Gas Cost Adjustment

Colorado Quarterly GCA

We adjust natural gas prices quarterly to reflect the market price of the commodity. All of these costs are passed through to you on a dollar-for-dollar basis through our Gas Cost Adjustment that has been approved by the Public Utilities Commission of the State of Colorado. We hope that by providing you this information each quarter, you will be better able to budget and adjust your energy usage. The information provided in the PDF link below shows only the prices that are changing this quarter and the average effect of those changes. It doesn't show the costs that are not changing.

You may also call our customer service regarding your natural gas bill at 1-800-895-4999.

Energy Saving Tip

Set your hot water heater to no higher than 120 degrees Fahrenheit. This isn't just energy smart—it's also safer, since it reduces the likelihood of accidental burns.

Preventing Carbon Monoxide Poisoning

Install carbon monoxide detectors and annually hire a qualified contractor to inspect your home for proper ventilation.
