The Project

Cathaleen’s Fall is a critical asset in the ESB’s hydroelectric power generation portfolio. The station provides key benefits to Ireland’s electricity infrastructure, including a black start capability, flexible cover for increased renewable penetration and low marginal cost and carbon free electricity generation.

Our Approach

  • The Challenge

    Initially put into operation in 1951, both units required significant investment to enable ESB International to capitalise on the available natural resource to provide customers with renewable power.

  • The Solution

    Full project management on the refurbishment of two Kaplan turbine generating units, including all Balance of Plant (BOP). Document preparation, procurement and EPC contract supervision for the design, supply, installation and commissioning of replacement generators and turbine refurbishment.

The Results

  • Installation of new AVR and ​digital ​governor
  • New automated control system allowing monitoring of the complete plan
