If you are a solar homeowner (or considering solar) in the Denver metro area or along Colorado's Front Range, you are almost certainly an Xcel Energy customer. Understanding Xcel's net metering policies is essential to maximizing your solar investment. Net metering determines how you are credited for the excess electricity your solar panels send to the grid — and it directly affects your savings.
This guide covers everything you need to know about Xcel Energy's net metering program in Colorado, including current rates, billing mechanics, time-of-use options, and practical strategies to get the most value from your solar system.
What Is Net Metering?
Net metering is an arrangement between you and your utility where you receive credit for excess electricity your solar system sends to the grid. During sunny midday hours, your panels typically produce more electricity than your home consumes. That excess flows to the grid, spinning your meter backward (or crediting your account digitally).
Later — in the evening, at night, or on cloudy days — when your home draws more electricity than your panels produce, you pull from the grid. Net metering lets you offset those grid draws with your earlier credits.
The result is that you effectively use the grid as a battery: storing excess solar production during the day and drawing it back when you need it, without the cost of an actual battery storage system.
For a broader explanation of net metering, see our net metering explained guide.
Xcel Energy Net Metering Basics
Eligibility
All Xcel Energy residential customers in Colorado are eligible for net metering with a qualifying solar system. Key eligibility requirements include:
- System size limit: Up to 120 percent of your previous 12 months of electricity consumption (this prevents oversizing systems purely for export)
- Interconnection approval: Your system must be approved through Xcel's interconnection process
- Licensed installation: System must be installed by a licensed electrical contractor
- Metering: Xcel installs a bidirectional meter that tracks both imports and exports
How Credits Work
Xcel Energy credits your solar exports at the full retail rate on a kilowatt-hour basis. Here is the billing cycle:
- Real-time metering: Your bidirectional meter tracks electricity flowing in both directions
- Monthly netting: At the end of each billing period, Xcel calculates the net difference between what you consumed from the grid and what you exported
- Net consumer month: If you consumed more than you exported, you pay for the net consumption at your applicable retail rate
- Net producer month: If you exported more than you consumed, the excess credits roll forward to the next month
- Annual true-up: Once per year (in your April billing cycle), any remaining excess credits are cashed out at Xcel's average hourly incremental cost (AHIC), which is significantly lower than retail rates — typically $0.03 to $0.05 per kWh
The Monthly Service Charge
Regardless of how much solar you produce, Xcel charges a fixed monthly service charge of approximately $10 to $12. This covers your connection to the grid and is not offset by solar credits. Your electric bill will never be $0.
Rate Structures
Xcel Energy offers residential customers several rate structures that affect how solar credits are valued:
Standard Rate (R): A flat rate per kWh regardless of when you use electricity. This is the simplest structure and is the default for most customers. The current residential rate is approximately $0.14 to $0.17 per kWh (varies by usage tier and season).
Time-of-Use Rate (RE-TOU): Different rates depending on when you use electricity:
- Off-peak: Approximately $0.08-$0.10/kWh (nights, early mornings, weekends)
- Mid-peak: Approximately $0.12-$0.15/kWh (daytime hours excluding peak)
- On-peak: Approximately $0.18-$0.25/kWh (typically 3 PM to 7 PM on weekdays)
Why TOU matters for solar: Your solar panels produce the most electricity during midday hours — which under TOU pricing are mid-peak, not on-peak. The highest rates apply in late afternoon and early evening (3-7 PM), when your solar production is declining. This means TOU rates can actually reduce the value of solar exports compared to the flat rate, unless you have a battery to shift solar energy to peak hours.
Maximizing Your Savings with Xcel
Strategy 1: Right-Size Your System
Design your system to offset 90 to 100 percent of your annual consumption, not more. Excess credits beyond your annual usage are cashed out at the low AHIC rate ($0.03-$0.05/kWh) during the annual true-up, representing poor value for your exported electricity.
A properly sized system produces approximately what you consume on an annual basis, maximizing the value of every kilowatt-hour at full retail rate. ProGreen Solar uses your actual Xcel Energy usage data to size your system optimally.
Strategy 2: Shift Consumption to Solar Hours
If you can shift energy-intensive activities to midday when your panels are producing:
- Run your dishwasher during the afternoon instead of evening
- Do laundry on sunny afternoons
- Charge your EV during the day if you have a home charger and your car is parked
- Pre-cool your home in the afternoon before evening peak hours
This self-consumption is worth more than exporting to the grid because you avoid the round-trip through net metering and any future policy changes.
