Consumers Energy Taps ESS Inc. Long Term Storage Solution for Solar Microgrid and Storage Project | New


WILSONVILLE, Oregon–(BUSINESS WIRE)–Nov. 10, 2022–

ESS inc. ( NYSE: GWH ), a leading manufacturer of long-life iron-flow batteries for commercial and utility-scale energy storage applications, has been selected by Consumers Energy, Michigan’s largest utility, to provide a battery system for a solar and storage microgrid. Consumers Energy will deploy ESS’s Energy Warehouse platform as part of a microgrid powering a gas compression facility in Michigan.

The project, which includes the first iron-flow battery to be used for a gas compression plant, underscores the capabilities of ESS’s energy warehouse to provide low-cost, long-duration energy storage over an operational life of more than 20 years. When combined with solar PV, the Energy Warehouse provides a durable and resilient energy storage solution for critical infrastructure.

Consumers Energy supplies natural gas and/or electricity to two-thirds of Michigan’s 10 million people and is CMS Energy’s principal subsidiary. This project will help achieve the goals set out in the Energy Storage Roadmap for Michigan, released in April by the Michigan Department of the Environment, Great Lakes and Energy, which calls for 1,000 megawatts (MW) of storage by 2025 and 4,000 MW by 2040. .

“ESS is proud to provide our safe, non-toxic battery storage system to a leading utility provider in the Midwest serving millions of customers,” said Hugh McDermott, senior vice president of business development and sales. at ESS Inc. “We are particularly pleased to have our first project for Consumers Energy will be a solar microgrid plus storage – a hugely beneficial solution for utilities and commercial/industrial customers who require sustainable energy resiliency solutions. and profitable.

“Consumers Energy’s partnership with ESS on this first-of-its-kind project is another positive step toward a cleaner energy future for Michigan,” said Dennis Dobbs, vice president of engineering and gas supply. at Consumers Energy. “This project meets our goal of generating and storing clean, renewable electricity to protect the environment, reduce electricity bills and increase the operational efficiency of the compressor station. And by integrating ESS’s energy warehouse, we are able to ensure the safe and reliable operation of our critical infrastructure.

Using iron, salt and water abundant in the earth for its electrolyte and simple materials for battery components, the ESS Energy Warehouse is a sustainable, environmentally friendly and sustainable storage solution. ideal for time-shifting renewables, managing a facility’s demand loads, and smoothing renewables intermittency on a constrained grid. It aligns well with the lifetime of solar and wind projects, supporting the low levelized cost of energy requirements for these applications.
