If it weren’t for operational power plants, nothing would happen when we flipped a light switch. The average annual electricity consumption for a U.S. residential utility customer is 10,766 kilowatthours (kWh), an average of 897 kWh per month.
There are about 8,084 power plants in the United States and 61 nuclear power plants. The amount of electricity that a power plant generates over a period of time depends on the amount of time it operates at a specific capacity. Most power plants do not operate at full capacity every hour of every day of the year.
