its share of the permitting phase of the project through JuneSeptember 30, 2019. 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 $250 million and $450 million, including AFUDC. Idaho Power and PacifiCorp continue to coordinate the timing of next steps to best meet customer and system needs.

Defined Benefit Pension Plan Contributions

Idaho Power has no minimum contribution requirement to its defined benefit pension plan in 2019; however, after evaluating market conditions and expected 2019 cash flows, Idaho Power contributed $10$40 million to the plan during the first sixnine months of

with the amount and timing of contributions and to mitigate the cost of being in an underfunded position. The primary impact of pension contributions is on the timing of cash flows, as the timing of cost recovery lags behind contributions.

Contractual Obligations
 
During the sixnine months ended JuneSeptember 30, 2019, IDACORP's and Idaho Power's contractual obligations, outside the ordinary course of business, did not change materially from the amounts disclosed in the 2018 Annual Report, except that Idaho Power entered into four new replacement contracts for expiring power purchase agreements with hydropower PURPA-qualifying facilities and one new agreement with a solar PURPA-qualifying facility, which increased Idaho Power's contractual purchase obligations by approximately $24 million over the 20-year terms of the contracts.

Also, in March 2019, Idaho Power signed a 20-year power purchase agreement, subject to final regulatorypending approval by the IPUC and OPUC, to purchase the output from a 120 MWplanned 120-megawatt solar facility proposed to be constructed by a third party. Thefacility. If approved, the agreement would increase contractual obligations by $136 million over the 20-year term. In October 2019, Idaho Power exercised its right under the power purchase agreement to negotiate during the fourth quarter of this year for the acquisition by Idaho Power or its affiliates of the right to own the planned 120-megawatt solar facility. If an acquisition agreement is reached and the power purchase agreement is approved by the IPUC and OPUC, it could affect the net impact on Idaho Power or its affiliates of the contractual obligation related to the 20-year power purchase agreement described above.

Off-Balance Sheet Arrangements

IDACORP's and Idaho Power's off-balance sheet arrangements have not changed materially from those reported in MD&A in the 2018 Annual Report.

REGULATORY MATTERS
 
Introduction

Idaho Power's development of regulatory filings takes into consideration short-term and long-term needs for rate relief and involves several factors that can affect the timing of these filings. These factors include, among others, the in-service dates of major capital investments, the timing and magnitude 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 filed2011. In 2012, large single-issue rate cases 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.Oregon. 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. The IPUC and OPUC have also approved smaller base rate changes in single issue cases subsequent to 2014. Between general rate cases, Idaho Power relies upon customer growth, a fixed cost adjustment mechanism, power cost adjustment mechanisms, tariff riders, and other mechanisms to mitigate the impact of regulatory lag, which refers to the period of time between making an investment or incurring an expense and recovering that investment or expense and earning a return. Management's regulatory focus in recent years has been largely on regulatory settlement stipulations and the design of rate mechanisms. Idaho Power continues to assess the need and timing of filing a general rate case in its two retail jurisdictions, based on its consideration of factors such as those described above, but does not anticipate filing a general rate case in the next twelve months.

The outcomes of significant proceedings are described in part in this report and further in the 2018 Annual Report. In addition to the discussion below, which includes notable regulatory developments since the discussion of these matters in the 2018 Annual Report, refer to Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report for additional information relating to Idaho Power's regulatory matters and recent regulatory filings and orders.

