River Lee

The River Lee Scheme is made up of two separate power stations:

Station: Carrigadrohid
County: Cork
Fuel type: Hydro
Capacity: 27MW
Status: Active
Commissioned: 1952

Station: Inniscarra
County: Cork
Fuel type: Hydro
Capacity: 27MW
Status: Active
Commissioned: 1952

Our Lee Hydro Stations span two locations at Inniscarra and Carrigadrohid in the Lee Valley, around 14 km from Cork City. Built between 1952 and 1957, they joined the schemes of the rivers Shannon, Erne and Liffey to become our fourth major hydroelectric development. This involved creating two lakes in the Lee Valley, which:

  • covers an area of 14km²; and
  • have a storage capacity of 45 million cubic metres.

Overall, the stations have a combined capacity of 27 MW. Inniscarra has two generating units: one produces 15 MW and the other produces 4 MW. Both units use Voith turbine with Brown Boveri generators, which operate under an average head of 30m. Carrigadrohid has one generating unit (Voith turbine/Siemens generator) with a capacity of 8 MW, operating under an average head of 13m.

  1. My father Jim Greene worked at the dam in Inniscarra
    As an engineer until his death in 1979. I would love
    To see some photos of him there if there are any.

  2. My father John (Jackie) O Sullivan died as the result of an accident during the construction of the Dam at Carrigadrohid. I was wondering if there is any Literature (Photos) referring to this.
