Maroggia hydropower plant exploits water contributions of Maroggia river tributaries by means of three intake works in Valle Laresa, Val di Mezzo and Val Vignone, in the municipalities of Berbenno and Buglio in Monte (Sondrio province).
The derived flow rates are conveyed by a pipe which connects the three intakes to a forebay, built immediately downstream of Val Vignone intake.
The steel penstock, about 2.7 km long, starts from the forebay and conveys the flow rates up to the powerhouse located upstream of Ere and Ronco residential areas.
The building of the powerhouse feeds a two-jet Pelton turbine directly coupled to a synchronous generator.
Finally, water is returned to the Maroggia river through a short tailrace channel.
The plant went into operation at the end of 1998. Find out Frosio Next’s contribution to the realization of the plant!
