Jyoti Structures Limited (JSL), an engineering, procurement and construction company specialising in power transmission infrastructure, recently announced the commissioning of the 400 kV Gadag–II Transmission Line project for ReNew Power in Karnataka.The project comprises 100 circuit kilometres (CKM) of twin HTLS transmission lines connecting Gadag Power Station and Koppal Power Station. The line passes through the districts of Gadag and Koppal, where the project team addressed challenging terrain, right-of-way constraints and difficult soil conditions, including stretches of black cotton soil.The transmission infrastructure forms part of the Interstate Transmission System developed to evacuate renewable energy from the Koppal Solar Energy Zone, which has an estimated generation capacity of 1,500 MW. The project was implemented on a Build, Own, Operate and Maintain (BOOM) basis to enable the transmission of renewable power from the region to the national grid.Rajesh Kumar Singh, CEO, Jyoti Structures Limited, said the project was completed through sustained efforts by the company’s project teams working under challenging site conditions. He noted that the commissioning follows the successful charging of another project delivered recently and reflects the company’s continued focus on strengthening transmission infrastructure for renewable power evacuation.The commissioning is expected to enhance grid connectivity for renewable energy projects in the region and support efficient transmission of solar power generated in the Koppal Solar Energy Zone. As India expands its renewable energy capacity, transmission projects such as this play a critical role in ensuring reliable power evacuation and maintaining grid stability while supporting the country’s clean energy transition.
