Deer Creek Station is a 300 megawatt (enough to power 240,000 homes) combined-cycle power generating facility fueled by natural gas and is located approximately two miles west and eleven miles north of Elkton, SD. The natural gas pipeline constructed for the project ties into the Northern Border Pipeline approximately 14 miles north of the site. A 345 kilovolt transmission line was constructed to carry the generated electricity from the plant to a Western Area Power Administration (WAPA) substation less than a mile south of the site. The heated exhaust generated from the gas turbine-generator set is used to heat a closed water system to create steam through a series of heat exchangers in the Heat Recovery Steam Generator (HRSG). The steam is used to power a second turbine-generator set. The exhaust is then vented out of the stack and the spent steam is piped to the Air Cooled Condenser where it is cooled and condensed for reuse in the HRSG.
