To combat with the VRE problems Battery Energy Storage System has become essential apart from other ESS system Like Pumped Energy Storage etc. which is location specific if large scale storage is required. BESS is the economical and easily expandable to store small to large few kWh to MWH storage and production. It can meet the sufficiency of meeting National Determined Commitment by 2030, of 450 GW Energy generation with the help of VREs. The main constraints with this is the large space requirements , handling and disposal of waste parts as most of the items are recyclable. Besides this addressing emission of toxic gases from batteries. Safe installation of batteries are need to be ensured. The BESS has a large market with the expansion of VREs and EVs across the world as well as in Indian market. This is being done to mitigate Climate Change by reducing uses of fossil fuels and reduction go Been House Gases.
