Company overview

QUESTAR GAS CO

Questar Gas Co. has long been a key natural gas distributor in the Mountain West, delivering reliable energy for residential heating, commercial cooking, and industrial process support across its regulated service territory; its infrastructure-intensive offerings include local distribution mains, metering, and maintenance services tailored to utilities, municipalities, and large commercial energy consumers whose operations depend on consistent gas availability. The company operates within the traditionally utility-focused SIC framework (4924 – Natural Gas Distribution), where oversight from state public service commissions and federal environmental regulators keeps service standards high while exposing Questar to capital-intensive compliance and rate-setting constraints; material risks center on demand fluctuations, pipeline integrity, and the interplay between carbon-reduction mandates and aging assets. Catastrophic weather events or delayed approvals for infrastructure investments could affect reliability and returns, making thoughtful regulatory engagement essential.
