1. What are TUOS/DUOS charges?

1.1. DUOS stands for "Distribution Use of Service"

2. When should I select "DUOS & TUOS" charges type?

You can select the TUOS/DUOS input options when entering the Network Charges, as well as when entering the Demand Charges.

If your network tariff is flat-rate (i.e. doesn't vary with time or quantity) then select "DUOS & TUOS", even if doesn't have TUOS/DUOS labels.

If your bill's Network charges are flat rate without DUOS/TUOS labels, just enter the flat rate into the DUOS area.
