Jasper Generating Plant
SCE&G’s Jasper generating plant represents the latest in clean-burning, gas-fired technology. The 875-megawatt facility reinforces the company’s belief that the most reliable way to operate its system is by owning its own generation, meaning that SCE&G owns and operates enough power plants to produce enough electricity to successfully serve its customers.

Just one of SCE&G’s combustion turbine plants, the Jasper plant is the largest on SCE&G’s system. The Jasper plant came on line in May, 2004, as one of 22 generating sites the SCE&G’s system, increased the company’s electric output by more than 20 percent to approximately 5,800 megawatts.

Environmental Initiatives

  • Each unit has a steel exhaust stack, 190 feet tall, equipped with gas analyzers that continuously measure the amount of pollutant gases in the exhaust stream.
  • Equipped with low-NOx combustion systems to control nitrogen oxide emissions. SCR (Selective Catalytic Reduction) is utilized to further lower NOx emissions. Sulfur emissions are controlled by limits on sulfur content in the fuel. Particulate emissions from the firing of natural gas and No. 2 fuel oil are negligible.
  • The plant’s cooling system is closed-cycle, drawing make-up water from Beaufort-Jasper Water and Sewer Authority’s adjacent canal. Cooling tower blowdown and boiler blowdown are returned to the canal via holding ponds where it experiences mixing with effluent from the nearby BJWSA water plant. This return-water is carefully monitored with on-line instrumentation to ensure its purity.

Plant Facts

  • Located in Jasper County, SC, near Hilton Head, SC and Savannah, GA.
  • Began commercial operation in 2004.
  • In full operation the plant burns 6.6 million cubic feet f natural gas an hour. To put that in perspective, the cities of Columbia and Charleston each burn approximately 4 million cubic feet of natural gas per hour on a cold winter day.
  • The plant contains 117,233 linear feet of pipe, including 75,729 above ground and 41,504 below ground. Since there are 5,280 feet in one mile, there was more than 22 miles of pipe used in the construction of the facility.
  • More than 22,000 cubic yards of concrete were used in constructing the plant. That’s enough concrete to build a sidewalk adjacent to I-26 between Columbia and Orangeburg.
  • The Jasper Generating Station is capable of producing enough electricity to serve more than 280,000 homes.
  • Pays approximately $4.1 million in property taxes annually.
  • Employs 40 employees.
