SMLD has installed large amounts of solar PV in recent years, and is currently ranked 7th in the country for installed PV per capita. The department sought greater resiliency and modernization in its grid, as well as security against weather related power outage.
The storage system consists of a container housing 3.9 MWh of lithium ion batteries, a 2 MW conversion system and the NEC ES AEROS software suite. NEC will also provide a service and maintenance package as part of the deal.
The project was funded by a $1.46 million grant from the Massachusetts Department of Energy Resources (DOER), with additional funding and assistance from the U.S. Department of Energy, Office of Electricity. Clean Energy States Alliance also provided technical support on the project, through a grant fro the Barr Foundation.
The system will work in conjunction with the already installed base of solar PV to provide extra grid security, in particular to the towns emergency services. It will also reduce peak demand, providing energy cost savings to the whole community.
This project is the largest of its kind in New England and represents our commitment to deliver safe and reliable energy storage across the globe, says NEC Energy Solutions CEO Bud Collins. We are ready to implement further projects that could make Massachusetts one of the largest energy storage markets in the world.
NECs years of global energy storage experience helped us achieve our combined goals of resilience and cost savings, states SMLD General Manager Sean Hamilton. Using the right configuration and amount of storage will help to strengthen and modernize our electricity system.
