STN: The Mumbai Metropolitan Region Development Authority (MMRDA) has awarded Leena Powertech Engineers Pvt. Ltd. a contract worth ₹118.2 crore. The company will handle electrical works for Mumbai Metro Line 7A & 9, two important extensions of the city’s Red Line network.
Under this contract, Leena Powertech will design, supply, install, test, and commission major electrical systems. These include 33 kV and 25 kV cabling, overhead catenary systems, auxiliary power distribution, and a complete SCADA (Supervisory Control and Data Acquisition) system for both lines.
Overview of Mumbai Metro Line 7A & 9
Mumbai Metro Line 7A extends from Andheri (East) to Chhatrapati Shivaji Maharaj International Airport.
Line 9 connects Dahisar (East) to Subhash Chandra Bose Stadium through Mira-Bhayandar.
Together, the two corridors strengthen the city’s Red Line, improving connectivity between key commercial, residential, and airport areas. Once completed, Mumbai Metro Line 7A & 9 will provide faster and more efficient transport for commuters in Mumbai’s western suburbs.
Contract Details and Bidding Process
The MMRDA invited bids for the electrical package on 29 December 2023. The total project completion period is 1,640 days, which equals roughly four and a half years.
Technical bids were opened on 23 July 2025. Four companies submitted their proposals, and after technical evaluation, two were shortlisted for the financial stage.
On 29 October 2025, Leena Powertech Engineers Pvt. Ltd. emerged as the lowest bidder (L1) with a value of ₹118.2 crore. Siemens Ltd. had placed the second bid at ₹185.3 crore. The Letter of Award was issued to Leena Powertech on the same day.
Scope of Electrical Work
The contract includes the following components:

Significance of the Project
According to Mrs. Mamta Shah, MD & CEO of Urban Infra Group, this project is an important step in Mumbai’s metro electrification journey. She highlighted that Metro Lines 7A and 9 are vital for connecting dense urban clusters and transport hubs like the airport. Efficient power systems, she added, will support safe, reliable, and sustainable metro services in the future.
Once operational, these lines will improve last-mile connectivity to the airport and nearby suburbs. They are also expected to reduce road congestion and cut travel time for thousands of daily commuters.
The MMRDA continues to focus on fast-tracking project completion and timely contract awards. This approach supports its goal of creating a 337-km metro network across Mumbai by the end of this decade.
