Boardwalk Pipeline operates approximately 14,000 miles of interstate natural gas pipelines and around 40 underground storage fields across the US Gulf Coast, Southeast, Midwest and Northeast — making it one of North America’s largest dedicated natural gas transmission networks. Wholly owned by Loews Corporation (NYSE: L) since a 2018 take-private transaction, Boardwalk Pipeline sits at the centre of growing LNG export feed gas demand on the Gulf Coast and seasonal heating supply for Midwest and Northeast markets.
Boardwalk Pipeline — Company Overview
Boardwalk Pipeline Partners was taken private by Loews Corporation in 2018 when Loews bought out the remaining public unitholders, ending its years as a separately listed MLP. Loews — primarily a holding company with interests in hotels, insurance, and packaging — reports Boardwalk as its largest revenue-generating segment, with the pipeline business contributing approximately $1.6bn in FY2024 revenue.
Headquartered in Houston, Texas, the company is led by CEO Michael Barber. Both core pipeline systems are FERC-regulated interstate natural gas assets, with revenues governed by tariff structures and rate cases filed with the Federal Energy Regulatory Commission. The business is a pure-play natural gas operator — no crude oil, no NGL focus.
Gulf South Pipeline — Boardwalk’s Gulf Coast Artery
Gulf South Pipeline spans approximately 7,000 miles across the Gulf Coast, Southeast US, and into Midwest markets. The system draws on Gulf of Mexico offshore production and onshore Gulf Coast gas supply, positioning it directly in the path of growing LNG export feed gas volumes from liquefaction terminals along the Texas and Louisiana coastline.
In 2026, LNG export demand is the primary throughput growth driver on Gulf South. As US LNG export capacity has expanded, feed gas volumes moving through Gulf Coast pipeline infrastructure have risen materially. Southeast power generation load — partly driven by data centre electricity demand concentrated in states like Georgia, Virginia, and the Carolinas — is adding incremental gas demand to the same corridors Gulf South serves.
Texas Gas Transmission — Midwest and Northeast Supply
Texas Gas Transmission covers approximately 6,000 miles from the Gulf Coast production regions northward through the Midwest into the Northeast US. The system is a key winter supply artery, moving gas into markets with high residential and commercial heating demand during peak periods.
Texas Gas Transmission operates in corridors where winter capacity utilisation and storage drawdown are primary seasonal revenue drivers. While Williams Companies’ Transco pipeline runs a north-south corridor from the Gulf to New York City, Texas Gas serves complementary Midwest and Northeast markets — the two systems overlap in geography of end-markets served rather than directly competing on the same trunk routes.
Underground Storage — 200 Bcf Working Capacity
Boardwalk Pipeline holds approximately 200 Bcf of working gas storage capacity across around 40 underground storage fields. These are predominantly depleted reservoir and aquifer storage facilities, geographically distributed to serve both Gulf South and Texas Gas Transmission markets.
Storage revenue contributes meaningfully alongside transportation tariffs. Customers contract for storage capacity to manage seasonal demand swings — injecting gas during summer months when demand is lower, withdrawing during winter peak periods. Under FERC rate regulation, Boardwalk’s storage rates are governed by the same tariff and rate case structures as its transportation services.
2026 Strategy and Market Drivers
LNG export demand growth is the most significant structural tailwind for the Gulf South system in 2026. As new US LNG export capacity ramps — including projects along the Texas and Louisiana Gulf Coast — feed gas transportation requirements on interconnected pipeline systems like Gulf South increase. This is a multi-year demand driver, not a short-term event.
Southeast power generation gas demand, amplified by data centre load growth in the region, is creating additional incremental throughput. On the storage side, winter peak utilisation on the Texas Gas system remains the key seasonal variable. FERC rate case outcomes continue to govern the revenue ceiling on both systems — rate cases are a recurring feature of Boardwalk’s regulatory calendar rather than a one-off risk event. Loews’ capital allocation decisions, balancing Boardwalk investment against other group priorities, shape the pace of any network expansion.
Boardwalk Pipeline in the North American Gas Market
Boardwalk Pipeline is a natural gas pure-play in a midstream sector dominated by companies with diversified crude oil, NGL, and gathering operations. Peers including Kinder Morgan — operator of the El Paso and Tennessee gas transmission systems — and Energy Transfer operate far larger and more commoditised midstream networks. Boardwalk’s approximately 14,000-mile footprint and 200 Bcf storage base give it regional scale, but its geographic concentration in Gulf Coast-to-Midwest and Gulf Coast-to-Southeast corridors distinguishes it from transcontinental systems.
For a broader view of where Boardwalk sits among the top pipeline companies globally, or specifically within the top US midstream operators, the competitive landscape is defined by system scale, commodity mix, and geographic reach — all areas where Boardwalk’s natural gas focus and regional corridor position are its defining characteristics.

Who owns Boardwalk Pipeline?
Boardwalk Pipeline is a wholly owned subsidiary of Loews Corporation (NYSE: L). Loews completed a take-private transaction in 2018, buying out the remaining public unitholders of Boardwalk Pipeline Partners. The company no longer trades independently and is reported as a business segment within Loews’ annual results.
What pipelines does Boardwalk Pipeline operate?
Boardwalk Pipeline operates two core FERC-regulated interstate natural gas systems: Gulf South Pipeline, spanning approximately 7,000 miles across the Gulf Coast and Southeast US, and Texas Gas Transmission, covering approximately 6,000 miles from the Gulf Coast into Midwest and Northeast markets.
How much storage capacity does Boardwalk Pipeline have?
Boardwalk Pipeline holds approximately 200 Bcf of working gas storage capacity across around 40 underground storage fields. These facilities serve both systems, providing seasonal storage for winter peak demand cycles across Midwest and Southeast markets.
Where does Boardwalk Pipeline operate?
Gulf South Pipeline serves the Gulf Coast, Southeast US, and Midwest markets, acting as a key conduit for Gulf of Mexico and onshore Gulf Coast gas production including LNG export feed gas. Texas Gas Transmission serves Midwest and Northeast US markets with a focus on residential and commercial heating supply.
How does Boardwalk Pipeline compare to Williams Companies?
Williams Companies’ Transco system runs a north-south corridor from the Gulf Coast to New York City, serving the densely populated US Eastern Seaboard. Boardwalk Pipeline’s Texas Gas Transmission serves Midwest and Northeast markets via a different trunk route, making the two systems more complementary than directly competing. Both are FERC-regulated natural gas pure-plays, though Williams operates at significantly larger scale.
