- The Delhi Power Minister inaugurated a 20-MW Battery Energy Storage System (BESS) at Kilokari, South Delhi .
Battery Energy Storage Systems (BESS)
- Battery Energy Storage Systems (BESS) are large-scale batteries used to store energy from renewable sources like solar and wind for later use.
- They vary in size, design, and technology, and play a crucial role in making green energy more reliable and flexible.
- They can also feed excess power back to the main grid.
- There are three main types: Pre-packaged battery modules (just batteries), pre-packaged systems (batteries plus components like chargers or inverters), and custom-made battery banks (individual batteries assembled with additional components).
BESS in Delhi
- It is the largest utility-scale system in South Asia and India’s first commercially approved energy storage system.
- The 40 MWh system enhances grid stability, reduces peak load stress, integrates renewable energy, and optimizes power purchase costs.
- It uses Lithium Iron Phosphate (LFP) technology, known for safety and thermal stability, and operates efficiently under Delhi’s varied weather conditions.
Need for Battery Energy Storage Systems (BESS) in India
- Integrating Renewable Energy into the Grid: India has ambitious goals of 500 GW of non-fossil capacity by 2030 and net zero by 2070. BESS stores surplus energy during peak generation (e.g., daytime solar) and releases it during demand spikes (e.g., night or cloudy days).
- Reducing Grid Congestion and Curtailment: BESS can decongest the grid, prevent curtailment, and increase utilization of RE infrastructure.
- Supporting Round-the-Clock (RTC) Renewable Power: India is pushing for RTC green power tenders, where RE + storage competes with coal in reliability.
- Enabling Electric Mobility and Charging Infrastructure: BESS can power fast-charging stations, reduce grid stress from EV loads, and enable vehicle-to-grid (V2G) integration.
- Economic Opportunity and Innovation: India has launched a Production-Linked Incentive (PLI) scheme for Advanced Chemistry Cell (ACC) batteries worth ₹18,100 crore that can help in domestic manufacturing & create green jobs.
