Construction Projects
Landsvirkjun is continuously working to advance new energy projects to strengthen Iceland’s renewable energy system and support the energy transition.
The picture above shows work on turbine foundations at the Vaðalda Wind Farm at sunset in autumn 2025.
Iceland's very first wind farm
Vaðalda Wind Farm will be located in Landsvirkjun’s largest area of operation. It is the first wind farm in Iceland and will comprise 28 wind turbines across a 17-square-kilometre site, with the first blades expected to start turning by the end of 2026.
The wind farm creates an opportunity to harness the combined strengths of hydropower and wind energy in the region, maximising the potential of the renewable resources entrusted to Landsvirkjun.
Expanding Geothermal Opportunities at Þeistareykir
Three major projects are shaping the future of Þeistareykir: the expansion of Þeistareykir Geothermal Station, the installation of a topping unit and the development of a geothermal innovation site.
Together, they will increase renewable energy generation, improve resource utilisation and create new opportunities for innovation and value creation.
Harnessing the power of river Þjórsá
Landsvirkjun has for years been conducting research and preparation work for the proposed Hvammur Hydropwer Station (Hvammsvirkjun). By harnessing the drop in river Þjórsá below the current power stations, Landsvirkjun seeks to maximise the utilisation of the energy resources entrusted to the company.
The Hvammur Power Station’s installed capacity will be 95 MW, and the annual energy generation will be approximately 740 GWh.
Expanding capacity at Sigalda Power Station
The expansion of Sigalda Power Station involves an extension to the southwest of the existing powerhouse, including a fourth generating unit and a new penstock. In addition, the tailrace canal near the station will be widened.
Once completed, the installed capacity of Sigalda Power Station will increase from 150 MW to 215 MW.
