This combined Current Report on Form 8-K is being furnished by Great Plains Energy Incorporated (Great Plains Energy) and Kansas City Power & Light Company (KCP&L).  KCP&L is a wholly owned subsidiary of Great Plains Energy and represents a significant portion of its assets, liabilities, revenues, expenses and operations.  Thus, all information contained in this report relates to, and is furnished by, Great Plains Energy.  Information that is specifically identified in this report as relating solely to Great Plains Energy, such as its financial statements and all information relating to Great Plains Energy’s other operations, businesses and subsidiaries, including KCP&L Greater Missouri Operations Company, formerly Aquila, Inc. (GMO), does not relate to, and is not furnished by, KCP&L.  KCP&L makes no representation as to that information.  Neither Great Plains Energy nor GMO has any obligation in respect of KCP&L’s debt securities and holders of such securities should not consider Great Plains Energy’s or GMO’s financial resources or results of operations in making a decision with respect to KCP&L’s debt securities.  Similarly, KCP&L has no obligation in respect of securities of Great Plains Energy or GMO.

Item 8.01 Other Information

On March 18, 2009, the Missouri Public Service Commission (the “MPSC”) issued an order in the pending KCP&L and GMO rate cases moving the expected effective date of the MPSC’s orders in these cases from August 5, 2009 to September 5, 2009.  Great Plains Energy and KCP&L will evaluate potential alternatives to mitigate the financial impacts of this delay.  However, there is no assurance that these impacts can be wholly or partially mitigated, and they could have a significant adverse effect on Great Plains Energy’s and KCP&L’s results of operations.

The order also contained certain conditions regarding adjustments to reserves and rate base amounts associated with Iatan Unit No. 1, as well as including a portion of Iatan Unit No. 1 costs in rates on an interim basis, subject to refund, pending a true-up of costs in KCP&L’s and GMO’s next Missouri rate cases.  The order does not provide sufficient detail for Great Plains Energy or KCP&L to reasonably quantify the impact of these conditions.  KCP&L and GMO believe that the MPSC exceeded its authority in establishing these conditions in a procedural order, and will seek rehearing and/or judicial review to remove or clarify these conditions.  It is not possible to predict the outcome of these proceedings.  It is possible that the final orders from the MPSC will authorize a lower rate increase than what either or both KCP&L or GMO have requested, or no increase or a rate reduction.  Management cannot predict or provide any assurances regarding the outcome of these proceedings.

Item 7.01 Regulation FD Disclosure

The information contained in Item 8.01 above is incorporated by reference herein.

Great Plains Energy estimates, based upon the amount of rate increases requested by both KCP&L and GMO in Missouri, that the impact of the delay would be to reduce 2009 earnings by approximately $0.10 per share of Great Plains Energy common stock, if not otherwise mitigated.  KCP&L estimates that the impact of the delay on its 2009 earnings would be approximately $0.06 per share of Great Plains Energy common stock, if not otherwise mitigated.  Great Plains Energy and KCP&L will evaluate potential alternatives to mitigate the financial impacts of this delay.  However, there is no assurance that these impacts can be wholly or partially mitigated, and they could have a significant adverse effect on Great Plains Energy’s and KCP&L’s results of operations.  Great Plains Energy reaffirms its 2009 earnings guidance range of $1.10 to $1.40 per share.

The information under this Item 7.01 is being furnished and shall not be deemed filed for the purpose of Section 18 of the Securities Exchange Act of 1934, as amended.  The information under this Item 7.01

shall not be deemed incorporated by reference into any registration statement or other document pursuant to the Securities Act of 1933, as amended, unless otherwise expressly indicated in such registration statement or other document.
