Discuss of the US shopping for Greenland is returning to Washington, and miners are pursuing energy tasks on the island.
In response to Reuters, the White Home mentioned the US buy of Greenland was “actively mentioned.”
A extra sensible look ahead to Bitcoin miners is Greenland's industrial energy challenge.
How Greenland's hydropower interprets into precise Bitcoin mining capability
In response to Naalakkersuuisut.gl, the Authorities of Greenland has introduced that it plans to open a public tender within the second half of 2026 for the 2 largest hydropower vegetation for mapped industrial use, Tasselsiak (website 07.e) and Tarsaltuap Tasselsua (website 06.g).
Collectively, the 2 websites will be capable of generate greater than 9,500 gigawatt hours of electrical energy yearly.
Mining calculations are simple.
In response to Bitmain, Bitmain's Antminer S21 specs listing 200 TH/s at 3,500 watts, or roughly 17.5 joules per terahash.
Utilizing a deliberate energy effectivity worth (cooling and overhead) near 1.1, 1 megawatt of facility energy is equal to roughly 0.052 exahash/second (EH/s) at 17.5 J/TH.
This implies roughly 0.041 to 0.061 EH/s throughout the 15 to 22 J/TH effectivity band.
Greenland's put in base is way smaller than the bid's ambitions.
Nukissiorfiit's annual report studies that the corporate's whole system hydropower capability is roughly 91.3 MW, with a median electrical energy gross sales worth of roughly DKK 1.81 per kilowatt hour in 2024.
Retail-style pricing at that degree clearly doesn’t correspond to the economics of the mining business.
Massive constructions subsequently depend on industrial energy buy agreements or new-generation behind-the-meter provides, moderately than buying energy like common prospects.
The dearth of a nationwide energy grid narrows the trail to scale.
In response to Trapp Greenland, energy vegetation sometimes serve cities and settlements as native techniques with restricted interconnections.
This pushes the sooner idea of “stranded” or surplus power in direction of coexisting versatile masses in a given plant.
In response to Greenland Overview, Greenland's report discusses using surplus power with a view to lowering power prices.
For those who can mixture 5 to 25 megawatts behind the meter close to your present generator, the higher restrict can be roughly 0.21 to 1.52 EH/s throughout the 15 to 22 J/TH band (roughly 0.26 to 1.30 EH/s at 17.5 J/TH).
That is ok for pilots, however not sufficient to drive world community share.
The following tier is Nuuk's important hydroelectric energy station.
Increasing Bitcoin mining in Greenland: From surplus energy testing to grid-level enlargement
Buxefjord is deliberate to increase from 45 MW to 121 MW, with development beginning in 2026 and commissioning focused for 2032, Nunagreen mentioned.
The European Funding Financial institution's challenge pipeline refers back to the development of roughly 76 MW of Buxefjord-3, positioned near an present 45 MW energy plant.
If an output of fifty to 121 MW is contracted to the miner, {the electrical} cap can be roughly 2.07 to 7.33 EH/s throughout the 15 to 22 J/TH band (roughly 2.6 to six.3 EH/s at 17.5 J/TH).
This assumes that these megawatts are usually not absorbed by Nuuk's demand development and electrification plans.
Two bids put Greenland within the dialogue for gigawatts.
Greater than 9,500 GWh per yr equates to roughly 1.08 gigawatts of common energy when totally utilized.
Which means that the power-limited hashrate is capped at roughly 44.8-65.7 EH/s throughout the 15-22 J/TH band (roughly 56.0 EH/s at 17.5 J/TH).
In response to minerstat, the monitoring website estimates Bitcoin's hash price to be round 1.03 to 1.17 zetahashes per second (ZH/s), and minerstat's problem degree is near 148 trillion.
On this baseline, a completely utilized 1.08 GW mine would symbolize roughly 4-6% of at present's community hash price, a share that shrinks as the worldwide hash price grows.
May capital related to President Trump look to Greenland's surplus power to increase Bitcoin mining?
Mining capitals linked to President Trump have already been fashioned, which is why Greenland's energy calendar is attracting consideration inside the sector.
Hut 8 partnered with Eric Trump to launch American Bitcoin, combining Hut 8's mining operations with a bunch of buyers that included Donald Trump Jr., however Hut 8 retained an 80% stake.
In response to the corporate, American Bitcoin mentioned that as of September 1, 2025, the put in hashrate has expanded to roughly 24 EH/s and the fleet effectivity is roughly 16.4 J/TH.
