House Passes Ratepayer Protection Act Targeting AI Data Centers

The United States House of Representatives passed the Ratepayer Protection Act on September 16 in a 417-3 bipartisan vote. The legislation establishes a federal blueprint requiring state utility commissions to consider 'large load standards' for data centers using more than 100 MW of power. This framework aims to ensure that hyperscale operators cover the full incremental costs of generation, transmission, and distribution upgrades, preventing these expenses from being shifted to residential ratepayers and small businesses.

The bill follows a voluntary Ratepayer Protection Pledge from the White House and comes amid rising public backlash over utility bill spikes. While the act provides federal recommendations, it preserves state authority, meaning it encourages rather than mandates that state regulators adopt these rules. Some progressive Democrats and consumer groups, such as Public Citizen and Food & Water Watch, criticized the bill for lacking enforcement mechanisms and ignoring broader impacts on water resources and pollution.

Parallel to this legislative action, Duke Energy has faced allegations in Florida that its data center integration plans violate state law by shifting costs to residents. CEO Harry Sideris has denied these claims, asserting that data centers will have no impact on electricity bills. Meanwhile, in the Senate, Majority Leader John Thune and Senator Amy Klobuchar are developing a separate AI safety bill to address catastrophic risks from AI models. The Ratepayer Protection Act now moves to the Senate and requires the signature of President Donald Trump to become law.
