Trump’s AI Electricity Pledge Expands Beyond Big Tech

A voluntary White House pledge that artificial intelligence’s power demands will not raise household electricity bills has grown far beyond the seven technology companies that first signed it. A White House list of signatories obtained by the Wall Street Journal shows nearly 200 entities — electric utilities, data center developers, and others — have now committed to the Ratepayer Protection Pledge, pulling in the companies and officials who actually generate, sell, and price the electricity AI consumes.

That widening is the substance of the news. When President Donald Trump unveiled the pledge on March 4, 2026 it bound Amazon (AMZN ), Google, Meta, Microsoft (MSFT ), OpenAI, Oracle (ORCL ), and xAI to cover the cost of the generation and grid upgrades their data centers require rather than pass those costs to existing customers. Hyperscalers, though, do not set retail rates. Utilities and state regulators do — which is why the expanded roster matters more than the original one.

Who signed, and what they promised

The signatories the Journal identified include utility majors NextEra Energy (NEE ) and Duke Energy (DUK ) alongside data center landlords Equinix (EQIX ) and Digital Realty — firms on the supply side of the market the first version of the pledge could not reach. Earlier in the month, Republican governors Greg Gianforte of Montana, Mark Gordon of Wyoming, and Mike Kehoe of Missouri also signed on, POLITICO reported. Governors are consequential here because they appoint or oversee the commissions that approve electricity rate increases.

The commitments themselves are unchanged. Signatories agree to build, bring, or buy the new power their facilities need, pay for the delivery-infrastructure upgrades those facilities trigger, negotiate separate rate structures with utilities and states, and hire from local communities. The load-bearing clause is a promise to pay for contracted power “whether they use the electricity or not” — the provision meant to stop households from absorbing the cost of capacity a data center reserves and then leaves idle. Federal forecasts expect data center electricity use to double or more this decade, and in regions already crowded with them, wholesale power costs have surged.

A commitment, not a rule

The reach is new; the legal force is not. Trump first previewed the idea in his February 2026 State of the Union address, and a presidential proclamation later declared that the pledge’s commitments “effectuate the national policy of the United States.” That is formal language, but the pledge stays voluntary: it carries no penalties, no audit requirement, and directs no agency to write binding rules.

Enforcement is the gap the expansion does not close. Retail electricity prices are set by state public utility commissions, not the White House, and the Journal noted the effort could prove hard to enforce for that reason. The Brookings Institution has argued that the pledge will not protect anyone until state legislatures and regulators write its commitments into the tariffs that govern what large customers actually pay. The Energy Department says it is working with the White House to implement the pledge, but its levers are federal grid-reliability and interconnection rules, not the retail rates that show up on a monthly bill.

Why Washington keeps widening the tent

The push comes as electricity affordability hardens into a midterm issue. Power prices have climbed faster than overall inflation over the past year, and local opposition to data center siting has spread — a fight New York turned into a land-use battle, and one reason developers are increasingly building their own generation to sidestep the grid entirely as AI demand collides with strained transmission.

States are not waiting for Washington. Virginia, Ohio, and Oregon have already created separate rate classes that require large-load data centers to carry their own infrastructure costs, and a bipartisan bill in Congress would write the pledge’s terms into federal law — though authority over retail rates would still rest with the states. The administration has paired the pledge with a broader energy-and-AI agenda that leans on new gas and nuclear generation, an approach that has drawn scrutiny over the energy security underpinning it.

For all the new signatures, the test is unchanged. Whether any of this reaches a household’s bill will be decided in rate cases before state commissioners bound by none of it — which is why the White House keeps trying to enlist the people who are.
