Spearmint Energy has started commercial operation of a 150MW/300MWh battery energy storage system (BESS) in west Texas, US.
The Revolution BESS will provide grid services to the ERCOT market in Texas.
“We are proud to commence commercial operation at Revolution, our debut grid-scale storage project, to reliably deliver energy throughout ERCOT whenever and wherever it is needed,” said Spearmint Energy founder, president and chief executive Andrew Waranch.
“The project’s completion marks a major milestone for Spearmint as we cement our position as a leader in Texas’ fast-growing battery storage market.
“We are grateful to our many partners, including Mortenson and Sungrow, for their hard work and zero-injury mentality throughout the construction and commissioning process, and look forward to supporting Texas’ growing demand for electricity – particularly in the face of climate change and rising natural gas and oil prices – for years to come.”
Spearmint broke ground on Revolution in partnership with Mortenson.
The project reached mechanical completion following the delivery and installation of Sungrow’s PowerTitan Series battery energy storage system.
In October 2023, Spearmint announced the close of a $92m tax equity investment in Revolution provided by Greenprint Capital Management, marking one of the first applications of the Investment Tax Credit structure for a standalone battery energy storage system following the passing of the Inflation Reduction Act.
