Williams Cos. Inc.’s Transco interstate pipeline has executed binding 15-year commitments with Seneca Resources Co. LLC and Cabot Oil & Gas Corp. for 100% of the 580 MMcfd of firm natural gas transportation capacity available under its proposed Leidy South expansion project.
Leidy South will increase deliveries of Marcellus and Utica shale production in Pennsylvania to East Coast consuming centers, with an expected in-service date of fourth-quarter 2021.
The capacity increase will affect Transco operations from the Leidy hub and Zick interconnect to points downstream in its Zone 6 market area. Transco’s capacity has increased 62% since 2013, the company said, including a 3-bcfd increase in Marcellus takeaway capacity.
Leidy South will consist of adding compression and looping to existing Transco line in Pennsylvania. The project also will include two capacity lease agreements; one with National Fuel Gas Supply Corp. from Leidy hub to Clermont, Pa., and a second with Meade Pipeline Co. from Zick to River Road on its Central Penn Line.
Transco plans to submit this month its request to start the prefiling process with the US Federal Energy Regulatory Commission.
