What does IDACORP do?
IDACORP, Inc. is a Boise-based utility holding company traded on the New York Stock Exchange as IDA. Its economic center is Idaho Power Company, a vertically integrated utility that generates, transmits, distributes, buys, and sells electricity. Regulated utility operations account for nearly all current business activity; smaller subsidiaries hold tax-credit investments and qualifying hydropower projects.
Where does the utility operate, and who are its customers?
Idaho Power served southern Idaho and eastern Oregon at year-end 2025, with franchises or rights to serve all or part of 25 Idaho counties and three Oregon counties. Residential accounts represented 560,606 customers, or roughly 84% of the total, but commercial, industrial, and irrigation users are economically important because they create different load shapes and weather sensitivities. The company's official company profile emphasizes low-cost hydropower, a fast-growing service territory, and more than a century of local utility operations.
| Business element | Official disclosure | Why it matters |
|---|---|---|
| Core subsidiary | Idaho Power Company | Utility regulation, rate-base investment, and customer demand drive the consolidated results. |
| Primary regulators | IPUC, OPUC, and FERC | Allowed rates, cost recovery, transmission rules, and hydropower licensing shape earnings and cash timing. |
| Customer concentration | Southern Idaho and eastern Oregon | Regional growth is an advantage, but weather, wildfire, water, and local economic conditions are concentrated. |
| Non-utility activities | Tax-credit investments and small hydro | They contribute tax and investment effects but do not change the utility-led nature of the company. |
How does IDACORP make money?
The model is primarily cost-of-service regulation. Idaho Power invests in generation, storage, transmission, distribution, and reliability; regulators determine prudent costs and set rates intended to recover expenses, depreciation, and an authorized return on invested capital. Results therefore depend on customer growth, rate cases, assets entering service, and mechanisms that match specified costs with future collections or refunds.
Which customer classes generate the most retail revenue?
Before the $15.1 million Hells Canyon relicensing deferral, FY2025 customer-class revenue totaled $1.571 billion. Residential customers contributed the largest share, followed by commercial, industrial, and irrigation accounts. Residential and commercial usage responds to weather, irrigation to precipitation, and industrial load to large-facility activity.
| Revenue stream | Pricing logic | Primary driver | Analytical implication |
|---|---|---|---|
| Retail electricity | Regulator-approved tariffs | Customers, rates, usage, and weather | Growth can be durable, but revenue and cash recovery may lag investment. |
| Wholesale energy | Market-based sales | Surplus generation and regional prices | Hydrology and market conditions affect volumes, although adjustment mechanisms reduce much of the earnings volatility. |
| Transmission | FERC-approved cost-based service | Regional grid use and capacity | Interconnections support reliability and create a smaller, infrastructure-linked revenue stream. |
| Tax-credit investments | Investment and tax benefits | Affordable-housing portfolio | Useful for tax planning, but economically secondary to Idaho Power. |
What does IDACORP's latest quarter show?
The quarter ended March 31, 2026 showed the central utility pattern: reported revenue fell, yet operating income and net income rose because power-cost accounting, approved rate changes, customer growth, and fixed-cost adjustment revenue changed the earnings mix. IDACORP's first-quarter release and the Form 10-Q provide the freshest reported evidence.
What moved earnings beneath the revenue line?
| Q1 2026 item | Reported amount | Year-over-year signal |
|---|---|---|
| Rate changes | +$18.0M operating-income effect | The January 1, 2026 Idaho base-rate increase was the largest positive operating driver. |
| Customer growth | +$5.0M operating-income effect | Approximately 15,000 additional customers, or 2.3% growth over twelve months. |
| Usage per customer | -$10.7M operating-income effect | Milder heating weather reduced residential and commercial usage. |
| Other O&M | -$13.1M operating-income effect | Wildfire mitigation and Jim Bridger conversion-cost amortization raised expense. |
| Operating cash flow | $75.8M | Down from $124.3M in Q1 2025, largely reflecting regulatory-asset and liability timing. |
| Property, plant, and equipment additions | $371.5M | Up from $201.3M in Q1 2025, showing the acceleration in construction spending. |
Why do regulated returns and customer growth define IDACORP?
Population and business expansion create load growth and the need for infrastructure, but financing precedes full rate recovery. The 2025 Idaho settlement authorized tariffs designed to increase annual Idaho-jurisdiction retail revenue by about $110.0 million, or 7.48%, effective January 1, 2026. It supported Q1 earnings, while regulatory lag, depreciation, and interest expense remained pressures.
