The scope of work encompasses the design, supply, erection, testing, and commissioning of the floating solar project, as well as the construction of a dedicated high-tension line for grid connectivity.

The minimum capacity utilization factor mandated is 19%.

The project must be commissioned within 12 months from the power purchase agreement, with the operation and maintenance period extending for 25 years from the date of commissioning. Bidders must have experience in commissioning grid-connected solar power projects of a minimum cumulative installed capacity of 5 MW, including at least one project of 1 MW capacity.
