The Oregon House of Representatives on April 22, 2025, passed House Bill 3546 by a vote of 41-16, legislation designed to shield residential electricity customers from bearing infrastructure costs driven by data center expansion. The bill grants the Oregon Public Utility Commission (PUC) authority to require data centers to pay for grid upgrades and capacity additions that their operations necessitate, rather than spreading those costs across all ratepayers.

Data centers consumed approximately 11 percent of Oregon's electricity as of the vote date, according to legislative testimony. Portland General Electric (PGE) reported supplying more than 1 million megawatt-hours to data centers in 2023, a figure that had doubled from two years earlier. The rapid growth has strained grid capacity and raised concerns about cost allocation among lawmakers and consumer advocates.

Governor Tina Kotek indicated support for the measure, stating she would sign the bill if it reaches her desk. The legislation now moves to the Oregon Senate for consideration.

Representative Dacia Grayber, a sponsor of the bill, stated during floor debate: "The people of Oregon should not foot the bill for data centers straining the power grid." The bill requires new data centers to commit to a minimum 10-year operational period before connecting to the grid, a provision aimed at preventing speculative projects from triggering infrastructure investments that ratepayers would ultimately fund.

The measure applies to investor-owned utilities including PGE and PacifiCorp. Electric cooperatives in Oregon already possess similar authority under existing regulations.

The Oregon House convened on April 22, 2025, to vote on HB 3546, a bill that had advanced through committee with bipartisan support despite opposition from technology industry representatives. The final vote of 41-16 reflected a coalition of Democrats and some Republicans concerned about utility rate impacts on residential customers.

HB 3546 emerged from months of legislative discussion following reports of accelerating data center development across Oregon. Amazon Web Services announced in February 2025 an expansion plan covering 400 acres in Arlington, Oregon, adding to existing facilities operated by Google, Meta, and other technology companies in the state.

The bill's core mechanism grants the Oregon PUC discretionary authority to allocate infrastructure costs. Under current regulations, utilities typically spread capital investments across their entire customer base through rate cases. HB 3546 allows the PUC to instead assign costs directly to large commercial customers whose demand triggers the need for new generation, transmission, or distribution infrastructure.

Representative Grayber introduced the bill in January 2025, citing constituent concerns about rising electricity rates. Testimony during committee hearings included data showing PGE's data center load had grown from approximately 500,000 megawatt-hours in 2021 to over 1 million megawatt-hours in 2023.

Legislative Claims:

The bill's sponsors presented several key arguments during floor debate. Representative Grayber stated that data centers represent a concentrated source of demand growth that differs fundamentally from residential or small commercial load increases. She cited PGE filings showing data center customers account for a disproportionate share of peak demand relative to their contribution to fixed cost recovery.

Utility Data:

PGE's 2024 integrated resource plan, referenced in committee testimony, projected continued data center load growth through 2030. The utility indicated that meeting this demand would require investments in both generation capacity and transmission infrastructure, with preliminary cost estimates in the hundreds of millions of dollars.

Industry Response:

Technology industry representatives testified against the bill during committee hearings. The Oregon Technology Association argued that the measure could discourage data center investment in the state, potentially pushing projects to neighboring states with more favorable regulatory environments. Industry witnesses noted that data centers provide tax revenue, construction jobs, and ongoing employment.

10-Year Commitment Requirement:

The bill includes a provision requiring new data centers to commit to at least 10 years of operation before connecting to utility service. Sponsors described this as a protection against speculative projects that might trigger infrastructure investments and then relocate or close, leaving other ratepayers to cover stranded costs.

Consumer Protection:

The primary benefit cited by supporters involves protecting residential and small business ratepayers from subsidizing infrastructure built primarily to serve large commercial customers. Under traditional rate-making, all customers share capital costs proportionally, regardless of which customer class drives the need for investment.

Cost Causation Alignment:

The bill aligns with the regulatory principle of cost causation, which holds that customers should pay for the infrastructure their usage requires. Supporters argued this approach creates appropriate price signals for data center operators when selecting locations and designing facilities.

Grid Planning Incentives:

By requiring data centers to internalize infrastructure costs, the bill creates incentives for operators to site facilities where grid capacity exists, to invest in on-site generation or storage, or to implement demand management strategies that reduce peak load impacts.

Precedent for Other States:

Oregon's action provides a template for other states experiencing rapid data center growth. Legislators from Washington and Nevada have reportedly contacted Oregon lawmakers about the bill's structure and implementation mechanisms.

