France, St. Christophe, Reallon, Charmaix

In December 2015, ANDRITZ HYDRO successfully commissioned two Mini Compact hydropower plants in France: HPP Saint Christophe and HPP Real­lon.

Both hydropower plants are loca­ted in the French Alps and are owned by SERHY Ingénierie, a company very active in hydropower development.


The Saint Christophe hydropower plant required rehabilitation of one existing unit and the installation of an additional horizontal Pelton turbine. HPP Reallon, equipped with a six-jet Pelton turbine, was a new plant with integration constraints since it is located in the middle of a village. Both projects were realized simultaneously and put into operation in less than one year. ANDRITZ HYDRO provided turbines, generators, inlet valves, and a high pressure unit (HPU).

The long-term and successful cooperation between SERHY Ingénierie and ANDRITZ HYDRO will also continue in 2016. A new Mini Compact contract for the supply of a five-jet, vertical Pelton turbine for HPP Charmaix was signed at the beginning of the year 2016.

Commissioning of all projects is sche­duled for the end of the same year.
