The 401 South power plant, located in Berkshire County, Massachusetts, is a hybrid solar and battery storage facility with a total capacity of 1.5 MW. The plant began operating in 2023 and is owned and operated by Madison Energy Investments LLC. It consists of two generators utilizing both solar photovoltaic technology with fixed-tilt tracking and battery energy storage. The battery energy storage system (BESS) has a capacity of 2 MWh, providing a duration of 2 hours and employing lithium-ion battery (LIB) chemistry.
401 South's primary fuel source is listed as MWH. In its first year of operation, the plant generated 403 MWh, resulting in a capacity factor of 3.1%. The plant operates within the Southern Company Services, Inc. - Trans balancing authority and the Northeast Power Coordinating Council (NPCC) NERC region. In terms of size, 401 South ranks 122nd out of 126 power plants in Massachusetts and 1161st out of 1205 plants nationally.

This plant's balancing authority participates in the Southeast Energy Exchange Market (SEEM). SEEM is a bilateral exchange — no public nodal pricing.
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.
