The EWL cooperative , until 2010 the Lauterbrunnen power station , is a cooperative based in the municipality of Lauterbrunnen . Members are around 600 cooperative members from the region with a cooperative capital of around 2.3 million Swiss francs.
The power supply of the community Lauterbrunnen belongs to the public law tasks. The entire in-house production is around 23 million kWh per year, of which around 650,000 kWh / year are generated from the Birrmättli drinking water power plant. The EWL employs around 60 people and trains 6 to 9 apprentices.
The company has the Lauterbrunnen, Mürren, Stechelberg and Wengen branches.
history
In 1894 the cooperative waterworks Lauterbrunnen fore was founded. Their intention was to create a hydrant network of 14 in the center of Lauterbrunnen. The cooperative was renamed the light and water works five years later. The purpose was expanded to include the passage “Generation and delivery of electrical energy for light and power purposes for the Lauterbrunnen community and the surrounding area”.
In 1905, the cooperative name Licht- und Wasserwerk Lauterbrunnen (LWL) was also entered in the commercial register. The old name "Lauterbrunnen waterworks foreground" was dropped.
On August 12, 1933 at 8:30 p.m., the Sefinental and the valley floor were hit by a violent thunderstorm with hailstorms. The EWL building and its facilities, the water intake and the pressure pipe were badly damaged.
The frequency of the network was increased from 40 Hz to 50 Hz in 1945/1946. This change was necessary because almost the entire Swiss distribution network was based on 50 Hz.
An extraordinary general assembly in 1955 approved the first energy supply contract with the Bernese power plants . A major innovation was that the EWL was able to sell practically all excess energy in the summer.
In 1974/1979 an all-round technical renovation took place: The inlet structure of the water catchment, the replacement and simultaneous enlargement of the pressure line, an increase in output of machine 2 to 2,700 kW and the construction of the switchgear as well as the semi-automation of the entire production plant were implemented. The valley-wide fiber optic network was put into operation in 2001. In 2005, the Birrmättli drinking water power plant went into operation. On March 31, 2010 the Lauterbrunnen electricity company changed its name to EWL Genossenschaft .
Power plants
Headquarters Stechelberg
The production center in Stechelberg has been in the back of the Lauterbrunnen valley since 1905. It is supplied with the water from the Sefinenlütschine through a 550 m long pressure pipe with a gradient of 252 m. The springs are located in the area of the UNESCO World Natural Heritage Jungfrau-Aletsch-Bietschhorn . The plant, which was modernized in 1979, contributes to the energy supply of the Lauterbrunnen Valley with its high-pressure drive ( Pelton turbine ) with a nominal output of 4,300 kW and an average annual production of a good 23 million kWh per year.
Birrmättli Lauterbrunnen drinking water power plant
The Birrmättli drinking water power station has stood above the village of Lauterbrunnen since 2005. The power plant is supplied by various drinking water sources from Spycherboden and Sieben-Brünnen through a 1113 m long pressure pipe. With the installed turbine output of 133 kW, the Birrmättli drinking water power plant supplies the EWL network with an average annual production of around 650,000 kWh.
Line network
The EWL cooperative builds, operates and maintains the electrical supply network (16 kV / 0.4 kV) as well as the public lighting in the Lauterbrunnen municipality and provides the necessary infrastructure. The EWL supply area covers the entire Lauterbrunnen valley. This includes the districts of Lauterbrunnen , Isenfluh , Mürren , Gimmelwald , Stechelberg and Wengen .
optical fiber
The fiber optic network of the EWL (cable and overhead lines), which was put into operation in 2001 , now covers approx. 30 km.
Dustbachfall lighting
The Staubbachfall , the landmark of the Lauterbrunnen valley, is illuminated by the EWL in the evening during the tourism season.
