Keystone Dam is a 70 MW hydroelectric power plant located in Tulsa County, Oklahoma. The plant began operating in 1968 and is owned and operated by the US Army Corps of Engineers (USCE-Tulsa District). It utilizes conventional hydroelectric technology with water as its primary fuel source, and consists of two generators. Keystone Dam is connected to the Southwest Power Pool (SPP) balancing authority and resides within the Midwest Reliability Organization (MRO) NERC region.
In terms of size, Keystone Dam ranks as the 8th largest out of 11 hydroelectric plants in Oklahoma, and 253rd out of 1464 nationally. The plant's latest annual generation was 1,583 MWh, resulting in a capacity factor of 0.3%. Recent news coverage related to the plant has focused on grid issues, industry trends, hazards, and regulatory matters.

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.
