ARRA SGDP Detroit Edison (Advanced Implementation of Energy Storage Technologies)

DTE Energy demonstrated the use and benefits of Community Energy Storage (CES) systems to strengthen grid reliability and test the ability to integrate secondary-use electric vehicle (EV) batteries into the CES demonstration effort in their service territory at the Trinity Circuit. The performance data of the CES devices and control systems under in-service operating conditions was analyzed and used to identify gaps and facilitate how the devices can be standardized for use across the U.S. The project also integrates the utility-owned 500 kW solar system to the energy storage device; provides proof of concept testing for an integrated, centralized communication system; and tests the use of secondary-use Electric Vehicle (EV) batteries as CES devices.
