The Iola power plant, located in Allen County, Kansas, has a total capacity of 29.3 MW across 10 generators. The plant began operating in 1969 and is owned and operated by the City of Iola. The primary fuel source is distillate fuel oil (DFO), and the plant utilizes both natural gas internal combustion engines and petroleum liquids as technologies. Iola is considered a hybrid plant.
In the most recent year with available data, the plant generated 563 MWh, resulting in a capacity factor of 0.2%. The Iola plant operates within the Southwest Power Pool (SPP) balancing authority and the Midwest Reliability Organization (MRO) NERC region. It is ranked as the 4th largest plant out of 42 in Kansas, and 142nd out of 886 plants 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.
