Zagreb – Gateway to the Balkans and Adriatic

Zagreb: Strategic Hub for Southeast Europe

Zagreb serves as the vital interconnection point for enterprises bridging the gap between Central European networks and the Balkan Peninsula. This market is a primary choice for operators requiring a renewable-heavy power grid to secure regional dominance and provide low-latency services to the Adriatic coast. Zagreb remains the definitive core for securing a resilient digital footprint across Croatia and neighboring emerging markets.

Zagreb: At A Glance

Network & Connectivity Ecosystem

Zagreb acts as the primary networking hub for Croatia, offering essential transit routes between the Mediterranean and Central Europe.

Carrier Density & Carrier Neutrality: Carrier count: over 15 as of September 2025. The market hosts 15–20 providers offering competitive local loops and long-haul transport. Carrier neutrality is standard among major facilities, allowing for flexible provider selection and reliable network design.

Direct Cloud On-Ramps: 0, enabling access to 0 cloud regions as of September 2025. There are currently no direct on-ramps for major clouds like AWS or Microsoft Azure within the city limits. Connectivity is managed through network service providers extending from primary hubs in Vienna.

Internet Exchange Points (IXPs): The Croatian Internet eXchange (CIX) is the central peering point for the region as of September 2025. It keeps local traffic within national borders to improve latency and reduce transit costs for regional service providers.

Bare Metal: General availability for high-performance hardware is supported by various managed service providers as of September 2025. Global entities like Hivelocity represent the standard for supporting regional compute requirements with dedicated hardware.

Power Analysis

Energy availability in Zagreb is defined by a commitment to sustainable sources and a modernized urban grid.

Average Cost Of Power: Industrial electricity is priced at €0.28/kWh as of December 2023. This cost is tied to a grid where 68% of the energy comes from renewables, offering a stable environment for carbon-conscious operations. This pricing reflects a stable energy market relative to other European capitals with similar renewable ratios.

Power Grid Reliability: The grid in key data center corridors is well-engineered and utilizes multi-substation support. Reliability remains high, as the infrastructure is built to handle the specific demands of industrial and telecommunications loads as of September 2025.

Market Access, Business & Tax Climate

Zagreb provides a centralized base for digital operations serving the Western Balkans and the Adriatic coast.

Proximity To Key Business Districts: Data centers are located near the Buzin business zone and the Selska area as of September 2025. This proximity is vital for the financial and technology sectors that require fast physical access for maintenance and minimal latency for local operations.

Regional Market Reach: Zagreb serves as the primary gateway for the Croatian population as of September 2025. It is also a strategic starting point for digital services targeting Slovenia, Bosnia and Herzegovina, and Serbia.

Tax Advantage For Data Centers: There are no specific tax incentives for the data center industry as of September 2025. Businesses operate under a predictable fiscal environment that supports long-term planning without industry specific subsidies.

Natural Disaster Risk

Zagreb is classified as Low risk with a score of 2.5/10 as of December 2023. The risk profile is manageable for mission-critical infrastructure when standard mitigation strategies are applied.

• River Flood (6.8): This is the primary hazard, requiring specific site selection and elevation measures as of December 2023.
• Earthquake (5.6): A moderate risk that demands seismic structural standards in facility construction as of December 2023.
• Drought (3.3): A minor risk with limited impact on modern cooling technologies as of December 2023.
• Regional Hazards: Risks such as Tsunami (5.8) and Coastal Flood (5.0) are regional factors for the Adriatic coast and do not materially impact inland Zagreb infrastructure as of December 2023.
