How to Get a New TNEB (TANGEDCO) Electricity Connection Online

8 min read · Updated 21 July 2026

Everyone in Tamil Nadu still says "EB connection", and the flow is now genuinely online: the new service connection portal (app1.tangedco.org/nsconline) takes the application, documents and payments end-to-end. One naming note up front — the distribution business of TANGEDCO (successor of the old TNEB) has been restructured as TNPDCL (Tamil Nadu Power Distribution Corporation, tnpdcl.org) — same offices, same section engineers, new letterhead. This guide walks the application, the deposits, the legal timelines and what to do when it sits still.

1. One DISCOM, whatever you call it

Unlike Delhi or Maharashtra, Tamil Nadu has a single distribution utility statewide — TNEB in old parlance, TANGEDCO on most portals, TNPDCL after the restructuring. Your local contact point is the section office (every locality has one, headed by an Assistant Engineer), and every online application still routes to it for inspection and energisation. Current LT tariffs, slabs and subsidy are on our TANGEDCO tariff page.

2. Documents — owners have it easy, non-owners use Form 5/6

RequirementAccepted documents
Identity proofAadhaar, voter ID, passport, PAN or driving licence.
Ownership proofSale deed, patta, property-tax receipt, or a court order establishing legal possession.
Non-owners (tenants, disputes)The owner's consent letter (Form 5) — or, when the owner won't sign, an indemnity bond (Form 6) with occupancy proof. The TNERC Supply Code makes Form 6 a right, not a favour.
Building completion certificateRequired from the local authority for larger/newer buildings; ordinary small residences are generally exempt under the notified norms.

The Form 5/Form 6 pair is the detail most applicants miss: supply is the occupier's right under Section 43 of the Electricity Act, 2003, and Tamil Nadu operationalised it with a standard indemnity format instead of leaving tenants to argue at the counter.

3. The application, step by step

  1. Apply online at the new service connection portal (also reachable via tnpdcl.org → Online Services): pick LT domestic (or the category you need), fill the premises details and load, and upload the documents. You receive an Application Reference Number — everything hangs off it.
  2. Pay the registration/application charges online. The payment portal (tnebnet.org/awp) logs you in with the application reference number as username and your mobile number as password — an odd convention worth knowing before you assume the login is broken.
  3. Section office inspection. The AE's team verifies the premises, wiring-readiness and feasibility.
  4. Demand for deposits and charges. Development and service-connection charges plus the security deposit (current-consumption deposit) are raised per the TNERC schedule — pay online against the same reference number.
  5. Meter installation and energisation. Your consumer number arrives — and note TN's quirk: billing is bi-monthly, so the first bill covers roughly two months.
  6. Offline fallback: the section office accepts the same application on paper, and authorised agents/e-sevai centres can file it for you.

4. What it costs

  1. Registration/application fee — nominal, paid at submission.
  2. Development + service connection charges — per-kW amounts from the TNERC Schedule of Miscellaneous Charges; a small domestic connection near the network typically lands in the low thousands of rupees, more where the line must be extended.
  3. Security deposit (CC deposit) — sized to expected consumption (bi-monthly billing makes it roughly two months' worth), refundable with interest, trued-up annually.

We skip rupee tables as always — TNERC revises the schedule, and the demand raised against your application reference number is the number that matters. Nothing beyond the registration fee is payable before you see it.

5. How long TANGEDCO can legally take

  • The central Electricity (Rights of Consumers) Rules, 2020 cap new connections at 7 days in metropolitan areas (Chennai), 15 days in other municipal areas and 30 days in rural areas after a complete, paid application.
  • TNERC's Distribution Standards of Performance set the state's own service levels and per-default compensation where extension work is genuinely required.

6. Application stuck? The escalation ladder

  1. Track online with the application reference number on the portal.
  2. Minnagam — TANGEDCO/TNPDCL's centralised consumer care: 1912 (or 94987-94987 by phone/WhatsApp). Quote the reference number and take a complaint number.
  3. The section AE, then the sub-division AEE — most stalls are a pending inspection or a materials gap that one visit resolves.
  4. CGRF → TNERC Electricity Ombudsman — the free statutory route once timelines lapse, with Standards-of-Performance compensation.

7. After the meter — check your first (bi-monthly) bill

Check the tariff category (LT I-A domestic for a home), the sanctioned load, and that the free-units subsidy (100 free units per bi-monthly cycle for domestic consumers, per the state scheme) has been applied. Remember the bill covers ~two months before concluding it's too high. Then put the units into our TNEB bill calculator — it implements the current TNERC slabs and subsidy — and compare. Our TNEB bill-reading guide decodes every line, and Bill Review checks a suspicious first bill for free.

Frequently asked questions

How do I apply for a new TNEB connection online?
Use TANGEDCO/TNPDCL’s new service connection portal (app1.tangedco.org/nsconline, also via tnpdcl.org → Online Services): choose the category, enter premises details and load, upload documents and pay the registration fee. You get an Application Reference Number; the section office inspects, you pay the demanded deposits online, and the meter follows.
What documents are needed for a TNEB new connection?
Identity proof (Aadhaar, voter ID, passport, PAN or driving licence) and ownership proof (sale deed, patta or property-tax receipt). Non-owners use the owner’s consent letter (Form 5) or an indemnity bond (Form 6) with occupancy proof. Larger/newer buildings also need a completion certificate.
Can a tenant get a TNEB connection without the owner’s signature?
Yes — Tamil Nadu’s supply code provides Form 6, a standard indemnity bond a tenant files with occupancy proof when the owner won’t sign Form 5 consent. Supply is the occupier’s statutory right under Section 43 of the Electricity Act, 2003.
How do I log in to pay TNEB new connection charges?
On the payment portal (tnebnet.org/awp), the username is your Application Reference Number and the password is the mobile number you registered — an unusual convention that catches many applicants. All demands raised against the application are payable there.
How many days does a new TNEB connection take?
Under the Electricity (Rights of Consumers) Rules, 2020: 7 days in Chennai (metropolitan), 15 days in other municipal areas and 30 days in rural areas after a complete, paid application. TNERC’s Standards of Performance add compensation where TANGEDCO defaults, with longer published timelines only for genuine line-extension work.
