Ireland's biggest projects — data centres, wind, solar & grid
The largest developments in the State are consented directly by An Coimisiún Pleanála under the Strategic Infrastructure process — bypassing the council registers entirely. We track every one, sized by megawatt capacity, so contractors and suppliers can target the projects that never show up in the ordinary planning lists.
