FOR IMMEDIATE RELEASE


Great Plains Energy’s Hawthorn Unit 5 plant back on-line

KANSAS CITY, MO, October 10, 2005 - Great Plains Energy Incorporated (NYSE:GXP) today announced that Kansas City Power & Light Company’s (KCP&L) Hawthorn Unit 5, a 565 MW coal-fired power plant, was brought back on-line September 30th after a 32-day outage due to a failed transformer. A back-up transformer will be used temporarily, which will limit Hawthorn Unit 5 to 500 MW of capacity until the installation of a new transformer, expected in June 2006.

KCP&L anticipates the financial impact of the Hawthorn Unit 5 outage to be offset by a lower level of coal conservation than previously planned and higher wholesale revenues in the fourth quarter driven primarily by significantly higher wholesale power prices than expected. The net effect on the Company’s 2005 financial results is not anticipated to affect previously announced earnings guidance, and there have been no service issues.

Great Plains Energy Incorporated (NYSE:GXP), headquartered in Kansas City, Missouri, is the holding company for Kansas City Power & Light Company, a leading regulated provider of electricity in the Midwest; and Strategic Energy LLC, a competitive electricity supplier. The Company's web site is www.greatplainsenergy.com.
