Oregon Regulators Mandate Data Centers to Fully Fund Grid Expansion Costs, Ending Subsidies by Residential Ratepayers
Oregon’s utility regulator has approved landmark rules requiring data centers and other large industrial power users to bear the full cost of electricity grid infrastructure they necessitate, effectively ending a long-standing arrangement where residential and small business customers subsidized the technology sector’s rapid expansion. The Oregon Public Utility Commission (PUC) published the new order on May 5, 2026, following requests from utilities and a legislative directive under House Bill 3546, known as the Protecting Oregonians With Energy Responsibility (POWER) Act. Portland General Electric (PGE), the state’s largest utility by customer count, must file a new pricing framework by June 3, with rates taking effect on June 10.
The decision addresses a growing disparity in electricity costs across Oregon. Before the new rules, data center customers on PGE’s network paid approximately 8 U.S. cents per kilowatt-hour (kWh), while residential customers paid more than double that amount—close to 20 cents per kWh—according to the Oregon Citizens’ Utility Board (CUB), a nonprofit ratepayer watchdog. CUB found that data centers have been a significant driver of rising PGE bills, which have increased by nearly 50% over the past five years. The organization estimated that PGE spent $210 million in the past year attributable to data center growth in Hillsboro, Oregon. “We are confident that by this summer, we will see data centers paying higher rates that more accurately reflect the costs they are putting on our energy grid,” said CUB executive director Bob Jenks.
The order establishes obligations for large energy use facilities, defined as those capable of drawing 20 megawatts (MW) or more at a time—enough to power approximately 800 homes based on regional average usage figures from the Northwest Power and Conservation Council. These facilities must enter contracts making them responsible for 100% of distribution network expansion costs. They are also required to use at least 90% of their contracted power capacity and face financial penalties for exceeding contracted usage or exiting contracts early. A further tier, designated “very large loads,” applies to customers capable of drawing 100 MW or more, who face a surcharge of 1 cent per kWh, with revenue directed toward energy efficiency upgrades for low-income households. The order also includes a queue system requiring that sufficient zero-emission generating capacity be in place before any new data center can connect to the grid, ensuring compliance with House Bill 2021, which mandates that Oregon utilities eliminate greenhouse gas emissions from electricity generation by 2040.
PGE’s chief customer officer John McFarland said the decision was an important step toward balancing growth, reliability, and affordability. “As energy demand grows, it is critical that the costs of new infrastructure are allocated fairly and transparently,” McFarland said. The order also allows PGE to enter special contracts with large customers who wish to front-load infrastructure costs in exchange for faster equipment commissioning. PGE must submit annual reports detailing the size, energy demand, and emissions of all large-load customers, with the first report due June 1, 2027. Additionally, the order imposes renewable energy requirements on data centers before they come online and introduces exit fees for facilities that abandon projects before completion, designed to prevent cost stranding—situations where ratepayers are left to service grid infrastructure built for customers who subsequently withdraw. “While the Commission has long sought to avoid unwarranted cost shifting between customer classes, the scale of data centres and the rate at which they are requesting service from PGE create unique versions of otherwise well-understood risks,” the commission wrote.
The Data Center Coalition, a national membership association representing 42 data center owners and operators, criticized the framework as excessive. Vice president of energy Aaron Tinjum described the order as “out of step” with other states and said it contained the most extreme protective mechanisms he had seen in any jurisdiction. Tinjum said his members support fair cost allocation and are committed to funding transmission and clean energy infrastructure, but argued the order risked undermining Oregon’s competitiveness. “We really want those to be evidence-based and balanced in the sense that if a company wants to invest in Oregon, that they still have a pathway for doing that,” Tinjum said. In contrast, Cole Souder, staff attorney at the Green Energy Institute at Lewis and Clark Law School, said the order would hold data centers accountable for commitments they had already publicly made. “Data centres will recognise that Oregon is a place where, if they want to connect there, they actually have to uphold their statements, their commitments to taking on the cost they impose, their commitments to being good neighbours, and their commitments to not polluting and to use renewable energy,” Souder said.
Oregon PUC Chair Letha Tawney said the ruling protects ordinary Oregonians from bearing the costs of rapid data center expansion. “This decision ensures the largest energy users in PGE’s service area pay their fair share, have clarity and predictability as they make business decisions and support the programmes that keep our grid reliable and our communities strong,” Tawney said. Oregon hosts more than 120 data centers and is among a small number of states that have enacted legislation to protect ratepayers from the electricity cost implications of that growth. The POWER Act, passed in June 2025, created a new customer classification for large industrial energy users—including data centers and cryptocurrency mining operations—and directed utilities to charge them accordingly. PGE is the first Oregon utility to implement a POWER Act-specific rate structure for data centers, while Pacific Power, the state’s other major investor-owned utility, had a comparable large-load tariff approved in its 2024 general rate case. The order applies only to new large-load connections or expanded contracts, with existing facilities below the 20 MW threshold unaffected by the current framework.
Oregon’s approach stands in contrast to jurisdictions that have prioritized data center attraction through tax incentives and subsidized infrastructure, effectively distributing the cost of technological growth across general ratepayers or public budgets. This tension is not unique to the United States. Singapore, which hosts a significant concentration of regional data center infrastructure and lifted a moratorium on new facilities in 2022 with sustainability conditions attached, has continued to expand electricity generation capacity to accommodate projected demand from the sector. Unlike Oregon’s model—in which regulators explicitly assign infrastructure costs to the large users generating demand—the costs of that generation expansion in Singapore have predominantly been absorbed through broader state infrastructure funding rather than direct cost allocation to the sector itself. As AI-driven industries accelerate electricity consumption globally, the question of who bears the cost of the energy infrastructure they require is becoming a central regulatory and political issue. Oregon’s answer, at least for now, is unambiguous: the users generating the demand should pay for the grid that serves them.
