SDG&E Has California's Highest Rates

Your battery pays for itself by avoiding these peak prices

Rate Period
Summer (Jun-Oct)
Winter (Nov-May)
Peak (4pm-9pm)
69.65¢/kWh
62.20¢/kWh
Off-Peak
47.56¢/kWh
54.02¢/kWh
Super Off-Peak
38.82¢/kWh
44.93¢/kWh

A battery stores your cheap solar energy and uses it during expensive peak hours.
That's a 30¢+ spread every single day.

💰 How SDCP Dispatch Payments Work

⚡
Install Battery
Get SDCP rebate ($250-500/kWh) when you install
🔋
Discharge at Peak
Battery discharges 50%+ during 4-9pm weekdays
💵
Earn Payments
Receive $0.10/kWh for energy dispatched

Example: 13.5 kWh Powerwall × 50% × $0.10/kWh × 250 days = ~$169/year in ongoing payments

Example: Tesla Powerwall 3 in San Diego
