Released by India Energy Storage Alliance (IESA) and Customised Energy Solutions (CES), report projects that India will require 888 GWh of Energy Storage System (ESS) capacity by 2035-36, comprising 321 GWh of BESS.
About BESS
- Meaning: Electrochemical devices that work by converting electrical energy into chemical energy during charging process and then converting it back into electrical energy during discharging.
- Forms part of broader ESS (See infographic).
- Main categories of Batteries:
- Traditional solid rechargeable batteries where chemical energy is stored in solid metal electrodes.
- E.g. Lead Acid batteries, Lithium Ion batteries, Zinc Air Batteries, etc.
- Flow batteries where chemical energy is stored in varying types of flowing liquid electrolytes kept in tanks.
- E.g., Vanadium redox flow batteries, Zinc-iron flow batteries, zinc-bromine batteries, etc.
- Traditional solid rechargeable batteries where chemical energy is stored in solid metal electrodes.
Need for Enhancing ESS including BESS
- Sharp rise in electricity demand: India's peak electricity demand is expected to reach 300 GW next year.
- Installed Power Generation Capacity: Total Installed Generation Capacity is 520 GW comprising 52.3% of non-fossil fuel sources (Jan 2026) requiring advanced storage equipment.
- Facilitate Grid Integration: ESS provides critical ancillary services, including frequency regulation, voltage control, and black start capability.
