The successful bidder is expected to use polycrystalline solar PV technology for the project under the net metering system with associated distribution lines up to the metering point of Bangalore Electricity Supply Company Limited (BESCOM).

In a recent report Karnataka DISCOMs saw the highest number of rating upgrades with four out of five utilities upgraded to ‘A’ or ‘A+’, these were – Bangalore Electricity Supply Company Limited (A+), Mangalore Electricity Supply Company Limited (A+), Chamundeshwari Electricity Supply (A) Corporation Limited, and Gulbarga Electricity Supply Company Limited (A).

The project consists of setting up the solar panels at 27 sites ranging from 10 kW to 500 kW capacity based on the roof space available for the respective site. The Power Purchase Agreement (PPA) will be for 25 years.

According to the tender notice, the successful bidder will also be responsible for the recycling of the power project material after the life period.

The PPA tariff is to be discovered through a reverse bidding process with the benchmark tariff set at the rate of ₹3.07 (~$0.04324)/kWh. The selected bidders will be given eight months from the date of signing of the PPA for the completion of the projects.

Meanwhile, in August this year, the state of Karnataka emerged as the best state in India for rooftop solar projects. This was revealed in a survey report titled ‘The State Rooftop Solar Attractiveness Index’ (SARAL). According to the survey report, Karnataka’s score stood at 78.8 and was assigned A++.
