Boardwalk Pipelines

What Boardwalk Pipelines does

Boardwalk Pipelines, LP is a privately held, wholly-owned subsidiary of Loews Corporation (NYSE: L) that operates one of the largest integrated interstate natural gas pipeline networks in the United States. The company is organized around two core operating subsidiaries: Texas Gas Transmission, LLC, which operates approximately 6,000 miles of bi-directional pipeline and nine storage fields with ~84.3 Bcf of working gas capacity across Indiana and Kentucky; and Gulf South Pipeline Company, LLC, which operates approximately 7,260 miles of pipeline with eight salt-dome storage caverns (~29.6 Bcf) and two reservoir fields (~91.5 Bcf) across Mississippi and Louisiana. Combined infrastructure totals ~13,200+ miles of pipeline and ~205 Bcf of working gas storage, with Q1 2026 average daily throughput of approximately 10.1 Bcf/day (6.8 Bcf/d Gulf South + 3.3 Bcf/d Texas Gas) and peak day delivery capacity exceeding 17 Bcf/day across the two systems.

The underlying technology consists of interstate pipeline transmission infrastructure with compressor stations, underground storage facilities, and real-time monitoring systems operating under a comprehensive Pipeline Safety Management System (PSMS). Bi-directional flow capability, enhanced hourly flow services, extra nomination cycles, and seasonal delivery options form the operational backbone. The company is pursuing multiple FERC-licensed expansion projects (Texas Gateway, Kosci Junction, Borealis, Carnation, Dearborn County Lateral, SECURE, PLUSS, Eunice Reliability) designed to add incremental capacity ranging from 236,000 Dth/d up to 1.8 Bcf/d.

Revenue is generated primarily through FERC-regulated tariffs under long-term firm transportation and storage service agreements with utilities, local distribution companies (LDCs), gas-fired power generators, industrial users, LNG export facilities, and natural gas producers/marketers. Storage offerings include firm, interruptible, no-notice, pooling, and swing capacity. Following the April 2026 acquisition of Spire Marketing for $215 million (rebranded Boardwalk Continuum Marketing, LLC), the company has added gas marketing and trading capabilities, enabling bundled supply, transportation, and storage solutions to LNG export and gas-fired power generation end-markets. Go-to-market is enterprise B2B field sales with major energy customers and shippers, supplemented by the Perryville Exchange market hub in north Louisiana. Q1 2026 segment earnings contribution to Loews Corporation was $159 million, up 4.7% year-over-year.
