    Dams and hydroelectric power plants

    We offer comprehensive services covering everything from design and construction supervision to operations and maintenance. Our extensive work in this area is testament to our commitment to clean energy.


Designing safe dams and hydroelectric power plants

At Ayesa, we offer services covering theentire life cycle of dams. This sees us participate in their design, supervise their construction, analyse their behaviour, and provide support to their owners for operations, maintenance, inspections and repairs. In fact, our teams have been involved in many of the more than 1200 large dams throughout Spain. What’s more, we detect pathologies and assess safety as well as draft and check all safety documentation and compliance with applicable laws and regulations. We also follow Spain’s Technical Regulations for Dam Safety, which are designed to ensure their entire life cycle is correctly managed, from design, control and monitoring through to decommissioning.

Types of hydroelectric schemes in place include large hydro schemes that use dams to impound water in a reservoir, creating a large head of water, and pumped storage for large-scale energy storage. Based on our firm belief that renewable energy will soon surpass fossil fuels, and in line with Horizon 2030 and Horizon 2050, we have taken part in major hydropower projects in Spain and around the world.

Our expertise and technology

We have the knowledge, experience and tools necessary to successfully design any kind of dam and hydropower facility in accordance with all applicable laws and regulations.
BIM projects
The experience we have acquired through major projects involving hydroelectric power plants and our expertise in BIM give us a competitive advantage when tackling complex work in all the areas involved, including civil engineering, mechanical engineering, electrical engineering, instrumentation and control engineering, and PID control.
Powerful calculation tools
Our expert teams use specific calculation software to resolve complex problems that arise over the course of our projects. These include FEM (Slide by Rocscience, PLAXIS 2D and 3D, and midas GTS NX) and computational fluid dynamics (Ansys Fluent and Flow-3D).
A diverse team of specialists and partners
Over the decades, our experts have provided a wide range of services as part of projects in Spain and around the globe. Many of the individuals and firms we work with on a regular basis are recognised by the industry worldwide.
All-in-one solutions for projects
At Ayesa, we have the structure and expertise as well as the resources necessary to handle all aspects involved in dam and hydroelectric power plant projects, regardless of their complexity and size.
Experts in local laws and regulations
We have extensive knowledge on the laws and regulations governing dams in Spain and around the world. This, combined with our experience applying these as part of hundreds of projects, means we are able to offer services that are synonymous with excellence and inspire trust.


These structures have become a key part of human development and well-being. Despite their size, which is often colossal, designing them requires even the smallest of details to be carefully thought out, something that only a truly experienced team can achieve. This is because any mistake made during the concept generation, design or construction phases, or relating to control and safety monitoring, may be critical and result in a disaster of enormous proportions. As a society, we are increasingly aware of the extreme importance of this type of infrastructure and are therefore more demanding in terms of what we expect from it.

At Ayesa, we are conscious of this fact, which is why for the past 50 years, we have been been offering our clients unbeatable services throughout the life cycle of their dams, from design, construction and filling to operations, maintenance, safety monitoring and decommissioning. Our projects in this area have unfailingly been a resounding success, and our mission continues to be to offer the highest levels of safety and reliability.

Hydroelectric power plants

One of the big achievements of humanity has undoubtedly been the development of hydropower, something which sees us harness the energy of water through large-scale hydro schemes and pumped storage solutions. Hydropower continues to play a key role in the energy mix, and is set to become even more important within the current context of the renewable energy transition and the expansion of renewable energy. Its enormous versatility, flexibility and, above all, ability to be stored, has seen hydropower become particularly popular.

At Ayesa, we participate in major projects in South America and Spain, and have become a go-to partner for our clients in the industry. We have a multidisciplinary technical team and an impressive portfolio of experience in the technology used at hydroelectric power facilities.
