Colorado Electricity Rates

Updated April 2026Reviewed by ElectricChoice.com’s Editorial Team

Colorado’s average residential electricity rate is 15.5¢/kWh—14% below the national average. Colorado is a regulated market in the middle of the most aggressive clean energy transition in the interior West—targeting 100% clean electricity by 2040—while still generating 26% of its power from coal. Wind power on the eastern plains, a $1.7 billion transmission build-out, mandatory time-of-use rates, and ski-resort grid challenges make Colorado’s energy market unlike any other.

Colorado’s Clean Energy Crossroads

Colorado is in the middle of the most dramatic energy transition in the interior West. The state has committed to 100% clean electricity by 2040—a target set by SB 19-236 and reinforced by executive orders—making it one of the most aggressive clean energy timelines in the United States. Only a handful of states have set earlier deadlines, and none face Colorado’s unique combination of challenges.

Currently, approximately 42% of Colorado’s electricity comes from low-carbon sources: wind provides 27%, solar contributes 12%, and hydroelectric adds 3%. That’s real progress. But the other side of the ledger tells a more complicated story: coal still generates 26% of Colorado’s electricity—one of the highest coal shares among any state with an aggressive clean energy target. Natural gas fills the remaining 27%.

The tension is clear: aggressive clean goals paired with still-significant coal dependence means an expensive and disruptive transition. Every coal megawatt that retires must be replaced with renewables, battery storage, and transmission infrastructure. The Colorado Energy Plan is the blueprint—retiring the Comanche coal plant in Pueblo, adding massive wind and solar capacity across the eastern plains, and building the $1.7 billion Power Pathway transmission line to move that clean energy to Denver and the Front Range.

2040: The Clean Energy Countdown

Colorado’s progress toward its 100% clean electricity target:

42%
2026 — 42% clean Target: 100% by 2040

What’s in the 42%: Wind 27% + Solar 12% + Hydro 3%. The remaining 58% is fossil: Natural Gas 27% + Coal 26% + other 5%. Colorado must eliminate all coal generation and most gas generation in 14 years—while electricity demand grows from data centers, EVs, and population growth along the Front Range.

Wind Power on the Plains

Colorado’s geography creates one of the most productive wind corridors in the continental United States. The eastern Colorado plains—stretching from the Front Range foothills eastward to the Kansas border—are flat, treeless, and relentlessly windy. This terrain makes eastern Colorado ideal for utility-scale wind generation, and the state has capitalized aggressively.

Wind provides 27% of Colorado’s total electricity generation—the single largest clean energy source and tied with natural gas as the leading generation source overall. Wind farms are concentrated in Weld, Logan, Kit Carson, and Prowers counties, where steady plains winds produce capacity factors that rival the best wind sites in Texas and Iowa. Colorado ranks approximately 8th nationally in installed wind capacity.

But wind on the plains creates a fundamental transmission challenge. The wind farms are in eastern Colorado. The people are in Denver, Boulder, Fort Collins, and Colorado Springs—on the other side of the state. Moving power westward across the Continental Divide to the Front Range population centers requires massive transmission infrastructure. That’s the driving force behind the $1.7 billion Power Pathway transmission project, a new high-voltage line designed to carry renewable energy from the eastern plains to the metro area.

The wind buildout has been a major economic driver for rural eastern Colorado. Wind lease payments provide steady income for ranchers and farmers, and wind farm construction and maintenance jobs have revitalized small towns that were losing population. But the transmission costs are real: the Power Pathway project is one of the largest single infrastructure investments in Colorado history, and those costs will flow through to ratepayers over time.

The Coal Retirement Race

Colorado still burns 26% coal—the elephant in the room for a state targeting 100% clean electricity by 2040. While many western states have already moved past coal or never relied on it heavily, Colorado is attempting to eliminate a significant coal fleet in roughly 14 years. The economics, the politics, and the human impact of this transition define much of Colorado’s energy conversation.

