The Telangana State Renewable Energy Development Corporation (TSREDCO) has invited bids to empanel vendors to install 50 MW of grid-connected residential rooftop solar projects under Phase II of the Grid Connected Rooftop Solar Program of the Ministry of New and Renewable Energy.

Bids have been invited under four categories. The rooftop solar capacity under category A is 1 kW to 3 kW. The capacity for the B and C categories is above 3 kW to 10 kW and 10 kW to 100 kW, respectively. The capacity under category D is 100 kW to 500 kW.

The last date to submit bids is March 14, 2023. The bids will be opened the next day.

Bidders must submit an earnest money deposit of ₹500,000 (~$6,101). The successful bidders must submit a performance bank guarantee of ₹500,000 (~$6,101) in the form of a demand draft or ₹1 million ($12,203) as a bank guarantee within 15 days from the letter of award.

The scope of work includes identifying rooftops and beneficiaries and signing agreements with consumers at the quoted projected cost, along with clearances from the distribution companies. It also includes the design, supply, erection, testing, and commissioning of grid-connected rooftop solar systems under the capital expenditure model.

Successful bidders must commission rooftop solar systems within six months from approval or the last date of the project timeline specified by MNRE to TSREDCO, whichever is earlier. After commissioning these projects, they must provide comprehensive operation and maintenance services for five years.

Bidders must have installed and commissioned grid-connected rooftop solar projects with a minimum capacity of 200 kW in Telangana in the last five years.

Their average annual turnover should be ₹50 million (~$610,161) in any one of the last five financial years.

State-registered micro, small, and medium enterprises are exempted from the technical and financial eligibility criteria.

Bidders without any experience or the minimum required experience will not be allowed to quote the lowest price in bids. However, they will be allowed to implement rooftop solar projects, subject to their matching the lowest bid.

The solar modules used for the projects should be from the Approved List of Models and Manufacturers issued by the Ministry of New and Renewable Energy.

Last month, TSREDCO invited bids for installing and commissioning 1.14 MW of grid-connected rooftop solar systems on government buildings.
