Williams Cos. Inc. received approval from the US Federal Energy Regulatory Commission (FERC) for its 582-MMcfd Leidy South expansion project. The project will connect natural gas produced by Cabot Oil & Gas Corp. and Seneca Resources Co. LLC in the Marcellus and Utica regions of Pennsylvania with markets along the Atlantic seaboard by the 2021-22 winter heating season, Williams said. UGI Utilities Inc. will use its capacity to directly serve retail customers in northeast Pennsylvania.
Leidy South will include construction of two greenfield compressor stations, a 46,930 hp unit in Luzerne County, Pa., and 31,871 hp in Schuylkill County, Pa. (OGJ Online, Nov. 4, 2019). The project will use Williams’ existing Transco transmission corridor, replacing 6.3 miles of existing 24-in. OD Leidy Line A pipe with 36-in. OD pipe in Clinton County, Pa., and building 5.9 miles of new loop segments. It will also add horsepower at two existing compressor stations (12,000 hp in Wyoming County, Pa., and 35,871 hp in Columbia County, Pa.)
Seneca, Cabot, and UGI have binding, 15-year commitments for 100% of the project’s capacity.
Williams filed for FERC approval in August 2019.
