Olidan Hydroelectric Power Station

Olidan Power Station (Swedish: Olidans kraftverk) is a hydroelectric power station located in Trollhättan, Sweden.

First opened in 1910, it was the first large scale attempt at generating electricity from water in Sweden.

The construction of Olidan led to the founding of the Kungliga Vattenfallsstyrelsen (Royal Waterfall Board), which later became Vattenfall.

Due to increasing demand, as well as increasing capacity due to the regulation of Göta älv, another five were then built.

When Olidan were completed in 1924, planning began for Hojum Power Station, which came into service in 1938.
