The three power stations on the river Sog are among the oldest in Iceland. Sog was harnessed to provide electricity for Reykjavik, which until then had only been supplied by the Ellidaar station on the outskirts of the city. In its day the Sog development was a huge project and caused some controversy, largely about its cost and financing. The station on Ljosifoss, the first fall to be harnessed, was constructed in the second half of the 1930s and went on stream in 1937. Irafoss Station was added later, followed by Steingrimsstod. An average of 20 employees work at the Sog Stations.