How large is the current investment cycle?
Idaho Power spent $361 million of cash capital expenditures excluding allowance for funds used during construction in Q1 2026. Its forecast calls for $1.3-$1.5 billion in 2026, $1.4-$1.6 billion in 2027, and $3.6-$4.1 billion during 2028-2030. The five-year total is therefore $6.3-$7.2 billion, including more than $1.7 billion for resource additions. The 2025 Integrated Resource Plan announcement connects the spending to unprecedented demand growth, storage, generation, transmission, energy efficiency, and wildfire resilience.
What strategic turning points shaped IDACORP?
Today's business reflects long-lived assets, regulatory approvals, and gradual resource shifts. The timeline shows how a hydropower-centered regulated utility entered a storage- and transmission-heavy investment phase.
-
1916Idaho Power began operations. A century of local service, operating records, rights-of-way, and regulatory relationships forms the institutional base of the current franchise.
-
1998IDACORP was formed as the holding company. The structure separated the listed parent from Idaho Power while keeping the regulated utility as the dominant economic asset.
-
2011-2025The board increased the common dividend each year. The policy established income-investor relevance, but the present capital cycle has led management to decouple near-term dividend growth from EPS growth.
-
2019-2025Coal exposure declined through exits from North Valmy units, the Boardman plant, and conversion of two Jim Bridger units to natural gas. The shift lowers carbon intensity but creates conversion, replacement-resource, and recovery costs.
-
2023-2025Company-owned battery storage reached 307 MW, and a 150 MW contracted storage facility began service in May 2025. Storage became a core tool for meeting peak demand and integrating variable resources.
-
2025Construction began on the Boardman-to-Hemingway 500-kV transmission project after nearly 19 years of permitting. The project is designed to increase access to western energy markets and capacity.
-
2026A new Idaho rate settlement took effect, 250 MW of additional company-owned batteries were scheduled to enter service, and the capital structure required continuing debt and equity issuance.
The official company history and annual filings show continuity rather than abrupt reinvention: the moat remains the regulated network, while the investment agenda shifts with customer demand, reliability requirements, and resource economics.
What gives IDACORP a competitive advantage?
Idaho Power is a regulated monopoly in most of its territory, so its advantage is not a conventional consumer brand. It combines franchise rights, network assets, operating expertise, hydropower, customer relationships, and regional transmission access. A rival would need duplicate infrastructure, permits, rights-of-way, regulatory approval, and an obligation to provide reliable service.
Who actually competes with the business?
How durable is the moat?
Customer affordability is the weak point. Residential usage per customer declined from 1,032 kWh per month in 2012 to 922 kWh in 2025. Higher rates can encourage efficiency or self-generation, forcing a balance among reliability, investment, and bill pressure.
How financially strong is IDACORP?
The income statement is profitable and supported by regulated operations, but free cash flow is structurally negative during the current construction cycle because investment substantially exceeds operating cash generation. That is normal for a fast-growing regulated utility only if capital markets remain open and regulators allow timely recovery. The 2025 Annual Report provides the full-year baseline.
What do profitability, cash flow, and leverage say?
| Financial measure | FY2025 | FY2024 | Interpretation |
|---|---|---|---|
| Operating revenue | $1.813B | $1.827B | Lower power-cost collections can reduce revenue without implying weaker underlying earnings. |
| Operating income | $354.0M | $327.8M | The FY2025 operating margin was about 19.5%, up from about 17.9%. |
| Net income attributable to IDACORP | $323.5M | $289.2M | Earnings increased despite higher depreciation and financing costs. |
| Diluted EPS | $5.90 | $5.50 | Share issuance diluted some of the growth in absolute net income. |
| Operating cash flow | $602M | $595M | Cash generation was stable but below the investment requirement. |
| Cash capital expenditures | $1.1B | $981M | Simple free cash flow was materially negative because the company is building ahead of future rate recovery. |
| Long-term debt | $3.331B | $3.054B | Debt increased with the construction program; the effective debt cost was 5.13% at year-end 2025. |
How is capital being allocated?
| Use or source of capital | Current evidence | Investor meaning |
|---|---|---|
| Utility capital investment | $1.3-$1.5B 2026 guidance | The main reinvestment priority and future rate-base growth driver. |
| Debt financing | $350M issued in Q1 2026 | Supports projects but raises interest expense and rating sensitivity. |
| Equity financing | $52.9M common stock issued in Q1 2026; $155M forward sales arranged | Protects the balance sheet while diluting per-share growth. |
| Dividend | $0.88 quarterly; $3.52 indicated annual rate | The payout remains important, but near-term growth is constrained by financing needs. |
| Payout policy | 58.6% of FY2025 earnings | Within the adjusted near-term 50%-60% target, below the longer-term 60%-70% policy range. |
The board's September 2025 dividend increase explicitly acknowledged that elevated capital spending and EPS dilution require dividend growth to be managed separately from earnings growth.
