The correct answer is D. Udhampur.
A 100 kWp rooftop solar power plant was installed at Udhampur railway station in Jammu and Kashmir in 2018. The plant is expected to generate 1.2 lakh units of electricity annually, which will help in reducing the station’s electricity bill by Rs 1.2 lakh per year. The plant will also help in reducing the station’s carbon footprint by 100 tonnes per year.
The plant was installed by the Indian Railways under its Green Initiatives Programme. The programme aims to reduce the Railways’ carbon footprint and promote renewable energy. The Railways has already installed rooftop solar power plants at several railway stations across the country.
The installation of the rooftop solar power plant at Udhampur railway station is a step in the right direction. It will help in reducing the station’s electricity bill and carbon footprint. It will also set an example for other railway stations to follow.
The other options are incorrect because they do not have rooftop power plants.
