The pipeline you are referring to is the new 128-mile gas pipeline built by Piedmont Natural Gas Co. Inc., to provide natural gas to Progress Energy’s Sutton new gas-fired electrical plant. Construction of the pipeline is complete, but pressure testing of the line will continue until summer, said Piedmont spokesperson David Trusty.
The new gas-fired plant will replace three older coal-fired units, and will reduce emissions from carbon dioxide, sulfur dioxide, and mercury, according to Progress Energy. The plant, which is estimated to cost $600 million, is scheduled to go online in 2014.
Progress Energy spokesperson Lisa Huffman said the Sutton plant will consume as much natural gas in one day as 2,600 households use in one year.
The Sutton pipeline is made up of two segments: eight miles of 30-inch pipeline starting near Davidson in Iredell County, and 120 miles of 20-inch pipeline that crosses Mecklenburg, Union, Anson, Richmond, Scotland, Robeson, Columbus and Brunswick counties before terminating at the Sutton plant. Delco is in Columbus County.
The pipeline is constructed of welded steel pipes and typically is buried three feet deep. The cost of the pipeline is estimated to be $217 million.
Natural gas for the Sutton pipeline originates in the gulf states and is piped to the northeast, including the Carolinas, through a 10,200-mile pipeline system owned by Williams Transco.
