HydroWIRES Overview (Archive Only)

Research output: NRELBrochure


While hydropower and PSH can provide a host of generation and storage resources and capabilities needed for flexible operation of the changing electric grid, the specific design and operational attributes that may prove most useful within the future power system are not well understood. This uncertainty can result in plant and fleet-wide inefficiencies in how existing grid services and ancillary services are evaluated, procured, and compensated. In response to this challenge, the Water Power Technologies Office (WPTO) has launched a new grid research initiative - Hydropower and Water Innovation for a Resilient Electricity System (HydroWIRES) - to understand, enable, and improve hydropower and PSH's contributions to reliability, resilience, and integration in a rapidly evolving electricity system.
