Why is my Bihar electricity bill high?

Type your last two NBPDCL, SBPDCL bills. The tool shows how much of the change comes from days, from your use, from slab lines and from free-unit limits, and what is left for other charges.

  • Monthly bills
  • Same engine as the calculator
  • Nothing leaves your device

The units, the days and the amount are all printed on the bill. The days are the dates between the two meter readings.

The tool runs on your phone. Nothing you type leaves your device.

Example: how a Bihar bill grows

Take a home on the Bihar tariff. Its use goes from 150 to 250 units in a monthly bill: that is 67% more units. The bill goes from ₹263 to ₹675: 157% more.

  • The biggest jump is at 125 units: one more unit adds about ₹164. Stay at 125 units or below if you can.

Both bills use today’s Bihar tariff and the calculator’s default options. The figures come from the same engine as the calculator.

Ten reasons a bill goes up

  1. More days in the bill. A bill for 35 days has more units than a bill for 28 days. Compare units a day, not units a bill.
  2. Higher daily use. Air conditioners, coolers, geysers, a new appliance or guests raise daily use. Use the appliance calculator to find the big users.
  3. A slab line. Above each slab line the rate goes up. A small rise in units can give a big rise in the bill.
  4. A free-units or subsidy limit. Some State schemes stop above a limit. One unit over the limit can add a large amount. See free electricity schemes.
  5. Fuel surcharge. The FPPAS in Bihar can change each month or quarter. See the fuel surcharge this month.
  6. A tariff change. A new Bihar tariff order changes the rates. See tariff changes in Bihar.
  7. An average bill before. If the meter was not read, the last bill was an average. This bill then adds the units that the average missed. Look for “average”, “RDF”, “IDF” or “provisional” on the old bill.
  8. Arrears and charges. An unpaid amount, a late payment charge or a reconnection charge goes onto the next bill.
  9. A security deposit top-up. Discoms can ask for more deposit when your use goes up. See security deposit.
  10. A meter fault. If your use did not change, you can ask the discom to test the meter. See how to read your meter and where to complain.

Questions

Why is my NBPDCL, SBPDCL bill so high this time?

Most often the bill covers more days, your daily use went up, or your units crossed a slab line or a free-units limit. Type both bills into the tool above to see which one.

Why did my Bihar bill double when my units did not?

A slab line or a scheme limit can make the bill rise faster than the units. A fuel surcharge change, arrears or an earlier average bill can also add to it.

How do I check if my bill is correct?

Use the bill checker. It compares each line of your bill with the Bihar tariff.
