HOUSTON, May 20 /PRNewswire-FirstCall/ -- El Paso Corporation (NYSE: EP) announced today that it has entered into an agreement to sell its 50-percent interest in Korean Independent Energy Corporation (KIECO) for approximately $276 million to Korea Power Investments Co., Limited.

KIECO owns a 1,800-megawatt combined-cycle LNG-fired power generation facility in the Republic of Korea that provides peak load power to the city of Seoul. El Paso acquired its interest in the facility in 2000.
