Increased gross margin* of $234.7 million due to
approximately $150 million from the full-year
impact of new retail rates which took effect in
2009, and about $105 million due to favorable
weather;

Key Earnings Drivers

Increased other operating expense of $61.4
million primarily driven by $18 million increase in
plant operating and maintenance expenses,
recognition of a $16.8 million loss attributed to
Iatan 1 environmental and Iatan 2 construction
costs, $15 million in general taxes and
approximately $5 million due to other accounting
effects of the KCC November rate order;

Increased depreciation and amortization of $29.4
million including additional regulatory amortization
from 2009 rate cases, a full year of depreciation on
Iatan 1 and the commencement of depreciation on
Iatan 2 for the KS jurisdiction;

Decreased non-operating income and expense of
$14.6 million principally due to lower AFUDC
equity; and

Increased income tax expense of $59.7 million

Capital Expenditures Forecast

•Full-year impact from new KS rates

•True-up date in MO rate cases at end of 2010; new rates expected to be effective early May 2011
(KCP&L) / early June 2011 (GMO)

•Regulatory lag January - April from new rail contract for KCP&L in Missouri (no FAC)

•Iatan 2 depreciation effective with new rates will be lower due to lower depreciable plant from
additional amortization granted during the CEP to maintain credit metrics

Construction Accounting - Missouri

•Missouri jurisdictional share of Iatan 2 carried as a regulatory asset until effective date of new rates in
MO

–Carrying cost reduces interest expense

–Iatan-related O&M and property taxes deferred as regulatory asset until effective date of new rates

–Depreciation expense deferred as regulatory asset until effective date of new rates

–Iatan 2 system energy value recorded to regulatory asset as an offset to costs listed above

Interest Expense

•Interest expense impacted by carrying cost offset, new long-term debt issued in 2010 and new debt
anticipated in 2011

Considerations for 2011

Weather-Normalized MWh Sales

•Expectation is for growth of 0.7 percent compared to 2010 weather-normalized level

O&M

•Projected to be consistent with levels requested in rate cases

Generation Fleet

•Projected EAF for combined fleet - 83%

•LaCygne outage expected to conclude mid-March

•Wolf Creek refueling and expanded maintenance outage beginning in late 1Q

Taxes

•No cash taxes in 2011 as a result of bonus depreciation / NOL utilization

•Effective tax rate of approximately 34% based on normal conditions

Gross Margin Reconciliation

31

March 2011 Investor Presentation

Gross margin is a financial measure that is not calculated in accordance with generally accepted accounting principles (GAAP).Gross
margin, as used by Great Plains Energy, is defined as operating revenues less fuel, purchased power and transmission of electricity by
others.The Company’s expense for fuel, purchased power and transmission of electricity by others, offset by wholesale sales margin, is
subject to recovery through cost adjustment mechanisms, except for KCP&L’s Missouri retail operations.As a result, operating revenues
increase or decrease in relation to a significant portion of these expenses.Management believes that gross margin provides a more
meaningful basis for evaluating the Electric Utility segment’s operations across periods than operating revenues because gross margin
excludes the revenue effect of fluctuations in these expenses.Gross margin is used internally to measure performance against budget and
in reports for management and the Board of Directors.The Company’s definition of gross margin may differ from similar terms used by
other companies.A reconciliation to GAAP operating revenues is provided in the table above.
