India aims to increase its non-fossil fuel-based electricity generation capacity to 500 GW by 2030. For this, regions with high solar and wind potential need to be connected to the Inter-State Transmission System for efficient power evacuation to demand centres.

India, according to a preliminary plan released by the Central Electricity Authority (CEA), needs an investment of INR 4.75 trillion by 2027 to grow its transmission infrastructure, together with traces, substations, and reactive compensation. This projection aligns with the centre’s initiative to elevate the nationwide transmission system, facilitating the integration of renewable power capacities. The CEA has asked for stakeholder’s feedback and suggestions on its draft National Electricity Plan (Volume II) for transmission by March 26, 2024.

According to projections, India will attain 650.26 GW of energy technology capability including 235.13 GW from thermal and 206.14 GW from photovoltaic sources by 2026-2027. Furthermore, a battery power storage system (BESS) capability of 13.5 GW is also expected. India aims to extend its non-fossil fuel-based electrical energy technology capability to 500 GW by 2030. To achieve the ambitious goal, areas with excessive photo voltaic and wind potential must be linked to the Inter-State Transmission System (ISTS) for environment-friendly energy evacuation to demand centres. The plan outlines 170 transmission schemes, with an estimated cost of over INR 3.13 trillion for interstate connections and INR 1.61 trillion for intrastate projects. It also includes a groundbreaking INR 15,120 crore initiative to link the Andaman & Nicobar Islands to the mainland grid which is currently reliant on diesel and limited renewables and are poised for a green revolution. A 1,150 km undersea cable will be the key, paving the way for renewable energy integration by 2028-29.

The CEA preliminary plans contain the completion of an excessive voltage direct present (HVDC) hyperlink between Madurai, India, and New Habarana, Sri Lanka, with 2×500 MW HVDC terminals by 2026-27. India’s renewable energy sector reached a significant milestone in 2023, with 178.98 GW of installed capacity by October 31st. This, combined with 46.85 GW from large hydropower, brought the total renewable share to roughly 42% of the country’s entire energy technology capability.
