The White House expanded its Ratepayer Protection Pledge to 23 governors and at least 187 companies, but it did not create enforceable bill protections.
Governors, utilities and data-center developers joined a nonbinding commitment meant to prevent AI growth from raising household electric bills.
President Donald Trump convened governors, utilities and data-center companies to expand a voluntary pledge intended to shield consumers from AI-related electricity costs.
The White House said 23 governors and at least 187 companies had signed, including 55 utilities and 27 data-center developers.
Utility signers included NextEra Energy, Duke Energy, American Electric Power, Southern Company and Pacific Gas and Electric.
Developers Equinix, Digital Realty and Prologis joined technology companies that had signed the earlier version.
Google, Microsoft, Meta, Oracle, xAI, OpenAI and Amazon were among the companies already committed to the pledge.
The pledge remained nonbinding and did not itself change state rate cases, utility tariffs or the allocation of transmission and generation costs.
Data-center expansion is increasing electricity demand and has become a major component of U.S. capital spending.
Electricity regulation is divided among states, regional grid operators and federal agencies, limiting what a single voluntary national statement can accomplish.
Some technology companies supporting the pledge have opposed state legislation that would impose mandatory protections, according to a consumer advocate quoted by AP.
The evidence supports a bounded conclusion: The White House expanded its Ratepayer Protection Pledge to 23 governors and at least 187 companies, but it did not create enforceable bill protections. It does not resolve the remaining uncertainty because No uniform accounting method showed what costs signers would absorb or how claimed customer savings would be verified. The factual horizon is therefore defined by State rate decisions involving data-center costs and Publication of measurable compliance reports by pledge signers.
The current reporting limit is specific: No uniform accounting method showed what costs signers would absorb or how claimed customer savings would be verified.
The next verifiable developments are State rate decisions involving data-center costs and Publication of measurable compliance reports by pledge signers.
