AltaGas 101

Natural gas supply, NGL demand fundamentals and the demand for clean energy have consistently underpinned our strategy, as well as the infrastructure we develop. The abundant supply of natural gas in North America, driven by new technology that has improved the economics of unconventional gas plays, has been positive news for North American energy consumers and has led to renewed interest in natural gas as an economically priced, clean‑burning fuel. As a result, the use of natural gas for power generation, household, and commercial and industrial uses has increased substantially, providing significant opportunities across our Midstream and Utilities segments.

Midstream

We have established a significant presence for our Midstream segment in Western Canada through our continued investment in natural gas infrastructure, and the development of a western energy hub in northeast British Columbia. Our integrated footprint in the region provides producers with value-added services and the opportunity to move NGLs to premium overseas markets through our cornerstone Midstream asset - the Ridley Island Propane Export Terminal, near Prince Rupert, British Columbia.

We also have investments in natural gas pipelines, both in operation and under development, in Canada and the U.S. and ownership interests in the Ferndale LPG Terminal in the state of Washington, which we hold an interest in through Petrogas and our AltaGas Idemitsu Joint Venture Limited Partnership.

Our capabilities include:

  • Natural gas gathering and processing
  • NGL extraction and fractionation
  • Storage, marketing and transport
  • Propane export to global markets

We serve customers primarily in the Western Canadian Sedimentary Basin and transact more than 1.5 Bcf/d of natural gas. Our gas gathering systems move natural gas from producing wells to processing facilities where impurities and certain hydrocarbon components are removed. The gas is then compressed to meet downstream pipelines’ operating specifications in order to be transported. Meanwhile, our extraction and separation facilities reprocess natural gas to extract and recover ethane and natural gas liquids. We own approximately 1.5 Bcf/d of extraction processing capacity and approximately 0.7 Bcf/d of raw field gas processing capacity.

In the northeastern U.S., our Midstream segment also includes investments in the Mountain Valley Pipeline (currently under construction). 

Utilities

We own and operate utilities that store and deliver safe and reliable natural gas to homes and businesses in the District of Columbia, Virginia, Maryland and Michigan. Our Utilities segment serves approximately 1.7 million residential, commercial and industrial customers. The Utilities are underpinned by regulated returns and regulatory regimes that generally provide stable earnings and cash flows.

The utilities within this segment of our business are:

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.
