    Florida-based renewable energy firm Spearmint Energy has broken ground on its new 150-MW/300-MWh battery energy storage project in West Texas.

    Called Revolution, the project is being built in partnership with Minnesota-based construction engineering company Mortenson. The two companies had entered into an engineering, procurement, and construction agreement for the project in November.

    Under the deal, Mortenson is responsible for designing and building the battery storage facility, substation, as well as the transmission line connecting the project to the Electric Reliability Council of Texas (ERCOT) grid.

    Spearmint says Revolution, which is expected to begin operation in mid-2023, will be one of the largest batteries in the US. Spearmint acquired the project from original developer Con Edison Development in a transaction announced in August.

    “Revolution will provide critical grid resiliency and reliability services to enable the continued deployment of low-cost renewable energy in ERCOT at a time when our nation is grappling with challenges brought by a changing climate, rising oil and natural gas prices, increasing demand for electricity, and the impacts of supply chain constraints, inflation, and tariffs on the construction of new generation facilities,” Andrew Waranch, Founder, President and CEO of Spearmint, said in a statement.

    Located in the wind and solar generation hub within the Lower Colorado River Authority’s transmission network, Revolution represents Mortenson’s 20th battery energy storage project. The EPC firm earlier was involved in construction of the Chisholm Grid battery storage project, also in Texas (see art at top). 

    Spearmint is a Florida-based next-generation renewable energy company enabling the clean energy revolution through battery energy storage.
