India will need nearly 19.3 trillion rupees (€187bn, $217bn) of investment to reach its ambitious target of installing 100 GW of nuclear power capacity by 2047, according to a report by a power ministry committee published on Tuesday (14 October).

The report assumes that India’s domestically developed pressurised-heavy water reactors will continue to be the mainstay technology for the sector, accounting for nearly 46% of the target. Large foreign reactors are seen as making up about 39% of the capacity. Funds needed to build local equipment-manufacturing plants will be additional, the report says.

But it says challenges need to be tackled such as the need for more private sector investment, controlling capital costs and reducing project timelines.
