Sterling, Mass, picks NEC for largest storage in region

NEC Energy Solutions, a subsidiary of NEC Corp, announced yesterday it is supplying the Sterling (Mass) Municipal Light Dept (SMLD) with a 2-MW, 3.9-MWH GSS-brand grid energy storage system. Once deployed in December, it will be the largest battery-based energy storage system installed in New England and the first utility scale project in Massachusetts, NEC said.

The system will improve grid resiliency against weather-related power outages while providing enhanced clean energy usage and cost savings to the town, it added. Town, state and NEC ES officials commemorated the project yesterday in an official groundbreaking ceremony.

To reduce Sterling's carbon footprint, SMLD has been installing large amounts of PV solar and is currently ranked seventh in the nation in installed PV per-capita, NEC said. The utility wanted greater resiliency and further modernization of its grid, particularly for reliability in supplying power to critical town departments such as police, dispatch and fire service.

The system will provide transmission capacity-charge savings by reducing peak demand, which will deliver energy cost saving benefits to the community, it added. The turn-key system includes a single 53-foot container housing 3.9 MWH of lithium ion batteries, a 2-MW power conversion system and NEC's AEROS controls software suite.

NEC will provide service and maintenance to SMLD, too.

The project was funded in part by a $1.46 million grant from the Massachusetts Dept of Energy Resources (DOER) with added financial and technical assistance from the US DOE's Office of Electricity and Sandia National Lab, NEC said.