Notable Rate Changes During 2019

During 2019, Idaho Power received orders authorizing the rate changes summarized in the table below.
Description Status 
Estimated Rate Impact(1)
 Notes
Power Cost Adjustment Mechanism - Idaho New PCA rate became effective June 1, 2019 $50.1 million PCA decrease for the period from June 1, 2019 to May 31, 2020 The potential revenue impact of rate increases and decreases associated with the Idaho PCA mechanism is largely offset by associated increases and decreases in actual power supply costs and amortization of deferred power supply costs. The decrease includes a $5.0 million credit to customers for sharing of 2018 earnings under the IPUC order approving the extension, with modifications, of the terms of the December 2011 Idaho settlement stipulation for the period from 2015 through 2019 (October 2014 Idaho Earnings Support and Sharing Settlement Stipulation) and a $2.7 million credit for income tax reform benefits related to Idaho Power's OATT rate under a May 2018 Idaho tax reform settlement stipulation as described below in this MD&A.
Fixed Cost Adjustment Mechanism - Idaho New FCA rate became effective June 1, 2019 $19.2 million FCA increase for the period from June 1, 2019 to May 31, 2020 The FCA is designed to remove a portion of Idaho Power’s financial disincentive to invest in energy efficiency programs by partially separating (or decoupling) the recovery of fixed costs from the volumetric kilowatt-hour charge and instead linking it to a set amount per customer.
Valmy Plant Agreement - Idaho New base rate became effective June 1, 2019 $1.2 million annual increase In February 2019, Idaho Power reached an agreement with NV Energy that facilitates the planned end of Idaho Power's participation in coal-fired operations at units 1 and 2 of its jointly-owned North Valmy coal-fired power plant (Valmy Plant)Plant in 2019 and 2025, respectively. In May 2019, the IPUC issued an order approving the Valmy Plant agreement and allowing Idaho Power to recover through customer rates in Idaho the $1.2 million incremental annual levelized revenue requirement associated with required Valmy Plant investments and other exit costs.
Valmy Plant Agreement - OregonNew base rate effective January 1, 2020$3.2 million annual decreaseIn February 2019, Idaho Power reached an agreement with NV Energy that facilitates the planned end of Idaho Power's participation in coal-fired operations at units 1 and 2 of its Valmy Plant in 2019 and 2025, respectively. In October 2019, the OPUC approved the Valmy Plant agreement and authorized Idaho Power to adjust customer rates in Oregon, effective January 1, 2020, to reflect a decrease in the annual levelized revenue requirement of $3.2 million, which mostly relates to the associated decrease in depreciation expense and other costs. Idaho Power expects the effect on net income to be immaterial.
(1) The annual amount collected in rates is typically not recovered on a straight-line basis (i.e., 1/12th per month), and is instead recovered in proportion to retail sales volumes.

Idaho Earnings Support and Sharing from Idaho Settlement Stipulation

In October 2014, the IPUC issued an order approving the October 2014 Idaho Earnings Support and Sharing Settlement Stipulation extending, with modifications, the terms of a December 2011 Idaho settlement stipulation for the period from 2015 through 2019. A May 2018 Idaho settlement stipulation related to tax reform (May 2018 Idaho Tax Reform Settlement Stipulation) provides for the extension of the October 2014 Idaho Earnings Support and Sharing Settlement Stipulation beyond the initial termination date of December 31, 2019, with modified terms related to the ADITC and revenue sharing mechanism to become effective beginning January 1, 2020. The more specific terms and conditions of the October 2014 Idaho Earnings Support and Sharing Settlement Stipulation and the May 2018 Idaho Tax Reform Settlement Stipulation are described in Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2018 Annual Report. IDACORP and Idaho Power believe that the terms allowing additional amortization of ADITC in the settlement stipulations provide the companies with a greater degree of earnings stability than would be possible without the terms of the stipulations in effect.

Based on its estimate of full-year 2019 Idaho ROE, in both the secondthird quarter and first sixnine months of 2019, Idaho Power recorded no additional ADITC amortization or provision against current revenues for sharing of earnings with customers for 2019 under the October 2014 Idaho Earnings Support and Sharing Settlement Stipulation. DuringAccordingly, at September 30, 2019, the second quarter of 2018, Idaho Power reversed the $0.5full $45 million of additional ADITC amortizationremains available for future use under the terms of the October 2014 Idaho Earnings Support and Sharing Settlement Stipulation. Idaho Power recorded a $1.5 million provision against revenues for sharing of earnings with customers during the firstthird quarter of 2018, as actual financial results exceededbased on its then-current estimate of full-year 2018 Idaho Power's early estimates.ROE.

