OPINION: Wind, Solar Can't Replace 24-7 San Onofre Nuke Plant

Southern California Edison in its video argues that its San Onofre Nuclear Generating Station, now shuttered for a year because of deep-running technical problems with its steam generators, is vital for the Southern California power grid.

Because the plant, when operating, provides thousands of megawatts of power at a steady rate 24 hours a day, seven days a week, it can't be replaced by renewable power sources like wind and solar energy, officials say.
