Google, Microsoft, Meta, Amazon and several artificial intelligence companies signed a pledge at the White House on Wednesday to bear the cost of new electricity generation to power their datacenters.

The agreement is meant to help mitigate concerns that big tech’s datacenters are driving up US electricity costs for homes and small businesses at a time the administration of Donald Trump is seeking to curb inflation.

“This means that the tech companies and the datacenters will be able to get the electricity they need, all without driving up electricity costs for consumers,” the president said at the pledge signing event. “This is a historic win for countless American families and we’ll also make our electricity grid stronger and more resilient than ever before.”

The so-called “Ratepayer Protection Pledge” was first announced by Trump in his State of the Union address, and comes as communities and state legislators increase scrutiny of rapidly proliferating datacenters.

Datacenters consume vast amounts of electricity to run server racks and cooling systems for the development of technologies such as artificial intelligence.

“Some datacenters were rejected by communities for that, and now I think it’s going to be just the opposite,” Trump said, referencing cancelled or postponed projects in recent months across several states after local opposition.

The pledge includes a commitment by technology companies to bring or buy electricity supplies for their datacenters, either from new power plants or existing plants with expanded output capacity. It also includes commitments from big tech to pay for upgrades to power delivery systems and to enter special electricity rate agreements with utilities.

The effort is aimed at drawing support from towns and cities that otherwise oppose the projects, said the Trump official, who spoke on the condition of anonymity.

“There will be no new datacenter development that’s going to happen without the local communities reading and understanding what this pledge is,” the official said.

Oracle, xAI and OpenAI were also in attendance to sign the pledge.

The initiative is being launched ahead of the November midterm elections, with voters increasingly concerned about energy affordability and the increased strain on the country’s power grids from datacenters.

Companies represented at the White House include some of the biggest names in the tech sector, which are investing billions in new AI computing capacity that draws vast amounts of electricity.

Trump has urged those firms to build or secure dedicated power capacity to meet demand rather than relying solely on regional grids, part of a broader effort to balance technological competitiveness with political and economic concerns about energy costs.

It’s not clear, however, that the effort will get new supplies of electricity built quickly enough to ease pressure on grids, said Jon Gordon, who is a senior director at Advanced Energy United, a clean energy trade group that includes some datacenters.

That’s in part due to Trump’s policy focus on increasing natural gas and other fossil fuel-fired power for datacenters, instead of quicker-build sources like solar and wind, he added.

“The real problem is the inability to get generation online fast enough to meet the datacenter demand,” Gordon said. “Hyperscalers paying for the generation doesn’t get it online any faster.“

Advocates and critics alike will be watching closely to see whether the pledge produces concrete commitments or remains largely symbolic, as lawmakers and consumer groups have called for stronger protections to prevent utility bill increases tied to datacenter build-outs.
