12 Benefits of Utility-scale Energy Storage System (ESS) 12

13 Application of ESS in Each Sector 13

14 Energy storage, the future of industry 4.0 It is an approach to provide distributed energy resources throughout the energy value chain by deploying technologies close to the end users of power. It often consists of 3 elements: Decentralized Generation DG Energy Storage System ESS Smart Metering and Smart Grid 14
