— What is NEM 3.0 —
Your utility company changed the rules.
NEM 3.0 — officially the Net Billing Tariff (NBT) — is California’s current solar billing policy for PG&E, SCE, and SDG&E customers. It took effect April 15, 2023. The result? When your solar panels produce more electricity than your home uses, PG&E now pays you a fraction of what they charge you for power.
In plain language: they buy cheap, they sell expensive. And they changed the rules without asking you. That’s exactly why we exist.
Important deadline passed: April 15, 2026 was the final date to achieve Permission to Operate under NEM 2.0 grandfathering. All new systems now fall under NEM 3.0. Contact us to understand your current situation and your best path forward.
How we got here
- 1996
- 2017
- Apr 2023
- Mar 2026
NEM 1.0 — California launched the country’s first net metering program. Solar owners earned full retail credit for every kWh they sent to the grid. Participation capped at 5% of utility capacity.
— NEM 2.0 VS. NEM 3.0 —
What actually changed — and what it costs you.
One number tells the whole story: the value of electricity you export to the grid dropped by three-quarters. Everything else flows from that single shift.
Full retail credit for your exports
When your panels produced more than you used, PG&E credited you at close to the retail rate. A solar-only system could offset most or all of your bill. Payback period: 6–7 years.
Avoided cost: a fraction of retail
The key insight: Under NEM 3.0, electricity you store and use yourself is worth 4–6x more than electricity you export to the grid. A battery is the weapon. Store your solar — don’t give it away cheap.
Other changes under NEM 3.0
- Mandatory TOU enrollment — All NEM 3.0 customers must be on a Time-of-Use rate plan. Electricity costs more during evening peak hours (4–9 PM) — exactly when your panels have stopped producing.
- ACC Plus adder — A small additional export credit that decreases 20% per year for PG&E and SCE customers, reaching zero for new applicants after April 2028.
- Annual true-up — Unused export credits no longer pay out as cash. They’re applied to your bill over 12 months, then expire. Oversizing solar is now inefficient.
- New Base Services Charge (March 2026) — PG&E added a ~$24/month fixed charge for most residential customers. Solar + storage helps offset this unavoidable monthly fee.
— Who's affected —
Are you in PG&E territory?
NEM 3.0 applies to PG&E customers across Northern and Central California. If you live in any of Continuum’s service counties, this policy applies to you.
New solar customers
Any system installed after April 14, 2023 in PG&E territory falls under NEM 3.0. Battery storage is essential for all new installs.
NEM 2.0 homeowners
Locked in before April 2023? Your NEM 2.0 rates are protected for 20 years. Adding storage does NOT affect your grandfathered status.
Wildfire zone residents
Sierra Foothills, Napa hills, Shasta, Butte County — solar + storage is both a financial decision and a safety one. PSPS protection is essential.
EV homeowners
Driving an EV in PG&E territory? Solar + storage lets you charge on your own midday solar instead of paying peak grid rates. Massive savings.
— The solution —
Battery storage: the weapon NEM 3.0 created.
NEM 3.0 didn’t kill solar in Northern California. It changed the strategy. The homeowners who understand this are winning. Those who don’t are losing money every single day.
The logic is straightforward: store your solar, don’t sell it cheap.
Solar-only vs. solar + storage
Typical PG&E customer on a 7.2 kW system
payback period
— Exports excess solar at ~$0.06/kWh
— Buys peak power at ~$0.50/kWh
— No protection during PSPS outages
— Limited to daytime bill savings only
shorter payback — despite higher upfront cost
How it works in your home
- 6 AM–8 AM: Home runs on stored battery power. You avoid buying expensive morning grid power.
- 8 AM–4 PM: Panels produce at full capacity. Home uses solar directly. Excess charges your battery. You keep your power.
- 4 PM–9 PM: Peak hours. Grid hits $0.40–$0.55/kWh. Your battery discharges. You buy almost nothing from PG&E.
- 9 PM–Midnight: Off-peak rates return. Battery tops off from cheap overnight grid power if needed.
A median customer saves $720/year with solar only — but $1,649/year with solar + storage. That’s a 129% improvement. The battery pays for itself by eliminating your most expensive electricity purchases every single evening.
How it works in your home
- Tesla Powerwall 3 — 13.5 kWh, 11.5 kW output. Fully integrated solar + storage. Ideal for whole-home backup and TOU optimization.
- Enphase IQ Battery 10T — Modular and highly reliable. Pairs perfectly with Enphase microinverter systems. Outstanding monitoring.
- 4Franklin Whole-Home Battery (aPower 2) — High-output for large homes or multi-battery setups. Strong performance during extended outages.
— TOU Strategy —
Know when electricity is cheap. Know when it's expensive.
Under NEM 3.0, all PG&E solar customers must be on a Time-of-Use rate plan. The price you pay for electricity varies throughout the day. Understanding this is the key to maximizing your savings.

