NEC Energy Solutions, a unit of NEC Corp., announced that it is supplying the Sterling Municipal Light Department of Sterling, Massachusetts with a 2 MW, 3.9 MWh GSS grid energy storage solution.

Once complete in December of this year, it will be the largest battery-based energy storage system installed in New England and the first utility scale project in Massachusetts.

It will improve grid resiliency against weather-related power outages, while providing enhanced clean energy usage and cost savings to the town of Sterling. Town, State and NEC ES officials commemorated the project today in an official groundbreaking ceremony.

To reduce Sterling’s carbon footprint, SMLD has been installing large amounts of photovoltaic solar and is currently ranked seventh in the nation in installed PV per capita. However, SMLD desired greater resiliency and further modernization of its grid.

The energy storage system will work in conjunction with the overall installed base of PV solar to provide the needed energy resiliency, particularly to critical town departments such as police, dispatch, and fire service.

It will also provide transmission capacity charge savings from reducing peak demand, which will deliver energy cost saving benefits to the community. NEC ES is providing its turn-key GSS energy storage solution which includes a single 53′ container housing 3.9MWh of lithium ion batteries, a 2MW power conversion system, and proprietary NEC ES AEROS controls software suite. NEC ES will also provide service and maintenance packages to SMLD for the GSS energy storage installation.