Change in Deferred Net Power Supply Costs and the Power Cost Adjustment Mechanisms

Deferred (accrued) 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 (accrued) power supply costs are recorded on the balance sheets for future recovery or refund through customer rates.

The table that follows summarizes the change in deferred (accrued) net power supply costs during the sixnine months ended JuneSeptember 30, 2019 (in millions).

Idaho Power's power cost adjustment mechanisms in its Idaho and Oregon jurisdictions address the volatility of power supply costs and 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 condensed consolidated financial statements included in this report. With the exception of power supply expenses incurred under PURPA and certain demand response program costs that are passed through to customers substantially in full, the Idaho PCA mechanism allows Idaho Power to pass through to customers 95 percent of the differences in actual net power supply expenses as compared with base net power supply expenses, whether positive or negative. Thus, the primary financial statement impact of power supply cost deferrals or accruals is that the timing of when cash is paid out for power supply expenses differs from when those costs are recovered from customers, impacting operating cash flows from year to year.

Open Access Transmission Tariff Draft Posting

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 MayAugust 2019, Idaho Power publicly postedfiled its 2019 draftfinal transmission rate with the FERC, reflecting a transmission rate of $27.32 per "kW-year," to be effective for the period from October 1, 2019, to September 30, 2020. A "kW-year" is a unit of electrical capacity equivalent to 1 kilowatt of power used for 8,760 hours. Idaho Power's draft rate wasis based on a net annual transmission revenue requirement of $107.0 million. The existing OATT rate in effect from October 1, 2018, to September 30, 2019, is $31.26was $31.25 per kW-year based on a net annual transmission revenue requirement of $123.1 million. The decrease in the OATT rate is largely attributable to federal tax reform and increased short-term firm and non-firm transmission revenues in 2018, which serve as an offset to the transmission revenue requirement.

2019 Integrated Resource Plan

Idaho Power filed its most recent IRP with the IPUC and OPUC in June 2019. The 2019 IRP assumes a forecasted annual growth in average energy demand of 1.0 percent and a forecasted annual growth in peak-hour demand of 1.2 percent over the 20-year period. The 2019 IRP identified a preferred resource portfolio and action plan, which includes the completion of the Boardman-to-Hemingway transmission line by 2026, the end to Idaho Power's participation in coal-fired operations at the Valmy Plant units 1 and 2 in 2019 and 2025, respectively, and the early retirement ofend to Idaho Power's participation in coal-fired operations at two Jim Bridger plant units in 2022 and 2026, respectively, and the acquisition of two solar resources in 2022 and 2023, respectively. However, as noted in the 2019 IRP, there is considerable uncertainty surrounding the resource sufficiency estimates and project completion dates, including uncertainty around the timing and extent of third party development of renewable resources, fuel commodity prices, the actual completion date of the Boardman-to-Hemingway transmission project, and the economics and logistics of plant retirements. These uncertainties, as well as others, could result in changes to the desirability of the preferred portfolio and adjustments to the timing and nature of anticipated and actual actions.
The 2019 IRP was Idaho Power's first IRP to use a long-term capacity expansion modeling system to identify economic resource portfolios under a range of future system conditions. This model simulates the entire western interconnection system
Table of Contents

to find an optimized western-interconnection resource portfolio. Subsequent to filing the 2019 IRP, Idaho Power identified that the optimization method used by the modeling software did not also model an optimized Idaho Power-specific system. Idaho Power is conducting further analysis and simulations on resource optimization based on an Idaho Power-specific systemsystem. On October 28, 2019, Idaho Power requested additional time from the IPUC to analyze the 2019 IRP modeling and expects to supplement the currently filed 2019 IRP with additional information and modeling results byin the endfirst quarter of October 2019.2020. If Idaho Power identifies significant differences in the results associated with additional modeling, it could modify the preferred resource portfolio identified in the 2019 IRP, which could alter the anticipated timing and nature of plant additions and retirements.

