Mumbai Metro Rail Corporation (MMRC) has invited bids to install 2.8 MW of rooftop solar systems and associated support structure works on Aarey station and depot buildings of the Mumbai Metro Line 3 project.

The scope of work includes site survey, investigation, design, engineering, supply, installation, testing, and commissioning of rooftop solar systems within twelve months. The renewable energy service company (RESCO) model will be used for the projects.

Bidders should have experience in installing and commissioning solar power projects. Specifically, they must have completed grid-connected solar projects of at least 3 MW in total capacity during the last ten years. At least one of the projects should be of 750 kW.

Additionally, bidders must have completed a rooftop solar project of a minimum of 1 MW during the last ten years.

Within the last three financial years, they should have an annual turnover of at least ₹150 million (~$1.8 million) as total certified payments received for contracts in progress or completed.

The bidder needs to show that their available money after subtracting what they owe for existing contracts is at least ₹15 million (~$180,939).
