Pumped Hydro Energy Storage

01 02

Using the power of gravity to generate energy

Pumped hydro energy storage uses the force of gravity to generate electricity, absorbing surplus energy at times of low demand and preparing it for release when most needed.  

Our team of specialists know how clean energy storage works, and we can help find storage solutions to keep your most precious resource ready for when you need it.

A world leader in pumped storage planning, we’ve worked since the 1960s on over 150 projects, providing tens of thousands of megawatts across the world. We have successfully delivered feasibility studies as well as concept and detailed designs for challenging, complex multidisciplinary projects situated in environmentally complex conditions in New Zealand and globally.

We’re committed to partnering with you to achieve your sustainability goals by delivering inventive solutions to solve complex challenges.
