Florida-based renewables developer Spearmint Energy has begun commissioning its 150MW/300 megawatt-hour battery energy storage system (BESS), known as Revolution, which has two hours of backup and is located in Texas.

The PowerTitan Series battery system is being supplied and installed by Chinese solar inverter and energy storage systems supplier Sungrow.

This will take the project another step towards the launch of commercial operations.

Revolution is one of the largest BESS projects in the US, located in the Lower Colorado River Authority’s transmission network.

Sungrow’s PowerTitan liquid-cooled battery system leverages lithium-iron phosphate battery cells and a liquid cooling system for heat dissipation.

It will enable Spearmint to support a low-cost, clean and resilient grid for homes and businesses across the Electric Reliability Council of Texas power market.

Spearmint Energy founder, president and CEO Andrew Waranch stated: “We are pleased to partner with Sungrow, well-recognised for its state-of-the-art projects and expertise in innovative and scalable energy storage solutions, on our inaugural project.

“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. We look forward to harnessing the capabilities of the PowerTitan platform as Revolution nears operation.”

Ground-breaking on the project took place in December 2022. The engineering, procurement and construction contract was awarded to Mortenson, a Minnesota-based construction services provider.

Revolution was energised in June 2023 and is scheduled to begin operations later in the same year. It will provide resilience to the Texas grid during times of extreme weather.
