WESTAR ENERGY ANNOUNCES SECOND QUARTER 2006 RESULTS

TOPEKA, Kan., Aug. 9, 2006 — Westar Energy, Inc. (NYSE:WR) today announced earnings of $35.1 million, or $0.40 per share, for the second quarter 2006 compared with earnings of $27.6 million, or $0.32 per share, for the second quarter 2005. The increase in earnings for the quarter was due primarily to increased retail sales and lower interest expense that together more than offset lower wholesale sales and increased operating expenses.

For the six months ended June 30, 2006, the company reported earnings of $61.7 million, or $0.71 per share, compared with earnings of $43.0 million, or $0.50 per share, for the same period in 2005. The increase in earnings for the first six months of 2006 was due primarily to increased retail sales, increased income from corporate-owned life insurance and lower interest expense that together more than offset lower wholesale sales and increased operating expenses.

Second Quarter Results

Westar Energy reported revenues of $406.6 million for the second quarter 2006 compared with $374.8 million for the same period in 2005. Retail sales for the second quarter 2006 increased $40.8 million or 15.4% compared with the same period of 2005 due to warmer weather

this year, higher industrial sales and additional revenues related primarily to increased recovery this year of fuel and purchased power costs through rates. Wholesale sales decreased $6.4 million for the second quarter of 2006 compared with the same period in 2005 due primarily to reduced market-based wholesale sales resulting from efforts to conserve low-cost coal resources for the benefit of retail customers during the summer cooling season. Energy marketing decreased $4.9 million for the second quarter 2006 compared with the same period of 2005 due primarily to less favorable mark-to-market contract valuations this year.

Fuel and purchased power expense for the second quarter of 2006 increased $10.1 million compared with the same period last year. The prior period’s fuel and purchased power expense was reduced due to a $13.0 million mark-to-market gain associated primarily with a favorable change in the value of a coal supply contract. Since implementing the retail energy cost adjustment (RECA), current fuel expense no longer reflects changes in the value of fuel supply contracts. Instead, changes in the value of fuel supply contracts are now recorded as either regulatory assets or liabilities. Operation and maintenance expense increased $9.7 million reflecting increased maintenance expense at the company’s generating stations, $2.9 million for amortization of deferred storm expense and increased Southwest Power Pool transmission network expense. Depreciation and amortization expense increased $7.7 million due primarily to the implementation of new depreciation rates. A July 7, 2006 decision by the Kansas Court of Appeals reversing (and remanding to the KCC for further consideration) the portion of the KCC’s December 2005 rate order allowing recovery of higher depreciation expense is discussed in the company’s second quarter Form 10-Q. Selling, general and administrative (SG&A) expense decreased $2.3 million due primarily to reduced legal expenses related to matters having to do with former management. The SG&A decrease was partially offset by increased pension and medical expense.

Other income for the second quarter 2006 was $3.9 million compared with $5.5 million for the same period in 2005. The change between periods is due primarily to reduced income from corporate-owned life insurance. Interest expense for the second quarter 2006 was $25.0 million compared with $27.7 million for the same period in 2005, reflecting the results of debt redemptions and lower interest rates due to refinancing activities.

Six-month Results

Westar Energy reported revenues of $746.6 million for the six months ended June 30, 2006 compared with $711.3 million for the same period of 2005. Retail revenues increased $46.3 million or 9.3% compared with the same period of 2005, due primarily to warmer weather this year, higher industrial sales and additional revenues related primarily to increased recovery this year of fuel and purchased power costs through rates. Wholesale sales decreased $22.5 million for the six months ended June 30, 2006 compared with the same period in 2005 due primarily to reduced market-based wholesale sales resulting from efforts to conserve coal for the benefit of retail customers during the summer cooling season. Energy marketing increased $7.4 million for the six months ended June 30, 2006 compared with the same period of 2005 due primarily to more favorable mark-to-market contract valuations this year.

Fuel and purchased power expense for the six months ended June 30, 2006 increased $10.3 million compared with the same period in 2005. The prior period’s fuel and purchased power expense was reduced due to a $25.3 million mark-to-market gain associated primarily with a favorable change in the value of a coal supply contract. Since implementing the RECA,

current fuel expense no longer reflects changes in the value of fuel supply contracts. Instead, changes in the value of fuel supply contracts are now recorded as either regulatory assets or liabilities. Operation and maintenance expense increased $14.0 million reflecting increased maintenance expense at the company’s generating stations, $4.9 million for amortization of deferred storm expense and increased Southwest Power Pool transmission network expense. Depreciation expense increased $12.9 million due primarily to the implementation of new depreciation rates. Selling, general and administrative (SG&A) expense decreased $5.3 million due primarily to reduced legal expenses related to former management and lower insurance costs. The SG&A decrease was partially offset by increased pension and medical expense.

Other income for the six months ended June 30, 2006 was $11.2 million compared with $3.6 million for the same period in 2005. The change between periods is due primarily to increased income from corporate-owned life insurance. Interest expense for the six months ended June 30, 2006 was $48.4 million compared with $57.6 million for the same period in 2005, reflecting the results of debt redemptions and lower interest rates due to refinancing activities.
