Øvre r ø ssamatga电厂

Øvre r ø ssamatga电厂 uses the height of fall between Lake Røssvatnet and Lake Stormyrbassenget, while Nedre Røssåga power plant uses the height of fall between Lake Stormyrbassenget and the village of Korgen.

Lake Røssvatnet has a reservoir capacity of 2.35 billion cubic metres, and is 挪威's second-largest lake measured by surface area.

The development of the Røssåga power plants involves the municipalities of Hemnes, 哈特杰达尔和格兰. The development was linked to operating the ironworks in Mo i Rana and the aluminium plant in Mosjøen.

Øvre r ø ssamatga电厂 has three generating units with Francis turbines. The gross height of fall is 136 metres.

在2016-2018年期间, the three generating units at Øvre Røssåga were rehabilitated and a new parallel outlet tunnel put into operation. 增加力量, new tunnels and rehabilitation projects raised production levels by 200 GWh at Øvre and Nedre Røssåga power plants.

Architect Hans Grinde drew the plans for and participated in the planning of Øvre r ø ssamatga电厂.