Renewable and Other Energy Contracts

Idaho Power has contracts for the purchase of electricity produced by third-party owned generation facilities, most of which produce energy with the use of renewable generation sources such as wind, solar, biomass, small hydropower and geothermal. The majority of these contracts are entered into as mandatory purchases under PURPA. As of JuneSeptember 30, 2019, Idaho Power had contracts to purchase energy from 127 on-line PURPA projects. An additional three contracts are with on-line non-PURPA projects, including the Elkhorn Valley wind project with a 101-MW nameplate capacity.

The following table sets forth, as of JuneSeptember 30, 2019, the resource type and nameplate capacity of Idaho Power's signed agreements for power purchases from PURPA and non-PURPA generating facilities. These agreements have original contract terms ranging from one to 35 years.

The projects not yet on-line include one hydropower PURPA project and five solar PURPA projects that are scheduled to be on-line in 2019 and one solar PURPA project scheduled to be onlineon-line in 2022. The non-PURPA solar project, subject to approval of the purchase agreement by the IPUC, is scheduled to be on-line in 2022.

In September 2019, the FERC issued a Notice of Proposed Rulemaking that, if adopted, could affect how states determine PURPA project avoided cost rates for purchases of power generated from qualified facilities (QF), which facilities are eligible for QF status, whether and when certain QFs can enter into purchase agreements with utilities, and how parties can contest the eligibility of a generation facility seeking QF status. As of the date of this report, Idaho Power is unable to determine the impact of these potential changes on the company's future obligations for new PURPA power purchase contracts, as it would require further action by the state public utility commissions to implement many of the changes. 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 reduce the number of future PURPA generation projects, which could reduce purchased power costs for Idaho Power. Substantially all PURPA power purchase costs are recovered through base rates and Idaho Power's power cost adjustment mechanisms.

Customer-Owned Generation Filings

In July 2017, Idaho Power filed an application with the IPUC related to residential and small commercial customers who install their own on-site generation, seeking the creation of two new classes of customers, with no request to change pricing or compensation.compensation (Residential and Small General Service Customer Case). In May 2018, the IPUC issued an order authorizing the creation of the new customer classes. In that order, the IPUC also stated its intent to open an Idaho Power-specific docket to
Table of Contents

comprehensively study on-site generation and ordered Idaho Power to file a study with the IPUC exploring fixed-cost recovery prior to its next general rate case. In September 2018, the IPUC issued an order requiring further investigation to resolve eligibility issues for the new customer classes. In October 2018, Idaho Power filed petitions requesting that the IPUC open two new cases to study fixed-cost recovery, and the costs and benefits of and the proper rate design for on-site generation, respectively. In April 2019, Idaho Power filed an application with the IPUC requesting that the IPUC initiate a proceeding to explore modifications, for implementation by January 1, 2020, to the compensation structure and excess energy value applied to rates for large commercial, industrial, and irrigation customers who install their own on-site generation. In April 2019, the IPUC issued an order acknowledging Idaho Power's application and setting forth procedures for the case to be processed.

On October 11, 2019, Idaho Power filed a settlement stipulation with the IPUC regarding changes to the compensation structure for customer generation in the Residential and Small General Service Customer Case. If the IPUC approves the settlement stipulation, the new compensation rates would begin to go into effect on January 1, 2020, and Idaho Power would implement the new pricing structure over an eight-year period.

Relicensing of Hydropower Projects

In connection with Idaho Power's efforts to relicense the HCC, Idaho Power's largest hydropower complex and a major relicensing effort, as described in more detail in the 2018 Annual Report in Part II, Item 7 - "Regulatory Matters," Idaho Power filed water quality certification applications, required under Section 401 of the Clean Water Act (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. Idaho Power 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.

