Wind power peaks match power use lows

Once again, the numbers show: wind power shows up when it’s not needed, adding to consumers’ electricity bills

The IESO/Independent Electricity System Operator just released their October 2017 Monthly Market Report.

As usual, it was full of bad news.

Ontario power consumption was down 2.6% from October 2016 and was the third lowest consumption month of the 10 so far in 2017.

October 2017 was also the fourth highest month for curtailed wind* in 2017 with 37.9% (481,243MWh [megawatt hours]) curtailed, compared to May’s record curtailment of 49.3%, April’s of 42.6% and June’s curtailment of 38.1%.  History has shown wind’s generation levels in Ontario tend to always be higher in the Spring and Fall months, so this was no surprise.  What it does underscore, again, is that the months of lowest power consumption line up with wind power’s best days on the job. Power when its not needed!  Curtailment of wind in October cost Ontario ratepayers about $58 million.

On top of the wind power curtailment, Ontario also was busy exporting surplus power to our neighbours in New York, Michigan, etc. providing them with cheap power subsidized by the ratepayers of Ontario.  Net exports (exports minus imports) averaged 1,438 MW per hour so 1,069,872 MWh were delivered elsewhere.  Based on the record Global Adjustment (GA) for the month of $125.63 and the very low HOEP (hourly Ontario electricity price) of $8.75 MWh (0.088 cents.kWh) the cost to Ontario ratepayers; after recovery of the HOEP, transmission and congestion charges was approximately $107 million.

In summary, Ontario ratepayers picked up costs of curtailed wind of $58 million plus lost revenue from exports of $107 million for 1,550,000 MWh (rounded) generation of no value to them.  Those 1,550,000 MWh were enough power to have supplied 172,000 average households with power for a full year or almost 2.1 million average households with power for the full month of October.

No doubt we also spilled cheap clean hydro and steamed off emissions free nuclear while paying for idling gas plants, at the ready; to ensure power when clouds passed over solar panels and the wind refused to blow.

This all adds up to very Un-Fair Hydro Plan!

Note: “constrained” means the power was not needed so not added to the grid … but paid for anyway.

  1. Wait till you those prepay meters come online…. after they are installed you can bet there will be a drop in total hydro consumption again…. which means more cheaper hydro for NY and Michigan!!! Wait till that giant extention cord from Ontario to Pennsylvania via lake Erie starts drawing power !!!! Just more evidence of the Liberals secret energy deals A.K.A the Green Energy Export Market!!!

  2. OPG’s Q3 report shows the water for 4.5 TWh of potential hydroelectric power was spilled in the first 9 months of 2017, up from 3.9 TWh in 2016. At 750 kWh per home that would supply 666,667 homes in each of the 9 months. How long till we meet the 1,000,000 home mark? The cost of that lost power is $185 million at 4.1 cent/kWh.

  3. Should start a freehyrdometer webpage thingy…. update daily…. in the last 24 hours the green energy act and your liberal government have generously exported 42000000 kwh of power to NY and Michigan for alot less than you were overcharged…
    56000 ontario homes could have had power free for one month…. in just 24 hrs folks….. 56000 homes…. in one…. day….
