Bitcoin Hashrate Drops to Seven-Month Low as US Winter Storm Disrupts Mining

Bitcoin’s network hashrate fell to its lowest level in seven months over the weekend as a powerful winter storm swept across the United States, forcing miners to scale back operations amid surging energy demand and widespread power disruptions.

According to AccuWeather, the massive storm system impacted more than three dozen US states, bringing heavy snow, ice and freezing temperatures that left around one million customers without power.

The extreme conditions placed additional strain on regional electricity grids, prompting some Bitcoin miners to curtail activity to help stabilize supply.

Bitcoin Hashrate Slides More Than 40% Over Weekend Before Rebounding

Data from mining analytics platform CoinWarz shows that Bitcoin’s hashrate began sliding on Friday before plunging sharply over the weekend.

By Sunday, the network’s computing power had dropped to roughly 663 exahashes per second (EH/s), representing a decline of more than 40% in just two days.

The hashrate has since rebounded, climbing back to around 854 EH/s as of Monday.

Oregon-based miner Abundant Mines said the scale of the disruption was significant.

“Approximately 40% of global Bitcoin mining capacity has gone offline in the past 24 hours due to extreme winter weather,” the company said, adding that many operators voluntarily reduced output as energy demand spiked.

The firm described this responsiveness as a structural advantage of Bitcoin mining, noting that operations can shut down quickly during grid stress and restart once conditions normalize.

The US accounts for the largest share of global Bitcoin mining activity.

Estimates from the Hashrate Index suggest the country contributes nearly 38% of the network’s total hashrate, while a 2024 report from the Energy Information Administration identified at least 137 crypto-mining facilities nationwide.

Industry advocates argue that miners play an increasingly important role in grid stability by acting as flexible energy consumers.

Bitcoin Miners Help Stabilize Texas Power Grid During Winter Storm

Mining operations can absorb excess electricity generated by wind or solar installations and rapidly power down during periods of peak demand.

Bitcoin ESG researcher Daniel Batten said on X that demand response programs involving miners helped stabilize the Texas grid during the storm.

The weather event also weighed on Bitcoin production. CryptoQuant analyst Julio Moreno said daily output dropped sharply at several major US mining firms.

According to a recent analysis by independent researcher Daniel Batten, Bitcoin mining can strengthen electrical grids and lower consumer electricity costs rather than strain power systems.

His research challenges common claims that mining destabilizes grids or drives up energy prices, drawing on peer-reviewed studies and operational data to argue that the industry’s flexible power usage can provide measurable system benefits.
