Scotland’s debate over hyperscale data center development has shifted from the scale of proposed investments to a more immediate question: how should local authorities handle applications while the national government prepares its planning policy? The Scottish Greens have urged ministers to clarify their position after finding that several councils had received no guidance following the Scottish Parliament’s September 16 vote on a pause in hyperscale data center planning decisions. The amended motion called for authorities to defer relevant planning and consenting decisions until ministers completed the national guidance, while the Scottish Government had separately introduced notification and environmental assessment directions for qualifying data center developments.

However, the communications gap identified by the Greens has raised questions about how ministers expect councils to apply the parliamentary position under existing planning rules. The issue carries practical consequences because developers have already advanced proposals in several Scottish communities, including projects with substantial proposed electricity capacity and significant local opposition. The central question extends beyond the timing of individual planning decisions: can Scotland establish a consistent approach to large-scale digital infrastructure while balancing investment ambitions, local accountability and the demands of the energy transition?

Scottish Borders and Fife Projects Put the Dispute Into Focus

Scottish Borders Council confirmed through a Freedom of Information request that it held no correspondence from the Scottish Government or its officials concerning the proposed pause. The request sought “Any external correspondence with the local authority from or to the Scottish Government following the vote on AI hyperscale data centre applications regarding the plans for a pause and new national planning and spatial guidance.” The council’s response matters because Sunlaws Development Company, part of Roxburghe Estates, has advanced plans for a major hyperscale facility near Duns. Project records identify the proposed 225 MW Southside Data Centre as having reached the preliminary planning stage, with a Proposal of Application Notice on record and a full planning application still to follow.

Fife Council has also confirmed that it did not receive a notification instructing it to pause data center applications before ministers publish their guidance, according to the Scottish Greens. ILI Group has proposed the 600 MW Auchtertool facility, but the project now faces an additional environmental assessment requirement after Scottish ministers determined that it requires an Environmental Impact Assessment. The project’s scale makes the timing of national intervention consequential because a decision before publication of the new framework could precede the standards ministers intend councils to apply. Local communities and campaigners have opposed both the Duns and Auchtertool proposals, turning planning administration into a broader dispute over who should determine the acceptable scale and location of Scotland’s digital infrastructure.

First Minister’s Assurance Faces a Test of Implementation

The dispute has placed the First Minister’s public assurances under scrutiny following an exchange with Scottish Greens co-leader Gillian Mackay during First Minister’s Questions. The First Minister said: “What I and my ministers say in Parliament will be reflected in the communication and the interventions of the Chief Planner, operating within the statutory framework appropriate for such decisions.” His statement indicated that ministers expected the Chief Planner to communicate their parliamentary position while respecting the statutory framework that governs planning decisions. The Scottish Greens argue that the councils’ reported lack of correspondence undermines that assurance and leaves local authorities without a clear explanation of what the pause requires. Clear instructions would help councils apply a consistent approach while ministers develop the national rules.

Scottish Greens MSP Patrick Harvie has described the dispute as a gap between ministers’ parliamentary statements and the instructions councils receive through official channels. Harvie said: “The First Minister told the Scottish Parliament that what ministers say will be reflected in communications from the Chief Planner – but this is clearly not the case.” He continued: “Parliament voted for a pause and local authorities should have had an explanation of what this means in practice or a planning direction issued while the guidance is being drafted. The First Minister must set out clearly what is expected of local authorities and what this pause actually means.” His comments highlight the practical importance of written guidance in a planning system where councils assess individual applications while national policy shapes the treatment of major infrastructure proposals.

National Planning Guidance Becomes the Critical Deadline

The Scottish Parliament’s September 16 debate established a timetable for national planning guidance. According to the reported wording, ministers expected to report on progress by the end of the calendar year and publish the full guidance within 12 months. The parliamentary motion also called for authorities to make no planning or consenting decisions on relevant applications until ministers completed the guidance. However, the Scottish Greens’ subsequent findings indicate that councils still want clarity about how that position applies in practice and what communications they should expect from the government. A published framework could give authorities more consistent standards for environmental assessment, energy requirements and community concerns, but councils still need clarity about how to handle applications already under consideration.

Environmental assessment has also become a central part of the government’s response to the growth in proposed data center developments. On September 16, the Scottish Government issued a direction requiring Environmental Impact Assessments for qualifying new data center developments exceeding 50 MW of power capacity, effective September 17, 2026. Developments below that threshold remain subject to case-by-case assessment under existing regulations. The Scottish Greens have called for a broader national strategy that defines acceptable development standards and gives councils a consistent basis for evaluating proposals. Such a framework could help authorities assess the cumulative implications of multiple projects rather than examining each application in isolation. Ministers now face the task of translating stronger environmental scrutiny into a framework that addresses both individual sites and the combined demands of Scotland’s proposed development pipeline.

What the Scottish Government Must Clarify Next

Ministers must explain in writing what the September parliamentary position means for councils handling live hyperscale applications. Their clarification should establish whether authorities must defer decisions until ministers publish the national guidance, identify the formal mechanisms that support that approach and explain how councils should manage existing determination deadlines. Beyond the immediate pause, ministers must develop a national strategy that consistently considers environmental effects, electricity demand, infrastructure capacity and the distribution of local benefits and costs. A clear timetable and an explicit explanation of how the parliamentary motion interacts with existing planning directions could help councils, communities and prospective investors understand the applicable process while ministers develop the national framework.

Harvie has made the Greens’ position explicit, arguing that ministers should provide leadership rather than leave communities to confront major developments without clear national direction. He said: “The Scottish Government must show leadership on this rather than allowing well-funded tech billionaires to foist hyperscale data centres on communities that do not want them.” His remarks reflect the party’s opposition to what it sees as development proceeding faster than the policy safeguards needed to evaluate it, although the government’s final approach will determine the requirements councils must apply. Ultimately, Scotland must decide how to accommodate the growth of AI and digital infrastructure while ensuring that policymakers account for the cumulative effects of individual projects. Until ministers provide that clarity, the Scottish data center pause will remain both a test of government implementation and a debate over the future scale of hyperscale development.
