In force

The SBPDCL and NBPDCL FAQ is still on the NBPDCL home page. BERC’s 2026-27 order counts the scheme in its sales forecast. No 2026-27 document restates the 125 units.

Last checked against the official texts: 15 October 2026.

Tick what is true for your home

The check runs on your phone. We do not ask for your name, consumer number or Aadhaar, and nothing leaves your device.

Who qualifies

  • Your connection is a domestic connection, urban or rural.
  • The connection is in your own name. Tenants qualify if they are SBPDCL or NBPDCL consumers.

What you get

  • Up to 125 units a month, you pay no energy charge, fixed charge or electricity duty.
  • The 125 units scale with the days in the bill: 125 × days ÷ 30. A 40-day bill gets 167 free units.
  • Arrears from before July 2025 stay payable.

If you use more than the limit

Above 125 units you pay only for the extra units, at the subsidised rate, with duty on those units. You also pay the full fixed charge for the bill period.

How to apply

  1. The FAQ makes all domestic consumers eligible and describes no application.
  2. Read the official FAQ. Open the official page
Watch for scams. No official scheme asks you to pay a fee, give an OTP or open a link in a text message. Use only the official links on this page. If someone asks for money to "activate" free units, do not pay.

What we could not confirm

  • From 1 April 2026, smart-meter homes have time-of-day rates. These change the price of units above 125. Our estimate does not include them.
  • Our estimate does not include the duty on the units above 125.
