West Bengal Renewable Energy Development Agency (WBREDA) has invited bids to install 10 MW of rooftop solar systems in the state.
The scope of work includes design, engineering, manufacture, procurement, testing, supply, installation, and commissioning of 9 MW (900 grid-connected rooftop solar systems, each with an array capacity of 10 kW) and 1 MW (50 grid-connected rooftop solar systems, each with an array capacity of 20 kW) at various locations in West Bengal.
The successful bidder will also have to take care of the operation and maintenance activities of the project for five years.
The last date to submit the bids online is June 14, 2022. Bids will be opened on June 17.
The project’s estimated cost is ₹463.34 million (~$6.06 million).
Bidders can quote a cumulative capacity of 4 MW (360 rooftop solar systems of 10 kW each and 20 systems of 20 kW each).
They will have to submit ₹3.71 million (~$48,489) as an earnest money deposit.
The projects of different capacities will have a completion timeframe of between 170 days and 510 days.
Bidders should have experience in the supply, installation, and commissioning of solar power projects having solar pumps of cumulative capacity not less than 1.2 MW anywhere in India for any government organization during the preceding seven years. The minimum capacity of each solar system should be 5 kW, and for solar pumps, the minimum array capacity should be 5 kW.
Bidders should have a minimum average annual turnover of ₹55.61 million (~$726,823) during any three of the last seven financial years. They should have liquid assets or credit facility availability not less than ₹15 million (~$196,050).
Their average net worth in the last three financial years should be positive.
If the L1 bidder quotes a rate of 80% or less of the estimated cost of the project, then additional performance security at 10% of the tendered amount has to be submitted by the bidder in the form of a bank guarantee within 30 working days from the letter of acceptance.
Only indigenously manufactured solar modules should be used in the grid-connected rooftop solar systems under this program.
Last August, the West Bengal State Electricity Distribution Company invited bids to empanel agencies to install 50 MW of grid-connected rooftop solar projects on residential buildings.
Earlier, WBREDA had invited bids for the design, manufacturing, installation, and commissioning of 9.9 MW of rooftop solar power projects on a turnkey basis in the state.
According to Mercom’s India Solar Tender Tracker, WBREDA has so far floated tenders for 64 MW of rooftop solar systems in the state.
