What is TNEB (TANGEDCO) and how does its new connection process work?
TNEB, TANGEDCO and TNPDCL are the same single utility that supplies electricity across Tamil Nadu. The Tamil Nadu Electricity Board (TNEB) became the Tamil Nadu Generation and Distribution Corporation (TANGEDCO), and its distribution business is now the Tamil Nadu Power Distribution Corporation Limited (TNPDCL), though the portals still carry TANGEDCO branding.
Unlike states such as Delhi or Maharashtra that have several distributors, Tamil Nadu has one distributor statewide, so every TNEB new connection goes through the same tangedco new connection online process. This guide covers the documents, steps, cost and timeline for a new connection.
What documents do you need for a TNEB new connection?
For a TNEB new connection you need two core documents: an identity proof and an ownership proof. The table below lists what is accepted for a TNEB new service connection.
| Requirement | Accepted documents | Notes |
| Identity proof | Aadhaar, voter ID, passport, PAN or driving licence | Any one |
| Ownership proof | Sale deed, patta, property-tax receipt or court order | Any one |
| Tenant or non-owner | Form 5 (owner's consent letter) or Form 6 (indemnity bond) with occupancy proof | Form 6 is a statutory right under Section 43 of the Electricity Act, 2003 |
| Building completion certificate | Local authority certificate | Needed for larger or newer buildings; small residences are generally exempt |
If you are a tenant and the owner will not sign Form 5, you can still get a TNEB new service connection by filing Form 6.
How to apply for a TNEB new connection online
You apply for a TNEB new connection online on the TANGEDCO new service connection portal at app1.tangedco.org/nsconline.
- Visit the TANGEDCO portal and open the new service connection section to start your TNEB new connection online apply.
- Create an account or log in. Note: on the payment portal (tnebnet.org/awp), your Application Reference Number is the username and your registered mobile number is the password, which is an unusual convention that confuses many applicants.
- Select your district, circle and area so your application reaches the correct office.
- Choose the category of supply: domestic, commercial or agricultural.
- Enter your load details, including the connected load in kilowatts, and select single-phase or three-phase supply.
- Upload your identity proof, ownership proof and any other required certificates. The section office also accepts paper applications, and authorised e-Sevai centres can file on your behalf.
- Submit the application and note the Application Reference Number (ARN) on the acknowledgement slip.
- Pay the demand raised against your ARN online once it is generated.
You then receive updates by SMS, and you can pay your future TNEB bills on Bajaj Finance.
How to check your TNEB new service connection status
You can check your TNEB new service connection status on the TANGEDCO portal using your application number.
- Go to the TANGEDCO Bill Status page.
- Enter your service connection or application number provided during the application.
- Enter your registered mobile number.
- View the status to see the sample SMS, bill receipt or white meter card showing your progress.
This tells you where your tangedco new connection online request has reached.
What does a new TNEB connection cost for a residential property?
A new TNEB connection for a home has three cost components: a registration or application fee, service connection charges, and a refundable security deposit.
| Charge type | What it covers | When payable |
| Registration or application fee | Filing the online application | At submission on the portal |
| Development and service connection charges | The TNERC per-kW schedule, higher if a line extension is needed | After the section office inspection, payable online against your ARN |
| Security deposit (refundable) | Sized to about two months of expected consumption, as Tamil Nadu bills bi-monthly | After the inspection demand; refundable with interest and trued-up each year |
The exact amounts are set by the TNERC schedule and shown in the demand raised against your ARN. After your connection is live, pay your bills through TNEB electricity bill payment or the wider electricity bill payment page on Bajaj Finance.
How long does TNEB take to install a new meter after application?
TNEB installs a new meter within 7 days in Chennai metro after a complete, paid application. The table below shows the legal timelines by area.
| Area type | Legal timeline | Authority |
| Metropolitan (Chennai) | 7 days | Electricity (Rights of Consumers) Rules, 2020 |
| Other municipal areas | 15 days | Electricity (Rights of Consumers) Rules, 2020 |
| Rural areas | 30 days | Electricity (Rights of Consumers) Rules, 2020 |
These timelines apply after a complete, paid application, and TNERC's Standards of Performance provide compensation where TANGEDCO defaults. Longer timelines apply only where genuine line-extension work is needed, so track your TANGEDCO new connection online request and escalate if it stalls.

Obtaining a new TNEB connection has become more efficient, thanks to online processes and streamlined procedures.
Whether you are setting up a home, office, or agricultural unit, follow the steps above to ensure a hassle-free experience. With TANGEDCO’s commitment to prompt service, you will have electricity flowing in no time.
