Mainstream Renewable Power Ltd., a closely held Irish clean-energy developer, is seeking environmental permits to develop a $240 million wind farm in Chile’s southern Bio Bio region.

The Alena wind project will include as many as 43 turbines with a total capacity of 107.5 megawatts, Dublin-based Mainstream said today in a filing with environmental licensing agency Servicio de Evaluacion Ambiental. The project includes 21.4 kilometers (13.3 miles) of power lines and a substation.

Work on the wind farm is expected to start Nov. 30, according to the filing.
