Onshore Construction Start

DELAYED +2yr (Apr 2026): The developer’s project-delivery page indicates Codling Wind Park construction could begin in 2027 and take two to three years, covering both offshore and onshore works. In reality, the planning application for the full project (including the Poolbeg onshore substation and cables) was only submitted in September 2024, and in December 2025 An Coimisiún Pleanála issued a detailed Further Information Request, showing that planning consent and detailed design are still in progress. Onshore construction is therefore unlikely to commence as early as 2027; aligning its start to around mid‑2028 better reflects the consenting status while remaining broadly consistent with the developer’s 2–3 year construction duration. --- Onshore transmission works for Codling Wind Park, comprising three 220 kV onshore export cables from landfall on the southern Poolbeg peninsula to a new onshore 220 kV substation and onward connection into the existing Poolbeg 220 kV substation, are planned to begin construction in the 2026–2027 period in line with the overall project construction window, subject to planning permission and other consents. These works will establish the onshore interface of the Codling–Poolbeg export connection needed to deliver up to about 1.3–1.45 GW into the Irish grid.
