Leidy South

Energy expansion provides reliability this winter

Staff Reports

Just in time for this winter’s heating season, Williams has fully completed an energy reliability project in the northeast.

The Leidy South expansion helps the existing Transco pipeline system transport an additional 582,400 dekatherms of natural gas supply per day, which is enough to meet the daily needs of approximately 2.5 million homes.

The project began coming online ahead of schedule in sections in 2020 and through 2021. This expansion to Williams’ existing Pennsylvania energy infrastructure allows for additional supplies of abundant Appalachia natural gas supplies to reach growing demand centers along the Atlantic Seaboard for home heating, cooking and electric power generation.

“I applaud our teams for safely completing this important project with an extremely high level of environmental stewardship,” said Glenn Koch, Williams vice president of project execution for transmission. “The success of this project demonstrates our commitment to being good neighbors in the communities where we operate while helping our customers bring clean, affordable and reliable natural gas to consumers.”

By maximizing the use of its existing transmission corridor, Williams was able to minimize the impact on property owners and the environment. Leidy South is part of Transco, the nation’s largest natural gas transmission network which transports about 15 percent of the natural gas consumed in the United States.
