U.S. House Passes Bipartisan Ratepayer Protection Act (417–3) to Shield Consumers from 100+ MW Data Center Substation Costs
Amending PURPA, the landmark legislation mandates that hyperscale data centers requiring 100+ MW grid interconnects finance 100% of dedicated substation transformers and transmission lines, preventing utility cost-shifting onto residential rate bases.

Bipartisan Mandate to Insulate Households from Hyperscale Grid Expansion Costs
On September 16, 2026, the United States House of Representatives passed the bipartisan Ratepayer Protection Act (H.R. 9340) by an overwhelming 417-to-3 vote. The fast-tracked legislation addresses mounting consumer backlash against rising electricity tariffs tied to grid buildouts for artificial intelligence infrastructure.
The bill establishes federal guidelines preventing electric utilities from spreading the capital expenditures of dedicated transmission spurs, high-capacity substation transformers, and grid interconnections across general retail rate bases.
Amending PURPA Standards for 100+ Megawatt Interconnection Tariffs
The act amends the Public Utility Regulatory Policies Act of 1978 (PURPA), directing state public utility commissions (PUCs) to consider enacting mandatory large-load customer classes for facilities demanding 100 megawatts or greater.
Under the proposed framework, data center operators must directly fund 100% of the incremental substation and transmission assets required to serve them, alongside posting financial security and collateral to protect utilities against stranded asset risks should facility operations downscale.
