The Nantucket Hybrid plant is a 22.4 MW hybrid power plant located in Nantucket County, Massachusetts. The plant began operating in 2019 and is owned and operated by Nantucket Electric Co. The primary fuel source is petroleum liquids (DFO), and the plant incorporates battery storage. It has three generators and a battery energy storage system (BESS) with 48 MWh of storage capacity and an 8-hour duration, utilizing lithium-ion battery chemistry (LIB). The plant operates within the ISO New England Inc. balancing authority and the Northeast Power Coordinating Council (NPCC) NERC region.
In its most recent year of operation, Nantucket Hybrid generated 77 MWh of electricity, resulting in a capacity factor of 0.0%. The plant is ranked 6th out of 17 similar facilities in Massachusetts and 175th out of 886 nationally.

No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
