The Telangana State Renewable Energy Development Corporation Limited (TSREDCO) has invited bidders to bid for 1-1,000 kW of grid-connected rooftop solar power projects at various government buildings across the state on a turnkey basis.

The last date for the submission of the bids is August 13, 2019, while the price bid opening date is scheduled for August 16, 2019.

The scope of work includes the design, installation, and commissioning of various capacities of grid-connected solar power projects through rate contract program under CAPEX mode with five years of comprehensive maintenance contract (CMC).

The work of the successful bidders also includes the site survey, measurement of solar isolation, procurement, and expediting of all supplies and delivery of equipment and material to each job site.

According to the tender, the selection of projects would be technologically agnostic within solar PV technology. Crystalline silicon, with or without trackers, could be installed. “Only commercially established and operational technologies can be used to minimize the technology risk and achieve the timely commissioning of the projects, states the tender.

Interested bidders should pay a sum of ₹200,000 (~$2908) as the earnest money deposit (EMD), and it will be valid for nine months.

Under the eligibility criteria, the interested bidders should be registered with TSREDCO with the requisite experience of at least 200 kW of cumulative capacity in the field of off-grid or grid-connected solar systems in the last three fiscal years.

TSREDCO expects that the interested bidders should have a turnover of not less than ₹10 million (~$145,374) during the last three financial years.

After the receipt of the work orders, the successful bidder will be expected to complete the installation of capacity between 1 to 10 kW within two months. For installations ranging between 11 to 100 kW, the work needs to be completed within 120 days. For work above 100 kW, the duration of work is six months.

The type of project includes rooftop, ground-mounted, and high raised structures with a minimum height of 10 feet along with module cleaning.

According to TSREDCO, the grid-tied solar rooftop PV power project should consist of solar photovoltaic array, module mounting structure, power conditioning unit (PCU), inverter, controls and protections, junction boxes, and switches.

The successful contractor should obtain necessary permissions and approvals from the state DISCOM and electrical inspectorate for the implementation of the project and net metering.

The tender has emphasized on indigenously manufactured solar PV modules with radio frequency identification (RFID). The product should be ‘Made in India’ with a company name and logo, serial number, and the year it was manufactured.

The solar photovoltaic modules should not be less than 250W.

Recently, Mercom also reported that TSREDCO invited bids from interested bidders for establishing 5.4 MW of rooftop solar PV projects of different capacities in Telangana under the net metering program.

Previously, in March this year, TSREDCO had issued a tender for 31.12 MW of grid-connected rooftop solar PV projects under the RESCO model with net metering. The solar PV systems were to be installed on vacant building rooftops of pump houses, reservoirs, sewage and waste treatment plants, and office buildings of Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB).
