The Central Kraftwerke AG (CKW), formerly electrical utility Rathausen AG , based in Lucerne is a producer holder and distributor of electricity in Switzerland . The company, organized under private law, was founded in 1894 with its headquarters in Rathausen . Axpo Holding AG holds 81% of the shares in the company , the canton of Lucerne has a 9.9% stake, the remaining 9 percent are in free float .
history
CKW emerged from the Rathausen power station . The operating company Elektrizitätswerk Rathausen AG ran into financial difficulties in 1909 and had to be restructured. The task was taken over by Fritz Ringwald , the new director. In the same year, the company took a stake in the Altdorf power station and financed the construction of the Arniberg power station near Amsteg . In 1913, the Schwyz power station was bought and in the same year the name of the company was changed from Elektrizitätswerk Rathausen AG to Centralschweizerische Kraftwerke AG (CKW) .
Further municipal works and holdings in other power plants were taken over. The entire power grid of the canton of Lucerne was set up from Rathausen. The first large transmission line was built between Rathausen and Gösgen in 1924 . The eleven most important plants in German-speaking Switzerland were linked directly or indirectly via the switching and transformer stations in Gösgen and Rathausen.
The CKW propagated the use of electricity in the kitchen and in agriculture, where the supply network should also reach remote mountain areas. For the farmers, hay ventilation and artificial lighting in chicken coops were thought of. To meet the increasing energy demand, CKW had the Lungernsee power plant built, which was built in stages from 1921 to 1933. Further power plants followed in partnership with other electricity suppliers. This included the plants in Wassen , Calancasca , Mauvoisin , Göschenen , Isenthal and Alpnach . The Urseren power plant project pursued by CKW could not be implemented despite two attempts due to strong resistance from the population. As a replacement for the system, the Göschenen power plant was expanded to include the Göscheneralpsee .
With the establishment of the Mettlen substation in Inwil , Rathausen was connected to the Swiss network. The Lukmanier line , a three-pole 380 kV three-phase high-voltage line from Lavorgo over the Lukmanier Pass to Mettlen, was built in 1949.
