Speak of the USA shopping for Greenland has returned to Washington, and miners are monitoring the ability initiatives on the island.
The White Home stated a U.S. buy of Greenland is an “lively dialogue,” in line with Reuters.
For Bitcoin miners, the extra actionable clock is Greenland’s industrial energy planning.
How Greenland’s hydropower interprets into actual Bitcoin mining capability
Greenland’s authorities stated it plans to open a public tender spherical within the second half of 2026 for the 2 largest mapped hydropower websites meant for industrial use, Tasersiaq (web site 07.e) and Tarsartuup Tasersua (web site 06.g), in line with Naalakkersuisut.gl.
It stated the 2 websites collectively might produce greater than 9,500 gigawatt-hours yearly.
Mining math is easy.
Bitmain’s Antminer S21 specification lists 200 TH/s at 3,500 watts, or about 17.5 joules per terahash, in line with Bitmain.
Utilizing a planning energy utilization effectiveness worth close to 1.1 (cooling and overhead), 1 megawatt of facility energy equates to about 0.052 exahash per second (EH/s) at 17.5 J/TH.
That suggests about 0.041–0.061 EH/s throughout a 15–22 J/TH effectivity band.
| Facility energy (MW) | Hashrate ceiling (EH/s) @ 17.5 J/TH, PUE 1.1 |
|---|---|
| 5 | 0.26 |
| 25 | 1.30 |
| 50 | 2.60 |
| 100 | 5.19 |
Greenland’s put in base is much smaller than the tendered ambition.
Nukissiorfiit experiences about 91.3 megawatts of hydropower capability throughout its programs and a median electrical energy gross sales value of about DKK 1.81 per kilowatt-hour in 2024, in line with its annual report.
Retail-style pricing at that degree doesn’t map cleanly onto mining economics.
That’s the reason any giant construct depends upon industrial energy buy agreements or behind-the-meter provide at new technology, slightly than shopping for energy like a standard buyer.
The shortage of a nationwide grid narrows the paths to scale.
Energy stations typically serve cities and settlements as native programs, with restricted interconnection, in line with Lure Greenland.
That pushes early “stranded” or surplus-energy ideas towards colocating versatile load at particular vegetation.
Greenland reporting has mentioned using surplus power within the context of reducing power prices, in line with Greenland Evaluation.
If 5–25 megawatts will be aggregated behind the meter close to current technology, the ceiling is about 0.21–1.52 EH/s throughout the 15–22 J/TH band (about 0.26–1.30 EH/s at 17.5 J/TH).
That’s sufficient for pilots, however not sufficient to maneuver world community share.
The subsequent rung up is Nuuk’s principal hydro plant.
Scaling bitcoin mining in Greenland: from surplus energy pilots to grid-level growth
Buksefjord is deliberate to develop from 45 megawatts to 121 megawatts, with building anticipated to start in 2026 and commissioning focused for 2032, in line with NunaGreen.
The European Funding Financial institution’s undertaking pipeline references a roughly 76-megawatt Buksefjord-3 construct close to the present 45-megawatt plant.
If 50–121 megawatts of output have been contracted to miners, {the electrical} ceiling is about 2.07–7.33 EH/s throughout the 15–22 J/TH band (about 2.6–6.3 EH/s at 17.5 J/TH).
That assumes these megawatts are usually not absorbed by Nuuk demand development and electrification plans.
The 2-site tender is the place Greenland turns into a gigawatt-scale dialogue.
Greater than 9,500 GWh a yr equates to about 1.08 gigawatts of common energy if absolutely utilized.
That suggests an electricity-limited hashrate ceiling round 44.8–65.7 EH/s throughout the 15–22 J/TH band (about 56.0 EH/s at 17.5 J/TH).
Monitoring websites place Bitcoin hashrate round 1.03–1.17 zetahash per second (ZH/s), and minerstat locations issue close to 148 trillion, in line with minerstat.
On that baseline, a totally utilized 1.08 GW mine implies about 4–6% of right now’s community hashrate, with the share shrinking if world hashrate expands.
Might Trump-linked capital eye Greenland’s power surplus for Bitcoin mining growth?
Trump-linked mining capital is already forming, which is why Greenland’s energy calendar might draw consideration contained in the sector.
Hut 8 partnered with Eric Trump to launch American Bitcoin, combining Hut 8’s mining operations with an investor group that features Donald Trump Jr., whereas Hut 8 retained an 80% stake.
