Mexican authorities seize 300 rigs from illegal Puebla crypto mine

Mexican federal police and Navy investigators dismantled a 300-machine cryptocurrency mining operation in Tlaola, Puebla, after tracing an unauthorized power line into infrastructure tied to the Nuevo Necaxa hydroelectric dam.

Authorities are now examining whether similar operations may be operating in neighboring municipalities.

The case has drawn attention not because cryptocurrency mining is prohibited in Mexico, but because of the alleged unauthorized use of electricity to power the operation. Mexico’s Federal Electricity Commission (CFE), the Attorney General’s Office and the Navy are participating in the investigation.

Authorities dismantle crypto mining farm in Puebla

The crypto mining farm was discovered near major federal hydroelectric infrastructure, where investigators identified what authorities described as a significant unauthorized power connection.

The scale of the facility appears to have played a role in exposing the operation. Cryptocurrency mining can require substantial computing power, with specialized machines consuming large amounts of electricity while operating continuously. In this case, investigators found approximately 300 GPU-based machines connected to equipment capable of supporting the operation.

The discovery prompted authorities to dismantle the facility in Tlaola and expand their examination beyond the site itself. Officials are assessing whether other municipalities in the surrounding area may contain comparable installations.

The investigation is therefore focused on the alleged electricity theft rather than cryptocurrency mining as an activity. Mining digital currencies remains legal in Mexico, according to the information provided in the original report.

The involvement of the CFE, federal prosecutors and the Navy underscores the broader nature of the inquiry, particularly as investigators work to establish how the unauthorized connection was created and who was responsible for the operation.

Electricity losses add pressure to crypto enforcement

The Puebla crypto mining farm comes against the backdrop of significant electricity losses recorded by Mexico’s state-owned power utility.

CFE recorded 6,346 gigawatt-hours (GWh) in electricity losses between January and July 2024. The losses were estimated to have a commercial value of 13.8 billion pesos, equivalent to approximately $817 million.

Those figures provide important context for the investigation because large-scale unauthorized electricity consumption can create financial losses for the power system. The Puebla case gives authorities another example to examine as they investigate possible illegal connections associated with energy-intensive cryptocurrency operations.

The suspected power theft also distinguishes the case from legitimate cryptocurrency mining activity. While operators can legally engage in mining, they remain subject to applicable electricity and infrastructure rules.

For investigators, determining how much electricity the facility consumed, how the connection was established and who benefited from the operation will be central to understanding the alleged offense.

Crypto mining farm raises money laundering questions

Beyond the electricity investigation, authorities could also examine whether the crypto mining farm was connected to potential money laundering involving digital assets produced through the operation.

Investigators want to determine whether cryptocurrencies generated at the facility may have been used to conceal or disguise proceeds from illicit activity. At this stage, however, it has not been establish that money laundering occurred or the identify any individuals as responsible.

The potential financial investigation adds another dimension to the case. Digital assets can be transferred across borders and between wallets, meaning investigators may examine transaction records alongside physical evidence recovered from the site.

However, the central allegation currently concerns the unauthorized electricity connection. Authorities must establish the facts surrounding the operation before broader criminal conclusions can be drawn.

Previous crypto mining farm discoveries widen probe

The Puebla crypto mining farm is not the first facility of its kind to come under scrutiny in the region.

Authorities dismantled three other mining facilities between Puebla and Tlaxcala during 2025. The latest discovery could therefore provide investigators with additional grounds to examine whether the operations are connected or whether similar unauthorized facilities are operating independently.

The repeated discoveries have also increased scrutiny of energy-intensive cryptocurrency mining and its potential impact on Mexico’s electricity infrastructure.

For authorities, the investigation into the latest crypto mining farm could ultimately extend beyond Tlaola if evidence points to additional sites. Investigators are already examining neighboring municipalities as they seek to determine whether the Puebla operation was an isolated case or part of a wider pattern.

The dismantled crypto mining farm also highlights the distinction between cryptocurrency activity itself and the methods used to conduct it. Mining remains legal in Mexico, but allegedly stealing electricity to support such an operation can trigger enforcement action.

As the investigation continues, authorities are expected to focus on the unauthorized power connection, the ownership and operation of the equipment, and any financial activity associated with the cryptocurrencies generated at the site.

The case leaves the crypto mining farm at the center of a wider examination of electricity theft, digital assets and potential financial crimes in the region, while authorities assess whether similar operations remain active elsewhere in Puebla and neighboring areas.
