Annex XIV: Management Models for Hydropower Cascade Reservoirs (2015 - present)
Designing a single hydro plant and reservoir or operating and managing existing hydro plants are complex tasks. The challenges are compounded in a cascade system with different stakeholders and different requirements. Each hydropower reservoir has impacts and/or dependencies on other upstream and/or downstream projects, yet has to be optimized for power generation and water services, and has to meet all requisite environmental, safety, and social compliances.
The primary objective of this Annex will be to address the management models that optimize the flow discharges and dispatch of the units across the fleet of cascade reservoirs. However, it should be noted that while all aspects of the operation and management of hydropower cascade reservoirs will be noted, only the specific areas of significant concern to the participants will be addressed in depth in this Annex. Other issues will be identified for completeness and possible future research and study.
Examples of both successful management models and lessons learned. The Annex will conclude with documentation and dissemination of the findings including case histories from the participating member countries.
To be determined
Workshops & Conference Sessions
To be determined
Key issues to be covered include:
• Safety compliance, specifically the routing of large floods
• Consistent management of environmental and social risk issues
• Meteorological and hydrological monitoring, modelling and forecasting, flow routing, specifically the interdependencies along the cascade
• Flow dispatch approaches for power generation optimization including coordination with other sources of generating (thermal, nuclear etc.).
• Dispatch rules for providing other energy and water services
• Operational constraints and their cumulative impacts
Enabling issues that will also be addressed include
• Communication models between cascade reservoir operators and managers
• Governance models, specifically for multiple owners and cross boundary issues
