GREAT PLAINS ENERGY ANNOUNCES FIRST QUARTER FINANCIAL RESULTS

Maintenance outages at KCP&L and reduced gross margins at SE lead to lower Q1 results

Kansas City, MO, May 2, 2007 - Great Plains Energy Incorporated (NYSE:GXP) today announced first quarter 2007 reported earnings of $23.0 million or $0.28 per share, compared to a first quarter 2006 loss of $1.5 million or $0.02 per share. Core earnings, which exclude net mark-to-market gains and losses on energy contracts and other items, were a loss of $11.0 million or $0.13 per share in the first quarter of 2007, compared to core earnings of $25.4 million or $0.34 per share in the first quarter of 2006. Reported earnings are reconciled to core earnings in attachment B.

Great Plains Energy’s core earnings declined in the first quarter due primarily to three issues. KCP&L’s core earnings were impacted by plant outages which occurred during a period of cold weather and constrained transmission. As a result, KCP&L experienced decreased wholesale sales, increased purchased power costs, and increased fuel expense due to higher natural gas usage. Strategic Energy’s core earnings were negatively impacted by bad debt and customer attrition in the small business segment and an increase in purchased power costs associated with a resettlement in the first quarter for 2006 deliveries.

Chairman and CEO Michael Chesser commented, “Our team has managed through several operational challenges in the first quarter. None of the issues, however, has altered the long term growth path that we believe our Comprehensive Energy Plan provides.” Mr. Chesser continued, “From a strategic perspective, the first quarter was marked by significant successes. We announced our proposed acquisition of Aquila, filed new rate cases in both Missouri and Kansas, and reached a collaborative agreement with the Sierra Club that removes the last of the legal challenges to our Comprehensive Energy Plan.”

Based upon first quarter results, Great Plains Energy is adjusting 2007 core earnings guidance to a range of $1.65 to $1.85 per share, compared to the previous range of $1.80 to $2.00. The change in guidance is due to a reduction in Strategic Energy’s segment guidance to a range of $0.07 to $0.13 per share from a previous range of $0.21 to $0.28 per share. Further, although not anticipated to affect overall core earnings for 2007, segment guidance reflects an expense shift between the KCP&L and “Other” segments of approximately $0.17 per share due to the Aquila transaction and financing activities. The expected shift increases KCP&L’s core earnings guidance to a range of $1.92 to $2.04 per share and increases the expected loss from the “other” category to a range of $0.32 to $0.34 per share.

Kansas City Power & Light

KCP&L reported first quarter 2007 earnings and core earnings of $2.1 million or $0.02 per share. KCP&L earnings for the first quarter last year were $13.0 million or $0.17 per share, with core earnings of $18.8 million or $0.25 per share. Revenues for the first quarter of 2007

-Page 2-

were $256 million compared to $240 million for the first quarter of 2006. Retail revenues were $217 million, up from $189 million in the first quarter of 2006 due to favorable weather, higher retail rates, and customer growth. Wholesale revenues in the first quarter decreased from $48 million last year to $34 million due to lower wholesale sales volume resulting from plant outages and higher retail volume, as well as average wholesale prices that were 22% lower than last year.

Maintenance outages at two of KCP&L’s baseload coal units during a period of cold weather and constrained transmission led to increased use of gas-fired generation and increased purchased power expense during the first quarter of 2007. As a result, fuel expense increased $6.2 million and purchased power expense rose $11.3 million compared to last year. Operating expenses in the first quarter were also higher than last year due to increased maintenance expense and the anticipated increase in pension costs due to the reset of the level of pension costs in KCP&L’s rates effective January 1, 2007.

In addition to the rate cases KCP&L filed in Missouri and Kansas during the first quarter, Great Plains Energy, KCP&L and Aquila filed applications with the Missouri Public Service Commission and the Kansas Corporation Commission in early April seeking approval of the proposed Aquila transaction.

