Wyoming electric utility dumps wind and solar in long-term planning

PacifiCorp says it will add no new wind or solar facilities in Wyoming, Utah, Idaho or California from 2027 through 2045, citing the July 4, 2025 repeal of major IRA tax benefits under the One Big, Beautiful Bill Act. The utility says federal tax credits had reduced wind and solar project costs by about 30%, and the shift could make coal more competitive while lifting its emissions trajectory. The update signals weaker long-term demand for renewable development in Wyoming and could delay future projects across PacifiCorp’s six-state footprint.

Analysis

The near-term loser is not just renewable developers; it is the entire regional project-finance ecosystem that relied on a bankable utility offtaker to de-risk buildout. Once a regulated buyer signals a multi-decade pause, it raises the hurdle rate for merchant wind/solar, increases equity dilution risk for developers, and likely widens bid-ask spreads for transmission interconnect rights and late-stage permitting assets. The second-order beneficiary is dispatchable generation with existing interconnection, especially legacy thermal and hydro assets, because the option value of immediate capacity rises when new-build renewables lose their policy subsidy crutch.

For BRK.B, this is a subtle but real reputational and regulatory overhang rather than an immediate earnings hit. The market tends to underweight how integrated-resource-plan choices flow into future capex returns: slower renewable adoption can preserve near-term reliability optics, but it also increases the probability of higher long-run fuel and carbon compliance costs, which eventually lands back on rate base and political scrutiny. That creates a lagged risk that Wyoming and neighboring regulators revisit allowed returns if customers see rate relief fail to materialize despite the utility’s “cheaper power” narrative.

The consensus may be too linear in assuming policy rollback automatically resurrects coal economics. In practice, coal’s advantage is often temporary and local, while the structural cost curve for wind/solar continues to fall; the more important effect is a pause in utility-sponsored demand, not a secular death of the asset class. This makes the biggest opportunity a timing trade: the market may overshoot on near-term renewable pessimism, while longer-dated power shortages, load growth from data centers, and transmission constraints eventually force PacifiCorp and peers back into the market within 12-24 months.

Key Decisions for Investors

• Use BRK.B weakness as a tactical short-hedge target only on rallies, not a structural short: any underperformance should be sized as a 1-3 month relative-value trade versus XLU, with the thesis that regulatory and capex optics will pressure sentiment before fundamentals move.
• Go long independent renewable developers with diversified offtake and transmission optionality, not utility-tied names; favor 12-24 month horizons and prioritize businesses that can monetize merchant pricing or storage attachment rather than relying on regulated utility procurement.
• Consider a pair trade: long conventional utility/thermal exposure versus short pure-play wind/solar developers for the next 3-6 months, then begin covering into any broader selloff as project scarcity and data-center demand reassert themselves.
• Buy optionality on power-price upside through utilities or power indices where load growth is tight and supply is constrained; the key risk/reward is that delayed renewables can lift regional wholesale prices faster than regulators allow full pass-through, creating volatility in 6-18 months.
• Watch for a reversal catalyst in PacifiCorp’s next planning update or a large data-center PPA announcement; either would be the earliest signal that today’s pause is more tactical than permanent.
