Item 1.01 Entry into a Material Definitive Agreement

As reported in the Quarterly Report on Form 10-Q of Great Plains Energy Incorporated ("Great Plains Energy") for the quarter ended March 31, 2009, KCP&L Greater Missouri Operations Company ("GMO"), a wholly-owned subsidiary of Great Plains Energy, and other parties to GMO's pending electric rate case before the Missouri Public Service Commission (the "MPSC") informed the MPSC on May 11, 2009 that they had reached an agreement in principle to settle the pending rate case. As contemplated by the agreement in principle, on May 22, 2009, GMO, the Staff of the Missouri Public Service Commission ("Staff"), the Office of the Public Counsel ("OPC"), Missouri Department of Natural Resources ("MDNR") and Dogwood Energy, LLC filed a Non-Unanimous Stipulation and Agreement (the "Agreement") with the MPSC. From time to time, GMO purchases wholesale electricity from Dogwood Energy. A copy of the Agreement is attached hereto as Exhibit 10.1 and is incorporated herein by reference.

The Agreement is consistent with the agreement in principle, and provides for, among other things, an increase in annual revenues of approximately $63 million ($48 million for GMO's MPS jurisdiction and $15 million for GMO's L&P jurisdiction) effective September 1, 2009. Parties may challenge the prudence of the cost of the Iatan Unit No. 1 environmental project and the cost of facilities used in common by Iatan Units No. 1 and No. 2 in GMO's next rate case, but the GMO Missouri jurisdictional portion of any proposed rate base prudence disallowances will not exceed $15 million in aggregate. The Agreement also provides for the continuation of GMO's fuel adjustment clauses.

The Agreement is subject to MPSC approval, and will be voidable if not approved in its entirety. It is possible that the MPSC may approve the Agreement with changes, or may not approve the Agreement.
