Rates status
Based on the 2026-27 tariff order (latest published data we have)
NBPDCL scored 82.02 and ranks 13 of 54 state and private distribution utilities — up a grade from the 13th report.
The rating scores the utility’s financial and operational performance — AT&C losses, billing and collection efficiency, the gap between what supply costs and what it earns, and the regulatory support the utility gets. It is not a measure of supply reliability or customer service, and it does not affect your tariff.
NBPDCL applies the same state-wide 2026-27 tariff schedule as the other Bihar DISCOMs (set by the state regulator). What differs by company is the service area, billing portal and contact details below.

Estimate your NBPDCL bill
Enter your units and sanctioned load for an itemised NBPDCL estimate. The result breaks
the bill into energy charge, fixed or demand charge, FPPA, duty,

limit — pick the one your connection actually falls under, because the rates differ
sharply between them. For commercial supply, time-of-day, solar export or arrears, the
full calculator carries every field.
NBPDCL FPPA — latest verified rate and trend
Latest verified NBPDCL FPPA (Fuel and Power Purchase Adjustment)
Typical domestic examples for a 2 kW LT Domestic (DS) connection, computed with the same engine as the calculator. Use them as a quick sanity check; your actual bill changes with sub-category, arrears, FPPA, duty and billing-period length.
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.
FPPA (Fuel and Power Purchase Adjustment)
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.
