Solar Billing Plan for Berkeley Homeowners
Also known as Net Billing Tariff or “NEM 3.0” — how solar exports and credits work for Berkeley customers.
Last updated: February 2026
What Is the Solar Billing Plan?
The Solar Billing Plan (also called Net Billing Tariff) replaced NEM 2.0 for all new solar interconnection applications submitted on or after April 15, 2023, per CPUC Decision 22-12-056. Under this plan, the value of solar energy you export to the grid is based on time-varying rates — not the full retail rate you pay for electricity.
Self-Consumption (Most Valuable)
Energy you generate and use immediately offsets your bill at the full retail rate ($0.35–$0.55/kWh depending on time of use). This is by far the most valuable use of your solar energy under the Solar Billing Plan.
Grid Exports (Lower Value)
Excess energy exported to the grid earns time-varying credits that are significantly lower than retail rates. This is the key difference from NEM 2.0, where exports were credited at (or near) retail.

Export Credit Values
Export credits under the Solar Billing Plan average approximately $0.04–$0.09/kWh during peak solar production hours. PG&E publishes hourly, daily, and monthly export credit values so customers can see exactly what their exports are worth.
When Are Export Credits Highest?
- • Midday (10 AM–2 PM): Lowest export value — this is when solar production across California peaks and the grid has the most surplus.
- • Late afternoon (3–6 PM): Higher export value — demand begins to rise while solar production starts to decrease.
- • Evening peak (4–9 PM): Highest grid value — but most solar systems produce little or no energy during these hours without battery storage.
The time-varying nature of export credits is why battery storage has become so important: it lets you store midday solar and use or export it during higher-value hours.

ACC Plus Export Adder
The ACC Plus Export Adder (also called the “Energy Export Bonus Credit”) is an additional credit on top of the base export value. It applies to residential PG&E customers who interconnect their solar system during the first five years of the tariff (2023–2027).
Key Details
- • Available for interconnections 2023–2027
- • Amount steps down each interconnection year
- • Locked in for 9 years from your PTO date
- • Code-required solar (new construction mandates) is excluded
Why It Matters
The ACC Plus adder meaningfully improves the economics of solar under the Solar Billing Plan. Since it steps down each year and is locked for 9 years, earlier interconnection means a higher, longer-lasting bonus.

E-ELEC: The Default Solar Rate Plan
Solar Billing Plan customers are automatically enrolled in PG&E's Electric Home (E-ELEC) rate plan. This is a time-of-use rate with a non-bypassable $15/month base services charge.
E-ELEC Time-of-Use Periods
Seasons: Winter (Oct–May) / Summer (Jun–Sep)
Other Rate Plan Options
While E-ELEC is the default, solar customers can also choose E-TOU-C (peak 4–9 PM daily), E-TOU-D (peak 5–8 PM weekdays), or EV2-A (favorable for EV owners). Comparing rate plans based on your usage patterns can optimize savings.

Why Batteries Matter Under the Solar Billing Plan
Under the Solar Billing Plan, the gap between self-consumption value ($0.35–$0.55/kWh) and export credit value ($0.04–$0.09/kWh) makes battery storage significantly more impactful than under NEM 2.0.
Without Battery
Typical self-consumption rate of ~70%. Excess midday solar is exported at low credit values. You buy grid power at full retail during expensive evening peak hours.
With Battery
Self-consumption rate increases to ~90%. Midday solar charges the battery, then powers your home during peak hours (4–9 PM) when rates are highest.
Battery Economics
- • Battery cost: $900–$1,200 per kWh of storage capacity
- • A typical 13.5 kWh battery: $12,150–$16,200
- • Note: The 30% federal tax credit expired Dec 31, 2025
- • Mid-life replacement typically needed after 10–15 years, which should be factored into long-term ROI calculations

Ava Community Energy Bonuses
Berkeley residents have a unique advantage: Ava Community Energy provides additional export credits on top of the standard Solar Billing Plan credits. These bonuses are available for 5 years (2024–2029) and are separate from the ACC Plus adder.
Non-CARE/FERA Customers
+$0.025/kWh bonus for solar exports during peak hours (3–8 PM). This stacks on top of PG&E export credits and the ACC Plus adder.
CARE/FERA Customers
+$0.01/kWh bonus on all solar exports (not limited to peak hours). Available for qualifying low-income households.
Berkeley-specific advantage: The combination of Ava export bonuses + ACC Plus adder + standard Solar Billing Plan export credits means Berkeley solar customers earn more per exported kWh than PG&E-only customers in neighboring cities.
True-Up and Cash-Out
Under the Solar Billing Plan, you receive monthly statements showing your energy usage, generation, exports, and credits. However, the financial settlement happens on an annual cycle.
Monthly Statements
Each month, your bill shows charges and credits. Any net credits roll over to the next month. You won't receive a payout until the annual true-up.
Annual True-Up
Your annual true-up typically occurs in April. At true-up, PG&E settles the balance for the full 12-month period. If you have surplus kWh, they're paid out at the Net Surplus Compensation (NSC) rate.
Cash-Out Rules
- • If the cash-out value is under $100, the surplus stays as a bill credit
- • If the cash-out value is $100 or more, PG&E issues a check (typically in June–July following the April true-up)
- • Most solar-only systems are designed to offset most — not all — of your usage, so large payouts are uncommon
