The Butler-Warner Generation Plant is a hybrid power plant located in Cumberland County, North Carolina. It is owned and operated by the Fayetteville Public Works Commission. The plant has a total capacity of 304.9 MW and began operating in 1976. It utilizes a mix of technologies, including natural gas-fired combined cycle, natural gas-fired combustion turbine, solar photovoltaic, and battery energy storage. The battery energy storage system (BESS) has a capacity of 0.5 MWh and a duration of 1 hour, using lithium-ion battery (LIB) chemistry. The solar photovoltaic array uses a fixed tilt tracking system.
The plant's primary fuel source is natural gas. In the most recent year of data, the Butler-Warner Generation Plant generated 112,819 MWh of electricity, resulting in a capacity factor of 4.2%. The plant operates within the Duke Energy Progress East balancing authority and the SERC NERC region. It is ranked as the 16th largest power plant in North Carolina and 638th 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.
