Operational Growth and Hashrate Expansion
The steady rise in hashrate has been matched by consistent production gains. Bitdeer mined 196 BTC in May, then ramped up to 452 BTC in September as new rigs came online and additional megawatts were energized across its global sites, as detailed in the August and September 2025 updates.
The company’s proprietary mining fleet – all machines it owns and operates directly – is the main reason behind this acceleration. Unlike miners who lease or host rigs, Bitdeer’s strategy centers on full vertical control: it builds the machines, powers the sites, and runs the operations.
That approach gives it agility. Every EH/s added comes from new capacity Bitdeer actually controls, not third-party hardware.
If the trend holds, Bitdeer could cross the 40 EH/s mark by the end of Q4 – a pace of expansion that outperforms most listed competitors.
Infrastructure and Energy Efficiency
Behind the numbers sits one of the most ambitious energy footprints in Bitcoin mining. Bitdeer now operates more than 1.57 GW of online electrical capacity across seven sites in the U.S., Norway, and Bhutan – with another 1.4 GW under construction, according to its September report.
The Rockdale, Texas facility alone accounts for 563 MW and recently completed a 100 MW hydro-cooling conversion to boost thermal efficiency. In Norway, Bitdeer’s campuses tap into low-carbon hydro power and cold air for natural cooling. Bhutan, meanwhile, offers a rare combination of cheap hydroelectricity and stable climate – an ideal setup for dense mining clusters.
Across the portfolio, the company’s average energy cost hovers near $0.045 /kWh, giving it one of the lowest operating baselines in the public mining sector. That cost advantage becomes critical when difficulty climbs or Bitcoin prices soften.
Hardware Built In-House
A major reason Bitdeer can scale this quickly is that it doesn’t rely on other manufacturers. Its SEALMINER A3 series – officially launched in September 2025 – is designed, built, and deployed internally.
The top-end A3 Pro model delivers up to 660 TH/s at 12.5 J/TH, rivaling the Antminer S21 Pro. By manufacturing its own rigs, Bitdeer can upgrade faster and avoid the long lead times that slow down most miners. The company expects its overall fleet efficiency to drop from roughly 14 J/TH to 12.5 J/TH once the rollout is complete in early 2026.
Financial and Operational Metrics
At 35 EH/s and 14 J/TH, Bitdeer’s active fleet draws about 490 MW of power. At $0.045 per kWh, daily energy expense is roughly $530 000. With about 450 BTC mined each month and Bitcoin averaging ≈ $114 000 in September 2025, monthly self-mining revenue is ≈ $51 million.
Cooling improvements reduce power loss by around 8 % and extend rig lifespan by roughly 20 %, keeping breakeven below ≈ $40 000 per BTC – a level that leaves Bitdeer profitable even through moderate market pullbacks.
Financial Pulse
In its Q1 2025 financial report, Bitdeer posted $37.2 million in self-mining revenue and roughly 350 BTC produced that quarter.
While overall earnings dipped year-over-year following the halving, the mining division remained the company’s growth driver and has since accelerated as new capacity came online through mid-2025.
Technology Meets Sustainability
Bitdeer’s sites now resemble high-performance data centers more than traditional mining warehouses. The Rockdale hydro-cooling system, completed in July 2025, significantly improved uptime and power density. In Norway, hydroelectric power covers nearly all operations, supported by ambient cooling. In Bhutan, Bitdeer runs on a 99 % renewable grid.
This renewable mix and energy-efficiency design help Bitdeer manage regulatory scrutiny while aligning with ESG standards increasingly important to institutional investors.
Standing Among Giants
Marathon Digital runs around 31 EH/s, CleanSpark 22 EH/s, and IREN 15 EH/s. Bitdeer’s 35 EH/s – heading toward 40 EH/s – places it squarely among the top global miners by proprietary hashrate.
Its $0.045 /kWh energy cost further reinforces a competitive edge even against larger peers with higher overhead.
Forward Outlook and Strategic Direction
By late 2025, Bitdeer expects to finish deploying the A3 fleet and hit 40 EH/s. Through 2026, additional renewable capacity in Bhutan and Norway should push total hashrate to around 50 EH/s. An A4 ASIC, already in development, aims for sub-11 J/TH efficiency.
If power stays below $0.05 /kWh and efficiency improves to 12 J/TH, Bitdeer can remain profitable even if Bitcoin trades in the mid-$30 k range – a resilience few miners can claim.
