Many areas of the Lone Star State experienced subzero temperatures in January — a weather event that has previously led to Bitcoin miners temporarily curtailing operations.
A sudden freeze in Texas may have contributed to a 34% drop in the Bitcoin hash rate, as some miners were forced to curtail operations amid demand on the state’s energy grid.

Beginning on Jan. 14, temperatures in many parts of Texas dropped below freezing for one of the first times since a massive ice storm in February 2023. According to data from YCharts, the total Bitcoin BTC $42,622 network hash rate fell from more than 629 exahashes per second (EH/s) on Jan. 11 to roughly 415 EH/s on Jan. 15 — a 34% drop. The analytics site reported the hash rate increased to more than 454 EH/s on Jan. 16 as temperatures in Austin briefly rose above freezing during the day.

According to Foundry’s data pool, Texas accounted for roughly 29% of the Bitcoin hash rate in the United States. Many mining firms relocated to the state from China following the country’s crackdown on BTC miners and crypto. Several firms have operations in Texas, including Marathon Digital, Riot Platforms, Bitdeer and Core Scientific.

Unlike in 2021, when record low temperatures and a sudden winter storm caused hundreds of power outages to homes at a time when many roads were covered in ice and heavy snow, there were fewer reports of significant disruptions to Texas’ power grid. Many mining firms have joined a program organized by the Electric Reliability Council of Texas (ERCOT) that compensates them for adjusting their load on the state’s power grid during periods of high demand.

“Marathon, along with other Bitcoin miners, have been curtailing operations to support the Texas electric grid and the citizens of the state, who have been battling sub-zero temperatures,” Charlie Schumacher, vice president of corporate communications at Marathon Digital, told Cointelegraph. “This is precisely how the system should be working. Bitcoin miners serve as base load that turns off during extreme weather events, making energy more abundant and cheaper for those who need it within minutes.”

A Riot spokesperson added:"Riot actively participates in demand response programs, allowing ERCOT to manage the Company’s load when assistance is crucial for balancing the grid amid challenging weather conditions.”
