For anyone playing with this, don't forget to try showing historical data for regions of interest that seem to have no data. Sometimes there just isn't any data, like Manitoba, but sometimes it's like Saskatchewan, which only misses live data.
FWIW, as much as Alberta contributes to the problem via their tar sands, their electrical generation still seems to be greener than Saskatchewan's.
South Australia has a huge amount of solar and wind, but relativity little storage, and basically no renewable base load (hydro, geothermal, nuclear). While the average renewable energy usage is fairly high, the instantaneous renewable usage can drop to almost 0 some days.
Solutions are being implemented, and the renewable mix is gradually improving.
