Spearmint Energy began construction of the Revolution battery energy storage system (BESS) facility in ERCOT territory in West Texas just over a year ago. The 150 MW, 300 MWh system is among the largest BESS projects in the U.S.
Spearmint broke ground in December 2022 on Revolution in partnership with Mortenson, the EPC on the project. Sungrow Power Supply provided the PowerTitan series to the project, which is located within a wind and solar hub in the Lower Colorado River Authority’s transmission network. The PowerTitan is a liquid cooled energy storage system that uses lithium iron phosphate battery cells and a liquid cooling system.
In October 2023, Spearmint announced the close of a $92 million tax equity investment by Greenprint Capital Management, marking what Spearmint reports 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.
During construction, Mortenson employed 34 team members and trade partners who, in approximately 42,000 working hours, installed 134 battery containers containing 6,432 battery modules, as well as 45 power conversion system units. Spearmint reports that revolution was completed on schedule, within budget and with a clean safety record.
“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.
Spearmint is also developing three additional BESS projects, known collectively as Nomadic. The three have a combined capacity of 900 MW / 2,000 MWh. The projects are located in Cooke, Galveston and Brazoria counties and were acquired in March of 2023. Spearmint anticipates that the first project within the portfolio will reach notice to proceed in early 2024 and begin commercial operation within 12 to 18 months.

300 MWh is perhaps big or even ‘huge’ for a battery storage but not generaly for storing energy. 300 MWh is about the energy that a typical nuclear power plant deliveres in 20 minutes.
A modern pumped hydro storage, for example (Nant-de-Drance, Switzerland), stores about 20 GWh (with turbines for 900 MW) what is about 67 times the 300 MWh.
Why are these lithium battery storage facilities continuing to catch on fire and explode? Killing everything in its path? They are installing these right next to schools and homes. It’s time to do some serious investigations and protect instead of destroy!!! These are evil people that are trying to destroy our country! Don’t let them install these in residential areas!!! Time to fight!
:I notice that every article about B/E/S/S/ facitlities are without an exact location.Is there a reason for this? You bet!. these are probably the most poisonous and and life threatening “green energy projects” on the planet. the local fire dept.s can’ put them out if lit. then the people , cattle land downwind are permanently poisoned. When I asked ESVOLTA about the regulations for putting in a B.E.S.S. UNIT they told me the local fire dept. was fully informed about the situation. AS a member of the local VFD we have received no training or special equipment to fight such a hazardous fire.They hung up on me.I live downwind of this monster they are going to build…. with promises of new inocme and jobs for the county.. Besides the child slave labor used to fuel this “life saving” “green energy. what else does this step into the future hold for us.?. permanent change of our environment? I thought we were tryin to avoid that… ?? or maybe just pay chemical companies to make us feel better?… I’m seeing green energy at it’s best…and it’s the same color as money..
