Seems like there's plenty of deviation in North America, more even than the European grid is complaining about. Quebec and the Maritimes seem to oscillate between low and normal, and the west seems to always be a bit too fast.
- howard941 9y agoYeah you're seeing the short term variation at that site, and there's plenty of it.