Utilizing the identical PUE 1.1 deliberate worth, 24 EH/s means roughly 430 MW of facility energy at 16.4 J/TH (roughly 460 MW at 17.5 J/TH).
Which means that if the offtake is devoted to mining and transmission and development schedules are clear, the 1.08 GW of bid gear may doubtlessly energy a Bitcoin-sized fleet in the USA a number of instances if totally utilized.
Even in a “what if” sovereignty situation, the constraints stay practical.
Industrial hydropower requires multi-year development, important logistics, and long-term water withdrawals, and mines require resilient knowledge hyperlinks, spare components, and the power to import ASIC fleets.
Tasas mentioned Greenland Join connects Canada, Nuuk, Qakortok and Iceland with an undersea cable, however transmission to distant hydro basins shouldn’t be resolved.
Clear, steady megawatts additionally face competitors from different masses.
The Worldwide Power Company has warned that AI may enhance demand for electrical energy from knowledge facilities, elevating the chance value of dedicating long-term renewable power output to mining.
Diplomacy will form funding situations primarily based on the “Trump Greenland Mine” argument.
In response to Reuters, European officers burdened that Greenland's standing relies on consent and sovereignty norms.
Greenland's bidding spherical, scheduled for late 2026, will set the baseline for large-scale Bitcoin mining from new hydropower on the island.
Why Greenland's power financial system and geopolitics matter for large-scale Bitcoin mining
Nonetheless, if Greenland had been to return beneath US jurisdiction and be handled as an power enhancement zone moderately than a small, fragmented energy market, the renewable power cap necessary for mining would shift from 1GW-class hydropower tenders to a give attention to wind as effectively.
In response to a techniques examine revealed in power The technical potential of Greenland's onshore wind energy, as listed by ScienceDirect, is roughly 333 GW, which might generate roughly 1,487 TWh per yr, assuming 20% of Greenland's ice-free space is offered.
This corresponds to a median energy technology of roughly 170 GW on an power foundation.
Manufacturing volumes fluctuate, requiring transmission, overbuilding, discount, storage, and fixing to accommodate giant masses 24/7.
Changing this energy-only cap to hashrate exhibits how far the “Trump Greenland Mine” narrative can theoretically be pushed.
At 15-22 J/TH with a PUE of round 1.1, if the miners had been in a position to soak up the common output as a versatile load, the common energy technology of 170 GW would imply a hashing capability of round 7.0-10.4 ZH/s, which is considerably greater than at present's networks.
With the present hashrate round 1 ZH/s, buying sufficient mining machines to facilitate such a construct would primarily be a theoretical train of potential forward-looking limitations.
Additionally, 10 ZH/s shouldn’t be a “24/7 steady baseload” except you add giant sends, overbuilds, reductions, storage/fixing (or settle for downtime/fluctuating operations). It is a ceiling primarily based on common wind power absorption, moderately than offering assured energy each hour.
But, a tough linear extrapolation of the identical examine's land availability assumptions from 20% to 100% would suggest roughly 7,435 TWh (common roughly 848 GW) per yr, or roughly 34.8 to 51.7 ZH/s.
It is a cap primarily based on physics and mapping, not a development plan that takes under consideration siting, allowing, ports, roads, and HVDC necessities.
In response to IRENA, the worldwide common put in value for brand new onshore wind energy in 2023 was roughly $1,154 per kW.
This leaves 333 GW of generators alone value about $384 billion, excluding insurance coverage, transmission, and infrastructure within the Arctic.
OneMiners is itemizing the Antminer S21 XP Hyd at 473 TH/s for $6,799. To make the most of 333 GW, roughly 21,141,650 miners can be required, which might be roughly $143 billion.
Nonetheless, that is simply the price of buying the ASIC. This doesn’t embody all-important prices corresponding to transportation, customs/VAT, spares, racks/PSUs/networks, buildings, cooling/hydro loops, commissioning, and so on., which might run into the tens of thousands and thousands of models.
All instructed, an funding of about $427 billion would give the Greenland-based miner sufficient renewable energy-derived hashing energy to manage the $1.8 trillion Bitcoin community by greater than 10 instances, assuming the {hardware} is offered (which it isn't). Or about $55 billion equal to at present's community hash price (not merely 1/tenth, attributable to scaling).
These are all “again of the envelope” numbers 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 Starlink, you could possibly most likely construct a significant AI knowledge heart as effectively.
