Senator Martin Heinrich blocks bill to shield consumers from data center electricity costs

Democratic Senator Martin Heinrich blocked the fast-track passage of the Ratepayer Protection Act in the Senate on September 17, 2026, just one day after the bill passed the House in an overwhelming 417-3 vote. The bill, sponsored by Republican Senator Jon Husted, would establish a federal standard for state regulators to ensure data centers consuming over 100 megawatts pay for their own grid upgrades. Heinrich argued the bill lacks teeth because it is voluntary for states, advocating instead for his GRID Savings Act to mandate cost-sharing via FERC, which Republicans subsequently blocked.

Heinrich blocks Senate passage

• ▪Democratic Representatives Summer Lee, Delia Ramirez, and Rashida Tlaib were the only three members of the House of Representatives to vote against the Ratepayer Protection Act.
• ▪The Ratepayer Protection Act passed the United States House of Representatives on September 16, 2026, with an overwhelming bipartisan vote of 417 to 3.
• ▪United States Senator Martin Heinrich blocked a unanimous consent request on September 17, 2026, to fast-track the Ratepayer Protection Act in the Senate.

Ratepayer Protection Act provisions

• ▪The Ratepayer Protection Act would establish a federal standard requiring large-load electricity customers drawing 100 megawatts or more to cover the full incremental costs of grid and generation upgrades.
• ▪The Ratepayer Protection Act would amend the Public Utility Regulatory Policies Act of 1978 to require state utility regulators to consider the cost-allocation standard within one year and decide on adoption within two years.
• ▪The Ratepayer Protection Act would codify portions of President Donald Trump's voluntary Ratepayer Protection Pledge, which has been signed by over 300 utilities, electric cooperatives, and hyperscalers.

Data center electricity cost concerns

• ▪Average household electricity bills in the United States have increased by approximately 13% since the start of the Trump administration, driven in part by the rapid expansion of data centers for artificial intelligence workloads.
• ▪An Economist/YouGov poll conducted from August 28 to 31, 2026, found that 60% of United States adult citizens believe a new data center in their community would increase their electricity bills.
• ▪A Bowling Green State University poll found that 75% of likely voters in Ohio oppose the construction of data centers in their local communities.

Voluntary versus mandatory enforcement debate

• ▪Senator Martin Heinrich objected to the Ratepayer Protection Act because it only requires states to consider the standard, calling the framework voluntary and insufficient for real consumer protection.
• ▪Mitch Jones of the advocacy group Food & Water Watch opposed the Ratepayer Protection Act, calling it pointless legislation that merely suggests states should act.
• ▪Senator Jon Husted argued that failing to pass the Ratepayer Protection Act would fuel public opposition to data centers, slow construction, and allow China to gain a competitive ground in technology.

Heinrich's alternative GRID Savings Act

• ▪The GRID Savings Act explicitly exempts the Electric Reliability Council of Texas, which operates independently from the two major United States electrical interconnections.
• ▪Senator Martin Heinrich promoted his alternative bill, the GRID Savings Act, which would empower the Federal Energy Regulatory Commission to impose mandatory cost-responsibility rules on electricity users exceeding 150 megawatts.
• ▪Republican Senator Bernie Moreno blocked Senator Martin Heinrich's request to fast-track the GRID Savings Act, accusing Democrats of obstruction.

Debatable claims

• ▪Local communities should block the construction of new data centers
• ▪Congress should mandate that data centers pay for grid upgrades
