Rio de Janeiro Civil Police raided a Comando Vermelho operational nucleus and uncovered a roughly 30-machine crypto mining farm running on a clandestine electrical tap off a utility pole, in an apparently abandoned lot in the Complexo do Lins. The setup sat on shelves with high-capacity fans, exhaust systems, and remote-monitoring hardware — a configuration that lets a single operator run a facility without being physically present, and that converts a stolen kilowatt-hour into a transferable digital asset. G1 reported that police are now investigating whether the faction used the structure for money movement or laundering, but the physics of the rack already describe the model: territorial control supplies the space, the clandestine line kills the dominant variable cost, and the hash output is portable by design.
Why it matters
Electricity is the load-bearing input. At 1.5 kW per machine and 30 rigs, the farm would draw about 45 kW and consume roughly 32,400 kWh a month — a $6,400 monthly bill at Brazil's residential tariff of $0.20 per kWh, a cost the clandestine connection zeroes out. ANEEL, Brazil's electricity regulator, put energy theft and other non-technical losses at roughly $2 billion for 2024, with Rio among the highest-theft states. The farm is therefore not a fringe curiosity; it is a documented case of organized crime treating the grid as a free input to a margin-heavy production process. Cambridge's Bitcoin Electricity Consumption Index methodology treats electricity as one of mining's largest variable costs — strip it out and the unit economics change.
Market impact
The Rio case lands inside a wider Brazilian enforcement picture. Folha reported on May 9 that Federal Police seized $14 million in crypto in 2025 across drug trafficking, laundering, and environmental crimes, and a May 12 operation across 16 states executed 165 search-and-seizure warrants and 71 arrest warrants targeting factions and laundering. Chainalysis' 2026 Crypto Crime Report describes the illicit on-chain economy as having built infrastructure to help transnational networks procure goods and launder crypto.
Frequently asked questions
-
What did Rio police find in the Comando Vermelho raid?
Civil Police raided a CV operational nucleus in the Complexo do Lins and found a roughly 30-machine crypto mining farm running on a clandestine electrical tap off a utility pole, shelved with high-capacity fans, exhaust, and remote-monitoring hardware.
-
How much electricity did the farm consume?
At 1.5 kW per machine and 30 rigs, the farm drew about 45 kW and consumed roughly 32,400 kWh a month — a $6,400 monthly bill at Brazil's $0.20/kWh residential tariff, all of it avoided via the stolen connection.
-
What is the 'stolen power' crypto-crime model?
A criminal group uses territorial control to secure space and a clandestine utility tap, eliminating mining's largest variable cost, then runs off-the-shelf hardware to convert free electricity into portable digital value that can be moved or laundered.
-
How big is energy theft in Brazil?
ANEEL, Brazil's electricity regulator, put energy theft and other non-technical losses at roughly $2 billion in 2024, with Rio de Janeiro among the states recording the highest levels of power theft.
-
Is this model unique to Brazil?
No. Malaysia's national utility, Tenaga Nasional, lost more than $1 billion to illegal power use by crypto miners between 2020 and August 2025, prompting raids, smart-meter rollouts, and suspect-premise databases.
