Pumped storage hydropower and the case for resilient, autonomous, sovereign energy systems

Power systems are being asked to do more, more often, and under greater pressure. Recent global energy shocks have reinforced how quickly supply disruptions, fuel price volatility and geopolitical instability can flow through to electricity systems. In that context, resilience and energy sovereignty are no longer abstract policy objectives; they are becoming defining requirements of modern power systems. While pumped storage hydropower is technically proven and strongly aligned with future system needs, many projects are struggling to move beyond development – reflecting a broader misalignment between long-life infrastructure and current market and policy settings.

Drawing on industry discussions and engagement through the International Hydropower Association, Helen Barbour-Bourne, GHD’s National Sector Leader – Hydropower, explores why resilience, autonomy and energy sovereignty are now core system requirements, and what needs to change for pumped storage to play its full role.
