A tunnel carries water from the dam to the hydroelectric power station at Sainte Lucie de Tallano in the Levo plain.
With installed capacity of 55 MW the power plant delivers almost 40% of the island's hydroelectricity.

Construction began in mid-2008.
The tunnel to carry water from the dam to the power station was completed on 15 October 2010.
On 21 May 2012 the dam was handed over to EDF to start filling the dam.
Impoundment of the Rizzanese reservoir began on 23 May 2012.
The first of two turbines was connected to the Corsican electricity network on 21 February 2013.
Full commissioning was expected in mid-September 2013.
