SDG&E has some of the highest electricity rates in the United States, so high bills are unfortunately common for San Diego area residents. Understanding what drives your SDG&E bill helps you distinguish between California's inherently high rates and potential issues that need investigation.
SDG&E serves approximately 3.7 million people in San Diego and southern Orange counties. Bill fluctuations are common due to time-of-use pricing, seasonal factors, and California's unique rate structures.
California's Highest Rates
SDG&E consistently has among the highest electricity rates in the continental United States:
- Average rates of $0.35-0.45 per kWh (vs. national average of $0.13)
- Peak TOU rates can exceed $0.60 per kWh
- Even moderate usage results in high bills
These rates reflect wildfire mitigation costs, renewable energy mandates, and infrastructure investments in SDG&E's challenging terrain.
Time-of-Use Rates
SDG&E's TOU rates vary significantly by time of day:
- On-Peak (4-9 PM): Highest rates, often $0.50-0.65 per kWh
- Off-Peak: Lower rates, around $0.30-0.40 per kWh
- Super Off-Peak: Lowest rates, $0.20-0.30 per kWh
Running appliances during peak hours dramatically increases your bill.
San Diego Climate
While San Diego has a mild coastal climate, inland areas can be hot:
- Coastal areas rarely need AC, keeping bills lower
- Inland valleys (El Cajon, Escondido) get hot in summer
- Mountain and desert areas have extreme temperatures
Your location within SDG&E territory significantly affects your bill.
Quick Investigation Steps
- Compare this month's kWh to the same month last year
- Check your TOU usage breakdown (peak vs. off-peak)
- Look for the estimated read indicator
- Review the line-item breakdown
