Scotland is becoming an electricity powerhouse. In 2025, Scotland generated a record 38.5 terawatt-hours of renewable electricity, with wind accounting for most of it. Scotland also exported a net 20.8 TWh of electricity during the year. At the same time, a huge pipeline of new renewable projects is being developed.
That is good news for the transition away from fossil fuels. But every major technological change creates opportunities as well as risks.
One question that deserves more attention is whether Scotland's abundance of renewable electricity could eventually attract something rather less welcome: hidden cryptocurrency mining operations connected to organised crime.
There is no evidence that Scotland is currently experiencing the sort of criminal crypto-mining activity recently uncovered in Mexico. But the Mexican case provides an interesting warning about what can happen when cryptocurrency, organised crime and large quantities of electricity come together.
Authorities in Puebla recently uncovered a clandestine cryptocurrency-mining operation containing more than 300 computers. It was located close to a hydroelectric facility and investigators are examining possible links to organised crime and money laundering.
The operation was not discovered because somebody necessarily knew that criminals were using cryptocurrency. Unusually high electricity consumption and the physical signs of the equipment helped attract attention.
That is an important lesson. Cryptocurrency is often thought of as something that exists entirely in cyberspace. But cryptocurrency mining is actually a very physical business.
The computers need electricity. They produce heat. They need cooling. They occupy buildings. They require communications equipment and maintenance.
And that could become increasingly relevant in Scotland. Scotland has some of the ingredients that legitimate data-centre operators are already interested in. It has enormous renewable-energy resources, relatively cool weather and large areas of land. The Scottish Government is actively encouraging investment in digital infrastructure and sees opportunities for Scotland to develop sustainable data centres.
There is nothing suspicious about that. Scotland needs new uses for its electricity and wants the economic benefits that come from attracting new industries. But the distinction between a legitimate high-energy computing facility and a criminal operation could become increasingly important.
A conventional data centre might be processing business information, artificial intelligence workloads or cloud computing. A cryptocurrency-mining operation is using electricity to generate digital assets. From outside, the physical infrastructure could look surprisingly similar.
That creates a potential challenge for regulators and law enforcement. A remote industrial building containing powerful computers and cooling equipment could be perfectly legitimate. But if its ownership is opaque, its electricity consumption does not match its declared business activity, or money is flowing through suspicious cryptocurrency wallets, the combination could warrant investigation.
There is, however, an irony here. The electricity that makes a crypto operation attractive may also be one of the things that exposes it.
Hundreds of powerful computers cannot operate invisibly. They consume electricity, generate heat and require cooling. That means cryptocurrency mining potentially creates a trail in the physical world as well as the digital one.
And Scotland is developing another capability that could make life increasingly difficult for criminals: the ability to follow the money once it enters the cryptocurrency system.
Crypto is sometimes described as anonymous, but that is misleading. Many major blockchains create a permanent public record of transactions. The difficulty for investigators is often establishing who controls a particular wallet.
Once that connection is made, investigators can potentially follow the movement of funds through the system and identify exchanges, businesses or individuals involved.
The UK is already strengthening its powers to deal with this problem. In Scotland, changes to proceeds-of-crime powers have expanded the ability of law enforcement to search for, seize and retain cryptoassets connected with criminal activity.
This means that criminals face a rather unusual problem. The technology they use to move money can also create a permanent record of where that money has been.
That does not mean cryptocurrency has suddenly become a foolproof weapon against organised crime. Criminal organisations can still use cash, shell companies, traditional banking systems and other methods alongside cryptocurrency.
Nor does it mean every crypto transaction is suspicious. The real issue is that criminals are increasingly operating across several systems at once. Energy, computing, banking, cryptocurrency and physical businesses can all become part of the same financial network.
That raises a question for Scotland as its renewable-energy industry expands. If thousands of megawatts of new wind, hydro, battery storage and other energy infrastructure are developed, should policymakers also be thinking about who ultimately consumes that electricity and what they are doing with it?
The answer should not be to treat renewable-energy projects or data centres as suspicious. Scotland needs both. Nor should cryptocurrency itself be treated as inherently criminal. Most cryptocurrency activity is legitimate.
The lesson is rather that energy policy, digital policy and economic-crime policy can no longer be treated as completely separate subjects.
