Transco interstate pipeline, operated by Williams has filed an application with the Federal Energy Regulatory Commission seeking authorization for its Leidy South project. The proposed project will connect robust supplies of natural gas in the Marcellus and Utica producing regions in Pennsylvania with markets along the Atlantic Seaboard.
“The Leidy South project will allow Williams to continue to grow our strategic footprint in the gas-rich Marcellus region, creating a unique opportunity to expand Transco by leveraging recent expansions on Williams’ Northeast Gathering & Processing assets in Pennsylvania,” said Micheal Dunn, chief operating officer of Williams.
The project will also expand Transco’s firm transportation capacity by 582400 dekatherms per day from the Leidy Hub and Zick interconnect to points downstream in Transco’s Zone 5 and Zone 6 market areas. The project is expected to cost $531 million and a target in-service of 1st December, 2021.
By maximizing the use of existing Transco pipeline infrastructure and rights of way in Pennsylvania, the project is designed to minimize environmental impacts which includes 6.3 miles of existing pipe replacement, 5.9 miles of new pipeline loop segments along the existing Transco pipeline corridor, and horsepower additions at two existing compressor facilities. Two new Greenfield compressor facilities in Pennsylvania is also planned for this project.
