Your bill's tariff hours
Shown because a plan below has "different tariff hours" ticked. Set the hours your bill's bands apply to. Click a cell to cycle Peak → Shoulder → Off-peak, or click and drag to paint. Usage in each band is assumed to be spread evenly across that band's hours, then re-priced against each plan's own hours.
