Nantes is a key digital gateway for Western France, providing an excellent alternative to the congested Paris market. It is the ideal location for businesses requiring low-latency connectivity to the Atlantic coast and the Pays de la Loire region. The city's low disaster risk profile and stable, nuclear-powered energy grid make it a top choice for workloads demanding high availability and predictable uptime.

Nantes: At A Glance

Network & Connectivity Ecosystem

Nantes provides a solid connectivity foundation for serving France's western corridor, acting as a crucial secondary hub to Paris.

Carrier Density & Carrier Neutrality: The market includes access to over 10 national and regional carriers, as of September 2025. Carrier-neutral facilities ensure competitive interconnection options for building resilient networks.

Direct Cloud On-Ramps: The area has over 1 direct cloud on-ramp, enabling access to 1 cloud region as of September 2025. Low-latency, private connections are locally available to Google Cloud (GCP). Access to other major cloud providers is achieved via private network extensions to primary hubs in Paris.

Internet Exchange Points (IXPs): While some private peering occurs locally, the primary hub for public peering in France is Paris. Most networks in Nantes establish private interconnects or leverage transit to Paris for exchanging traffic with major content and access networks.

Bare Metal: Bare metal server capacity is readily available from multiple providers in the Nantes market. Providers like OVHcloud offer dedicated server solutions for compute-intensive workloads that require direct hardware access.

Power Analysis

France’s power infrastructure is a significant strategic advantage, offering high reliability at a competitive cost.

Average Cost Of Power: Industrial power rates in the region typically range from €0.16 – €0.22/kWh, as of September 2025. This stable pricing helps ensure predictable operational expenses for high-density compute environments.

Power Grid Reliability: The national grid is exceptionally reliable, with approximately 68% of its power generated from nuclear sources as of September 2025. Data centers in Nantes benefit from this stability, with facilities engineered with redundant connections to the grid to support mission-critical uptime.

Market Access, Business & Tax Climate

Nantes offers strategic access to a significant economic region with a supportive business environment.

Proximity To Key Business Districts: Data centers in Nantes are strategically located to serve the region's strong aerospace, advanced manufacturing, and technology sectors. This proximity allows businesses to run latency-sensitive applications close to their operations and user base.

Regional Market Reach: The market provides effective, low-latency coverage for Western France, including the Brittany and Pays de la Loire regions. It is an optimal location for content delivery, disaster recovery, and edge computing for millions of consumers outside the Paris metropolitan area.

Tax Advantage For Data Centers: While France does not offer broad, standing tax incentives, it provides significant project-specific financial support. Favorable long-term loans from institutions like the European Investment Bank can be secured for major data center investments, substantially reducing the capital cost of large-scale deployments.

Natural Disaster Risk

Nantes has a low overall risk profile, making it a secure location for critical infrastructure.

The region's overall INFORM risk score is Low (2.7/10), as of September 2025. This indicates minimal exposure to a combination of natural and human-made hazards. The primary environmental risks to engineer for are hydrological.

Key potential hazards include:

• River Flood: The highest individual risk factor, related to the Loire River.
• Coastal Flood: A moderate risk due to the city's proximity to the Atlantic coast.
• Earthquake: A very low and non-critical risk factor.
• Drought: A minor risk factor.
