Four firms have submitted bids for the 25 kV OHE & 33 kV power supply contract of the 65.1 km Delhi Metro Phase 4 project‘s elevated corridors after the Delhi Metro Rail Corporation (DMRC) opened technical bids on Thursday.

The bids have now been sent for technical bid evaluation which can take a couple months to complete. When that is done, the financial bids of the technically qualified bidders will be opened to reveal who’s the lowest bidder and most likely contractor.

This package is just one of the many electrification-related packages in Phase 4. Interestingly the OHE electrification package for remodeling Ajronda and Sarita Vihar Depots was also numbered DE-02. That contract was won by Salasar Techno Engineering in January 2021.
