Oregon utility to review PGE plan over data center cost concerns

Portland General Electric is facing a challenge from the Oregon Citizens Utility Board, which says PGE’s proposed cost-allocation framework would effectively sidestep the state’s POWER Act by shifting an estimated 34–45% of new supply and transmission costs onto residential customers (CUB cites one example assigning 47% of two $174m substations to households). PGE defends the plan, proposing a “Peak Growth Modifier,” a rolling three‑year lookback to allocate shared infrastructure costs to the customer classes driving peak demand and saying the new data‑center rate class (Schedule 96) would see rate increases of roughly 25% while other classes could fall; PGE will file a revised proposal this week. The Oregon Public Utility Commission will rule by April 2026; CUB warns the proposal contradicts legislative intent, could worsen affordability amid recent ~50% residential rate jumps, and creates regulatory and political risk over how long‑lived grid investments for rapidly growing data centers (forecast to reach ~20% of state consumption by 2030) will be paid for.

Analysis

The Oregon Citizens Utility Board (CUB) alleges Portland General Electric (PGE) is effectively sidestepping the POWER Act by proposing a cost-allocation framework that would assign 34–45% of new power supply and transmission costs to residential customers; CUB cited an example where PGE’s methodology would allocate 47% of two $174 million substations—built exclusively for data centers—to households. PGE defends the approach with a “Peak Growth Modifier,” a rolling three-year lookback the company says will more precisely assign shared infrastructure costs to the customer classes driving peak demand, and PGE says the new data-center rate class (Schedule 96) could see rate increases of roughly 25% while other classes could see reductions. The Oregon Public Utility Commission is reviewing PGE’s revised filing with a decision due by April 2026, creating a protracted regulatory and political process that will determine final cost allocation and customer impacts.

The core dispute is methodological and temporal: CUB contends the three-year lookback understates the multi-decade life of grid investments and shifts long-term costs onto residential ratepayers already facing roughly 50% rate increases in recent years. PGE emphasizes the modifier applies to shared infrastructure, not customer-specific assets, but CUB points to substations that serve only data centers as evidence the proposal may preserve cross-subsidies. With data centers currently ~6% of Oregon consumption and projected to reach ~20% by 2030, the resolution will materially affect rate design, affordability dynamics, and PGE’s regulatory risk profile.

For investors, this is a governance and regulatory-risk event for POR: the outcome can change revenue allocation, customer rate pressure, and reputational exposure. Key near-term catalysts are PGE’s revised filing and the OPUC’s April 2026 decision; market impact is currently mildly negative but outcome-dependent, so investors should monitor filings, stakeholder comments, and any interim settlements closely.

Key Decisions for Investors

• Monitor PGE’s revised filing and the OPUC docket closely and reassess POR exposure after the April 2026 decision
• If long POR, consider hedging or trimming positions given regulatory and political uncertainty around cost allocation and potential rate-rebased earnings volatility
• Watch Schedule 96 rate design and CUB regulatory challenges as a determinant of how much cost shifts to residential customers versus data centers and stress-test portfolio scenarios accordingly
• Track public statements and any interim settlements between PGE, CUB, and regulators since those signals will materially change legal and reputational risk premia
