Brúarvirkjun Hydro Plant

HS Orka is erecting a run-of-the-river hydropower plant in the upper stretch of Tungufljót river. Mannvit has been involved all the major preparations for the power plant, ranging from geological research to the EIA and mechanical design, project control and project management. This included all engineering design, geology, environmental reporting and research, Project Management, geotechnical engineering, preparation of tender documents, tendering, hydrological surveying and flow measurements. The Tungufljót river has its source above Haukadalur heath and flows into the Hvítá river near the farm of Bræðratunga.

The scope of Brúarvirkjun power plant is relatively small and the location is favourable in regards to visibility impact. The main dam lies across Tungufljót just above the confluence with the Stóra-Grjótá river. From there the river is channeled through a 1,700 m underground headrace tunnel to the powerhouse. Installed power is 9.9 MW and the hydropower plant can produce 82.5 GWh/year.



HS Orka is also working on projects locally to combat CO2 emissions through a forestry project in cooperation with government institutions Icelandic Forest Service and restoring wetlands in cooperation with Votlendissjódur wetlands fund. In the spring of 2018, over 25 thousand birch plants were planted in 10 hectares of land. The restoration of wetlands will be done by closing ditches in the Grimsnes community using material on the banks of the ditches.
