The West Bengal Pollution Control Board (WBPCB) has floated a tender for setting up 50 rooftop solar photovoltaic (SPV) power systems, each with an array capacity of 10 kW.

This will include a five-year comprehensive maintenance contract on a turnkey basis at multiple locations in the state.

The bid submission deadline is September 11, 2019. The technical bid opening date is September 13, 2019. The estimated cost of the projects is ₹30 million (~$ 418,989). The bid security or the earnest money deposit (EMD) required is ₹600,000 (~$ 8,380). The project completion time is 150 days from the date of letter of award.

Scope of Work

A brief scope of work includes the design and engineering, manufacture or procurement, testing, supply, installation, and commissioning of 50 units of the rooftop SPV projects. The work will be based on a single source responsibility and will completely cover equipment or material specified and will be executed on a turnkey basis.

Some other tasks to be undertaken include a detailed survey of the site location where the project will be established, the submission of designing and engineering report to install the power project, monitoring the project during the process of implementation and during the duration of the maintenance contract, to mention a few.

Only two-member consortiums will be allowed to bid and both the members of the bidding consortium need to be registered in India. The minimum average annual turnover of the bidder for the last three years has to be not less than ₹15 million (~$209,494) and net worth for all the three financial years has to be positive.

The bidder must have experience of design and engineering, procuring, testing, supply, installation, and commissioning of grid-connected rooftop solar PV projects of 300 kW or more during the last 15 years. Only indigenously manufactured PV modules can be used under this program.

Earlier, the West Bengal Renewable Energy Development Agency had put out a tender to set up 2 MW of grid-connected rooftop SPV projects in the institutional and residential categories.

Before this tender, the state had issued a tender to install 11 MW of rooftop solar power systems.
