Prior Information Notice: Offshore Transmission Infrastructure Opportunities
EirGrid has published a Prior Information Notice (PIN) - 137262-2026 - Planning - TED - to inform the market of upcoming procurement activities for offshore transmission infrastructure under the Powering Up Offshore South Coast programme.
The PIN has been issued to raise industry awareness of future opportunities and to advise suppliers of the need to register under the relevant product and service codes within the Achilles Supply‑Line Qualification System.
This Qualification System will act as the mechanism through which economic operators may express interest and pre‑qualify for future competitions.
Qualification System
EirGrid intends to utilise an established Qualification System (QSN) for suppliers of offshore transmission infrastructure. The Qualification System is continuously open, and registration details can be found at the Achilles Supply‑Line site via this link.
Suppliers wishing to participate in upcoming procurement processes must be registered under the appropriate product and service codes. Suppliers already registered under the correct codes do not need to take further action at this stage.
