EirGrid announces €1 billion procurement programme for offshore electricity grid

In 2021, Ireland opted to move towards a plan-led rollout of offshore renewables and infrastructure.

As part of that work, EirGrid as Ireland’s Transmission System Operator has been tasked with bringing forward a plan to deliver on the Government’s offshore ambitions.

Focused initially on Ireland’s east coast, and then moving to the south coast, the landmark procurement programme will relate to Operation & Maintenance (O&M) activities to enable the connection of offshore renewable generation to the onshore grid.

The contracts will encompass a minimum of eight O&M procurement categories covering the full spectrum of services required. These include:

• Inspection & Maintenance Support
• Marine Logistics
• Warehousing and Handling
• Subsea Inspection Repair & Maintenance
• Asset Health, Security & Operational Monitoring
• Training and Support Services
• Health, Safety & Environmental Support
• Helicopter Intervention Support (personnel winching and light cargo).

In addition, EirGrid is also today commencing another procurement initiative in relation to their Powering Up Offshore - South Coast Enduring Connection Policy (ECP) works, and the high voltage equipment aspect of these works.

Commenting on today’s announcement at the 2025 WindEurope conference in Copenhagen, EirGrid Chief Infrastructure Officer Michael Mahon said: “It is estimated that the procurements being launched today will be valued in excess of €1 billion, which truly demonstrates the intent to begin delivering offshore renewables at scale – a critical step towards a cleaner energy future for Ireland.

“I would encourage the entire supply chain in these areas to engage with EirGrid and help us to harness the significant offshore wind resource that exists in Irish waters.”
