Black Hills Energy net metering is the arrangement most homeowners will encounter when they connect a rooftop or ground-mounted solar system to the grid, but it is not the only way a utility can compensate solar exports. For most homes with modest systems that are sized to cover their own usage, net metering is the simpler and more forgiving option. Homes that expect to produce far more power than they use, or that plan to add a large battery later, may find that a different export structure fits better. This comparison walks through the two main options and what each one means in practice.
Before you compare anything, confirm which tariff applies to your address and rate class. Utility programs in the Black Hills service territory can change as state commissions review them, so the details below describe the general structure and the questions to ask, not a guarantee of current terms.
Quick Comparison at a Glance
| Criterion | Net Metering (Retail Credit) | Net Billing (Avoided-Cost Credit) |
|---|---|---|
| How exported power is valued | Credited at or near the retail rate | Credited at a wholesale or avoided-cost rate, usually lower |
| Best system size match | Systems sized to offset your annual usage | Systems that will export a large share of output |
| Payback speed for typical homes | Generally faster | Generally slower unless paired with storage |
| Billing complexity | Monthly netting with possible annual true-up | Time-based or hourly export valuation, more variable |
| Battery compatibility | Works with batteries, though storage value is limited | Storage often improves the economics significantly |
| Ease of understanding your bill | Easier to follow month to month | Requires reviewing export rates and timing |
Credit Value for Exported Power: Who Wins
The biggest practical difference between the two structures is how a kilowatt-hour you send to the grid is valued. Under net metering, excess generation typically offsets your future consumption at close to the full retail rate. That means a kilowatt-hour you export on a sunny afternoon can cancel a kilowatt-hour you draw on a cloudy evening, dollar for dollar.
Under net billing, exported power is credited at an avoided-cost or wholesale-style rate. The utility values what it would have paid to generate or buy that power elsewhere, which is generally less than the retail price you pay for power drawn from the grid. The gap between those two numbers is the reason net billing tends to reduce the return on a system that exports heavily.
Winner: Net metering, for homeowners whose system output is roughly matched to their usage. The retail-rate credit makes each exported kilowatt-hour worth substantially more.
System Sizing and Export Behavior: Who Wins
Sizing matters more than most buyers expect. A system that is sized to cover your annual electricity use will export a fair amount during the day and draw from the grid at night, which means net metering delivers its full value. A system that is oversized relative to your load will push a large share of its output into the grid at lower credit rates.
To estimate your own balance, pull twelve months of usage from your Black Hills Energy statement and compare the annual total to the production estimate from your installer or from a solar modeling tool. If production is between roughly 80 and 110 percent of usage, net metering is usually the stronger choice. If production is well above usage, ask how exports will be valued before you sign.
Winner: Net metering for right-sized systems. Winner: Net billing is only worth considering for oversized arrays if the economics are modeled carefully, ideally with storage.
Payback Period: Who Wins
Payback depends on your installed cost, your local retail rate, the credit structure, available incentives, and how much of your production you use yourself. Under net metering, the retail-rate credit tends to shorten the payback window for a typical home system. Under net billing, the lower export rate stretches it, particularly if your daytime usage is low.
Self-consumption also matters. Every kilowatt-hour you use directly from your panels avoids buying power at the retail rate, regardless of which tariff you are on. Homes that are occupied during the day, or that run heavy loads like HVAC or water heating at midday, tend to see better outcomes under either structure.
Winner: Net metering for most typical homes. Homes with high daytime self-consumption close the gap considerably under net billing.
Billing Complexity and Bill Clarity: Who Wins
Net metering is easier to explain. Excess generation is accumulated as a credit that offsets future consumption, and many programs settle the balance on an annual true-up basis. Net billing usually involves more line items, time-of-use periods, or hourly export valuation, which can make monthly bills harder to predict.
If you are the type of homeowner who wants to glance at a bill and know what happened, net metering keeps the explanation short. If you enjoy tracking rate schedules, net billing is manageable, but plan to check your statements carefully during the first year.
Winner: Net metering, for clearer monthly bills and simpler annual reconciliation.
Battery Storage Compatibility: Who Wins
Batteries change the math. Under net metering, a battery can shift solar output to evening hours, which reduces grid purchases during peak-rate periods. Under net billing, a battery can store midday surplus and export it when the avoided-cost rate is higher, which can noticeably improve returns.
Manufacturers of home battery systems generally specify round-trip efficiency and usable capacity, so compare those figures alongside your utility’s export schedule. Storage adds equipment cost and complexity, so it makes the most sense when your rate structure rewards it.
Winner: Net billing when a battery is part of the plan, because storage can capture value that the lower export rate would otherwise leave on the table. Net metering still works well with a battery, but the incremental benefit is usually smaller.
Which Should You Choose?
- Choose net metering if your system is sized to offset most of your annual usage and you want the simplest, most forgiving credit structure.
- Choose net metering if you have limited daytime occupancy but expect to draw power in the evening, since monthly netting handles that pattern well.
- Choose net billing if your system will consistently produce far more than you use and you cannot reduce the oversizing.
- Choose net billing if you plan to install a battery and your utility’s export rates reward storing and exporting during peak hours.
- Choose net billing only after reviewing modeled savings with your installer, not on the basis of a generic brochure.
- Revisit the decision if your household load changes significantly, such as adding an electric vehicle or heat pump.

FAQ
Does Black Hills Energy net metering apply to every customer?
Eligibility depends on your rate class, system size limits, and the specific program in your state. Contact Black Hills Energy or review its published tariff sheets to confirm which provisions apply to your account before you commit to a system design.
What happens to excess solar power I produce in a month?
Under net metering, excess generation typically carries forward as a credit against future consumption. Many programs settle any remaining balance at the end of a twelve-month period. Your utility’s tariff will specify the exact treatment.
Is net billing always worse than net metering?
Not always. Net billing can perform well for homes with high daytime self-consumption or with battery storage that shifts exports to higher-value periods. The result depends on your load profile and local rate design.
Can I switch from net billing to net metering later?
Some programs allow transitions, but many lock in the tariff at the time of interconnection. Ask your utility about transition rules before you sign an interconnection agreement, since changing later may not be an option.
Should I hire a professional to evaluate my options?
Yes. Interconnection rules, tariff details, and electrical work involve safety and financial considerations. A licensed solar installer or electrician familiar with Black Hills Energy requirements can model your savings and confirm code compliance before you proceed.
Conclusion
For most homeowners with a right-sized rooftop system, Black Hills Energy net metering offers the stronger and simpler return, because exported power is credited at close to the retail rate and monthly bills stay easy to follow. Net billing becomes the better conversation when a system is oversized or paired with a battery that can capture higher-value export hours. Run the numbers on your own twelve-month usage, get a modeled comparison from a qualified installer, and confirm the current tariff terms with Black Hills Energy before you sign.
