Power plant group Fragant
The Fragant power plant group is a network of storage and run-of- river power plants in the Goldberg group , the Kreuzeck group and in the Mölltal . With an installed capacity of 474 MW, around 840 GWh of electricity are generated annually. The construction of the main parts lasted from 1963 to 1986. It was built by Kelag , which also operates it.
The coat of arms of the municipality of Flattach , decided in 2005 , to which the village and Tal Fragant belong, shows a Pelton turbine as a reference to the power plant group .
structure
The network consists of four storage and three run-of-river power plants:
Preliminary stages
The preliminary stages are passive storage power plants.
- Zirknitz power plant
The Zirknitz power plant is an annual storage power plant that uses the Großsee in the Zirknitz Valley and the Hochwurtenspeicher in the Fragant as storage . The Hochwurtenspeicher can be supplemented by the somewhat lower Weißsee , and this in turn by the Schwarzsee . The Großsee can be supplemented by the Zirmsee in Fleißtal via a gravity line. The underwater is channeled into the Wurtenalm reservoir via a gravity tunnel .
- Wölla power plant
The Wölla power plant is operated as a day storage facility. It uses the water from the Wölla operational storage facility, which pools the water from several streams in the northern Kreuzeck group. Its underwater is channeled into the Innerfragant intermediate storage facility on the other side of the Mölltal, from where it can either be pumped into the Oscheniksee via the Haselstein storage facility or fed to the Ausserfragant power plant.
Main stages
The main stages are pumped storage power plants .
- Feldsee power plant
The Feldsee power plant, which only went into operation in 2009, is a pumped storage power plant that connects the existing Wurtenalm storage facilities (below; pump reserve) and Feldsee (above; energy storage facility ). The latter originally served as a secondary storage facility for Lake Oschenik.
- Innerfragant power plant
The Innerfragant power plant is a pumped storage power plant that primarily uses water from Lake Oschenik . In addition, water from the relatively low Wurtenalm reservoir can also be used to generate electricity. The water from the Wurtenalm reservoir can also be used to feed Lake Oschenik. The underwater is either collected in the Innerfragant equalization basin or fed to the Ausserfragant power plant. In addition to the Wurtenalm reservoir, the Oscheniksee can also be supplemented by the Haselstein reservoir, which is located in the Innerfragant slightly above the Innerfragant intermediate reservoir, which in turn can be supplemented. In addition, excess water from the Haselstein storage facility can be processed to the Innerfragant intermediate storage facility .
Lower level
The lower level is the Ausserfragant power plant, which can use the underwater water of the Wölla and Innerfragant power plants or the stored water of the Innerfragant equalization basin. So it has a very small memory available and works with the power plants and Innerfragant Wölla with .
Run-of-river power plants
- Gößnitz power plant
The Gößnitz power plant is a run-of-river power plant on the Möll . It is not connected to the other power plants and was originally built to supply site electricity for the construction of the power plant group.
- Fleiß I run-of-river power plant
The Fleiß I run-of-river power plant was built by Tauernkraftwerke AG in 1947 , long before the other power plants, and was later taken over by Kelag. It uses the water of the Fleißbach stream.
- Fleiß II run-of-river power plant
The Fleiß II power plant lies above Fleiß I. The background was the diversion of the Fleißbach into the Wurtenalm reservoir, which is tied to the condition that the Fleißbach at Fleiß I must conduct at least 150 l / s. Since the quantities below the discharge are not always sufficient, water sometimes has to be let past the discharge into the Fleißtal. The Fleiß II power plant was built in 1971 to be able to use this water.
