On September 8, 2026, Mexican authorities dismantled a clandestine cryptocurrency mining farm in Tlaola, a municipality in the northern highlands of Puebla, after tracing an abnormal electricity connection near the Nuevo Necaxa hydroelectric dam. Investigators seized around 300 specialized computers, transformers, medium-voltage equipment and satellite internet antennas.
The discovery turned an energy-theft investigation into a wider crypto enforcement case. Authorities had received reports of suspicious activity near the dam before locating the illegal power connection. The infrastructure suggests an operation built to sustain significant electricity demand while remaining geographically isolated, a pattern consistent with large mining installations that generate heat, noise and power consumption.
The precise cryptocurrencies being mined have not yet been identified. Investigators are also examining whether the site could be connected to money laundering, adding another unresolved layer to the case. Officials are expanding searches into nearby municipalities and potentially neighboring states after three similar mining operations were dismantled around Puebla and Tlaxcala during 2025.
The case reflects a broader global problem. Malaysia's utility lost about $1.11 billion to power theft associated with crypto mining between 2020 and August 2025, while U.S. police previously uncovered an unauthorized mining setup beneath a Massachusetts school.
