Explore our historical charts to take a closer look at Xcel Energy-Colorado’s rate trends over the past decade. The charts are based on the average rates paid by residential customers from January 2013 to 2023 and show individual line-item charges on a monthly basis over the same time period. The fixed monthly charge is presented as a cents per kilowatt charge and is calculated by dividing by average customer usage over the year. The charts also reflect preset seasonal changes in rates with summer prices being slightly higher than winter charges.

Xcel Energy-Colorado residential customers have access to both electricity and natural gas rates that are notably below costs seen nationally for each of the past 10 years.
We are committed to delivering clean, reliable, affordable power today and for years to come. Many factors – including fuel costs, environmental regulations, infrastructure improvements and changing energy demand – affect the cost of producing electricity, and, in turn, the price you pay.
