(P&GJ) — Enstor Pipeline Holdings has agreed to acquire Black Bear Transmission from funds advised by Basalt Infrastructure Partners, the companies announced on Aug. 19. The deal is expected to close in the fourth quarter of 2025, pending regulatory approvals.
Black Bear operates nine regulated natural gas transmission systems across the Southeast, spanning about 1,700 miles of pipeline with 2.6 Bcf/d of throughput capacity. The systems connect with 16 major long-haul pipelines and storage facilities across Alabama, Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Tennessee.
Enstor, one of the largest privately owned natural gas storage operators in the U.S., runs six underground storage facilities and about 170 miles of pipeline with more than 5 Bcf/d of throughput capacity. After the acquisition, Enstor will oversee more than 1,800 miles of transmission pipeline and 110 Bcf of working gas capacity.
“We are extremely excited to acquire Black Bear, a highly complementary addition to Enstor’s platform that enhances operational efficiencies and supports our long-term growth strategy,” said Enstor CEO Paul Bieniawski. “The Black Bear system is contracted with investment-grade counterparties, which complements Enstor’s existing contract portfolio, and represents a strategic downstream expansion.”
Basalt acquired Black Bear in 2019. “Black Bear Transmission has achieved exceptional organic and inorganic growth since our acquisition,” said David Greenblatt, managing partner at Basalt. “Today, the Company is recognized as a leading supplier of natural gas across the Southeast.”
Financial terms of the transaction were not disclosed. TD Securities is advising Enstor, while Citigroup is advising Basalt.
