TEDA Floats Tender For Installing 20 MW Rooftop Solar Systems Across The State

The installation and commissioning of 20 MW of grid-connected rooftop solar systems on state-owned buildings, industrial facilities, and educational institutions have been put out to bid by the Tamil Nadu Energy Development Agency (TEDA). 


The deadline for proposal submissions is February 15, 2023, which will be opened on the same day.


The project is expected to cost Rs. 1.2 billion, and the capital expenditure model will guide the development of the projects.


As a bid processing fee, bidders must provide Rs. 25,000 + 18% GST, along with a bid security deposit of Rs. 10 million. The winning bidder is additionally required to provide a sum equal to 10% of the contract’s total value as a performance security.


The winning bidder will be responsible for 5 years of project operation and maintenance (O&M).

Grid-connected rooftop solar systems will be connected to the local utility via a net metering arrangement, whereby the utility will credit the beneficiary’s monthly bill for any extra energy generated and not used.

The Ministry of New and Renewable Energy’s Approved List of Models and Manufacturers should be utilized to source the solar modules that will be used in the project.

Under typical testing conditions, the modules should have a rating of 535 Wp or above, and an efficiency of at least 20%.

More than 90% of the claimed efficiency should be covered by a performance warranty for the solar modules for the first 10 years, and more than 80% for the next 15 years.

Additionally, the performance warranty for the modules should cover more than 97% of the specified efficiency in the first year after installation. Module degradation shouldn’t exceed 0.7% annually.

In the event that the developer is unable to complete the project by the deadline, liquidated damages on a daily basis, computed for the performance security over a five-month period, would be assessed, up to a maximum of 10% of the contract value. 

The project will be abandoned after a nine-month delay, and the entire performance bank guarantee (PBG) sum would be renounced.
