en.Wedoany.com Reported - e-STORAGE, the energy storage solutions business of Canadian Solar Inc., will supply a 75 MW / 381 MWh DC battery energy storage system (BESS) to Apex Clean Energy, to be deployed in Branch County, Michigan, co-located with Apex's operational Coldwater Solar project.

Under the agreement, e-STORAGE will provide a complete integrated solution, combining SolBank 3.0 battery modules, power conversion systems, and e-STORAGE's proprietary EQ-S energy management system into a unified utility-scale platform. Delivery is expected to begin in early 2027, with commercial operation targeted for mid-2027. e-STORAGE will supply its proprietary SolBank battery packs, which utilize lithium iron phosphate (LFP) cells, all manufactured at Canadian Solar's own facilities, providing customers with full supply chain visibility and compliance.

The Coldwater Storage project advances under a clear policy framework: Michigan law requires utilities to bring 2,500 MW of energy storage capacity online by 2030; the state's largest coal-fired unit is scheduled to retire by 2032, removing dispatchable capacity from the MISO (Midcontinent Independent System Operator) grid, which storage must replace. Once operational, the project will store low-cost electricity and discharge it during peak demand periods, helping stabilize power supply as Michigan transitions to solar and wind energy.

Apex CEO Ken Young stated that rapidly growing electricity demand requires storage projects like Coldwater to help the grid meet this trend, and e-STORAGE has the technology and scale to deliver the project, expressing pleasure in collaborating with Canadian Solar again.

e-STORAGE President Jeff Roy noted that Michigan is rebuilding its generation structure on a fixed timeline, and this partnership demonstrates how to translate that goal into actual reliable capacity. By providing batteries, power conversion systems, and the EQ-S control system as an integrated solution, e-STORAGE serves as Apex's single-point technical partner throughout the project's lifecycle.
