The six-month examination of Lime Down Solar Park in Wiltshire closed on 21st October 2026. The proposed 500-megawatt solar park has moved to the recommendation stage, but the developer, Island Green Power, confirms that no decision on development consent has been made.
The proposal spans five solar photovoltaic sites in north Wiltshire, with battery storage and an underground grid connection towards Melksham substation. Because of its scale, the project is being considered through the national infrastructure consenting process rather than determined as an ordinary planning application by Wiltshire Council.
For neighbours, farmers, landowners and planning professionals, the closure is a meaningful milestone rather than an approval. I would treat it carefully: public hearings and written examination deadlines have ended, but the examining panel must now consider the evidence and advise the Secretary of State, whose decision will determine whether the scheme can proceed.
What the solar park examination actually means
The developer’s current project update confirms that the examination ran from 21st April to 21st October 2026. Before that, Lime Down Solar Park Limited submitted its development consent application on 19th September 2025, and the Planning Inspectorate accepted it for examination on 17th October 2025.
The solar park reached the end of the formal six-month examination period, not the end of the consenting process. The Examining Authority assesses submitted evidence, questions the applicant and interested parties, and produces a reasoned recommendation. It does not grant development consent itself.
A Development Consent Order, usually shortened to DCO, is the statutory route for a nationally significant infrastructure project. The Planning Geek guide to National Policy Statements explains the policy framework used for major infrastructure. This is different from deciding a routine solar installation under local permitted development rules.
The project’s published process timetable says the recommendation normally follows within three months of examination closing, with the Secretary of State normally having a further three months to determine the application. Extensions remain possible, and the developer expects a decision in spring 2027 at the earliest.
What is proposed across north Wiltshire?
The proposed solar park would have a generating capacity of up to 500 megawatts, spread across five solar photovoltaic sites with related electrical, access and landscaping infrastructure. The developer estimates annual electricity generation equivalent to the needs of approximately 115,000 homes. That is a forecast, not a verified measure of electricity already being supplied.
Electricity would travel through an underground connection into the transmission network at Melksham substation. That distinction matters to landowners along the route because construction of buried cables can involve temporary access, excavations and reinstatement even where there are no new overhead pylons.
The plans also include battery energy storage. A battery installation is not simply an extra row of solar panels: its design raises separate questions about equipment layout, safety, access and emergency management. Our guide to battery energy storage planning explains the considerations relevant to these installations.
The applicant has described the solar park as a way to increase domestic renewable generation. However, headline capacity is not the same as continuous output. The actual contribution depends on sunshine, grid arrangements, operation and storage, none of which can be treated as a settled planning benefit without examining the evidence.
What was examined and what did residents say?
The solar park examination brought the developer’s case into contact with objections about landscape character, agricultural land, construction traffic and the cumulative effects on villages in northern Wiltshire. These are not minor details to be resolved merely by saying that more renewable power is desirable.
ITV West Country reported during September’s hearings that Wiltshire Council opposed the proposals and that residents had raised concerns about the scale of the development, roads and the area’s rural character. The council participated in the examination, but it is not the decision-maker for the DCO.
In its 21st October project update, the developer said: “The Examination provided an important opportunity for the proposals to be scrutinised and for interested parties to have their say.” That is the applicant’s account of the procedure, not an independent finding that all impacts have been resolved.
The campaign group Stop Lime Down also confirmed the examination had closed and responded: “The Examination may be over, but the Stop Lime Down campaign is not.” Its position is that the project’s scale and effects warrant refusal. Those objections must be distinguished from an Inspector’s conclusions, which are not yet available.
Landscape, farmland and the limits of mitigation
For the solar park, effects on open views are particularly relevant because the panels, fencing, inverters and other structures could change what people see from roads, paths and nearby homes. Site-specific evidence is needed to judge that effect, not an assumption that all solar schemes cause the same harm or deliver the same benefit.
Our landscape and visual impact assessment guide sets out how viewpoints, landscape sensitivity and effects should be examined. The same discipline matters when discussing proposed planting. Trees and hedges take time to establish, and conditions must be assessed against the likely effects over the development’s life.
Agricultural land is another separate issue. The fact that renewable electricity would be generated does not eliminate questions about soil quality, land use, food production or restoration at the end of operations. Equally, an objection about losing farmland is not by itself a final planning refusal. The decision-maker must assess the competing considerations under the correct national policies.
What happens after the examination closes?
The next step is the Examining Authority’s recommendation report. Interested parties should watch the Planning Inspectorate project record, reference EN010168, for formal updates. The applicant’s public website is useful for project information, but the official case record is the place to verify procedural documents and the eventual decision.
The Secretary of State for Energy Security and Net Zero will decide whether to grant development consent. A favourable recommendation would not itself be the consent. Nor would the closure of the solar park examination tell us that construction is authorised, that every condition has been settled or that the proposed timetable is certain.
If a DCO is granted, the developer would still have to satisfy any applicable requirements before work could begin. If consent is refused, the decision will explain why. Either outcome will have significance beyond this particular project because it will demonstrate how competing energy, landscape, farmland and community considerations were weighed.
For now, the key point is precise: Lime Down Solar Park has completed examination, but remains a proposal awaiting ministerial determination. I would be wary of any headline saying this 500MW solar park has already been approved. The next substantive news event will be publication of the recommendation or the final consent decision, not a repeat of the examination closure.
