How Does PGE Net Metering Work? A Homeowner’s Step-by-Step Guide

By Claire Whitaker

Updated November 2026

If you are wondering how does PGE net metering work, the short answer is this: when your rooftop solar system sends more electricity to the grid than your home uses, your meter runs backward and that surplus is credited against the energy you draw later. In this guide, you will learn how PGE tracks those exports and imports, how the credits appear on your bill, what paperwork and equipment you need, and where homeowners most often run into trouble.

Note: Net metering rules, rate structures and program names change over time and can depend on your PGE service territory and the date your system was approved. Confirm current terms with PG&E or Portland General Electric directly, and consult a licensed electrician or solar installer before making changes to your service.

What Net Metering Means for a PGE Customer

Net metering is a billing arrangement, not a separate piece of hardware. Your solar array produces direct current, an inverter converts it to alternating current, and that power either feeds your home’s loads first or flows out to the utility grid. Your utility meter measures both directions of flow.

Over a billing period, the utility compares what you pulled from the grid with what you pushed back. If you exported more than you imported, you carry a credit forward. If you imported more, you pay for the difference at the applicable rate. The credit is typically measured in kilowatt-hours and applied to future bills, though the exact method depends on your rate schedule and any transition rules that applied when your system was interconnected.

Two terms show up on most PGE-area agreements and bills, and it helps to know them early:

• Exports: kilowatt-hours your system sends to the grid.
• Imports: kilowatt-hours you draw from the grid, usually at night or on cloudy days.

Because solar output peaks around midday and household demand often peaks in the evening, your exports and imports rarely match hour by hour. Net metering smooths that mismatch over the billing cycle.

Step-by-Step: How PGE Turns Solar Exports Into Bill Credits

Step 1: Your inverter sends power to the home first

Solar power goes to whatever is running in your home at that moment: the refrigerator, lights, HVAC, an electric water heater. Only the surplus leaves the house and flows to the grid. This matters because every kilowatt-hour you use directly from your panels is one you never have to buy back, and it is also one you do not export for a credit.

Step 2: Your bidirectional meter records both directions

Your utility meter, which the utility typically installs or upgrades when your interconnection is approved, records energy in both directions. It logs imports and exports separately so billing staff can see both totals. If your meter has not been changed since before your system went live, ask PGE whether a bidirectional meter is in place.

Step 3: The billing cycle totals your net usage

At the end of each cycle, the utility subtracts exports from imports. Several outcomes are possible:

Step 4: Check how credits are valued

Credits are not always worth the same as the rate you pay for grid power. Some tariffs value exports at a different rate than the retail rate for imports, and time-of-use schedules can make a kilowatt-hour exported at 6 p.m. worth more or less than one exported at noon. Read the rate schedule attached to your interconnection agreement so you understand which version applies to you.

Step 5: Confirm the credit on your statement

Your monthly statement should show exported energy, imported energy, net energy, and any carried-forward credit. If the numbers do not reconcile with your inverter or monitoring app over the same period, request meter data from PGE and compare readings. Small timing differences are normal; large gaps are worth raising.

What You Need Before Net Metering Applies

Net metering is not automatic for every rooftop array. Your system generally must be approved and interconnected under a utility agreement. A typical checklist looks like this:

1. Submit an interconnection application to PGE with your system size, inverter specifications and site plan.
2. Obtain required permits from your city or county building department.
3. Use equipment listed for grid interconnection, such as UL 1741 certified inverters, and have the installation inspected.
4. Receive permission to operate (PTO) from the utility before energizing the system.
5. Confirm that a bidirectional meter is installed and that your account is enrolled in the correct net metering rate.

Your interconnection agreement should state which rate schedule you are on and how credits roll forward. Keep a copy with your solar paperwork.

Tools and Monitoring That Help You Track Credits

You do not need special tools to read your bill, but a few items make it easier to verify what PGE records:

• A monitoring display or app from your inverter manufacturer, showing production and self-consumption.
• Your PGE online account, where you can download interval or daily usage data.
• A simple spreadsheet to log monthly exports, imports and credit balances for at least one year.

Common Mistakes to Avoid

• Assuming every kilowatt-hour is worth the retail rate. Check the export valuation in your tariff.
• Ignoring the billing cycle. A cloudy month can create imports even in a productive year, so look at trends over 12 months.
• Running the system before permission to operate. This can create safety hazards and billing disputes.
• Adding batteries or changing system size without notifying PGE. Modifications may require a new interconnection review and can change your rate eligibility.
• Not comparing meter readings with your inverter data. Discrepancies are easier to fix when you catch them early.

Tips for Getting the Most From PGE Net Metering

• Shift flexible loads such as laundry, dishwashing and EV charging toward midday when your panels are producing.
• If your rate is time-of-use, compare the value of exports during peak hours against off-peak hours before choosing a rate plan.
• Right-size your system to your annual usage so you are not building a large credit balance you may struggle to use.
• Review your statement each month for the first year and note any unexpected charges.
• If you plan to add a battery, ask about the rules for battery-charged exports before you buy.

Recommended gear

Monitoring your own production makes it easier to check PGE’s numbers against what your system actually generates. These are types of equipment that homeowners often use for this purpose:

• Solar production monitor with a current clamp: shows real-time consumption and export on a display in your home, so you can see when you are sending power to the grid. View on Amazon
• Clamp-on power meter: lets you check circuit loads with a handheld tool before and after changes to your schedule. View on Amazon
• Smart plug energy monitor: useful for measuring the kilowatt-hours used by a single appliance, such as a water heater or EV charger on a dedicated outlet. View on Amazon

FAQ

Does PGE pay cash for excess solar power?

Under standard net metering, excess exports are typically applied as bill credits rather than paid out in cash. Some situations, such as a large balance at the end of a program year, may be settled differently. Check your interconnection agreement for the exact terms.

Why is my net metering credit smaller than I expected?

Credits can be lower if your exports are valued at a different rate than your imports, if a time-of-use schedule applies, or if your system produced less than projected due to shading, weather or equipment issues. Compare your monthly production data with your statement.

Do I need a battery to use net metering?

No. Net metering works with a grid-tied system alone. A battery can change how much you export and when, and it may affect your rate eligibility, so confirm the rules with PGE before adding one.

How long does it take for PGE to approve a solar system for net metering?

Timelines vary with application volume, system size and whether upgrades to the local grid are required. Expect a multi-step process that includes review, inspection and permission to operate. Ask PGE for the current estimate when you apply.

What happens to credits if I move or sell my home?

Credits generally stay with the account, but policies on transfer and on the final settlement of unused credits can differ. Contact PGE before closing to understand how your balance will be handled.

Can I net meter if my system is on a rental property?

Eligibility depends on account holder status and the approved interconnection application. Landlords and tenants should confirm who is listed as the customer of record before installation.

Is net metering the same as net energy metering?

The terms are closely related and often used interchangeably. Some utilities use net energy metering (NEM) to describe versions of the program with specific export valuation rules. Confirm the program name on your agreement.

Should I hire a professional to check my PGE billing?

If your statements do not match your monitoring data, or if you are considering system changes, a licensed solar installer or electrician can help you review the setup. For billing disputes, start with PGE customer service and request written explanations.

Conclusion

PGE net metering works by netting your solar exports against the power you draw from the grid over each billing period, then applying any surplus as a credit to future bills. Knowing how your rate values exports, how your meter records both directions, and what your interconnection agreement says will help you predict your bill. Review your statements against your production data for the first year, and contact PGE or a licensed professional whenever the numbers do not match.
