Overview of AltaGas

We are a North American energy infrastructure company with a focus on owning and operating assets that provide clean and affordable energy to our customers. 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


We transact more than 1.5 Bcf/d of natural gas, including natural gas gathering and processing, natural gas liquids (NGL) extraction and fractionation, transmission, storage, natural gas and NGL marketing. We provide producers with an opportunity to move natural gas and NGLs to premium overseas markets through the Ridley Island Propane Export Terminal, and through our ownership interest in Petrogas and the Ferndale Terminal. We also have investments in natural gas pipelines, both in operation and under development, in Canada and the U.S.


We deliver clean and affordable natural gas to approximately 1.6 million customers’ homes and businesses’ through regulated natural gas distribution utilities across five jurisdictions in the United States, and two regulated natural gas storage utilities in the United States.

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 five states, we are developing an integrated footprint capable of delivering sustained value to shareholders and customers alike.
