Clean Energy on the Horizon

Mac Lir is a proposed renewable energy development located in the Irish Sea, off the coast of counties Wicklow and Wexford.

About the project

At its nearest point, Mac Lir will be over 22km off the east coast, lying entirely outside Ireland’s 12 nautical mile foreshore limit. The project has the potential to deliver enough renewable energy to power over 600,000 households each year, helping Ireland to meet its binding target to reduce greenhouse gas emissions by 51% by 2030.
