Dams & Hydropower

Engineering water-based solutions for clean, dispatchable energy

Large-scale generation, grid flexibility, and long-term energy storage through robust, efficient and environmentally integrated infrastructure

Dams and hydropower continue to play a key role in global decarbonization and energy security. As one of the most mature and reliable renewable energy sources, hydropower enables large-scale generation, grid flexibility, and long-term energy storage. At Sener, we offer comprehensive engineering and project management services for hydroelectric plants, dams and pumped storage systems, helping our clients unlock the full potential of water resources through robust, efficient and environmentally integrated infrastructure.

We deliver resilient hydropower solutions adapted to terrain, hydrology and sustainability goals

Our projects are designed to maximize energy output while minimizing environmental impact, integrating sediment control, fish migration and water resource management in every phase.

Why choose us

We combine hydrological, geotechnical and structural engineering to deliver tailor-made solutions for both new and existing assets. Our expertise covers gravity and arch dams, penstocks, spillways and all associated electromechanical systems. We also provide advisory and technical assistance for retrofitting and repowering plants to meet modern efficiency and environmental standards. In parallel, we apply advanced modeling and predictive maintenance strategies to optimize performance and extend asset lifespan.

How we work

We address hydropower infrastructure as complex, multidisciplinary systems. Our teams manage everything from preliminary studies and environmental permitting to detail design, construction supervision and O&M planning. We work in close coordination with local authorities, utility companies and financial institutions, ensuring alignment with technical, regulatory and funding requirements.

We create and manage hydropower projects from concept to commissioning

Whether for run-of-river plants, reservoirs or reversible pumped storage, our work ensures safe operation, efficient energy generation and long-term resilience to hydrological variability.

Our integrated solutions for dams and hydropower

We deliver comprehensive expertise in dams and hydropower, covering civil and hydraulic engineering, hydropower systems, and advanced modelling. Services include pumped storage, asset modernisation, and environmental integration. With strong capabilities in monitoring tools, permitting, and project management, we ensure efficient, sustainable, and reliable energy infrastructure across the entire hydropower lifecycle.
