The Buck Steam Station is a 369-MW formerly coal-fired electrical power plant, owned by Duke Energy. There are also three natural gas-fueled combustion turbines at the location that provide an additional 93 MW, and two natural gas-fueled combined cycle turbines are planned for the near future. Remaining coal-fired units were decommissioned in mid-2011 and April 2013, with only natural gas units remaining.
Read more on WikipediaThe Buck power plant is a 697.9 MW natural gas-fired combined cycle facility located in Rowan County, North Carolina. It began operating in 2011 and consists of three generators. Duke Energy is both the parent company and, through Duke Energy Carolinas, LLC, the plant's operator. Buck ranks as the 12th largest power plant in North Carolina out of 16, and 311th nationally out of 945 plants. The plant operates within the Duke Energy Carolinas balancing authority and the SERC NERC region.
In its latest year of operation, Buck generated 3,954,876 MWh of electricity, achieving a capacity factor of 64.8%. Financial data indicates an installed cost of $939.57 per kW. The plant has a reported power purchase agreement (PPA) price of $25 per MWh, according to FERC and FERC EQR data.

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.
