What is a Battery Energy Storage System (BESS)?

Battery Energy Storage Systems (BESS) are devices that store electrical energy generated from renewable sources, such as solar and wind power, in the form of chemical energy in batteries. The stored energy can then be used during periods of high demand, reducing the need for energy from traditional sources, such as fossil fuels. BESS can also help to balance the supply and demand of electricity on the grid and can provide backup power during outages.

Benefits of a Battery Energy Storage System (BESS)

  • Increased energy efficiency,
  • Improved grid stability, and
  • Reduced greenhouse gas emissions.

There are several types of batteries that can be used in a BESS, including

  • Lead-acid batteries,
  • Lithium-ion batteries, and
  • Sodium-sulfur batteries, among others.

The choice of battery type depends on factors such as cost, energy density, cycle life, and operating temperature. BESS can range in size from a few kilowatt-hours to several megawatt-hours and can be used in a variety of applications, including residential, commercial, and utility-scale projects.

BESS technology is rapidly evolving, and as the cost of batteries continues to decrease, the adoption of BESS is expected to grow. This growth is driven by a need to increase the reliability and stability of the electric grid, reduce greenhouse gas emissions, and support the integration of renewable energy sources.

The Government of India has given go ahead for inviting the expression of interest for installation of 1000 MWh Large Scale Battery Energy Storage System (BESS) as a pilot project.
