Jyoti Structures Commissions 400 kV Gadag–II Transmission Line for ReNew Power in Karnataka

Jyoti Structures Limited (JSL), a listed engineering, procurement and construction (EPC) company specialising in power transmission infrastructure, has announced the successful completion and commissioning of the 400 kV Gadag–II transmission line project for ReNew Power in Karnataka.

The project involves the construction of 100 circuit kilometres (CKM) of twin high-temperature low-sag (HTLS) transmission lines connecting the Gadag Power Station and the Koppal Power Station. The transmission corridor passes through the districts of Gadag and Koppal, where the project team encountered challenging interior terrain, right-of-way (ROW) constraints and difficult soil conditions, including sections of black cotton soil.

The transmission infrastructure forms part of the Interstate Transmission System developed to facilitate the evacuation of renewable energy from the Koppal Solar Energy Zone, which is estimated to support a generation capacity of around 1,500 MW. The project was implemented on a Build, Own, Operate and Maintain (BOOM) model, enabling renewable electricity generated in the region to be transmitted to the national grid.

Rajesh Kumar Singh, CEO of Jyoti Structures Limited, said the successful completion of the project reflects the dedication and sustained efforts of the company’s project teams who navigated complex terrain and right-of-way challenges during execution. He added that the commissioning follows closely after the successful charging of another project for Torrent, marking the second project delivered by the company within a two-week period.

The commissioning of the Gadag–II transmission line is expected to strengthen grid connectivity for renewable energy projects in the region and support the efficient evacuation of solar power generated in the Koppal Solar Energy Zone.

As India continues to expand its renewable energy capacity, the development of reliable transmission infrastructure is considered essential to ensure that electricity generated in renewable energy zones can be efficiently transmitted to demand centres across the country. Projects such as the Gadag–II transmission line are expected to play an important role in strengthening grid stability while supporting the country’s broader transition toward a cleaner and more diversified energy mix.
