Facebook will purchase the output from 139MW of the 200MW Headwaters II project in Randolph county, Indiana. The deal will last 15 years.
Mark Zuckerberg’s company is looking to power its global operations with renewables.
In March, Facebook announced a deal with Enel to source some of the power from the 320MW Rattlesnake Creek site in Nebraska.
It also has power deals in Texas and Iowa, as well as some in Europe.
Joao Manso Neto, EDP Renewables CEO, said: "Corporate purchasers, like Facebook, who purchase fixed, competitively-priced renewable energy, have greatly contributed to the continued growth and success of the wind industry."
Elsewhere in the US, food and beverage producer JM Smucker has also signed a power purchase agreement with developer Lincoln Clean Energy.
From 2020, jam-producer Smucker will buy output from 60MW of LCE’s 230MW Plum Creek in Nebraska.
The power will cover roughly 50% of Smucker’s electricity use, the company said.
Smucker also owns a number of well-known food and drink brands in the US, including Folgers and Dunking Donuts.
