The International Forum on Pumped Storage Hydropower is a government-led multi-stakeholder platform to shape and enhance the role of the 'world's water batteries' in future power systems.
Launched in November 2020 by the International Hydropower Association (IHA) and chaired by the U.S. Department of Energy, the Forum brings together governments, industry, financial institutions, academia and NGOs to share their experiences and build best practice.
Through convening three industry-led working groups, this year-long initiative will develop guidance and recommendations about how sustainable pumped storage hydropower (PSH) can best support the energy transition.
The initiative brings together 11 governments – the USA, Austria, Brazil, Estonia, Greece, India, Indonesia, Israel, Morocco, Norway and Switzerland - international financial institutions, and over 70 organisations, including leading energy companies such as including EDF, GE Renewable Energy, Voith and Hydro Tasmania.
Pumped storage hydropower (PSH) is the world's largest battery energy storage technology, accounting for over 94 per cent of installed energy storage capacity. IHA estimates that PSH projects now store at least 9,000 gigawatt hours (GWh) of electricity globally. Learn more.
The technology has proven to be an ideal solution to the growing list of challenges faced by grid operators over the past year. As the transition to a clean energy future rapidly unfolds, this flexible technology will become even more important for a reliable, affordable and low carbon grid.