Table of Contents

In April 2019, the states of Idaho and Oregon, along with Idaho Power, reached a settlement pertaining to the CWA Section 401 certification that requires Idaho Power to increase the number of Chinook salmon it releases each year through expanded hatchery production. Additionally, Idaho Power is required to fund a total of $12 million of research and water quality improvements in the HCC, over a 20-year period following the issuance of the license. These measures are in exchange for Oregon removing the fish passage requirement from the Oregon Section 401 certification for at least the first 20 years after final license issuance. Idaho Power estimates that the combined cost of the mandated water quality improvements and expanded hatchery production is $20 million over the first 20 years of the new license term. In May 2019, Oregon and Idaho issued final CWA Section 401 certifications. These certifications have been submitted to the FERC as part of the relicensing process. In July 2019, several third-parties filed lawsuits against the Oregon Department of Environmental Quality in Oregon state court challenging the Oregon CWA Section 401 certification based on fish passage, water temperature, and mercury issues associated with the Snake River and HCC. No parties challenged the Idaho CWA 401 certification by the applicable deadline.certification. Idaho Power continues to expect the FERC to issue an HCC license no earlier than 2022.

Costs for the relicensing of Idaho Power's hydropower projects are recorded in construction work in progress until new multi-year licenses are issued by the FERC, at which time the charges are transferred to electric plant in service. Idaho Power expects to seek timely recovery of relicensing costs and costs related to a new long-term license through the ratemaking process. Relicensing costs of $311$318 million (including AFUDC) for the HCC were included in construction work in progress at JuneSeptember 30, 2019. As of the date of this report, the IPUC authorizes Idaho Power to include in its Idaho jurisdiction rates $8.8 million of AFUDC annually relating to the HCC relicensing project. Collecting these amounts currently will reduce future collections when HCC relicensing costs are approved for recovery in base rates. As of JuneSeptember 30, 2019, Idaho Power's regulatory liability for collection of AFUDC relating to the HCC was approximately $143$148 million.

When the FERC issues a new long-term license, Idaho Power will begin operating under the requirements contained in the new license. Idaho Power expects those requirements to increase both other O&M expenditures and capital expenditures. Because Idaho Power is uncertain when the FERC will issue a new license, it has not included the expected capital expenditure increases in the “Capital Requirements” section of “Liquidity and Capital Resources” of this MD&A. As Idaho and Oregon issued final Section 401 certifications in May 2019, Idaho Power is updating its capital expenditure forecasts and expects to begin including the estimated capital expenditure increases in its disclosures as it refines the estimates in future periods. Idaho Power is unable to predict the exact timing of issuance of a new license for the HCC, or the ultimate financial or operational requirements of a new license.

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 Affordable Clean Energy (ACE) rule and other Clean Air Act (CAA) requirements, the CWA, the Resource Conservation and Recovery Act, the Toxic Substances Control Act, the Comprehensive Environmental Response, Compensation and Liability Act, and the Endangered Species Act (ESA), among other laws. These laws are administered by a number ofvarious 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 jointly-owned coal-fired power plants and three wholly-owned natural gas-fired combustion turbine power plants are subject to many of these regulations. Idaho Power's 17 hydropower projects are also subject to a number ofnumerous water discharge standards and other environmental requirements.

Compliance with current and future environmental laws and regulations may:

increase the operating costs of generating plants;
increase the construction costs and lead time for new facilities;
require the modification of existing generation 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 may 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. Beyond increasing costs generally, these environmental laws and regulations could affect IDACORP's and Idaho Power's results of operations and financial condition if the costs associated with
Table of Contents

these environmental requirements and early plant retirements cannot be fully recovered in rates on a timely basis. Part I - "Business - Environmental Regulation and Costs" in the 2018 Annual Report, includes a summary of Idaho Power's expected capital and operating expenditures for environmental matters during the period from 2019 to 2021. Given the uncertainty of future environmental regulations, Idaho Power is unable to predict its environmental-related expenditures beyond that time, though they could be substantial.

A summary of notable environmental matters impacting, or expected to potentially impact, IDACORP and Idaho Power, is included in Part II, Item 7 - "MD&A - Environmental Issues" and "MD&A - Liquidity and Capital Resources - Capital Requirements - Environmental Regulation Costs" in the 2018 Annual Report. Developments in certain environmental matters relevant to Idaho Power are described below.

