US-based natural gas company Williams has filed an application with the Federal Energy Regulatory Commission (FERC) to expand its Transco natural gas pipeline by 308,500 dekatherms per day to serve markets in the southeastern US.

The company said that the new service from the 85 North project would be available in two phases, subject to FERC approval. Phase-1 would increase capacity by 90,000 dekatherms per day by summer 2010, while Phase-2 would increase capacity by 218,500 dekatherms per day by summer 2011.

The 85 North project will require construction of approximately 22 miles of 42-inch pipeline, in addition to a new 20,500hp compressor facility in Anderson County, South Carolina, as well as modifications to existing compressor facilities. Williams estimates that the project facilities will cost approximately $248 million.

Phil Wright, president of Williams’s natural gas pipeline business, said: Combined with our Mobile Bay South project, the 85 North expansion creates over half a billion cubic feet of take-away capacity from Station 85 to downstream markets.
