Petersburg Generating Station is a major coal-fired power plant in Indiana, rated at 2.146-GW nameplate capacity. It is located on the White River near Petersburg in Pike County, Indiana, just 1 mile (1.6 km) upstream from a much smaller coal-fired Frank E. Ratts Generating Station. Petersburg G.S. is owned and operated by AES Indiana.
Read more on WikipediaAES Petersburg is a 1349.9 MW hybrid power plant located in Pike County, Indiana. The plant began operating in 1967 and is owned by AES and operated by AES Indiana. It utilizes both conventional steam coal and petroleum liquids (DFO) as fuel sources across its five generators. AES Petersburg operates within the Midcontinent Independent Transmission System Operator, Inc. (MISO) balancing authority and the ReliabilityFirst Corporation (RFC) NERC region.
The plant's latest annual generation was 5,392,718 MWh, resulting in a capacity factor of 45.6%. AES Petersburg has an installed cost of $1580.27 per kW, according to FERC data. The plant is ranked as the 1st of 2 largest power plants in Indiana, and 6th out of 60 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.
