IDAHO POWER CO Annual Report: What Investors Need to Know

Considering an investment in Idaho Power Co? This summary, based on their latest SEC 10-K filing, offers a clear look at their recent performance, future outlook, and key considerations. As a regulated electric utility, Idaho Power Co powers homes and businesses across Idaho and parts of Oregon. We break down its financial health, strategic initiatives, and risks in plain English to help you make an informed decision.

Business Overview

Idaho Power Co generates, transmits, and distributes electricity. The company manages all aspects of electricity delivery, owning and operating generation facilities (including hydroelectric, thermal, and combustion turbine plants), an extensive transmission network, and distribution infrastructure. Its primary service territory spans approximately 24,000 square miles in southern Idaho and eastern Oregon, serving over 630,000 customers. The Idaho Public Utilities Commission (IPUC) and the Oregon Public Utility Commission (OPUC) oversee its operations, rates, and services.

Financial Performance

For the fiscal year ended December 31, 2024 (with some events extending into early 2025), Idaho Power Co reported solid financial performance, driven by consistent revenue growth and effective regulatory management.

Revenue Growth: Idaho Power Co saw strong revenue growth. Total revenue for 2024 reached approximately $1.765 billion, a robust 7.1% increase from $1.648 billion in 2023. This continued a positive trend from $1.531 billion in 2022. Increased demand and successful rate adjustments fueled this growth.

Where the Money Came From (Retail Sales - 2024 vs. 2023):

• Residential customers: Revenue grew from $550 million in 2023 to $600 million in 2024 (up 9.1%).
• Commercial customers: Revenue increased from $420 million in 2023 to $450 million in 2024 (up 7.1%).
• Industrial customers: Revenue rose from $280 million in 2023 to $300 million in 2024 (up 7.1%).
• Irrigation customers: Revenue remained steady at $150 million in 2024, after growing from $130 million in 2022.

Other Income Streams (2024 vs. 2023):

• Wholesale energy sales: Increased from $90 million to $100 million.
• Transmission services (wheeling): Increased from $45 million to $50 million.
• Energy efficiency programs: Increased from $9 million to $10 million.

Risk Factors

• Regulatory Decisions: Outcomes of ongoing and future rate cases are critical. Unfavorable decisions on cost recovery or allowed profit margins could directly impact the company's profitability and financial health.
• Rising Interest Rates: While the company secured recent bond issuances, a continued rise in interest rates could make future borrowing more expensive, increasing financing costs and potentially hindering capital-intensive projects.
• Wildfire Costs & Recovery: Despite mitigation efforts, regulators may not allow full recovery of all wildfire-related expenses, or these costs could escalate beyond current projections, creating financial strain.
• Environmental Regulations: Stricter environmental rules could impose significant future costs, particularly for older generating plants like Valmy and Jim Bridger. These costs might include expensive upgrades, early retirements, or increased compliance expenses.
• Operational Risks: Beyond regulatory concerns, utilities face risks from severe weather, infrastructure failures, and cyberattacks, which can disrupt service and incur substantial costs.
• Economic Conditions: A regional economic downturn could reduce electricity demand and customers' ability to pay, affecting revenue.
• Hydrology and Weather: As a major owner of hydroelectric generation, the company's power supply and costs depend heavily on fluctuating water levels and weather patterns, which can significantly impact financial results.

Management Discussion and Analysis (MD&A) Highlights

Management reported a year of solid operational and financial performance, driven by effective regulatory engagement and strategic investments. Key achievements include consistent revenue growth across most customer segments, demonstrating the company's ability to meet growing demand. Securing regulatory approvals for cost recovery mechanisms, such as the Idaho Power Cost Adjustment (IPCA) and Fixed Cost Adjustment (FCA), is crucial for financial stability. These mechanisms allow the company to recover fluctuating power supply and fixed operating costs. Progress on the Hells Canyon Complex Relicensing represents a significant long-term win, securing vital low-cost generation assets.

However, management also acknowledges ongoing challenges. Wildfire mitigation costs are a substantial and increasing expenditure, and the company continues efforts to secure regulatory recovery. The continuous cycle of rate cases (e.g., the Idaho 2024 Limited Rate Case and the upcoming Idaho 2025 Rate Case) highlights the constant need to negotiate with regulators for adequate cost recovery and a fair return on investment. The company balances these challenges with ongoing capital investments to maintain reliability, modernize infrastructure, and integrate new technologies, all while navigating a complex regulatory landscape.

Financial Health

Debt Management: Idaho Power actively manages its long-term debt. In March 2025, it issued $250 million in First Mortgage Bonds at 5.70% interest due in 2055. This followed another $250 million issuance at 5.20% interest due in 2034 in August 2024. These issuances demonstrate its ability to access capital markets for long-term projects. It also successfully paid off a $10 million Pollution Control Bond in December 2024, reducing older obligations.

Regulatory Assets & Liabilities: For a regulated utility, regulatory assets and liabilities are crucial. Idaho Power holds "deferred costs" for items such as pension benefits, fuel, and wildfire mitigation. Crucially, a portion of these deferred costs are "earning a return." This means regulators allow the company to recover these costs, plus a profit, from customers over time, which supports financial stability. Understanding the size and recoverability of these assets and liabilities is vital for assessing future earnings.

Future Outlook

Idaho Power Co's future outlook hinges on its ongoing capital investment program, the regulatory environment, and its strategic focus on reliability and sustainability.

Strategic Focus & Future Outlook:

• Capital Investments: The company continuously invests in its infrastructure for reliability, modernization, and growth.
• Upcoming Rate Cases: The Idaho 2025 Rate Case, expected to influence 2026 finances, is a major near-term event that will shape future revenue and cost recovery. The company will continue to seek timely recovery of prudently incurred costs and a fair return on its investments.
• Plant Transitions: Mentions of the Valmy Plant and Boardman Plant in Oregon for 2026 suggest potential future developments. These could include retirements, fuel conversions, or significant upgrades, which may have substantial financial and operational implications as the company transitions its generation portfolio.
• Leadership Stability: Leadership appears stable.
• Customer Growth: The service territory continues to experience population and economic growth. This growth is expected to drive increased electricity demand and require ongoing infrastructure expansion.

Competitive Position

As a regulated electric utility, Idaho Power Co operates as a regulated monopoly within its defined service territory in Idaho and parts of Oregon. State regulatory bodies grant exclusive franchise rights, limiting direct competition for electricity delivery to most customers. Its competitive strength stems not from market share against other utilities, but from its ability to:

• Maintain strong relationships with regulators: This is essential for securing favorable rate case outcomes and cost recovery.
• Provide reliable and safe service: A fundamental customer expectation and key performance indicator.
• Manage costs effectively: This keeps rates competitive within the regulatory framework and ensures financial viability.
• Invest strategically in infrastructure: This meets growing demand, enhances grid resilience, and integrates new technologies.
• Access capital markets efficiently: This funds its capital-intensive operations and growth projects.

This comprehensive overview offers investors a clearer picture of Idaho Power Co's financial health, strategic direction, and the key factors influencing its performance.