American Bitcoin stated put in hashrate expanded to about 24 EH/s and cited fleet effectivity round 16.4 J/TH as of Sept. 1, 2025, in line 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).
Meaning a totally utilized 1.08 GW tender buildout might energy an American Bitcoin-sized fleet greater than as soon as over, if the offtake have been devoted to mining and if transmission and building timelines cleared.
Even in a “what if” sovereignty state of affairs, the constraints keep sensible.
Industrial hydro requires multiyear building, heavy logistics, and long-duration offtake, and mines want resilient information hyperlinks, spares, and import capability for ASIC fleets.
Greenland Join hyperlinks Canada, Nuuk, Qaqortoq, and Iceland by subsea cable, in line with Tusass, but it surely doesn’t remedy transmission to distant hydro basins.
Clear, agency megawatts additionally face competitors from different hundreds.
The Worldwide Power Company has warned that AI will drive larger electrical energy demand from information facilities, which might increase the chance value of dedicating long-duration renewable output to mining.
Diplomacy will form financing situations round any “Trump Greenland mine” thesis.
European officers have burdened that Greenland’s standing rests on consent and sovereignty norms, in line with Reuters.
Greenland’s tender spherical deliberate for the second half of 2026 will set the baseline for any large-scale Bitcoin mining offtake from new hydropower on the island.
Why Greenland’s power economics and geopolitics matter for large-scale Bitcoin mining
Nonetheless, if Greenland have been introduced beneath U.S. jurisdiction and handled as an power buildout zone slightly than a small, fragmented utility market, the renewable ceiling that issues for mining would shift from 1-GW-class hydro tenders to additionally deal with wind.
In accordance with a programs examine revealed in Power and listed on ScienceDirect, Greenland’s onshore wind technical potential is about 333 GW nameplate, producing about 1,487 TWh per yr beneath the belief that 20% of Greenland’s ice-free space is out there.
That equates to about 170 GW of common technology on an power foundation.
Output can be variable and would require transmission, overbuild, curtailment, storage, and firming to serve a 24/7 load at scale.
Translating that energy-only ceiling into hashrate reveals how far the “Trump Greenland mine” narrative will be pushed in principle.
At 15–22 J/TH with PUE round 1.1, 170 GW of common technology implies roughly 7.0–10.4 ZH/s of hashing capability if miners might take up the common output as a versatile load, properly above right now’s community.
Present hashrate stands at round 1 ZH/s, so buying sufficient mining machines to facilitate such a build-out makes this principally a theoretical train in potential forward-facing limits.
Additionally, 10 ZH/s isn’t a “24/7 agency baseload” until you add huge transmission, overbuild, curtailment, and storage/firming (or settle for downtime/variable operation). It’s a ceiling based mostly on absorbing common wind power slightly than delivering assured energy each hour.
Nonetheless, a crude linear extrapolation of that very same examine’s land-availability assumption from 20% to 100% implies about 7,435 TWh per yr (about 848 GW common), or roughly 34.8–51.7 ZH/s.
That may be a physics-and-maps ceiling slightly than a construct plan, given siting, allowing, ports, roads, and HVDC necessities.
In accordance with IRENA, the worldwide common put in value for brand spanking new onshore wind in 2023 was about $1,154 per kW.
That places 333 GW at roughly $384 billion in generators alone earlier than Arctic premiums, transmission, and firming infrastructure.
OneMiners lists an Antminer S21 XP Hyd at 473 TH/s for $6,799. To make the most of 333 GW, you’d want roughly 21,141,650 miners, which involves round $143 billion.
Nonetheless, that’s simply the ASIC buy value. It excludes delivery, duties/VAT, spares, racks/PSUs/networking, buildings, cooling/hydro loops, and commissioning, stuff that’s very non-trivial at tens of tens of millions of models.
All in, assuming {hardware} is out there (which it is not), an funding of round $427 billion would give a miner based mostly in Greenland sufficient renewable energy-sourced hash energy to regulate the $1.8 trillion Bitcoin community ten occasions over. Or round $55 billion to equal the present community hashrate (it is not merely 1/tenth attributable to scaling).
These are all “again of an envelope” figures with a number of caveats and assumptions, however the actuality is that there is sufficient unused power in Greenland to energy the Bitcoin community many occasions over. With Starlink deployment, you can in all probability construct some main AI datacenters, too.
