How Old Are US Power Plants?

According to the U.S. Energy Information Administration (EIA), about 530 gigawatts, or 51% of all generating capacity, were at least 30 years old at the end of 2010.

The U.S. fleet of electric power generators has a very wide range of ages, dependent on technology type.

Notable findings in the report:

• 73% of all coal-fired capacity was 30 years or older at the end of 2010
• The majority of natural gas capacity is less than 10 years old
• The nations oldest power plants tend to be hydroelectric power generators
