What Gulf South Pipeline does
Gulf South Pipeline Company, LLC is a regulated interstate natural gas transportation and storage operator headquartered in Houston, Texas, and a wholly-owned subsidiary of Boardwalk Pipelines, LP (NYSE: BWP). Founded in 1930, the company operates approximately 7,260 miles of interstate pipeline connecting five major shale plays (Barnett, Eagle Ford, Haynesville, SCOOP/STACK, Woodford) and conventional basins in East Texas, Louisiana, and Mississippi to demand centers across Texas, Louisiana, Mississippi, Alabama, and Florida. The system runs an average daily throughput of approximately 6.8 Bcf and can deliver up to 10.9 Bcf on peak days, with access to key market hubs including Perryville Exchange, Henry Hub, Katy, Carthage, Agua Dulce, and Transco Station 85.
The company's physical infrastructure also includes a high-deliverability storage portfolio: eight salt-dome caverns at Petal, Mississippi (~29.6 Bcf of working gas capacity) and two reservoir storage fields at Bistineau, Louisiana, and Jackson, Mississippi (~91.5 Bcf), for a combined ~121.1 Bcf of working capacity. Service offerings span firm, interruptible, and no-notice transportation and storage, plus customizable parking and lending, pooling, swing capacity, enhanced hourly flow, and extra nomination cycles. Customers include local distribution companies (LDCs), natural gas-fired power generators, industrial end-users, LNG export terminals on the Gulf Coast, and producers/marketers transacting at market centers.
Gulf South earns revenue through contract-based, fee-based transportation tariffs (volumetric/usage-based) and recurring storage service agreements negotiated directly with counterparties under FERC oversight. Distribution is via long-term, direct B2B contracts rather than retail channels; the company has no public consumer footprint. Active and proposed capital projects — PLUSS, Kosciusko Junction, SECURE, Texas Gateway, Eunice Reliability/Lake Charles, Carnation, Borealis, and Dearborn County Lateral — reflect a coordinated capacity-buildout strategy targeting power generation, LNG, data center, and industrial demand growth across the Gulf Coast and Southeast.
