Placed into service on 1 May 2011, new service from the Mobile Bay South II expansion project led to an additional 380,000 dekatherms per day of southbound firm transportation capacity on the Mobile Bay Lateral from Transco’s mainline at Station 85 near Butler, Alabama, to its interconnect with Gulfstream Natural Gas System in Coden, Alabama.
The cost of the project was estimated around $35m.
The second phase of the company’s 85 North expansion project came into service on the same day, increasing the Transco pipeline’s capacity by an additional 218,500 dekatherms per day to serve electric power generating facilities in North Carolina.
Phase one of the 85 North expansion was placed into service in July 2010, adding capacity to transport an additional 90,000 dekatherms of natural gas per day to markets in Alabama.
The combined cost of the two phases of the 85 North expansion is estimated aroound $225m.
The current system capacity of the 10,000-mile Transco pipeline that transports natural gas to markets throughout the northeastern and southeastern US is approximately 9 billion cubic feet per day.
