Speak of america shopping for Greenland has returned to Washington, and miners are monitoring the ability tasks on the island.
The White Home stated a U.S. buy of Greenland is an “energetic dialogue,” in response to 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 response to 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 response to 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 means 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 way smaller than the tendered ambition.
Nukissiorfiit stories about 91.3 megawatts of hydropower capability throughout its programs and a mean electrical energy gross sales worth of about DKK 1.81 per kilowatt-hour in 2024, in response to its annual report.
Retail-style pricing at that degree doesn’t map cleanly onto mining economics.
That’s the reason any massive construct relies on industrial energy buy agreements or behind-the-meter provide at new era, moderately than shopping for energy like a standard buyer.
The dearth of a nationwide grid narrows the paths to scale.
Energy stations typically serve cities and settlements as native programs, with restricted interconnection, in response to Entice Greenland.
That pushes early “stranded” or surplus-energy ideas towards colocating versatile load at particular crops.
Greenland reporting has mentioned using surplus vitality within the context of reducing vitality prices, in response to Greenland Overview.
If 5–25 megawatts could be aggregated behind the meter close to present era, 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 following rung up is Nuuk’s principal hydro plant.
Scaling bitcoin mining in Greenland: from surplus energy pilots to grid-level enlargement
Buksefjord is deliberate to broaden from 45 megawatts to 121 megawatts, with development anticipated to start in 2026 and commissioning focused for 2032, in response to NunaGreen.
The European Funding Financial institution’s undertaking pipeline references a roughly 76-megawatt Buksefjord-3 construct close to the prevailing 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 totally utilized.
That means 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 response to minerstat.
On that baseline, a totally utilized 1.08 GW mine implies about 4–6% of as we speak’s community hashrate, with the share shrinking if world hashrate expands.
May Trump-linked capital eye Greenland’s vitality surplus for Bitcoin mining enlargement?
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 response to 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 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 development timelines cleared.
Even in a “what if” sovereignty state of affairs, the constraints keep sensible.
Industrial hydro requires multiyear development, heavy logistics, and long-duration offtake, and mines want resilient knowledge hyperlinks, spares, and import capability for ASIC fleets.
Greenland Join hyperlinks Canada, Nuuk, Qaqortoq, and Iceland by subsea cable, in response to Tusass, but it surely doesn’t resolve transmission to distant hydro basins.
Clear, agency megawatts additionally face competitors from different masses.
The Worldwide Power Company has warned that AI will drive increased electrical energy demand from knowledge 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 response to 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 vitality economics and geopolitics matter for large-scale Bitcoin mining
Nonetheless, if Greenland have been introduced beneath U.S. jurisdiction and handled as an vitality buildout zone moderately than a small, fragmented utility market, the renewable ceiling that issues for mining would shift from 1-GW-class hydro tenders to additionally concentrate on wind.
In keeping with a programs research printed 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 idea that 20% of Greenland’s ice-free space is out there.
That equates to about 170 GW of common era on an vitality 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 could be pushed in concept.
At 15–22 J/TH with PUE round 1.1, 170 GW of common era implies roughly 7.0–10.4 ZH/s of hashing capability if miners might soak up the typical output as a versatile load, properly above as we speak’s community.
Present hashrate stands at round 1 ZH/s, so buying sufficient mining machines to facilitate such a build-out makes this largely a theoretical train in potential forward-facing limits.
Additionally, 10 ZH/s shouldn’t be a “24/7 agency baseload” except you add large transmission, overbuild, curtailment, and storage/firming (or settle for downtime/variable operation). It’s a ceiling based mostly on absorbing common wind vitality moderately than delivering assured energy each hour.
Nonetheless, a crude linear extrapolation of that very same research’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 moderately than a construct plan, given siting, allowing, ports, roads, and HVDC necessities.
In keeping 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 thousands and thousands of items.
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 instances over. Or round $55 billion to equal the present community hashrate (it isn’t merely 1/tenth attributable to scaling).
These are all “again of an envelope” figures with plenty of caveats and assumptions, however the actuality is that there is sufficient unused vitality in Greenland to energy the Bitcoin community many instances over. With Starlink deployment, you can in all probability construct some main AI datacenters, too.
