Spearmint Energy: Commissioning Activities Begin at Revolution Project


Spearmint Energy, a renewable energy company specializing in battery energy storage, has begun commissioning activities at Revolution, its 300 MWh battery energy storage project. Revolution will support a low-cost, clean and resilient grid for homes and businesses throughout the ERCOT power market.

The delivery and installation of the PowerTitan Series battery energy storage system supplied by the Sungrow Power Supply Co. Ltd., a global inverter and energy storage system solutions supplier, is a significant construction milestone for Revolution and brings Spearmint one step closer to commencing commercial operation of the project.

Located within a major wind and solar hub in the Lower Colorado River Authority’s transmission network, Revolution is expected to be one of the largest BESS projects in the United States. Sungrow’s PowerTitan liquid-cooled ESS product uses lithium iron phosphate battery cells and a liquid cooling system to more efficiently cool the BESS.

In December 2022, Spearmint broke ground on Revolution in partnership with Mortenson, a power engineering, procurement and construction contractor specializing in energy transmission and battery energy storage solutions. The project, which was energized in June 2023, reached mechanical completion in July and is scheduled to begin operations later this year.

“We are confident that with Sungrow’s support, Spearmint can help to further establish Texas’ grid as the gold standard for battery storage projects across the country,” says Andrew Waranch, founder, president and CEO of Spearmint. “We look forward to harnessing the capabilities of the PowerTitan platform as Revolution nears operation.”
