On the 16th of February, Andrejsala's real property development company SIA Jaunrīgas attīstības uzņēmums entrusted to the collection of Latvenergo's Power Generation Museum the restored material belonging to the historical Andrejsala's power station's engineering blueprints, made by the then-renowned German engineer Oskar von Müller and his company in Munich.

The museum's task is thus to store 20 conserved documents that came into being in the time period between 1902 and 1928. The old drawings show Rīga's central electric power plant's details and functionality, such as water input and output, coal bunkers, underground transformers, electricity lines as well as lighting and fire-fighting equipment. The preservation work on the historical material is still ongoing, which will add several more graphical depictions of the apparatus to the museum's store of artefacts.

The Power Generation Museum's collection contains a variety of industrial heritage. This includes components, tools and even bigger machinery from the decommissioned Andrejsala's power plant: a 1935 steam boiler, made by the German company L&C Steinmüller, its control device (ca. 1968), a 1929 AEG steam turbine, British-made 6-kV power switches with bakelite insulation from the 1930s and 40s, USSR-made equipment for chemical treatment of water, as well as lathes, drilling machines and routers.

The power station's building is exemplary of the early stages of industrialisation of Rīga and an essential part of the local heritage. At the current state of the land use plans, it is envisioned to convert it into the emerging and multifunctional Latvian Museum of Contemporary Art.

Oskar von Müller began to lead the designing of the power station in 1901, and two years later the Rīga City Council approved the German engineer's construction plans and quotes. The building itself was drawn up by architect Kārlis Felsko. On the 14th of May 1905, Andrejsala's power station was first switched on. In 1987, the production of electricity stopped and the power station was converted into a heat generating plant, which continued to operate until the 31st of May 2004.

The preservation of the olden engineering documents is part of the Andrejsala history study, begun by SIA Jaunrīgas attīstības uzņēmums in 2007 with the aim of collecting and bringing up the vivid and varied, yet sometimes discreet surviving heritage in Andrejsala. The research project has collected a host of maps, photographs and written accounts, all of which reveal the history of the re-emerging part of central Rīga, the Andrejsala district.

More details on Andrejsala's power station and wider information on the area's history are included in our website's section History.