The centerpiece of Colorado’s coal retirement story is the Comanche Generating Station in Pueblo—Colorado’s last major coal-fired power plant. The state has committed to retiring Comanche as part of the Colorado Energy Plan, replacing the capacity with a combination of wind, solar, and battery storage. But the transition isn’t free: replacing reliable baseload coal generation with intermittent renewables plus storage plus new transmission lines is the single biggest driver of rate increases in Colorado.

The impact extends beyond electricity. In western Colorado’s North Fork Valley, coal mines that once anchored the local economy—including the Elk Creek and West Elk mines—have closed or are winding down. Mining communities that relied on high-paying coal jobs are facing economic reinvention. Colorado’s response has been the creation of the Office of Just Transition, a state agency specifically designed to help displaced coal workers and affected communities navigate the economic disruption. It’s a model that states like Indiana and other coal-dependent states are watching closely.

Comanche Station: Colorado’s Last Coal Plant

Location: Pueblo, Colorado — southern Front Range

Capacity: ~1,410 MW from two remaining units (Unit 3 is the newer, larger unit at 750 MW)

Status: Committed to retirement under the Colorado Energy Plan. Unit 1 (325 MW) has already been retired. Units 2 and 3 are scheduled for phased retirement.

Community impact: Comanche is one of Pueblo’s largest employers and a major source of property tax revenue for Pueblo County and local school districts. The plant’s closure will reshape the local economy. Colorado’s Office of Just Transition is working with Pueblo on economic diversification strategies, including attracting renewable energy manufacturing and data center development to the region.

Replacement plan: The Colorado Energy Plan calls for replacing Comanche’s capacity with 1,100+ MW of wind, 700+ MW of solar, and 275+ MW of battery storage — spread across multiple sites in eastern and southern Colorado.

Colorado’s Mountain Resort Grid

No other state in the country faces the electricity challenges that come with powering world-class ski resorts at 8,000–12,000 feet of elevation in some of the most rugged terrain in North America. Colorado’s mountain resort communities—Vail, Aspen, Beaver Creek, Steamboat Springs, Glenwood Springs—represent a unique and demanding corner of the state’s electric grid.

The rural electric cooperative serving the Vail Valley through Aspen and down to Glenwood Springs manages a grid unlike any other in Colorado. Its ~60,000 members include some of the highest per-customer electricity consumption in the state. Mountain homes in Aspen and Vail routinely exceed 10,000 square feet, with heated driveways, snowmelt systems embedded in walkways and patios, radiant floor heating, and outdoor hot tubs—all running through long, cold winters. A single large mountain home can consume more electricity than 5–10 average Colorado households.

Ski resorts themselves are massive electricity consumers. Chairlifts, gondolas, snowmaking machines, base lodge operations, and slope lighting at night consume enormous amounts of power. Vail Resorts, which operates Vail, Beaver Creek, Breckenridge, and Keystone in Colorado alone, has committed to a zero net operating footprint by 2030—an ambitious goal given the energy intensity of ski operations.

Aspen: America’s First 100% Renewable City

The City of Aspen achieved 100% renewable electricity in 2015—one of the first cities in the United States to reach that milestone. Aspen’s municipal utility sources power from a combination of hydroelectric (from local dams on the Roaring Fork and Frying Pan rivers), wind power purchase agreements, and a small amount of landfill gas generation.

Aspen’s achievement is impressive but also illustrative of scale challenges: the city has a small year-round population (~7,500) and benefits from historical hydroelectric infrastructure. Replicating Aspen’s model at the scale of Denver or Colorado Springs would require vastly more renewable capacity and storage.

Grid challenges in mountain terrain: The cooperative’s lines cross mountain passes, traverse avalanche paths, and endure extreme winter weather. Power restoration after a major winter storm can take days in remote mountain areas. The cooperative has invested in undergrounding critical lines and building redundant feeds to resort communities, but geography makes mountain grid reliability an ongoing challenge.

Colorado Business Electricity Rates

Colorado’s commercial electricity rate of 12¢/kWh is competitive nationally, and the state’s diverse economy drives electricity demand across a wide range of industries. Denver’s emergence as a major tech and aerospace hub, combined with Colorado’s unique industries, creates a varied commercial electricity landscape.