Scotland is building an electricity system that could attract major new industries. That is an opportunity worth pursuing.
But electricity is valuable. Digital assets are valuable. And organised crime has always been attracted to valuable things.
The Mexican case provides a glimpse of how those worlds can meet.
There is also a wider lesson. Criminals may believe they have found a way of hiding money in cyberspace.
But their computers still need electricity and sometimes the easiest way to find a hidden digital business may be to look at what is happening on the electricity meter.
Could the Electricity Network Become Part of the Detection System?
There is an obvious difficulty in policing remote parts of Scotland. Authorities cannot simply drive around the Highlands checking what is happening inside isolated buildings. But they may not need to. As electricity networks become smarter, patterns of consumption could provide another source of intelligence.
A small rural property suddenly using electricity on an industrial scale, particularly if that consumption continues around the clock, would be unusual. So would a substantial new electricity connection for a business whose declared activities would normally require far less power. Network operators already have detailed information about electricity flows and connections, while smart meters are making consumption patterns increasingly visible.
That does not mean high electricity use should automatically trigger suspicion. Farms, workshops, data centres, heating systems and other legitimate businesses can consume large amounts of power. But electricity consumption could become one piece of a much larger picture. If unusual energy use coincided with an unexplained business operation, opaque ownership, suspicious financial transactions or other intelligence, it could provide a reason for further investigation.
There is an interesting irony here. Scotland's renewable-energy expansion could potentially make the country more attractive to energy-intensive criminal activity, but the same electricity infrastructure could also make that activity easier to detect. Cryptocurrency may exist largely in the digital world, but the computers that create it still need electricity, produce heat and occupy physical buildings.
In the future, the electricity meter could become another trail for investigators to follow.
There is, however, another question. Would the police themselves have the expertise to recognise what an unusual electricity pattern actually means? Probably not in every case. Reading a smart meter is one thing. Understanding what a particular pattern of demand says about the equipment operating inside a building is something quite different.
That expertise is more likely to sit with electricity-network companies and specialist engineers. This suggests that any serious attempt to use electricity consumption to identify hidden crypto operations would require cooperation between police, financial investigators and the energy industry.
A sudden increase in demand at a remote property might mean nothing more than a legitimate business expanding. But if the energy data, company records and financial intelligence all point in the same direction, investigators could have a much stronger reason to take a closer look.
The challenge for Scotland will be making sure that the people investigating the digital money also understand the physical electricity infrastructure behind it.
Could Scotland Test the Idea Before It Becomes a Problem?
Perhaps the time has come for government to test this idea rather than wait for a problem to appear.
Scotland could establish a small pilot involving electricity-network specialists, Police Scotland, financial-crime investigators and people with expertise in cryptocurrency. The purpose would not be to monitor every remote property or create a new system of surveillance. It would be to establish whether electricity-consumption patterns can provide useful intelligence when combined with existing information about companies, finance and criminal activity.
A trial could concentrate on a limited number of areas and use properly governed data to establish what constitutes genuinely unusual electricity demand. It could look at how often apparently suspicious patterns have perfectly legitimate explanations, how quickly investigators can establish the reason for unusual consumption and whether combining grid information with financial intelligence actually produces worthwhile leads.
That last point is important. It would be very easy to create a system that generates hundreds of "suspicious" cases but very few genuine discoveries. A pilot would allow government to measure whether the idea works before committing significant resources or changing the law.
It could also answer a question that is difficult to answer from theory alone: what does a hidden crypto operation actually look like on an electricity network?
The Mexican case provides a warning that cryptocurrency mining can leave a physical electricity footprint. Scotland has the opportunity to learn from that experience before such a problem necessarily appears here.
If the trial demonstrated that specialist grid knowledge could identify unusual energy use and help investigators uncover otherwise hidden financial activity, Scotland could then consider whether the approach should become part of a wider UK economic-crime capability.
There would also need to be clear safeguards. High electricity consumption must not become a reason to treat legitimate businesses, farmers or rural households as suspicious. The purpose should be to identify patterns that justify further investigation, not to assume guilt from an electricity bill.
That makes a small, carefully controlled trial potentially worthwhile.
It would be far better to test whether Scotland has a new economic-crime detection tool before criminals discover how to exploit the gaps in it.
