The Energy Storage System (ESS) refers to a device that stores energy generated from renewable energy sources or existing power grids into a battery to be discharged for use later on when needed. By applying our technological expertise and that of our overseas subsidiary Doosan GridTech, Doosan Enerbility delivers total technology solutions that include the ESS, DERM-based control system software, as well as EPC and O&M services. In line with the growing trend of renewable energy at home and abroad, we plan to further expand the ESS business, with particular focus on the Australian and US ESS markets which are forecasted to grow rapidly in the coming years.
