If anyone wants another example, this has data for Australia [1]. Power usage consistently peaks in the late afternoon, typically as everyone ends work for the day [2][3]. Unsurprisingly, this is also around when the price spikes.
It's worth pointing out AEMO's demand is for the grid, and residential solar typically does not show up on the grid. OpenNEM[1] uses estimates of residential solar to approximate the full load.
