Senate Democrat Blocks Data Center Bill; Trump Pushes Thune for Floor Vote

Senator Martin Heinrich blocked the Ratepayer Protection Act on Thursday, killing a fast-track Senate vote just one day after the House passed it 417-3. The bill would require state utility regulators to consider whether large data center operators consuming 100 megawatts or more should bear the cost of new energy infrastructure. Heinrich said the bill relies too heavily on voluntary commitments from states and tech companies. President Trump is now pushing Senate Majority Leader John Thune to bring the measure to the floor for a full vote.

Why Heinrich blocked the bill

Senator Martin Heinrich, New Mexico’s top Democrat on the Senate Energy and Natural Resources Committee, objected to the unanimous consent procedure on Thursday. He argued the Ratepayer Protection Act does not go far enough because it only requires states to consider making data centers pay for grid upgrades, rather than mandating they do so. Heinrich said Congress needs “real legislation with real teeth,” not voluntary pledges from tech companies.

What the House bill requires

The House passed the Ratepayer Protection Act 417-3 on Wednesday under a fast-track procedure. The bill would require state utility regulators to consider whether large electricity users, including data centers, should bear the incremental costs of power infrastructure built to serve them. Only three progressive Democrats opposed it: Reps. Summer Lee of Pennsylvania, Delia Ramirez of Illinois, and Rashida Tlaib of Michigan.

Heinrich’s alternative and Republican pushback

After blocking the Republican bill, Heinrich sought unanimous consent for his own GRID Savings Act of 2026, which would vest the Federal Energy Regulatory Commission with authority over any facility pulling 150 megawatts or more from the grid and obligate such operations to absorb infrastructure costs. Senator Bernie Moreno, a Republican from Ohio, objected to Heinrich’s proposal. With the Senate set to leave Washington in two weeks before midterm elections, the bill is unlikely to advance before November, according to CNBC.

Trump backs data centers and pushes for Senate action

President Trump said Friday he is engaging with Republican Senate Majority Leader John Thune about bringing the bill to the floor. Trump strongly backs data center development as critical to artificial intelligence leadership, calling data centers the “oil of the next 20, 25 years.” A recent poll by the University of Massachusetts Amherst found just 11% of Americans would support construction of an AI data center in their community, reflecting growing public concern over rising electricity costs and grid strain.

Final Thoughts

The bill’s fate now rests with Senate Majority Leader Thune and Trump’s political capital. With only two weeks left before the midterm recess, passage remains uncertain despite overwhelming House support and Trump’s backing.
