Transco files to expand Mobile Bay gas lateral

Williams Partners LP’s Transco natural gas pipeline has filed an application with the US Federal Energy Regulatory Commission to expand a compressor station and provide additional firm transportation capacity to the US Southeast by second-quarter 2015.

The Mobile Bay South III expansion project is designed to provide 225 MMcfd of firm transportation on Transco’s Mobile Bay Lateral from the Station 85 4A Pooling Point and other receipt points at Station 85 in Choctaw County, Ala., to interconnections with Florida Gas Transmission and Bay Gas Storage in Mobile County, Ala.

The proposed expansion would involve adding compression at Station 85 along with upgrading existing equipment in Washington and Mobile counties, Ala. Transco expects to begin construction in second-quarter 2014, pending regulatory approval.

The company estimates project cost at $50 million.
