ESA To Deploy 150 MW Energy Storage System In Michigan After Permit Approval

ESA, a leader in clean energy innovation, has successfully obtained permits for the Salzburg Battery Storage Project, a 150 MW / 600 MWh standalone battery energy storage system (BESS) in Midland Township, Michigan. Situated on a 15-acre site in the northwest part of the township, the project is designed to deliver essential grid services such as peak shaving, load shifting, and regulation.

Unlike traditional peaker plants, the Salzburg system provides instantaneous response without ramp-up time, significantly improving efficiency and reducing emissions. As a standalone asset, it will feature a dedicated substation to directly connect to Michigan’s transmission system, ensuring seamless integration with the grid.

The Salzburg Battery Storage Project has a capacity of 150 MW / 600 MWh, sufficient to power approximately 30,000 homes for four hours, based on an average household’s energy consumption of 5 kW and 20 kWh per day. Unlike systems that rely on solar or wind facilities, this independent BESS is specifically engineered to provide critical grid services like energy arbitrage, black start capabilities, and enhanced reliability. By combining advanced technology with strategic design, the Salzburg Project represents a significant step forward in sustainable energy solutions for the region.

Lindsay Latre, Chief Executive Officer at ESA, mentioned “The Salzburg Project exemplifies our commitment to delivering innovative energy solutions that benefit local communities and strengthen the electric grid. This milestone is the culmination of years of work, showcasing our team’s ability to navigate rigorous state and local permitting processes. We are proud to lead the way in Michigan and lay the groundwork for future standalone energy systems in the region.”

The permitting process for the Salzburg Project involved close coordination between Midland Township, state regulators, and ESA’s public relations and entitlement teams. This collaboration led to the approval of the project, which is a first of its kind. The project highlights ESA’s role in driving sustainable energy solutions even in complex regulatory settings.

Currently, the project is part of the Midcontinent Independent System Operator (MISO) 2023 Study Cycle and is expected to complete the study process by 2026. The next steps include finishing the interconnection process, finalizing contracts for engineering, procurement, and construction (EPC), and obtaining financial approvals to proceed. Once operational, the Salzburg Project will be managed as a long-term asset for up to 30 years, after which it will undergo responsible decommissioning.
