Leidy South project online early to provide winter heating capacity

Kasey St. John

Facilities associated with Leidy South, an expansion of Williams’ existing Pennsylvania clean energy infrastructure, were placed into service in November 2020, a full year early, just in time for winter weather.

“Our utility customers are certainly benefiting from the 125 million dekatherm per day (MDth/d) of capacity that was delivered earlier than we expected,” said Robert Biffle, manager, Commercial Services. “This new infrastructure provided an outlet for producers’ natural gas to get to premium markets ahead of the winter season.”

Another 457.4 MDth/d is expected to be complete this year. Combined, that’s enough to heat 2.5 million homes.

The Leidy South expansion connects clean and abundant Appalachia natural gas supplies with growing demand centers along the Atlantic Seaboard.

Recently, the project received a license agreement from the Pennsylvania Department of Conservation and Natural Resources (DCNR) and the notice to proceed from the Federal Energy Regulatory Commission on the last section of pipeline looping.

Completing projects early demonstrates our commitment as safety-driven, reliable performers – delivering on our promises to help our customers achieve their business goals and to bring clean, affordable natural gas to consumers, Biffle said.