Endangered Species Act Matters

Species Listings and Critical Habitat Designations

The listing of a species of fish, wildlife, or plant 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 hydropower facilities. When a species is added to the federal list of threatened and endangered species, it may be 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 August 2019, the U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) issued a set of regulatory changes to some of the standards under which listings, delisting, and reclassifications, and critical habitat designations are made. 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 reduce the role of climate change models in listing decisions and the designation of critical habitat in areas where
Table of Contents

species are not present, which could reduce Idaho Power’s obligations for mitigation under the ESA related to various construction and relicensing projects.

The construction of generation, transmission, or distribution facilities and the relicensing of Idaho Power's hydropower projects can be federally authorized actions that fall under the ESA. There are 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 ESA-listed fish and other aquatic species located in waterways in which Idaho Power has hydropower 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 hydropower 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 hydropower dams, potentially causing Idaho Power to rely on more expensive sources for power generation or market purchases.

Clean Air Act Matters

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 plant and the Boardman coal-fired plant. 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 nitrogen oxide (NOx) control at Jim Bridger plant 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 plant unit 2 by 2021 and unit 1 by 2022, which was submitted in December 2017. In November 2010, PacifiCorp and the WDEQ signed a settlement agreement under which PacifiCorp agreed to the timing and nature of the controls. The settlement agreement was conditioned on the EPA ultimately approving those portions of the Wyoming regional haze SIP that are consistent with the terms of the settlement agreement. In January 2014, the EPA approved Wyoming's regional haze SIP as to the Jim Bridger plant, with the NOx control compliance dates set forth in the settlement agreement. Several interested parties have appealed the EPA's decisions on Wyoming's regional haze SIP on various grounds. Idaho Power has not appealed the EPA's decisions but has intervened in the proceedings to participate if and to the extent the Jim Bridger plant could be affected.

In February 2019, PacifiCorp submitted to the WDEQ an alternative regional haze compliance plan for the Jim Bridger plant that includes a reduced plant-wide monthly limit on emissions for NOx and SO2 and an annual total emissions cap of NOx and SO2 for units 1-4. If the compliance plan as proposed is approved by WDEQ and finalized, Idaho Power does not believe it would move forward with the installation of SCR equipment at units 1 and 2.

Clean Water Act Matters

Definition of “Waters of the United States” Under the CWA: In August 2015, the U.S. Environmental Protection Agency's (EPA) and U.S. Army Corps of Engineers' (USACE) final rule defining the phrase "waters of the United States" (WOTUS) under the CWA became effective (WOTUS Rule). Idaho Power believes that the 2015 rule potentially expanded federal jurisdiction under the CWA beyond traditional navigable waters, interstate waters, territorial seas, tributaries, and adjacent wetlands, to a number of other waters, including waters with a "significant nexus" to those traditional waters. The WOTUS Rule was widely challenged in both federal district and circuit courts. The WOTUS Rule does not currently apply in twenty-eight28 states, including Idaho, and litigation regarding the WOTUS Rule continues. In February 2019, the EPA and the U.S. Army Corps of EngineersUSACE published a revised definition of WOTUS, which would reduce the number of waters in Idaho Power's service area subject to the WOTUS Rule. In September 2019, the EPA and USACE issued the final rule to repeal the WOTUS Rule and are expected to publish a final replacement rule defining WOTUS by the end of 2019.

Idaho Power has analyzed the WOTUS Rule and expects that, even if the WOTUS Rule is reinstated in Idaho and should the revised definition take effect in Idaho, while it may cause Idaho Power to incur additional permitting, regulatory requirements, and other costs associated with the rule, the aggregate amount of increased costs is unlikely to have a material adverse effect on Idaho Power's operations or financial condition, in part due to the relatively arid climate of Idaho Power's service area. Similarly, because the CWA, as interpreted even prior to the WOTUS Rule, applies to most of Idaho Power's facilities,

including its hydropower plants, Idaho Power does not expect this proposal to have a material impact on Idaho Power's operations or financial condition.

