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 1.6 million residential, commercial and industrial customers in four jurisdictions in the U.S.: the District of Columbia (D.C.), Maryland, Virginia and Michigan. The Utilities business also comprises interests in natural gas storage facilities.

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 three states and the District of Columbia, we are developing an integrated footprint capable of delivering sustained value to shareholders and customers alike.
