India’s clean energy transition is increasingly becoming dependent on large-scale storage deployment, with procurement shifting toward standalone energy storage system tenders that contract storage capacity without being tied to a specific renewable generation asset. These standalone tenders made up more than 71% of the total capacity tendered in India in 2025, according to the IEEFA, with standalone BESS projects accounting for 60% of this capacity. So, how will the dial move from tendering through to on-ground deployment?
India has moved from near-zero BESS deployment to over 92GWh tendered in under three years — but the gap between tendering and commissioning is now the defining challenge for the market. We hear where the Indian BESS market actually stands.
The vast majority of tendered capacity sits in the 2–4 hour range, but India’s grid balancing requirements will demand 6–8 hour and longer storage well before 2030. So just how will the longer duration technologies gain market maturity?
