Texas Public Utility Commission Sues Attorney General to Block Release of Cryptocurrency Mining Data
August 11, 2025 — The Public Utility Commission (PUC) of Texas has initiated a lawsuit against Texas Attorney General Ken Paxton in an effort to prevent the release of detailed information about cryptocurrency mining operations within the state. The dispute arises after The Texas Tribune and other media outlets requested data on power usage by crypto mining facilities, which the PUC contends should remain confidential citing concerns over potential terrorism risks.
Background: The Battle Over Crypto Data Transparency
Texas has emerged as a leading hub for cryptocurrency mining, particularly Bitcoin, attracted by the state’s expansive electric grid, favorable tax policies, and ample land. However, the exact scale of crypto mining operations and their impact on Texas’ electric grid remain murky due to a lack of public access to comprehensive data.
In February 2024, journalists from The Texas Tribune and Straight Arrow News sought access to information submitted to the PUC as part of Senate Bill 1929, passed by the Texas Legislature in 2023. The law requires cryptocurrency mining facilities with an electrical load exceeding 75 megawatts to register with the PUC by February 2025. However, when reporters requested details such as facility names, locations, ownership, and electricity consumption, the commission initially denied access.
The media organizations appealed to the Attorney General’s office, which ruled in May 2025 that the data should be publicly released. The PUC disagreed with this decision and consequently filed suit against AG Paxton in June.
PUC’s Security Concerns and Legal Arguments
In their June 27 legal filing, PUC attorneys argued that releasing the information could facilitate terrorism by giving malicious actors sensitive insights into Texas’ critical energy infrastructure. The filing stressed that specific details about mine locations, size, and load could be exploited to disrupt the energy grid.
The PUC’s position is that cryptocurrency mining operations should be classified as part of the state’s critical infrastructure due to their significant power consumption and role within the energy ecosystem.
However, Assistant Attorney General Blake Brennan countered in his May ruling that the PUC had not demonstrated that the requested information would reveal technical vulnerabilities or substantially aid terrorist activities. Brennan noted the commission’s arguments lacked specificity on how public data access would increase security risks.
The Role of Cryptocurrency Mining in Texas’ Energy Landscape
Texas’ Electric Reliability Council (ERCOT) has indicated that cryptocurrency mining already consumes an estimated 2,600 megawatts—equivalent to the electricity demand of the city of Austin on an above-average day. Moreover, American Electric Power (AEP) recently announced that an additional 5,000 megawatts of planned crypto mining capacity could connect to its Texas grid, essentially doubling the electricity load of Austin twice over.
Bitcoin mining operations are characterized by massive electricity demands but also by operational flexibility; mining computers can be turned off rapidly when the grid requires more power for residential or essential services. This “large flexible load” capability allows cryptocurrency mines to participate in ERCOT’s demand response programs, which pay operators to reduce consumption during peak load times, aiding grid stability.
Proponents of Bitcoin mining argue that the sector offers financial incentives for increased energy generation, including renewable sources, and provides valuable grid-balancing services. Critics, however, raise concerns about increasing electricity costs, regulatory gaps, and the social impact on communities hosting mining facilities.
Expert Perspectives on Transparency and Grid Security
Industry and academic experts have weighed in on the ongoing dispute. Joshua Rhodes, a research associate at the University of Texas at Austin, acknowledged that large controllable loads like cryptocurrency mines pose new challenges to grid management but advocated for increased data transparency to promote market efficiency and reliability.
Energy economist Ed Hirs of the University of Houston criticized the PUC’s lawsuit, calling it “a ridiculous spectacle” and favoring public access to cryptocurrency mining data.
Meanwhile, ERCOT officials have highlighted enhanced security measures and monitoring protocols but have not expressly categorized Bitcoin mines as critical infrastructure or disclosed whether such facilities have been targeted in attacks.
Conclusion
The lawsuit pits two competing priorities: the public’s right to transparency regarding powerful energy consumers and the state’s claims of safeguarding critical infrastructure from potential terrorist threats. The final outcome remains pending in Texas courts, with significant implications for the future regulation and oversight of cryptocurrency mining and Texas’ energy grid management.
