By 2030, the total energy requirement of the Railways is expected to increase to8,200 MW, or 8.2 GW. A small portion of the projected energy requirement 700 MW or 8.5 per cent of the total energy demand will still be sourced from non-renewable sources because of the current power purchase agreements with coal plants, says the official. The lions share 91.5 per cent will be met throughrenewable sources.

For this, the Railways will need to create a renewable energy installed capacity of 30,000 MW as solar and wind energy is not available round the clock and the generation varies region to region. Till August 2022, the installed renewable energy capacity of the Indian Railways was only 245 MW.
