ESS Lewes Project LLC on Oct. 3 filed with FERC both a notice of exempt wholesale generator status and an application for market-based rate authority for an energy storage project.
The company is a subsidiary of Alevo USA Inc., which is part of Alevo Group SA, a Swiss maker and developer of battery energy storage systems and projects.
ESS Lewes is developing an 8-MW/4-MWh energy storage project in Lewes, Delaware. This will be the first commercial deployment of a new Alevo battery technology. The project will sell capacity, energy and ancillary services in the PJM Interconnection market. It will interconnect with the Lewes Board of Public Works transmission system, which interconnects with Delmarva Power and Light.
The current plan is for the project to have 88 lithium-ion battery storage racks housed within a retired generator building.
