Sweco’s comprehensive expertise in energy-related services covers all stages of the energy supply chain – from production to distribution and consumption. The goal is to help our clients to develop a safe, cost-effective and environmentally sustainable energy supply. Sweco is a forerunner in finding innovative solutions that limit the use of fossil fuels. We also provide solutions that develop and enhance traditional types of energy facilities.

  • Process water for thermal and nuclear power plants
  • The use of biogas from sludge management of wastewater treatment plants
  • Wastewater treatment from power plants
  • Hydropower


The production of electrical energy from renewable resources has been continuously gaining on importance during the recent years. Hydropower is one of the main sources of such energy. Sweco Hydroprojekt is the author of a large number of projects pertaining to hydrotechnical and hydropower facilities for domestic and international clients. Some of these projects were prepared in cooperation with renowned international partners for whom we prepared or are currently preparing design documentation for large parts of hydropower facilities.

During the existence of Sweco Hydroprojekt, a total power generation capacity significantly exceeding 9000 MW has been designed and installed at large or smaller hydrotechnical facilities to the full satisfaction of the respective clients.

The following large projects in the area of hydropower engineering, completed during the previous decades should be mentioned:

  • Complete design and engineering services for the construction of the Vltava River cascade (700 MW of installed power generation capacity), including six concrete dams of various types, the largest one being over 100 m in height.
  • A significant part of the design and engineering services related to the Vah River cascade (500 MW of installed power generation capacity).
  • Complete hydraulic engineering design for the Temelin Nuclear Power Plant (the construction was divided into Phase 1 with power output of 2000 MW and Phase 2 with additional 2000 MW), including two dams on the Vltava River, a large pumping station and other equipment. Operation of this hydraulic system began in 1995.

At the present, our main focus is on small hydropower plants design and international assignments within the hydropower sector.
