Overview of AltaGas

We are a North American energy infrastructure company with a focus on connecting customers and markets to affordable and reliable sources of energy. Our talented team, nearly 3,000 strong, leverages the strength of our assets and expertise along the energy value chain to connect customers with premier energy solutions – from the well sites of upstream producers to the doorsteps of homes and businesses, to new markets around the world.

Our Core Businesses


Our Midstream business is comprised of global export facilities and strategically located processing, fractionation, and logistics infrastructure, as well as hydrocarbon storage in North America that connects North American producers from wellhead to offshore global export and domestic markets. It also includes integrated hydrocarbons handling services comprised of storage, rail logistics, pipeline, transportation services, and wellsite fluids; natural gas and NGL marketing initiatives that support the Midstream infrastructure; and three gas-fired cogeneration plants. Our integrated footprint in the region provides North American producers with value-added services and the opportunity to move LPGs to premium markets in Asia through Ridley Island Propane Export Terminal (RIPET) and the Ferndale Terminal.


Through our regulated natural gas utilities – Washington Gas and SEMCO – we serve approximately 1.7 million residential, commercial and industrial customers in four jurisdictions in the U.S. including the District of Columbia (D.C.), Maryland, Virginia and Michigan. The Utilities business also comprises interests in natural gas storage facilities.

Although no longer core to our strategy, we continue to maintain a small portfolio of power assets including 695 MW of operational gross capacity from natural gas-fired power generation and energy storage assets located in facilities in Alberta, Canada, as well as nine states and the District of Columbia in the United States. The Power business also includes energy efficiency contracting and WGL’s retail power marketing business.

With infrastructure assets in some of the fastest growing energy markets in North America, including prominent positions in the Montney basin and utilities operations in four states, we are developing an integrated footprint capable of delivering sustained value to shareholders and customers alike.
