Williams Projects Go In-Service Early as 2020 Ends
TULSA, Okla. – Williams said early in-service capacity was achieved for three of its gas expansion projects.
Projects going online in the fourth quarter were Transco’s Leidy South and Southeastern Trail, along with the Bluestem Pipeline.

“On top of it all this year, our employees followed strict health safety protocols and adhered to local guidance and mandates in order to complete these critical projects amid the risks of the COVID-19 pandemic,” said Alan Armstrong, Williams president and CEO, of the accomplishment.
Leidy South is an expansion of Williams’ existing Pennsylvania energy infrastructure, which brought 125 MMcf/d of capacity online in November with the remaining 457 MMcf/d expected to be complete in 2021.
The expansion connects Appalachia natural gas supplies with growing demand centers along the Atlantic Seaboard.
The Southeastern Trail, is an expansion project, designed to serve growing demand in the Mid-Atlantic and Southeastern U.S. It began partial service of 150 MMcf/d in November and an additional 80 MMcf/d in December.
The balance of the 296 MMcf/d project is expected to come online in the first quarter of 2021.
The Bluestem is a 120 MMbpd NGL transportation pipeline that provides improved market access for mixed NGLs. It was completed under budget and began service in December, two months ahead of schedule.
