From water to wire, we’re adding value on new and refurbished hydro projects.

The first heightening of the Aswan Dam in Egypt began our 100+ years of involvement in hydropower, while our pumped-hydro storage heritage stretches back more than 60 years to the 360MW storage project at Ffestiniog, Wales, where we set a new paradigm in hydraulic design with the use of a unidirectional ternary unit and a buttress dam to reduce concrete use.

  • Over a century of experience since working on the first heightening of Aswan Dam in Egypt.
  • Scheme capacities ranging from 100kW to 7200MW.
  • Leading topography, hydrology, dam, tunnelling, water and storage expertise.

We help our clients harness the full potential of efficient hydro − one of the few forms of electricity generation with the flexibility to meet diverse operational requirements, enhance energy system security and stability and integrate with other renewables.

From feasibility and environmental impact studies and geotechnical and hydrological investigations to outline and detailed design, cost estimating and contract documentation, project management, construction supervision, commissioning and maintenance, we are with you from start to finish − and beyond, to future refurbishment and upgrade.

Our unique skillset covers every aspect of a hydropower or pumped storage project:

  • electro-mechanical
  • water resources
  • geological and geotechnical
  • dam, barrage and underground engineering
  • civil, structural and building services
  • environment, health and social
  • transmission and distribution
  • asset management

Key to our ability to successfully deliver hydro projects is the integration of our expertise across multiple disciplines, such as geotechnical investigations, dams, tunnels, powerhouses, electro- mechanical engineering, power transmission and distribution, and environmental and social. It enables us to combine strategic analysis with total technical capability, so we can begin adding value from the outset.
