Mainstream Renewable Power has obtained environmental approval for its 264 MW Cerro Tigre wind farm in Chile.

The 80-turbine facility will be built close to the town of Antofagasta in northern Chile and will cost $630 million to build. Chile is a key market for Mainstream, which has over 2.2 GW of renewable energy capacity in development and 33 MW in operation in the country.

"This work will contribute to the development of a diversified, clean and reliable energy mix which will provide an efficient solution to the country and the people of this region," said Bart Doyle, CEO of Mainstream Renewable Power Chile. "We are a company that develops its own projects and we are always looking for new opportunities for solar and wind energy developments, and the Region of Antofagasta has important attributes that enable this."

Mainstream is preparing to start construction of two other wind farms in Chile this year – the 170 MW Sarco project in Atacama and the 129 MW Aurora wind farm in the region of Los Lagos.

These two wind farms will provide energy to Chile’s Central Interconnected System, while the Cerro Tigre wind farm will be connected to the northern grid.
