Clean Energy Project to Enhance System Resiliency with Combination of Battery Storage, Energy Efficiency and Customer-Owned Devices

MANCHESTER, N.H. (May 21, 2019) – As part of its efforts to make the electric system more resilient and advance clean energy in New Hampshire, Eversource today announced that it will propose the Westmoreland Clean Innovation Project. The project includes a large-scale battery, energy efficiency efforts, and a program to provide incentives for customer-owned batteries, electric vehicle chargers, and smart thermostats. This portfolio of coordinated clean energy applications will reduce the frequency and duration of power outages in Westmoreland, avoid construction of a new overhead power line, help reduce greenhouse gas emissions in the region and provide important lessons to enable a more reliable and affordable clean energy future for New Hampshire customers.

Westmoreland school.“At Eversource, we’re focused on innovative solutions to better serve our customers, make the system more resilient to extreme weather, and advance affordable clean energy in New Hampshire,” said Eversource NH President Bill Quinlan. “As part of those efforts, we’re excited to propose the Westmoreland Clean Innovation Project and leverage different clean energy technologies to keep the power on for Westmoreland customers during emergencies.”

Served by one major power line in a rural portion of the state, the Town of Westmoreland has been more prone to outages when compared to other communities in recent years. The Westmoreland Clean Innovation Project will help ensure continued service to nearly 450 residential customers, local businesses, and critical facilities like the fire station, elementary school and county nursing home during emergencies and other interruptions. As a “non-wires alternative,” the project will allow the company to avoid construction of a $6 million, 10-mile distribution circuit to improve reliability. Over the course of its life, the project is expected to deliver cost savings to Eversource customers, significantly improve reliability to the town based on historic outage data, help manage energy use during times of peak demand and reduce greenhouse gas emission while informing similar clean energy projects in the future.

“We’re very pleased that Eversource chose Westmoreland as the site of this groundbreaking clean energy project in New Hampshire,” said Westmoreland Town Administrator Jo Ann Labarre. “Not only will this provide important electric reliability benefits for the town and our citizens, it puts us on the cutting-edge of our state’s clean energy future.” 

As part of the project, Eversource is proposing the installation of a 1.7 MW/7.1 MWh lithium ion battery that will provide back-up power for up to four hours.  This technology will be complemented by locally targeted energy efficiency initiatives and a statewide “Bring Your Own Device” program that provides incentives to participating residential customers whose customer-owned batteries, Wi-Fi thermostats, electric vehicle chargers or other devices are used during peak demand for load reduction. 

The statewide demand response program will be part of the filing for energy efficiency program updates at the NHPUC later this year, and it will include several opportunities reserved for customers in Westmoreland.  The company will use existing energy efficiency funds for additional outreach and marketing in Westmoreland to increase local participation in its programs. Eversource will seek approval for the 1.7 MW battery, which is projected to cost approximately $7 million, in its permanent distribution rate filing at the end of the month. If approved, the project is expected to begin construction in late 2020.
