Irish substation & switchgear tenders
Live tenders for HV/MV substations, GIS and AIS switchgear, and transformer works — auto-matched from TED daily.
Weekly Brief
Updated 2026-04-25Substation works in the Irish pipeline are dominated by EirGrid's 110 kV → 220 kV uplifts in the Greater Dublin and East Midlands regions, where data-centre cluster demand has pushed several traditional 110 kV nodes past firm-capacity limits. New-build 220 kV GIS (gas-insulated switchgear) substations typically run €15-40m and pull a narrow tier of bidders — Siemens Energy, Hitachi Energy, GE Vernova on the OEM side, with a sub-tier of Irish civils contractors handling enabling works. Look for AIS (air-insulated) at smaller-scale 110 kV reinforcements and GIS at urban, density-constrained sites where land take is the binding constraint.
Auto-populated from TED (Irish notices). Substation works often appear as part of broader transmission packages; deadlines and lot structures should be verified on the official notice.
