The investor-owned electric utility that serves San Diego County is SDG&E. For 2021, SDG&E reported an average tiered residential retail electricity rate of $0.33/kWh, excluding low-income customers on discounted rates. For 2022, PG&E lists an average tiered residential electricity rate of $0.39/kWh.
Electric bills for residential customers of SDG&E are influenced by a number of different factors, including the higher cost of exceeding your monthly baseline allotment (if you have one), and when you use energy if you’re on a Time of Use rate where you pay a higher rate for for “on-peak” usage, typically from 4-9PM, and a lower rate for “off-peak” usage.
If you are on the California Alternate Rates for Energy (CARE) program, you receive a discount of up to 35% on your monthly electric bill, which isn’t considered in this calculation. If you are a customer of a Community Choice Aggregation (CCA) program that is responsible for generation of your electricity, your cost/kWh will differ from the rates provided by SDG&E.
Your actual electric bill could be much higher or lower based on these factors.
If we just use the published rates for SDG&E and multiply by the average monthly electricity usage per household, the average San Diego County household’s monthly electric bill in 2021 was approximately $179.
Using SDG&E’s new rates for 2022, the average San Diego County household’s monthly electric bill during 2022 will increase by $35 to $213.
By this calculation, this year San Diego County has the 38th highest household monthly electricity bill increase in dollars among California counties. Households pay about $58 less on their monthly electric bill than the average for California in 2022.
The average monthly electric bill in the U.S. is $115, the U.S. EIA reports. Using the average monthly bill of $213 per month, San Diego County households pay $98 more than the national average for electricity each month, which is 60% higher than the national household average.

San Diego County is more coastal than inland California. Coastal counties typically use 124% more electricity during a summer month (July-Oct.) than during an average month for the year, according to this study by the University of San Diego.
If you factor that in, San Diego County households use an average of 675 kWh of electricity during a typical summer month. That means the average monthly SDG&E electric bill in San Diego County for summer 2021 would be about $222.

If that holds true, the average household in San Diego County would pay $43 more per month for electricity this summer than in 2021.
That can really add up. The average electricity usage for the four-month summer season in San Diego County (July - October) is 2,700 kWh per household.
If you use the assumptions above, the average summer seasonal electric bill for San Diego County households would be $889 in 2021. For 2022, the average summer electric bill for San Diego County households could reach $1,061..
That would mean you could pay $172 more for your electricity this summer in San Diego County than last year.
This summer will be the first time that many households in California who receive a SDG&E bill are on a Time of Use (TOU) plan.
Under a TOU plan, you are charged different amounts per kWh based on when you use energy, not just on how much total energy you use. Electricity used 4-9PM on weekdays typically is considered “on-peak,” while energy used outside that five-hour period or on weekends is considered “off-peak.”
For SDG&E, the on-peak summer rate under the typical TOU plan is $0.69/kWh, and the off-peak summer rate is $0.30. Based on analysis of our internal data, we estimate that the average household in California uses roughly 33% of their monthly energy during on-peak times, and 66% during off-peak.
Using these numbers, we calculated what you can expect to pay this summer with TOU pricing.
The monthly TOU-adjusted electric bill for San Diego County households in 2022 is $290. That is $68 more per month than the same household with the same electricity usage would have paid in the summer 2021 on a tiered rate plan.
Over the course of the four months of summer, a San Diego County household can expect to pay $1,160 for electricity, which is about $271 more than you would have paid in summer 2021.
