  • Hydroelectric Power Stations and Fish Migration

    Hydroelectric power stations in rivers produce potential injury to downstream migrating fish as they pass through the turbines. Highest mortality rates are found for eel and ranges between 15 and 38%. The impact of fish passage through a series of hydroelectric power stations in one river can be very high. This might be the case for river systems like the river Rhine or Meuse where many ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Evaluation of melioration area damage on the river Danube caused by the hydroelectric power plant ‘Djerdap 1’ backwater

    Construction of the hydroelectric power plant (HPP) ‘Djerdap 1’ formed a backwater effect on the Danube and its tributaries, which had an inevitable influence on groundwater level, causing it to rise and thus creating additional threats to all melioration areas on more than 300 km of the Danube riversides, as well as on the riversides of its tributaries: the Sava (100 km) and the ...

  • Continuous Quality Surveillance Scheme to minimize the Cost Of Poor Quality in the construction of hydroelectric powerplants - IDRA 2012

    During the construction of hydroelectric plants, poor quality can have a hugely negative impact on construction time, on plant performance and on safety. We propose a method of keeping under control the manufacturing of the most critical components, such as pressure parts, rotors and valves, with a view to minimizing the Cost of Poor Quality (COPQ). This method is known as the Continuous Quality ...
