PFC Consulting has floated a tender for the development of an interstate transmission system (ISTS). The project will enable the evacuation of 5,500 MW of renewable energy from the Jam Khambhaliya Renewable Energy Zone (Phase II) and 1,000 MW from Jamnagar (Phase I). Overall, the system is expected to facilitate the integration of approximately 6,500 MW of renewable energy capacity in the Dwarka–Jamnagar region.
According to the tender guidelines, the scope of work includes setting up a 765/400 kV substation equipped with four 1,500 MVA transformers and a 400/220 kV substation with ten 500 MVA transformers, along with the required bus reactors and bays. It also involves the development of key transmission corridors for evacuating power from the renewable energy zone, including a 765 kV double-circuit line between Kalyanpur and Jamnagar and another 765 kV double-circuit line linking Kalyanpur to the Saurashtra region near Rajkot. In addition, augmentation works will be carried out at the Jamnagar substation, including the construction of a 220 kV switchyard and the installation of three 500 MVA, 400/220 kV transformers to support the integration of around 1 GW of renewable energy capacity under Phase I.
Furthermore, the project is required to be developed on a build, own, operate, and transfer basis and provide transmission services under a long-term transmission service agreement. The bidders are required to submit a bid bond of Rs 760 million. Additionally, the successful bidder is required to furnish a performance guarantee of Rs 1.9 billion.
