Tender Floated for Setting Up 9.9 MW of Rooftop Solar Systems in West Bengal

The West Bengal Renewable Energy Development Agency (WBREDA) has 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. The successful bidder will also have to take care of the project’s comprehensive maintenance for five years.

The project’s estimated cost is ₹405.9 million (~$5.58 million). Bidders will have to submit ₹2.8 million (~$38,514) as the earnest money deposit. The successful bidder will have to submit 10% of the tendered value as the performance bank security.

WBREDA reserves the right to alter, amend, or vary the allotment quantities of power projects as necessary, but such variation will be limited to +/- 25% of the original order.

The last date to submit the bids online is April 23, 201. Bids will be opened on April 27.


The tender is for 990 rooftop solar systems of 10 kW capacity each.

To participate in the bidding process for 330 grid-connected rooftop solar power systems, each of array capacity of 10 kW, bidders should have experience in supply, installation, and commissioning of ground-mounted or rooftop solar projects at any government institution, public sector undertakings, or government organizations having a cumulative capacity of 2.64 MW. The project should have been commissioned before the date of the issuance of the tender.

The balance work of 660 rooftop solar systems will be awarded to L2, L3, and L4 bidders equally if they agree to accept the lowest price schedule without altering the tender’s original terms and conditions. The projects must be completed in 300 days.

The bidders’ minimum average annual turnover for the best three of the last five financial years should be at least ₹40.6 million (~$558,459). They should hold liquid assets of at least ₹13.5 million (~$185,695).

Recently, the West Bengal Electricity Regulatory Commission (WBERC) issued amendments to the Cogeneration and Electricity Generation from Renewable Sources Regulations 2013. A significant amendment is the mandate of a gross metering facility for rooftop solar systems above 5 kW in capacity.

Earlier, WBREDA had issued a tender for setting up 2 MW of grid-connected rooftop solar systems under residential, institutional, and social sectors.

According to Mercom’s India Solar Tender Tracker, WBREDA has so far floated tenders for 34 MW of rooftop solar systems in the state.
