Boulder Electricity Prices
Electricity costs in Boulder, CO have been climbing steadily — and that trend is worth understanding before your next utility bill arrives.
Colorado’s residential electricity rate rose from 13.1 cents per kWh in 2021 to 15.1 cents per kWh in 2024 — an increase of over 15%. Nationally, rates climbed even faster, from 13.7 to 16.5 cents per kWh over the same period.
Solar panel installation in Boulder, CO gives homeowners a way to generate their own electricity and reduce dependence on the grid — helping to insulate your household from future rate increases.

Price of Energy: Colorado vs National Average
Boulder Area Utility Providers
In Boulder, CO, Xcel Energy is the primary electricity provider. Based on 2023 data, Xcel’s residential rate was 14.30¢ per kWh — equal to Colorado’s state average and below the 2023 national average of 16.0¢ per kWh.
Xcel Energy’s rate aligns closely with Colorado’s state average partly due to the region’s diverse energy mix. However, rates have trended upward in recent years, meaning today’s costs likely exceed what the 2023 data reflects.
For Boulder homeowners, solar panel installation can help offset rising electricity costs over time. Generating your own power means relying less on utility rates — providing more predictability in your monthly energy expenses for years ahead.

Colorado Solar Incentives
Boulder homeowners have access to a range of solar incentives in Colorado that can help reduce the upfront cost of going solar.
Depending on your utility provider and household income, you may qualify for rebates on solar panels, battery storage, or both. Xcel Energy — the primary utility serving Boulder — offers several residential programs worth exploring.
Note: the federal residential solar tax credit has been eliminated by the Big Beautiful Bill. State and local incentives still apply. If you consider a solar lease through Palmetto’s LightReach program, Palmetto handles the commercial tax credit and passes the savings through lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Xcel Energy Solar*Rewards Program | Rebate | Xcel Energy offers residential solar customers an upfront rebate of $1 per watt of installed solar capacity, up to $7,000 for a 7 kW system, with pre-approval required before installation. | |
| Xcel Energy Solar*Rewards – Income-Qualified & Disproportionately Impacted Communities (IQDIC) | Rebate | Income-qualified Xcel Energy customers and those in Disproportionately Impacted communities can receive an enhanced solar rebate of $1,000 per kW, up to $10,000 for a 10 kW system. | |
| Xcel Energy Renewable Battery Connect Program | Rebate | Xcel Energy offers residential battery storage rebates of $350 per kW (up to $5,000) for standard customers, or $800 per kW for income-qualified customers, plus $100 annually for up to 5 years for grid participation. | |
| Xcel Energy Public Safety Power Shutoff (PSPS) Battery Rebate | Rebate | Xcel Energy offers up to $10,000 for battery storage installations for medical-dependent customers living in high wildfire risk areas subject to Public Safety Power Shutoffs. | |
| Tesla Powerwall 3 Manufacturer Rebate | Rebate | Tesla offers a $500 per unit rebate on Powerwall 3 installations, up to $1,000 per address (two units), for systems registered by June 30, 2026 and installed by December 31, 2026. | |
| Colorado Residential Energy Upgrade (RENU) Loan Program | Rebate | The Colorado Clean Energy Fund’s RENU Loan Program offers affordable, low-interest financing for homeowners installing solar panels or other clean energy improvements through partnering state credit unions. |
Xcel Energy’s Solar*Rewards Program provides eligible residential customers with an upfront cash rebate of $1 per watt of installed solar capacity, up to a maximum of $7,000 for a 7 kW system. For a typical 5 kW residential solar installation, this translates to a $5,000 rebate that directly offsets the cost of going solar. Pre-approval from Xcel Energy is required before installation begins, and a $100 filing fee applies for Level 1 systems.
In addition to the upfront rebate, Solar*Rewards participants can receive ongoing monthly payments in exchange for Renewable Energy Credits (RECs) generated by their system. For systems under 25 kW, the performance-based incentive is $0.005 per kWh produced. While modest, this provides a small ongoing income stream over the life of the system.
This program is available exclusively to Xcel Energy residential customers in Colorado. Residents of Boulder served by Xcel Energy are eligible for this program. Because funding is limited and awarded on a first-come, first-served basis, early application is strongly recommended. Contact Xcel Energy or visit their website to check current funding availability and begin the pre-approval process before contracting with an installer.
