ENGIE completes Massachusetts’ largest storage project

Platts:

One of first states to enact an energy storage target, Massachusetts, received its largest utility-scale energy storage system Tuesday when ENGIE and Holyoke Gas & Electric launched a 3 MW/6 MWh system connected to a solar farm near Boston.

Located adjacent to the former 136-MW Mt. Tom oil- and coal-fired power plant 90 miles west of Boston in Holyoke, Massachusetts, the battery energy storage system was connected to a 5.8-MW community solar PV project. ENGIE North America supplies power from the solar plant to local utility Holyoke Gas & Electric under a 20-year power purchase agreement, ENGIE Storage spokeswoman Anne Smith said in an email Tuesday.

As battery costs decline and policies are enacted to encourage energy storage development, companies are increasingly interested in the technology, particularly when it can be paired with generation resources allowing the flow of power to be more efficiently managed.

ENGIE is working on additional energy storage projects in the region. “Massachusetts is primed for growth in the energy storage market thanks to their progressive energy policy,” Smith said. Utilities in the state are required to procure 200 MWh of energy storage by 2020. Massachusetts also has a goal to generate 50% percent of its power from renewable energy sources by 2035.

The Mt. Tom solar plus storage system will be used to reduce peak demand on HG&E’s distribution grid, according to a statement. Rising demand-based costs throughout the New England market have been accounting for a large portion of energy costs, which has created pressure to reduce peak energy usage, according to the statement.

“This project is the perfect illustration of energy transformation in action – affordable, clean energy replacing traditional fossil fuel power generation,” Frank Demaille, ENGIE North America president and CEO, said in the statement.
