  • June 2021 - Valuing Flexibility in Evolving Energy Markets: Current Status and Future Outlook for Hydropower (IEA Hydro Annex IX, June 2021)

Using a range of international case studies, the report presents a system-level review of how flexibility services are defined, procured, and valued in selected electricity markets, with a particular focus on the status and outlook for hydropower. 

The White Paper describes the role of hydropower and the need for flexibility in the future electricity system, aiming to provide a high-level overview of key issues with the intent of identifying priority areas for furtherin-depth reviews and analyses. As increasing shares ofvariable renewable energy  sources (VRE) are integrated into electricity systems, the need for flexibility and energy storage at timescales ranging from milli-seconds
to months arise. Hydropower is the largest source of renewable energy today, with hydropower and pumped hydro storage playing an important role in integrating and balancing VRE. 

PHASE I  (2015 - 2017 ) - COMPLETED
IEA Hydro’s work on Valuing Hydropower Services (Annex IX) included a multi-country review that investigated the many factors contributing to the full value of hydropower and its associated services.

IEA Hydro’s work on Valuing Hydropower Services (Annex IX) included a multi-country review that investigated the many factors contributing to the full value of hydropower and its associated services. It is apparent that in many jurisdictions, the multiple value chains are not always appropriately recognised. As power systems transition and hydropower adjusts to new operating conditions, utilizing new or existing technologies, IEA Hydro members believe it is essential that policy, regulatory and financial instruments evolve to appropriately recognise the important contributions that hydropower provides. Understanding these roles was an objective of the Summary Report, which covers:
