A number of US-based Bitcoin (BTC) mining swimming pools have curtailed operations in response to excessive winter climate that strained electrical energy grids throughout the nation.
The reductions got here as an Arctic chilly snap introduced subfreezing temperatures throughout massive elements of the USA.
Arctic Climate Triggers Sharp Bitcoin Hashrate Pullback
In keeping with TheMinerMag, 2 main Bitcoin mining swimming pools serving North America collectively minimize over 110 exahashes per second (EH/s) of hashrate in late January 2026.
Foundry USA, the world’s largest Bitcoin mining pool, noticed a pointy drop in hashrate. It fell from almost 340 EH/s to round 242 EH/s late final week.
Luxor additionally recorded a decline, with its hashrate sliding from roughly 45 EH/s to 26 EH/s. Smaller pullbacks have been noticed at Antpool and Binance Pool as properly. These figures have since fallen additional.
“Bitcoin hashrate on FoundryUSA alone is down by almost 200 EH/s, or 60%, since Friday amid continued curtailment. Short-term block manufacturing has slowed right down to 12 minutes,” TheMinerMag wrote.
Knowledge from the Hashrate Index exhibits that Foundry nonetheless controls roughly 163.5 EH/s of hashing energy. It accounts for about 22.59% of the entire Bitcoin community hashrate. Luxor’s share stands at 3.01%, with its hashrate falling to roughly 21.9 EH/s.

The widespread decline in hashrate coincides with a extreme Arctic freeze that has introduced snow, ice, and excessive chilly, sharply growing heating demand. Energy grids in a number of states got here beneath pressure, prompting operators to problem conservation requests.
In keeping with the BBC, the winter storm has left not less than three folks lifeless and knocked out energy to a whole lot of 1000’s of properties. Faculties and roads have been closed nationwide, and flights have been canceled as “life-threatening” circumstances stretched from Texas to New England.
In a publish on X (previously Twitter), Matthew Sigel, Head of digital belongings analysis at VanEck, pointed to the function Bitcoin miners can play in easing grid pressure throughout excessive climate occasions.
“Tragic that 1M+ Individuals are with out energy as a result of winter storm impacting the japanese US. Some public bitcoin miners have significant capability in or close to affected areas, and a number of other resembling CLSK, RIOT, BTDR and others are structurally set as much as act as versatile masses through utility demand response applications, together with the Tennessee Valley Authority (TVA). We don’t but have affirmation of actual time curtailments for this storm, however the mannequin has already confirmed its worth when circumstances tighten,” he wrote.
On account of excessive winter storms within the U.S., a number of mining farms throughout the nation have skilled energy outages. Bitcoin’s whole hashrate dropped by roughly 30% in a brief interval, a lower of about 260 EH/s. Roughly 1.3 million mining rigs have been shut down as they… pic.twitter.com/75DniLUDh8

The hashrate downturn additionally comes amid a sustained drawdown in miner reserves. In keeping with CryptoQuant information, Bitcoin miner holdings fell to their lowest stage since 2010 in January 2026, highlighting the mounting monetary strain throughout the sector.
Subdued Bitcoin costs and rising power prices are squeezing margins, pushing many miners towards unprofitable territory. In response, some operators are reassessing their enterprise fashions. Bitfarms, for instance, has begun reallocating assets towards synthetic intelligence and high-performance computing.
In the meantime, the broader outlook for miners stays difficult. Electrical energy costs reached a report 18.07 cents per kilowatt-hour in September 2025, up 10.5% since January.
BeInCrypto reported an emergency energy public sale plan from President Trump’s administration, set so as to add $15 billion in new technology by means of tech-backed, long-term contracts.
The plan could provide long-term reduction as new capability comes on-line, although the advantages will take time to materialize. Within the interim, miners should concentrate on inexpensive entry to energy and lively participation in demand response to outlive.
