DMRC completes relocation of Park Street Electric RSS
The Delhi Metro Rail Corporation (DMRC) has completed the relocation and reconstruction of the Park Street Electric Receiving Sub Station (RSS) recently as part of the Central Vista Project. This achievement ensures an uninterrupted power supply to key metro corridors and supports upcoming infrastructure in the capital.
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 in 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 the Airport Line and Line-6, and further, an additional 25 kV feeder is provided for the traction power requirements of the 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 transformer 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 rooftop power system is planned to further enhance sustainability and reduce the carbon footprint of operations.
