PG&E Solar True-Up Bill Shock Explained: Line-by-Line Audit of a $2,400 Annual Bill
Every month for 11 months, your PG&E bill showed only a $10–$15 minimum delivery charge—so why did Month 12 hit you with a $2,400 'Annual True-Up Statement'? Because PG&E defers all cumulative Time-of-Use energy deficits, 3¢/kWh Non-Bypassable Charges (NBCs), and 4:00 PM–9:00 PM peak imports into a single 12-month balloon invoice.
How to Eliminate a $2,000+ Solar True-Up Bill With an LFP Home Battery (NEM 2.0 & 3.0 Math)
Whether you are on legacy NEM 2.0 getting crushed by 60¢/kWh 4:00 PM–9:00 PM summer air conditioning imports, or on NEM 3.0 where midday exports pay only 4¢/kWh, a single 10kWh to 14.3kWh LFP battery shifting 11 kWh per day from 1:00 PM to 5:00 PM saves $1,800 to $2,900 every single year.
Southern California Edison (SCE) NEM 2.0 & SBP Annual True-Up Reconciliation Guide
Southern California Edison (SCE) NEM bills are notoriously confusing because SCE bills Basic/Minimum Delivery Charges every month while hiding your real electricity balance under 'Tracked Energy Charges' until Month 12. Here is how to read your SCE NEM statement and optimize TOU-D-PRIME.
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.
How to Add Solar Panels in California Without Losing NEM 1.0 or NEM 2.0 Grandfathering
You bought an electric vehicle, heat pump, or pool after installing solar in 2019, and now you have a $2,200 True-Up bill. If you simply add 10 standard solar panels to your existing inverter, PG&E/SCE/SDG&E will revoke your 20-year NEM 2.0 grandfathering and force your ENTIRE house onto NEM 3.0 (dropping your export credits by 80%!). Here are the 2 legal ways to add panels while keeping NEM 1.0 / 2.0 100% intact.
California CCA Solar True-Up Traps (MCE, CleanPowerSF, SVCE, Ava, CPA & SDCP)
Over 14 million Californians now get their electric generation from a municipal Community Choice Aggregator (MCE, CleanPowerSF, Ava Community Energy, Silicon Valley Clean Energy, Peninsula Clean Energy, Clean Power Alliance, or San Diego Community Power) while PG&E, SCE, or SDG&E delivers the power. That splits your solar NEM accounting into TWO separate buckets—often with different True-Up dates!
Net Surplus Compensation (NSC) Explained: Why Utilities Pay 3¢/kWh for Excess Annual Solar
One of the biggest shocks at Month 12 True-Up happens to homeowners who generated MORE electricity than they used all year (-2,500 kWh net surplus): instead of paying you the $0.45/kWh retail rate ($1,125), the utility pays you the wholesale Net Surplus Compensation (NSC) rate of $0.03/kWh ($75)—and still bills you $190 for Non-Bypassable Charges!
California Climate Credit & AB 205 Fixed Charge ($24.15/mo): 2026 Solar True-Up Math
In pursuant to Assembly Bill 205 (CPUC Decision 24-05-028), California's investor-owned utilities are rolling out a standardized $24.15/month Base Services Charge ($6–$12/month for CARE/FERA) while lowering per-kWh volumetric electricity rates by 5¢ to 7¢/kWh. Here is how the semiannual California Climate Credit wipes out most of that fixed charge for solar owners.
Arizona APS (EPR-6) & SRP (E-27) Solar Bill Shock Audit: Crushing Peak Demand Charges
Why do Phoenix, Mesa, Chandler, Gilbert, and Scottsdale homeowners with 12 kW of solar still get hit with $240 July electric bills on Salt River Project (SRP E-27) or Arizona Public Service (APS)? Because SRP and APS use residential **30-Minute / 60-Minute Peak Demand Charges ($/kW)**: if your 5-ton AC, electric dryer, and oven run simultaneously for just 30 minutes at 6:30 PM on a cloudy monsoon afternoon, that single 14 kW spike adds $180+ to your monthly bill!
Texas Solar Buyback Bill Shock (Oncor & CenterPoint): The Hidden 5.3¢/kWh TDU Delivery Fee
Texas solar salespeople love pitching '1-to-1 Net Metering in Texas!'—only for Dallas (Oncor) and Houston (CenterPoint) homeowners to open a $165 July electric bill! Why? Because in deregulated Texas, Retail Electric Providers (REPs) only credit the Energy charge on exports while STILL charging you the 5.2¢–5.8¢/kWh Oncor/CenterPoint TDU Delivery Fee on every kWh you import at night—plus $20/month base fees and no cash-out rollovers!
