Summary

In this podcast episode, IEA analyst Yasmina Abdelilah discusses the often-overlooked role of hydropower in global electricity systems. She explains that hydropower is the third largest source of electricity generation, producing roughly as much as solar and wind combined, and is the largest source of low-carbon power. The episode covers the different types of hydropower (run-of-river, reservoir, and pumped storage), their benefits for flexibility and storage, and the geographical distribution of capacity, with mature markets in Europe and North America and rapid growth in emerging economies like China. Abdelilah highlights challenges such as aging fleets, high upfront costs, and regulatory barriers, and discusses policy solutions to support refurbishment and new development. The forecast suggests a 10% expansion by 2030, with potential for 15% more if barriers are overcome. The conversation emphasizes the need for hydropower to receive more policy attention and for mechanisms to value its multiple services.
