KGAL designs meet the needs of Europe's leading hydropower market.

Norway is the largest producer of hydropower in Europe; its total output meets over 98% of the country's electricity demand. Helping to maintain that delivery is the Nordic Investment Bank, which is co-financing the refurbishment of three hydropower projects in mid-Norway.

One of these projects is Byafossen, a plant run by NTE Energie AS, one of Norway's largest electrical contractors, and Norwegian energy infrastructure specialist, HMR Husnes, is helping with the refurbishment.  KGAL has a long-standing history of partnership with HMR across a number of projects in and around Norway, mostly within the hydropower sector and, on this job, we were contracted to provide the designs for four wheeled/roller vertical shut off gates and associated trash racks, and a bypass flap valve gate.

The roller gates are each approximately 4.8m sq and the trash racks are 4.6m wide and 6.4m tall.  Our design work was largely influenced by the environment; the station is located in a national salmon river and, on completion, conditions for salmon will be improved.

KGAL delivered a complete package of detailed manufacturing drawings ready to be issued to the workshop.  The components were fabricated by HMR in Riga, Latvia, and installation is now in progress.
