Hvammur Power Station

Landsvirkjun is planning to build the Hvammur HEP, 95 MW hydroelectric project on river Þjórsá in the lower highlands of southern Iceland on the river Þjórsá approx. 100 km east of Reykjavík.

About Hvammur Power Station

Landsvirkjun has for years been conducting research and preparation work for the proposed Hvammur Power Station (Hvammsvirkjun). The power station will be located in Landsvirkjun's largest power production area, the Þjórsá and Tungnaá river region, where there are already seven power stations harnessing the energy of these two river systems. The source of energy production in the area lies in Hofsjökull and Vatnajökull, from which the water descends about 600 metres, releasing a tremendous amount of energy on its way to the sea.

The proposed power station will make use of the drop in the Þjórsá river below Búrfellsvirkjun, from the so-called Yrjasker, just above the farm Hagi, down past Ölmóðsey east of Þjórsárholt.

By harnessing the drop in the Þjórsá below the current power plants, 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.

High-quality design

In addition to assessment and planning work, the final preparations for the power station are currently underway, including careful architectural design of the structures, landscape design, a review of key aspects of the design, and implementation of mitigation measures to minimise environmental impact.

The power plant area, which is situated in a populated region, will be accessible and safe for pedestrians, who will be able to view power production structures in a relatively small area.

HVM10 Civil Works

HVM10 is the main civil works contract for the proposed 95 MW Hvammur Hydropower Project on the River Þjórsá in southern Iceland. The contract includes the construction of key project infrastructure, including earthfill dams, spillway structures, fishways, intake and water conveyance structures, the powerhouse, tunnels and associated works.

As the largest contract within the project, HVM10 forms the foundation for the development of one of Landsvirkjun’s major renewable energy projects.
