Introduction
From underground caverns in Austria to record-speed builds in China and long-duration storage studies in the US, pumped storage hydropower is re-emerging as the backbone of renewable integration. A wave of projects in 2025 shows how engineers are adapting old principles to new. With higher needs for storage and grid support services, Pumped Hydro Storage is the natural large-scale energy storage solution. It provides all services from reactive power support to frequency control, synchronous or virtual inertia and black-start capabilities. It brings support that was. The Snowy 2.0 pumped storage project involves linking the existing Tantangara and Talbingo dams. (Credit: Snowy Hydro Limited) In February it was announced that Hitachi Energy has completed and handed over to Austrian power generator Verbund the world’s first static frequency converter (SFC). We bring cutting-edge expertise in all technical aspects of pumped storage — from early-stage studies to detailed engineering and project execution. Our multidisciplinary teams have mastered PSH configurations — closed-loop and open-loop systems, surface and underground plants — and work closely. NLR experts are developing tools and partnering with industry to unlock the full potential of pumped storage hydropower (PSH)—a form of hydropower used to generate electricity, store energy, and provide grid services.
