record wind: what would the IESO say

Onshore and offshore wind turbines fed an all-time record of 32.6GW into the German grid on Wednesday, according to transmission operator TenneT said.

The high output forced transmission system operators to apply costly measures in order to stabilise the grid.

Since 9 November, TSOs have had to curtail 300MW of wind capacity and call up a daily amount between 200MW and 2.2GW of Germany’s winter reserve capacity to stabilise the grid.

The report on Germany, based on information from its "transmission operator" might have a related report in Ontario, which may have had record wind output recently except for the curtailments of a lot more than Germany's 300MW.

Data from Ontario's IESO indicates record wind ouptut of 3,297 megawatts for hour 16 of October 19th.

Other data indicates that earlier on the 19th, approximated 2,310 megawatts of wind was being curtailed (in hour 3).

My reporting for the day estimates over 26,000 megawatts of potential generation from contracted transmission-connected industrial wind turbines was curtailed on the 19th.

I estimate in Ontario on the 19th almost 1 in 4 megawatts of deemed or actual generation was curtailed or dumped at essentially no cost on export markets.

Germany's Tennet communicated about the challenges and costs of high wind output there.

Ontario's IESO communicated nothing.

Hurting Michigan

Image
Parker Gallant has called for the Ontario government to "shutdown the intertie line with Michigan" - in an article that notes some of my work. I feel I should offer some support as Michigan is being a lousy neighbour and it would feel therapeutic, if nothing else, to respond. I'll try to stick to data. The system operator in Ontario (IESO) data indicates the Michigan intertie is the most lucrative for exports - but that's not saying much: exports at that intertie were bought in Ontario for an average of just 1.2 cents/kWh ($12/MWh) in 2020 - but were in such high demand another 0.9 cents/kWh of congestion rent was paid. Over the past 5 years congestion rents comprise 46% of the revenue on the Michigan intertie. The IESO's insiders' committees are considering how much of  this revenue to share with the exporters instead allowing it to solely benefit internal Ontario consumers. Action #1: hell no. Issue a ministerial directive that congestion rents will only b...

Ontario's electricity system has not yet passed gas

Image
Ontario’s electricity system includes generators fueled by natural gas. This is suddenly a hot topic as a campaign lobbying councils to say no to this type of generation moves through municipalities. The “no gas” lobbying appeals to a desire to reduce greenhouse gas emissions, exploiting predictions of increased use of natural gas in generating electricity in the province. This article will explore what entities have been the key drivers of emissions in Ontario’s electricity system, the credibility of the body being cited predicting increased generation fueled by natural gas and, if all goes well, convince the reader they are not willing to decrease global carbon emissions at any cost. Background on the IESO’s pretend market My previous post reconstructed a method to estimate losses on electricity exports out of Ontario. The measure does not indicate Ontario would be better off if it didn’t export its excess, but that Ontario would be better off with data discipline and consistent me...
