Pumped storage hydropower is a proven technology currently accounting for over 90 per cent of the world’s utility-scale energy storage applications. With the rapid growth of renewables across Asia and the Pacific, pumped storage hydropower will have an increasingly important role in integrating variable renewables and ensuring power system reliability. In many of the developing economies in the region, energy storage markets are still nascent yet there is vast potential for development.

The side event will bring together policymakers, investors, project developers, and experts to discuss and explore the need for long-duration energy storage, set out the technology options available and what policy and regulatory changes are needed in the context of Asia-Pacific.

This session builds upon findings from the International Forum on Pumped Storage Hydropower, a government-led initiative led by IHA and U.S. Department of Energy that brings together over 70 organizations, 13 national governments, multilateral development banks and the International Renewable Energy Agency (IRENA), with the Asian Development Bank, India, Indonesia and Sri Lanka on its Steering Committee. It will deliver its recommendations in September 2021. It is expected that many of the recommendations of the Forum will be cross-cutting and be applicable to other long-duration storage technologies.


At this event, you will hear:

  • How long duration energy storage, such as pumped storage hydropower, can meet a range of energy needs in Asia-Pacific
  • The scale of energy storage needs and the untapped potential for pumped storage hydropower in the region.
  • The policy and market mechanisms necessary to provide revenue certainty and de-risk investment for the deployment of long duration energy storage.
  • Experience and expert insights on the challenge and opportunities for pumped storage hydropower.

About Organizers

The International Forum on Pumped Storage Hydropower is a government-led multi-stakeholder platform to shape and enhance the role of pumped storage hydropower in future power systems co-chaired by the U.S. Department of Energy and the former Prime Minister of Australia Hon. Malcolm Turnbull.

The Forum brings together 13 governments – the USA, Austria, Brazil, Colombia, Estonia, Greece, India, Indonesia, Israel, Morocco, Norway, Sri Lanka and Switzerland - international financial institutions, International Renewable Energy Agency (IRENA), and over 70 organisations, including energy companies, academia and NGOs to develop guidance and recommendations on how sustainable pumped storage hydropower can best support the energy transition.

International Hydropower Association (IHA) acts as the secretariat to the Forum.
