Planning authorities across Scotland have a new job this week. Under a direction that came into force on 17 August, any council receiving an application for a data centre over 50 megawatts has seven days to send Edinburgh a copy of the plans, the site address, and the postcode.

Public Finance Minister Hannah Mary Goodlad signed it off under Regulation 31 of the Town and Country Planning (Development Management Procedure) (Scotland) Regulations 2013, and it applies retrospectively to applications already in the system as well as anything new.

It arrives at the end of a summer in which Scotland’s data centre pipeline went from a niche planning concern to a live political fight. In July, the SNP’s National Council backed calls for a temporary moratorium on new AI data centre developments, sending the question to a government that had, only months earlier, been actively courting the same investment through its AI Strategy 2026-2031 – see Capacity coverage of the freeze threat. Ministers stopped short of that pause. What they’ve done instead is quieter, and for anyone building or financing a facility in Scotland, arguably more consequential.

What the direction actually does

It’s worth being precise about this, because most of the coverage since Sunday has treated the direction as a political gesture rather than a procedural change. Regulation 31 doesn’t give ministers a veto. It doesn’t stop a council granting or refusing an application.

What it creates is central visibility: a running log of every large data centre bid moving through the system, with ministers notified within a week of validation. Goodlad described the aim as supporting oversight of “strategic monitoring of the pipeline of such planning applications and of the implications for wider infrastructure.”

Alongside the direction, she recalled the appeal on a 212MW scheme at 1 Redheughs Avenue in west Edinburgh, on the former Royal Bank of Scotland headquarters site, which councillors had rejected unanimously in February. That decision now sits with ministers rather than council officials. She also ordered environmental impact assessments at sites in Fife and at Wester Hermiston, where the local authority had argued one wasn’t necessary.

Put together, the notification duty and the two interventions signal something closer to selective oversight than blanket restriction. Goodlad framed the balancing act in her statement: “voices of communities that will be affected will be central to any considerations.” For developers with live applications, the practical change is that a decision which might once have stayed at council level can now be pulled upwards, with little warning, on a case the government considers significant.

The definition nobody has written yet

The bigger structural problem sits underneath all of this, and it’s one the direction doesn’t touch. Scotland’s National Planning Framework 4 already classes green data centres as National Development, which should, in theory, fast-track them. But nobody has defined what a green data centre actually is in a way planners can apply consistently.

Colin Lavety, senior planning director at Pegasus Group, put it plainly in a blog post last week: “Scotland lacks guidance on how developers and Local Authorities should apply this status.” He went further, warning that the gap sits awkwardly against Westminster’s separate designation of data centres as Critical National Infrastructure, and that the ambiguity “could deter data centre investment away from Scotland.”

That tension between two governments applying two different frameworks to the same asset class isn’t new to this sector. Capacity has tracked the equivalent fight in England, where ministers reportedly leaned on a council to approve Nscale’s Loughton site over local objections (see our reporting on Britain’s data centre gap and the Nscale delay).

In Scotland’s case, the argument for treating data centres as nationally strategic assets has industry backing too. Sandy Begbie, chief executive of Scottish Financial Enterprise, has argued planning decisions on hyperscale sites should sit above council level given they are “of national importance for economic growth, resilience and security.” The Scottish Greens take the opposite reading of the same facts, warning that unplanned expansion driven by AI demand risks outpacing both the grid and public consent, while still accepting that, in their words, data centres remain “an essential part of modern infrastructure” within limits.

Until Holyrood commits to a working definition of “green,” none of this gets easier. Developers are left designing to a standard nobody has written down, local authorities are left assessing applications against criteria that don’t exist in usable form, and ministers now have a live feed of every application entering that gap.

Where the capital and the grid queue actually sit

The quieter question, and the one that matters most for anyone allocating capital, is whether Regulation 31 changes anything real if the binding constraint isn’t planning at all but grid connection capacity. Scotland’s transmission queue has been a known bottleneck for years, and central notification of planning applications does nothing to move a project up SSEN’s or National Grid ESO’s connection list. A data centre can clear every planning hurdle Edinburgh sets and still wait years for power.

That’s the pattern investors have already been pricing into US markets, where moratoriums in New York and Maine have pushed lenders to treat local and political opposition as a formal credit factor rather than a reputational one, according to Capacity reporting on how banks are pricing community opposition into financing.

New York’s own experience, covered in our piece on who gets caught by the 50MW threshold, shows how a single megawatt cut-off point can redraw an entire market overnight, exempting colocation and enterprise halls while hyperscale campuses take the hit. Assembly member Scott Gray’s line on New York’s own law, that “no one in this chamber wants reckless growth,” from our coverage of the state’s rule change, could sit just as comfortably in Holyrood’s chamber today.

For now, Scotland has chosen visibility over prohibition. Whether that’s enough to hold investment steady while the SNP, the Greens and industry argue over what comes next depends less on what ministers can see in the pipeline, and more on whether the grid, the guidance and the politics catch up with it at the same time.
