The Pattack Hydro Project is a 2MW scheme located on the Ardverikie Estate near Loch Laggan in the central Highlands of Scotland.

A 6.5km pipe transfers water from a large dam to the powerhouse. This vertical drop, known as the 'Gross Head' of the project is 150m. The pipeline is made of Glass Fibre Reinforced Plastic (GRP). A Gilkes Francis solution is used, operating at a design flow of 1,600 l/s. This turbine is a reaction type turbine which is optimised for low-head, high-flow applications and provides high efficiency at peak power.

Construction mobilization started in early 2016. As well as being an investment partner in the project, Gilkes Energy is also the lead engineer, providing design, project management and construction supervision services during the construction phase, as well as managing the operation and maintenance of the facility thereafter. The lead civil contractor is TSL Contracting, an experienced civil contractor based on the Isle of Mull.

 

The project started generating in September 2017 and was delivered on time and on budget.
