Comparison Between Old Tariff Vs New Tariff

Tariff B – Commercial / Industrial Sector


The Basic Calculation formula are as follows:-

The First 10 Units                         [10 Units x kVA]         x          B$0.20 cents

The Second 100 Units                  [100 Units x KVA]       x         B$0.07 cents

The Third 100 Units                     [100 Units x KVA]       x          B$0.06 cents

Remaining Units (if applicable)                                       x          B$0.05 cents



  • Monthly Power consumption (kWh)              =  26,880 kWh
  • Subscribed capacity (kVA)                              =  140 kVA


Bill charged for that particular month ::

The First 10 Units                         [10 Units x 140 kVA] x B$0.20 cents = B$280.00

The Second 100 Units                  [100 Units x 140 KVA] x B$0.07 cents = B$980.00

Remaining Units                           26,880 – [(10 x 140) + (100 x 140)] x B$0.06 cents

                                                      (26,880 – 15,400) x B$0.06 cents


Bill charged              =         B$280.00 + B$980.00 + B$688.80  =   B$1,948.80
