Arelion unveiled a major upgrade to its Scandinavian fiber network, targeting the surge in hyperscale data center and AI infrastructure demand across the Nordics. The company will install new high-fiber-count cables in existing ducts linking Stockholm, Oslo, and Copenhagen, securing long-term fiber availability while avoiding the environmental impact of fresh duct construction. The project is scheduled for completion in 2026, with additional regional upgrades planned through 2027.
The expansion builds on Arelion’s 25-year-old duct network, originally deployed as Telia International Carrier, which already connects to 13 subsea cables serving the Nordics and Baltics. By adding new fiber capacity and building last-mile infrastructure to hyperscale data centers, Arelion aims to reinforce network resilience and offer customers direct connectivity into Europe, North America, and global cloud platforms. Scandinavia has become a strategic hub for data centers due to stable energy prices, renewable power availability, and abundant land. Analysts forecast Nordic data center capacity will expand by 280–580 MW annually, with market revenues projected to reach $7.38 billion by 2030.
AI growth is accelerating in parallel. Industry estimates place Scandinavia’s AI market on a 26% compound annual growth rate, reaching nearly $20 billion by 2031. Arelion’s fiber expansion positions it to capture this demand, while extending services such as IP Transit, Wavelengths, DIA, Cloud Connect, Ethernet VC, and DDoS mitigation across its global backbone.
- New high-fiber-count cables installed in ducts between Stockholm, Oslo, and Copenhagen
- Completion expected by 2026; further upgrades planned into 2027
- Builds on Arelion’s duct network and access to 13 subsea cables
- Nordic data center market projected to grow 280–580 MW per year; $7.38 billion by 2030
- Regional AI market projected to reach $19.9 billion by 2031
“By anticipating future demand rather than reacting to it, we built the infrastructure foundation that’s now critical for supporting the AI growth in the Scandinavian region,” said Daniel Kurgan, CEO at Arelion. “Installing new cables in our existing ducts will also minimize the impact on the environment compared to constructing a brand-new duct and cable system.”
🌐 Analysis: The Nordics have emerged as one of Europe’s most attractive regions for hyperscale and AI data center deployments, driven by stable power pricing, access to renewable energy, and favorable policy conditions. Arelion’s move highlights the growing demand for fiber backbones linking Nordic hubs to global networks, complementing new subsea routes such as Havfrue and Polar Connect. With hyperscaler AI clusters consuming massive bandwidth, fiber upgrades are essential to ensure low-latency connectivity and supply chain resilience. Competitors including GlobalConnect and TDC Net are also investing heavily in Nordic backbones, but Arelion’s long-established duct assets give it a strategic cost and time-to-market advantage.
