F. B. Culley Generating Station

F. B. Culley Generating Station is a 369-MWe coal-fired electricity-generating power plant, located southeast of Newburgh in Warrick County. It sits on the north bank of Ohio River, immediately adjacent and upstream of the Warrick Power Plant, and is owned and operated by Vectren (formerly Southern Indiana Gas and Electric Company). F. B. Culley has two units still in service: a 103.7-MWe Unit 2 (built in 1966) and a larger 265.2-MWe Unit 3 (built in 1973). Unit 1 was a 46 MW coal-fired generation unit established 1955 and closed in 2006.Environmental impactIn 1994, Vectren installed a flue-gas desulfurization system (scrubber) on Units 2 and 3 to reduce sulfur dioxide emissions. From 2001 to 2005, Vectren installed four selective catalytic reduction (SCR) devices on the coal-fired units, which successfully cut nitrogen oxide emissions by 80 percent. In 2006, a fabric filter was installed at Unit 3 to further reduce particulate matter emissions.
