ESS, a manufacturer of long-duration iron flow energy storage, was chosen to deploy a battery-powered microgrid for a Michigan public utility.
Consumers Energy, Michigan’s largest energy provider, is planning a solar and storage microgrid and will deploy ESS’s Energy Warehouse platform to help power a gas compression facility.
ESS said including an iron flow battery for a gas compression plant is an industry first. It will be paired with solar photovoltaics and provide a sustainable, resilient energy storage solution for critical infrastructure.
Consumers Energy provides natural gas and/or electricity to two thirds of Michigan’s 10 million residents. It is the principal subsidiary of CMS Energy.
Michigan’s energy storage roadmap, released in April, calls for 1,000MW/4,000MWh of storage by 2025 and 4,000MW/ 16,000MWh by 2040.
ESS said its battery technology uses iron, salt and water for the electrolyte, and simple materials for battery components.
