The HydroFlex project uses five hydropower plants as reference sites for the research and innovation activities in the different work packages.

Porjus

Porjus hydropower plant, which is operated by Vattenfall, is located on the Stora Luleälv river in the municipality of Jokkmokk, Sweden. It is Sweden’s third largest hydropower plant. Porjus is equipped with Francis turbines with a total capacity of 465 MW.

The Porjus Hydropower Center is a large scale test facility consisting of two turbine-generator sets (U8 and U9) with a capacity of around 10 MW each.

Bratsberg

Bratsberg hydropower plant, which is operated by Statkraft, is located on the Nid River in the municipality of Trondheim in Trøndelag County, Norway. It is equipped with two Francis turbines with a total installed capacity of 124 MW. The average annual production is 650 GWh.

Bratsberg power plant is one of six power stations on the Nid River. Water is drawn directly from Lake Selbusjøen and transported in a 16-kilometre-long diversion tunnel through the power station to the outlet below Nedre Leirfoss. The height of fall of 147 metres is the sum of all the waterfalls and rapids in the Nid River.

Kvilldal

Kvilldal hydropower plant, which is operated by Statkraft, is located in the municipality of Suldal in Rogaland, Norway. Kvilldal is part of the Ulla-Førre hydropower complex, which is Northern Europe’s largest and includes the artificial lake Blåsjø, which is made by dams around 1,000 meters above sea level.

The Kvilldal facility operates at an installed capacity of 1,240 MW, making it the largest power station in Norway in terms of capacity. It is equipped with four Francis turbines.

Stornorrfors

Stornorrfors hydropower plant, which is operated by Vattenfall, is located by the Ume Älv River in Västerbotten County, Northern Sweden. It is Sweden’s second largest hydropower plant and generates the most electricity of all hydropower plant in Sweden. It is equipped with four Francis turbines with a total capacity of 599 MW.

Stornorrfors has one of Europe’s longest fish ladders (300 metres long) and it has been a site for many studies of fish migration including both numerical and experimental investigations.

Lysebotn2

Lysebotn 2 is Lyse’s brand new hydropower plant. Commissioning was completed during spring 2018. It is located in Lysebotn in Rogaland, Norway. Lysebotn 2 is replacing Lysebotn 1 powerplant, using the same water, but increasing the energy output.

Lysebotn 2 has an installed capacity of 370 MW and is equipped with two Francis turbines. The power plant can utilize water from two different reservoirs, named Lyngsvatn and Strandvatn. The hydropower plant is built especially to meet demands of coming markets.
