Recently moved and find this house has a TOU tariff. Apparently cannot be changed to a single/flat rate. What a rip off! We can't afford to use the ducted air con we thought we would be enjoying in our twilight years as the peak rates are twice the price. You'd have to be nocturnal to make TOU work for you. I can't believe TOU rates can be forced onto a minority. Totally unfair!!! I feel we are subsidising both solar and single rate customers.