Continuum tip: Homeowners in the Sierra Foothills, Napa hills, Shasta, and Butte County communities are particularly likely to qualify for elevated SGIP Equity Resiliency rebates due to their fire risk designation. If your address has experienced a PSPS event, ask us specifically about this tier.
— PSPS & Wildfire Protection —
Your solar does nothing during a power shutoff. Unless you have a battery.
What happens to your solar during a PG&E PSPS?
Here’s what most homeowners don’t know: a standard grid-tied solar system is required by code to shut off during any grid outage — including intentional PSPS events — to protect utility workers. Even on a bright sunny day, your panels go dark the moment PG&E cuts power to your street.
Without battery storage: you sit in the dark like everyone else. With a properly configured Continuum system: your home automatically islands from the grid and runs on stored solar power — completely independent of whatever PG&E is doing. Keep the lights on. Keep the fridge running. Keep your family safe.
Continuum installs battery systems configured for full islanding capability — automatic transfer switching that disconnects from the grid during an outage and runs your home on battery + solar self-sufficiency within milliseconds.
In 2025, residential battery systems across California provided millions of hours of backup power during outage events. For Northern California homeowners who’ve lived through PSPS events, this resilience value is often the primary reason they choose solar + storage — and it’s a reason that has nothing to do with your electricity bill.
— Already have solar? —
Your next move depends on when you installed.
You're in a powerful position.
You're leaving money on the table every day.
If you went solar after April 2023 without a battery, adding storage now is your most impactful financial move. Every day you wait, you’re selling excess midday solar at ~$0.06/kWh that you could be storing and using at ~$0.45/kWh value during evening peak hours.
The payback on adding storage to an existing NEM 3.0 solar system is typically strong — especially with available SGIP rebates. Contact us for an analysis specific to your system and bills.
Going solar in 2026 means going solar + storage.
Full stop. Continuum designs every NEM 3.0 system as an integrated solar and battery system from the ground up — sized precisely for your home’s energy usage and TOU profile, not oversized for exports that aren’t worth much anyway. We’ll show you exactly what your system will cost, what you’ll save, and when you’ll break even.

Frequently asked questions
What is NEM 3.0 in California?
NEM 3.0, officially the Net Billing Tariff (NBT), is California’s current policy governing how homeowners with solar panels are compensated for energy they export to the grid. It applies to PG&E, SCE, and SDG&E customers. Under NEM 3.0, export credits dropped ~75% compared to NEM 2.0 — from roughly $0.30/kWh to $0.05–0.08/kWh. The policy took effect April 15, 2023 and was upheld by California courts in March 2026.
Does NEM 3.0 apply to SMUD customers in Sacramento?
No. NEM 3.0 applies only to PG&E, SCE, and SDG&E customers. Sacramento Municipal Utility District (SMUD) customers operate under a separate, currently more favorable net metering program. Continuum installs in both territories — call us and we’ll tell you exactly what rules apply to your address.
Can I add a battery to my existing NEM 2.0 solar system?
Yes — and it will not affect your NEM 2.0 grandfathered status. This is one of the most important things to understand right now. You keep your favorable export rates and gain all the benefits of battery storage: peak-hour bill avoidance, PSPS backup protection, and SGIP rebate eligibility. Call us for a free retrofit assessment — your existing inverter may already be compatible.
Is solar still worth it in Northern California under NEM 3.0?
Yes — absolutely. But the strategy is different now. Solar-only systems still make economic sense (8–10 year payback) given PG&E’s high rates. Solar + storage systems do better — shorter payback, dramatically higher savings — because they eliminate your most expensive electricity purchases. Add the wildfire/PSPS resilience factor and solar + storage is one of the most defensible investments a Northern California homeowner can make.
What is the SGIP rebate and how much can I get?
SGIP is California’s battery storage rebate program. Amounts depend on your income and location. Standard rebates cover 20–40% of battery costs. Equity-eligible customers (lower income households) may qualify for rebates covering up to 100% of costs. Homeowners in High Fire Threat Districts or those who have experienced PSPS events may qualify for enhanced Equity Resiliency rebates. Continuum handles all SGIP applications on your behalf.
Will my solar panels work during a PG&E PSPS outage?
Not without a battery. Standard grid-tied solar systems are required by code to shut off during any grid outage — including PSPS events — to protect utility workers. Your panels go dark even on a sunny day. Battery storage changes this completely. A properly configured Continuum system will island from the grid during an outage and run your home on stored solar power for hours or days, completely independent of PG&E.
How much does a solar + battery system cost in Northern California?
Solar panels alone run approximately $2.60–$3.20/watt installed (a 7 kW system: $18,000–$22,000). Battery storage adds $10,000–$18,000 for a single Powerwall 3 or equivalent. SGIP rebates can reduce battery costs significantly. Continuum provides free, detailed quotes showing your net cost after all available incentives — call or book online for yours.
