Climate Action Committee [Draft]

Environmental Impacts of Hyperscale Data Centres

Meeting date: 5 November 2026

Ariane Burgess

Thank you. I am hearing that you would need to be able to see behind the curtain of what both the UK and Scottish Governments have been doing. Maybe we do not have a sense of that from them and they are not communicating well enough about what they are doing with regard to the cumulative impact of hyperscale data centres.

Let me turn to Thomas Morstyn—[Inaudible.]

Sorry, I was muted.

You talked earlier about the grid—“stability” and “grid stress” were among the terms that you used. I am interested in getting from you a sense of how feasible you think it would be to assess the cumulative impact of data centre energy demand in Scotland.

Wim, I will direct my first question to you. Your written evidence sets out a compelling argument that the energy consumption of the hyperscale data centres that are currently proposed would make it very difficult for Scotland to achieve its net zero targets by 2045. Has there been enough scrutiny by Government of the cumulative impacts of data centre energy consumption?

Given Craig Melson’s definition of a hyperscale data centre as one of 100MW capacity, that would mean that the 23 applications that have been made would basically amount to a pipeline in Scotland comparable to 90 hyperscale data centres, because the ones in the planning application process are much bigger than 100MW. Is it realistic for Scotland to host that much? What should the guidance say about how much is acceptable?

With regard to land use, you talked about ensuring that we do not build on greenfield sites and good farmland but prioritise brownfield sites first. Given that, should the Scottish Government’s guidance include a requirement to prioritise brownfield sites first?

Meeting date: 5 November 2026

Ariane Burgess

Good morning to the witnesses, and thank you for joining us. I have a number of questions: one is on siting and one is on land use.

The National Energy System Operator suggested that siting data centres in Scotland could reduce constraint payments, investment in transmission grids and, ultimately, electricity bills, and the Economy, Tourism and Energy Committee heard from Dr MacIver, who said that data centres would help if they were on switched-off wind and were north of the B4 boundary.

Mr Weir, in your submission for ScotlandIS, you accepted that grid connections are a decisive barrier. I would be interested to hear from you about what the Government’s guidance should say about where data centres should go and how much capacity Scotland can take. You have touched a little bit on capacity, but I am interested in that and the guidance.

Great. Thank you for that.

Let me come back to Wim Vanderbauwhede. Paragraph 45 of your submission to the committee, on the “Impact of embodied emissions”—you might have touched on this a little bit already—outlines the challenges of meeting net zero posed by embodied emissions from AI data centres. At the end of that paragraph, you say that

“If the capacity was capped at 500 MW, the increase”

—it gets a bit technical after that—would be “acceptable”.

Do you think that capping total capacity at 500MW by 2030 would be acceptable? Should the Government put such a limit in its guidance?

Let us talk about both Governments, maybe.

My question is directed to Wim Vanderbauwhede, who talked earlier about having smaller and more dispersed data centres that would have less environmental impact. Can you clarify what would happen in those data centres? Public sector reform is going on in Scotland at the moment, and in those discussions, certainly with local government, academia and so on, people are expressing great hope that certain aspects of AI will be able to help with the toil of things—to use a term that was used last week. Is that the kind of thing that would happen in these smaller, more environmentally dispersed data centres, or could things such as ChatGPT run in them, too?

I will stay with you, because you mentioned NESO. NESO suggested that siting data centres in Scotland could reduce constraint payments, reduce the need for investment in the transmission grid and, ultimately, reduce electricity bills. On top of that, electricity carbon intensity is lower in Scotland. I would like to get your view on those points about constraint payments and investment in the grid, and on whether it really would—[Inaudible.]

Sorry—I keep getting muted. I do not know what is going on.

Anyway, at our previous meeting, we heard from the folks in Ireland that their electricity bills have actually gone up. I would like to hear your thoughts on that.
