Texas IPP Vistra Energy has contracted energy storage integrator FlexGen to install a 10MW / 42MWh energy storage system (ESS) at the 180MW Upton 2 Solar Power Plant in Texas.   

The lithium-ion storage system, which uses FlexGen’s Hybrid OS software, will be completed in late 2018. It will be the largest storage project in Texas and the seventh largest in the US.

“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.”

FlexGen is backed by Altira Group, General Electric (GE) and Caterpillar. Its storage system will be used to store solar power generated during the day and deliver it to customers during evening hours when demand is greatest, improving grid reliability.
