Pattack Hydro Scheme

The Pattack hydro project is the largest storage project to be built in the Scottish highlands in recent years, and is the third scheme that Gilkes have been supplied equipment to on the Ardverikie estate. Previous schemes were in 1935 and 1986.
The project has a new mass concrete dam utilising 3,300m3 of concrete. It has created a new small lochan by impounding 196,000m3 of stored water, which is delivered to the turbine via a 6,500m penstock pipe.
Due to the storage element of this scheme Francis turbines were selected as the most suitable, achieving a peak efficiency of over 92%. The Gilkes designed control system employs sophisticated programming and algorithms, fine-tuned on site by Gilkes commissioning team, to maximise the storage potential of the site.
SCOPE OF SUPPLY: Full water to wire package including:

The small footprint of the Francis turbines, and by close co-operation with the civils designers, enabled the powerhouse size to be minimised and also partially buried. This minimises any visual impact in this beautiful area.
The Ardverikie estate, on the shores of Loch Laggan, is a popular film location and has made appearances in several films and TV series.
