Kansas Electric Power Cooperative (KEPCo) signed Wolf Creek ownership contracts alongside KGE and KCPL in April 1979, securing KEPCo's ownership stake initially planned at 17% (later adjusted to 6%).
Wolf Creek Generating Station entered commercial operation in September 1985.
The NRC issued License Amendment 61 (later referenced as Amendment 69) authorizing an approximately 4.5% power uprate. The maximum reactor core power level increased from 3,411 MWt to 3,565 MWt; the NSSS power at uprate condition became 3,579 MWt.
Kansas Gas and Electric Company (KGE) and Kansas City Power & Light Company (KCPL) filed a license transfer application with the NRC seeking to transfer their possession-only interests to Westar Energy, Inc.
Kansas Electric Power Cooperative (KEPCo) restructured and refinanced its original Wolf Creek debt, aligning repayment with the plant's extended license through 2045. The restructuring resulted in a cumulative wholesale rate reduction of approximately 5%.
Great Plains Energy announced a proposed acquisition of Westar Energy valued at approximately $12.2 billion enterprise value (approximately $8.6 billion equity and cash consideration, plus approximately $3.6 billion assumed debt). The transaction included joint ownership of Wolf Creek.
Great Plains Energy and Westar Energy completed their mergers. Great Plains Energy merged into Evergy (with Evergy surviving), and Westar Energy survived as a subsidiary. Westar Energy and the direct subsidiaries of Great Plains Energy, including KCP&L, became wholly-owned subsidiaries of Evergy. Wolf Creek Nuclear Operating Corporation continued as the operator of Wolf Creek Generating Station.
