Siemens Wins Bangalore Metro Phase 2A & 2B’s Electrification Contract EPC5-CC

Siemens – Rail Vikas Nigam Ltd. (Siemens – RVNL JV) in February was declared as the lowest bidder for the 750V DC third rail electrification contract EPC5-CC for Bangalore Metro’s 57 km Blue Line by Bangalore Metro Rail Corporation Ltd. (BMRCL).

This new under construction line of Bangalore Metro’s Phase 2A (ORR Line) and Phase 2B (Airport Line) projects will connect Silkboard – KR Puram – Bengaluru International Airport through 30 stations on the Outer Ring Road and national highway NH-44.

Besides Third Rail traction works which will supply power to the line’s BEML trains from Package 5RS-DM, this critical systems contract includes commissioning its 33 KV distribution system, several substations & auxiliary substations, and SCADA system for the entire line.

BMRCL had invited bids for package EPC5-CC in September 2023 with an unknown estimate and 130 week (2.5 year) deadline.

Financial Bid Values

Firm	Bid (Rs. Crore)
Siemens – RVNL JV	769

Brief Scope: Engineering, supply, erection, testing and commissioning of 33 KV distribution, 750V DC third rail traction electrification including traction substations, auxiliary substations and SCADA system for Phase-2A & Phase-2B.

BMRCL’s estimate is unknown to me, so I can’t provide an assessment on the chances of a contract getting awarded. But looking at Siemens – RVNL’s bid relative to others and the time lost so far in bidding, this will definitely be awarded to them – with or without negotiations.

Here’s a more detailed scope from the tender documents of what Siemens RVNL JV’s work will entail:

• Engineering, Supply, Installation, Testing and Commissioning of 33 kV switchgear with associated works at 66/33 kV Receiving Substations.
• Engineering, Supply, Installation, Testing and Commissioning of 33 kV MV Cable network connecting various ASSs /TSSs.
• Engineering, Supply, Installation, Testing and Commissioning of 33 kV/ 415 V Auxiliary Substation equipment at Stations, wayside TSS/ASS and Depot TSS/ASS.
