India clears 1,150-kV corridor to move solar power east

India has approved a 1,150-kV transmission corridor to carry solar power east, according to a report by Elets Technomedia published on 14 November 2026. The approval covers the corridor itself. The notice did not disclose the project's cost, its route, or a construction schedule.

The voltage is the story here. Most of India's bulk grid runs at 400 kV and 765 kV. A 1,150-kV line sits a step above both, and few such lines operate anywhere in the world. Higher voltage means fewer losses over long distances, which matters when the power has to travel from sunny western and central states to load centres far away.

Why the east

India's solar buildout has clustered in Rajasthan, Gujarat and parts of Madhya Pradesh and Maharashtra. Demand, though, is spread across the country, and eastern states have long drawn power from coal-heavy grids. A dedicated high-capacity line gives that region another supply route.

The corridor fits a pattern. Grid operators have been adding transmission capacity to keep pace with renewable additions, and the Central Electricity Authority has flagged transmission as a bottleneck in absorbing new solar. Lines take years to build. Solar parks come up faster.

What the approval does not settle is who pays. Transmission projects in India typically recover costs through tariffs spread across beneficiaries, and the split between central and state utilities often decides how quickly a line moves from paper to steel.

The technical bet

Running a line at 1,150 kV brings its own problems. Insulation, tower design and switchgear all get harder at that level, and the pool of suppliers with proven equipment is small. India has leaned on domestic manufacturers for lower voltages. For this one, the supply chain question is open.

There's also the matter of grid stability. A single high-capacity line carries more risk if it trips. Operators usually pair such corridors with reactive power support and backup paths, and those details aren't public yet.

The approval is a first step. Land acquisition, environmental clearance and tendering lie ahead, and each has stalled transmission projects before. The Elets report gives no date for when the corridor is expected to enter service.

For now, the record shows a government decision to build at a voltage India has barely used, aimed at a problem the grid has struggled with for years: getting solar power from where the sun is strong to where the lights are on.
