In force

TNERC Order 5 of 2026 (26 May 2026) confirms G.O.(Ms) No.50 and approves the subsidy until 31 March 2027.

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 on tariff LT IA.
  • The tariff order allows one LT IA connection for each house or flat. Extra connections in the same house go to a different tariff.

What you get

  • From 10 May 2026, a home that uses 500 units or less in two months gets 200 units free.
  • A home that uses more than 500 units in two months gets 100 units free, as before.
  • TNPDCL applies the free units in each service connection’s bill. You do not apply.
  • LT IA has no fixed charge.

If you use more than the limit

At 501 units the home loses the second 100 free units at once. The bill goes up by much more than the price of one unit.

How to apply

  1. You do not need to apply. TNPDCL applies the free units in the bill.
  2. For your bill, go to the TNPDCL website. Open the official page

TNPDCL has a page to link Aadhaar to a domestic connection. No document we read makes it a condition for the free units.

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

  • We could not read the text of G.O.(Ms) No.50 itself. We use the TNERC orders that quote it.
  • No document says how the 500-unit limit applies to a home that gets a bill every month.
