ENGIE North America and Holyoke Gas & Electric (HG&E) have announced plans for the largest utility-scale energy storage installation in Massachusetts. Green Charge, an ENGIE NA subsidiary, will operate the three-megawatt energy storage system at Mt. Tom Solar, which began operation in January of this year adjacent to the former Mt. Tom Power Station. The system will be used to optimize variable solar energy and reduce utility capacity costs for HG&E, the system’s customer while reducing stress on the HG&E distribution system. This project will contribute to rate stabilization for HG&E customers over the next 20 years. In addition, customers will benefit from improved power quality and reliability. Green Charge expects to complete installation by April 2018, in time for the peak summer months when capacity costs are highest.
With Green Charge Networks joining the ENGIE portfolio, its patented battery system technology that has enabled commercial & industrial customers to reduce their electric bills by 30 percent further amplifies ENGIE’s digital product suite for reducing customers’ resource usage, carbon emissions, and energy expenditure.
Demand Management Program, HG&E was awarded a $475,000 MA Department of Energy Resources (DOER) Grant. The funds will be used to contract with, schedule, measure, and analyze this state-of-the-art energy storage system. UMass Amherst will quantify the peak reduction value to the distribution system, accounting for equipment value, cost reduction potential, and overall project data. The goal of the grant is to provide research and recommendations on the future distribution system value of battery storage devices throughout the Commonwealth.
“Massachusetts is proud to be a national leader in energy efficiency programs that reduce overall consumption and we are committed to continuing our work to improve energy costs disproportionately affected by times of peak demand,” said Massachusetts Governor Charlie Baker. “The demonstration projects funded through these grants will strengthen our innovation economy and provide the Commonwealth with a roadmap for reducing our most expensive energy loads and securing our energy future.”