Strategy 3: Consider Battery Storage Strategically
If you are on Xcel's TOU rate, a battery system can shift solar energy from midday production to evening peak consumption. You charge the battery during midday solar hours and discharge during the 3-7 PM peak window, offsetting electricity at the highest rate.
The financial benefit depends on the TOU rate differential. Currently, the spread between off-peak and on-peak is about $0.10-$0.15/kWh. For a 13.5 kWh battery cycling daily, that represents $1.35-$2.00 per day or $490-$730 per year in rate arbitrage value. Combined with backup power value, this can justify battery investment for some homeowners.

Strategy 4: Use the Standard Rate (Not TOU) in Most Cases
Unless you have a battery or can significantly shift your consumption to off-peak hours, the standard flat rate often provides better solar economics than TOU rates. Under the flat rate, every kWh of solar production offsets consumption at the same rate, regardless of time of day.
On TOU, your midday solar exports are credited at a lower rate than the evening electricity you need to buy. Without a battery to bridge this timing gap, TOU can reduce your net savings compared to the flat rate.
Strategy 5: Monitor Your System
Active monitoring helps you identify and address issues quickly. A panel failure or inverter issue that goes unnoticed for months costs you real money. Both Enphase Enlighten and SolarEdge monitoring provide real-time production data and alerts.
Xcel's Interconnection Process
Getting your solar system connected to Xcel's grid involves a formal interconnection process:
Step 1: Application
Your installer submits an interconnection application to Xcel Energy on your behalf. This includes system specifications, electrical diagrams, and site details.
Step 2: Engineering Review
Xcel reviews the application to ensure the system meets their technical requirements and will not cause grid issues. For standard residential systems under 25 kW, this is typically straightforward.
Step 3: Approval and Meter Installation
Once approved, Xcel installs a bidirectional meter (or upgrades your existing meter). This typically happens within two to four weeks of application submission.
Step 4: Permission to Operate (PTO)
After your system passes local electrical inspection and Xcel installs the meter, you receive Permission to Operate. Only after receiving PTO should you turn on your system and begin generating.
Important: Do not operate your solar system before receiving PTO from Xcel Energy. Generating without approval can result in penalties and delays.
Timeline
The full interconnection process typically takes three to six weeks from application to PTO. ProGreen Solar handles the entire process on your behalf.
Understanding Your Xcel Bill with Solar
Your monthly Xcel bill with solar will include:
- Monthly service charge: $10-$12 (fixed, regardless of solar)
- Energy charges: Based on your net consumption (grid imports minus solar exports)
- Renewable Energy Standard Adjustment: A small charge supporting Colorado's renewable energy programs
- Franchise fees and taxes: Various local fees
- Net metering credits: Shown as credits offsetting energy charges
In months when your solar production exceeds your consumption (typically April through September), your bill will be close to the minimum service charge. In winter months with lower production and higher heating-related consumption, your bill will be higher.
Over a full year, a properly sized system reduces your total Xcel electricity costs by 70 to 95 percent, depending on system size relative to consumption.
Future of Xcel Net Metering
Net metering policies are subject to change through regulatory proceedings at the Colorado Public Utilities Commission (PUC). Here is what to know:
Grandfathering
Historically, customers who install solar under current net metering rules are "grandfathered" — they continue to receive those terms for a set period (typically 20 years) even if policies change for new customers.
Potential Changes
The solar industry is watching several potential policy developments:
- Shift from retail-rate credits to "value of solar" or avoided-cost credits (would reduce export value)
- Expanding TOU rate adoption with wider peak/off-peak differentials
- Demand charges for residential customers (charges based on peak demand rather than just consumption)
- Grid access fees for solar customers
None of these changes are imminent, but they reinforce two principles: install solar sooner rather than later to lock in current favorable terms, and consider battery storage to reduce your dependence on net metering credits.
Colorado's Solar-Friendly Policies
Colorado's strong renewable energy standards and legislative support for distributed solar make dramatic net metering reductions less likely than in some other states. The state has demonstrated consistent political support for residential solar, and the PUC has historically maintained favorable policies.
