In News

  • 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.
