Will Rising Customer Demand Boost IDACORP's Long-Term Growth?

IDACORP subsidiary Idaho Power added approximately 15,000 customers, while IDACORP’s second-quarter industrial revenues rose 17%; customer growth contributed $4.5 million to operating income under the stated exclusions. Idaho Power projects annual retail electricity sales growth of 8.3% and peak-demand growth of 5.1% over five years, and expects 2026 capital expenditures of $1.3–$1.5 billion within a planned $7.1 billion investment through 2030. Zacks consensus estimates call for EPS growth of 8.31% in 2026 and 8.42% in 2027; IDA shares rose 1.8% over the past month versus a 0.5% industry decline.

Analysis

IDACORP’s upside is not simply higher electricity sales: the equity value depends on how quickly incremental load becomes approved, earning rate base. The key transmission mechanism is regulatory recovery of generation and grid spending; construction delays, cost overruns, or slow rate cases could leave capital deployed before earnings catch up. Large-load contract protections mitigate stranded-asset risk, but do not eliminate concentration risk if a customer delays its ramp or changes plans. Verify executed agreements, customer credit, ramp schedules, and who pays for dedicated interconnection and upstream upgrades.

Near term (days to 1–3 months), the demand narrative may support relative sentiment, but the supplied information does not establish valuation or how much growth is priced in. Over 6–18 months, the decisive evidence is realized large-customer consumption, regulatory approval and recovery of planned investment, and financing costs—not pipeline announcements. A further risk is load arriving faster than dependable generation and transmission, potentially increasing procurement costs or reliability constraints.

The contrarian point: headline load growth is not synonymous with attractive returns. Customer-specific infrastructure can absorb capital while broader system upgrades create execution and affordability disputes. Conversely, if contracts allocate dedicated costs to customers and regulators allow timely recovery, the investment cycle could support durable earnings beyond the initial load ramp.

Key Decisions for Investors

• Treat IDA as a conditional, medium-term regulated-growth opportunity rather than buying solely on demand headlines. Reassess after filings or earnings disclose signed large-load commitments, ramp timing, customer-funded upgrades, and rate-base recovery.
• Consider a staged long IDA versus a diversified regulated-utility exposure only if relative valuation does not already price in superior growth; the article supplies no valuation basis for an unconditional pair trade. Keep the position small until contract and regulatory details are verified.
• Monitor realized large-load usage, capex execution, allowed returns and financing costs over the next 1–3 quarters. The thesis weakens if customer ramps slip, project costs rise without timely recovery, or management trims its demand outlook.
• Do not infer equivalent beneficiaries from the article’s customer names: higher power consumption may increase their operating costs, but the supplied information does not quantify any material earnings impact for Micron or Meta.
