Frequently Asked Questions
Can I apply for a new connection if I am a tenant?
Yes, tenants can apply for a new electricity connection. You will need to provide a registered lease agreement or a No Objection Certificate (NOC) from the property owner along with your ID proof and the wiring completion certificate.
Is Aadhaar card mandatory for a new EB connection?
Aadhaar is the most commonly accepted ID proof and is strongly recommended. However, other government-issued photo IDs such as Voter ID, Passport, or Driving Licence are also accepted as alternatives.
What is a wiring completion certificate and where do I get it?
A wiring completion certificate is issued by a licensed electrical contractor after completing the internal electrical wiring of your premises. The contractor must hold a valid licence from the Tamil Nadu Electrical Licensing Board (TNELB). You can find licensed contractors through your local TANGEDCO section office or TNELB’s directory.
Can I apply for a higher load later if my requirements increase?
Yes. You can apply for a load enhancement (increase in connected load) at any time by submitting a new application at your TANGEDCO section office. An additional fee will be charged based on the increase in load, and the wiring must also be checked for the new load requirement.
