The Standalone Energy Storage Market in India 1
Standalone Energy Storage Systems (ESS) are rapidly emerging as a key market, with 6.1 gigawatts of tenders issued in the first quarter of 2025 alone, accounting for 64% of the total
Large-scale energy storage systems have an important function in stabilizing the grid through balancing supply and demand. They buffer excess power during off-peak hours, when output exceeds usage, and deliver it during peak usage times when the grid needs more power.
There are several energy storage technologies available, broadly – mechanical, thermal, electrochemical, electrical and chemical storage systems, as shown below:
V, the storage capital cost would be lower: $187/kWh in 2020, $122/kWh in 2025, and $92/kWh in 2030. The tariff adder for a co-located battery system storing 25% of PV energy is estimated to be Rs. 1.44/kWh in 2020, Rs. 1.0/kWh in 2025, and Rs. 0.83/kWh in 2030; this implies that the total prices (PV system plus batter
nologies fall by 22%. In the near term, pumped storage is a cost-effective solution at 6.9 crore/MW. Further reductions in this cost could result in delayed investment in battery storage. Operational modeling of the 2030 power system shows energy storage can play a major role in providing operating reserves in the f
