India plans major transmission schemes for 12 GW of green energy in Gujarat

Two major interstate transmission system (ISTS) schemes are under deliberation to support the upcoming green hydrogen and ammonia capacities in Gujarat’s Kandla and Mundra regions. The National Committee on Transmission (NCT) is set to discuss these schemes, which have already been reviewed by the Western Region Power Committee (WRPC) earlier this year.

These schemes aim to facilitate the transfer of nearly 12 GW of green energy, with an estimated cost of around Rs 92 billion. They will primarily address the energy needs of green hydrogen and ammonia projects expected to come online in FY27 and FY28.

In Kandla, a scheme costing approximately Rs 27.75 billion is planned to meet the 2.465 GW electricity demand from green hydrogen projects developed by companies like Greenko Group, Renew Power, Welspun Group, and Ocior Energy. This scheme includes the development of a new 3×1500 MVA, 765/400kV GIS substation at Kandla, along with other supporting infrastructure.

In Mundra, Adani New Industries Ltd will require 11 GW of additional energy for its green hydrogen and ammonia projects. The transmission scheme here will be divided into two parts—Part B1 (6 GW) and Part B2 (3.5 GW)—with estimated costs of Rs 3,.93 billion and Rs 28.86 billion, respectively. These components will involve augmenting the existing 765/400kV Navinal GIS substation and establishing a new 4×1500 MVA, 765/400kV Navinal-II GIS substation, catering to the 11 GW requirement across three substations.

The implementation of these schemes is expected to be completed within 24 months, with concurrent development to ensure readiness by the time the green hydrogen/ammonia capacities are commissioned.
