This project is designed to demonstrate a proof of concept for aggregated Community Energy Storage Devices in a utility territory. The project is comprised of the following major research objectives: 1) Installation of 20 Community Energy Storage (CES) devices across a utility territory; 2) The installation and use of centralized communication across the service territory; 3) The integration of a renewable resource with energy storage; 4) The creation of algorithms for dispatching CES devices for peak shaving and demand response; 5) The integration and testing of secondary-use electric vehicle batteries; and 6) The use of Energy storage devices to provide ancillary services to the power grid.

The CES systems will use a number of battery energy storage units utilizing lithium batteries with the required electronics and energy conditioning devices to locate backup power near to the customer. The energy storage system consist of 20 separate 25 kw (50 kWh) CES units and a 500 kW lithium battery storage device integrated with a PV solar module. At just under 1MW the CES units, coupled with the utility-scale PV and storage devices , will demonstrate peak shaving, demand response, voltage support, and emergency load relief; integration of renewable generation; and islanding during outages.
