Columbia-based Dominion Carolina Gas Transmission submitted plans to federal regulators for a $119.3 million project that involves building about 60 miles of natural gas transmission pipelines to deliver 80,000 dekatherms per day to local commercial, industrial, and power generation customers.
Called the Transco to Charleston Project, the company’s plans involve construction of 55 miles of 12-inch diameter natural gas transmission pipeline in Spartanburg, Laurens, Newberry, and Greenwood counties, according to documents filed with the Federal Energy Regulatory Commission. The project also involves building approximately 5 miles of 4-inch diameter natural gas transmission pipeline in Dillon County.
Additionally, Dominion Carolina proposes to install two 1,400-horsepower compressor units at existing Moore Compressor Station in Spartanburg County; three 1,200 hp compressor units at new Dorchester Compressor Station in Dorchester County.
Also, Dominion Carolina plans to convert an existing 1,200 hp compressor unit from standby to use the unit for service, at existing Southern Compressor Station in Aiken County.
The project proposed in-service date is Nov. 1, 2017, according to the documents.
This is the second major pipeline project submitted by Dominion Carolina to the federal government. In June, the company notified regulators of plans to build a new 8-inch, underground gas pipeline across Lower Richland County to International Paper’s operations near Eastover.
The company, in a filing with the commission, said the project is estimated to cost about $36.3 million and will cover a 28-mile route originating from the DAK Americas facility in Calhoun County.
The pipeline will provide 18,000 dekatherms per day of natural gas to International Paper, which is converting from coal and fuel oil to natural gas for generation of electricity used in the production of pulp paper products. International Paper also uses compressed natural gas delivered by truck.
