The Macho Springs project, which First Solar bought last year from developer Element Power, was recently completed, and has begun selling electricity to El Paso Electric via a 20-year power purchase agreement.

Financial terms of the sale were not disclosed.

Macho Springs is the seventh utility-scale PV plant acquired since 2010, and the third from First Solar, by Southern Turner Renewable Energy LLC.

The JV combines Southern Power, a subsidiary of Atlanta-based electricity giant Southern Company, and Turner Renewable Energy, the private renewables business owned by US billionaire Ted Turner, an avowed environmentalist and among the largest private landowners in the US.