Who owns IDACORP stock, and how is it governed?
IDACORP has one class of common stock, with one vote per share. Ownership is dispersed rather than founder-controlled, so large institutions, proxy voting policies, board independence, and access to public capital have more influence than any insider block. The 2026 Proxy Statement reported 55,408,235 voting shares outstanding at the March 31, 2026 record date.
Why does the ownership profile matter?
| Holder or governance group | Economic stake or structure | Source period | Why it matters |
|---|---|---|---|
| BlackRock | 5,973,856 shares; 10.9% | Proxy disclosure as of March 23, 2026 | A large passive institutional vote can influence director elections and governance practices. |
| Vanguard | 5,774,274 shares; 10.5% on proxy basis | Proxy disclosure with March 2026 reporting caveat | The economic exposure remains institutionally dispersed even as aggregate filing treatment changes. |
| Wellington Management | 3,424,956 shares; 6.2% | Proxy disclosure as of March 23, 2026 | Represents a significant actively managed institutional position. |
| Directors and executive officers | 183,885 shares; 0.33% | March 23, 2026 | Insider economics are aligned but do not create voting control. |
| Board composition | 10 nominees; nine independent and CEO Lisa Grow | 2026 annual meeting | Independent oversight is important for capital allocation, regulatory strategy, safety, and succession. |
Management must persuade regulators, customers, rating agencies, and institutional owners that construction can improve reliability and earnings without undermining affordability or balance-sheet quality.
Which KPIs matter most for IDACORP?
A conventional revenue-growth dashboard misses utility economics. The best KPIs connect demand, regulatory recovery, project delivery, and financing. Their relationships matter more than any single number.
| KPI | Recent reference point | How to interpret it |
|---|---|---|
| Customer growth | 2.3% over the twelve months ended March 31, 2026 | Supports load and rate-base demand, but may require investment before revenue recovery. |
| Retail usage | Q1 2026 retail volume down 3% year over year | Separates weather and efficiency effects from customer-count growth. |
| Hydropower generation | 5.5-7.0M MWh 2026 guidance | Lower water conditions can increase thermal generation or purchased-power requirements. |
| O&M expense | $525-$535M 2026 guidance | Shows whether wildfire, labor, conversion, and reliability spending are controlled and recoverable. |
| Capital expenditures | $1.3-$1.5B 2026 guidance | The foundation of future rate base, but also the source of debt, equity issuance, and negative free cash flow. |
| Debt / equity | 54% / 46% at March 31, 2026 | Measures financing pressure against the approximate 50/50 objective. |
| EPS and share count | $1.21 Q1 2026 EPS; 56.3M diluted weighted-average shares | Tests whether earnings growth is outpacing equity dilution. |
What should researchers monitor next?
What opportunities and risks could change IDACORP's outlook?
Growth and risk come from the same source: a rapidly expanding territory. More customers, industrial development, and electrification support a larger rate base, but also raise peak demand, accelerate construction, strain labor and equipment, and pressure bills and financing.
Which risks are most material?
The key question is whether IDACORP can preserve the compact among customers, regulators, and capital providers: reliable service and reasonable bills in exchange for timely recovery of prudent investment.
What is the key takeaway for valuation and research?
A DCF for IDACORP should begin with rate base, capital spending, allowed returns, regulatory lag, customer and load growth, cost recovery, depreciation, financing mix, and share issuance. During a construction-heavy period, conventional free cash flow is negative by design; value depends on today's investment becoming tomorrow's earning rate base above the cost of capital.
How should a student or investor frame the company?
For strategy work, IDACORP pairs high entry barriers with powerful regulators and customers who fund the system. For accounting work, regulatory assets, liabilities, AFUDC, and power-cost mechanisms explain why revenue and cash flow can diverge from earnings. For investment research, management must fund growth while preserving investment-grade credit and a sustainable dividend.
The clearest monitoring sequence is customer and load growth, project delivery, rate-case outcomes, operating cash flow, financing, diluted share count, EPS, and dividend coverage. It explains IDACORP better than a simple quarterly revenue comparison.
