AltaGas is a North American energy infrastructure company based in Calgary, Alberta. The company operates in three business segments: Utilities, Midstream, and Power.


AltaGas began operations in Calgary in 1994 in the natural gas business, with the goal of building a western Canadian midstream business. The company later began its utility segment in 1998 in Alberta, and entered the power business in 2001.

In 2017 AltaGas agreed to purchase WGL Holdings, significantly expanding its presence in the United States.[2]



AltaGas operates regulated utilities that store and deliver natural gas to end-users across North America. The utility businesses serve approximately 1.8 million customers.


The Midstream segment serves customers primarily in the Western Canadian Sedimentary Basin and transacts more than 2 Bcf/d of natural gas. The division serves many purposes including natural gas gathering and processing, natural gas liquids extraction and separation, transmission pipelines delivery for both gas and liquids, storage and marketing.


AltaGas generates and sells electricity through both natural gas power plants and renewable sources, with a total capacity of 1,708 megawatts. The company also owns 20MW of battery storage in Pomona, California.
