India is finally seeing the emergence of a grid-scale energy storage market after years of anticipation.
This month the Solar Energy Corporation of India (SECI) invited bids for 3.6 gigawatt-hours of storage connected to 1.2 gigawatts of solar on India’s interstate transmission system, the biggest battery solicitation seen in the country so far.
The auction came hot on the heels of several other SECI solicitations. Also this month, SECI put out a call for two 150-megawatt-hour battery systems to be connected to 100-megawatt solar farms in Andra Pradesh.
Last month, meanwhile, saw SECI calling for a 42-megawatt-hour battery system to go with 14 megawatts of solar in Ladakh in northeast India. The corporation also requested bids for a 20-megawatt floating PV plant in Lakshadweep, an archipelago off the southwestern coast of India, with 60 megawatt-hours of battery storage.
The SECI auctions come on top of seven storage tenders in the last year, Bridge to India, a New Delhi-based analyst firm, said last month. Those tenders were issued by SECI and the utilities NLC India and National Thermal Power Corporation (NTPC), and amounted to 84 megawatt-hours of capacity, tied to 78 megawatts of solar PV.
