Net Metering in Colorado: How It Works and What Homeowners Should Know

Colorado gets more than 300 sunny days a year — more annual sunshine than Miami or Honolulu. That's an obvious asset for solar, but sun alone doesn't make rooftop panels financially compelling. What turns that sunshine into real savings is net metering, and Colorado's version of it is one of the better programs in the country.

Here's a clear look at how net metering works in Colorado, which utilities offer it, what you need to know about the mechanics, and why the rate trajectory matters.

What Is Net Metering?

Net metering is a billing arrangement between you and your utility. When your solar panels produce more electricity than your home needs at a given moment, the excess flows back to the grid. Your meter effectively runs backward, and your utility credits your account for that energy.

What makes net metering valuable — and what varies from state to state — is the credit rate. Under Colorado's full retail-rate program, you earn credits for exported electricity at the same rate you'd pay to buy it. For Xcel Energy customers, that's approximately $0.14–$0.15/kWh on a flat-rate plan. Without net metering, utilities would pay only a wholesale or avoided-cost rate for your exported power — often just 3–5 cents per kWh — while still charging you full retail for every kWh you draw from the grid.

That gap is where the financial case for solar either stands or falls.

How Net Metering Works in Colorado

Colorado's net metering requirements are established by state statute and apply to investor-owned utilities and most electric cooperatives. Here's how the mechanics work in practice:

Monthly credit banking. When your system overproduces in a given month, you earn credits at the full retail rate. Those credits roll over month to month, letting you bank summer production to offset winter bills when shorter days mean reduced output.

Annual true-up. At the end of each calendar year, Xcel Energy customers can choose what to do with any remaining unused credits: roll them over indefinitely, or cash out at the Average Hourly Incremental Cost (AHIC) rate — the utility's wholesale rate, typically around 3–5 cents per kWh. Black Hills Energy customers receive a cash payout at year-end at a rate that, while below retail, is generally considered more generous than Xcel's wholesale rate.

System sizing cap. Colorado's investor-owned utilities allow residential systems sized up to 200% of your average annual electricity consumption — a notably generous cap compared to many states. That said, sizing well above your usage still doesn't make great financial sense, because credits cashed out at the end of the year are paid at wholesale rates, not retail.

Time-of-use nuances. Xcel Energy customers with smart meters are automatically enrolled in time-of-use (TOU) pricing, with on-peak rates around $0.22/kWh (afternoons and evenings on weekdays) and off-peak rates dropping to around $0.09/kWh. For solar customers, TOU is a double-edged sword: your panels produce most of their power during off-peak hours when rates are lower, while you're buying from the grid during the expensive evening peak. This is an important nuance that affects how you should think about system design — and whether a battery makes sense.

Which Utilities Offer Net Metering in Colorado?

Colorado law requires its two investor-owned utilities to offer net metering:

• Xcel Energy — serving the Denver metro area, Boulder, Fort Collins, Pueblo, and much of the Front Range; the largest utility in the state
• Black Hills Energy — serving Pueblo, Canon City, and parts of southern Colorado

Beyond the IOUs, most larger electric cooperatives also offer net metering or comparable billing programs, including CORE Electric Cooperative (serving the Castle Rock/Parker area), United Power, Holy Cross Energy, and others. Municipal utilities — like Colorado Springs Utilities and Fort Collins Utilities — run their own programs with their own rate structures.

One exception: smaller municipal utilities serving fewer than 5,000 customers are not required by state law to offer net metering. If you're served by a small co-op or municipal provider, it's worth confirming their policy directly before assuming you'll qualify.

Net Metering and the Solar*Rewards Program

Xcel Energy customers get something on top of net metering worth knowing about: the Solar*Rewards program, which pays a fixed rate per kWh of total solar production for 20 years — separate from and in addition to your net metering credits. The current standard rate is approximately $0.02/kWh on all power your system generates. Like net metering, you receive both simultaneously without any extra steps after enrollment.

Black Hills Energy offers a comparable production-based program paying $0.03/kWh for systems up to 20 kW.

These payments are modest in dollar terms but locked in for 20 years and additive on top of your net metering savings.

The Rate Trajectory Matters

One angle that often gets overlooked: net metering credits aren't just valuable today — they become more valuable as utility rates climb.

Xcel Energy has a pending rate increase before the Colorado Public Utilities Commission, with a decision expected in Q3 2026. Xcel originally filed for a 9.9% increase, but a settlement submitted in June 2026 between Xcel, corporate customers, and trade unions would reduce that to approximately 6% — raising the average residential bill by around $6/month. Consumer advocates are opposing the settlement and pushing for full hearings, so the final outcome remains uncertain. Either way, an increase is coming, and it follows years of steady rises — Colorado rates have climbed roughly 62% since 2014.

Every time rates go up, the value of the electricity your panels produce rises with it. A system you install today offsets power at whatever Xcel charges over its 25-year life, not just at today's rate. Net metering is what lets you capture that compounding benefit.

Net Metering and Battery Storage

With Xcel's TOU pricing, a battery system plays a particularly strategic role in Colorado. Because solar panels produce power primarily during off-peak hours — when rates are around $0.09/kWh — and most households draw from the grid during on-peak hours when rates hit $0.22/kWh, a battery that captures midday solar production and deploys it during the evening peak can meaningfully improve your economics compared to exporting that energy through net metering alone.

In other words: in Colorado, self-consumption through a battery is often worth more than a net metering export, specifically because of the TOU spread. That's a different calculus than flat-rate states, and worth factoring into your system design conversation.

A Note on System Sizing

Colorado's 200% sizing cap is generous, but that doesn't mean it's wise to build toward it. Credits left over at the annual true-up are paid at wholesale rates of 3–5 cents per kWh, while replacement grid power costs 14–15 cents per kWh on a flat rate — or up to 22 cents during peak hours on TOU. The math on deliberate oversizing never works out.

The right target for most Colorado homeowners is a system that offsets close to 100% of annual consumption, sized to maximize self-consumption and the retail-rate value of net metering credits throughout the year.

The Bottom Line

Colorado's net metering policy is genuinely strong — full retail-rate credits, flexible year-end rollover options, a generous 200% sizing cap, and broad coverage across IOUs and most cooperatives. The TOU dimension adds a layer of complexity that's worth understanding, but it also creates a clear opportunity for homeowners who pair solar with battery storage.

Net metering is the engine underneath the financial case for solar in Colorado. Understanding how your utility handles credits, how TOU pricing affects your calculations, and how exports are valued at year-end is the foundation for making a well-informed decision.
