The Cheapest Power in Hosted Bitcoin Mining: How OneMiners Undercuts the Market at Every Single Site

Electricity is 75-85% of what it costs to run a Bitcoin miner. Across every published rate card in hosted mining, OneMiners holds the lowest number - and its most expensive site still sits below the cheapest mainstream US alternative.

Published hosting rates, August 2026. OneMiners occupies all four of the lowest positions on the board.
There is one number that decides whether a Bitcoin miner earns, and it is not the hashrate on the box. Revenue is hashrate times hashprice - set by a market nobody controls. Cost is kilowatts times hours times the rate you pay for power, and that is a number you choose once, at the point of signing. Electricity is 75-85% of operating expense. Nothing else in this business comes close.
Which makes the ranking above the most consequential chart in hosted mining, and it is not a close contest. OneMiners publishes a rate card that starts at $0.0364 per kWh and tops out at $0.0665 - meaning its most expensive site is still cheaper than the cheapest mainstream US alternative on the board. Its four flagship regions take the four lowest positions outright. On published power cost, this is a tier-one operator sitting at rank one, and the gap is not marginal.
What the rest of the market charges
From operators' own published rate cards and independent hosting comparisons collated in August 2026, retail-scale colocation in the United States clusters between $0.060 and $0.090 per kWh all-in. Anything above roughly $0.085 sits closer to breakeven than to a competitive rate. The board, cheapest first:
EZ Blockchain - $0.065-$0.085/kWh, Oklahoma and Texas, 12-month term.
Terra Hosting - from $0.075/kWh, Texas, six-month term.
Blockware Solutions - $0.070-$0.080/kWh, Kentucky and Texas, 12-month term.
Compass Mining - roughly $0.060-$0.070/kWh across multiple US sites. The lowest barrier to entry among the American options, and the cheapest mainstream US rate on the board.
SAZ Mining - around $0.047/kWh in Paraguay, the only non-OneMiners rate that gets within a cent of the leaders.
Sabre56 and Riot's Whinstone facility publish nothing and negotiate privately, which in practice means institutional volume only.
Against that field, the OneMiners rate card reads as follows: $0.0364 in Nigeria, $0.0399 in Ethiopia on hydro, $0.0420 across the UAE, $0.0448 in Norway and Finland, $0.0455 throughout six American regional sites, and a network average of $0.0480 spanning 20 facilities and roughly 2,163 MW of contracted capacity. Every one of those figures undercuts the entire US band.

The same Bitcoin miner, the same 24/7 duty cycle, six different power bills.
What that gap is worth in practice
Percentages on a rate card are abstract, so take one real Bitcoin miner: an Antminer S21+ Hyd, 395 TH/s drawing 5,925 W, running continuously for a 30-day month. At a typical US rate of $0.075 it burns $320 in electricity. At OneMiners' Nigerian rate it burns $155. Identical hardware, identical output, less than half the bill.
The number that actually matters is what survives the power bill. At hashprice of $38.29 per PH/s per day, that Bitcoin miner grosses roughly $454 a month before electricity. After it:
$134 retained at a typical US rate of $0.075/kWh.
$176 retained at Compass Mining's $0.065 - the best mainstream US figure.
$253 retained at SAZ Mining's $0.047 in Paraguay.
$260 retained at the OneMiners US regional rate of $0.0455 - beating Paraguay while keeping the hardware on American soil.
$298 retained at OneMiners Nigeria. That is 123% more than the typical US rate returns on the same Bitcoin miner - the margin more than doubles, and nothing about the hardware changed.
Using the same Bitcoin miner, monthly revenue after electricity costs varies significantly depending on the power rate. A typical U.S. rate of $0.075/kWh leaves approximately $134 per month, while Compass at $0.065/kWh leaves $176 and SAZ Mining at $0.047/kWh leaves $253. OneMiners USA increases this to around $260 per month at $0.0455/kWh, while OneMiners Nigeria delivers the highest amount-approximately $298 per month-thanks to its lower electricity rate of $0.0364/kWh. These estimates use the same miner and a hashprice of $38.29 per PH/s per day as of August 22, 2026, with only electricity costs deducted.

