Pont du Grand Clapey power station

CLIENT: Meyes S.r.l.
POWER: kVA 245
YEAR: 2003/2004

The “Pont du Grand Clapey” power station is situated in the village of the same name in the municipality of Valsavarenche. External construction companies built the civil works, penstock and tanks, then Fratelli Ronc completed the power station.


Like the one in Pont, the station lies on the main axis of the Grand Paradis aqueduct, where the hydraulic situation demanded the inclusion of pressure break tanks. The hydraulic power produced is transformed into electrical energy. Production is assured by an asynchronous generator and a Pelton wheel, with a power of approximately 220 kW.


The plant operation is automated, is not manned, and information relating to the station’s electrical and mechanical parameters is sent to the Introd supervision centre. As far as the intake structure is concerned, in contrast to traditional power stations using running water, turbined water accumulates in conventional break tanks and is transported to the power station downstream through the pipes of the existing water supply.


Like the one in Pont, this plant was based on the model adopted by F.lli Ronc for the municipal aqueduct in Grand Combin.
