The successful bidder will also be responsible for 25 years of operation and maintenance of the rooftop solar PV projects. Project commissioning timeline is 12 months from the award of contract.

The tendered capacity has been split into three packages; 25 MW for Raipur, 15 MW for Bilaspur and 10 MW for Durg. The size of each project will be in the range of 10 kW to 1000 kW.

The applicable project sizes are >10 – 50 kW (A), > 50 – 100 kW (B), >100 – 500 kW (C) and >500 – 1000 kW (D). A single bidder can apply for all the three packages.
