Monthly electricity bills are a product of how much electricity you use per month and the rate you pay for electricity. In Contra Costa County, CA, the average monthly electricity bill for residential consumers is $174/month, which is calculated by multiplying the average monthly consumption by the average rate for electricity: 722 kWh * 24 ¢/kWh.
Electricity bills are designed to cover all of the costs of producing the electricity that you use, of running and maintaining the electrical grid, and of any public benefit funds that promote things like clean energy and energy efficiency. These costs are rolled into both fixed charges (i.e., monthly customer chargers) and variable charges (i.e., ¢/kWh that you use). While fixed charges will remain the same from month to month, the portion of variable charges on your bill each month will change based on how much electricity you use. As a result, there are two ways to reduce your bills: by either using less electricity or by reducing the cost of electricity, by installing solar for instance.
The easiest way to compare the cost of electricity from one region to another is to look at the electricity rate. Residential rates in the U.S. range from 6 ¢/kWh to 42 ¢/kWh depending upon where you live, what types of power plants provide your electricity, and when during the day or year you’re consuming electricity.
The average residential electricity rate in Contra Costa County, CA is 24 ¢/kWh, which is 5% lower than the average electricity rate in California of 25.40 ¢/kWh. The average residential electricity rate in Contra Costa County, CA is 57% higher than the national average rate of 15 ¢/kWh.
Solar panel systems help you save money by reducing your monthly electricity bills.
