1、 Potential Benefits of High-Power, High-Capacity Batteries January 2020 United States Department of Energy Washington, DC 20585 Department of Energy | January 2020 Department of Energy | January 2020 Potential Benefits of High-Power, High-Capacity Batteries | Page i Executive Summary The ability of

2、the United States (U.S.) electric power system (i.e., the electric grid) to reliably meet customer demand is crucial to our economy and national security. The increasing adoption of variable generation technologies and dynamic changes in customer demand are creating the need for enhanced grid flexib

3、ility to ensure the continued reliability, resilience, and security of the electric power system. Batteries and other energy storage technologies that have the capability to both supply and absorb electrical power (bidirectional electrical energy storage) can provide flexibility by helping to balanc

4、e electrical supply and demand. Report Scope and Approach This report describes opportunities for high-power, high-capacity batteries to increase the resilience of the U.S. electric power system and to help integrate higher levels of variable renewable energy (VRE). These opportunities can be addres

5、sed through multiple pathways based on technology and grid architecture options that include battery storage. By describing the opportunities in terms of grid services and dimensional requirements, this report aims to align system needs with the storage options best suited to fill those needs. Dimen

6、sional requirements for storage technologies vary by duration (intra-hour, intraday, weekly, and seasonally) and discrete market applications (e.g., power reliability, demand charge management, or electric energy time shift). This report describes the suitability of viable energy storage technology