Xcel Energy’s Solar*Rewards Income-Qualified and Disproportionately Impacted Communities (IQDIC) program offers a significantly enhanced rebate for eligible customers. Qualifying homeowners can receive $1,000 per kilowatt (kW) of installed solar capacity, up to a maximum of $10,000 for a 10 kW system. This is ten times the standard Solar*Rewards rebate rate, making solar dramatically more affordable for lower-income households and those in designated disproportionately impacted communities.
To qualify, customers must be served by Xcel Energy and meet income qualification thresholds or reside in a Colorado-designated Disproportionately Impacted (DI) community. Income qualification is generally based on household income relative to the Area Median Income (AMI) for your county. Xcel Energy can help determine eligibility during the application process.
As with the standard Solar*Rewards program, pre-approval is required before installation, and funding is limited and awarded on a first-come, first-served basis. This program historically fills quickly, so eligible customers in Boulder should apply as early as possible. Visit Xcel Energy’s website or call their renewable energy team to check current funding availability and begin your application.
Xcel Energy’s Renewable Battery Connect Program provides upfront cash rebates to residential customers who install qualifying battery storage systems. Standard customers receive $350 per kW of battery capacity, up to a maximum of $5,000 per application. Income-qualified customers and those residing in Disproportionately Impacted (DI) communities receive an enhanced rebate of $800 per kW, up to 75% of the equipment-only cost. Eligible battery models include the Tesla Powerwall 2, Tesla Powerwall+, Tesla Powerwall 3, and SolarEdge Home Battery.
In addition to the upfront rebate, enrolled customers receive $100 annually for up to five years in exchange for allowing Xcel Energy to dispatch stored energy back to the grid during peak demand events. This brings the total potential benefit to $5,500 for standard customers over the full enrollment period.
Program Status (2026): The 2025 program budget was fully exhausted and the current funding cycle closed in February 2026. Xcel Energy has indicated the program may reopen with new funding mid-year 2026. Interested customers in Boulder should monitor Xcel’s website for updates on funding availability before proceeding with installation.
Xcel Energy’s Public Safety Power Shutoff (PSPS) Battery Rebate provides up to $10,000 for qualifying customers who install a home battery storage system. This program is specifically designed to protect vulnerable customers who depend on electricity for life-sustaining medical equipment and who live in areas prone to Public Safety Power Shutoffs due to high wildfire risk.
To qualify, homeowners must be enrolled in Xcel Energy’s Medical Certification Program or the Colorado Medical Exception Program, and must reside in a Tier 2 or Tier 3 wildfire risk zone within Xcel’s Colorado service territory. The battery storage system must meet Xcel’s technical requirements for the program.
This rebate can be combined with other Xcel battery incentives where applicable, and may significantly offset the cost of a battery system for eligible customers in Boulder. Contact Xcel Energy directly to confirm your eligibility, verify your wildfire risk tier, and begin the application process before purchasing or installing a battery system.
Tesla’s Powerwall 3 Rebate Program (also referred to as the “Next Million Powerwall 3 Rebate Program”) offers homeowners $500 back per Powerwall 3 unit installed, covering both the Powerwall 3 and Powerwall 3 Expansion units. The maximum rebate is $1,000 per address (two units). This is a manufacturer-direct rebate offered by Tesla, not a government or utility program.
To qualify, the sale must be finalized and the rebate registered by June 30, 2026, and the installation must be completed by December 31, 2026. Missing either deadline will disqualify the system from receiving the rebate, so it is important to plan your purchase and installation timeline carefully.
This rebate can be combined with Colorado’s 10% Residential Energy Storage Tax Credit, and — where applicable — with utility battery rebates such as Xcel Energy’s Renewable Battery Connect Program (when funding is available). Stacking multiple incentives can significantly reduce the net cost of a Powerwall 3 installation in Boulder.
The Colorado Residential Energy Upgrade (RENU) Loan Program, offered through the Colorado Clean Energy Fund in partnership with state credit unions, provides affordable financing for homeowners who want to install solar panels or make other clean energy improvements. The program is designed to make the upfront cost of solar more manageable by offering competitive interest rates and flexible repayment terms that are often more favorable than traditional home improvement loans.
The RENU Loan is available to Colorado homeowners and can be used to finance solar panel systems, battery storage, and other qualifying clean energy upgrades. Because the loan is administered through local credit unions, borrowers benefit from working with community-based lenders who are familiar with Colorado’s clean energy landscape.
