The Project

Turlough Hill is a 292 MW pumped storage plant. The station entered into service in 1974 and today still provides vital benefits to Ireland’s electricity infrastructure, particularly as a peaking plant.

Our Approach

  • The Challenge

    All four 72 MW units required major investment to enable ESB to maximise its potential on the grid.

  • The Solution

    Project management oversight on the refurbishment of four pump-turbine generating units, including all Balance of Plant (BOP). The scope included preparation of enquiry documents, tendering, procurement and supervision of the primary EPC (Engineering, Procurement and Construction) Contract for the design, supply, installation and commissioning of replacement generator stators and full turbine refurbishment for all four units.

The Results
