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

Mumbai-based Engineering, Procurement and Construction (EPC) company Jyoti Structures Limited (JSL) has commissioned the 400 kV Gadag–II Transmission Line project for ReNew Power in Karnataka.

In a press release, Jyoti Structures said the project comprises 100 circuit kilometres (CKM) of twin HTLS transmission lines connecting the Gadag Power Station and Koppal Power Station. The transmission line passes through the districts of Gadag and Koppal, where the project team navigated challenging interior terrain, severe right-of-way (ROW) constraints, and difficult soil conditions, including stretches of black cotton soil.

The project forms part of the Interstate Transmission System (ISTS) designed 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, enabling the transmission of renewable power from the region to the national grid.

About the Project

In 2023, ReNew announced its goal to setup three ISTS transmission projects in Karnataka. These project would support the evacuation of around 5 GW of wind and solar power potential identified in Karnataka under Phase-I, with interconnection to the ISTS grid for a period of 35 years.

ReNew executed the Koppal Transmission Scheme to support the evacuation of 1,500 MW of renewable energy from the Koppal region in Karnataka. The scheme was awarded in FY22 and includes the development of a 400/220 kV substation.

Another project, the Gadag Transmission Project, consists of a 2 × 500 MVA 400/220 kV substation at Gadag, along with a 400 kV double-circuit transmission line from the Gadag substation to the Narendra New substation, and 400 kV GIS extension works at the Narendra New substation in Karnataka.

The third project involves 3 × 500 MVA 400/220 kV augmentation at the Gadag substation. It also included setting up a 400 kV double-circuit transmission line from the Gadag substation to the Koppal substation, and 400 kV AIS bay extensions at the Koppal and Gadag ends. Commercial operations for this project was expected to begin in two phases — in the last quarter of FY24 and the first quarter of FY25.

Leadership View

On the latest project commissining,  Rajesh Kumar Singh, CEO, Jyoti Structures Limited said, “The successful completion of the ReNew Power transmission line was made possible through the sustained efforts and commitment of our project teams, who worked through challenging terrain and right-of-way conditions. Coming soon after the successful charging of the Torrent project, this marks our second project delivered within a fortnight. We are grateful to our clients for their continued trust in Jyoti Structures, and we remain committed to supporting the development of reliable transmission infrastructure that enables renewable power evacuation and contributes to India’s clean energy goals."

The commissioning of the transmission line will help 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 robust transmission infrastructure plays an important role in ensuring that clean power generated in renewable energy zones can be reliably transmitted to demand centres across the country.
