Ten-Year Rate Trends

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 and show individual line-item charges on a monthly basis.  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.

Power you can rely on

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.

We continuously balance these factors to ensure reliable electricity, cleaner energy and the best price possible for our customers.

How we’re working to keep rates affordable

To make every dollar count, we work to be as efficient and prudent as possible, and to balance affordability in the present with investments for the future.

The largest single component of your bill is fuel costs. Xcel Energy makes no profit on this portion of your bill since it is directly tied to the cost of fuel in today's marketplace. Although we can't control the global factors that affect these costs, we are taking steps to keep costs down (external link) including:

  • Adding more clean energy to the grid, because wind and solar generate electricity without fuel costs.
  • Purchasing and storing natural gas ahead of the winter heating season when prices are lower.
  • Contracting for wholesale natural gas purchases before winter to lock in lower prices.
  • Having a diverse mix of electricity sources that can be used to minimize the effect of natural gas price increases on electric bills. Our wind farms saved customers billions in avoided fuel costs and tax credits across our corporate service area.
  • Optimizing purchasing and using technology to make the company’s operations more efficient.

Break Ground, Not the Law

Always call 811 before digging in your yard to avoid hitting buried gas or electric lines. Not only is it the safe thing to do, but it's the law.