KCP&L continues to execute on its Comprehensive Energy Plan. The LaCygne 1 SCR installation is expected to be completed in the second quarter of 2007, and construction at Iatan 2 is on schedule. Additionally in the first quarter KCP&L, Sierra Club and Concerned Citizens of Platte County signed a collaboration agreement under which KCP&L agreed to pursue a set of initiatives including energy efficiency, renewable energy, lower emission permit levels at its Iatan and LaCygne generating stations and other initiatives designed to offset carbon dioxide emissions. KCP&L will address these matters in its future integrated energy resource plan, in collaboration with other key stakeholders. Full implementation of the terms of the agreement will necessitate approval from the appropriate authorities, as some of the initiatives in this agreement require either enabling legislation or regulatory approval.

Strategic Energy

Strategic Energy reported earnings of $27.1 million or $0.33 per share in the first quarter of 2007, compared to a loss of $10.9 million or $0.15 per share last year. Core earnings were a loss of $6.9 million or $0.08 per share, compared to a profit of $10.2 million or $0.13 per share in the first quarter of 2006.

The decrease in core earnings during the first quarter was primarily attributable to a lower average retail gross margin per MWh due to the disposition of previously-acquired power at lower than contracted prices caused by early terminations in the small business segment and the increased purchased power expense related to the previously mentioned resettlement. The average retail gross margin per MWh in the first quarter of 2007 was $15.79. Excluding net mark-to-market gains on energy contracts, average retail gross margin per MWh was $2.16. This compares to an average retail gross margin per MWh, excluding net mark-to-market losses on energy contracts, of $7.67 last year. Strategic Energy also experienced an increase in bad debt expense in the small business segment and recognized potential penalty expense related to the purchased power adjustment.

Strategic Energy’s delivered volume increased 15% to 4.2 million MWhs during the first quarter from 3.7 million MWhs last year. Total backlog at Strategic Energy grew 50% in the first quarter to 34 million MWhs as new sales volume remained strong at 7.5 million MWhs in the first quarter of 2007, up slightly from 7.3 million MWhs in the same period in 2006. The average length of new and re-signed contracts remained at 18 months in the first quarter of 2007, unchanged compared to last year. Delivered volume during the quarter combined with 2007 backlog totaled 17.2 million MWhs at the end of the first quarter of 2007, compared to 13.8 million MWhs delivered and contracted for 2006 as measured at the same point last year.

Other

In the first quarter of 2007, the “other” category loss was $6.2 million or $0.07 per share compared to a loss of $3.6 million or $0.04 per share last year. The greater loss in the “other” category is primarily attributable to a decline in available tax credits from affordable housing investments and overall higher expenses at the holding company.

Non-GAAP Financial Measure

Great Plains Energy provides in its earnings releases descriptions of “core earnings” in addition to earnings calculated in accordance with GAAP. Great Plains Energy also provides its earnings guidance in terms of core earnings. Core earnings is a non-GAAP financial measure that differs from GAAP earnings because it excludes the effects of discontinued operations, certain unusual items and mark-to-market gains and losses on energy contracts. Core earnings for historical periods are reconciled to GAAP earnings in attachment B.

The Company believes core earnings provide to investors a meaningful indicator of its results that is comparable among periods because it excludes the effects of discontinued operations, certain unusual items and mark-to-market gains and losses on energy contracts. These items are excluded from core earnings because they may not be indicative of Great Plains Energy’s prospective earnings potential. Investors should note that this non-GAAP measure involves judgments by management, including whether an item is classified as an unusual item. Core earnings is used internally to measure performance against budget and in reports for management and the Board of Directors. Great Plains Energy’s definition of core earnings may differ from similar terms used by other companies.

1  This is a non-GAAP financial measure that differs from GAAP because it excludes the impact of
unrealized fair value gains or losses. Management believes this measure is more reflective of
average retail gross margins on MWhs delivered due to the non-cash nature and volatility of
changes in fair value related to non-hedging energy contracts and from cash flow hedge
ineffectiveness. Management and the Board of Directors use this as a measurement of Strategic
Energy's realized average retail gross margin per delivered MWh, which are settled upon delivery
at contracted prices.

3 Segment guidance reflects an expense shift between the KCP&L and “other” segments   of approximately $0.17 per share due to the Aquila transaction and financing activities.   The expected shift increases KCP&L’s core earnings guidance to a range of $1.92 to   $2.04 per share and increases the expected loss from the “other” category to a range of   $0.32 to $0.34 per share. This shift is not anticipated to affect overall core earnings for   2007.
