FERC Tuesday gave Transcontinental Gas Pipe Line (Transco) the green light to place into service an expansion of its pipeline system that will serve markets in the southeastern United States.

The Mobile Bay South facilities, which are going into operation weeks ahead of schedule, are designed to create 253,500 Dth/d of southbound, year-round firm capacity on the Mobile Bay Lateral from Transco’s mainline at Station 85 near Butler, AL, to its interconnect with Gulfstream Natural Gas System in Coden, AL (see Daily GPI, Sept. 23, 2008). Transco is a pipeline subsidiary of Oklahoma-based The Williams Companies.

“Combined with our Station 85 North expansion, the Mobile Bay South project creates over half a billion cubic feet [a day] of takeaway capacity from Station 85 to downstream markets,” said Phil Wright, president of Williams’ natural gas pipeline business.

“The Mobile Bay South project will enable us to provide firm southbound transportation service for growing domestic supplies from new pipeline interconnects at Station 85 to markets in southwest Alabama and Florida, as well as third-party storage facilities. In addition, it will allow us to maintain the current capacity of the lateral to supply our traditional customers through northbound service to Station 85.”

The Mobile Bay South project, which were filed at the Federal Energy Regulatory Commission in September 2008, primarily consisted of the construction of a 9,470-hp compressor facility at Station 85.
