The electricity it uses is overnight which normally would be wasted, that
is
why they offer economy 7 and 19 and 34, etc, when using overnight

The electricity isn't wasted at night.
It is just capacity that is not earning revenue at night.

Its better to reduce the daytime demand and use more of the capacity at
night.
This is why storage heaters were invented.
