Greenland is not really a single energy system but a set of around 70 standalone microgrids strung along the coast. The larger settlements run on hydropower at five plants (Buksefjord, Tasiilaq, Qorlortorsuaq, Sisimiut, Ilulissat), with diesel generation serving the rest, and the renewable share is set to rise towards 90 per cent over the medium term as planned hydro expansions come online. Electricity demand has grown sharply since 2014, reflecting modest population growth alongside rising fisheries, construction, and tourism activity. The Tasersiaq prefeasibility study points to a potential 700 to 1,000 MW export-scale hydropower resource over a longer horizon, which would if developed materially change Greenland’s position in the regional energy picture.
The wider energy mix tells a different story. Around four-fifths of total final energy consumption is met by imported petroleum products that arrive by tanker, with heating, fisheries, marine transport, and aviation all running primarily on imported fuel. Greenland sits outside both the EU framework and the IEA stockholding regime. Two further factors now shape Greenland’s position in Nordic energy security in ways that no other Nordic jurisdiction faces. The first is the geopolitical context: since late 2024, the second Trump administration has made explicit claims to Greenland, including statements declining to rule out economic or military coercion. The second is the critical minerals layer. The Tanbreez rare earth project was consolidated under US-listed Critical Metals Corp in 2025, with around USD 120 million in US Export-Import Bank financing interest. Greenland now sits inside the supply chain for some of the most strategically contested critical raw materials.
Key challenges
A maritime fuel chain operating in Arctic conditions. Greenland’s fuel supply depends on tanker deliveries into ports across an Arctic and sub-Arctic coast. Ice cover, narrow weather windows, and a thin ice-class shipping fleet all bind the delivery system, and there is no formal stockholding regime as a backup. Operational stocks are held privately with quantities not publicly disclosed.
Microgrids that cannot back each other up. The absence of a single connected grid means each settlement runs on its own equipment, and the loss of a single generator or hydropower plant has a localised but absolute effect on that community. Replacement parts and repair crews have to be flown or shipped in. The renewable buildout improves the long-run picture but does not change the topology caused by lack of interconnection.
Foreign and security policy under external pressure. The combination of strategic location, rare earth resources, and explicit external claims places the foreign and security policy axis of one of the eight Nordic jurisdictions under direct pressure from a treaty ally. Energy security in Greenland cannot now be separated from the wider strategic context.
