Two New WPTO HydroWIRES Reports Examine Hydropower's Role in a Decarbonized Grid and Trends in Long-Duration Storage

Two New WPTO HydroWIRES Reports Examine Hydropower's Role in a Decarbonized Grid and Trends in Long-Duration Storage: WPTO released two reports under its Hydropower and Water Innovation for a Resilient Electricity System (HydroWIRES) Initiative.

• Price Formation in a Zero-Marginal-Cost World: The Role of Hydropower: This report examines the role of hydropower resources in a future decarbonized electric grid by identifying a set of research questions to improve understanding of electricity market design, price formation, and market efficiency in zero-carbon power systems.
• Compensation Mechanisms for Long-Duration Storage: This report discusses recent trends in energy-storage-related regulatory and policy initiatives to inform WPTO and other entities about key pathways to commercializing long-duration storage. Major takeaways from this report could enable development of long-duration energy storage technologies, such as pumped storage hydropower.
