> You cannot power down or up a nuclear plant quickly and in the summer some rivers get too hot for cooling unless you want to kill all wildlife in it. While you cannot efficiently adjust the thermal output of a nuclear plant on short notice, you can redirect the steam generated so that generators don't produce electricity. This is down somewhat regularly in Ontario; see the first group (Bruce, Darlington, Pickering): * https://www.sygration.com/gendata/today.html https://www.sygration.com/gendata/today.html Sometimes they're at 100% (numbers don't change), other times they go up and down depending on what the rest of the grid is doing. Nuclear delivers most of Ontario's caseload (see "Supply"), and while mostly steady there are fluctuations: * https://www.ieso.ca/power-data https://www.ieso.ca/power-data
