DMRC Commissions Rebuilt Park Street Power Substation for Future Lines

2026-01-21

The Delhi Metro Rail Corporation (DMRC) has completed the relocation and reconstruction of the Park Street Electric Receiving Sub Station (RSS), a key power facility that had been dismantled to facilitate the Centre’s Central Vista Project. The upgraded substation has now been commissioned, restoring full power support to existing metro corridors while strengthening preparedness for future network expansion.

Originally commissioned in 2010 during Phase II of the Delhi Metro, the Park Street RSS was designed to supply both traction and auxiliary power to the Airport Express Line and the Violet Line (Line-6). The facility was dismantled during 2021–22 as part of redevelopment works under the Central Vista Project, necessitating a carefully planned relocation to ensure uninterrupted metro operations.

Reconstruction work began in 2023 at an alternate site provided by the Central Public Works Department (CPWD). DMRC said the project was completed in December 2025, with all major electrical systems reinstalled and commissioned. These include 66 kV power transformers, 66 kV gas-insulated switchgear (GIS) panels, 33 kV panels and 25 kV GIS panels.

The rebuilt substation has been designed to meet the current and future power requirements of the Central Vista Metro Line, which will operate between Indraprastha and R K Ashram Marg. Along with continuing to support the Airport Express and Violet Lines, the facility has been equipped with additional 25 kV feeders to cater to traction demands of the upcoming Phase-5A expansion.

According to DMRC, the new RSS incorporates several modern infrastructure upgrades such as an advanced substation automation system, energy-efficient VRF air-conditioning and LED lighting. Safety features have also been enhanced, including automatic fire protection systems for transformers and electrical panels, along with a fully addressable fire alarm network.

Built in line with green building norms, the facility has applied for certification. A rooftop solar power installation is also planned, underscoring DMRC’s focus on sustainability and reducing the metro network’s carbon footprint.
