New England expands energy storage role for reliable wholesale markets


Six energy storage systems will be deployed in New England to help consumers save more energy and money, and to ensure the reliability of grid networks by increasing renewable energy capacity integrated with main grid networks.

NEC Energy Solutions is partnering with municipalities in the region to install more than 20MW of energy storage systems in Madison, Ashburnham, Templeton, Wakefield, Middleton and Taunton.

The energy storage systems will reduce the cost of energy transmission and capacity charges for the municipal utilities.

The system to be installed in Taunton is a 3MW/6MWh plant and will be one of the largest in New England to date. It is expected to help the municipal utility to enhance grid resiliency in the event of an outage due to severe weather and other causes.

NEC will supply its GSS Grid Storage and AEROS platforms to monitor and operate the energy storage plant in near real-time, a development which will help the utility to improve its demand response capabilities during peak periods.

Three of the projects including Ashburnham, Templeton and Wakefield are partnering with the Massachusetts Municipal Wholesale Electric Company as part of the company’s peak load forecasting and remote dispatch programme.

The energy storage projects have been made possible with funding from the Advancing Commonwealth Energy Storage (ACES) programme and the state Department of Energy Resources.

Funding has been secured following a successful pilot conducted by the Sterling Municipal Light Department which included a 2MW/3.9MWh system which became operational in December 2016 and has saved $1 million in consumer utility bills.
