Environmental green light for 222.6MW wind farm

The Llanos del Viento wind farm will serve the annual energy needs of 168,000 homes when it enters operation

Mainstream Chile’s Llanos del Viento wind farm has received its Environmental Qualification Resolution (RCA) from the Antofagasta region’s Environmental Evaluation Service.

The project, which involves an investment of US$400million, will have a total of 42 wind turbines with an installed capacity of 222.6 MW, which equates to the annual energy consumption of around 168,000 homes.

The project is located 34km to the east of the city of Antofagasta, and will be connected to the National Electric System by the O’Higgins Electric Substation via a 220kV high voltage line. 

Manuel Tagle, General Manager for Mainstream LATAM, welcomed the latest progress, which comes only a week after the environmental authority in the Atacama region granted approval for the company’s Valle Escondido solar PV project.

He said: “This news represents a new milestone for the projects we are developing in Chile, positioning Mainstream as the largest renewable energy developer in the country that is contributing to the decarbonisation of the national energy matrix.”

The Llanos del Viento wind farm is the fifth of Mainstream’s projects in the Antofagasta region to obtain its RCA. Environmental approval had previously been granted for the Cerro Tigre, Tchamma and Ckani projects, and in March the company obtained environmental approval for its Pampa Tigre solar PV project.

Together, these projects will add up to a total of 800 MW of clean energy in a region that is rich in sources of non-conventional renewable energy, but that currently has the highest number of thermal power plants in operation.
