Navigating TANGEDCO approvals requires deep regulatory knowledge, the right documentation, and persistent follow-up. We handle the entire approval process — from application to energisation — so you can focus on your project.
About This Service
Obtaining an Electricity Board (EB) connection in Tamil Nadu involves navigating a complex procedural framework governed by TANGEDCO (Tamil Nadu Generation and Distribution Corporation). The process demands accurate technical documentation, knowledge of current tariff regulations, and consistent liaison with multiple departments — from the Area Engineer level up to the Superintending Engineer's office.
Enervia Engineering Services acts as your authorised technical representative throughout this process. We prepare, submit, and track all necessary applications and drawings — ensuring your project's electrical infrastructure gets approved and energised without unnecessary delays or rejections due to documentation errors.
Whether you are setting up a new factory, expanding an industrial unit, commissioning a commercial complex, or upgrading from an LT to an HT supply, our experienced team manages every stage of the approval pipeline — ensuring complete statutory compliance at every step.
What We Do
We manage every procedural touchpoint — from the first application to the final energisation clearance.
Preparation and submission of new LT and HT service connection applications with all supporting documents as per TANGEDCO norms.
Processing applications for load upgradation, tariff category change, and conversion from single-phase to three-phase supply.
Handling HT (High Tension) connection agreements, including capacity calculations, demand assessment, and security deposit formalities.
Preparation of single line diagrams (SLD), earthing layout drawings, metering arrangement drawings, and other technical documentation required by TANGEDCO.
Active follow-up with TANGEDCO officers at the section, division, and circle levels to track application status and resolve objections.
Coordinating the site inspection by the Electrical Inspector and TANGEDCO, obtaining the Test Report, and facilitating the final energisation of the installation.