Clean Power Plan Repealed; Affordable Clean Energy Rule Adopted: In June 2014, the EPA released, under Section 111(d) of the CAA, a proposed rule for addressing GHGgreenhouse gases (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. In August 2015, the EPA released the final rule under Section 111(d) of the CAA, referred to as the Clean Power Plan (CPP), which required states to adopt plans to collectively reduce 2005 levels of power sector CO2 emissions by 32 percent by the year 2030. OnIn June 19, 2019, the EPA released the ACE rule to replace the CPP under Section 111(d) of the CAA for existing electric utility generating units. The new rule provides states with new emissions guidelines that inform the state development of standards of performance to reduce CO2 emissions from existing generation facilities and is limited to reduction and compliance measures that occur at the physical location of each plant, removing the proposal to require reductions outside the boundaries of plants. The ACE rule also provides for more state-specific control over implementation of the rule to address greenhouse gas emissions from existing coal-fired power plants, with a focus on state evaluation of improvement potential, technical feasibility, applicability, and remaining useful life of each unit. States are required to submit their compliance plans to the EPA by July 2022. In August 2019, twenty-two states sued the EPA in federal appeals court to challenge the ACE rule.

Because the rule is premised on state implementation plans, the terms of which Idaho Power does not control, as of the date of this report Idaho Power is uncertain whether and to what extent the ACE rule may impact its operations in the near term. Idaho Power's preliminary review of the rule indicates that it may not have substantial impacts on Idaho Power's operation of existing thermal generation units due to its planned retirements and other planned upgrades at each generating facility.

OTHER MATTERS
 
Critical Accounting Policies and Estimates
 
IDACORP's and Idaho Power's discussion and analysis of their financial condition and results of operations are based upon their condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles. The preparation of these financial statements requires IDACORP and Idaho Power to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, IDACORP and Idaho Power evaluate these estimates, including those estimates related to rate regulation, retirement benefits, contingencies, asset impairment, income taxes, unbilled revenues, and bad debt. These estimates are based on historical experience and on other assumptions and factors that are believed to be reasonable under the circumstances, and are the basis for making judgments about the carrying values of assets and liabilities that are not readily

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
IDACORP is exposed to market risks, including changes in interest rates, changes in commodity prices, credit risk, and equity price risk. The following discussion summarizes material changes in these risks since December 31, 2018, 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 JuneSeptember 30, 2019. IDACORP has not entered into any of these market-risk-sensitive instruments for trading purposes.
 
Interest Rate Risk
 
IDACORP manages 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.
Table of Contents

 
Variable Rate Debt: As of JuneSeptember 30, 2019, IDACORP had no net floating rate debt, as the carrying value of short-term investments exceeded the carrying value of outstanding variable-rate debt.
 
Fixed Rate Debt: As of JuneSeptember 30, 2019, IDACORP had $1.8 billion in fixed rate debt, with a fair market value of approximately $2.0$2.1 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 $301$274 million if market interest rates were to decline by one percentage point from their JuneSeptember 30, 2019 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 changes in commodity prices 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. IDACORP's commodity price risk as of JuneSeptember 30, 2019, had not changed materially from that reported in Item 7A of IDACORP's Annual Report on Form 10-K for the year ended December 31, 2018 (2018 Annual Report). Information regarding Idaho Power’s use of derivative instruments to manage commodity price risk can be found in Note 1011 - "Derivative Financial Instruments" to the condensed consolidated financial statements included in this report.
 
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 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 JuneSeptember 30, 2019, Idaho Power had posted $1.8$1.5 million performance assurance collateral related to these contracts. Should Idaho Power experience a reduction in its credit rating on Idaho Power's unsecured debt to below investment grade Idaho Power could be subject to requests by its wholesale
Table of Contents

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 JuneSeptember 30, 2019, the amount of collateral that could be requested upon a downgrade to below investment grade was approximately $5.4$10.8 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.
 
IDACORP's credit risk related to uncollectible accounts, net of amounts reserved, as of JuneSeptember 30, 2019, had not changed materially from that reported in Item 7A of the 2018 Annual Report. Additional information regarding Idaho Power’s management of credit risk and credit contingent features can be found in Note 1011 - "Derivative Financial Instruments" to the condensed consolidated financial statements included in this report.

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 1210 - "Benefit Plans" to the consolidated financial statements included in the 2018 Annual Report.
