Network & Connectivity Ecosystem
As a regional hub, Letterkenny offers reliable connectivity, though its ecosystem is more focused than that of a primary international market like Dublin.
-
Carrier Density & Carrier Neutrality: The market features access to Ireland's national carriers, with at least one provider offering services locally, as of September 2025. While carrier density is not high, connections to the national fiber backbone provide sufficient diversity for most enterprise needs.
-
Direct Cloud On-Ramps: There are no direct cloud on-ramps within Letterkenny, as of September 2025. Businesses connect to cloud providers via the primary data center hub in Dublin, accessible through national network links and private line services.
-
Internet Exchange Points (IXPs): Public peering is handled through INEX in Dublin. Most traffic in Letterkenny is routed through the national capital, though private peering arrangements can be established.
-
Bare Metal: Bare metal server options are available from providers who serve the broader Irish market. Services from companies like Leaseweb can be deployed to serve workloads in the region.
Power Analysis
-
Average Cost Of Power: Industrial electricity rates typically fall between €0.18 – €0.24 / kWh, as of September 2025. This pricing is competitive for a European location with a high percentage of renewable energy in its grid mix.
-
Power Grid Reliability: The local grid is stable and part of Ireland's national power infrastructure. The grid benefits from a mix of approximately 40% renewables (mostly wind) and 60% fossil fuels, providing a reliable power supply for business operations.
Market Access, Business & Tax Climate
-
Proximity To Key Business Districts: Data centers in Letterkenny are well-positioned to serve County Donegal, the largest county in Ulster, and key regional business parks. The location provides a crucial link for cross-border trade and services with nearby Northern Ireland.
-
Regional Market Reach: Letterkenny effectively serves as a digital hub for the entire Northwest of Ireland. Its location reduces latency for end-users in the region who would otherwise be served exclusively from Dublin.
-
Tax Advantage For Data Centers: Ireland offers specific tax advantages that can benefit data center operators and their clients. A key incentive is a potential exemption from the standard 23% VAT on the purchase of qualifying data center equipment, which significantly lowers capital expenditure.
Natural Disaster Risk
Letterkenny has a very low natural disaster risk profile, with an INFORM Risk score of 2.1 out of 10, as of September 2025. This score indicates a highly stable and safe physical environment for critical infrastructure.
The primary environmental hazards to consider are localized flooding events. Key risks include:
- Coastal Flood: The most significant risk, due to proximity to Lough Swilly.
- River Flood: A moderate risk factor for specific areas.
- Tsunami: A low but present risk for coastal regions.
Risks from earthquakes, tropical cyclones, and droughts are negligible.
