Adani commissions India’s largest inter-regional 765 kV transmission line

Adani Energy Solutions Ltd (AESL) announced that it has fully commissioned the 765kV Warora Kurnool transmission link, spanning 1,756 circuit kilometers across Maharashtra, Telangana, and Andhra Pradesh.

The project will strengthen the national grid to ensure a seamless power flow of 4.5 GW between the Western and Southern regions. It will strengthen the southern region grid and support large-scale integration of renewable energy generation.

The project, Warora Kurnool Transmission Ltd (WKTL), provides an additional inter-regional alternate current link for import into the southern region, i.e., Warora-Warangal and Chilakaluripeta-Hyderabad-Kurnool. It involved the laying of a 1,756 ckm transmission line traversing across Maharashtra, Telangana, and Andhra Pradesh and the construction of a 765 kV sub-station in Warangal on a build-own-operate-maintain basis. The project was awarded on a tariff-based competitive bid (TBCB) to Essel InfraProjects Ltd in early 2016 and subsequently acquired by AESL in March 2021 following the stressed debt restructuring undertaken by lenders.

A total of 1,03,000 MT of steel was used for erecting the towers. This equals the amount of material that would be needed to set up 10 Eiffel Towers. A total of 30,154 km of the conductor was used for the transmission lines, which is comparable to making three rounds of the moon. The required conductor material is made from a specialized alloy. An engineering and execution marvel, two mid-stream towers of 102 m height each with pile foundations, was set up on the Krishna River for the first time, shared AESL.
