Consideration on Present and Future of Battery Energy Storage System to Unlock Battery Value

To address environmental concerns, there has been a rapid global surge in integrating renewable energy sources into power grids. However, this transition poses challenges to grid stability. A prominent solution to this challenge is the adoption of Battery Energy Storage Systems (BESS). Many countries are actively increasing BESS deployment and developing new BESS technologies. Nevertheless, a crucial initial step is conducting a comprehensive analysis of BESS capabilities and subsequently formulating policies. This paper analyzes the current roles of BESS and reviews existing BESS policies worldwide. It focuses on key markets in Asia, Europe, and the United States. Using collected survey data, we propose a comprehensive three-phase framework for policy formulation, providing insights into future policy development directions.
