Bill to curb AI data center utility costs hits snag in Senate

• The bill would establish an optional regulatory framework for states requiring data centers with 100+ megawatt demand to cover costs of new power infrastructure rather than passing them to consumers
• Around 1,000 major data centers are expected to be built in the next five years with over 2,000 projects currently proposed or tracked nationwide
• Heinrich blocked the bill in favor of his own proposal that would give FERC rulemaking authority over facilities demanding 150+ megawatts and mandate they pay for grid-related costs

Summary: Senate Blocks Bill on AI Data Center Utility Costs

A bipartisan legislative effort to limit utility cost increases from AI data centers stalled in the Senate on Thursday, despite overwhelming House support. The Ratepayer Protection Act passed the House 417-3 on Wednesday but was blocked by Sen. Martin Heinrich (D-N.M.), who argued the bill lacks sufficient enforcement mechanisms.

Key Details:

The Bill's Provisions:

• Would establish a voluntary regulatory framework for states
• Targets data centers with demand of 100+ megawatts
• Aims to require facilities to cover costs of new power infrastructure rather than passing expenses to consumers

Market Context:

• America expects to build the equivalent of 1,000 major data centers over the next five years
• Over 2,000 projects currently proposed or tracked
• Data centers have become increasingly contentious ahead of the 2026 midterm elections

Political Dynamics:

Sen. Heinrich blocked the measure citing concerns over voluntary compliance, proposing alternative legislation that would:

• Give the Federal Energy Regulatory Commission jurisdiction over facilities demanding 150+ megawatts
• Mandate (rather than suggest) that data centers pay for grid-related costs

Bill sponsor Sen. Husted (R-Ohio), facing a tight reelection race, plans to continue pursuing passage. The Senate's impending two-week departure makes advancement before the election unlikely.

Opposition: Progressive Democrats and environmental groups, including Food & Water Watch, criticized the bill as insufficient, calling it a "pointless" half-measure that merely suggests state action rather than mandating accountability.

The stalemate reflects growing national concern over AI infrastructure costs being transferred to residential ratepayers.
