The Rise of Pumped Storage and Modernization
Two forces are reshaping the global hydropower market: the growth of pumped storage hydropower (PSH) and the urgent need for modernization.
PSH acts as the world’s largest “rechargeable water battery.” It uses cheap, off-peak electricity to pump water to an upper reservoir and releases it to generate power during peak demand. PSH facilities store approximately 9,000 GWh of energy, over 90% of the world’s total energy storage. With 8.4 GW of new PSH capacity added in 2024 and 600 GW in the global pipeline, it is indispensable for balancing intermittent renewables.
Simultaneously, much of the existing hydropower fleet is aging. In North America and Europe, the average plant is 45-50 years old. By 2030, over 20% of the global fleet’s generating units will be older than 55 years, requiring major replacement. This presents a massive opportunity for modernization. Retrofitting older plants with new technology can boost efficiency, extend life, and improve environmental performance.
The required investment is significant: an estimated USD 127 billion is needed for modernization by 2030, with a total need of USD 300 billion to upgrade all aging plants. In North America and Europe, modernization will account for nearly 90% of hydropower investment this decade. Our modular construction methods at FDE Hydro™ make these retrofits faster and more affordable, helping to close the investment gap.
