As per the International Renewable Energy Agency’s (IRENA) renewable energy (RE) Statistics 2026 (data as on December, 2025), India stands 3rd globally in RE with an installed capacity of 250 gigawatts (GW) (solar and wind). India has added RE at a record speed “ 178.88 GW in the past five years and another 100 GW would be added by 2030. Reportedly, there is a lack of storage facility to store the produced RE and hence the usage drops. The excess availability of RE is like that of the Food Corporation of India which chronically has a shortage of silos to store a windfall of abundant grains. The Centre is readying a financial support scheme for long-duration energy storage (LDES) technologies. The Ministry of Power and Heavy Industries has proposed ‘India Battery Storage Vision 2047,’ which would commence from the fiscal year 2028. The LDES can supply power for eight or more hours while battery energy storage systems (BESS) can supply power for one to four hours. The LDES is pricey and takes time to implement, unlike lithium-ion BESS, but the Ministry is planning pilot projects to test the technology across different grid conditions.
