I was under the impression that it is in the range of 1-2x per reactor. There are some old Swedish ones that are at 800mw, while the ones I believe the article refers to are in the ballpark of 1500mw.
Older water pressure reactors in France are 900mw/1300mw, the EPR is 1650mw. I concede it's not as dramatic an increase as I made it sound. But it should also go hand in hand with longer uptimes and better safety.
