The Outer Cape Community Battery is a 25 MW battery energy storage system located in Barnstable County, Massachusetts. The plant began operating in 2022 and is owned and operated by Eversource. It is the largest of 126 power plants in Massachusetts, based on nameplate capacity, and ranks 668th nationally out of 1205 plants. The facility consists of a single generator utilizing batteries as its primary fuel source (MWH).
The battery system has a total storage capacity of 38 MWh, providing a duration of approximately 1.52 hours at its full 25 MW output. The battery chemistry is lithium-ion (LIB). The Outer Cape Community Battery operates within the ISO New England Inc. balancing authority and the Northeast Power Coordinating Council (NPCC) NERC region.

Capacity Factor
Positive values indicate net discharge (generation exceeds station load). Negative values indicate net charging. Pure battery storage plants are typically net negative due to round-trip efficiency losses.

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.
