Rumors that america will purchase Greenland have returned to Washington, and miners are following power initiatives on the island.
The White Home stated the US buy of Greenland is an “energetic dialogue,” in accordance with Reuters.
For Bitcoin miners, essentially the most viable watch is Greenland’s industrial power planning.
How Greenland Hydropower Interprets into Actual Bitcoin Mining Capability
The Greenland authorities stated it plans to open a public bidding spherical within the second half of 2026 for the 2 largest mapped hydropower websites supposed for industrial use, Tasersiaq (website 07.e) and Tarsartuup Tasersua (website 06.g), in accordance with Naalakkersuisut.gl.
He stated the 2 websites collectively may produce greater than 9,500 gigawatt-hours a 12 months.
Mining arithmetic is straightforward.
Bitmain’s Antminer S21 specification lists 200 TH/s at 3,500 watts, or about 17.5 joules per terahash, in accordance with Bitmain.
Utilizing a planning power use effectiveness worth near 1.1 (cooling and overhead), 1 megawatt of facility power is roughly equal to 0.052 exahash per second (EH/s) at 17.5 J/TH.
This means about 0.041 to 0.061 EH/s in an effectivity band of 15 to 22 J/TH.
Greenland’s put in base is far smaller than the proposed ambition.
Nukissiorfiit stories round 91.3 megawatts of hydroelectric capability throughout its methods and a median electrical energy gross sales value of round 1.81 Danish crowns per kilowatt-hour in 2024, in accordance with its annual report.
Retail costs at that stage don’t clearly correspond to the mining economics.
That is why any main building depends on industrial energy buy agreements or new technology behind-the-meter provide, relatively than buying energy like a traditional buyer.
The shortage of a nationwide community narrows the paths to scale.
In keeping with Entice Greenland, energy crops usually serve cities and settlements as native methods, with restricted interconnection.
That drives early ideas of “stranded” or surplus power towards putting versatile masses at particular crops.
Experiences from Greenland have mentioned using surplus power within the context of lowering power prices, in accordance with Greenland Assessment.
If 5 to 25 megawatts might be added behind the meter close to current technology, the ceiling is about 0.21 to 1.52 EH/s within the 15 to 22 J/TH band (about 0.26 to 1.30 EH/s at 17.5 J/TH).
That is sufficient for pilots, however not sufficient to extend world community participation.
The following step is the primary hydroelectric energy station in Nuuk.
Increasing bitcoin mining in Greenland: from surplus power pilots to network-level growth
Buksefjord is deliberate to be expanded from 45 megawatts to 121 megawatts, with building anticipated to start in 2026 and commissioning deliberate for 2032, in accordance with NunaGreen.
The European Funding Financial institution’s challenge portfolio refers back to the building of the roughly 76 megawatt Buksefjord-3 close to the present 45 megawatt plant.
If between 50 and 121 megawatts of manufacturing had been contracted to miners, {the electrical} ceiling can be roughly 2.07 to 7.33 EH/s within the 15 to 22 J/TH band (round 2.6 to six.3 EH/s to 17.5 J/TH).
That signifies that these megawatts will not be absorbed by Nuuk’s electrification and demand development plans.
The bidding for 2 websites is the place Greenland turns into a gigawatt-scale debate.
Greater than 9,500 GWh per 12 months is equal to roughly 1.08 gigawatts of common energy if totally used.
That suggests an electrically restricted hash price ceiling of round 44.8 to 65.7 EH/s within the 15 to 22 J/TH band (round 56.0 EH/s to 17.5 J/TH).
Monitoring websites put Bitcoin’s hash price between 1.03 and 1.17 zetahash per second (ZH/s), and Minerstat places the problem close to 148 trillion, in accordance with Minerstat.
On that baseline, a completely utilized 1.08 GW mine includes round 4% to six% of the present community hashrate, and the proportion will scale back if the worldwide hashrate expands.
Might Trump-linked capital benefit from Greenland’s power surplus for the growth of Bitcoin mining?
Trump-linked mining capital is already forming, which is why Greenland’s power calendar may draw consideration throughout the sector.
Hut 8 partnered with Eric Trump to launch American Bitcoin, combining Hut 8’s mining operations with an funding group that features Donald Trump Jr., whereas Hut 8 retained an 80% stake.
American Bitcoin stated the put in hash price expanded to roughly 24 EH/s and cited fleet effectivity round 16.4 J/TH as of September 1, 2025, in accordance with the corporate.
