National Grid US grows demand response portfolio with EnergyHub’s DERMS


National Grid is using EnergyHub’s Mercury system as a single platform to manage demand response of residential and commercial and industrial (C&I) customers.

In 2018 National Grid centralised its ‘bring your own device’ (BYOD) programmes on the Mercury distributed energy resource management system (DERMS). Now the company also is using the platform for enrolment, forecast-based dispatch and reporting and settlement capabilities for their C&I resources.

National Grid’s C&I programme has enrolled 13 aggregators and over 900 individual sites in Massachusetts, New York, and Rhode Island. These represent over 400MW of load reduction capacity.

Through their residential BYOD programmes, National Grid has enrolled almost 30,000 thermostats and over 1,000 batteries.

“National Grid is committed to running a safe, sustainable, and efficient grid. Managing distributed energy resources is a key component of that mission,” said John Isberg, Interim senior vice president, chief customer officer at National Grid. “We are excited to be taking the next step in further developing our demand response programmes for the benefit of the grid and all of our customers.”

EnergyHub was developed for utilities to take an automated, data-driven and scalable approach to enrol and manage both individual site and aggregator-nominated flexibility. The system triggers targeted dispatch of aggregations or sites based on system forecasts. It generates and analyzes event performance data for reservation, performance and payment calculations.

As a single platform for multiple distributed resources, utility operational costs are reduced and silos are avoided.

“We’re excited to work with clients like National Grid to provide a centralized platform for managing resources at the grid edge, from behind-the-meter residential assets to commercial and industrial sites,” added Seth Frader-Thompson, president at EnergyHub.
