Scottish Greens Push to Pause Data Centres, and Why That's the Wrong Answer for Scotland

The Scottish Greens want Holyrood to follow New York's moratorium on new data centre development, citing energy demand and environmental concerns. It's a well-intentioned call. It's also the kind of policy that could hand Scotland's AI infrastructure opportunity to someone else, permanently.

New York State enacted a moratorium on new cryptocurrency and energy-intensive data centre development in 2022, citing strain on its electrical grid and carbon targets. The Scottish Greens are now pushing for something similar here, arguing that data centres threaten Scotland's renewable energy surplus and net-zero commitments. The instinct to protect the grid is understandable. The policy conclusion is wrong.

Scotland is not New York. New York's grid problem was partly driven by energy-hungry proof-of-work cryptocurrency mining operations, a specific, largely unproductive load. Scotland, by contrast, has one of the most consistently renewable electricity grids in Europe. According to Scottish Renewables, Scotland generated the equivalent of 113% of its electricity consumption from renewables in 2023. The problem isn't too much demand, it's too little infrastructure to use the surplus we already generate. A well-sited AI data centre doesn't strain that grid. It makes use of power that currently goes to waste.

The waste heat dimension is the part this debate is missing entirely. Modern AI server farms run hot. That heat, properly captured and routed, can warm homes, hospitals, schools, and commercial buildings through district heating networks. Copenhagen already heats tens of thousands of homes this way, using waste heat from data centres and industrial processes. Stockholm's data centre industry contributes meaningfully to the city's district heating supply. Scotland has the cold climate, the land, the renewable generation, and the planning ambition to do the same, and at greater scale. A moratorium closes that door before it's properly opened.

There is a legitimate conversation to be had about planning, siting, and grid connection for new data centre development. Not every rural location is suitable. Community benefit agreements matter. Transparency around energy use and heat recovery should be mandatory, not optional. The Scottish Government's own Digital Strategy and net-zero framework both point toward managed growth of digital infrastructure, not a freeze. Research from the University of Edinburgh's School of Engineering has highlighted the untapped potential of waste heat recovery in Scottish urban environments, potential that disappears if the infrastructure is never built.

For Scottish SMEs, the stakes here are practical and immediate. AI compute infrastructure in Scotland means faster, cheaper, lower-latency cloud services for businesses based here. It means jobs in construction, operations, and engineering. It means the possibility, already being explored by several Scottish councils, of near-zero-cost heat for public buildings and social housing. A moratorium, even a temporary one, tells global investors in AI infrastructure to look at Ireland, or the Netherlands, or the north of England instead. Once that capital moves, it doesn't come back quickly. Scotland has a narrow window to be part of the AI infrastructure map. Closing planning doors now, before proper waste heat and grid frameworks are even legislated, is a costly mistake dressed up as caution.

What this means for you: If you run a business that relies on cloud computing, AI tools, or digital infrastructure, the data centre policy debate at Holyrood is directly relevant to your future costs and service quality. Watch the Scottish Government's response to this Greens push closely. If your council or local authority is exploring district heating, it's worth asking whether AI infrastructure waste heat is part of that conversation, because in several Scottish cities, it already is.
