New England Power Company - Nantucket County - ISONE

Nantucket Hybrid is a 22.4 MW operating hybrid power plant in Nantucket County, Massachusetts, combining petroleum-liquid generation with a 6 MW/48 MWh Tesla lithium-ion battery energy storage system at National Grid's Bunker Road substation and an on-island backup diesel generator. The facility provides contingency support for Nantucket's undersea transmission supply during peak demand and N-1 cable outages, deferring the need for a third submarine cable.
