Nagpur Metro Rail Corporation Limited (NMRCL) has commissioned a solar power system between railway tracks at its Hingna Depot. With this, it has become the first metro operator in India to install an inter-track solar power project.
The pilot project has been developed over a 200-metre stretch and uses monocrystalline solar panels with a capacity of 50 kilowatt peak. The system has been designed to withstand vibrations caused by moving trains while utilising the space between tracks, which was earlier not being used for any productive purpose.
The electricity generated from the installation will be supplied directly to the depot’s internal power network. The system will not feed electricity into the city grid, making it a captive renewable power solution for depot operations.
According to the project details, the installation is expected to generate around 70,000 units of electricity every year. It is also projected to reduce carbon dioxide emissions by nearly 65 tonnes annually.
Although Indian Railways and the National Capital Region Transport Corporation had earlier explored inter-track solar installations, no metro rail operator in India had implemented such a system before.
The current project was studied by the Electrical Department’s Solar Energy division of the corporation and executed through a vendor. This pilot will be considered for further expansion only after its performance is reviewed.
The development comes as Nagpur Metro is expanding its network under Phase II. The expansion will extend metro connectivity towards Hingna, Kanhan, and Butibori, creating additional track stretches that could be assessed for similar renewable energy installations.
Nagpur Metro has been operational since 2019 and currently runs across 38 kilometres through two corridors. 
For now, the inter-track solar model has begun with the 200-metre stretch at Hingna Depot. Its wider adoption will depend on the performance data gathered from the pilot project.
