The Leidy South Project is a proposed expansion of Williams’ existing Pennsylvania energy infrastructure designed to connect robust supplies of natural gas in northern and western Pennsylvania with growing demand centers along the Atlantic Seaboard in time for the 2021-22 winter heating season. The project will help the existing Transco pipeline system transport an additional 582,400 dekatherms of natural gas supply per day – enough natural gas to meet the daily needs of approximately 2.5 million homes.
- Minimize Impacts. By maximizing the use of the existing transmission corridor, our goal is to minimize the impact on property owners and the environment.
- Create Jobs. Construction of the Leidy South Project’s two greenfield compressor facilities is estimated to generate $100 million in economic activity within Pennsylvania, supporting 680 jobs with combined earnings of $28 million and produce $1.3 million in state tax revenue.
- Support Economic Growth. Pennsylvania’s economy is continuing to build momentum in recent years with significant growth in the natural gas industry leading the way.
The design of the Leidy South Project limits environmental impacts by maximizing the use of existing energy infrastructure. The proposed facilities include:
- Replacement of 6.3 miles of Transco’s existing 24-inch Leidy Line A with 36-inch pipe in Clinton County, Pennsylvania (Hensel Replacement)
- 2.4 miles of 36-inch pipeline loop in Clinton County, Pennsylvania (Hilltop Loop); and
- 3.5 miles of 42-inch pipeline loop in Lycoming County, Pennsylvania (Benton Loop);
- Compressor Station 605 – Uprate the two existing electric motor driven compressors from 15,000 horsepower (“hp”) to 21,000 hp each at Transco’s existing Compressor Station 605 in Wyoming County, Pennsylvania;
- Greenfield Compressor Station 607 – Install two turbine driven compressor units and cooling in Luzerne County, Pennsylvania;
- Compressor Station 610 – Add one turbine driven compressor unit and cooling at Transco’s existing Compressor Station 610 in Columbia County, Pennsylvania;
- Greenfield Compressor Station 620 – Install one turbine driven compressor unit in Schuylkill County, Pennsylvania;
- Appurtenant underground and above-ground facilities.
