Sunflower to Add Coal-fired Units at Holcomb Station
LCG, August 12, 2005--Sunflower Electric Power Corporation yesterday announced that its Board of Directors approved an agreement with Tri-State Generation and Transmission Association, Inc. to build two, 600-MW coal-fired units at Sunflowers Holcomb Station power plant in Kansas. Tri-State will own the new generating facilities and will contract with Sunflower to operate and maintain the units. Tri-State is a wholesale power supplier and is owned by 44 rural electric systems that serve customers in Colorado, Wyoming, New Mexico and Nebraska. The additional generation will supplement their long-term power supplies. A spokesperson for Tri-State stated that it plans to invest $2.5 billion in the new units, plus $700 million for up to 550 miles of 345-kV transmission lines stretching from the plant into eastern Colorado. The plans do not include for power to be delivered within the State of Kansas.With the high-level, Memorandum of Agreement now approved, more detailed agreements and plans will be developed. The schedule is expected to allow for construction to begin in 24-42 months, with a construction period of 42 months for the first unit. The units are likely to be constructed sequentially, with the second unit starting approximately a year after construction commences on the first unit.The new units will be built adjacent to the existing facilities at Holcomb Station. The existing plant, which became operational in 1983, has a generating capacity of 360-MW. The plant now burns low-sulfur coal mined in Wyomings Powder River Basin and delivered to the plant by rail.Sunflower has stated that it has secured all necessary permits for the expansion, and a spokesperson for the Kansas Corporation Commission (KCC) stated the agreement to build the power plants does not require the regulatory agency's approval, although Sunflower and Tri-State may need the KCC's authority to construct the transmission lines.
