Washington moves to bind large data centers to resource and utility protections

Washington’s legislature approved a bill that requires large compute facilities to make binding resource, transparency and billing commitments as a precondition for operation. The measure covers sites drawing 20 megawatts or more and mandates annual disclosures of electricity, water and refrigerant use, plus greenhouse‑gas reporting, while directing utilities to adopt tariff or contract structures that prevent general ratepayers from absorbing incremental upgrade costs.

Supporters framed the bill as a corrective to rapid, concentrated compute growth — local data centers now show a collective peak draw near 1,414 megawatts — and pointed to accelerating hyperscaler capital spending as a driver of uncertain load trajectories. Legislators cited big cloud investments as context: Microsoft disclosed late‑2025 capital expenditures near $37.5 billion, while Amazon has signaled multiyear plans measured in the hundreds of billions, underscoring potential future demand.

Key provisions phase out free carbon‑credit treatment for covered operations starting in 2028 and narrow a sales‑tax break so replacement hardware is no longer exempt — a pair of changes lawmakers estimate will raise state revenue by roughly $63 million beginning in the next fiscal year. The House approved the bill on a 51–41 vote, with a handful of Democrats joining Republicans in opposition; the measure now moves to the Senate.

The Washington move is part of a broader national pattern: municipalities and some states have paused approvals, tightened interconnection rules, or proposed moratoria as communities press for clearer cost allocation and environmental safeguards. Industry tracking and several reporting outlets suggest roughly $64 billion of planned U.S. data‑center investment has faced postponement or modification amid permitting disputes and local pushback.

Across multiple jurisdictions, utilities and grid operators are conditioning large interconnections on defined upgrades, staged energization, or developer funding commitments to protect reserve margins and limit bill impacts for residential customers. Developers, in turn, are negotiating bespoke remedies — building substations, agreeing to connection fees, adding on‑site generation or storage, and committing to demand‑response — to blunt local opposition and reduce transmission strain.

Opposition to the Washington bill came from some trade groups, hosting municipalities that rely on data‑center property taxes, and the Data Center Coalition, which argued the industry is being singled out rather than included in broader grid modernization. Supporters — including some utilities and consumer advocates — said the measure increases transparency, reduces the risk of cross‑subsidization, and gives regulators clearer levers to align new loads with system planning.

Practical outcomes will hinge on how tariffs and contracts are designed: clear, enforceable staged‑connection terms and binding load forecasts can reduce rate‑case exposure and improve project sequencing, while weak rules risk either leaving consumers exposed or driving investment to more permissive states. The bill's success will therefore depend on coordinated transmission planning, accelerated clean‑energy buildout, and mechanisms that allocate upgrade costs in predictable ways.

Local officials in hosting communities emphasize economic benefits: new campuses deliver property‑tax revenues that have funded schools and services in towns like Quincy, complicating statewide tradeoffs between development and ratepayer protection. If the law prompts operators to accept steeper mitigation obligations, some projects could be delayed or redirected — mirroring patterns already visible in places such as Northern Virginia and parts of Texas.

Implementation details — especially around tariff design, the timing of required infrastructure work, and the treatment of on‑site mitigation — will determine whether the policy curbs hidden public costs or simply increases permitting friction. Observers expect negotiations among utilities, developers and local governments to accelerate as the sector adapts to both investor urgency and rising community scrutiny.

• Threshold for covered facilities: 20 MW
• Current collective peak demand (WA data centers): 1,414 MW
• Microsoft late‑2025 capex: $37.5B
• Amazon planned 2026 capex: $200B
• Estimated state revenue from tax change: $63M
• House vote on bill: 51–41
• Estimated U.S. data‑center projects delayed or reshaped by permitting/community disputes: $64B

This statute signals a policy shift: Washington is moving to treat large compute installations as active participants in grid planning and community resource management rather than as passive economic anchors. How the state, utilities and industry translate the new requirements into tariffs, contracts and upgrade schedules will shape where future AI infrastructure is sited and how its costs are allocated.
