Westar Energy, KEPCo Enter 38-Year Energy Agreement

TOPEKA, Kan., Aug. 7 – Westar Energy, Inc. (NYSE:   WR) and Kansas Electric Power Cooperative (KEPCo) announced today that KEPCo will continue to purchase a significant amount of its electricity requirements from Westar during the next 38 years. The sales agreement was signed Monday, Aug. 6, 2007.

KEPCo generates and transmits power for its 19 rural electric cooperative members, which collectively provide electricity to more than 300,000 rural homes and businesses in the eastern two-thirds of Kansas. The individual co-ops depend upon KEPCo to provide a long-term, reliable and economical energy supply.

“We are pleased to continue our long-standing relationship with KEPCo,” Doug Sterbenz, executive vice president and chief operating officer for Westar Energy, said. “Its members will benefit from Westar’s reliable, low-cost generation and be shielded from the swings experienced buying energy on the open markets.”

“KEPCo has long realized that using short-term purchase power agreements, relying on increasing amounts of natural gas-fired generation, and purchasing power in the spot market are not prudent business plans,” said Stephen Parr, executive vice president and chief executive officer.

KEPCo will purchase electricity based on Westar Energy’s cost to produce the power and combine it with KEPCo’s own resources to meet all of its members’ electrical needs. Westar will also assist KEPCo in managing its resources, a process that is beneficial to both KEPCo and Westar. The contract would become effective once reviewed by Federal Energy Regulatory Commission and the Rural Utilities Service.

“KEPCo’s valuable relationship with Westar is a key component of the power supply for our members. This purchase exemplifies how KEPCo is looking out for the long-term interests of our members and the rural consumers we serve,” Parr said.

Westar Energy serves about 670,000 Kansas retail customers within its service territory, which spans the eastern half of Kansas. Nearly 70 percent of the electricity it produces serves those customers directly. More than 80 percent of the electricity produced by Westar Energy is sold in Kansas. Profits from electricity produced at Westar’s energy centers that is sold at wholesale are used to reduce the rates its retail customers pay.

“Our neighboring municipal and rural electric utilities can benefit from our reliable, low-cost generation, and our customers benefit as those sales help to offset our costs,” Sterbenz said. “Four years ago, we shed our non-utility assets and reaffirmed that our focus was to be a Kansas electric utility. This commitment reaches beyond serving our retail customers.”

Like many utilities, Westar Energy is entering a phase of construction to ensure electricity is available to meet customers’ growing needs and to maintain required capacity margins that protect system reliability.

“The electric utility industry is on the cusp of unprecedented expansion in the next few years,” Sterbenz said. “Electricity providers are wise to be looking at long-term solutions for their customers.”
