CSREDA issues RFP for 20 MW of rooftop projects in Chhattisgarh

The Chhattisgarh State Renewable Energy Development Agency has issued a request for proposal for the installation of 20 MW of grid-connected rooftop solar systems for the sale of power under RESCO model for government buildings in the state. The scope of work includes the designing, engineering, supply, installation, testing, and commissioning of the solar systems in line with standard design and specifications. According to the tender guidelines, the successful bidders must also provide comprehensive operations and maintenance services for a period of 25 years. The tariff quoted must not exceed Rs4 per kW for government buildings. Also, the bidder must quote a levelised tariff for each of the four categories of 1 to 9 KW, 10 to 49 KW, 50 to 99 KW, and 100 to 499 KW.The last date for submission of bids is April 15, 2020.

As per Ministry of New and Renewable Energy (MNRE) statistics, the top 10 states account for nearly 80 per cent of the total installed rooftop solar capacity in the country. As of December 2019, Gujarat had the largest installed rooftop solar capacity of 416.63 MW, followed by Karnataka, Maharashtra, Rajasthan and Tamil Nadu. In August 2019, the MNRE released the results of its state rooftop solar attractiveness index, SARAL. Karnataka ranked first, emerging as the best state for setting up rooftop solar projects. The other states with high ratings include Telangana, Gujarat and Andhra Pradesh. All these states received a rating of A++ for rooftop solar attractiveness. Meanwhile, Jammu & Kashmir ranked last. According to the MNRE, the index is expected to introduce a healthy competition among states, and promote development in the rooftop solar segment. Andhra Pradesh, Tamil Nadu and Gujarat are the most attractive states for rooftop development in terms of high internal rates of return and short payback periods. Moreover, there is a considerable difference between the average grid tariff across C&I solar segments and the average rooftop tariff in these states.
