India's power transmission infrastructure is headed for a massive investment cycle, with nearly ₹9 trillion in government-committed transmission capex expected till 2032, according to a report by Kotak Neo.

The report said the country's clean energy transition is no longer just about adding solar parks and wind farms, but also about building the grid infrastructure needed to move electricity efficiently across regions.

"India is adding 470 GW of renewable capacity. Every watt of that power needs wires, transformers, substations, and transmission lines before it can reach the grid," the report noted.

India's installed renewable energy capacity stood at 226 GW as of June 2025, nearly three times the 76 GW recorded in 2014. Over the next decade, the country is expected to add another 470 GW of solar and wind energy capacity, while power demand is projected to grow at a CAGR of 6.4 per cent till 2030, the report added.

According to the report, High-Voltage Direct Current (HVDC) transmission systems are likely to play a critical role in the transition, especially as renewable projects move farther away from consumption centres."

India's HVDC market is expected to grow from $15 billion in 2025 to $31 billion by 2035," the report said.

The report highlighted that annual transmission capex currently stands at around $8-9 billion, while large-scale projects typically take three to five years to complete, offering long-term visibility for equipment manufacturers.

It also pointed to rising demand from sectors such as data centres, railway electrification, electric vehicles, and industrial expansion, all of which will require stronger transmission and distribution infrastructure.

At the centre of the transmission buildout is Power Grid Corporation of India, whose actual capex in FY26 exceeded its revised target and reached ₹35,540 crore, the report said. The company has planned capex of ₹1.08 lakh crore between FY26 and FY28 and an estimated business pipeline of ₹3.06 lakh crore through FY32. However, the report cautioned that execution delays, land acquisition challenges, raw material price volatility and timing of HVDC orders remain key risks for the sector.

"This is not a one-time capex cycle. It is a decade-long infrastructure buildout," the report added.
