On March 16, ComEd announced a community energy storage pilot project to test the use of battery storage technology to reduce the impact of power outages in residential areas where customers experience service interruptions, particularly in extreme weather events. ComEd noted the project will use the PureWave Community Energy Storage system from S&C Electric Company, featuring a 25-kWh lithium-ion battery.

According to ComEd, its CES pilot is being conducted in Beecher, Ill., approximately 40 miles south of Chicago, and will focus on improving power reliability. In the event of a power outage, ComEd intends the energy storage system to automatically restore power with enough capacity to supply power to a group of customers for the duration of most typical outages.

Michelle Blaise, senior vice president, Technical Services, ComEd remarked:

Through grid modernization and smart grid investments, our reliability performance has been best on record for five years running, and we’re committed to continuous improvement. We want all ComEd customers to experience great reliability and that’s why we’re innovating and piloting emerging technologies such as energy storage to bring new value to communities and help improve service for our customers. We’re excited about the potential that battery storage offers to minimize the impact of a power outage while we continue to make progress in preventing them.

Blaise said that additional CES pilots are planned for the ComEd service territory. ComEd is also exploring the potential of energy storage to support the integration of renewable energy sources. The company received a $4 million grant from the Department of Energy to develop and test a system that integrates solar and battery storage with a microgrid.
