Key Points
- Actor Sam Heughan publicly backed calls for an immediate moratorium on hyperscale AI data centres across Scotland.
- The Scottish Greens triggered a vote in the Scottish Parliament to pause all data centre applications over 50 megawatts.
- Environmental campaigners said the first 24 proposed data centres would require 1.5 times the total peak winter electricity consumption of Scotland.
- Scottish Ministers introduced mandatory notification rules for councils regarding new applications, but the government has not issued a statutory moratorium.
- Campaign group Stop Climate Chaos Scotland and members of the SNP National Council backed the Green motion against unregulated data centre expansion.
Edinburgh (Edinburgh Daily) September 16, 2026 – The Scottish Greens have welcomed public backing from actor Sam Heughan as politicians prepare for a pivotal vote in the Scottish Parliament regarding the future of artificial intelligence infrastructure across the country. Green MSPs are forcing a parliamentary vote urging Ministers to enact an immediate statutory moratorium on all new data centre applications with a capacity exceeding 50MW until a comprehensive national strategy and regulatory framework are established.
As reported by The NEN, actor Sam Heughan urged MSPs to intervene directly in the current planning regime, stating: “listen to what communities and environmental organisations are saying” and halt climate-wrecking data centre applications until a national strategy is in place.
The intervention comes amidst mounting anxiety regarding the rapid proliferation of speculative developments submitted to local councils. Stop Climate Chaos Scotland, a prominent coalition of environmental and civil society organisations, has formally aligned with the demand for a pause due to what they characterise as “profound concerns about the environmental impacts of these mega data centres” on national carbon targets and local ecology.
How Scale and Energy Demands of Proposed Facilities Threaten the Grid?
The debate centers on the unprecedented physical and electrical scale of modern AI-focused computing facilities. According to figures highlighted by Green MSPs, the volume of speculative proposals currently making their way through the Scottish planning pipeline risks entirely swamping the national electricity network.
As documented in official statements issued by the Scottish Greens, Co-Leader Patrick Harvie MSP stated: “Sam Heughan is right that the Scottish Government should listen to communities and campaigners who are calling for a moratorium. We need an immediate pause on these applications until we can assess the impact on our energy systems and local environments”.
Harvie further detailed the operational strain these facilities present, adding: “Today’s vote gives MSPs their first opportunity to put the brakes on this speculative rush to build massive new AI data centres. Scotland is being hit by a huge surge of hyperscale AI data centre proposals, and the Scottish Government is standing by while councils are being left to deal with the consequences”.
He added that: “The scale of what is being proposed is extraordinary. If the first 24 of these projects are approved they will require one and a half times Scotland’s entire peak electricity consumption. It is completely unsustainable. We cannot allow a big tech free-for-all”.
What Is the Current Scottish Government Position on Data Centre Expansion?
Despite growing pressure from environmental groups, backbench politicians, and public figures, the Scottish Government has so far resisted calls to enact a complete ban or pause on developments. Last month, Scottish Ministers implemented administrative changes requiring local authorities to inform central government whenever a new data centre application is registered. However, ministers have consistently stopped short of issuing a formal direction to halt determination procedures.
Critics argue these administrative steps fail to address the core problem facing local planning departments. As reported by The NEN, Patrick Harvie MSP noted that: “The current approach from the Scottish Government is unsustainable. MSPs can show support for local communities by backing our calls for a proper national strategy and demanding the halt that is needed”.
He further emphasized: “We cannot approve such huge new demands on our energy system without first asking whether these projects are in Scotland’s interests, where the power will come from, and who will ultimately benefit… We need to put robust criteria in place, and make sure Scotland’s energy, land and infrastructure are working in the public interest rather than being handed over to the big tech industry on a speculative basis”.
The parliamentary motion has created political friction, with members of the SNP’s own National Council and several SNP MSPs previously expressing sympathies for a controlled, strategic pause, contrasting with Holyrood’s official executive stance.
Background of the Data Centre Moratorium Controversy
The debate in Holyrood mirrors broader UK-wide and global friction between digital infrastructure expansion and climate commitments. In late August 2026, Green Party leaders in England similarly demanded a temporary ban on facility approvals due to severe stress on regional water tables and power grids. Following the UK Government’s designation of data centres as Critical National Infrastructure (CNI) in 2024, local authority planning departments across Britain experienced a surge in applications from multinational technology firms seeking site allocations for high-density AI clusters.
While central governments have sought to attract global tech investment to drive digital innovation, municipal authorities and environmental groups argue that without statutory limits, hyperscale server facilities risk cannibalising renewable energy generation intended to decarbonise domestic heating and transport networks.
Prediction: How Will This Development Affect Scottish Communities and Industry?
Should the Scottish Parliament vote to enforce a statutory moratorium, the decision will immediately alter the landscape for local communities, technology investors, and energy suppliers:
- Local Communities: Residents living near proposed developments would experience an immediate relief from planning uncertainty. A formal halt would allow local authorities to establish clear standards regarding noise, visual intrusion, and local grid preservation, ensuring residential water and power supplies are protected from resource competition during peak periods.
- The Technology and Investment Sector: Multinational tech corporations and infrastructure developers would face project delays in Scotland, likely forcing capital toward alternative European jurisdictions with available grid capacity or less restrictive planning controls. However, a structured national strategy could eventually offer investors long-term regulatory certainty and clearer pathways for clean energy integration.
- Energy Network Operators: A temporary freeze would provide grid operators, such as SSEN Transmission and SP Energy Networks, crucial operational breathing room to model real-world demand. This would prevent localized bottlenecks and ensure renewable power generation is prioritized for national net-zero goals rather than speculative commercial developments.
