Scotland’s data centre reckoning part 5: What Scotland can do right now

THIS SERIES HAS DOCUMENTED four failures: a planning system processing twenty hyperscale applications without cumulative assessment; a cost framework that hides hundreds of pounds per household in grid charges while directing public subsidy to trillion-dollar corporations; a water abstraction regime that allows developers to declare demands bearing no relationship to what their cooling systems will actually consume; and an EMF infrastructure gap that places high-voltage transmission lines beside communities without requiring the field measurements needed to show whether those communities are within a zone of documented health concern.

Each failure is real and documented on the public record. Each is the product not of malice but of a planning system designed for a different era, now being asked to process applications at a scale it was never built to handle.

Each failure also has a fix – one that does not require a new Act of the Scottish Parliament, Westminster‘s permission or a wait for a national planning framework review that could take years. The Scottish Energy Compact sets out four conditions of consent that can begin operating immediately, and five demands that can be acted upon before the end of this parliamentary session.

The four conditions

The Compact conditions are planning conditions. They are attached to planning consent under existing powers available to Scottish planning authorities and, by ministerial direction, to all authorities simultaneously. They do not regulate the electricity market, they do not set energy prices, and they do not purport to override reserved powers. They set the terms on which consent is granted – which is precisely what planning conditions are for.

Condition One requires every hyperscale facility above 200 megawatts to demonstrate, before consent is granted, a contracted pathway to firm, dispatchable power supply for one hundred per cent of its maximum demand, at full cost-reflective grid charges. No grid reinforcement, capacity market, or balancing cost triggered by the facility may be socialised onto the wider consumer base. The developer must demonstrate viability without externalising infrastructure costs onto households.

Condition Two requires a mandatory Section 75 planning obligation committing each developer to contribute £15 per megawatt-hour of electricity consumed into a ring-fenced Community Energy Fund, administered by the relevant local authority and applied exclusively to energy efficiency measures and bill relief for residents in the hosting area. For a 500 megawatt facility, this is £52.5 million per year – a direct, measurable return to the communities bearing the costs of hosting facilities that the UK Government is simultaneously subsidising at £84 million per year.

Condition Three prohibits evaporative cooling for all facilities above 200 megawatts. Closed-loop or air-side economisation cooling is mandatory. Every applicant must submit a Water Usage Effectiveness declaration, independently verified, specifying the cooling system and the resulting maximum daily abstraction volume. A SEPA Environmental Authorisation for water abstraction must be confirmed in principle before planning consent is granted – not after.

Condition Four requires a 100-metre planning setback from any new 275 kilovolt or 400 kilovolt overhead transmission conductor or substation perimeter fence to the nearest residential property, school, or hospital. Every applicant must publish a grid connection statement identifying all above-ground infrastructure, substation footprints, and modelled field contours at 50, 100, and 200 metres from residential properties before the application is determined.

The mechanism

Planning conditions of this type can be introduced by ministerial direction to all Scottish planning authorities simultaneously, requiring that no application above 50 megawatts be registered as valid without the declared information, and that no consent above 200 megawatts be granted without the conditions attached. This requires no primary legislation. It requires the Cabinet Secretary for Net Zero and Energy to sign a direction.

That direction can be reinforced by a Planning Circular – guidance to planning authorities on how the conditions should be applied – and consolidated permanently by a targeted update to NPF4 Policy 24 (Digital Infrastructure) in the next framework review. The temporary direction and circular can operate immediately, before any review is complete.

Five demands this session

Beyond the Compact conditions, five immediate actions can be taken within this parliamentary session using powers that already exist.

First, a twelve-month moratorium on all data centre consents above 200 megawatts, pending a government-commissioned cumulative impact assessment covering energy, water, grid infrastructure, and household cost impact. Ireland, the Netherlands, and Singapore have all enacted equivalent pauses when their pipelines reached comparable scale. This is prudent governance, not obstruction.

Second, a formal and public Scottish Government opposition to the UK Government’s £24 per megawatt-hour DSIT electricity subsidy, and a refusal to facilitate its application in Scotland. A ministerial statement to the Scottish Parliament, followed by formal correspondence to DSIT, is the minimum required.

Third, a review and update of NPF4 to require Compact compliance as a condition of national development status, delivered through a ministerial direction, Planning Circular, and targeted Policy 24 update – none of which requires primary legislation.

Fourth, a ministerial direction requiring standardised water abstraction and cooling methodology assessments for any application above 50 megawatts, with all results published before the application is determined.

Fifth, the commissioning and publication, within six months, of an independent assessment of the cumulative network cost impact of the current planning pipeline on Scottish household electricity bills. The public deserves to know what is being built in their name and at their expense.

The constitutional reality

Any serious policy proposal must be honest about what Scotland can and cannot do. Electricity market regulation, grid charging methodology, and the DSIT subsidy are reserved to Westminster. But Scotland’s leverage in planning is substantial, largely unused, and time-limited. No data centre gets built without planning permission. Planning is devolved. The conditions attached to planning consent are the Scottish Government’s to set.

Every facility in the current pipeline is still in the planning system. Once consented, the leverage is gone.

A letter worth sending

The Scottish Parliament has 129 MSPs. Every Scottish voter has eight of them – one constituency representative and seven regional list members. Every one of those MSPs can raise a question in the chamber, request a ministerial statement, or write to the Cabinet Secretary demanding a cumulative impact assessment before the next consent is granted.

The template letter at scottishenergycompact.co.uk covers all three environmental grounds documented in this series – water, electricity, and EMF. It is addressed to no party and endorses none. It asks for one thing: that the assessment that should have been done before any of this began is done now, while there is still time for it to matter.

The concrete is not yet dry. Twenty facilities are in the planning system, not yet built. The argument is not yet lost. But the window in which Scotland’s planning powers can shape what gets built, at what cost, and on what terms — that window is closing with every consent that passes without the conditions the Compact requires.

The question is not whether Scotland has the powers to act. It has them. The question is whether the government that claims to act in Scotland’s interest will use them before the opportunity is gone.
