The deal is part of JERA's effort to expand its global renewable energy capacity to 5 gigawatts (GW) by March 2026 and is the company's first U.S. renewable project.
The construction of the wind farm in Willacy County in Texas will begin in early 2022 with operation scheduled to start in the last quarter of the year, JERA said in a statement.
Including the new U.S. project, the Japanese company has 1.75 GW of renewables assets.
JERA, a thermal power and fuel joint venture between Tokyo Electric Power Company Holdings and Chubu Electric Power, aims to increase its renewables assets in the United States to 2 GW by taking an advantage of the government's support for the development of renewable energy.
"The U.S. renewable energy projects currently under our consideration amount to more than 4 GW and we want to select and develop 2 GW of promising projects of that," JERA President Satoshi Onoda told reporters last week.
