Yesterday (November 4, 2021) for hour 18 industrial wind generation (IWT) in Ontario supplied 153 MWh out of total demand (approximately), including net exports (1,547 MW) that averaged about 18,750 MW during that hour. The 153 MWh generated by those IWT represented a miserly 0.82% of total demand at that hour despite their capacity level of 4,310 MW or about 15% of total available capacity at that hour.
For the full 24 hours IWT peak generation occurred at hour 2 when they managed to achieve 336 MWh of generation or 2.2% of total (approximately) demand. IWT have a perennial habit of generating power when it’s not needed, like the middle of the night!
Ontario’s ratepayers should be thankful we have baseload power available from our nuclear and hydro capacity coupled with the 8,378 MW of flexible gas generation. For the hour ending at 6 PM our flexible gas generated provided 4,388 MWh as many of us were perhaps cooking our supper!
Based on what happens far too frequently with grids with a high dependency on wind and solar such as California, Texas and Southern Australia they are often not generating power when its needed and causes rolling brownouts or blackouts.
A recent example of IWT on-shore and off-shore fallibilities occurred in the UK during the COP 26 Conference in Glasgow when the UK’s abundant IWT failed miserably and in order to keep the lights on they had to fire up some coal plants to meet critical demand.
Intermittent and unreliable IWT and solar are not the answer to either replacing fossil fuel generation nor bringing developing countries reliable energy generation to get them out of poverty!
