Mexico seizes 300 crypto mining rigs at hydroelectric dam

Mexican authorities removed 300 cryptocurrency mining rigs from a hydroelectric dam after discovering unauthorized connections to the plant’s electrical system in a recent enforcement operation.

Officials found the machines tied into the dam’s power lines. Technicians disconnected the rigs from the facility’s circuits while law enforcement secured the site and confiscated the hardware.

The devices are being cataloged as part of a criminal inquiry into illegal use of electricity. Authorities provided no immediate information on arrests or who owns the equipment.

Cryptocurrency mining rigs are specialized computers that perform continuous calculations to validate digital currency transactions. They require steady, high levels of power to run and can add significant load to an electrical system when connected without permission.

Energy theft is a legal offense in Mexico. Unauthorized connections can cause financial losses for utilities and affect reliable power delivery. The presence of hundreds of high-demand machines at a hydroelectric facility can increase stress on equipment and complicate maintenance and safety work.

Investigators will determine how the rigs were connected to the dam, who organized the operation, and whether the incident caused damage or interrupted normal power generation.
