Energy & Water

We are specialized in all aspects of hydropower engineering. Our expertise covers of generation schemes, from high head to run-of-river, as well as pumped storage facilities. We cover the entire project lifecycle, from conception and design to commissioning, operation, and maintenance. This includes social and environmental impact assessments, civil and electromechanical design, as well as project appraisals and due diligence. We are currently engaged in significant pumped storage projects worldwide, supporting the transition to renewable energy sources.

Leveraging our core competences in both civil and electromechanical engineering, we offer comprehensive solutions for project planning, design and construction supervision services for both surface and underground powerhouses. Our extensive experience also covers expansion and rehabilitation solutions for existing powerhouses.

Hydraulic and underground structures have been at the core of our business since the foundation of Lombardi. Thanks to our experience on many projects in Switzerland and around the world, we gained a deep understanding of the unique challenges related to the design, construction, operation and maintenance of hydraulic tunnels and shafts in a wide range of conditions. Our experience cover design of high pressure and low pressure system, including mechanized (TBM) and drill and blast tunnelling.

We have extensive experience in designing steel penstocks and linings for both generation and pumped storage hydropower plants. We also have experience with FRP penstock, offering a flexible alternative for lower pressure applications. We also offer comprehensive assessment of existing penstock, including evaluation and retrofitting of existing structures.

Our hydromechanical team of engineers is involved since the early design stage of hydropower plants, ensuring a complete and multi-disciplinary approach. We can help our clients select the optimal solutions for their project and accompany them during the entire procurement process up to commissioning. We are also experienced in the assessment of existing generating and pumping units, gates and valves, providing comprehensive solutions for refurbishments and upgrades.

With our Electromechanical equipment team we can offer complete design services for the Water to Wire equipment of a powerhouse including the evaluation of the entire range of hydraulic turbines such as Francis, Pelton, Kaplan, etc. we also can provide specific assistance on the definition of pump-turbine based on his long experience on pumped storage schemes.

We have dedicated teams assisting in providing the required design and specifications definition for the electrical and mechanical balance of plant of a hydropower schemes. In addition we are specialized in HVAC systems for underground structures (caverns and tunnels).

From the monumental Contra arch dam completed in 1965, one of the world's tallest and most slender, to the innovative RCC gravity arch dam of Arenal finished in 2021, dam engineering has always been at the core of our expertise.

Our comprehensive services cover the entire spectrum of dam engineering, including design from inception to completion, safety evaluations, rehabilitation strategies, and full-scale surveillance and monitoring solutions. In our team includes several federal dam safety experts appointed by the Swiss Federal Office of Energy.

Our competences include water transfer systems and pumping stations, crucial components in effective water resource management. With our involvement in major water supply projects, such as the ongoing Upper Wawa pumping station project, delivering potable water to the citizens of Manila in the Philippines, we understand the critical role these systems play in ensuring access to clean and reliable water. We offer end-to-end solutions, from design to construction and commissioning supervision.

During that past years we were able to consolidate our expertise in different types of renewable project other than hydropower. In Switzerland we were able to contribute to important flagship solar projects such as the largest solar park at Muttsee dam and the on-going Lac des Toules solar floating project.

We continue to position ourselves in urban drainage and flood protection system providing widespread services with a multidisciplinary approach. The recent contribution to the detailed design of the drainage system of the city of Trujillo in Peru consolidated our position in this field.

We offer comprehensive river engineering services, including flood management measures, as well as re-naturing projects aimed at restoring natural river functions and habitats. We have extensive experience in 1D and 2D numerical modeling, ensuring accurate assessments and effective solutions for river systems.

We provide comprehensive services for designing and optimizing irrigation schemes, ensuring efficient water distribution and sustainable agricultural practices.

Specializing in hydrological studies and numerical watershed modeling, we provide comprehensive assessments of water resources and conduct safety evaluations for dam spillway capacities.
