Facebook will purchase the output from a 38% share of the 525MW Aviator Wind project in Coke Country, central Texas.
The project is being developed in partnership between Apex Clean Energy and funds managed by Ares Infrastructure and Power. It is due online in 2020.
The power from 199.76MW of the project will be used by Facebook to power its operations in the region.
"The ambitious sustainability goals of corporate leaders like Facebook will play a key role in accelerating the transition to renewable energy — faster than ever anticipated — in the years to come," said Mark Goodwin, CEO of Apex Clean Energy.
Apex said it will announce another corporate buyer for the majority of the balance of Aviator Wind "at a later date".
Facebook is one of the largest buyers of wind power in the US. According to Wood Mackenzie Power and Renewables, the social media goliath signed 2.2GW of power deals in 2018.
It has power deals with projects in Nebraska, Indiana, Texas and Iowa, as well as some in Europe.
