(GIST OF SCIENCE REPORTER) BATTERY ENERGY STORAGE SYSTEM (BESS)

(JULY-2025)

On World Environment Day 2025, The Hindu published an article titled “Role of BESS in shaping India’s Energy Transition”, highlighting the growing importance of
Battery Energy Storage Systems (BESS) for their affordability, scalability, rapid deployment, and geographical flexibility.

A Battery Energy Storage System (BESS) is a large-scale rechargeable battery that plays a crucial role in the energy landscape.
It stores electricity, often from renewable sources like the sun and wind, when it is abundant. BESS can become a vital component in the energy landscape as demand for renewable energy and electrification grows.

Portable Power Units: Designed for flexibility and transient settings, offering a seamless charging experience. These units deliver consistent power, integrate easily with current asset and fleet management services, connect quickly to the grid, and offer high energy density in a compact and cost-effective form.
Stationary Power Units: Optimise commercial and industrial sites with a cost-effective and environmentally responsible energy solution.

Emission Reduction: Helps reduce emissions and promotes a greener grid by decreasing reliance on non- renewable sources.
Cost Optimisation: Stores energy when electricity prices are low (e.g., at night or during high renewable generation) and uses it during peak hours when prices are high, potentially reducing energy bills.
Reliable Power Source: Provides a steady and reliable source of backup power during outages or disruptions, ensuring consistent operations even if renewable sources are intermittent.
Grid Stability: Enhances grid operations by stabilising the grid, balancing demand-supply fluctuations, and enabling peak load management.
Revenue Generation: Offers the opportunity to participate in the energy market by selling surplus energy back to the grid during peak hours, transforming excess energy into revenue.
Integration with Renewables: Mitigates the variability of renewable energy, enabling their large-scale integration into power systems.
Decentralised Solutions: Supports decentralised energy solutions and microgrids, ensuring renewable energy reaches where it is needed most.
