I'm trying to think if it was the Market Surveillance Administrator or the AESO in Alberta.... When they looked into those incidents—and also when Powerex, B.C.'s neighbour, looked into those incidents—they found layers of causes of those blackouts.
One of the layers was the very high peak demand, which you pointed out. Another layer was a number of unexpected gas-fired generation outages. Another layer, as you point out, was around wind having very low output on those days, as well as solar, of course. It was nighttime when those incidents happened.
They were forecast to have low output, but they were a bit below that. Since then, one of the findings by AESO was that they need to change the way they forecast wind and solar. That's been one positive change.
Thank you.
