Walk the server rows of a large facility outside Hillsboro on any given night and the hum is constant, industrial, enormous.
That draw never stops, and for years the grid bill for it was quietly shared.
Households subsidized the infrastructure that made Oregon attractive to the tech industry.
State regulators just ended that arrangement.
How did a structural cost mismatch survive so long, and what finally forced the math into the open?
Why data centers had been getting a cheaper deal than your kitchen lights
The mechanism is straightforward once you see it. Utilities build infrastructure, substations, transmission lines, grid upgrades, to meet the demand of whoever is connecting. When a single data center pulls 20 megawatts or more from the local grid, it forces the utility to build expensive new power infrastructure that ordinary ratepayers would ultimately help fund.
But those construction costs were pooled across all customer classes, which meant every household quietly chipped in. The PUC’s decision ensures that data centers’ utility bills reflect the specific costs of serving their loads and protects residential and commercial customers from subsidizing the infrastructure needed for rapid large-load growth.
So households were, in effect, financing the grid expansions that made Oregon attractive to the tech industry. The Protecting Oregonians With Energy Responsibility (POWER) Act was passed by the state legislature and signed into law in 2025, the first-in-the-nation state legislation to make data centers accountable for paying the energy and infrastructure costs incurred for their own operations.
The Oregon law that created an entirely new customer class for large power users
In 2025, the Oregon Legislature adopted the Protecting Oregonians With Energy Responsibility (POWER) Act (HB 3546) with bipartisan support. It creates a new classification for data centers, cryptocurrency and other large industrial energy users drawing more than 20 megawatts, requiring them to pay for their share of electricity use and costs. To put that threshold in context, a 30-megawatt data center uses as much electricity as the City of Ashland.
Portland General Electric, Oregon’s largest electric utility, was the first to act on that mandate. PGE submitted its filing on June 3 to comply with the order that followed the Commission’s investigation into the treatment of large-load customers and established new rate structures for data centers under the POWER Act. The Oregon Public Utility Commission unanimously approved Portland General Electric’s rate hike for large energy users on July 7, to take effect the following day, with residential rates going down 1.3%. The decision creates Schedule 96, a new rate class required under House Bill 3546 (2025), known as the POWER Act, to ensure that the fast-growing electricity needs of data centers do not contribute to increasing utility bills for Oregon households and small businesses. A separate proceeding covering PacifiCorp’s Pacific Power territory, where facilities including Amazon’s Boardman campus and Google’s installation at The Dalles operate, has started at the Public Utility Commission, with regulators expected to make a decision in November 2026.
The law’s passage had been contentious. As of 2025, PGE had spent $210 million on data center growth in Hillsboro alone, making Hillsboro, already the center of Oregon’s data center cluster, the site of community concern over the industry’s power appetite. The POWER Act emerged from that tension as a legislative answer.
What the approved rate order actually says, and who pays what
The decision affects about 963,000 customers across PGE’s service territory, with changes starting July 8. The final approved rate increase for data centers settled at 29.7 percent.
Residential rates decreased 1.3 percent, commercial customers see an average decrease of 2.1 percent, and industrial customers save an average of 1.4 percent. A typical residential customer using 780 kilowatt-hours will save about $1.91 each month. That is modest on any individual bill, but it represents the reversal of a cross-subsidy that had been flowing the wrong direction across hundreds of thousands of households for years.
In addition to creating Schedule 96, the PUC adopted new contract requirements that will apply to all future agreements between PGE and data center customers, including predictable charges if a data center does not use the infrastructure PGE has built to serve them. This fits a broader national pattern: investor-owned utilities have been pressing for rate restructuring across dozens of states.
Where the new rate structure runs into real complications
The 29.7 percent figure sounds decisive, but the POWER Act left the most contested question open. The law directed regulators to make data centers bear the costs of their own interconnection without specifying a precise formula, so the precise cost allocation is still being worked out in ongoing regulatory proceedings. That means the approved tariff is a floor, not a ceiling.
There is also a timing issue. The order includes contracts ranging from 10 to 30 years, depending on project size, and data centers already connected before the POWER Act took effect are not automatically subject to the same framework as new entrants. Oregon’s pipeline of projects under construction is significantly larger than those currently reclassified, with their status under the new rules still being resolved.
Even the residential savings have a catch. PGE simultaneously has a separate general rate case pending, proposing a residential increase for the following year to fund grid reliability upgrades unrelated to data center growth. So the modest reduction may be partially absorbed by costs coming from a different direction. Tracking those competing pressures alongside the wider push to add utility-scale battery storage across the US grid shows just how many rate cases are moving through state commissions at once.
What this tariff model could mean for the rest of the country
The Oregon Public Utility Commission order is the first major implementation of Oregon’s 2025 POWER Act in Portland General Electric territory. Analysts said the framework, Schedule 96, provides regulatory certainty for utility investment while limiting cost shifts to other customers, potentially creating a model for other utilities facing rapid data center growth, as Oregon is among the latest states to adopt a large-load tariff aimed at protecting existing ratepayers from the costs of interconnecting large-load customers.
The POWER Act model offers one answer: define a new customer class, require it to pay for its own grid footprint, and stop pooling growth costs across unrelated ratepayers. The law was intended to prevent small customers from subsidizing data center infrastructure and to get the industry to pay its fair share. Whether other state legislatures follow depends partly on how cleanly the new tariff holds up as the first facilities begin paying under it.
Several states with large data center clusters are watching the Oregon outcome closely. The POWER Act framework gives them a legislative template that has now cleared both a state legislature and a utility commission. The gap between what large industrial power users pay and what households pay exists in nearly every regulated territory in the country. Oregon just put a dollar figure on closing it.
