PacifiCorp's Washington Exit: A Utah Problem in Disguise?

PacifiCorp's proposed divestiture of its Washington operations has been framed primarily as a strategic retreat from a challenging regulatory environment. But a growing chorus of energy policy experts is asking a pointed question: does this transaction actually serve the public interest in Utah, where the utility's largest customer base resides? The answer, they suggest, is far from clear.

At the heart of the concern is cost allocation. PacifiCorp operates as a multi-state system, sharing generation resources and transmission infrastructure across its footprint. When a state like Washington exits the fold, the fixed costs of that shared infrastructure do not disappear—they are redistributed. Analysts warn that Utah ratepayers could absorb a disproportionate share of legacy costs, including those tied to coal-fired generation that Washington regulators had been pushing to retire more quickly.

Regulatory Arbitrage or Genuine Restructuring?

The sale also raises questions about regulatory strategy. Washington's commission has been increasingly assertive on climate mandates and rate design, while Utah's regulatory posture has historically been more accommodating. Some experts argue the divestiture is less about operational efficiency and more about regulatory arbitrage—moving assets to a jurisdiction with less stringent oversight. If that is the case, Utah's public interest may be harmed not only financially but also reputationally, as the state becomes the default home for assets other states no longer want.

Finally, there is the question of long-term reliability and transition risk. Removing Washington from the integrated resource plan could reduce the diversity of the generation portfolio, making the remaining system more dependent on a narrower set of resources. Utah consumers may face higher volatility in both prices and supply as the utility recalibrates. Until Utah's Public Service Commission conducts a rigorous, transparent review of these cross-subsidy effects, experts caution that approving the sale on the assumption of public benefit is premature. The burden of proof, they argue, should rest with the utility—not with the ratepayers who will live with the consequences.
