Project Overview
Located in West Texas, the Revolution Energy Storage Project was delivered by Mortenson under a full engineering, procurement, and construction (EPC) contract for Spearmint Energy.
The project included a 150 MW/300 MWh battery energy storage facility, substation, and transmission line connecting the project to the Electric Reliability Council of Texas (ERCOT) grid.
Customer Impact
Spearmint Energy required utility-scale battery storage and grid interconnection infrastructure capable of supporting participation in the ERCOT market. Mortenson delivered the battery energy storage facility, substation, and transmission infrastructure required for commercial operation under a single EPC contract.
In addition to constructing the project, Mortenson supported Inflation Reduction Act (IRA) compliance efforts. Following project development, Spearmint Energy secured a $92 million tax equity investment through an Investment Tax Credit structure for the standalone battery energy storage system.
