Deal Analysis
The Southeast Supply Enhancement Project represents a significant expansion of Transco's natural gas transmission infrastructure in Virginia and North Carolina. With a Certificate of Public Convenience and Necessity (CPCN) secured, Transco is poised to add 1.6 million Dekatherms (Dth) per day of incremental firm transportation capacity to its existing system. This development project underscores the ongoing demand for natural gas transportation in the southeastern United States and highlights Transco's commitment to meeting that demand through strategic infrastructure investments. The project's announcement in 2026 suggests a forward-looking approach to addressing future energy needs in the region.
