About Ljosafoss Power Station

Ljosafoss Power Station is the oldest hydroelectric power station in the River Sog, and has been operating since 1937! This power plant first made it possible for homes in Reykjavik to stop relying on coal for cooking and heating their homes. It’s owned and operated by Landsvirkjun, the largest electric company in Iceland.

Iceland operates almost entirely on renewable energy sources, and Landvirkjun generates about 75% of the country’s electricity!
