The Forstsee power plant is a hydropower plant in Techelsberg am Wörthersee that went into operation in 1925 as the first storage power plant in Carinthia .
The power house planned by Franz Baumgartner is located on the shores of Lake Wörthersee in Saag , a place in the Techelsberg community on Lake Wörthersee. The operator of the power plant is KELAG .
The power house houses a show power plant, in which the electricity generation is explained to the visitors . At the Forstsee itself, only a small dam wall reveals the use of its water to generate electricity. The height of fall to the power plant is around 160 m, the usable storage content of the forest lake is around 4.7 million m³, which corresponds to a generation of around 1.6 million kWh. The turbine output of the power plant is 2.4 MW. Electricity generation in a standard year amounts to 3 million kWh.
history
The idea for the construction of the Forstsee storage power station came from Adolf Wolf , chairman of the board of directors of the Klagenfurt municipal power station , in the early 1920s .
With this storage power plant, he wanted to eliminate the electricity bottleneck at the Klagenfurt electrical works in winter. And starting from this power plant, he wanted to connect the many local electricity companies with their small networks to form a common Central Carinthian network. These tasks should be carried out by a separate company. The weaknesses of the power supply in the individual communities became clear in the winter of 1921. Extremely low water put very tight limits on power generation and kept the grids collapsing; the state capital was particularly affected.
After the end of the monarchy in 1918, the energy supply in Carinthia had to be completely converted. No more coal was delivered from Silesia. Hydroelectric power seemed to be the viable alternative. The defensive struggle in Carinthia prevented a coordinated action by the public electricity industry until autumn 1920. It was not until 1922 that the Carinthian state power station presented a plan for the possible energetic use of local rivers and lakes.
On January 28, 1923, a founding committee launched the Kärntner Wasserkraftwerke-AG (KÄWAG) in Klagenfurt, with a share capital of 600 million crowns. They built the Forstsee power station and set up an electricity network in Central Carinthia. This company was renamed Kelag in 1939. Due to the 2nd Nationalization Act , the Kärntner Elektrizitätsaktiengesellschaft (Kelag) was created in 1948 through the merger of Kelag and the municipal power plants of Villach, St. Veit, Feldkirchen, Wolfsberg and Spittal.
The power house and outdoor facilities
The power station building is designed - according to plans by the "Wörthersee architect" Franz Baumgartner - outwardly and in details similar to a large villa, has been a listed building since 1995 and, as a power house, houses the turbine hall with generator and pump including an overhead crane with 8 t load capacity and separate ones Rooms for the power switchgear. A part of the machine hall separated by glass is freely accessible during the day and allows a view of the Pelton twin turbine via a staircase. Display boards explain the technology and history that the power plant is now completely controlled by the control center in Klagenfurt and was only used in pumping mode from 1928 to 1983 (summer). This role of energy storage has been taken over by larger pumped storage power plants from Kelag. Every year, Kelag has had the - since 1998: - show power station artistically used: the machines were strung with cords in 2008 and equipped with colored lights a different time, as the catalogs show. The large north wall inside shows the displacement of the bull and the shepherd by the machine in their red and black. The namesake of the electrical units of measurement written in brass in the terrazzo floor , such as Volta and Hertz, also remain permanent .
The summer daytime cafe Ampere has now been set up in the power plant building. On the terrace in a glass housing there is a turbine-generator combination similar to the initial equipment of the power plant, as well as a modern toilet facility. A small shipping pier with a few berths means that swimming is prohibited here.
A 110 kV substation was built west of the powerhouse in 1967, a local feed-in and power supply node. A 110 kV overhead line leads uphill over the motorway and forest lake to the north.
Refurbishment 2020/2021
From September 2020 to May 2021, the power plant is to be refurbished by 3 million euros and the pressure pipes also replaced. In order to assess the underwater facilities for the detailed planning, the intention was to dow the forest lake 15–20 m in October 2019, approximately to its natural height and damming it again in late autumn. The water level will also be lowered again for the construction work from October 2020.
Others
With the Hornburg power plant near Klein St. Paul , Baumgartner has planned another power plant in the style of a villa in Carinthia.