Utilizing the identical PUE 1.1 planning worth, 24 EH/s implies roughly 430 megawatts of facility energy at 16.4 J/TH (about 460 megawatts at 17.5 J/TH).
Which means a completely utilized 1.08 GW tender may energy a US fleet the scale of Bitcoin greater than as soon as, if extraction had been devoted to mining and if transmission and building timelines had been clarified.
Even in a “what-if” sovereignty situation, limitations stay sensible.
Industrial hydro requires multi-year building, heavy logistics and long-duration provide, and mines want sturdy knowledge hyperlinks, spare elements and import functionality for ASIC fleets.
Greenland Join hyperlinks Canada, Nuuk, Qaqortoq and Iceland by way of an undersea cable, in accordance with Tusass, however doesn’t tackle transmission to distant hydroelectric basins.
Clear, regular megawatts additionally face competitors from different masses.
The Worldwide Power Company has warned that AI will drive better demand for electrical energy from knowledge centres, which can improve the chance price of dedicating long-duration renewable manufacturing to mining.
Diplomacy will form the financing circumstances round any “Trump mines Greenland” thesis.
European officers have emphasised that Greenland’s standing relies on consent and sovereignty guidelines, in accordance with Reuters.
The Greenland bidding spherical scheduled for the second half of 2026 will set the inspiration for any large-scale Bitcoin mining from new hydropower on the island.
Why Greenland’s Power Financial system and Geopolitics Matter for Giant-Scale Bitcoin Mining
Nevertheless, if Greenland had been to come back underneath US jurisdiction and be handled as an power growth zone relatively than a small, fragmented utility market, the ceiling on renewable power imports for mining would shift from 1 GW hydropower tenders to additionally specializing in wind energy.
In keeping with a methods research printed in Power and listed on ScienceDirect, Greenland’s technical onshore wind potential is roughly 333 nominal GW, producing round 1,487 TWh per 12 months underneath the belief that 20% of Greenland’s ice-free space is out there.
That’s equal to about 170 GW of common technology in power phrases.
Manufacturing can be variable and would require transmission, overbuilding, discount, storage and reinforcement to serve a 24/7 load at scale.
Translating that power restrict solely into hashrate reveals how far the “Trump Greenland mine” narrative might be pushed in concept.
At 15-22 J/TH with PUE round 1.1, 170 GW of common technology implies about 7.0-10.4 ZH/s of hash capability if miners may take up the common output as a versatile load, nicely above the present grid.
The present hash price is round 1 ZH/s, so buying sufficient mining machines to facilitate such a construct makes this primarily a theoretical train on potential limits going ahead.
Additionally, 10 ZH/s is just not a “agency 24/7 baseload” except you add bulk transmission, overbuild, discount and storage/firming (or settle for variable downtime/operation). It’s a roof primarily based on absorbing common wind power relatively than delivering assured power each hour.
Nonetheless, a crude linear extrapolation of the identical research’s land availability assumption from 20% to 100% implies about 7,435 TWh per 12 months (about 848 GW on common), or about 34.8-51.7 ZH/s.
This can be a physics and map boundary relatively than a building plan, bearing in mind location, allowing, port, highway and HVDC necessities.
In keeping with IRENA, the worldwide common set up price of recent onshore wind energy in 2023 was about $1,154 per kW.
That places 333 GW at about $384 billion in generators alone earlier than bonuses, transmission and strengthening Arctic infrastructure.
OneMiners lists an Antminer S21 XP Hyd at 473 TH/s for $6,799. To make use of 333 GW, roughly 21,141,650 miners can be wanted, which is equal to about $143 billion.
Nevertheless, that’s solely the acquisition price of the ASIC. Excludes transport, tariffs/VAT, spare elements, racks/PSU/networking, buildings, cooling/hydro circuits and commissioning, issues that aren’t trivial in tens of thousands and thousands of models.
In complete, assuming {hardware} is out there (which it is not), an funding of round $427 billion would give a Greenland-based miner sufficient hash energy from renewable power to regulate the $1.8 trillion Bitcoin community tenfold. Or about $55 billion to match the community’s present hashrate (it is not merely a tenth on account of scale).
These are all “backwards” figures with many caveats and assumptions, however the actuality is that there’s sufficient unused power in Greenland to energy the Bitcoin community many instances over. With the implementation of Starlink, some main AI knowledge facilities may most likely be constructed as nicely.
