Offshore wind farm

In accordance with the provisions of the 1991 United Nations Economic Commission for Europe Convention on Environmental Impact Assessment in a Transboundary Context (“the Espoo Convention”), the Minister for Housing, Local Government and Heritage received notification from the UK Planning Inspectorate (“PINS”) in relation to a development consent application (“the planning application”) by Mona Offshore Wind Limited. Mona Offshore Wind Project is a project comprised of (but not limited to) an offshore wind farm array located approximately 28.2km from the Anglesey coastline in the Irish Sea, offshore transmission infrastructure extending to landfall on the north coast of Wales; and an onshore transmission infrastructure extending from landfall to the onshore National Grid substation at Bodelwyddan. 

For the purposes of Regulation 32 of the Infrastructure Planning (Environmental Impact Assessment) Regulations 2017 (the 2017 EIA Regulations) the United Kingdom Secretary of State has conducted transboundary EIA screening. This screening exercise determined that the proposed development may have transboundary environmental impacts in this State. The transboundary issues screened in include significant impacts on shipping and navigation.

The screening assessment is available at:
