Ok, but from the utility company's POV it doesn't matter what an individual customer's peak usage is - the wires that go from the shared line to that customer have lots of headroom.
The problem is peak usage of a whole district, a whole city, or the whole grid.
An ideal customer would be one that uses 0kW during peaks and a lot of kW during off-peak hours, making the whole district look flat
