U.S. House Passes Ratepayer Protection Act Requiring Data Centers to Cover Incremental Grid Costs

The U.S. House of Representatives on Sep. 16 approved the Ratepayer Protection Act, sending legislation to the Senate that would require large electricity customers to bear the full cost of grid upgrades built specifically to serve their facilities. The measure passed with broad bipartisan support, reflecting growing concern that the rapid expansion of data centers and other high-demand industrial projects could shift infrastructure costs onto existing utility customers.

The legislation would amend the Public Utility Regulatory Policies Act of 1978 by establishing a new federal ratemaking standard for non-residential customers with a peak electricity demand of 100 megawatts or more at a single site or campus. Utilities would be required to recover the full incremental cost of generation, transmission, and distribution upgrades needed to serve those customers, including if a customer later terminates its contract or stops purchasing electricity before the investment is recovered.

The proposal would also require utilities to obtain financial assurances or upfront contributions before constructing qualifying infrastructure, reducing the risk of stranded investments being passed on to residential and small-business customers. The standard is intended to ensure that new, energy-intensive developments pay for the infrastructure they require rather than spreading those costs across existing ratepayers.

The measure preserves the existing state-based framework under federal utility law by requiring state utility regulators and publicly owned utilities to consider the new standard through formal proceedings. States that have already adopted or reviewed comparable cost-allocation policies would be exempt from repeating that process.

The legislation follows a broader wave of state action as regulators respond to rapid data center-driven load growth. In July, New Jersey enacted the Data Center Fair Share Act, requiring utilities to create a separate rate structure for large data centers, assign associated grid infrastructure costs to those customers, and strengthen protections for other ratepayers. In May, Maryland created a separate rate class for large load customers, while Pennsylvania advanced a statewide tariff in April requiring qualifying projects to fund dedicated grid upgrades and provide financial assurances.

Other states are pursuing similar protections through regulatory action. Last month, Michigan recommended codifying protections requiring data centers to cover 100 percent of the costs they impose on the grid, including transmission upgrades. Minnesota approved a dedicated customer class with long-term payment obligations, while New York is reviewing interconnection, tariff, and cost-allocation reforms to ensure new infrastructure costs are not shifted to existing customers.
