In November 2022, Spearmint and Mortenson executed an EPC agreement under which Mortenson would design and build Revolution. Specifically, Mortenson would construct the battery storage facility, substation, and transmission line connecting the project to the ERCOT grid.
Revolution marks Mortenson’s 20th battery energy storage project.With a shared commitment to safety, a workforce of 34 Mortenson craft team members and trade partners contributed approximately 42,000 working hours to install 134 battery containers containing 6,432 Sungrow battery modules, as well as 45 power conversion system (PCS) units, at Revolution. Revolution was completed on schedule, within budget, and 100% injury-free.
“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. 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,” said Andrew Waranch, Founder, President, and Chief Executive Officer of Spearmint Energy.
“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, Spearmint announced the close of a $92 million 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.
