Southeast Supply Enhancement

Overview

The proposed project is an expansion of the existing Transco pipeline’s capacity in the southeastern United States. The project will include pipeline looping adjacent to the existing Transco corridor and modifications to 8 facilities. This expansion will provide reliable natural gas deliveries to Virginia, the Carolinas, Georgia and Alabama to meet the growing residential, commercial and industrial demand in cities across the Mid-Atlantic and Southeast. This project will be regulated by the Federal Energy Regulatory Commission (FERC) under the 7(c) application filing process to ensure thorough consultation and cooperation with other state, local and federal regulatory agencies, and community stakeholders. Once approved by FERC, the expansion project will add approximately 1,587 thousand dekatherms per day (Mdt/d) of pipeline capacity to the Transco system by the fourth quarter of 2027. That is enough affordable, reliable natural gas to meet the needs of 8.6 million homes.

Background

Williams operates the Transco pipeline, an approximately 10,000-mile natural gas transportation system that extends from south Texas to New York City. The Transco pipeline is the nation’s largest-volume natural gas pipeline system, transporting about one-third of the natural gas consumed in the United States.
