As we have come to expect in Ontario, “peak demand” generally occurs on hot summer days and the hour ending at hour 17 on August 20th was the most recent occurrence coming in at # 8 of “peak demand hours” so far this year.
Demand at the above hour reached 21,569 MW and the bulk of that needed demand was supplied by Nuclear, Hydro and Natural Gas generators. At that hour gas plants supplied 25.9% (5,587 MW) of demand while wind generators managed to produce only 0.45% (98 MW) of demand and the bulk (53 MW) of that came from the Greenwich Renewable Energy Project a 99 MW station located Northeast of Thunder Bay so none of their generation was useful in the well populated areas of the province. The other 40 plus wind turbine generating stations scattered throughout the province produced only 45 MW which probably didn’t even cover their consumption during that hour.
The foregoing fact is something you will not hear from the OCAA (Ontario Clean Air Alliance) whose push is to close out gas plants. The OCAA’s push to close gas plants has reputedly been endorsed by 30 Ontario Municipalities representing over 50% of the province’s population.
In an effort to push the alarm button further the OCAA has called for all their followers to: “Please contact Ontario’s new Minister of Energy, Todd Smith, and ask him to direct the IESO to develop and implement a plan to achieve a complete phase-out of our gas-fired power plants by 2030.”
What Jack Gibbons the Chair and CEO of OCAA doesn’t seem to understand is that the events of hour 17 are frequent during the very hot days of summer and the very cold days during the winter. If Minister of Energy, Todd Smith, followed through with the OCAA’s recommendations Ontario’s ratepayers would be faced with numerous brownouts and even full blackouts during the dead of winter and the heat of summer.
I would suggest the ratepayers of Ontario should write a letter to the councils of the 30 municipalities informing them of the above facts and recommending they rescind their endorsement to shut down Ontario’s gas plants by 2030 as proposed by the OCAA.
