Kolkata Metro has emerged as a pioneer in reducing carbon footprints through its extensive use of renewable energy. As part of the Indian Railways’ goal to become a Net Zero Carbon Emitter by 2030, Metro Railway has made significant strides in increasing system efficiency by generating power from solar sources.
Current Solar Capacity Across Lines
Currently, Metro Railway operates solar plants with a total capacity of 4.2 MWp across various service buildings and carsheds. In the Blue Line, 763 KWp solar power plants have been installed at key stations, including Noapara, Dum Dum, and Belgachia. The East-West Corridor features 1519 KWp of solar capacity at Salt Lake Sector V and Central Park stations. Additionally, the Purple Line has a 1400 KWp plant at Joka Carshed, while the Orange Line has a 500 KWp plant at Kavi Shubhash.
A notable recent development is the commissioning of a 106 KWp solar plant on 15th August 2024, located at the Belgachia-Dum Dum tunnel ramp. This plant has already been generating an average of 400 units per day. These projects, executed through a Public-Private Partnership, will see the solar power developer manage the plants for the next 25 years.
Looking ahead, Metro Railway is set to install 360 KWp of additional solar plants on rooftops at Belgachia and Tollygunge quarters by the end of September 2024. These new installations will enable Belgachia quarters to operate nearly entirely on solar energy and significantly reduce the energy needs of Tollygunge quarters. Future plans include a 1500 KWp solar plant near Jessore Road
