Phase II of the project will increase the pipeline’s capacity by an additional 218,500 dekatherms per day by the summer of 2011, which will serve new and existing electric power generating facilities in North Carolina.

Phase I of the 85 North project required adding a combined 17,900 horsepower at two existing Transco compressor facilities in Alabama. Phase II of the project will require the addition of approximately 22 miles of 42-inch pipeline in Alabama, South Carolina and North Carolina.

Phase II will also require a new 20,500 horsepower compressor facility in South Carolina and modifications to several existing compressor stations. The total cost of the project is approximately $241m.

The Transco pipeline is a 10,000-mile pipeline system which transports natural gas to markets throughout the northeastern and southeastern US. The current system capacity is approximately 8.6 billion cubic feet per day.

Phil Wright, president of Williams’ natural gas pipeline business, said: “This project is a great example of how Williams is working closely with its customers to fuel the increasing demand for electric power generation throughout the Southeast with clean-burning natural gas.”
