How much power does Dresden produce?

Dresden Generating Station’s two nuclear reactors generate more than 1,800 megawatts of zero-emissions energy: enough carbon-free electricity to power more than 2 million homes.

Do nuclear power plants lose money?

One late 2018 study found that more than one-third of the 90-plus nuclear reactors throughout the U.S. were unprofitable or scheduled to close. Another study in 2017 by Bloomberg New Energy Finance found that more than half were losing money.
