Regarding power supplies, the administration projected that private energy generation efforts by data developers would generate excess capacity for local communities.
"Electricity bills for American families will actually come down," Trump said.
He added that surplus energy produced by facilities would be redirected back into regional power grids.
"They're going to have a lot of electricity left over, and they'll put that into the grid," he said.

In a social media statement prior to the event, Trump referenced local economic outcomes and commented on opposition measures taken in northeastern states, calling them a "terrible decision."
White House representatives framed the expanded commitment as a dual strategy for domestic economic health and global technological competitiveness.
"President Trump is expanding the Ratepayer Protection Pledge to governors, legislators, developers, and power providers to ensure everyone involved in building and powering data centers covers their own costs instead of passing them on to American families," said White House spokeswoman Taylor Rogers.
She stressed the administration's intention to leverage the infrastructure expansion for national innovation.
"The President's bold action is turning data centers into engines of growth for local communities, while cementing America's dominance in the global AI race," Rogers said.
Despite the pledge, regional and political opposition to data centers has mounted across multiple states, where critics cite environmental impact, land use, and potential price hikes.
Projections by technology consulting firm ICF indicate that surging electricity demand could drive monthly consumer utility bills up by 15% to 40% by 2030.
