This project will develop frameworks, evaluation methodologies and tools to identify hydropower’s contribution to grid reliability and resilience, especially in the seconds to hours’ time frame. These methods will be demonstrated in this project through various use cases and will be provided to industry as guidance for understanding and evaluating hydropower’s role in reliability and resilience of the evolving electric grid. The outcomes of this work will shed light on the critical role that hydropower will play in the future grid and improve understanding of hydropower’s role in providing different services to support grid resiliency.
