The Solar Energy Corporation of India (SECI) has announced the list of bidders for its 400 MW tender for renewable power on a round-the-clock basis. The list of bidders includes Greenko for a capacity of 400 MW, ReNew Power for 400 MW, HES Infra for 100 MW, and Ayana for 50 MW. The tender has been oversubscribed by 550 MW. SECI issued the tender in October 2019 to procure 400 MW of renewable energy on round the clock basis. The energy procured through these projects will be supplied to the New Delhi Municipal Corporation (NDMC) and Dadra and Nagar Haveli. Under this tender, solar, wind, and hybrid projects can be developed. The bidder will also have the flexibility to choose the type of storage system to be installed like battery energy storage systems, pumped storage systems, mechanical and chemical systems.
High upfront costs, low consumer awareness, lack of policy and regulatory structures, and poor project visibility have been some of the key impediments in the adoption of energy storage systems. Very few developers and utilities have paid serious attention to energy storage, despite its potential in facilitating renewable energy integration into the grid, delivering peak capacity without carbon emissions, instantly adjusting the frequency of the system, and more.
This scenario, however, seems to be changing. With battery costs falling and early adopters of energy storage liking what they have seen in initial trials, the cycle from pilot and evaluation to widespread adoption is speeding up. In the past one year, there has been a surge in the issuance of storage-based tenders, both big and small. Battery technologies have improved in terms of performance and efficiency. Tariffs too are accordingly becoming more attractive.
