The 130kW hydro plant is located at the An t-Sreang burn, above Arrochar, in Argyll & Bute, Scotland.
Originally, planning permission for the Project was obtained in July 2015 for a larger hydro project at the same location. Site investigations revealed ground conditions which potentially made this larger project unviable. The project was redesigned in light of these ground conditions and the size reduced to 130kW. The project was granted a CAR licence from SEPA and grid connection permission from SSE Power Distribution.
The Civil Engineering works comprise:
- an intake weir to abstract water from An t-Sreang;
- 578m of pipeline 400mm diameter;
- a powerhouse to house the turbine and ancillary equipment; and
- a tailrace pipeline and outfall to return water to An t-Sreang.
The scheme is predicted to produce an energy yield of 411,970 kWh in a year of average rainfall.
Actual output from July 2018 to June 2019 was 355,822kWh. June & July were well below budget due to the drought during the summer of 2018.
