Understanding your BEST Mumbai bill
Energy charge
The slab-wise price of the units consumed during the billing period. In telescopic slabs, each band is billed at its own rate.
Fixed charge
A monthly charge linked to sanctioned load, connected load, billing demand or consumer category. It applies even when usage is low.
Electricity duty
A statutory government levy. Depending on the state, it may apply on energy charges, fixed charges, or selected bill components.
FAC (Fuel Adjustment Charge)
Fuel and power-purchase adjustment. It changes more often than the base tariff and may appear as a charge or a credit.
Arrears
Unpaid balance, corrections, security-deposit adjustments or previous-cycle amounts carried into the current bill.
LPSC
Late Payment Surcharge on overdue amounts. Check the due date and pay through the official DISCOM channel to avoid it.
