Energy storage is one of the few technologies on track under the Sustainable Development Scenario
Energy storage deployment reached a record level in 2018, nearly doubling from 2017. Behind-the-meter storage expansion was particularly strong, almost three times that of 2017. The leading country was Korea, followed by China, the United States and Germany. New markets have emerged quickly wherever governments and utilities have created supportive mechanisms, including in Southeast Asia and South Africa, indicating that storage continues to need policy support.
