The Oregon Public Utility Commission (OPUC) became the first US state regulator to approve a full-cost large-load rate filing under a dedicated cost-attribution law when it approved Portland General Electric's POWER Act tariff on 7 July 2026, effective 8 July. The approved tariff sets a 29% rate increase for data-centre customers at or above 20 MW and a 1.3% cut for households. OPUC chair Letha Tawney had delayed the decision from 10 June, citing approximately 200 pages of tariff updates requiring staff review.
OPUC is a three-member commission appointed by the governor, with authority to set rates, approve infrastructure investments, and regulate service standards for electric, gas, and telecommunications utilities in Oregon. It is the counterpart to bodies such as Virginia's State Corporation Commission and Texas's Public Utility Commission. Tariff proceedings typically involve public comment periods and can take months to resolve.
The 7 July approval is now the first national precedent for whether the POWER Act model survives regulatory scrutiny and industry pushback. Legislators in at least a dozen other US states have a live regulatory precedent and a working tariff structure to cite, and OPUC's decision on any subsequent appeal will determine how durable that precedent proves to be.
