Exhibit 99.2

KANSAS CITY, MO - June 4, 2004 - Great Plains Energy (NYSE: GXP) separately announced today its plans to issue common stock and mandatory convertible securities in public offerings. The Company expects the issuance will dilute 2004 earnings by approximately $0.03 per share. Including the dilutive effect of the offering, the Company increases 2004 ongoing earnings guidance to $2.23 to $2.35 per share. The Company's previous guidance for 2004 ongoing earnings was $2.20 to $2.32 per share. Strong year-to-date performance driven by favorable wholesale electricity revenues, modestly favorable weather, and solid retail growth at Kansas City Power & Light provides the basis for the increased guidance range.

Great Plains Energy provides in its quarterly earnings releases descriptions of "ongoing earnings" in addition to earnings calculated in accordance with generally accepted accounting principles (GAAP). Great Plains Energy also provides its earnings guidance in terms of ongoing earnings. Ongoing earnings is a non-GAAP financial measure that differs from GAAP earnings because it excludes the effect of certain unusual items. The 2004 ongoing earnings guidance excludes the effect of KLT Gas operations and divestiture costs of $0.05 to $0.08 per share. Great Plains Energy is unable to reconcile its ongoing earnings guidance to GAAP earnings per share because we do not predict the future impact of unusual items.

We believe ongoing earnings provide to investors a useful indicator of our results that is comparable among periods because it excludes the effects of unusual items, which may occur on an irregular basis. Investors should note that this non-GAAP measure involves judgments by management including whether an item is classified as an unusual item. We use ongoing earnings internally to measure performance against budget and in reports for management and the board of directors.
