Hyperscaler presence: Apple, Meta, and Google operate significant facilities drawn by green power and GDPR-aligned data privacy regulations.

Network connectivity: Strong interconnection to continental Europe through submarine cables.

Wind leadership: Among the world's highest wind energy penetration rates.

Infrastructure and connectivity

Power availability

Nordic grids support AI expansion that would strain continental European infrastructure:

Transmission capacity: Availability of 400kV corridors enables direct high-voltage connections for large facilities without costly grid upgrades.

Generation surplus: Norway and Sweden export substantial power to European markets, indicating headroom for domestic load growth.

Reliability: Hydro-dominated grids provide consistent baseload without intermittency challenges affecting wind/solar-heavy regions.

Network connectivity

Submarine cables: Multiple routes connect Nordic compute to UK, Germany, and broader European markets: - North Sea Connect (Norway-UK) - Multiple Baltic routes to Germany and Poland - Transatlantic connections through Iceland and Greenland

Latency considerations: Stockholm to Frankfurt: ~15ms; Oslo to London: ~20ms; Helsinki to Amsterdam: ~25ms. Acceptable for most AI inference workloads, though latency-critical applications may require continental European presence.

Bandwidth investment: Arelion's 2025 network upgrade creates AI "superhighway" connecting hyperscale facilities across Scandinavia to European demand centers.¹⁶
