Pumped-storage hydro: purpose-built and made to last
Pumped-storage hydroelectricity (PSH) is gaining momentum globally as a large-scale energy storage system for a sustainable future. Its ability to provide extensive, long-duration energy storage makes it essential for integrating renewables and maintaining grid stability.
Innovative, sustainable engineering for a renewable future
We use innovative techniques to enhance efficiency, sustainability and adaptability in PSH systems. Our teams repurpose brownfield assets, such as abandoned quarries, for reservoir development, supporting environmental remediation while reducing construction costs.
We also incorporate advanced technologies such as variable speed units and hydraulic short circuits to improve plant responsiveness to market demands. For added versatility, we integrate onsite batteries or generators for specific system services such as black start capabilities. By using on-site materials for construction, we reduce environmental impact and construction costs.
Full lifecycle delivery, backed by global experience
With decades of experience delivering large-scale civil infrastructure — including hydrochemical works, tunnels and dams — we manage the full complexity of pumped-storage hydro projects. Our integrated services span the entire project lifecycle, from siting and permitting to design and construction.
Backed by global experience on some of the world’s most advanced hydropower initiatives, we tailor each solution to meet regional needs and deliver long-term performance.
