Mexican authorities have dismantled an illegal cryptocurrency mining operation in Tlaola, Puebla, after its significant energy consumption and noise alerted investigators. The operation was illegally drawing power from the Nuevo Necaxa hydroelectric dam, leading to the seizure of 300 mining machines, transformers, medium-voltage terminals, and satellite internet antennas.
The discovery was reportedly made after the state security minister noted the unusual energy usage and noise emanating from the property, according to the state security ministry. This method of detection highlights a growing challenge for authorities worldwide as illegal mining operations seek to exploit energy infrastructure. While cryptocurrency mining is legal in Mexico, the theft of electricity to power these energy-intensive operations is not.
Prosecutors are preparing charges for electricity theft, and investigations into potential money laundering are ongoing. The state government said it is examining whether assets produced by the operation were used for illicit financial activities. Mexico’s Federal Electricity Commission is also participating in the investigation.
This incident is part of a larger pattern of electricity theft by crypto miners, which has resulted in substantial financial losses for utilities. Between January and July 2024, non-technical losses from electricity theft, meter tampering, and illegal connections in Mexico amounted to 6,346 gigawatt hours, valued at approximately 13.8 billion pesos ($817 million). This underscores the significant economic impact of such illicit activities.
Authorities have previously cracked down on similar operations in the region. Three other mining operations were dismantled in Puebla and the neighboring state of Tlaxcala in 2025. Per reports in local media, a farm found near the same dam last year was allegedly operated out of properties belonging to the electrical workers’ union, though this claim has a low confidence level.
Globally, the problem of illegal crypto mining and electricity theft is widespread. In Malaysia, authorities seized over 75,000 mining rigs last year due to power theft, with an estimated value of $1.1 billion. Similarly, Brazilian police shut down an illegal operation in Rio de Janeiro.
Investigators are exploring whether this particular operation was part of a larger network exploiting the Sierra Norte’s hydroelectric infrastructure across neighboring states. The specific funding sources for the hardware and the full extent of any money laundering activities remain under investigation. The seized machines are described as GPUs, which could indicate they were used for mining cryptocurrencies other than Bitcoin, which typically relies on more specialized hardware.
The detection of this operation through its energy footprint and noise provides a crucial insight into how authorities are beginning to combat these clandestine activities. The ongoing investigations aim to uncover the full scope of the illegal enterprise and hold those responsible accountable, while also addressing the broader risks posed to energy infrastructure and the significant financial losses incurred.
Why This Matters
Authorities seized 300 crypto mining machines, transformers, medium-voltage terminals, and satellite internet antennas from a property in Tlaola, Puebla. Who funded the hardware remains uncertain, as does whether assets produced were used to launder proceeds of crime.
Broader Context
Mining is legal in Mexico, but electricity theft is not.
