Denver Electricity Rates
- Denver is served by Xcel Energy — Colorado’s largest utility and a national leader in renewable energy.
- The average residential rate is 15.5¢/kWh — 18% below the national average.
- At 5,280 feet with 300 days of sunshine, Denver is one of the best major cities in the US for rooftop solar.
Why Denver Is a Solar Powerhouse
At 5,280 feet above sea level, Denver’s thin atmosphere filters less sunlight than sea-level cities. Combined with 300 days of sunshine per year and dry air that reduces cloud-related losses, Denver’s solar panels produce 20% more energy than the same panels at sea level.
Denver’s solar advantage isn’t just about sunshine — it’s physics. At altitude, solar irradiance is measurably stronger because there’s less atmosphere absorbing and scattering photons before they hit your panels. The dry climate also means less humidity-related derating. Snow reflection (“albedo effect”) can even boost winter production on clear days when snow is on the ground but not on the panels.
Xcel Energy Residential Rates (2026)
Xcel uses a two-tier seasonal rate: usage above 500 kWh/month costs more per kWh, and summer rates are higher than winter. They also offer an optional time-of-use plan.
Optional: Time-of-Use Rate
Xcel offers a TOU plan with three pricing windows. The on-peak window is 3–7 PM weekdays year-round. EV owners and solar customers benefit most — charge at night, export during the day.
What 775 kWh Actually Costs in Denver
Denver homes use less electricity than the national average — about 775 kWh/month vs. 900+ nationally. The dry climate means modest AC loads, and most Denver homes heat with natural gas, keeping electric bills manageable year-round.
Denver Electric Bills
Denver’s bill curve is unusually flat compared to cities in the South and Midwest. Dry air keeps summer AC loads moderate, and gas heating means winter electric bills don’t spike like they do in all-electric homes.
Estimated monthly bill across the year
Bills range from about $100 in Apr to $148 in Jul. The spread is only about $48 peak-to-trough — much flatter than Atlanta ($90+ swing) or Kansas City ($80+ swing). Denver’s “swamp coolers” (evaporative coolers) are common in older homes and use a fraction of the energy of traditional AC.
Colorado Power Generation
Monthly bills are modeled from the local average rate and a semi-arid Front Range seasonal usage profile. Your actual usage will vary — homes with electric heat will see higher winter bills. Grid mix reflects Colorado generation sources (EIA/Xcel data).
Colorado’s Clean Energy Timeline
Colorado has one of the most aggressive clean energy transitions in the country. Xcel Energy’s “Clean Energy Plan” is retiring coal plants and replacing them with wind, solar, and battery storage — and doing it ahead of schedule.
Colorado went from over 60% coal a decade ago to just 17% today — one of the fastest coal-to-renewables transitions of any state. Wind is now the single largest source of electricity in Colorado, and solar is growing rapidly thanks to Denver’s excellent solar resource and falling panel costs.
Solar in Denver
Denver’s altitude + sunshine combination makes it one of the top 10 U.S. cities for residential solar. At 5.5 peak sun hours/day and a 20% altitude boost over sea level, a typical system produces significantly more than the national average.
Denver solar considerations: Xcel Energy offers net metering where exported kWh are credited at the full retail rate. Colorado’s renewable energy standard also supports solar with a distributed generation carve-out. One unique Denver factor: hail — the Front Range is one of the most hail-prone areas in the US. Modern panels are rated for 1-inch hail at 50 mph, but severe Denver hailstorms can exceed that. Check your homeowner’s insurance coverage before installing.
Estimate assumes a 7 kW system at $2.65/watt, an 82% performance ratio (above average due to altitude and dry air). Colorado does not currently offer a state solar tax credit, but some local rebates may apply through Xcel’s Solar*Rewards program.
Denver Utilities
Denver is served exclusively by Xcel Energy. Colorado is a regulated market — you cannot choose your electricity provider. However, Denver has been exploring municipal utility options for years.
Xcel Energy is a Minneapolis-based utility operating in eight states. In Colorado, it serves the entire Front Range corridor from Fort Collins to Pueblo, including Denver, Boulder, Colorado Springs, and Aurora. Xcel has committed to 100% carbon-free electricity by 2040 — one of the most aggressive targets among major US utilities. The company has retired multiple coal plants ahead of schedule, replacing them with some of the largest wind and solar farms in the Midwest.
Municipal utility debate: Denver voters have considered creating a city-owned utility multiple times (most recently in 2023), arguing it would accelerate the clean energy transition and give Denver more control over rates. So far, the city has opted to work with Xcel through a franchise agreement, but the debate continues as Denver pursues its goal of 100% renewable electricity by 2030.
Denver Electricity FAQ
Common questions about electricity rates, utilities, and service in Denver and the Front Range.
What is the average electricity rate in Denver?
Denver’s average residential rate is 15.5¢/kWh as of October 2026 — approximately 18% below the national average of 18.83¢/kWh. Xcel uses a two-tier seasonal structure: summer Tier 2 (above 500 kWh) is the most expensive at 17.8¢/kWh.
Who is the electric utility for Denver?
Xcel Energy (operating as Public Service Company of Colorado) is the sole electric utility for Denver and most of the Front Range. Colorado is a regulated market — your utility is determined by your address. Rates are set by the Colorado Public Utilities Commission. Outages: 1-800-895-1999.
Why are Denver electric bills relatively low?
Several factors: Denver’s semi-arid climate means low humidity and relatively mild summers compared to the South — AC loads are moderate. Most Denver homes heat with natural gas, so winter electric bills don’t spike. Average usage is about 775 kWh/month, well below the national average of 900+ kWh. Combine lower usage with below-average rates and you get monthly bills around $120.
How clean is Denver’s electricity?
Colorado’s grid is now 51% renewable — wind alone provides 30% of generation. A decade ago, coal was over 60%; it’s now down to 17% and falling. Xcel has committed to 100% carbon-free electricity by 2040, and Colorado’s grid is one of the fastest-decarbonizing in the nation.
Is solar worth it in Denver?
Denver is one of the best cities in the US for rooftop solar. With 5.5 peak sun hours/day (boosted by altitude) and Xcel’s net metering, a 7 kW system saves about $1,786/year and pays for itself in roughly 10.4 years. One caveat: hail — Denver’s Front Range location makes it hail-prone. Modern panels handle most hail, but verify your insurance covers solar equipment.
Does Denver have evaporative (swamp) coolers?
Yes — Denver’s dry climate makes evaporative coolers effective from roughly May through mid-August. They use 75% less electricity than traditional AC. As humidity levels have risen slightly in recent decades, some homeowners are adding supplemental mini-split AC for the most humid weeks. If you have a swamp cooler, your summer electric bills will be significantly lower than the estimates shown above.
How do I report a power outage in Denver?
Contact Xcel Energy at 1-800-895-1999 or report online at xcelenergy.com. Xcel’s outage map provides real-time restoration estimates for the Denver metro area and the entire Front Range.
