RUS Approves Loan Guarantee for Seminole Electric Peaking Plants
LCG, October 7, 2004--Seminole Electric Cooperative, Inc. (SECI) announced that it received approval from the Rural Utilities Service (RUS) of the U.S. Department of Agriculture (USDA) for a $136.474 million loan guarantee to finance the expansion of Seminole's Payne Creek Generating Station.The existing, 500-MW Payne Creek Generating Station is located in Hardee County, Florida and began commercial operations on January 1, 2002. The initial configuration consisted of two, natural gas-fueled combustion turbines in combination with a steam turbine generator that uses heat recovered from the turbines' exhaust.Seminole now plans to install five, 62-MW Pratt & Whitney combustion turbines to provide an additional 310 MW of peaking capacity. Construction is planned to begin in February 2006, with operation commencing December 2006. The new units will be fueled by natural gas, with the ability to switch to low sulfur diesel fuel if desired for reliability or economic reasons. The Station is connected to both the Florida Gas Transmission and Gulfstream Natural Gas System pipelines.The site is owned by an SECI subsidiary and also contains the Hardee Power Station, which was originally owned by TECO Power Services Corporation. The Hardee Power Station, with a combined capacity of 370 MW, is now owned by Invenergy, LLC. The two existing stations share some of the infrastructure at the site.