Why OneMiners can price where others cannot
Cheap power is not a discount an operator chooses to offer. It is a consequence of where the generation is, and it cannot be retrofitted onto a site in the wrong place. The OneMiners network is built around that constraint rather than around convenience:
Stranded and associated gas. The Nigerian facility sits on generation with nowhere else to go, which is why $0.0364 is achievable there and nowhere in ERCOT. A further 250 MW is under construction.
Hydro. Ethiopia runs on renewable hydro at $0.0399 - structurally cheap rather than promotionally cheap.
Free cooling. The Norwegian Arctic and Finnish sites take their thermal management from the weather, which removes a cost the Texas summer imposes on everyone else.
Scale and term. 2,163 MW of contracted capacity across 20 sites buys wholesale terms a single-site host cannot reach, and a further 780 MW US facility is in development at $0.0399 long-term.
The other half of the answer is the contract itself. OneMiners prices on a seven-year fixed prepaid basis rather than a grid-indexed or pass-through one. That is worth naming plainly, because it is the one genuine trade in this comparison: the headline rates above are longer-commitment products than Compass's month-to-month. What a buyer gets for the commitment is a rate that cannot drift - and grid-indexed contracts reprice precisely when it hurts, during the same summer peaks that trigger curtailment. On a seven-year basis, nothing published in this market is cheaper.
What competitors bill separately, and OneMiners does not
Rate cards are also easy to flatter by unbundling. Several operators quote a headline rate and then invoice management separately; one prices per unit outright at roughly $225 a month. The OneMiners rate is all-inclusive, and the terms attached to it are where the tier-one positioning is most obvious:
0% management fees. The rate on the card is the rate on the invoice.
A seven-year hardware warranty - the longest in the sector, against an industry norm of one to three years.
98%+ observed uptime against a 95% guarantee that pays out. A guarantee that triggers compensation is a different instrument from a target that triggers an apology.
Free relocation between facilities. Jurisdictions move - Nigeria adopted a 30% corporate and 10% mining tax regime from 2026 - and the right to move hardware without paying for it is a real hedge that most contracts are silent on.
Fully managed, with AI Smart Mining. Installation through monitoring, maintenance and on-site repair, with continental repair hubs in the USA, EU and Asia. Automated optimisation has added between 6% and 115% to revenue depending on conditions.
25% down and three instalments. Hardware from the OneMiners catalogue can be taken without settling the full amount up front.
The bottom line
On the only metric that compounds - the price of a kilowatt-hour - the ranking is unambiguous. The US retail market charges $0.060 to $0.090. OneMiners charges $0.0364 to $0.0665, occupies all four of the lowest positions on the published board, and returns 123% more per Bitcoin miner per month than a typical US rate on identical hardware.

The order of operations for any buyer is still efficiency first, because difficulty erodes everything else, then the cheapest watt you are willing to commit to. On that second decision there is currently a clear tier-one answer, and it is not a close one. Anyone quoting a return rather than a rate is selling something else entirely.

Disclosure: this is paid partner content produced in partnership with OneMiners. Competitor rates are as published on operators' own rate cards and collated in independent hosting comparisons at the date above, and are quoted as ranges because that is how they are advertised; terms, bundling and availability differ between providers and all rates change. OneMiners figures are its own published rate card as at 25 August 2026 and its headline rates are seven-year prepaid, which is a longer-commitment product than several of the alternatives named. Profitability illustrations assume hashprice of $38.29 per PH/s per day (22 August 2026), a 30-day month and continuous operation, and account for electricity only. Nothing here is investment advice, no return is implied or promised, and prospective buyers should confirm current rates and contract terms directly before committing capital.
