About Elliðaárvirkjun
Elliðaárvirkjun is Reykjavík’s historic hydroelectric power station on the Elliðaár, playing a key role in supplying renewable electricity to the city since the early 20th century.
Visit Elliðaárvirkjun to see one of Reykjavík’s earliest renewable energy sites set within a scenic river valley known for walking paths and salmon fishing.
Elliðaárvirkjun is one of Reykjavík’s most historically important energy sites, located on the Elliðaár in Reykjavík. Built in 1921, the hydroelectric station marked a major milestone in the modernization of the capital by providing locally produced electricity during a period of rapid urban growth. At a time when reliable power was still limited in Iceland, Elliðaárvirkjun helped transform everyday life by supporting improved street lighting, homes, and emerging industries. The power station uses the natural flow of the Elliðaár river system to generate renewable electricity, reflecting Iceland’s early commitment to sustainable energy solutions. Although technology and energy production methods have evolved since its construction, the station remains part of Reykjavík’s electricity infrastructure today and stands as an important example of early hydropower development in the country. Elliðaárvirkjun is located within the scenic Elliðaárdalur valley, one of Reykjavík’s most popular outdoor recreation areas. The surrounding landscape includes walking paths, cycling routes, and well-known salmon fishing waters, making the site a unique place where industrial heritage and natural environments exist side by side. Visitors exploring the valley can observe how early engineering projects were carefully integrated into the landscape while continuing to support the city’s development. Today, Elliðaárvirkjun represents both a functioning renewable energy facility and a lasting symbol of Reykjavík’s transition into a modern urban centre powered by natural resources.
Folklore
Story & Folklore
At the beginning of the 20th century, as Reykjavík began to grow from a small town into a modern capital, the need for reliable electricity became increasingly important. The fast-flowing waters of the Elliðaár offered a natural solution. In 1921, Elliðaárvirkjun began producing electricity, becoming one of the city’s earliest renewable energy sources and an important step in Reykjavík’s modernization. The construction of the power station marked a turning point in everyday life for residents. Electricity improved lighting in homes and streets, supported new industries, and helped shape the development of the growing city. At the same time, the surrounding Elliðaár valley remained a natural green space, where people continued to fish for salmon and walk along the riverbanks. Today, Elliðaárvirkjun stands as both an active part of Reykjavík’s energy infrastructure and a reminder of how the city first harnessed its natural resources to support urban life. Visitors walking through the valley can still experience this unique meeting point between nature, history, and early renewable energy innovation.
