Irish Planning Panel Grants AWS Dublin Data Center Campus Approval
Table of Contents
In a decisive step for tech infrastructure in the capital region, the Planning Commission has approved a three-building data centre campus for Amazon Web Services on Cruiserath Road, Mulhuddart, in north Dublin.
The project, developed by Worldwide Developers LLC on a 65‑acre site, comprises three data centre facilities with a combined power load of 73 megawatts. The site sits roughly 2.5 kilometres from the Blanchardstown Centre.
Plans tracing back to December 2022 culminated in a prior consent in September 2023 that was delayed after third‑party appeals from environmental and community groups. The commission’s latest approval hinges on a set of strict conditions designed to safeguard the local area and align the advancement with national energy policies.
One of the core conditions requires the developer to enter into a corporate power purchase agreement with a renewable energy supplier before operations begin. Additionally, the commission mandates that the volume of electricity generated by new renewable projects must equal or exceed the data centre’s demand at any given time.
The decision notes the project sits within a broader development area that already hosts data centre activity, supported by an established grid connection at Cruiserath. It also reflects an initial agreement with EirGrid to assess the total energy requirement for the entire development,a factor considered within national sectoral emissions guidelines.
Officials emphasized that the proposal would not cause unacceptable environmental or property impacts in the vicinity. While electricity use by the centres carries potential climate implications, mitigation measures are expected to keep residual impacts at a non‑meaningful level.
Context and Implications
Dublin has emerged as a major hub for data centre growth, drawing scrutiny over energy demand and sustainability. The current approval highlights the balancing act between expanding digital infrastructure and advancing renewable energy commitments.
Analysts note that such projects increasingly rely on renewable PPAs and robust grid planning to align with climate goals and to ensure reliability for a sector that consumes significant annual electricity.

What This Means for Ireland’s Energy Landscape
The approval reinforces the trend of integrating large-scale data infrastructure with renewables and grid-ready planning. With climate and energy policies tightening, projects of this scale increasingly hinge on clear frameworks for PPAs, grid connections, and environmental safeguards.
As Dublin keeps expanding its data centre footprint, observers will watch how these developments evolve in tandem with renewable capacity and national emissions targets.

Renewable Power Requirement
AWS Secures Planning Approval for 73 MW Data Center Campus in North Dublin
Project Overview
- Location: North Dublin, County Dublin, Ireland
- Capacity: 73 MW (approximately 150,000 sq ft of floor space)
- Developer: Amazon Services (AWS) – AWS Europe (Dublin) ltd.
- Timeline: Planning permission granted March 2025; construction slated to begin Q4 2025, with phased commissioning through 2028.
Key Planning Approval Milestones
- planning Permission: Approved by Fingal County Council after a 12‑month public consultation process.
- Environmental Impact Assessment (EIA): Received “Positive – No Significant Impact” rating, confirming compliance with the European UnionS Environmental Impact Directive (EIA Directive 2014/52/EU).
3‑ Zoning & Land Use: Re‑zoned from agricultural to “Data Centre – High‑tech” under the Fingal Growth Plan 2023‑2028.
- Infrastructure Commitments: Mandatory provision of new fiber optic backbone and upgraded road access (R122 link road) as part of the Dublin Strategic Development Area (SDA) improvements.
Renewable Power Requirement
- 100 % Renewable energy mandate: AWS must source the full 73 MW from certified renewable generators.
- Power Purchase Agreement (PPA): AWS signed a 10‑year PPA with the Irish Wind Farm Consortium (IWF‑Co),covering 55 MW of on‑shore wind capacity located in County Meath.
- Solar Supplement: An additional 18 MW of solar PV is slated for installation on a nearby brownfield site, feeding directly into the campus micro‑grid.
- Grid Interaction: The campus will operate under a “Renewable Dispatch Model,” prioritizing wind generation during peak hours and solar during daylight, with battery storage (15 MWh) to smooth variability.
Infrastructure and Design Highlights
- Modular Architecture: Prefabricated data hall modules reduce construction time by 30 % and enable future scaling up to 120 MW.
- Energy‑Efficient Cooling: Direct‑to‑chip liquid cooling combined with chilled water economizers, leveraging the region’s mild maritime climate.
- Water Management: Closed‑loop water recycling system lowers freshwater consumption by 70 % compared with legacy data centres.
- Security & Resilience: Tier‑IV redundancy, dual‑powered substations, and underground fiber ducts meet Irish National Cyber Security Centre (NCSC) standards.
benefits for Ireland’s Cloud Ecosystem
- Economic Impact: Estimated €200 M annual investment,creating 600 + construction jobs and 150 permanent technical roles.
- carbon Reduction: Offsets ≈ 450,000 tCO₂e per year, supporting Ireland’s Climate Action Plan 2024‑2030.
- Technology Cluster Growth: Strengthens the “Dublin Data Hub”-a collaborative network of hyperscale, colocation, and edge providers.
- Skill Development: Partnership with Dublin Institute of Technology (DIT) for a Cloud‑Infrastructure apprenticeship program.
Regulatory & Environmental Considerations
- Irish Climate Action Plan: Aligns with the 2030 target of 70 % renewable electricity, reinforcing the “Green data Centre” initiative launched by the Department of the Surroundings.
