Core offering

Iroquois Gas Transmission System, L.P. operates a 414-mile FERC-regulated interstate natural gas transmission pipeline running from the U.S.-Canada border near Waddington, NY to South Commack (Long Island) and Hunts Point (Bronx), NY. The partnership sells firm and interruptible natural gas transportation services under FERC tariffs to enterprise shippers — local gas distribution companies, electric utilities, electric power generators, and natural gas marketers. Supporting the pipeline are 24/7 gas control operations, the IroquoisOnLine electronic shipper platform, and ongoing compression-based capacity expansion projects.

Product overview

Iroquois Gas Transmission System operates as a unified interstate natural gas transmission platform serving the Northeast, consisting of a 414-mile pipeline system with integrated service modules. The core product is the pipeline infrastructure delivering natural gas to utilities, power plants, and industrial users. Supporting this are electronic service platforms including IroquoisOnLine for shipper transactions, Gas Control & Scheduling for 24/7 operations monitoring, Commercial Services for marketing and contracting, and Prospective Shipper Services for account onboarding. Expansion capabilities are provided through the Enhancement by Compression (ExC) and Wright Interconnect Project (WIP) initiatives. An interactive pipeline map provides geographic visualization of the system and interconnects.

Direct peers

• Enbridge Inc. Enbridge owns and operates Algonquin Gas Transmission and Maritimes & Northeast Pipeline, which are FERC-regulated interstate natural gas transmission systems serving the U.S. Northeast. Both pipelines directly compete for the same New York and New England LDC, utility, and power-generation shippers as Iroquois, and use similar capacity-leasing and FERC-tariff commercial structures. Paul Amato, Iroquois' incoming SVP Operations, previously worked at Algonquin Gas Transmission.
• Kinder Morgan Inc. Kinder Morgan operates the Tennessee Gas Pipeline and Texas Eastern Transmission, two large FERC-regulated interstate natural gas transmission systems in the northeastern U.S. They share Iroquois' business model (FERC-tariffed shipper transportation, compression stations, scheduled nominations) and serve overlapping customers such as LDCs and gas-fired power generators.
• Williams Companies Inc. Williams operates the Transcontinental Gas Pipe Line (Transco), a FERC-regulated interstate natural gas transmission system delivering gas from the Gulf Coast and Marcellus to the Northeastern U.S., including the New York City metro. Transco's Northeast Laterals directly compete with Iroquois for New York and New Jersey distribution and power-generation markets, using nearly identical commercial and operational practices.
• National Fuel Gas Company: National Fuel Gas Supply Corporation is a FERC-regulated interstate natural gas pipeline serving Pennsylvania and New York, including markets that overlap with Iroquois' Northeast footprint. Its Appalachian/Marcellus sourcing and FERC-tariffed transportation service are directly comparable to Iroquois' transmission operations and customer set.
• Equitrans Midstream Corporation: Equitrans operates the Equitrans Pipeline (formerly Equitrans Gathering) and a major stake in the Mountain Valley Pipeline, both FERC-regulated natural gas transmission systems moving Marcellus production to the Northeast. They share Iroquois' Appalachian-supply-to-Northeast-market orientation and rely on FERC-tariffed services.
• Boardwalk Pipeline Partners (Boardwalk Pipelines): Boardwalk Pipelines operates FERC-regulated interstate natural gas transmission systems (Texas Gas Transmission, Gulf South Pipeline, and Boardwalk Louisiana Midstream) delivering gas across the U.S. It uses the same FERC tariff model, shipper transportation contracts, and expansion-by-compression playbook that Iroquois applies to its Northeast pipeline.

Broad incumbents

• TC Energy Corporation: TC Energy is the parent-owner of Iroquois and also operates Columbia Gas Transmission, ANR Pipeline, and other FERC-regulated U.S. interstate natural gas pipelines. The overlap in service territory (Northeast U.S.), FERC regulatory model, and compression-driven expansion playbook make TC Energy's pipeline segment Iroquois' closest broad-incumbent peer.
• Dominion Energy (now Berkshire Hathaway Energy): Berkshire Hathaway Energy, Iroquois' co-owner, also controls Dominion Energy's natural gas transmission and storage business, including the Cove Point LNG facility. Dominion's interstate pipeline subsidiary historically served Mid-Atlantic and Northeast gas markets, making it a broad-incumbent peer in the same regulated interstate transmission space.
• Cheniere Energy Partners: Cheniere operates the Sabine Pass and Corpus Christi LNG export terminals, which drive incremental Northeast Marcellus production takeaway and indirectly support demand on Iroquois-style interstate transmission. It is a broader incumbent in the gas value chain rather than a direct operator competing for the same shippers.

Regional players

• Spire Inc. Spire operates the Spire Storage and related FERC-regulated pipeline assets serving the Midwest and Mid-Atlantic. While geographically distinct, its regulated storage and transportation business model and FERC-tariff framework closely mirror Iroquois' interstate transmission operations.
