ESS operated by Consumers Energy for Michigan microgrid battery deployment – ​​pv magazine USA

Microgrid helps utility meet goals set out in Michigan Department of Environment’s Energy Storage Roadmap to drive installation of 1 GW of energy storage projects by 2025 and 4 GW by 2040.

Energy Storage Systems Inc. (ESS), a manufacturer of iron-flow batteries, has been retained by the Michigan utility Consumers Energy to supply batteries to a solar energy storage microgrid project plus powering a facility gas compression.

Consumers Energy will deploy the company’s Energy Warehouse solution to deliver a 20+ year old energy system. The project aims to help the utility achieve the goals outlined in the Michigan Department of the Environment’s Energy Storage Roadmap, which aims to see the installation of 1 GW of energy storage projects in by 2025 and 4 GW by 2040.

Using abundant iron, salt and water resources in its electrolyte, the ESS Energy Warehouse is an environmentally friendly long-term storage solution suitable for day-to-day time-shifted renewable energy. In this case, the Energy Warehouse manages the daily demand loads of the gas compression plant and balances the renewable energy intermittency on a constrained grid.

“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.

In a recent interview with pv magazine United States At the RE+ conference, McDermott said the long-duration energy storage market is ripe to expand its manufacturing base in various markets such as Florida, North Carolina, Virginia and California.

In the United States, ESS is looking to expand production to 25 MW per year by the end of 2022 and over 100 MW by the end of 2023, while the company also scales to produce 400 MW per year in Australia.

ESS aspires to produce 750MW per year, which was mentioned during the company’s Q2 22 earnings call. The company sees demand reaching well over 1 GW per year of manufacturing capacity. The Long Duration Energy Storage Council released a report suggesting that under the right conditions, 1.5-2 TW/85-140 TWh long life batteries could be deployed by 2040.

Consumers Energy’s parent company, CMS Energy, released a ESG and Sustainable Development Report 2022 following a 2021 IRP that calls for a 60% reduction in CO2 emissions from its utility service territory by 2025, including the retirement of its 1.88GW coal generation fleet from by 2025 and installing 8 GW of new solar capacity by 2040 to drive $650 million in savings for customers for ratepayers. During this period, the utility’s generation mix will change from its current mix of 39% natural gas, 19% coal generation, 11% renewable energy and 8% nuclear energy to a generation mix of electricity consisting of 63% renewable energy, 12% energy storage, 10% natural gas and 15% customer savings programs.
