As summer in Ontario finally arrived temperatures rose over the past few days and resulted in IESO reporting, so far in 2021, hour 18 of June 28, 2021 is the #1 peak hour with demand reaching 22,258 MW (megawatts). While that is the highest demand hour so far in 2021 it is by no means the highest peak over the past three years with September 5, 2018 at hour 18 reaching 23,240 MW.
Nuclear was operating at close to 100% capacity at hour 18 generating just over 47% of peak demand and hydro 22% of demand and operating at almost 69% of capacity. Our gas plants thankfully were at the ready generating slightly more than 26.5% of our peak demand and operating at 63% of their capacity.
The remaining generation capacity consisting of wind (4,500 MW), solar (438 MW) and biomass (238 MW) managed to only produce 13.9% of their capacity (just over 3% of demand) or a miserly 716 MW during the peak hour. In other words, they weren’t performing when we actually needed them! As a result, IESO imported power from Michigan and New York when prices hit their peak for the day of $232.79/MWh. Those two states regularly buy Ontario’s surplus power and in 2020, on average, they purchased it for $13.90/MWH. Interestingly according to the US IEA; “Natural gas accounted for 33% of the state’s (Michigan) net generation, while coal’s share declined to 27%.” What that means is we were importing fossil fuel generation. That should upset the eco-warriors and the Federal Liberals under Trudeau who want to eliminate all usage of fossil fuels and reach net-zero emissions by 2050 or perhaps they think the pain should only be inflicted on Canadians?
Looking to the future one wonders what will happen should Ontario see those 27 municipalities; (who have signed on to the Ontario Clean Air Alliance’s [OCAA] push for all gas plants to be shut down) get what they asked for. Where is the peaking power going to come from as it won’t come from intermittent and unreliable sources like wind and solar? Perhaps all the Ontario EV drivers will agree to provide all the power that gas generation previously did as envisaged by the OCAA. We can anticipate those same EV car owners will be told, as they were very recently in California, when they can’t charge their batteries or we will experience brownouts and/or blackouts.
Also, what happens if a peak demand day comes on a cold winter day in January (one did on January 21, 2019) after the 67% of homes currently using natural gas as a heating source are forced to convert to electric heat? Where will that additional electricity generation come from as EV lose a large percentage of their power in cold weather?
From all perspectives it seems the eco-warriors and our Federal government aim to punish all low and middle-income households in the province in their efforts to deliver on their religious beliefs.
Mankind cannot control the sun or Mother Nature so why is it so difficult for them to understand!
