- Microsoft pledged to "pay its own way" for electricity as its data center footprint grows.
- President Trump endorsed the plan in a post on Truth Social.
- Other Big Tech companies are likely to follow suit.
Microsoft is promising to cover the costs of electricity needed to power its rapidly growing fleet of data centers in suburban and rural communities across the US.
In a speech on Tuesday, Brad Smith, the president and vice chair of the Big Tech giant, said that going forward, Microsoft will "pay utility rates that are high enough to cover our electricity costs."
It's a bold pledge to make at a time when AI is fueling a historic surge in demand for power in the US, and electric bills are surging for the average American utility customer.
It is also one that state regulators have heard before as utilities, their data center customers, and consumer advocates argue over who will bear the cost of new infrastructure needed to serve AI's enormous appetite for power.
But as the impact of data centers on electricity rates becomes an increasingly hot political flashpoint, Microsoft may have no other choice but to follow through, and the rest of Big Tech might not be far behind.
"There is no free lunch for tech players, and Trump is watching," said Dan Ives, global head of tech research at Wedbush Securities.
Ives expects other Big Tech companies to follow Microsoft's lead and make similar pledges addressing local concerns around major data center buildouts sooner rather than later.
Trump is indeed watching.
"I never want Americans to pay higher Electricity bills because of Data Centers," President Trump wrote Monday night in a post on Truth Social.
The "big technology companies who build them," the president said, "must pay their own way."
Trump wrote that his administration had collaborated with Microsoft on the company's pledge to cover its electricity costs, and alluded to future announcements by other companies.
"More to come soon!" he wrote.
When asked for further comment, the White House Press Office pointed to President Trump's post on Truth Social.
Microsoft's four-part plan to ensure it is paying its fair share of electricity costs was laid out in a blog post this week. The plan consists of asking utilities and regulators to set their rates high enough to cover their data center costs, collaborating with utilities to cover the costs of new infrastructure, looking for ways to operate data centers more efficiently, and advocating for affordable, reliable power at the state and federal levels.
When asked for further comment, a spokesperson for Microsoft pointed to the company's blog post.
Consumer advocates are cautiously optimistic about Microsoft's promise to pay its fair share, but eager to see more details — especially from the utilities that serve the data centers.
"These are only rough concepts that don't get at the root of the problem, which is the scale and speed at which the industry is moving," said Julie Bolthouse, director of land use at Virginia's Piedmont Environmental Council.
Dominion Energy, Virginia's largest public utility, has said it is in contract talks with data center customers for 47 gigawatts of new demand — double Dominion's current peak load.
Bolthouse is concerned about the legitimacy of that demand — and who might end up footing the bill if it never comes to fruition.
"The current process of unreviewed contracts between utilities and data centers has broken the planning process and threatens the reliability of the system," said Bolthouse.
Charles Hua, founder and director of Powerlines, a nonprofit that advocates for utility regulation reform, said that data centers can be "good grid citizens" if local utilities prioritize investment in grid-enhancing technologies and energy efficiency over building new power plants.
"Doing so will require states to reimagine our outdated system of utility regulation and make necessary changes to center consumers going forward," he said.
