CHARLOTTE, N.C. – May 12, 2022LS Energy Solutions (“LS-ES”), a leading provider of grid-connected energy storage solutions, announces its contract with cleantech integrator Ameresco to supply an AiON-ESSTM energy storage system for a 6MW/6MWh project in Fort Detrick, Maryland. The project will supplement an existing 18MW solar facility and is expected to be operational in early 2023.

During the project’s 20-year operating life, the AiON-ESS units will help the Fort Detrick Army Garrison lower its total electricity spend. This will be achieved by participating in frequency regulation, demand response, and energy supply markets within PJM, the world’s largest wholesale electricity market. The storage system will be microgrid-ready to support Army’s resiliency goals at the Garrison in the future.


The project proves the all-around capabilities of LS-ES to meet customer needs with its flexible AiON-ESS platform. LS-ES will also support the project with warranties and replacement services for the AiON-ESS systems to ensure economic optimization throughout the project’s lifetime.


“We are honored to work with Ameresco to reduce utility costs and enhance the energy infrastructure at the Ft. Detrick Army Garrison,” commented Steve Fludder, CEO of LS Energy Solutions.  “Our AiON-ESS provides all AC and DC energy storage functions in a single, easy to install and commission unit.  We look forward to deploying more of these systems with Ameresco in similarly critical applications.”

“We’re thrilled to be working with LS Energy Solutions to provide a dependable, all-in-one energy storage solution for Fort Detrick.” said Tony Colonnese, VP of Energy Security Solutions at Ameresco.
