New energy-storage options emerging in New England; ISO-NE publishes primer and makes FERC filing on market participation
June 22 update: Information added on ISO-NE’s May FERC filing. Proposed project megawatts (MW) were also updated to reflect the withdrawal of 50 MW of battery storage to have been included as part of a proposed new natural-gas-fired generator.
For the first time, grid-scale (or utility-scale) battery storage projects are seeking to join New England’s regional power system. Late last year, three projects with a combined 94 megawatts (MW) in nameplate capacity applied for interconnection in Maine, with one planning to go live by the end of 2016 and the other two in 2019.*
