DALLAS, Sept. 8, 2015 /PRNewswire/ -- Continuing its commitment to serve customers and Texas with a balanced energy portfolio, Luminant has agreed to buy 116 megawatts generated by a SunEdison large-scale solar plant in Upton County, Texas. The power purchase agreement, which is being added to Luminant's already diverse mix of energy sources, is the largest in the nation for a merchant generator operating in a competitive market.

In announcing the long term solar agreement, Luminant Chief Executive Officer Mac McFarland said, "We have a long history of operational excellence and innovation in providing safe, affordable electricity for the benefit of Texans, and we are proud to continue that tradition with this solar project."

Luminant, the largest power generator in Texas, now adds solar to its diverse energy mix, which includes coal, natural gas and nuclear power, as well as significant purchases of wind-generated electricity.

Starting in late 2016, Luminant will purchase power from SunEdison's Castle Gap facility, a photovoltaic solar plant currently under development in Upton County. Unlike typical agreements in which the solar-generated power is sold to a specific customer or in a regulated portion of Texas, Luminant will sell the electricity to the ERCOT competitive market.

"As we evaluate our future generation needs, we focus on projects that are profitable and able to compete in the wholesale market. This agreement with SunEdison meets those goals since solar generation costs have become increasingly competitive," McFarland added.

SunEdison is the world's largest renewable energy development company delivering predictably priced electricity to residential, commercial, government and utility customers. For competitive reasons, prices are not being disclosed.