Tech & Data Centers

Google, Amazon, and Oracle all have significant operations in the Denver–Boulder corridor. Colorado’s growing data center market is drawn by affordable power, cool climate (reducing cooling costs), and a deep tech talent pool from CU Boulder, Colorado School of Mines, and the Denver metro’s growing tech scene. Denver ranks among the top 15 U.S. data center markets.

Typical: 500,000–50,000,000 kWh/mo

Aerospace & Defense

Colorado is the nation’s #2 aerospace economy. Lockheed Martin (Littleton — satellite manufacturing), Ball Aerospace (Boulder — space instruments), United Launch Alliance (Centennial — rocket manufacturing), and dozens of defense contractors cluster around the Denver metro. The U.S. Space Force and NORAD at Peterson and Cheyenne Mountain add military demand.

Typical: 100,000–10,000,000 kWh/mo

Cannabis Cultivation

Legal since 2012, Colorado’s cannabis industry includes hundreds of indoor grow operations that are among the most electricity-intensive businesses per square foot in the state. High-intensity lighting, HVAC, and dehumidification systems drive massive consumption. Denver has implemented special cannabis energy programs and efficiency requirements to manage the grid impact of concentrated grow operations.

Typical: 50,000–2,000,000 kWh/mo

Brewing & Outdoor Recreation

Coors Brewery in Golden operates one of the largest single-site breweries in the world, consuming enormous amounts of electricity and water. Colorado’s broader craft brewing industry (400+ breweries) adds significant commercial electricity demand. The outdoor recreation and tourism economy—ski resorts, national parks (Rocky Mountain, Mesa Verde, Great Sand Dunes, Black Canyon), and mountain tourism—drives seasonal electricity peaks in resort communities statewide.

Why Colorado Hasn’t Deregulated

Unlike Texas, Ohio, or Indiana’s neighbor Illinois, Colorado has never seriously pursued electricity deregulation. The reason is straightforward: the state’s political energy has been focused on the clean energy transition, not competitive markets. With the 100% clean electricity by 2040 mandate consuming the attention of regulators, legislators, and utilities, introducing retail competition would add complexity to an already-challenging transformation.

There is one notable exception: Colorado Springs operates a municipal utility governed by the city council rather than the CPUC. This gives Colorado Springs residents a quasi-competitive model—their rates are set by elected officials directly accountable to voters. It’s not deregulation, but it provides a degree of local control that customers of the state’s dominant investor-owned utility don’t have.

There has been growing interest in community choice aggregation (CCA)—a model where municipalities or counties band together to purchase electricity collectively, potentially from cleaner or cheaper sources than the incumbent utility offers. Several Front Range cities have explored CCA as a way to accelerate clean energy adoption beyond the current utility timeline. However, no major CCA program has launched in Colorado as of 2026.

How to Lower Your Colorado Electricity Bill

Colorado’s new mandatory TOU rates create both challenges and opportunities. The 2.7x multiplier between peak and off-peak rates means small changes in when you use electricity can produce outsized savings. Here are the most effective strategies:

Optimize Around TOU Windows

On-peak hours are 1–7 PM weekdays. Shift laundry, dishwashers, EV charging, and other flexible loads to before 1 PM or after 7 PM to pay 7.88¢ instead of 21.28¢—saving up to 63% per kWh. Pre-cool your home during off-peak morning hours so your AC runs less during peak. Weekends are always off-peak, so batch energy-intensive tasks for Saturday and Sunday.

Go Solar

Colorado averages 300+ sunny days per year, especially along the Front Range and Western Slope. With the 30% federal ITC, typical solar payback periods are 7–9 years. Solar pairs well with TOU rates: panels generate most during midday off-peak hours, and a battery can shift excess production to offset expensive on-peak evening usage. Colorado offers interconnection and net metering for residential solar.

