Step 1
Find the NEM schedule on your bill
Open your most recent electric bill and look for the rate schedule. It is usually printed near the top of page 2 or in a “Service Details” / “Rate Schedule” box.
Look for one of these labels: NEM2 (NEM 2.0 — the good one), NEM (legacy NEM 1.0), or NBT (Net Billing Tariff — that is NEM 3.0).
Step 2
NEM2 vs NBT — what each means
| Label on bill | What it is | Export value |
|---|---|---|
| NEM2 | NEM 2.0 (grandfathered) | ~$0.30–$0.39/kWh |
| NBT | NEM 3.0 (current default) | ~$0.05–$0.08/kWh |
Step 3
Check the true-up period
NEM 2.0 accounts settle on an annual true-up (once a year, the utility reconciles your net exports/imports for the prior 12 months). NEM 3.0 (NBT) accounts settle monthly. If your bill references an annual true-up cycle, that is a strong signal you are on NEM 2.0.
Step 4
Confirm the PTO date
The PTO (Permission to Operate) date is when the utility turned the system on — it starts the 20-year grandfathering clock. NEM 2.0 also required an interconnection application on or before April 14, 2023, with PTO within three years. The PTO date is usually in your original interconnection paperwork and may appear in your utility portal under the solar/net-metering section.
Plug the PTO date into our NEM 2.0 grandfathering calculator to see exactly when grandfathering expires.
By utility
Where to look for SCE, PG&E, and SDG&E
- SCE (Southern California Edison): sign in at sce.com, open your account, and look under Service Details → Rate Schedule. NEM 2.0 shows as “NEM2”.
- PG&E: sign in at pge.com, go to Energy Usage → Solar Generation, and check the NEM agreement type.
- SDG&E: sign in at sdge.com and look under My Energy → Net Energy Metering.
If you cannot find the PTO date or NEM schedule, request a complimentary assessment and a licensed contractor will pull it for you.
