SDG&E Solar True-Up Statement Audit: Surviving 68¢–81¢/kWh San Diego Electric Rates
With San Diego Gas & Electric (SDG&E) summer peak rates hitting $0.68 to $0.81 per kWh, even a small 2,500 kWh annual solar deficit triggers a brutal $1,800+ True-Up bill. Worse, San Diego Community Power (SDCP) and Clean Energy Alliance (CEA) split your True-Up across two different line items. Here is how to audit and crush your SDG&E True-Up bill.
Key Forensic Statement Takeaways
- ✓The EV-TOU-5 Super-Off-Peak Secret: If you own an EV or home battery in SDG&E territory, switching to **EV-TOU-5** (with a $16/month basic fee) drops your 12:00 AM–6:00 AM Super-Off-Peak rate down to ~$0.12–$0.15/kWh—while your NEM 2.0 daytime solar exports earn $0.42–$0.68/kWh!
- ✓What that 4x Rate Spread Means on NEM 2.0: On EV-TOU-5 under NEM 2.0, exporting 1 kWh of solar at 4:30 PM ($0.68 credit) buys you **5.2 kWh** of overnight EV charging between midnight and 6:00 AM ($0.13/kWh)!
- ✓SDCP / CEA Community Choice Aggregation Split: SDG&E bills Electric Delivery (annual True-Up), while San Diego Community Power (SDCP) bills Electric Generation. Check Page 5+ of your bill to verify both balances!
- ✓Fastest Battery ROI in America: Because SDG&E charges ~72¢/kWh during 4–9 PM summer peaks, a 13.5kWh LFP battery shifting 11 kWh/day saves ~$2,600/year—paying for itself in just 3.2 years!
Line-by-Line Utility Statement Decoder & Elimination Strategy
| Statement Line Item | What It Actually Means | Typical Cost / Rate | How to Slash or Zero It |
|---|---|---|---|
| SDG&E Electric Delivery NEM Summary | Tracks transmission, distribution, wildfire, and PPP charges (~55% of your total per-kWh rate!) | $0.36 – $0.45 / kWh Delivery Alone! | Only self-consumed solar or battery discharge avoids SDG&E delivery charges + NBCs |
| SDCP / CEA Electric Generation NEM Balance | Power generation charges managed by San Diego Community Power or Clean Energy Alliance | $0.16 – $0.34 / kWh Generation | Export solar during 4:00 PM–6:00 PM West-facing sun or discharge battery |
| EV-TOU-5 $16 Monthly Base Services Fee | Fixed monthly subscription fee that unlocks ~13¢/kWh overnight Super-Off-Peak power | $192/yr Fixed | Saves $1,400+/yr if you charge an EV or run pool/heat-pump loads between 12 AM and 6 AM! |
4-Step Action Plan to Eliminate Next Year's True-Up Bill
Charging an EV or running air conditioning on standard TOU-DR1 where even Off-Peak power above 130% Baseline costs $0.48+/kWh!
If you have an EV (or eligible energy storage), enroll in **EV-TOU-5** and set your EV to charge strictly from 12:05 AM to 5:55 AM (10 AM–2 PM on weekends).
Add a 13.5kWh–15kWh LFP battery to cover 100% of household loads from 4:00 PM to 9:00 PM.
Keep your existing NEM 2.0 array intact; add any extra solar panels as a separate Zero-Export + Battery system.
Optimization Wins
- +SDG&E EV-TOU-5 has the best Super-Off-Peak vs On-Peak ratio in California (13¢ vs 70¢+!)
- +Sub-3.5 year payback on home battery storage additions
- +April & October California Climate Credits (~$156+/yr in SDG&E) directly reduce delivery balances
Tariff Traps to Avoid
- −Highest penalty in the nation if your solar inverter breaks and you don't notice for 3 summer months ($500+/month lost!)
Frequently Asked Questions
Why is SDG&E's EV-TOU-5 rate schedule such a massive hack for NEM 2.0 solar owners?
On standard SDG&E rates (TOU-DR1), even night-time power costs 42¢–51¢/kWh once you pass 130% of baseline. On EV-TOU-5, you pay a flat $16/month fee and get unlimited 12:00 AM–6:00 AM Super-Off-Peak electricity for ~13¢/kWh—while all the solar power your panels export during the afternoon and 4–6 PM peak earns 40¢ to 70¢/kWh in credits!
Should I choose Monthly NEM Billing or Annual True-Up Billing with SDG&E?
Always choose Annual True-Up Billing! If you choose Monthly Billing, you cannot carry your huge April–July sunny surplus credits forward into November–January to offset short winter days.
