(1) An overhead line shall, with prior approval of the Appropriate Government, be installed or kept installed above ground in accordance with the provisions of sub-section (2).
(2) The provisions contained in sub-section (1) shall not apply—
(a) in relation to an electric line which has a nominal voltage not exceeding 11 kilovolts and is used or intended to be used for supplying to a single consumer;
(b) in relation so much of an electric line as is or will be within such premises in the occupation or control of the person responsible for its installation as may be prescribed.
Legal Commentary & Landmark Judgments: Section 68
Section 68 of the Act regulates overhead lines, requiring prior approval of the Appropriate Government before installing any overhead electric line above designated voltage thresholds (typically above eleven kilovolts).
Always obtain formal Section 68 prior approval from the Energy Department before commencing foundation works on high-voltage transmission lines; constructing overhead lines without Section 68 clearance renders the line vulnerable to demolition orders.
