Should one bother to look at the Independent Electricity System Operator (IESO) data for hour 19 on December 8th one would note Ontario’s natural gas plants thankfully produced 30.4% (6,399 MWh) of the entire hour’s generation which was just over 21,000 MWh. Without gas generation Ontarians would have experienced rolling backouts much like California does on high demand days.
While gas plants were thankfully, at the ready, our nuclear (8,510 MWh) and hydro (5,076 MWh) plants were reliant as always, generating 64.7% of the hour’s needs. Collectively those three dependable sectors produced 95.1% of the entire hour’s generation. The balance of 4.9% (1,033 MWh), largely unneeded, came from wind, and biomass as the sun had set so no solar generation was produced.
Ontario demand during the hour was a shade over 20,000 MWh so IESO exported the unneeded generation to Quebec (556 MWh), NY ((369 MWh) and Michigan (452 MWh) and thankfully because demand was higher due to the colder weather the market driven HOEP (hourly Ontario energy price) averaged $94.44/MWh meaning the cost of the surplus generation had a minor impact on costs paid by the ratepayers and taxpayers of the province.
It seems strange Ontario’s ratepayers are much better off when the sun isn’t shining or the winds not blowing hard but that is what the GEEA (Green Energy and Economy Act) brought us.
On an unusually cold day like December 8th we should be thankful for the readily available gas plant generation we have. Those gas plants (contracted to backup intermittent and unreliable wind and solar generation) ensured we would not be hampered by rolling blackouts.
So, all you municipal politicians in Ottawa, Toronto and elsewhere in the province, PLEASE tell us why you are demanding those reliable gas plants should be shut down!
