Energy storage project developer EnerSmart will use zinc-based battery systems from Eos for upcoming stand-alone projects in California. Eos will provide at least 90 MWh, and as much as 180 MWh, of energy storage to EnerSmart over the next two years.
The projects are planned to be powered by Eos’s Znyth battery technology to provide improved grid stability and increased renewables utilization across multiple locations in California. The first project, anticipated to supply 9 MWh of storage in El Cajon to CAISO (California’s independent grid operator), is valued at $2 million with installation scheduled for the fourth quarter of 2021.
“We are very excited and believe that this agreement will expand our installed base and continue to show the demand for longer duration storage. We look forward to working with EnerSmart to bring innovative technology designed to make a long-term positive impact on California’s power grid,” said Balki Iyer, Chief Commercial Officer of Eos.
The Eos Znyth battery is designed to provide continuous power upon installation and is anticipated to have a useful life of 20 years. This storage solution developed in Edison, New Jersey, is proven to be safe across a wide range of operating conditions and will be shipped from Eos’s manufacturing facility located in Pittsburgh, Pennsylvania.
“As we expand our portfolio of utility scale energy projects in key markets, we rely on technology that can provide safe, reliable storage at an attractive cost,” said Marc La Magna, Co-founder and Managing Partner at EnerSmart. “Eos Energy’s technology is designed to address these areas and importantly, they share our passion and optimism that energy storage and renewable energy projects will continue to be widely adopted in California and around the country.”

You can see by the pictures the energy density of these projects is low. Compare the TESLA Megapack with this system and you can see the difference in foot print. But, that being said, this technology is a 20 year technology, it is modular enough to change out chemistry on the fly and is supposed to be a 20 year in use technology. Over all life costs for this technology should be lower than battery packs now being sold. Some of these very large solar PV or wind farms have plenty of real estate available for redox flow or Zinc type chemistries that can last 20 years of service and beyond. The unknowns, overall cost, O&M costs for 20 years. These types may be perfect for Regional energy storage facilities where a thousand acre facility may be fed by many transmission regions could be served by one giga-watts storage system. Nodal regional energy storage and the ability to grab energy from one grid transmission feeder and store it for later use, while taking some already stored energy and switching it into another transmission grid for a day ahead market operation. Energy ‘shuttling’ could become a very big revenue stream that would replace the old fueled capacity market. The electric industry has to dump the concept of fueled generation in spinning reserve operation and exchange this for giga-scale energy storage with inverter switching outputs to service the grid demands with flexible energy storage instead of peaker plants.
