NEW DELHI (Metro Rail News): The Chief Minister of Delhi, Smt. Rekha Gupta inaugurated a new state-of-the-art Electric Receiving Sub Station (RSS) at Park Street, which shall ensure uninterrupted power supply to key metro corridors and support upcoming infrastructure in the national capital.
The Chief Minister was briefed in detail about the benefits of this new facility constructed by DMRC in the heart of the city. The Delhi Metro Rail Corporation (DMRC) has successfully completed the relocation and reconstruction of this Electric Receiving Sub Station (RSS) at Park Street as part of the Central Vista Project of the Government of India.
The Park Street RSS was originally constructed in 2010 during Phase‑2 of the Delhi Metro to supply power to the DMRC Airport Line and Line‑6 (Violet Line). During 2021–22, the facility was dismantled to facilitate the construction of the Central Vista Project. Reconstruction of a new RSS commenced in 2023 on alternate land provided by CPWD, culminating to its completion in December 2025, duly accounting for the power requirement of the Central-Vista Metro line from Indraprastha to R K Ashram Marg.
All major existing electrical equipment has been re‑erected and commissioned, including 66 kV Power transformers, 66 kV GIS panels, 33 kV panels, and 25 kV GIS panels. The new combined RSS will supply power to the Metro Trains and Stations of Airport Line, Line‑6, and further, Additional 25 kV feeders are provided for Traction Power requirements of upcoming Central Vista Metro Line (Indraprastha to R K Ashram Marg) under its Phase-5A Expansion Project.
The new RSS facility has been constructed as per the latest standards, incorporating an upgraded Substation Automation System, Energy‑efficient VRF (Variable Refrigerant Flow) Air‑conditioning and LED lighting. Advanced safety measures include Automatic Fire Protection Systems for transformers protection and Electrical Panels, including a fully Addressable fire alarm system to ensure operational reliability.
The new RSS has been designed in line with Green Building compliance standards, and a certification has been applied for it. In addition, a Solar Roof top power system is planned to further enhance sustainability and reduce the carbon footprint of operations.
The completion of the Park Street RSS under the Central Vista Project of the Government of India marks another step in DMRC’s commitment to modern, safe, and sustainable infrastructure, ensuring reliable power supply for Delhi Metro’s expanding network.
