Tullamore 110 kV Substation

Civil Works for 110 kV AIS Loop-In Substation

Location: Listowel, Co. Kerry

Supporting Renewable Integration with Expert Civil Delivery

Collins Building & Civil Engineering Ltd was appointed to carry out civil engineering works on the Tullamore 110 kV substation near Listowel. The development forms part of a strategic loop-in/loop-out connection for renewable energy integration in the southwest grid.

Scope of Works

In collaboration with key stakeholders including ESB Networks and engineering consultants, Collins BCE completed:

  • Site Preparation & Bulk Excavation
    Earthworks on greenfield agricultural land, with protective measures for watercourses and natural heritage features.
  • Reinforced Substation Foundations
    Construction of concrete bases for switchgear, control buildings, and transformer bays, including all associated ducting.
  • Stormwater & Environmental Drainage
    Sustainable drainage solutions designed for runoff control and environmental compliance near the River Galey.
