A recent consultation issued by the Scottish Government has raised a question that, while technical in form, carries wider implications for how Scotland governs its energy system.
The proposal concerns the threshold at which onshore electricity generation projects are determined at national level under the Electricity Act 1989. At present, developments above 50 megawatts are considered by Scottish Ministers. Below that level, applications are largely handled through local planning authorities.
The consultation proposes increasing this threshold. In practical terms, this would mean that larger projects than is currently the case would move out of ministerial determination and into the hands of local councils.
At first glance, the change appears procedural. It does not alter the nature of the projects themselves, nor does it directly address the wider question of how much energy Scotland should produce or from which sources. Yet it shifts something more fundamental: the point at which authority moves from national oversight to local decision-making.
For those unfamiliar with the system, the threshold functions as a dividing line within the planning framework. Projects above it are treated as matters of national significance, while those below it are considered within local planning processes. Raising that line alters the balance between these two spheres.
The rationale for doing so is tied to the scale and pace of energy development. As Scotland continues to expand onshore generation, particularly in renewable forms, the number and size of applications has increased. A threshold set at 50 megawatts may no longer reflect what is now considered routine. Adjusting it is presented as a way of aligning the system with current conditions.
There are practical consequences to this. Local authorities would assume responsibility for determining a greater number of larger-scale developments. This may allow for decisions to be taken closer to the communities in which projects are situated. It may also introduce greater variation between regions, as different councils apply their own planning judgement.
At the same time, national ministers would consider fewer applications directly. Their role would remain for the largest or most complex developments, but the centre of decision-making would, to some extent, move outward.
This raises a broader question about consistency. A centrally determined system tends to produce a more uniform approach, while local determination reflects the specific character and priorities of each area. Neither model is inherently superior. Each carries its own balance of responsiveness and coherence.
Capacity is another consideration. While planning authorities would receive the formal responsibility for additional applications, the extent to which resources, expertise, and administrative support match that responsibility may vary. The ability to assess large-scale energy proposals requires not only process, but technical and environmental understanding developed over time.
None of these issues are resolved within the consultation itself. They are, however, implied within it. The document is concerned with thresholds and procedures, but the effect of any change would be felt in how decisions are made, where they are made, and by whom.
In that sense, the consultation reflects a quieter shift. Scotland’s energy transition is often discussed in terms of generation targets, technology, and infrastructure. Less attention is given to the structures through which decisions are taken. Yet those structures determine how development is experienced on the ground.
Raising the threshold would not change the landscape overnight. Projects would still be proposed, assessed, and either approved or refused. What would change is the route they take, and the level at which judgement is applied.
For the public, the question is not simply whether more energy should be built, but how decisions about that process are organised. The consultation places that question, in understated form, at the centre of Scotland’s planning system.
