The Clyde power plant , called Clyde Power Station by the operator Contact Energy , is a run-of-river power plant in the Central Otago District of the Otago region on the South Island of New Zealand . The power station is fed by the Lake Dunstan reservoir .
geography
The Clyde Power Station is located below the Clyde Dam , just under 1 km northwest of the small town of Clyde and around 10 km northwest of Alexandra . The power plant can be accessed via Fruitgrowers Road from the west side of the Clutha River .
history
The power station was built together with the Clyde Dam , construction of which began in 1979. After 15 years of construction, in which numerous problems with the dam had to be solved and geological safety measures implemented, the power plant was able to produce electricity from hydropower for the first time on May 28, 1992. In the first tests, 73 MW were connected to the grid via a turbine. Since the reservoir had not yet reached its water level of 194.5 m above sea level at the time, the power plant could not yet be connected to the grid at full capacity. From the water level of 185 m, it was planned to go on the grid with 50 MW and to start with four turbines and 160 MW of power generation once its target value was reached. on October 22, 1992 the power plant reached its maximum output of 350 MW, which was later to be increased to the maximum output of 432 MW when the water level was sufficient.
Power plant data
The hydropower plant is supplied with water via four pressure pipes with a diameter of 7.8 m each. With a maximum flow rate of around 1000 m³ / sec, the power plant can produce a maximum of 432 MW of electricity via its four Francis turbines from Hitachi and the associated Hitachi Salient Pole Generators, each with a maximum output of 108 MW. The speed of rotation of the turbines, however, is 125 revolutions per minute.
The power plant generates a voltage of 220 kV via its generators and transformers, with which the electricity is fed into the country's national power network.
During the generation of electricity, the water level of the lake may fluctuate a maximum of one meter.
