Coffey Construction has undertaken power industry construction projects for over 30 years.  Our power industry projects have included:

  • Windfarm construction
  • Cable ducting for underground cables up to 110kV
  • Substations for electricity companies up to 220kV
  • Substations for the supply of electricity to new developments.

Coffey Construction built the first wind farm in Ireland, in 1992, at Bellacorick in County Mayo, where our work included erection of turbines, construction of access roads, sub-station and cabling and duct routes.  The largest turbines we have constructed were at Coomatallin in County Cork, where the project was to design and construct six 1 MW wind turbines, together with sub-station, cabling and extensive permanent access roads.

We have undertaken extensive underground cabling work for electricity supply companies as specific projects and as work incorporated into other infrastructure projects.  As an example, our Bishop O’Donnell Road Widening project incorporated approximately 3km of new 10kv, 38kv and 110kv ducting/cabling and the diversion of a further 2km of 11 0kV.  It is our preference to directly employ our site personnel, and we have used our multi-skilled resources to excavate and reinstate trenches, lay ducts and lay cables.  We employ specialists to undertake cable jointing and splicing work.

We have constructed sub-stations for the public distribution network and for supplies to development sites.  Our in-house electrical engineers have designed LV substations and Programmable Logic Controller panels for many of our infrastructure projects, including waste water treatment plants and for technology park infrastructure.
