Electricity Theft Matches Barcelona and Sevilla Demand

Spain’s electricity-theft problem sounds abstract until you put a city next to it. Endesa says the power stolen on its network over the last five years adds up to roughly the annual electricity demand of Barcelona and Seville combined. That is not a rounding error. It is a sign that illegal hookups and meter tampering have become a parallel drain on the grid — and a much bigger crime story than the phrase “power theft” usually suggests. ### What actually happened? The new trigger for the story is Endesa’s 2025 fraud tally. The company says it uncovered 72,700 electricity-fraud cases last year across the parts of Spain where it operates — about 200 a day, or eight every hour. Over the 2021–2025 period, it says it closed more than 320,000 fraud files and recovered more than 3,750 GWh of stolen or diverted electricity. ### Why compare it to Barcelona and Seville? Because gigawatt-hours do not mean much to most people. The city comparison is the useful part. Endesa and follow-on coverage frame the five-year total as enough electricity to cover more than 1 million households for a year — or, put another way, about the combined annual demand of Barcelona and Seville. Basically, the point is scale: this is city-sized consumption disappearing into illegal use. ### Who is stealing that much power? Endesa’s line is blunt — the surge is not mainly about households quietly falling behind on bills. It says organized crime is a major driver, especially indoor marijuana cultivation. In Endesa’s own 2024 fraud update, 37% of the fraud it detected in 2023 was linked to marijuana growing, and cases together made up 74% of fraudulent volume. ### Why does cannabis show up so often here? Indoor grows are electricity-hungry. They run lights, ventilation, air conditioning, humidity control, and often do it around the clock. Endesa has said the average plantation can consume power on the scale of dozens of homes, which is why a single illegal connection can be a warehouse-level load hidden inside a residential area. ### Why does this matter beyond utility losses? Because stolen electricity is not just missing revenue. Illegal hookups can cause overloads, fires, electrocution risks, and repeated local outages. Endesa has repeatedly tied these fraud networks to safety problems for neighbors and local power supply annually. ### Is this a big share of Spain’s grid? In national terms, Spain’s total electricity demand in 2025 was 256,086 GWh. So the 3,750 GWh Endesa says it recovered over five years is still a small slice of the whole system. But that framing can be misleading. Grid stress is local, not average. A concentrated cluster of illegal high-load connections can hammer one district even if national demand looks fine. ### So what happens next? More inspections, more disconnections, and probably more policing around organized grows. Endesa has already been publicizing disconnections of illegal marijuana hookups and pushing the safety angle hard. The broader shift is clear — Spain’s power-theft problem is being treated less like petty fraud and more like infrastructure sabotage with a criminal-economy backbone. ### Bottom line This story is really about scale. Spain is not dealing with scattered meter tricks at the margins. It is dealing with industrial-size electricity theft that can swallow city-level demand, distort local grids, and turn an energy problem into a public-safety one.
