PD&MS works closely with hydropower developers and operators to streamline and enhance hydropower plants.

From initial feasibility studies, through design studies to detailed project planning, we have the knowledge and experience to support the delivery of innovative, practical and cost-effective hydropower solutions. The scope of our work ranges right across the life cycle of hydropower plants and can include support with site investigation and selection, equipment procurement, and design and construction. It also covers all sizes of hydroelectric and pumped storage schemes, from mini hydroelectric projects of less than 100kW capacity, to major multi-GW projects. Our hydropower plant services include:
