- AltaGas Ltd. is a Calgary, Canada-based North American energy infrastructure company engaged primarily in utilities and midstream segments. The company provides franchised, cost-of-service, rate-regulated natural gas distribution and storage utilities through its subsidiaries Washington Gas and SEMCO, serving approximately 1.6 million residential, commercial, and industrial customers in jurisdictions including the District of Columbia, Maryland, Virginia, Michigan, Ohio, Pennsylvania, Delaware, and parts of Canada. AltaGas's midstream segment encompasses natural gas gathering, processing, extraction with a capacity of approximately 1.2 billion cubic feet per day, fractionation, liquids handling, natural gas and natural gas liquids (NGL) marketing, LPG exports and distribution, logistics including trucking and rail terminals, and liquid storage. Additionally, AltaGas operates gas-fired power generation facilities with a capacity of about 508 megawatts primarily in California and Arizona. Its midstream infrastructure includes strategic export facilities such as the Ridley Island Propane Export Terminal and the Ferndale Terminal, supporting connectivity to global markets, particularly in Asia.
Recent major company changes include AltaGas's decision in late 2025 to retain ownership of the Mountain Valley Pipeline (MVP) system, including MVP Mainline, MVP Boost, and MVP Southgate projects, reversing a previous plan to monetize these assets due to favorable expansion prospects. The company also closed a $460 million bought deal equity financing in November 2025 to support growth initiatives. AltaGas entered into long-term commercial agreements with Keyera Corporation in early 2025, leveraging each company's infrastructure for LPG tolling, fractionation, and logistics services to strengthen market connections and cash flow predictability. These strategic partnerships and financing moves underscore AltaGas's focus on expanding midstream capacity, enhancing utility operations, and maintaining stable, long-term investments in critical energy infrastructure.
Founded in 1994, AltaGas operates primarily across North America, with operations in Canada and the United States including significant presence in the Western Canadian Sedimentary Basin, Michigan, and the U.S. mid-Atlantic region. The company focuses on delivering affordable, reliable energy to residential, commercial, and industrial customers through integrated infrastructure and expert energy management services. AltaGas also provides natural gas storage and transportation services, as well as power generation from diverse fuel sources including gas-fired plants. The company’s strategic footprint includes a mix of regulated utility assets and midstream energy logistics, positioning it to connect producers from well sites to global markets efficiently.
AltaGas serves a broad spectrum of customers in the energy value chain from upstream producers to end-users, aiming to provide reliable and economical energy solutions.
