Kangerlussuaq, Greenland’s Data Center Moment Has Been Decades in the Making

A Location Chosen Twice

Kangerlussuaq translates simply as “big fjord” in Greenlandic. The settlement sits at the head of a 190-kilometer arm of seawater that cuts deep into Greenland’s southwest interior, where the climate is drier and more continental than the coasts, fog is less persistent, and the weather, by Arctic standards, is almost cooperative. They are precisely why people keep coming back to build things here.

Long before the infrastructure arrived, the area served as a hunting ground for Paleo-Eskimo and Dorset culture peoples who tracked the large caribou herds that still migrate through the valley. It never became a major permanent settlement, the inner fjord location lacks the marine mammal access that sustained coastal Inuit communities, but the land was known, traversed, and used. The geography alone made it useful.

Bluie West Eight: America’s Arctic Staging Point

In 1941, the United States signed the Defense of Greenland Agreement with Denmark, then occupied by Germany, and began construction of what would become Bluie West Eight (BW-8), a major U.S. Army Air Forces installation at the head of the Kangerlussuaq fjord. The logic was coldly practical: the long, calm fjord created a natural approach corridor; the stable interior weather gave pilots a reliable window; and the location sat directly on the great circle routes connecting North America to the European theater.

BW-8 became an important Arctic staging point in the North Atlantic air network during the war years, valued not just for its position on the route, but for its role in logistics, refueling, weather support, and keeping operations moving in a harsh environment.

Sondrestrom and the Cold War Watch

After a brief post-war interlude, the base returned to American military hands during the Korean War era as Sondrestrom Air Base, a forward installation in NATO’s Arctic defense architecture. For four decades, Sondrestrom functioned as a self-contained Arctic support base: a refueling point, logistics platform, radar-support hub, and staging location for wider High North operations. At its peak, Sondrestrom supported over a thousand personnel in a location that has no agricultural land, no local supply chain, and no road connection to anywhere.

The base was sustained entirely by air and sea logistics. It built its own power generation. It operated its own fuel depot, its own maintenance facilities, its own communications infrastructure. This was not improvisation, it was deliberate construction of a self-contained operational environment in one of the most remote locations on the planet. The engineering problems were solved. The supply chain was worked out. The answer to “can you build and sustain something large-scale here” was answered definitively, across four decades of continuous operation.

The 1992 Handover and the Civilian Inheritance

The Cold War ended. In 1992, the United States handed Sondrestrom Air Base to Denmark and Greenland. The infrastructure, the long military-grade runway, the fuel storage, the power systems, the hangars, the accommodation blocks, was too valuable to demolish. It was converted to civilian use and became Kangerlussuaq International Airport, which for decades served as Greenland’s primary international aviation hub. The runway that once handled F-102 interceptors could accommodate widebody jets that no other Greenlandic airstrip could receive. Nearly every international visitor to Greenland transited through here.

That role changed in late 2024, when Air Greenland shifted its hub structure to Nuuk after the capital’s new Atlantic airport opened.

The New Mission: Compute at Scale

Which brings us to 2026, and a proposal that sounds improbable until you understand the history.

Drew Horn, CEO of GreenMet and a former senior aide to Vice President Mike Pence, has been developing plans for what he describes as a phased gigawatt-scale data center campus at Kangerlussuaq, starting at 300 megawatts by mid-2027 and scaling to 1.5 gigawatts by end of 2028. If completed at full scale, it would rank among the largest data center installations on the planet, built in a settlement of approximately 500 people at the end of an Arctic fjord.

The instinctive reaction “this is a stupid, impossible task” misreads the situation. The objection assumes you would be starting from nothing. You would not. The runway is there. The fjord access is there. The Arctic operating history is there. What is not fully there yet is hyperscale power and fiber. Those would still need to be built, permitted, financed, and connected.

The hydropower potential, at Tasersiaq and Tarsartuup Tasersua among other sites, is there. The engineering precedents, for building and sustaining industrial-scale operations in this exact location under Arctic conditions, were written across fifty years of continuous military operation.

Horn’s plan calls for LNG barges to power the initial 300MW phase while permitting for a dedicated hydroelectric facility is pursued for the scale-up. Related announcements around the Kangerlussuaq proposal have also included plans for hydropower and a subsea cable, though key approvals and applications are still outstanding.

Not everyone is convinced the timeline is realistic. Naaja Nathanielsen, Greenland’s minister responsible for business and energy, called the proposal “birds on the roof” a Danish idiom for “wishful thinking.” Her skepticism wasn’t directed at the concept but at the calendar.

What the Hyperscalers Already Know

The AI infrastructure arms race has made data center siting a strategic problem on par with energy policy. Data center deals globally hit a record $61 billion in 2025, with Meta, Microsoft, Google, AWS, and OpenAI competing for sites and power in a market where traditional locations, Northern Virginia, Dublin, Singapore, are running out of available electricity. The constraint is not capital. The constraint is power and cooling.

Kangerlussuaq clearly addresses cooling. Its long-term power case is more conditional: Greenland’s hydropower potential is substantial, but the industrial-scale generation and transmission needed for a campus of this size would still have to move from concept and tender into actual buildout.

The geographic positioning supports the argument for transatlantic relevance. But that advantage would only become commercial in the way hyperscalers care about if new fiber capacity is actually built into Kangerlussuaq rather than assumed.

The Real Obstacles Are Not Engineering

The challenges facing the Horn proposal are real, but the hardest ones now are not engineering alone. Arctic construction is capital-intensive and the build season is short, but those are known constraints. The harder variables are permitting, financing, and the geopolitical context surrounding Greenland.

Layered onto this is the broader geopolitical turbulence around U.S.-Greenland-Denmark relations, which has complicated every American private-sector initiative on the island regardless of its merits. The Trump administration’s stated interest in acquiring Greenland has made Greenlandic and Danish officials cautious about what they are seen to be approving, and for whom. That caution is likely temporary, the underlying economics and the infrastructure reality do not change, but it is a real headwind in the near term.

The Throughline

In 1941, American planners looked at the head of a remote Arctic fjord and saw what others missed: a location with the right climate, the right geography, and the right position on the routes that mattered. They built a base capable of supporting industrial-scale operations in conditions most engineers considered prohibitive. They solved the logistics, built the infrastructure, and sustained it for fifty years.

The next generation of planners is looking at the same coordinates and seeing the same things: stable climate, favorable geography, positioning on the routes that matter now, the data routes connecting North America and Europe, and a power profile that the rest of the world is increasingly unable to match.

The base at the end of the fjord was always meant for this kind of mission. The mission has simply changed.
