    hydraulic

    With 15% of world electricity production, hydropower remains the most important renewable source of electricity. Between very small and very large hydro, of the “three gorges” type in China, this sector is made up of installations ranging from the run-of-river to the reservoir dam or to the pumped energy transfer station (STEP). Its deposits are still considerable in Africa, Asia and Latin America. The rehabilitation of old facilities wins in Europe.

    What do they have in common, between a small hydroelectric power plant built on a natural or artificial weir in a river, with a capacity of a few hundred kW, and the Three Gorges Dam power plant in China, with a capacity of 22,500 MW, the equivalent of five nuclear

    Hydroelectricity: environmental and societal impacts
    7 April 2021
    With a share of around 60% of the world’s renewable electricity production, hydropower is the leading renewable source of electricity. It is also considered as a clean energy insofar as its exploitation does not produce any waste. However, several projects have been, or still are, the subject of strong criticism.

    Hydropower : A vital asset in a power system with increased need for flexibility and firm capacity
    22 February 2016
    In a power system with increased need for flexibility, wind and solar power are characterised by considerable volatility across different scales and their output cannot be predicted with certainty. In order to deal with the resulting variations and forecast errors, system operators as well as electricity markets will need to

    Hydro turbines rehabilitation
    3 January 2016
    Except for specific cases, the rehabilitation of a hydro turbine generally concerns rather old machines for which most of the components have a strong potential of improvement. It is therefore usual to take advantage of the technology progress amassed from the time of the initial machine, to consider all the
