Powering Tomorrow — Today
On Dec. 31, 2018, Luminant announced that its Upton 2 battery energy storage system project had finished construction and began operating.
The battery system, which is the largest energy storage project in Texas and seventh largest in the United States, is located on the site of Luminant’s 180-megawatt Upton 2 Solar Power Plant in Upton County, Texas. The solar facility continues to deliver on the company’s strategic plan to strengthen and expand its integrated businesses through enhanced retail solar offerings and diversity across its generation fleet. It is also direct evidence that competitive generators will invest in batteries in Texas when supported by market economics.
The 10-MW/42-MWh lithium-ion energy storage system captures excess solar energy produced at Upton 2 during the day and can release the power in late afternoon and early evening, when energy demand in ERCOT is highest. The battery system can also take advantage of low-priced grid power — during times of high wind output, for example — to charge the batteries to be available for higher demand periods.
Vistra is also currently developing the world’s largest battery energy storage project, the 300-MW/1,200-MWh storage system at its Moss Landing Power Plant in California, scheduled for commercial operations in the fourth quarter of 2020.
Harnessing New Potential
Leading By Innovation
Luminant is excited for this opportunity to work with PG&E, and the State of California, to develop a world-class battery project on its Moss Landing site, while building industry-leading expertise in the development and commercialization of battery storage assets. The Moss Landing battery project will be the largest of its kind in the world, and it exemplifies Luminant’s vision for new technologies that support of the changing energy supply landscape.
