Net metering rates by state determine how much your utility pays you for the solar electricity your home sends back to the grid. This guide walks you through what a net metering rate actually is, the state and utility factors that shape it, how to compare your options, and how to check the numbers on your own bill. By the end, you will know which questions to ask your utility and what to verify before you size a system.
What a Net Metering Rate Actually Means
A net metering rate is the value your utility assigns to each kilowatt-hour (kWh) your solar system exports to the grid. When your panels produce more electricity than your home uses at a given moment, the extra flows out to the grid and your meter runs backward. Over a billing period, the utility nets your exports against the power you pulled from the grid at night or on cloudy days. You pay for the net difference.

The rate is the key number. In many states, the export credit matches the retail rate you pay for electricity, so every kWh you send out offsets one you would otherwise buy. In other states, the export credit is lower than the retail rate, which reduces the value of each exported kWh. Some programs also pay a fixed avoided-cost rate instead of a retail-linked one. Reading the exact wording of your utility’s tariff is the only reliable way to know which applies to you.
Retail Rate Netting vs. Avoided-Cost Credits
Two structures show up most often:
- Full retail netting: Exports are credited at the same per-kWh rate you pay for consumption. This is the most generous structure for homeowners.
- Avoided-cost or export-rate credits: Exports are credited at a wholesale or utility-defined rate, often lower than retail. Many states that have revised their programs have moved in this direction.
Some utilities also split their credit into energy and delivery components, crediting only the energy portion. Check whether your tariff says “retail” or uses separate line items.
Why Net Metering Rates Vary by State
There is no single national net metering rate. Each state regulatory commission sets its own rules, and utilities operate under those rules within their service territories. As a result, two homes in neighboring states can receive very different credits for identical systems. Several factors drive the difference.
State Policy and Regulatory Direction
State public utility commissions decide whether net metering exists, how long it lasts, and how exports are valued. Some states have stable, long-running programs. Others have held periodic reviews that changed the credit structure for new customers. Policy can shift, so the rate you read about in an older article may no longer apply.
Utility-Specific Tariffs
Even within one state, rates can differ by utility. Investor-owned utilities, cooperatives and municipal providers often operate under separate tariffs. Your utility’s rate schedule, not the state average, is what governs your bill.
System Size and Customer Class
Many programs have size limits for residential systems, and some apply different terms to larger systems or to commercial customers. Time-of-use pricing can also change the value of exports, since a kWh sent out at a peak-price hour may be worth more than one sent out at midday.
Interconnection and Other Charges
Monthly fixed charges, minimum bills and interconnection fees affect your net outcome even when the export rate looks strong. A high fixed charge can cut into savings regardless of how well your panels perform.
Step-by-Step: How to Find and Compare Your Net Metering Rate
Follow these steps before you commit to a system size or sign an installation contract.
- Identify your utility. Your bill lists the company that delivers power to your address. This may differ from the company that sells you the electricity in deregulated markets.
- Locate the net metering tariff. Search your utility’s website for “net metering” or “distributed generation” along with your state name. Download the current rate schedule and any rider documents.
- Confirm the export credit structure. Look for whether exports are credited at retail or at an export or avoided-cost rate, and whether the credit is in kWh or dollars.
- Check the billing period and rollover rules. Find out whether unused credits roll forward month to month, whether they expire, and whether there is an annual true-up.
- Note any system size caps and eligibility rules. Confirm the maximum system size and whether your planned installation qualifies.
- Review fixed charges and minimums. Calculate what you pay each month regardless of usage.
- Ask for a written estimate. Request a projection from the utility or installer that shows your expected monthly net usage using your actual historical data.
Tools and Information You Will Need
- At least 12 months of your electricity bills, including kWh usage and total charges
- Your utility’s current net metering tariff and any rider documents
- Your roof orientation, shading notes and planned system size in kW
- A spreadsheet to compare scenarios side by side
Comparing Net Metering Structures in a Table
The table below summarizes the main structures you are likely to encounter. Use it as a starting point, then verify the specifics with your own utility.
| Structure | How exports are valued | What it means for you |
|---|---|---|
| Full retail netting | Exports credited at the consumption rate | Each exported kWh offsets a kWh you would buy; generally strongest for homeowners |
| Retail with time-of-use | Exports credited at the rate for the hour they occur | Value depends on when you produce; afternoon peak exports may earn more |
| Avoided-cost export credit | Exports credited at a utility-defined wholesale-linked rate | Usually lower value per kWh; self-consumption becomes more important |
| Net billing | Exports credited at a separate export rate, consumption billed at retail | Savings depend heavily on maximizing on-site use |
Estimating Your Own Savings Under Each Structure
To compare options, run the same production and usage numbers through each rate. Start with your annual consumption in kWh. Then estimate annual solar production using a local production estimate in kWh per kW installed. Split production into the share you consume directly and the share you export. Multiply exports by the export rate, and multiply avoided consumption by the retail rate. Subtract any added fixed charges. The result is your estimated annual benefit under that structure.
Run the calculation at two or three system sizes. Oversizing can look attractive under a generous credit but produce little value if the export rate is low. Undersizing leaves money on the table if exports are fully credited at retail. A licensed installer or energy consultant can help validate the numbers, especially where tax credits or financing are involved.
Common Mistakes to Avoid
- Relying on the state average. Your utility’s tariff governs your bill, not a statewide summary.
- Using an outdated rate. Programs change. Confirm the version of the tariff in effect on the day you apply.
- Ignoring fixed charges. A high monthly fee can erase part of your credit.
- Assuming all kWh credits are equal. Export credits and retail offsets can be worth very different amounts.
- Sizing for the sales pitch. Use your own consumption history rather than a generic estimate.
- Overlooking rollover and expiration rules. Unused credits can disappear at the end of a billing year.
Tips for a More Accurate Comparison
- Ask whether your rate is locked for the life of the system or can change later.
- Check whether a battery storage add-on changes how exports are credited.
- Review your utility’s annual reports or public filings for signals about future policy direction.
- If you are weighing several states, compare your current bills against potential solar outcomes using the same data.

FAQ
What is a net metering rate?
It is the per-kWh value your utility gives for electricity your solar system exports to the grid. This value determines how much each exported kWh offsets your bill.
Are net metering rates the same in every state?
No. Each state regulatory commission sets its own rules, and utilities apply their own tariffs within those rules. Rates and structures vary widely.
How do I find my utility’s net metering rate?
Search your utility’s website for its net metering or distributed generation tariff and download the current schedule. Your bill identifies your delivery utility.
Can net metering rates change after I install solar?
It depends on your state and utility. Some programs lock in terms for existing customers, while others apply new rules to later enrollees. Ask your utility to confirm in writing.
What is the difference between net metering and net billing?
Net metering typically credits exports at or near the retail rate. Net billing credits exports at a separate, usually lower, export rate while billing consumption at retail.
Do unused credits expire?
Some programs roll credits forward month to month and apply an annual true-up. Others have expiration rules. Check your tariff for the specific terms.
Should I consult a professional before choosing a system size?
Yes. Because tariff rules, tax treatment and financing terms can be complex, consider consulting a licensed solar installer, a utility representative or a qualified energy advisor before you sign a contract.
Conclusion
Net metering rates by state are shaped by state policy, utility tariffs, system size and fixed charges, so the number that matters is the one in your utility’s current schedule. Start by identifying your utility, confirming the export credit structure and checking rollover rules. Then model a few system sizes using your own usage history before you decide.
