Colorado Natural Gas Files Application for Authorization to Recover the Gas Costs Associated with the February 2021 Extreme Winter Weather Event.

The State of Colorado and the surrounding area experienced an extreme weather event on February 13-17, 2021. Through the efforts of our dedicated team members, we succeeded in delivering safe, reliable natural gas service to our customers to keep their homes warm and businesses running, and none of our customers lost service during the extreme weather event. However, the unusually cold temperatures resulted in record-high customer demand across much of the country, and also took some natural gas production offline, which resulted in an unprecedented spike in natural gas prices across much of the U.S.

While our usual commodity purchasing and storage policies did provide significant price protection for our customers, high fuel costs were still incurred. At the request of the Colorado Public Utilities Commission (CPUC), we and other Colorado utility companies have conducted extensive studies of these high costs and presented our proposal for how and when to recover these costs from customers while limiting the impact to monthly bills.


It’s important to note that Colorado Natural Gas does not make a profit on the natural gas purchased for our customers; the price of natural gas is passed through to customers at cost.


Our proposal is designed to reduce the impact to customers’ bills as much as possible through a separate bill rider spread out over the next 5 years to decrease the monthly amount. Not all Colorado Natural Gas customers were impacted in the same way during the February extreme weather event. If our proposal is approved, the impact on customers’ bills would be based on location as follows:

RATE AREA RESIDENT MONTHLY IMPACT (DOLLARS) RESIDENT BILL INCREASE (PERCENT) COMMERCIAL MONTHLY IMPACT (DOLLARS) COMMERCIAL BILL INCREASE (PERCENT)
Cripple Creek $2.47 2.4% $19.96 2.6%
Bailey/South Park $4.14 3.3% $20.19 3.5%
Pueblo West $3.93 4.4% $22.55 4.8%
Eastern $8.99 14.5% $17.37 14.6%
Eastern Large Commercial - - $796.50 18.6%

Any pricing change must be approved by the CPUC, and our proposal is still under review, and may take several months to come to resolution. Customers will not see any bill changes until 30 days after the conclusion of the proceeding.

February 2021 Cold Weather Event FAQ

How will the extreme cold weather event affect my natural gas bill?

Extraordinary costs occurred when demand increases went beyond sufficient supplies. Our natural gas system succeeded in delivering safe, reliable natural gas service to our customers, but we experienced significant commodity cost increases from our suppliers due to extremely high demand and natural gas production interruptions.

Are the high prices being seen across the country?

Our expert Gas Supply team members were able to limit the impacts to our customers, but all states and the utilities impacted by the winter storms incurred increases in costs related to the significant spike in usage and gas prices.

Does Colorado Natural Gas(CNG) make a profit on the natural gas they purchase for customers?

No. The cost CNG pays for natural gas is passed on to our customers with no mark-ups. Our Gas Supply team plans ahead for extreme winter weather in Colorado; however, the extreme weather event across much of the U.S. in February caused the largest natural gas price increases in the last twenty years.
