The New Technology Implementation Grant program is a part of the Texas Emissions Reduction Plan.
The battery system will be located on the site of Luminant’s 180-megawatt Upton 2 Solar Power Plant, Texas’ largest operating solar facility. The batteries will capture excess solar energy produced during the day and release the energy in the late afternoon and early evening when demand is highest.
Once complete, the 10-MW/42-MWh lithium-ion energy storage system at Upton 2 will be the largest in Texas and the seventh-largest in the United States.
The company expects the project to be operational in late 2018. Upton 2 Solar Power Plant is located near McCamey in Upton County, Texas.
