The Central Electricity Authority (CEA) has begun planning to install transmission infrastructure to cater to the power demands of upcoming green hydrogen and green ammonia plants across seven coastal states and three inland states in consultation with the Central Transmission Utility (CTU).

About 40 GW of power is estimated to be the requirement at green hydrogen/ammonia/methanol production sites by 2032. This includes 22 GW of power requirement for Adani New Industries’ green ammonia plant at Mundra in Gujarat by 2030.

Earlier this year, the CEA had convened a meeting with transmission utilities of states having major ports with potential green hydrogen and green ammonia manufacturing to ascertain the likely production plan of green hydrogen and ammonia.

The meeting was told that green hydrogen/ammonia manufacturing is planned in the coastal states of Gujarat, Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh, Kerala, and Odisha. Production of green hydrogen/ammonia is also envisaged in Uttar Pradesh, Madhya Pradesh, and Rajasthan.

The Adani Group informed CEA that there is a potential for 16 GW of green hydrogen production in the Mundra region in Gujarat by 2030.

The CEA is estimating electricity demand of 1.5 GW from green hydrogen manufacturing in Mundra. In the first phase, it plans to establish a 4×1,500 MVA, 765/400 kV Navinal (Mundra) through Line in Line out (LILO) of Bhuj-II – Lakadia 765 kV D/C line.

The Odisha government has also proposed the establishment of a new 765 kV S/s in Gopalpur in view of upcoming green hydrogen and green ammonia plants with a cumulative demand of about 3 GW by 2025-26.

At a meeting in October chaired by Power Minister R K Singh with green hydrogen industry stakeholders, green hydrogen/ammonia/methanol project developers were asked to share year-wise planned capacities of green hydrogen and ammonia at different locations.

He also directed CTU to plan to set up substation capacity at these locations.

The Deendayal Port Authority in Kandla, Gujarat, has received 13 expressions of interest to a global call for applications to set up a 7 million metric tons per annum green ammonia plant. This was revealed at a meeting to review the progress of various maritime activities by Ports and Shipping Minister Sarbananda Sonowal.

In January this year, the government approved the National Green Hydrogen Mission to facilitate demand creation, production, utilization, and export of green hydrogen with an initial outlay of ₹197.44 billion (~$2.3 billion).
