Why It Matters The project strengthens POWERGRID’s role in developing transmission infrastructure for the integration of renewable energy capacity in Gujarat. With 6,500 MW of power from the Jam Khambhaliya REZ and Jamnagar to be integrated, the project will involve significant transmission infrastructure, including a new GIS substation, capacity augmentation and 765 kV transmission lines. The project’s ₹822.91 crore annual discovered tariff provides visibility into the tariff-based transmission opportunity, while the BOOT model will allow POWERGRID to develop and operate the project before transferring it as per the project framework.
