Questar Gas Requests Rate Increase

SALT LAKE CITY - Questar Gas is requesting an increase in its Utah natural gas rates. If the request is approved by the Public Service Commission of Utah (PSC), the monthly bill for the typical residential customer will increase by about $2.20 on August 1.

The request is part of the company’s regular gas-cost-adjustment filing to cover costs of buying natural gas for its customers. These costs are passed on to customers with no markup and therefore no impact on the utility’s profits. The “pass-on” adjustments simply enable the company to change rates to reflect changes in gas-supply costs. Questar Gas is required to apply to the PSC for gas-cost rate changes at least twice yearly.

“Our rates are consistently among the lowest in the U.S. and should remain so even after this increase,” said Ron Jibson, president and CEO of Questar Gas. “However, Questar Gas’s rates need to be increased by 3.9 percent to balance the amount of money we collect from customers with what we need to buy gas for them.”

Forecasts are for stable supplies and prices in the near term. However, Jibson cautioned customers that natural gas prices can fluctuate with changes in supply and demand.

“We continue to encourage customers to take steps to save money and energy by reviewing the energy-saving tips and our ThermWise conservation programs on our website, ThermWise.com,” said Jibson.

Another way to cope with higher bills is enrolling in Questar Gas’s Budget Plan, designed to help spread the annual cost of natural gas service evenly throughout the year. Customers can find more Budget Plan information at www.questargas.com.
