Transcontinental Gas Pipe Line Co. LLC secured authorization from Federal Energy Regulatory Commission staff to place part of the first phase of the Hillabee natural gas expansion project in service.
On June 7, commission staff granted the Williams Partners LP subsidiary permission to commence service for the project's 7.6 miles of 42-inch-diameter Alexander City loop in Tallapoosa County, the 42-inch-diameter Hissop loop in Coosa County, and compressor stations in Dallas and Coosa counties in Alabama.
The remainder of phase 1, also in Alabama, will include a new 32,000-horsepower compressor facility in Choctaw County, 4.6 miles of 48-inch pipe in Autauga and Chilton counties, and another 42-inch-diameter pipeline loop in Coosa County.
The entire first phase will create about 818.4 MDth/d of gas transportation capacity. Transco is scheduled to place phase 1 into service by the second quarter of 2017. The first phase was originally slated for service by May 1. According to Williams, the project's second phase is scheduled to be in service by the second quarter of 2020, while the third and final phase would be in service by the second quarter of 2021.
The project was approved by FERC in a Feb. 3, 2016, certificate order. Once fully in service, the project will provide about 1.13 million Dth/d in additional gas transportation capacity from receipt points in Choctaw County to an interconnection between the Transco system and the Sabal Trail pipeline in Tallapoosa County. Capacity was leased to the Sabal Trail Transmission LLC project of Spectra Energy Corp, NextEra Energy Inc. and Duke Energy Corp., which will use the capacity to help deliver gas to a new market connection hub in Osceola County, Fla.
