Power plant Langweid

This second power station on the Lech canal was built in a similarly elaborate design as the plant in Gersthofen. It has been producing electricity since 1907, initially for a factory, then for the general supply. Today, it is home to the Lechmuseum Bayern, which features the river as well as impressive technical installations.

Building history and description
  • Hydroelectric power plant, still in operation today
  • community Langweid, Landkreis Augsburg; Lechwerkstraße 19
  • Start of sewer excavation 1898
  • Commissioning 1907
  • two-story superstructure of the empty shot 1938
  • first replacement of three turbines in 1957
  • second exchange of three turbines and all generators in 1993
  • Opening of the Lechmuseum Langweid 2008
  • Castle-like brick building in the style of historicism (strongly based on the power plant in Gersthofen)
  • elongated, two-storey solid construction with single-storey side wings
  • Facade in exposed brickwork with pilasters and white decorative elements
  • Round arched windows with steel rungs
  • longitudinal building with flat roof
  • three-storey buildings to the east and west with hipped roofs covered in beaver tail
  • self-supporting machine hall with 10.5m height and 13m width with filigree riveted steel truss girders and crane runway in 8m height

Use and purpose
  • Hydropower plant for power generation (first for company, then for region)
  • Switchgear in overbuilding of the lock (unknown year)
  • Administration and former control room in the west wing (control from the power plant in Gersthofen today)
  • Technical Equipment
    • One 1907 Francis turbine
    • One 1907 Siemens-Schuckert-generator
    • One Kaplan turbine with vertical wave from Voith
    • One 1938 Siemens-Schuckert bell-ring generator
    • three AEG generators from Escher Wyss
    • three Kaplan turbines from Escher Wyss
  • Power station on the Lech Canal built in three sections from 1898-1922
  • Foundation of the Lechwerke 1903
  • Lech Canal was extended by 2.5 km to Langweid until 1906
  • Power plant as an object of the UNESCO nomination stands for:
    • Further development from small-scale to industrial scale
    • Further development from a simple waterwheel to a highly effective turbine
    • early replacement of mechanical transfers of hydroelectric power in the region by electrification
    • Early replacement of local hydropower and electricity generation by decentralized run-of-river power plants
    • Use of renewable energies benefits the environment,
    • "Augsburg tradition" of sustainability as a global role model
Authenticity and unique features
  • Construction-time turbine as a showpiece (good traceability of the functioning of a turbine and the water supply), coupled to construction-time generator
  • Turbine and generator from 1938 also preserved (still in operation today)
  • Modernization of the three middle machine sets in 1993
  • Use as a Lechmuseum
  • technical equipment as a cross-section of the hydropower plant technology of the entire last century
  • Providing technical development to a well-preserved, exemplary hydropower plant
