Time-of-use tariffs: who they suit and who they punish
Cheap night rates help flexible loads. Immobile evening peaks can make smart tariffs more expensive than flat rates.
Who benefits
EV drivers, households with timers on tanks and appliances, and people who can pre-heat or pre-cool on a schedule.
Who loses
Homes with inflexible evening cooking and heating peaks, low overnight use, and no storage. A higher peak rate can erase night savings.
Run your actual split through tariff comparison before switching.
