AltaGas Ltd.
AltaGas Ltd. was established in 1976 as the Washington Gas Light Company Pension Plan. The plan covers employees of WGL Holdings subsidiaries and sits under the AltaGas corporate structure founded by David W. Cornhill. The plan deploys capital into fixed income and equities to meet long-term pension obligations. AltaGas itself holds full ownership of WGL Holdings, SEMCO Energy, and Ridley Island Propane Export Terminal. It also maintains a 74 percent stake in Petrogas Energy Corp. and a 10 percent interest in the Mountain Valley Pipeline. These holdings span Canada and the United States. The pension reports $798 million in assets. AltaGas operates from Calgary with additional presence in Washington, DC. In March 2026 the company held its Q4 2025 results conference call covering financial performance and midstream updates. The firm participates in the Canadian Association of Petroleum Producers and the Business Council of Canada. AltaGas maintains 100 percent ownership of multiple midstream facilities through direct corporate subsidiaries rather than external fund vehicles. This structure ties pension funding directly to cash flows from owned energy infrastructure assets.
