AESO mismanaged situation that prompted blackouts


By Lethbridge Herald on April 17, 2024.

Editor:

Despite Premier Smith stating in a recent news briefing that the April 5th rotating blackouts were the result of not enough wind energy being online the reality is that the Alberta Electric System Operator (AESO) mismanaged this particular situation. As is predictable, the premier was dissing wind, building up fossil fuel generation and, in this circumstance, covering the AESO’s backside.

First, the grid system is not built backwards as the premier states. Wind/solar take priority when generation is available for a reason. These resources bid into the system at $0 per megawatt hour (bringing down the cost of our power) and are totally pollution free leaving our air, water, and soil clean after it has produced its energy. If a fossil fuel power plant could bid at $0 and be pollution free, we would also want that resource online as a priority too, but alas that’s not possible, is it?On April 5th there were 200 megawatts of wind operating. However, the 900 additional megawatts of wind that the AESO had forecast, but which did not materialize should have been backed up, as usual, by fossil fuel generation and it was to a degree. “Firm” generation that is always counted on by both the pPremier and the AESO unexpectedly went offline. When wind/solar come online and go offline they do so slowly; this does not happen in a sudden manner. 

When a fossil fuel plant trips offline it is an instantaneous loss of generation and there must be another plant immediately ready to take up the shortfall. Such was the case on April 5th. The AESO was relying on a “ firm” gas plant, and it tripped off. As such, there was an immediate loss of 395 megawatts and the AESO had not dispatched enough contingency reserve up take up that loss of capacity.

So, the long and the short of it is that the AESO mismanaged this situation. And, we all get it, mistakes happen, we learn from them and try to do better next time as the AESO always tries to do. However, the point is, own up to your mistakes, and don’t be deceitful by trying to place the blame on renewables.

To utilize Dave Carpenter’s quote :

“try to ascertain if Premier Smith had changed course and attempted to do something ethical”

Don’t hold your breath ….

Again, the Smith/Parker UCP/TBA cannot be trusted.

Don’t forget in your story who mandated the phaseout of coal generation … that’s right … Prime Minister Harper. But that was at a time before the Alberta government opposed everything legislated in Ottawa for the good of the nation.

But I think that’s Mr. Johnson’s point: only the ideological narrative matters.

And you do know why coal had to go, don’t you? (Hint – 1000 g CO2 per kWh generated).

R.U.Serious

Coal is bad, no argument with that!
Canada only emits 1.6% of the world GHG’s, China over 30%! If Canada shut down all fossil fuel vehicles, home heating using fossil fuels, and fossil fuel power generators at the very best we may get that down to 1% of the world GHG emissions.
China, the US and the EU emit almost 60% of the world GHG’s, yet Canada has been the focus of attacks for years. China or India get free passes! Ever wonder why?
I reiterate “Lets not blame but move forward to resolve these issues constructively.”

SophieR

Correct me if I’m wrong, but aren’t you ‘blaming’ China – the people who make our stuff?

Since you seem to like percentages,
Canada 0.5% of world population, 1.6% of emissions.
China 18% of world population, 30% of emissions.
We out-emit China by double.

What this means, is that we have some responsibility to do our share in lowering emissions. Renewable energy is one part of the effort.

Spot on comments Sophie. Your response shows that you are diligent enough to keep well-informed and use your regularly sharp critical thinking skills to analyze topics. I appreciate the wealth of information that your brief remarks can provide to these discussions. And Keilan below also is correct with his reference to “what you hear”.

There is a mountain of information on the internet if these fools would do the research but believing the lies these Reformers feed them is a lot easier, isn’t it?

SophieR

You’re too kind, ReallyReally 🙂 There are a number of people here that offer thoughtful insights on issues – like yourself.

Keilan

Hi R.U,
The reason you hear so much about Canada in terms of climate change is because that’s the country you live in. I hope that clears things up.

Fedup Conservative

Yet per capita we are one of the worse polluters in the world. Why don’t you do some research on what China is doing to help get control of their pollution. A cousin spent 14 years in China and 7 in South Korea building nuclear power plants for them to help them and they are doing far more than Alberta ever has.

The root cause is not the shut down of coal generation or the “unreliability” of renewables. It is the privatization of the electricity market long ago.

If it wasn’t for that, we wouldn’t have to be worried about generators shutting down production when renewable power is plenty and power is too cheap, because it isn’t profitable. Now the government has to artificially try to change the pricing scheme to make sure there is enough “base load”.

But some people still think “private companies are more efficient” and “privatization saves tax dollars”. But they don’t see how the companies are manipulating the markets to raise electricity prices and ends up costing everyone more. That’s really why we have new renewable energy production suspended…so the traditional players can keep making money and don’t have to worry about power being too cheap.

The good thing with high electricity prices is that many people are now getting solar panels. I am just waiting for mine to be installed. Regardless of environmental benefits, it just makes economic sense now with the high electricity prices.

great entry – thank you

how dare they shut down coal? and, i bet most egregious is that the bad ndp likely shut down “clean” coal. for shame.