Economic Development Concerns:

Opponents argued the bill could reduce Oregon's competitiveness for data center investment. The technology industry has become a significant economic driver in the state, and companies have options to locate facilities in jurisdictions with lower regulatory burdens.

Implementation Complexity:

The bill grants discretionary authority to the PUC rather than establishing fixed rules. Critics noted this creates uncertainty for both utilities and data center operators, as cost allocation decisions will depend on case-by-case PUC determinations.

Existing Contracts:

The bill's application to existing data center operations remains unclear. Facilities operating under long-term service agreements with utilities may argue those contracts establish cost allocation terms that cannot be retroactively modified.

Definitional Challenges:

The legislation defines data centers based on power consumption thresholds, but the boundary between data centers and other large commercial facilities is not always clear. Manufacturing facilities with significant computing operations, for example, might fall into regulatory gray areas.

Data Center Power Consumption:

Modern data centers consume electricity for three primary purposes: computing equipment, cooling systems, and supporting infrastructure. A typical hyperscale facility operates at power densities of 10-30 megawatts, with the largest campuses exceeding 100 megawatts of total capacity.

Grid Infrastructure Requirements:

Serving data center loads requires utilities to maintain adequate generation capacity, transmission lines capable of delivering power to facility locations, and distribution infrastructure sized for concentrated high-density loads. Each component involves capital investments that utilities recover through customer rates.

Cost Allocation Mechanisms:

Traditional utility rate-making spreads capital costs across customer classes based on factors including energy consumption, peak demand contribution, and customer count. HB 3546 allows the PUC to deviate from this approach for data center-driven investments, assigning costs more directly to the customers whose demand necessitates the infrastructure.

Technical Context (Optional):

Power engineers measure data center efficiency using Power Usage Effectiveness (PUE), the ratio of total facility power to computing equipment power. Industry-leading facilities achieve PUE values near 1.1, meaning cooling and infrastructure consume only 10 percent of total power. Less efficient facilities may have PUE values of 1.5 or higher, significantly increasing grid impact per unit of computing capacity.

National Infrastructure Debate:

Data center power consumption has become a national infrastructure concern as artificial intelligence workloads drive demand growth. The Department of Energy projected in 2024 that U.S. data center electricity consumption could double by 2030, raising questions about grid capacity and cost allocation across multiple states.

Utility Business Model:

The bill reflects broader tensions in utility regulation as large commercial customers increasingly drive infrastructure investment. Traditional rate-making assumes relatively homogeneous customer bases, an assumption that concentrated data center loads challenge.

State Competition Dynamics:

Oregon's action occurs within a competitive landscape where states actively recruit data center investment through tax incentives, expedited permitting, and favorable utility rates. The bill's impact on Oregon's competitive position will be closely watched by economic development officials in other states.

Renewable Energy Intersection:

Many data center operators have committed to renewable energy procurement, creating complex interactions with grid planning. Facilities that contract for renewable power may argue they should not bear costs for conventional generation infrastructure, while utilities note that intermittent renewable sources require backup capacity.

Confirmed:

The House passed HB 3546 by a 41-16 vote on April 22, 2025. Governor Kotek has indicated she will sign the bill if it passes the Senate. The bill grants PUC authority to allocate data center infrastructure costs but does not mandate specific allocation formulas. Data centers consumed approximately 11 percent of Oregon's electricity at the time of the vote.

Unclear:

The Senate timeline for considering the bill has not been announced. How the PUC will exercise its new authority remains to be determined through future rulemaking proceedings. The bill's impact on pending data center projects, including Amazon's Arlington expansion, is uncertain. Whether existing data center operations will be affected depends on PUC interpretation of the legislation.

Senate Action:

The Oregon Senate will consider HB 3546 in coming weeks. Industry lobbying efforts are expected to intensify, and amendments remain possible during Senate consideration.

PUC Rulemaking:

If the bill becomes law, the PUC will need to develop implementation rules specifying how cost allocation determinations will be made. This process typically involves public comment periods and stakeholder workshops.

Industry Response:

Data center operators' investment decisions in Oregon will signal how the industry interprets the bill's impact. Announcements of project delays, relocations, or cancellations would indicate significant concern, while continued investment would suggest the industry views the regulatory change as manageable.

Other State Actions:

Legislators in Washington, Nevada, and Virginia have expressed interest in similar measures. Oregon's experience will inform policy discussions in these states as they address their own data center growth challenges.
