At 180 MW, Upton 2 is Texas' largest operating solar facility. The Upton 2 plant consists of 718,000 photovoltaic solar panels. The lithium-ion energy storage project at Upton 2 will be the largest in Texas, and the seventh largest in the United States.
When completed in late 2018, the energy storage system, utilizing FlexGen's Hybrid OS software, will allow Vistra to store inexpensive solar energy generated during the day and deliver it to customers during evening hours when demand is greatest, improving grid reliability.
"Vistra is leading our country's transformation toward a reliable, low cost, sustainable energy mix and we're thrilled to be supporting its storage strategy," said Josh Prueher, FlexGen CEO.
"The power grid of the future will see energy storage integrated on site with solar, wind, and gas generation, and the Upton solar plus storage project is a trailblazing example."
