Beijing-based Bitcoin mining giant Bitmain has announced plans to construct one of the world’s largest data centers dedicated to cryptocurrency mining in the northwestern Chinese province of Xinjiang. The facility, capable of consuming up to 135 megawatts of power, is set to become the second-largest data center on the planet and could dramatically reshape the global Bitcoin mining landscape.
TL;DR
- Bitmain is building a massive data center near Karamay, Xinjiang, with a 135MW power capacity
- The facility will consist of 45 dust-free buildings with advanced cooling systems
- If fully equipped with AntMiner S9 units, the site could theoretically produce over 1,400 petahash per second
- Xinjiang was chosen for its cold, dry climate and access to government-supported renewable energy
- The project raises significant questions about Bitcoin mining centralization
A Mining Megaproject Takes Shape
Bitmain, the world’s leading producer of Bitcoin ASIC hardware, revealed on November 5 that construction is underway on a sprawling data center complex near the city of Karamay in Xinjiang, the largest administrative division in China. According to the company’s press release, the facility is specially designed for high-performance computing, with cryptocurrency mining — particularly Bitcoin — expected to be its primary application.
The scale of the project is staggering. With 45 dust-free buildings equipped with state-of-the-art cooling infrastructure, the data center will draw up to 135 megawatts of electricity. To put that in perspective, that is enough power to supply a small city. The facility would rank as the second most powerful data center globally by energy consumption, underscoring just how far industrial-scale Bitcoin mining has come from its hobbyist roots.
The Xinjiang Advantage: Climate and Cheap Power
According to Nishant Sharma, Bitmain’s international marketing manager, Xinjiang was selected for two critical advantages. First, the region’s bitterly cold and dry climate provides natural cooling for mining hardware — a significant operational cost saver when equipment runs 24 hours a day, seven days a week. Second, the province offers access to government-supported, low-cost wind and solar electricity, making energy expenses — typically the largest line item for mining operations — substantially more manageable.
“The government is supportive of new technologies that can develop the region’s economy and generate more employment opportunities,” Sharma noted, highlighting the local authorities’ willingness to attract blockchain infrastructure investment to the remote northwestern territory.
Hash Rate Implications
At current Bitcoin prices near $740, mining profitability is drawing increasing amounts of computing power to the network. The Bitcoin network’s total hash rate has been climbing steadily through late 2016, approaching the 2 exahash per second mark — a milestone that would have been unimaginable just a year earlier.
If the Xinjiang facility were entirely filled with Bitmain’s most advanced mining hardware, the AntMiner S9, calculations by Bitcoin Core and Blockstream developer Matt Corallo suggest the data center could theoretically produce over 1,400 petahash per second. That figure represents almost three-quarters of the estimated total hash rate currently securing the Bitcoin network. Such concentration of mining power in a single facility would be unprecedented.
Centralization Concerns Linger
However, Bitmain has pushed back against worst-case centralization fears. Sharma emphasized that Bitmain owns only “a very small share” of the data center, with the rest controlled by various investors whose intentions remain undisclosed. The company could not reveal the number of investors involved or their identities.
“We hope it will be used for various purposes that an efficient and powerful data center can be used for,” Sharma explained. “We do not know what percentage of investors would use it for mining bitcoin, altcoin — or for even mining at all. Frankly, I wouldn’t assume that the entire facility will be dedicated to bitcoin mining.”
Regardless of the final allocation, the Xinjiang project signals a clear trend: Bitcoin mining is becoming an increasingly industrialized, capital-intensive enterprise. Individual miners with a single machine in their garage are giving way to corporate-scale operations housed in purpose-built facilities consuming enough electricity to power towns. The era of industrial Bitcoin mining has arrived.
Why This Matters
The Xinjiang data center represents a pivotal moment in Bitcoin mining’s evolution from a distributed, grassroots activity to a centralized, industrial operation. While the facility promises efficiency gains through renewable energy and advanced cooling, the concentration of hash power raises legitimate concerns about network decentralization — a core principle of Bitcoin’s design. As mining difficulty continues to climb alongside the network hash rate, the barrier to entry for individual miners grows higher, potentially reshaping who participates in securing the Bitcoin network.

45 buildings full of s9s. wonder how many of those are still running or if they all got scrapped when difficulty adjusted
those S9s got dumped on ebay by the thousands when china banned mining in 2021. wonder how many ended up in texas and kazakhstan
a lot of those S9s went to inner mongolia farms first then got resold to texas and kazakhstan operators in 2022. i tracked about 40k units myself
40k units tracked is wild. i know guys in texas who bought pallets of decommissioned S9s in 2022 for parts alone. those machines are still circulating somehow
The 1400 PH/s estimate was theoretical. Real world hash rate depends on cooling, uptime, and chip quality. Still massive regardless.
xinjiang renewable energy is a stretch. most of it was coal fired. the pr spin was strong even back in 2016
karamay was chosen because electricity was basically free from government subsidized coal plants. the renewable narrative was pure greenwashing
Javier Ruiz subsidized coal was the entire thesis. karamay is literally built on oil and coal fields. bitmain went there for cheap electrons not sunshine
free electricity from subsidized coal is the real story. the greenwashing press releases were for investors not regulators
coal was the open secret. karamay sits next to some of the biggest coal fields in china. the pr about renewable energy was for western media
Wei C. theoretical is generous. those S9s were running at 14 TH/s each in ideal conditions. 45 buildings of them in xinjiang summer heat was probably 8-9 TH/s average
the cooling overhead alone in xinjiang summer would drop real hashrate well below theoretical. dust and heat are the silent hashrate killers
heat_sink_ 45 dust-free buildings in xinjiang summer is a joke. ambient hits 40C in karamay july. those S9s were running at 50% efficiency at best
dust free buildings is such a funny claim for xinjiang. have you been to karamay in spring. the sandstorms make dust-free impossible without serious HVAC which eats into your power budget
135MW is still insane for 2016. modern facilities are bigger but Bitmain was years ahead of everyone in scale
Bitmain controlling both hardware manufacturing AND massive mining facilities was the real centralization risk. hard to compete when the maker is also your biggest competitor
Bitmain building the hardware AND running the megafacility is like Nvidia operating every data center. the conflict of interest was baked in from day one
