Microsoft Vows to Pay Its Own Way on Power for $117B Build

Microsoft Corp. said on Nov. 11 that it will power its data centers without government subsidies and without pushing costs onto other electricity customers, as it plans to build $117 billion of computing capacity this year, Bloomberg reported.

"We don't want other customers to be paying for our growth," Noelle Walsh, Microsoft's president of cloud operations and innovation, said at a BloombergNEF conference in Houston. "We will pay our own way." Bloomberg said the stance comes as data centers have become a political issue across the US, including in this month's midterm elections, which gave Democrats control of Congress.

A restated pledge, not a new contract

Walsh's remark extends what Microsoft calls its Community-First AI Infrastructure plan, which Brad Smith, Microsoft's vice chair and president, set out in a company blog post on Jan. 13. In that document Microsoft said it would ask utilities and public commissions to set its rates high enough to cover the electricity costs of its data centers, so that those costs are not passed on to residential customers. It also said it would work with utilities early to add generation and grid infrastructure when its sites need it, and would pay full local property taxes rather than seek reductions.

Microsoft's January post pointed to Wisconsin, where it backs a new rate structure that would charge "Very Large Customers", including data centers, the cost of the electricity needed to serve them.

Why it matters for the grid

The pledge puts the cost question in the rate case rather than in a federal rule. Utilities usually spread grid upgrades across their customer base, so a promise to pay is only as firm as the tariff a state commission approves. The new statement adds no megawatts, no tariff and no dollar figure for power, and Bloomberg's report gives none.

The $117 billion is Microsoft's total computing build for the year, according to Bloomberg, not a power budget. Voltgrid has tracked the spending side: Microsoft's quarterly additions to property and equipment reached $39.4 billion in the September quarter, as Voltgrid reported. The two figures are measured differently and should not be compared line by line.

Project Kilby: generation inside the fence

The clearest example of "paying its own way" in Bloomberg's report is a behind-the-meter data and power project in West Texas that Microsoft is working on with Chevron Corp. and the investment firm Engine No. 1. Behind the meter means the generation sits on the customer's side of the grid connection and serves the site directly.

The project, named Kilby, has been held up by Texas Governor Greg Abbott's moratorium on new data-center approvals, Bloomberg said. Abbott was defeated in the recent election by Democrat Gina Hinojosa, whose platform promises a potentially tougher stance on permitting. Chevron is still aiming to have Kilby running by 2028 and fully operational by 2031. Jeff Gustavson, Chevron's president of new energies, said a project that does not provide a net benefit to its communities is "doomed to fail."

Microsoft's supply deals point the same way: Constellation targets a 2027 restart of the 835 MW Crane Clean Energy Center under a 20-year Microsoft power purchase agreement, as Voltgrid reported.

What is not confirmed yet

Microsoft has not published a new statement, filing or tariff to accompany Walsh's remarks, and Bloomberg is the only full report of them that Voltgrid could read. No contracted-capacity figure for Microsoft's power supply has been confirmed: a headline on an aggregator site cites "7.9 GW contracted", but neither Bloomberg's text nor Microsoft's own January post gives that number, so Voltgrid does not use it. Kilby's capacity, ownership split and power sources were not stated in the report, and its schedule depends on how Texas permitting changes after the governor's defeat.
