The Tamil Nadu Energy Development Authority (TEDA) has issued a tender for the selection of bidders for the installation of 50 MW of grid connected rooftop solar systems in the state.

The rooftop solar projects will be installed atop government buildings in the state of Tamil Nadu. The bid-submission deadline is September 24, 2018.

The successful bidders will have to enter into a contract agreement with TEDA. The scope of work will broadly include the design, supply, installation, testing, and the commissioning of the rooftop solar systems. The successful bidder will also be responsible for the operation and maintenance (O&M) of rooftop solar PV systems up to 25 years.

The capacity of each project will range from 1 kWp to 500 kWp for the identified locations of the concerned buildings. One system may, however, comprise several rooftop units. These rooftop installations will also include a Tamil Nadu Generation and Distribution Corporation (TANGEDCO) net-metering facility.

TEDA has fixed the maximum bid price at ₹ 4.79 (~$ 0.069)/kWh.

To be eligible for bidding, a bidder must have installed a cumulative total solar PV capacity of not less than 50 MW in India during the financial years 2014-15 to 2018-19 and have operation and maintenance experience of at least 10 MW of solar PV system capacity in India.

In this tender, TEDA has also specified that the solar PV modules will have to be manufactured in India. The remaining system components may be procured from any source.

The bidder will have to furnish an interest free earnest money deposit (EMD) for a value of ₹25 million (~$0.36 million) for the cumulative capacity of 50 MWp.

Earlier, TEDA invited expressions of interest (EoIs) for the development of 500 MW solar park in the state.
