The hydroelectric power plant Kardaun , also called hydroelectric power plant Carlo Cicogna , is a run-of-river power plant in Bolzano in South Tyrol , which is fed by the hydropower of the Eisack . Cardoon is the largest power plant in South Tyrol.
location
The power plant is located in the municipality of Bolzano in the Leitach- Wangg district, about 4 km east of the city center near Kardaun , a fraction of the municipality of Karneid . The power house, water tunnel and castle and weirs are located on the right bank of the Eisack, not far from the Brenner motorway . The water intake is further north in the Kollmann district of the Barbian community .
From there the water flows through a 14.8 km long tunnel to the moated castle above the power station.
history
The Munich company Sager & Woerner produced designs for the plant as early as 1911, while still under the Austro-Hungarian Empire . Due to the war, Kraftwerk Hochetsch AG only received the concession for the construction of an electrical works in Kardaun on April 29, 1922 - already under Italian administration. The Eisack water should be drained off in Waidbruck . The execution was under the direction of Gaetano Ganassini. The building was named by the fascist regime after the engineer Carlo Cicogna Mozzoni, chairman of the Azienda elettrica municipale di Milano and the Società Elettrica del Valdarno . When it was commissioned in 1929 by the Societa Idroelettrica dell'Isarco (SIDI), it was the power plant with the highest output in Europe and equipped with the most modern technology at the time.
From 2011 the power plant was managed by SE Hydropower , a consortium of Enel and Sel. The successor group to Sel, Alperia , has been the sole owner since 2016 .
By 1965, 3 more Pelton turbines generated electricity for the Brenner Railway and were driven by a 6th pressure line. Pelton turbines and the associated pressure line were dismantled after 1965.
technology
The height of fall from the water tower is 165 m. The total output of the power plant (121 MW) results from the max. Individual power of the turbines (33 MW), but only 4 of them produce at the same time. The max. The flow rate is 90 m 3 / s.
The floor plan of the engine room measures 100 m × 16 m.
