There is an economic calculation rationale why data centres are so susceptible to NIMBYing. When I worked with data centre developers, helping them in conversations with the UK government, the overwhelming argument is that the data centres’ economic impact is pretty low. In this context, economic impact = economic multiplier to a pound / dollar / yen of investment.

Economic impact can be calculated using any investment’s capex and opex: in capex, we have the building materials (predominantly non-local in this context) and employment from building a site (huge, but one-off). In opex, we have supply chain spend and employment. The last bit is what ultimately trips developers up, because employing people gives a substantial multiplier — people go on to spend their wages on goods and services, like barbers, and then barbers would go on to spend their wages on groceries, etc etc. This spend tends to trickle through the economy substantially. The materials used to build the centres are also largely imported, contributing negatively to the calculation.

And the above is the back of an envelope calculation. Once the appraisals start (appraisal = is this project worth doing, taking into account opportunity cost), the environmental and social impact will be taken into account, and those things also have an intrinsic £ / $ / ¥ value (you might be surprised that someone’s life also has an economic value). Worryingly, I am not aware of any appraisals being done, so it might be that the back-of-the-envelope calculation leaves it dead-on-arrival.

Now the benefit of a data centre transcends borders. So if I’m the UK government, I’d be asking myself why do we need to build in the UK, while a data centre infrastructure in France will use cleaner and cheaper energy (ie nuclear) and we still get compute at home. There’s of course more nuance here, but you can start to see how the NIMBY argument is, economically, hard to overcome.

I imagine the risk of a political backlash, perhaps coupled by a lack of international cooperation, is tilting the decision one way and one way only, even that means letting concrete slabs sit doing nothing with a slim chance an IKEA could be built there in the distant future.
