Luminant has agreed to buy 116 MW generated by a SunEdison large-scale solar power 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 power agreement, Luminant CEO 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."
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.
For competitive reasons, prices are not being disclosed.
On sunny days, these 116 MWs are enough to power 58,000 Texas homes during normal demand and 23,200 homes during peak demand.
The Castle Gap facility will span nearly 800 acres in West Texas.
About 485,000 photovoltaic solar panels will be installed at the facility.
