Russian police in the Nizhnetavdinsky District of Tyumen Oblast have uncovered a major illegal cryptocurrency mining operation organized by a large family.
Criminal cases have been opened against six villagers accused of causing property damage by abusing discounted electricity tariffs intended for households with multiple children.
Law enforcement officers seized approximately 2,000 units of mining equipment from the secret site. According to investigators and regional power supplier Gazprom Energosbyt Tyumen, the organizers masked their energy-intensive digital currency extraction as ordinary domestic electricity consumption.
Tyumen Oblast is a major resource-rich region in Western Siberia, where power infrastructure is heavily monitored. Gazprom Energosbyt Tyumen is the principal electricity provider across the region. Cryptocurrency mining requires vast amounts of electrical power to run continuous computer calculations that validate transactions and generate new digital coins.
Subsidized Power Tariffs
Gazprom Energosbyt Tyumen did not disclose the precise monetary value of the damage caused by the farm. However, the energy company stated that the family took advantage of subsidized utility rates reserved for multi-child households to lower their operational costs.
Tyumen Oblast operates a tiered electricity pricing system designed to charge higher rates for heavy energy consumers. The structure is divided into three monthly consumption bands: up to 3,900 kilowatt-hours, between 3,901 and 6,000 kilowatt-hours, and anything above 6,000 kilowatt-hours. Under regional regulations introduced last year, qualifying large families receive the lowest tier one rate regardless of how much electricity their property consumes.
Energy officials noted that law enforcement inspections of suspected mining operations are most frequently triggered by complaints from local residents who notice unusual power surges or equipment noise.
Widespread Grey Mining Inspections
The discovery in Nizhnetavdinsky District is part of a broader crackdown on unauthorized crypto mining across the region. Officials revealed that another mining setup was discovered inside the house of a large family in the village of Isetskoye in the same district.
In a separate case in the village of Mezenka, located within the Ishimsky District of Tyumen Oblast, a resident set up a cryptocurrency mining operation inside his private garage.
Gazprom Energosbyt Tyumen reported that more than 30 cases of grey mining have been recorded across Tyumen Oblast over the past year. While cryptocurrency mining remains legal in the region, using residential grid subsidies for commercial mining is treated as illegal utility exploitation.
Legal Precedents and Penalties
Russian courts have increasingly handed down criminal sentences to individuals caught operating unauthorized mining facilities at the expense of power companies.
In a previous case, a court sentenced a resident of Chapaevsk, a town in Samara Oblast, to one and a half years of forced labor for illegal mining. Prosecutors in that trial demonstrated that the local power supply company suffered severe financial losses exceeding 91 million rubles.
Forced labor in the Russian judicial system serves as an alternative to imprisonment for non-violent crimes, requiring convicted individuals to work at designated facilities with a percentage of their earnings deducted for the state budget.
