RLC performed design and engineering services for a 25MW/38 MWH Massachusetts Battery Storage System project which employs Lithium Ion battery technology and an SMA Inverter System.

The Battery Storage system which is integrated within a custom-built building is capable of operating in parallel with an existing 22.8 kV electrical distribution system or as an islanded resource.

The BESS output is automatically controlled to support system events and limit loading on the distribution system.
