Planning Outlook for AI Data Centres in Scotland
The Scottish government has indicated that planning consent for large AI-focused data centres is “highly unlikely” to be granted within the next three months. Ministers said decisions on applications exceeding 50 megawatts of power capacity will be deferred until national guidance on data-centre planning is published, which they expect by Christmas. Existing and new applications must now include an environmental impact assessment (EIA). The government also ordered planning authorities to notify ministers of all new data-centre applications within a week of validation.
Background and Policy Context
The rapid expansion of artificial-intelligence services has spurred a surge in proposals for “hyperscale” data centres, a term that was rarely used a few years ago. Scotland’s abundant wind resources make it attractive to developers who can claim renewable electricity, yet transmission constraints mean much of that generation is currently unused. The government’s recent order aims to create a “level playing field” for developers while tightening environmental oversight. The move follows a prior directive that required ministers to be alerted to new applications promptly.
Data and Environmental Metrics
- As of 24 June, BBC Scotland News identified at least 23 projects in the planning pipeline, though many are viewed as speculative.
- The EIA requirement applies to facilities with power capacity over 50 megawatts; smaller projects remain subject to existing environmental regulations on a case-by-case basis.
- Colin Lindsay of Scottish Water’s commercial subsidiary reported that current data-centre water use averages 97 cubic metres per day, less than the consumption of Scotland’s libraries, but future growth could pressure drinking-water supplies.
- Dr Callum MacIver warned that additional electricity demand could increase reliance on gas during low-wind periods, potentially jeopardising climate targets.
- For comparison, Irish data centres consumed 23 % of the country’s electricity last year, contributing to higher consumer bills.
Official Statements and Government Response
Public Finance Minister Hannah Mary Goodlad told MSPs that the forthcoming national guidance will shape local authority decisions and that no large-scale approvals are expected before it is released. She framed the EIA mandate as a means to protect the environment while supporting economic opportunities from the emerging sector. The electricity system operator indicated plans to decouple electricity pricing from wholesale gas costs to mitigate price spikes, though analysts remain skeptical about its effectiveness.
Criticism and Opposition
The Scottish Greens have called for a formal moratorium on data-centre applications until a comprehensive national strategy is in place, describing the government’s measures as “the bare minimum.” Green MSP Patrick Harvie argued that piecemeal local decisions cannot address national strategic issues such as fossil-fuel backup, grid stability, and electricity pricing. Local resident Jamie Prentice expressed concerns that a proposed development at Blackdog, Aberdeenshire, would transform the landscape into an industrial estate, highlighting community opposition to the scale of proposed sites.
