Microsoft will buy more than 10.5 GW of clean energy projects from Brookfield Asset Management and its Brookfield Renewable affiliate to help the technology company run its data centers and other operations on carbon-free power all the time, the companies said Wednesday.

“This first of its kind agreement, which is almost eight times larger than the largest single corporate [power purchase agreement] ever signed, is a testament to our ability to reliably deliver clean power solutions at scale to our corporate partners and accelerate the energy transition,” Connor Teskey, CEO of Brookfield Renewable and president of Brookfield Asset Management, said in a news release.

Between 2026 and 2030, Brookfield will deliver wind, solar and “new or impactful carbon free energy generation technologies” to Microsoft in the United States and Europe. The agreement between the companies could expand in size and to locations outside the U.S. and Europe, they said.

Microsoft had previously contracted for about 1 GW of clean power from Toronto, Canada-based Brookfield, the companies said.

Across its global operations Microsoft had contracted for more than 13.5 GW of clean energy in 16 countries as of the end of 2022, according to its most recent sustainability report.

U.S. corporations entered into deals for 12.9 GW of clean power in 2023 and have at least 38 GW of operating projects, the Clean Energy Buyers Association said in its most recent Deal Tracker report.

Brookfield owns about 33 GW, and its project development pipeline totals about 155.4 GW, according to the company.
