The US has long seen Greenland as key to the defence of its mainland, and former war plans listed Greenland as one of the territories the US would seize and fortify to defend itself in a hypothetical war.
Beneath the headlines, however, lies a more substantial question for the telecom and technology sectors: how might Greenland’s geography, resources, and infrastructure shape future networks, supply chains, and digital resilience?
For operators, subsea investors, and hyperscalers, the Arctic isn’t just a remote blank space. Melting sea ice, shifting trade routes, and the search for diversified technology supply chains are gradually pulling Greenland into discussions about connectivity, energy, and data strategy.
Greenland’s strategic location
Greenland occupies a unique position between North America and Europe, directly along great-circle routes that could shorten communication paths between major hubs. Existing transatlantic cables run further south, but as demand for lower latency and route diversity grows, analysts are exploring northern paths that were once considered impractical. While no commercial transatlantic cables currently land in Greenland, feasibility studies highlight its potential value for future networks.
Domestically, Greenland relies on a combination of satellite services and a handful of subsea links to connect its dispersed communities. Any new international cables would likely integrate domestic access, presenting opportunities for operators to collaborate with local authorities on hybrid commercial-development models.
Energy and the potential for digital infrastructure
Greenland has significant untapped renewable energy potential, particularly in hydroelectric power, and a growing interest in wind generation. For an industry under increasing pressure to decarbonise, the combination of clean power and naturally cool temperatures is attractive for data centre development.
At present, the territory’s only major data centre initiative is being developed by local operator Tusass in Nuuk, focused on improving domestic connectivity. While large-scale international data centre projects have not been publicly confirmed, Greenland’s energy and climate conditions could support such developments in the future, provided that connectivity and power infrastructure scale accordingly.
Minerals underpinning technology
Perhaps the most immediate technology-driven factor in Greenland’s strategic relevance lies beneath the surface. The territory hosts deposits of rare earth elements and other critical minerals used in semiconductors, batteries, and advanced electronics. Western governments are actively seeking to diversify supply chains away from reliance on a small number of dominant producers, particularly in Asia.
For the telecom sector, secure access to these materials is directly relevant to the production of base-station radios, fibre-optic components, and other critical hardware. Mining projects remain at early stages and are subject to environmental scrutiny, but any significant development would require modern ports, power systems, and communications networks: infrastructure that operators could help deliver.
Security and dual-use infrastructure
The U.S. maintains a strategic installation at Pituffik Space Base (formerly Thule Air Base) in northwest Greenland, supporting missile warning and space surveillance operations. These installations are connected to global defence networks, and while they are primarily military in purpose, they highlight the Arctic’s value for high-latitude infrastructure, including telemetry and satellite ground stations.
Local leaders have emphasised civilian development and environmental protection, so dual-use infrastructure, where networks serve both commercial and government purposes, would need to balance strategic utility with domestic priorities.
Commercial and logistical realities
Despite the territory’s strategic appeal, Greenland presents significant logistical and economic challenges. Its population is just over 57,000, dispersed across vast distances with limited road connections. Harsh weather, short construction seasons, and high transport costs complicate large-scale infrastructure projects. Regulatory processes are evolving as Greenland seeks greater economic autonomy from Denmark.
Any project would therefore require long-term anchor customers or public-private partnerships to be commercially viable. While discussions of northern subsea routes and energy-driven data centres are ongoing, concrete investment decisions remain in early stages.
Why should the industry pay attention?
Even in the absence of immediate megaprojects, developments in Greenland highlight several trends relevant to operators and network planners:
Route diversity as resilience: Geopolitical tensions and network disruptions have prompted operators to reconsider concentration risk. Arctic routes, though currently speculative, could become part of a more distributed transatlantic network in the future.
Integration of energy and networks: Location decisions for digital infrastructure increasingly follow renewable power availability. Regions offering both clean energy and potential fibre connectivity may gain strategic leverage.
Supply chain security: Access to critical minerals is a growing concern for telecom hardware. Greenland’s mineral resources could shape future supply strategies and infrastructure planning.
Greenland will not transform global telecoms overnight. Nevertheless, it sits at the intersection of multiple forces, digital growth, climate change, and strategic competition, that are reshaping how networks and supply chains are planned.
