A Natural Park, the mountain as a lifestyle and work opportunity, respect for nature, environmental sustainability, and the need for energy—these elements made it possible to create a collaboration between multiple parties (public and private) to support and launch the energy transition project of the association of refuge managers in the Écrins National Park in France.
With the project called “Refuges Zéro Fumée,” the first IREM hydroelectric turbine producing energy from a renewable source was installed at the Refuge de Chamoissière, run by Sebastien and Sylvie.
This solution allows the refuge to be almost completely decarbonized, significantly reducing the environmental impact of its management.


The energy needs of the Refuge de Chamoissière, located in the Hautes Alpes department (05) in the Écrins Natural Park in France, were met with the installation of an autonomous HYDRO POWER system, IREM model TPS.
This installation includes a Pelton IREM Ecowatt Hydro turbine with a generated electrical power of 5 kW, with manual flow regulation.


Sites like this, characterized by the complexity of the terrain and the need to optimize space, are suited to systems that are easy to manage and require limited maintenance. To regulate electrical parameters, the IREM Ecowatt Hydro system uses the constant load operating principle.
This system, in addition to having very short response times (1/150 of a second), ensures a high level of Power Quality for the loads served.
IREM’s design choices aim to maximize the robustness of the turbine-generator group and dump load regulators; materials and technical solutions create a product capable of operating in the most severe working conditions.
Finally, the guarantee of an industrially certified product tailored to the individual customer’s needs provides high quality standards while minimizing maintenance operations.
