Annex IX: Valuing Hydropower Services - Phase II: Utilization of Hydropower Flexibility Capability in Evolving Energy Systems (2018 - )

Background

IEA Hydro initiated a programme (Phase I) to investigate the value of services provided by storage hydro projects through the establishment of the economic values of energy management, water management and other socio-economic services. All hydropower projects which have any form of reservoir (even diurnal storage) are multipurpose and the services analysed are potentially applicable to all projects. Historically, the broad range of energy and non-energy services provided by hydropower plants have not been explicitly valued, being part of a utility’s mission. 

Since the start of Phase I, two key issues affecting the hydropower sector have arisen; the penetration of variable renewable energy (VRE) sources has increased substantially and the potential impacts of climate change are being recognized. These dynamics pose both challenges and opportunities for hydropower and require further exploration and analysis beyond the scope of the original Annex work.  This will form the basis of Phase II.

Phase II will consider the role of hydropower in producing significant amounts of firm renewable energy and storage to support VRE’s, and providing flexible energy services to support electricity systems – collectively termed ‘hydro balancing’. Specifically, Phase II will develop an understanding two key strategic themes:

  • how hydropower will be valued in future electricity market scenarios, and
  • how hydropower will be valued under alternate climate change scenarios

Objectives

PHASE II (2018 - )
This Phase will start with a Kickoff Meeting in Brussels, 3-5 December 2018. More information here...

TASK 1 – Energy, Grid Services and Adaptation

Task 1 Objectives

  1. To present a holistic coverage of the role of hydropower in providing hydropower balancing and flexibility services to the electricity grid. This will allow hydropower developers, agencies, regulators and stakeholders to have a clear understanding of the issues and options for management and mitigation. 
  2. To highlight the important role for hydropower in new and transitioning power systems globally. This will enable the appropriate valuing (and incentivizing) of hydropower balancing and flexibility services.

    Subsets of this Objective include:
  • Clearly identifying the role of hydropower and the energy services provided in various future scenarios, 
  • Addressing issues, alternatives and options for flexibility and balancing
  • Estimating costs in providing services and subsequent benefits to the power system 

TASK 2 – Climate Change Adaptation Services:

Task 2 Objectives

  1. Understanding therole of hydropower in minimising or mitigating risks associated with a changing climate
  2. Assessing the value that hydropower provides in minimising or mitigating risks associated with a changing climate

TASK 3 – Hydropower Balancing and Flexibility Roadmap.

Task 3 Objective

To collate the outputs from Annex Tasks into a Hydropower Balancing and Flexibility Roadmap and its dissemination. 

Deliverables

PHASE I 

PHASE 1 (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. 

October 2017: PHASE I SUMMARY REPORT

VALUING HYDROPOWER SERVICES: The Economic Value of Energy and Water Management Services provided by Hydropower Projects with Storage was published in October 2017.

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:

  • Services provided to energy security, water security and sustainable development
  • Basic methodological concepts to assess the value of services
  • Suitable economic assessment approaches to quantify the value of services
  • Preliminary valuations of key energy and water management services
  • Initial assessment of the appropriate valuation methods for each service
  • Basic methodologies to estimate fair allocation of costs between various stakeholders

Methodology

1. Identify the organisations interested in participation and collaboration and the staff within these organisations who will participate.
2. Undertake a Literature Review of previous work on the topic 
3. Develop a project plan, with activities and schedule, of the work required to meet the task objectives
4. Undertake work and prepare a report on the outcomes
5. Disseminate the results

Case studies will be used to validate economic assessment methods, quantifying the added value created by a specific hydropower scheme, in a given river basin, through its various multipurpose enabling functions.
