Leading manufacturer of long-duration iron flow batteries for commercial and utility-scale energy storage projects, ESS (NYSE: GWH), announced it will supply its flagship Energy Warehouse battery platform to a solar plus storage microgrid by Consumers Energy, Michigan's largest energy provider.
The ESS Energy Warehouse utilizes earth-abundant and environmentally-safe materials for its electrolyte and components. It provides a durable and long-lasting storage solution for time-shifting renewables, optimizing a facility's demand charges and smoothing the intermittency of renewables on a constrained grid.
The first iron flow battery storage system for this microgrid project, capable of providing up to 12 hours of flexible energy capacity—the Energy Warehouse will provide service over the expected 20+ year operational lifespan, aligning well with the lifespan of the project's solar generation unit.
"ESS is proud to provide our safe and non-toxic battery storage system to a leading utility provider in the Midwest serving millions of customers," said Hugh McDermott, SVP of business development and sales at ESS.
This solar plus storage microgrid will power a gas compression facility in Michigan. It helps deliver on Consumers Energy's goal of "producing and storing clean, renewable electricity to help the environment, reduce electric bills and increase operational efficiency," commented Dennis Dobbs, VP of gas engineering and supply at Consumers Energy. Additionally, it will help to achieve the goals laid out in the Energy Storage Roadmap for Michigan, released by the Michigan Department of Environment, Great Lakes and Energy (EGLE), calling for 1,000 MW of storage by 2025 and 4,000 MW by 2040.
