Bardu hydropower plant

The Bardu HEP refers to two hydroelectric projects (HEP) in the municipality of Bardu in Troms County in Norway. The projects harness the discharge from the rivers Dittielva and Krogstadelva which are both tributaries to the Bardu river (n. Barduelva), the largest source of hydroelectricity in Troms county.

The Hydroelectric Projects are located in the municipality of Bardu in North-Norway at 68°N. The installed power is in total 9,9 MW in two separate powerstations.

The dams are vertical concrete walls with support walls perpendicular to the dam face, which provide additional lateral support. This reduces the volume of construction materials required in the main dam wall. From the intake pond, ductile iron pipes convey the harnessed water down to a six jet Pelton turbine on a vertical axis. The small powerhouses consist of a generator room and an adjacent smaller space housing a control room and a high voltage room.  All the powerhouses have the same dimensions and arrangement, and are built around the electromechanical equipment. The energy is delivered from the 6 kV generators via step-up transformers, 22 kV switchgear and transmission lines.

The hydroelectric projects are characterized by long pressure pipes of buried ductile iron. The two projects combined have about four kilometers of pipelines.
