The Delhi Metro Rail Corporation (DMRC) has successfully completed the relocation and reconstruction of the Park Street Electric Receiving Sub Station (RSS), a key power facility that was earlier dismantled to facilitate redevelopment under the Central Vista Project. With the upgraded substation now commissioned, full power support has been restored to existing metro corridors, while also enabling future network expansion.
The Park Street RSS was originally commissioned in 2010 during Phase II of the Delhi Metro to supply traction and auxiliary power to the Airport Express Line and the Violet Line. The facility was dismantled between 2021 and 2022 as part of Central Vista redevelopment, prompting DMRC to undertake a carefully planned relocation to maintain uninterrupted metro operations.
Reconstruction work began in 2023 at an alternate site provided by the Central Public Works Department (CPWD). DMRC confirmed that the project was completed in December 2025, with all critical electrical systems successfully installed and commissioned. The rebuilt infrastructure includes 66 kV power transformers, 66 kV gas-insulated switchgear (GIS), 33 kV panels, and 25 kV GIS panels.
The upgraded substation has been engineered to meet the current and future power requirements of the upcoming Central Vista Metro Line, which will connect Indraprastha with R K Ashram Marg. Alongside continuing power supply to the Airport and Violet Lines, additional 25 kV feeders have been integrated to support traction needs under the proposed Phase-5A expansion.
According to DMRC, the new facility incorporates several modern upgrades such as an advanced substation automation system, energy-efficient VRF air-conditioning, and LED lighting. Safety features have also been enhanced, including automated fire protection systems for transformers and electrical equipment, along with a fully addressable fire alarm network.
Designed in line with green building norms, the substation has applied for green certification. Plans are also in place to install rooftop solar power generation, underscoring DMRC’s commitment to sustainability and reducing the overall carbon footprint of Delhi’s metro network.