Use Utility Rebates & Programs

Colorado’s utilities offer rebates for high-efficiency HVAC systems, insulation upgrades, smart thermostats, and EV charger installations. A smart thermostat alone can reduce heating/cooling costs by 10–15%. If your usage is concentrated during peak hours and you can’t shift it, consider opting out of TOU for the flat rate (~10¢/kWh)—run the numbers on your specific usage pattern.

Frequently Asked Questions About Colorado Electricity

What is the average electricity rate in Colorado?

Colorado’s average residential electricity rate is 15.5¢/kWh as of April 2026—approximately 14% below the national average of 18.05¢/kWh. Commercial rates average about 12¢/kWh. Rates vary by region across the state. Rates are expected to increase due to the clean energy transition.

Is Colorado a deregulated electricity state?

No. Colorado is a fully regulated electricity market. Your utility is determined by your address, and you cannot choose your electricity provider. The state’s political energy has been focused on clean energy mandates (100% clean by 2040) rather than retail competition. Colorado Springs operates a municipal utility with local governance, and there is growing interest in community choice aggregation (CCA), but full deregulation has not been pursued. For electricity choice, you’d need to be in a state like Texas or Ohio.

What are Colorado’s Time-of-Use rates?

Time-of-Use (TOU) rates became the default for Colorado residential customers in November 2025. Summer rates (June–September): on-peak 21.28¢/kWh (1–7 PM weekdays) vs off-peak 7.88¢/kWh—a 2.7x multiplier. Non-summer rates: on-peak 18.33¢ vs off-peak 6.79¢. Weekends and holidays are always off-peak. Customers can opt out to a flat rate of approximately 10¢/kWh, but the off-peak TOU rate is significantly cheaper for those who can shift usage away from the 1–7 PM window.

What is Colorado’s clean energy goal?

Colorado targets 100% clean electricity by 2040, established by SB 19-236 and reinforced by executive orders. As of 2026, approximately 42% of generation comes from low-carbon sources: wind (27%), solar (12%), and hydro (3%). The remaining 58% is fossil fuels—natural gas (27%) and coal (26%). Reaching the 2040 target requires eliminating all coal generation, most gas generation, and building massive new renewable capacity and battery storage—all while demand grows from EVs, data centers, and population growth.

Why are Colorado electricity rates increasing?

Colorado electricity rates are rising primarily due to the cost of the clean energy transition. Retiring coal plants (particularly Comanche in Pueblo) and replacing them with wind, solar, and battery storage requires billions in capital investment. The $1.7 billion Power Pathway transmission project to move renewable energy from eastern Colorado to the Front Range adds further cost. A 9.93% residential rate increase has been proposed for August 2026 (~$9.94/month for the average residential customer). Grid modernization, wildfire mitigation, and storm hardening also contribute to rising costs.

What happened to Comanche coal plant?

Comanche Generating Station in Pueblo is Colorado’s last major coal-fired power plant. The plant is being retired under the Colorado Energy Plan. Unit 1 (325 MW) has already been retired, and Units 2 and 3 are scheduled for phased retirement. The plant’s closure has significant implications for Pueblo—Comanche is a major employer and tax revenue source—and Colorado’s Office of Just Transition is working with the community on economic diversification. Replacement capacity will come from 1,100+ MW of wind, 700+ MW of solar, and 275+ MW of battery storage.

Is solar worth it in Colorado?

Yes. Colorado averages 300+ sunny days per year, making it one of the better solar markets in the country. With the 30% federal Investment Tax Credit and state rebates, typical payback periods are 7–9 years. Colorado’s new TOU rates make solar even more attractive—panels generate most during midday off-peak hours, and a battery system can shift excess production to offset expensive on-peak evening usage (21.28¢/kWh in summer). Front Range and Western Slope locations get the best solar resource.

What is the average monthly electric bill in Colorado?

The average monthly electric bill in Colorado is approximately $110—lower than the national average. Colorado’s relatively dry climate, moderate summers (less air conditioning than Sun Belt states like Arizona), and below-average rates all contribute to lower bills. However, bills vary significantly: mountain resort communities with heated driveways and snowmelt systems can see monthly bills of $300–500+, while efficient Front Range homes in mild months may pay $70–90.
