Electricity Supply

dryer mom and child Nuclear plants are the lowest-cost producer of baseload electricity. The average production cost of 2.19 cents per kilowatt-hour includes the costs of operating and maintaining the plant, purchasing fuel and paying for the management of used fuel.




 

Bringing Stability to America's Energy Mix

As an integral part of the U.S. energy mix, nuclear energy is a secure energy source that the nation can depend on. Nuclear energy is not subject to unreliable weather or climate conditions, unpredictable cost fluctuations, or dependence on foreign suppliers. In fact, nuclear energy is produced by a strong domestic and international industry, with extensive fuel supply sources.

Nuclear power plants produce electricity uninterrupted for extended periods—for as long as 24 months. They help supply the necessary level of “baseload” electricity for the electricity transmission network, or “grid," to operate. Nuclear power plants are a key element in the stability of our country's electrical grid.

 

A Tool to Meet Rising Demand

The U.S. Department of Energy forecasts that the United States will need 28 percent more electricity by 2040, less than 1 percent each year. That is a conservative estimate and below the actual growth rate of the past five decades. To meet this demand, the electric utility industry must invest between $1.5 trillion and $2 trillion in new power plants, environmental controls and transmission and distribution lines.

The 104 nuclear plants operating in 31 states produce 19.2 percent of our nation's electricity. Nuclear energy produces more electricity than any other source in Connecticut, Illinois, New Hampshire, New Jersey, South Carolina, Vermont and Virginia. The energy industry is planning to build advanced nuclear plants to meet growing electricity demand while enhancing energy independence and reducing greenhouse gases.

Worldwide, 437 nuclear power plants are operating in 30 countries, supplying 12.3 percent of the world's electricity. Seventy-one new nuclear plants are under construction in 14 countries. All of the world’s economic powers rely on nuclear energy for a portion of their electricity production.
