Black Bear Transmission

What Black Bear Transmission does

Black Bear Transmission LLC is a Houston-based natural gas transmission company that operates a portfolio of regulated interstate and intrastate pipelines serving utilities, power generators, and industrial end-users across the Southeast United States. As of the August 2025 acquisition announcement, the platform comprised nine regulated transmission systems spanning approximately 1,700 miles with total delivery capacity of more than 2.6 Bcf/d, interconnected with 16 major long-haul pipelines and storage facilities across Alabama, Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Tennessee. Core product systems include the FERC-regulated AlaTenn (325 miles) and Ozark Gas Transmission (368 miles), as well as Trigas, Bamagas, Midla, MLGT, Trans-Union, and ALMS Holdings.

The company earns revenue through regulated firm transportation (FT) agreements that are long-term, take-or-pay style contracts negotiated by an in-house commercial team with investment-grade counterparties including the Tennessee Valley Authority, Arkansas Oklahoma Gas, Arkansas Electric Cooperative Corporation, and Black Hills Energy. Pricing is governed by regulated tariffs rather than market-based disclosure, and contracts include multi-year commitments such as a 15-year transportation agreement signed with TVA in 2021 to support new pipeline facilities. The commercial motion is sales-led and direct, with a Senior Vice President and Chief Commercial Officer leading negotiations; there are no indirect channels or resellers.

Black Bear was established in December 2019 when Basalt Infrastructure Partners acquired Third Coast Midstream's natural gas transmission business, subsequently expanding through the April 2020 acquisition of Ozark Gas Transmission from Enbridge and the September 2020 bolt-on of NGT assets from Third Coast Midstream, while simultaneously divesting non-core gathering assets in 2020, 2021, and 2023 to refocus on transmission. In August 2025, Enstor Pipeline Holdings (affiliate of Enstor Gas) signed a definitive agreement to acquire Black Bear from Basalt, and the transaction completed in November 2025, creating a combined platform with more than 1,800 miles of transmission pipeline and six underground natural gas storage facilities.
