      Great Plains Energy Credit Agreement

On December 15, 2004, Great Plains Energy entered into a Credit Agreement with Bank of America, N.A., as Syndication Agent, The Bank of Tokyo-Mitsubishi, Ltd, Wachovia Bank, National Association and BNP Paribas, as Co-Documentation Agents, JPMorgan Chase Bank, N.A., as Administrative Agent, The Bank of New York, KeyBank National Association, The Bank of Nova Scotia, U.S. Bank National Association, Merrill Lynch Bank USA, Morgan Stanley Bank, Mizuho Corporate Bank, UMB Bank, N.A., PNC Bank, National Association, Bank Midwest, N.A. and UFJ Bank Limited (the "Great Plains Energy Facility").

The Great Plains Energy Facility is a revolving credit facility, with a term ending December 15, 2009, providing for loans and letters of credit not exceeding an aggregate of $550 million at any one time. So long as there is no default or unmatured default, Great Plains Energy may increase this amount by up to $50 million by increasing the commitment of one or more lenders which have agreed to such increase, or by adding one or more lenders with the consent of the Administrative Agent, which will not be unreasonably withheld. Available liquidity under the Great Plains Energy Facility is not impacted by a decline in credit ratings unless the downgrade occurs in the context of a merger, consolidation or sale. A default by Great Plains Energy or any of its significant subsidiaries of material other indebtedness totaling more than $25 million is a default under this facility. Great Plains Energy is required to maintain a consolidated indebtedness to consolidated capitalization ratio not greater than 0.65 to 1 .0 at all times. The Great Plains Energy Facility also contains a material adverse effect ("MAE") clause that requires Great Plains Energy to represent, prior to the issuance of any advance or letter of credit, that no event resulting in an MAE has occurred, except for advances to repay maturing commercial paper.

The Great Plains Energy Facility replaced two existing credit facilities, which are described in Item 1.02, below. The lenders in the Great Plains Energy Facility (excluding Morgan Stanley Bank, UMB Bank, N.A., Bank Midwest, N.A. and UFJ Bank Limited) were also lenders in these two credit facilities.

In addition, KCP&L had revolving credit facilities with JPMorgan Chase Bank, The Bank of New York and The Bank of Tokyo-Mitsubishi aggregating $75 million, which were replaced with the KCP&L credit agreement described below.

GREAT PLAINS ENERGY ANNOUNCES TIMING OF RELEASE OF 2005 EARNINGS GUIDANCE

Kansas City, MO, December 15, 2004 - Great Plains Energy Incorporated (NYSE:GXP) today announced the successful syndication of a $550 million, 5-year credit facility. The new Great Plains Energy credit line replaces a $150 million, 364-day line that matures in March 2005 and a $150 million, 3-year facility that matures in March 2007.

Concurrently with this closing, the Company's regulated electric utility subsidiary, Kansas City Power & Light Company (KCP&L), completed syndication of a $250 million facility, also with a 5-year term. This facility replaces $155 million in 364-day bilateral credit lines KCP&L had in place with seven individual banks.

The facilities were syndicated on a combined basis and were oversubscribed at $905 million. Allocations were made among the 16 participating institutions to reach the final combined total of $800 million, which represented a $100 million increase over the original target of $700 million. JP Morgan and Bank of America co-led the transaction.

"We are pleased to have completed these transactions," commented Andrea Bielsker, Chief Financial Officer. "Both Great Plains Energy and Kansas City Power & Light were able to obtain an increased level of committed liquidity for a 5-year period, with more attractive pricing and covenants than our previous lines. This successful transaction is evidence that our bank group supports our Company's operations and strategic direction. These lines give us significant additional flexibility to meet liquidity requirements as we execute our strategy in the years ahead."

The Company also announced that 2005 earnings guidance will be released in February 2005. This timing will allow KCP&L to gain additional regulatory clarity with regard to potential generation and environmental initiatives.
