Culligran power receives water from the outflow of Beannachran reservoir (see separate item) with the water conveyed along a tunnel and pipeline to reach the station, with a semi submerged surge tower behind the station to protect the turbine from any sudden changes in level. The station houses a single 19 Megawatt turbine (half the capacity of Deanie) in an underground chamber hollowed out from the bedrock. The turbine hall is reached by a long sloping vehicular access passage the upper end of which is marked by an arched entrance with relief carving of lettering identifying the station. This station is a good example of a medium sized underground station. Where it was possible to build them underground stations were utilised on this scheme because of concerns that the development of hydro in this area would have a negative effect on the scenic amenity. In line with the wishes of James Shearer local stone was used as widely as possible during construction and it is likely that the stone for the construction of the arched entrance was salvaged from the excavations for the main chamber.
