            Electrical Energy solution: Micro Hydro power plant

             

             

             

            Value proposition

            Main drivers 

            • Less than 30% of worldwide hydro resources are currently been used.
            • Global trend worldwide to invest in Renewable Energies
            • Hydro plants used as energy storage in some countries
            • Incentive from governments, for example the Renewable Energy Plan in Europe: 20% of electricity must come from renewable energies in 2020.
            • Ageing assets in some countries lead to massive renovation plans (example: RenouvEau plan in France)

             

            Solution in brief

            • Solution for micro hydro power plants, lower than 1MW: 1 turbine generator unit or several small generators (multi site) and local control.

            Main applications:
            • Turbine-Generator unit management.
            • Protection of generator set.
            • Synchronization to grid network.
            • HMI and remote monitoring.

            Customer benefits
            • Autonomous
            • Cost effective and compact solution
            • Ready-to-use, easy to integrate and set up
            • Remote management capability

            Differentiation factors
            • Complete solution from automation, electrical distribution to grid connection
            • Customer support in the design phase and along all the life cycle of the installation.
