The Solar Energy Corporation of India (SECI) has floated a tender for setting up 1,200 MW of interstate transmission system (ISTS)-connected wind-solar hybrid power projects (Tranche-V) across India. The minimum capacity for each project should be 50 MW. A bidder’s overall project allocation capacity would be limited to 1,200 MW. The planned date of commissioning for the projects is 18 months after the power purchase agreement’s effective date. The bid submission deadline is December 6, 2021. The hybrid projects must be built for interconnection with the transmission network of the central transmission utility at a voltage level of 220 kV or above.
A hybrid power project, as defined by this tender, is one that consists of two components: one solar and one wind power project. The rated installed project capacity of the two components must be at least 33 per cent of the contracted capacity. Only wind turbine models specified in the Revised List of Models and Manufacturers provided by the Ministry of New and Renewable Energy will be allowed for deployment in order to ensure only high-quality systems are installed.
Earlier this month, the SECI awarded capacities to Hindustan Thermal Projects, Greenko Energies, ReNew Samir Urja, Power Mech Projects and JSW Neo Energy in its auction for the supply of 2.5 GW of round-the-clock (RTC) power from grid-connected renewable energy projects, complemented with power from coal-based thermal projects. The lowest tariff quoted in the tender was Rs 3.01 per kWh by Hindustan Thermal Projects.
