Echelon DUB40
Grange Castle Business Park, Dublin, D22 A259, IE
Grange Castle and Clondalkin, in South Dublin, are where Echelon Data Centres places DUB40, the least documented of its four Irish projects. No capacity, timeline, grid position or street address has been published for it, and Echelon states around 400 MW across the four Irish sites together rather than site by site. The company's visible activity is elsewhere in the estate: DUB20 at Kish Business Park in County Wicklow was launched by the Taoiseach in May 2025 and broke ground that September at 200 MW, 90 MW of it in phase one, after a grid connection secured only in 2024 following an original 2021 target.
