The Oregon Public Utility Commission has approved a 29.7% electricity rate increase for Portland General Electric customers consuming over 20 MW, in line with the state's POWER Act. This decision significantly impacts the power economics for AI training and inference clusters in the Pacific Northwest's densest data center corridor.
HB 3546, effective June 16, 2025, establishes a separate rate class for hyperscale loads. As Oregon's largest utility and the first to implement the act, PGE now requires facilities exceeding the 20 MW threshold to enter into contracts of 10 to 30 years, pay deposits on new service, and fund 90% of contracted demand irrespective of actual consumption. Operators are also required to cover the full lifetime cost of any new transmission infrastructure built to serve them. The commission added penalties of 1.5x on energy and 4x on transmission for usage above plan, along with exit fees for early termination. Previously, large industrial customers paid around 8 cents per kilowatt-hour, compared to nearly 20 cents for residential users; the new rate raises industrial power to roughly 10 cents — calculated from the 8¢ baseline plus the 29.7% increase — while residential users see a modest decline. Climate Solutions notes that PGE rates rose nearly 60% since 2020.
Oregon is home to more than 135 data centers, with PGE investing $210 million in grid expansion in Hillsboro. A 30 MW facility now carries the load profile of the city of Ashland; a 250 MW AI campus matches Eugene. Under the new rules, the 250 MW cluster must commit to paying for roughly 225 MW of baseline supply, regardless of GPU utilization, and any training burst over plan triggers transmission penalties that can erase model-training budget forecasts. Facilities over 100 MW also incur a surcharge to fund low-income household energy-efficiency upgrades.
Workload elasticity is most affected, as the 90% take-or-pay demand commitment eliminates savings from scaling down inference fleets during off-peak hours, and the 4x transmission penalty turns unpredictable training spikes into balance-sheet liabilities. The Clean Energy Safeguard adds schedule risk by tying new data center interconnections to clean generation availability rather than construction timelines. Oregon CUB reported that more than 70,000 Oregon households were disconnected for nonpayment across the state's major utilities in 2024 — a record since tracking began — with PGE alone accounting for more than 32,000 disconnections just through October of that year, both figures attributed to data center load growth on the shared grid, and Governor Tina Kotek framed the act as a win for residents over infrastructure operators. AWS and the Data Center Coalition warned that the regime would drive builds to other states, a threat already materializing in Montana, where HB 424 offers favorable tax treatment to co-located power generation, and in Washington, where Governor Ferguson's Executive Order 25-05 is assessing large-load impacts on state tax revenue. Climate Solutions notes that PacifiCorp's parallel proceeding, with a decision expected in November 2026, would extend similar rules to roughly two-thirds of Oregon's utility customers.
For AI infrastructure teams, power contracts should be treated as rigid reserved-instance commitments with severe overage penalties, not metered cloud compute. If already in a Hillsboro co-lo, audit your PGE contract for demand-commitment floors and exit-liability exposure before the next reservation cycle; if greenfielding, model the per-GPU-hour delta across Oregon, Montana, and Washington, as a 29.7% base-rate hike with a 10-year lock-in has turned geographic arbitrage from an optimization into a survival calculation.