To apply, homeowners in Boulder should visit the Colorado Clean Energy Fund’s website to find a participating credit union and begin the application process. Using a RENU Loan in combination with available rebates and tax credits can help homeowners go solar with little to no money out of pocket, with loan payments often offset by monthly electricity bill savings.

Leasing Solar Panels
If you’re not ready to pay for solar panels upfront, a Power Purchase Agreement (PPA) may be a good fit. In Colorado, Palmetto offers PPAs through major utility providers — including Xcel Energy, United Power, Black Hills Energy, Colorado Springs Utilities, CORE Electric Cooperative, Grand Valley Power Cooperative, and DMEA. That means most Boulder-area homeowners served by Xcel Energy are eligible.
With a solar PPA, you don’t own the system — Palmetto does. Instead of a fixed monthly payment, you pay for the electricity your panels produce at a set rate per kilowatt-hour (kWh). Your bill will be slightly higher in summer when panels produce more, and lower in winter. Over the year, the total cost is similar to what a lease would average out to monthly. Either way, you skip the large upfront investment and avoid ongoing maintenance responsibilities — Palmetto handles that for you.
Compared to a cash purchase, a PPA lets you start saving on day one without needing to recoup a large initial cost or manage repairs yourself. Learn more about how Palmetto’s LightReach program makes solar accessible for Boulder homeowners — no ownership required.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Yes, solar makes strong sense in Boulder. With 300+ sunny days per year, 5.2 peak sun hours daily, and Colorado electricity rates rising over 15% since 2021, Boulder homeowners are well-positioned to benefit from solar. A typical system can save around $52,000 over 25 years.
Upfront cost doesn’t have to be a barrier. Palmetto’s LightReach solar lease lets Boulder homeowners go solar with no money down, starting at $75/month — so savings begin from day one.
Yes, Boulder has net metering. Boulder’s primary utility, Xcel Energy, offers 1:1 net metering, meaning the energy your solar panels send back to the grid is credited at the full retail rate. Excess credits roll over month to month as a dollar credit.
At your annual true-up, you can choose to cash out excess credits at the Average Incremental Cost Rate, or roll over credits indefinitely. Rolling over is generally the better option, since using credits at retail value later is worth far more than a small cash payout.
Yes, solar panels can increase your home value in Boulder. According to a Zillow study, homes with solar panels sell for 4.1% more on average than comparable homes without them. For Boulder’s competitive real estate market, that could represent a meaningful boost.
It’s worth noting that owned systems typically add more value than leased systems, since the buyer takes on the lease obligation. If maximizing resale value is a priority, a cash purchase may be the better path.
With Palmetto’s LightReach lease, Boulder homeowners can go solar for as low as $75/month — with no upfront cost. Palmetto owns and maintains the system, so you simply pay a fixed monthly payment and start saving immediately.
For those who prefer to own their system outright, a cash purchase typically runs between $14,941 and $24,885 depending on home size. Note that the federal 30% residential solar tax credit was eliminated by the Big Beautiful Bill. Use the calculator above for a personalized Boulder estimate.
For Boulder homeowners, solar can make strong financial sense — especially with a lease. With Palmetto’s LightReach program, there’s no upfront investment required. Your monthly lease payment is typically less than your current electricity bill, meaning most homeowners start saving on day one.
For those who purchase outright, Boulder’s 300+ sunny days and rising electricity rates support a solid long-term return — with average 25-year savings around $52,000. Either way, the financial case for solar in Boulder is clear.
Palmetto Solar is a top choice for Boulder homeowners. We’ve completed 1,534 installations across Colorado since 2020, bringing national expertise with a local focus. Our strong installer network ensures quality workmanship, and we offer some of the most flexible financing options in the industry.
Whether you prefer to own your system outright or go solar with no upfront cost through our LightReach lease (starting at $75/month), we make it straightforward for Boulder residents to start saving on their energy bills.
With Palmetto’s LightReach lease, Boulder homeowners can go solar for approximately $75/month — with no upfront cost. That estimate is based on a typical 6.40 kW system using Colorado’s production data. One simple monthly payment covers the system, installation, monitoring, maintenance, and a 90% Production Guarantee.
Because Palmetto owns the system, it qualifies for the commercial solar tax credit — and passes those savings to you through lower monthly payments. Since the lease payment is typically less than your current electricity bill, most Boulder homeowners start saving from day one.
