Honestly, between the various grid regulators (keep in mind, that the majority of the people working there are at least P.Eng, and often with master's degrees in Electrical Engineering, in short, the exact people who "should know better").

That these people haven't been raising alarms about how close peak usage is getting to peak capacity for at least years already (ballpark 5-10 years) should almost come as a reflection of their ineptitude, or reflecting sabotage of the electrical grid.

When I was in school they told us that renewables weren't reliable enough to have as anything more of a priority than 'supplemental' power. As in, you have a base load, then you have the consistent increase in load throughout the day, and supplemental power is if those peaks get too close to the currently available capacity. Yet, here we are.
