Yesterday April 15th was Good Friday, an official holiday and most businesses were closed. What that means is energy demand was low as is often the case during most Spring days. As it turned out peak demand occurred just before supper time during the 5 PM hour and was only 14,292 MW which Ontario’s nuclear and hydro facilities could have easily provided.
The day was also pretty windy with some sunny periods sprinkled in, meaning both of those energy sources were generating power. The foregoing is particularly noticeable from the IESO’s (Independent Electricity System Operator) Data and Capability Report for the day as it clearly indicates the wind was blowing and those IWT (industrial wind turbines) were generating lots of unneeded electricity. It is also obvious much IWT generation was also being curtailed.
The amount of IWT generation accepted into the grid was just shy of 53,000 MWh and curtailed generation was about 32,500 MWh. Collectively at a cost of $135/MWh for what was accepted plus the $120/MWh for curtailed wind; we ratepayers are obliged to accept (first to the grid rights embedded in the contracts), the costs came to approximately $11,060,000 for both. If that happened every day in a year the cost would be in excess of $4 billion for unneeded power.
As noted above because peak demand was low and generation was much higher than needed, IESO were busy selling (actually giving it away) it to our neighbours in Michigan, NY and Quebec to avoid blackouts. The exports for the full day amounted to just over 64,000 MWh and those were sold for the average HOEP (hourly Ontario electricity price) of $1.11/MWh. If one rightly assumes the exports were all either IWT generated electricity or occurred because of IWT generation (plus 1,900 MWh of solar); the cost of what was exported was about $217.00/MWh making the cost to us Ontarians over $13 million for just one day.
This continuing mess was created by the Ontario Liberal Party during the McGuinty/Wynne era, is being expanded on by the Federal Liberal Party under Justin Trudeau and the Ontario Conservative Party under Doug Ford has done nothing to stop it!
We need politicians to admit and recognize the push for “net-zero” and the “green economy” will destroy the Canadian economy and drive people into energy poverty as just one Spring day in the life of Ontarians demonstrates.
