Hvammur, which is planned on the Thjorsa river in southern Iceland, about 120 km east of the capital Reykjavik, is the uppermost of three planned plants in the lower reach of the river. The initial design, which was updated between 2015 and 2017, foresaw the installation of two fish friendly 46.5 MW vertical shaft Kaplan units, each with a rated flow of 176 m3/s and a generator output of 57 MVA, which will operate under a gross head of 32 m. Landsvirkjun has since studied the feasibility of using one Francis turbine as an alternative to initial plans for two Kaplan units. The project is also designed to comprise a dam impounding a reservoir with a storage capacity of 13.2 x 106 m3 or 13.2 GL, a headrace tunnel with a length of 140 m and a width and height of 6.6-7 m, and two 191 m-long penstocks, with diameters of 6.8 m, and a tailrace canal with a length of 2000 m.
