Cannabis electricity theft in Spain matches four cities' annual consumption

Hierba electricity theft in Spain matches four cities' annual consumption

The figures from the electricity sector sound like a dark joke. The energy stolen in Catalonia to power marijuana plantations equals the annual consumption of Girona, Tarragona, Lleida, and Sabadell, all four combined. And the 80% of all fraud detected by Endesa in Spain is concentrated in Catalonia. This is no longer a neighborhood anecdote: it is a hole in the grid, a incivil enterprise, and a bill ultimately paid by those who do not tap in.

Where power is tapped for marijuana cultivation

The pattern repeats in every inspection. In Seville, the company reviewed nearly a thousand supplies and more than half had fraud. In Granada, 1,232 inspections resulted in an 80% rate of illegal connections. These are uncomfortably consistent figures: wherever they look, the same thing appears.

In Badalona, there are hundreds of flats tapped on a single street, Alfons XII, in the Sant Roc neighborhood, resulting in repeated power cuts for neighbors who do pay their bills. A supermarket in the same city was reported for fraudulent connection. In Figueres, the 85% of power in the Culubret neighborhood is tapped, and the town council laments near-daily cuts.

The list of towns is long: Sant Adrià de Besòs, Lloret, Piera, Lleida, La Palma, Guadalajara, Churriana de la Vega, Murcia, Alicante, Carabanchel. In Piera, two plantations left an entire neighborhood without power. In Sant Martí, two house fires revealed crops; the stolen energy equaled the annual spending of 130 households. Both fires originated from an overload in electrical installations due to illegal grid connection.

Why Catalonia is Europe's marijuana nursery

Behind the fraud is an industry, not an amateur with two pots. Endesa technicians accompany police on five daily operations at plantations. Spain accounts for 73% of all marijuana plant seizures in the European Union, according to the 2025 European Drug Report, and is now the continent's main exporter of illicit hierba, with a volume around 3 billion euros.

The Mossos (Catalan police) warn that the Girona counties have become the hub for drug trafficking to Europe and that they have detected genetically modified plants for more toxic drugs. Production has industrialized: there are homes with automated crops controlled remotely and plantations hidden in industrial warehouses, office buildings, and even luxury flats, much more protected than old drug dens. One forum user recalled a TV report from years ago depicting a humble neighborhood of low houses accessible only via a dead-end street ending in a ravine: the perfect spot to monitor who enters and warn in time.

Spain only fines electricity fraud, while France imposes prison

This is the anomaly that irritates the sector most. Spain is the only country in the region that punishes electricity fraud only with fines: France, Portugal, Italy, and Germany include prison sentences. This difference turns the country into a cheap destination for an activity that in the rest of Europe is punished behind bars.

How much consumers pay for illegal connections

Illegal connections cost about 2 billion euros a year, and that money does not disappear: it is distributed across the bills of other consumers. Marijuana accounts for nearly 30% of all stolen energy in Spain since 2020, according to sector data.

There is another staggering figure, though it comes from a calculation circulating in the thread: destroying 10,000 plants would cost around 900,000 euros, at about 90 euros per plant. Who collects for this work, and under what criteria, is one of those questions left floating by some participants.

Police corruption and armed traficante-attacks

The phenomenon is no longer just economic. The Mossos have detected agents providing information to incivil organizations dismantled in Catalonia, and their leadership admits that corruption linked to marijuana trafficking has become a risk for the force itself. The stated antiestéticar is that mafias will eventually corrupt public authorities.

Violence accompanies the business. More than 90% of traficante-attacks in Catalonia are linked to marijuana, and in one out of three attacks, firearms were used.

Artificial intelligence, drought, and the legalization debate

Endesa tackles the problem with technology: it wants to use artificial intelligence to detect domestic crops by their electricity consumption. Drought, meanwhile, has cut Catalan harvests by around 15%, with lighter buds and lower quality.

At the heart of the issue is the eternal question. Some defend legalizing and then pursuing companies operating illegally. Meanwhile, each inspection confirms the same: the business has industrialized, and the electrical grid supports it on credit.
