The Stank Burn hydro scheme is located in the Loch Lomond and The Trossachs National Park, just north of Callander. The project is situated on the Stank burn on Forestry Commission Scotland land that has been leased to Callander Community Hydro ltd, the company set up by the community trust to develop the hydro scheme.

As a conventional run of river hydro scheme, there is no dam or water storage, just a low height intake weir. This feeds a buried HDPE pressure pipe that runs down the hill to a timber clad powerhouse.
