The Canutillar power plant ( Spanish Central [hidroeléctrica] Canutillar ) is a hydroelectric power plant on the Reloncaví Fjord in Chile . The power plant is located in Region X , approximately 50 km east of the city of Puerto Montt . The Calbuco volcano, which erupted in April 2015, is located approx. 30 km northwest of the power plant.
The Canutillar power plant went into operation in 1990. It is owned and operated by Colbún SA .
Chapo lake
Lake Chapo , 240 m above sea level , serves as a storage basin for the power plant, which uses the difference in altitude between the lake and the Reloncaví Fjord . The volume that can be used to generate electricity is 900 million m³. The water level of the lake can fluctuate between 241 and 221 m. The water level reached a minimum of 223 m in 2013, which led to criticism of the power plant operator Colbún from residents and environmentalists.
At the south-eastern end of the lake is the inlet , from which the water is led through a concrete-lined tunnel (length 6.7 km, diameter 4.5 m) to the fall zone. The moated castle is located there (height 71 m, diameter 8 m). Then the water is first passed through a vertical pressure pipe (length 90.5 m, diameter 3.90 m). This is followed by a tunnel with a 15% gradient (length 212 m, diameter 3.90 m), which finally divides into two tunnels (length 115 m, diameter 2.75 m) that lead to the power plant's turbines.
power plant
The Canutillar power plant has an installed capacity of 172 MW . The average annual production fluctuates: in 2008 it was 799 million kWh and in 2007 it was 1.138 billion kWh.
The two machines of the power plant were put into operation in 1990. The Francis turbines have a maximum output of 86 MW each. The data of the originally planned machines were: output 64.2 MW and nominal speed 375 / min; Nominal voltage of the generators 13.8 kV . In the switchgear , the generator voltage of 13.8 kV is increased to 154 kV by means of power transformers. A 60 km long double line leads from the switchgear to the Puerto Montt substation .
The average height of fall is 232.4 m, the maximum 237.4 m. The maximum flow rate is 32.5 m³ / s per turbine.
owner
Canutillar was built by the Empresa Nacional de Electricidad SA Chile (ENDESA). In 2003, ENDESA sold the power plant to Minera Valparaíso , a subsidiary of the Chilean Grupo Matte, for USD 174 million . In 2005, Colbún SA merged with the power plant business of Grupo Matte , whereby the Canutillar power plant became the property of Colbún.
Others
The total cost of the entire project was $ 262 million, with the power plant itself accounting for $ 168 million. With an assumed service life of the power plant of 50 years, the costs per kWh were calculated at 2.7 to 3.2 US cents.
