Description
As at 31 December 2025
FERC-regulated interstate system held alongside Columbia Gas with GIP. A 2023 uncontested rate settlement set new recourse rates effective March 1, 2024 with a moratorium through February 28, 2027 and a new rate filing required by March 1, 2029. The East Lateral XPress expansion connecting supply to Gulf Coast LNG export markets entered service in May 2025 (US$0.3 billion). The Pulaski and Maysville mainline extensions (US$0.8 billion, 0.2 Bcf/d for full coal-to-gas conversion at two power plants) target 2029 service.
