Questar Corporation's origins date to the 1922 discovery of natural gas in southwestern Wyoming by a predecessor exploration and production company.
The company built a pipeline, completed in 1929, to transport natural gas from Wyoming to Utah. In 1935 various holdings were consolidated under the name Mountain Fuel Supply Company. In the 1980s, we restructured and renamed the company.
In 2010 Questar spun off its high-growth unregulated exploration and production subsidiaries, keeping Wexpro — a unique natural gas-development company — with the corporation.
Today, Questar is a natural gas-focused energy company with three lines of business — retail gas distribution; interstate gas transportation and storage; and gas development and production.
