Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision Site visit made on 24 July 2025 by T Gethin BA (Hons), MSc, MRTPI an Inspector appointed by the Secretary of State Decision date: 19th August 2025 Appeal Ref: APP/D0840/W/24/3358031 Land North of Canworthy Water, Canworthy Water, Launceston PL15 8UB • The appeal is made under section 78 of the Town and Country Planning Act 1990 (as amended) against a refusal to grant planning permission. • The appeal is made by Windel Solar 4 Ltd against the decision of Cornwall Council. • The application Ref is PA23/04306. • The development proposed is Development comprising the delivery of a ground mounted solar farm alongside associated infrastructure including distribution substation upgrades with the capacity to deliver approximately 42MW of renewable energy. Decision 1.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision The appeal is allowed and planning permission is granted for development comprising the delivery of a ground mounted solar farm alongside associated infrastructure including distribution substation upgrades with the capacity to deliver approximately 42MW of renewable energy at Land North of Canworthy Water, Canworthy Water, Launceston PL15 8UB in accordance with the terms of the application, Ref PA23/04306, and subject to the conditions set out in the schedule to this decision. Application for costs 2. An application for costs was made by Windel Solar 4 Ltd against Cornwall Council. This application is the subject of a separate Decision. Preliminary Matters 3. An amended site layout plan and amended landscape and ecological masterplan were submitted with the appeal. Amongst other aspects, these include additional hedgerow planting in various parts of the appeal site, minor amendments to the position of solar panels across the site, some changes to on-site access tracks and fencing, and the removal of some solar panels from areas with high archaeological sensitivity.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision To account for the proposed amendments, some reports and other documents were updated/revised (including, for example, photomontages from the Landscape and Visual Impact Assessment) and some additional technical notes/statements were also supplied. 4. The amended plans and updated/additional documents clearly include some changes and additions compared to the scheme that was considered by the Council and by interested parties at the application stage. However, the amendments proposed to the scheme are not so significant that they would fundamentally change the development proposed or result in a substantial difference from that originally applied for. The available evidence also indicates that the findings of the Environmental Statement remain valid whilst the submitted statement of common ground confirms that the Council has no concerns with the https://www.gov.uk/planning-inspectorate

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision Appeal Decision APP/D0840/W/24/3358031 amended plans being considered as part of the appeal. Accordingly, considering the appeal with regards to the amended plans and additional details would neither cause procedural unfairness nor prejudice third parties’ interests, and I have determined the appeal on this basis. Main Issue 5. The main issue is the effect of the proposed development on the character and appearance of the surrounding landscape. Reasons 6. Covering some 82 hectares, the appeal site encompasses a relatively large area. Containing numerous pasture fields bound by extensive hedges and including some trees, the site positively contributes to the agricultural character and verdant appearance of its rural landscape setting. Although the site is within Cornwall Character Areas CCA39 (Upper Tamar and Ottery Valleys) and CCA38 (Western Culm Plateau), the majority site is within the latter with only a tiny part in CCA39. On this basis, the landscape of the Western Culm Plateau is clearly most relevant, although as CCA38 covers a relatively large area with a variety of features, some of its valued attributes are not relevant to the site and the landscape in which it is set.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision However, the relevant attributes and characteristics include the traditional pastoral use; the historical small-scale field pattern bound by the important landscape features of Cornish hedges (with trees); and the sense of openness from the exposed plateau, with the contrast between its simple landform and complex local details identified as providing special interest. The site’s situation (which is also identified as being entirely within Landscape Character Type D: Downs) and form broadly reflect this. 7. Despite its size, public views of the site are limited by topography and the numerous hedgerows on the site and in the locality. These aspects, combined with its extensive nature, also mean that not all of the site can be seen at once. Nevertheless, parts of it are clearly visible from some points in the surrounding area. This includes in both short and medium-longer distance views, such as from the existing field access at viewpoint (VP) 2, from the public right of way in the vicinity of VP6 and from Warbstow Bury (VP10).

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision I observed on my visit that parts of the site are also visible to some extent via, for example, glimpses through field openings and above hedges from (and near) the highway leading north-west from Canworthy Water; and from the public rights of way in the vicinity of VP4 and VP5. 8. Various site features such as hedges, trees, watercourses, culm grassland and the field pattern would not be adversely affected by the proposed development, and much of the site could continue to be grazed. However, whilst the development would not cover the entire site, the proposal would result in a significant change to its character overall due to its adverse effect on land cover. Nevertheless, the visual change in the vicinity of the site would be limited due to topography and soft landscaping screening much of the development. With additional planting being provided and existing hedges and trees being allowed to grow, some important landscape aspects of the site’s character would be enhanced, whilst some historic field boundaries would also be reintroduced/replicated.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision In addition, taking account of panel positions and planting (existing and proposed), the short distance view through the opening into field 18 (at VP2) would essentially be restricted to a glimpse of a small part of the development. https://www.gov.uk/planning-inspectorate 2

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision Appeal Decision APP/D0840/W/24/3358031 9. Most other public views with clear visibility of the proposed development would involve generally longer distance vistas in which the wider, open, undulating landscape would be experienced. In addition, the development would be broken up by existing and additional planting and not all of it could be seen in one view. Furthermore, it would read as largely recessive in the wider landscape due to the site’s relatively low-lying position and, amongst other aspects, the low profile of the solar panels. The site and locality also include various electrical infrastructure, such as pylons, a sub-station and the neighbouring 25 megawatt solar farm. 10. The development proposed would therefore neither appear as a wholly incongruous or particularly notable feature in the locality. Despite the presence of other solar farms in the surrounding area and further afield, neither would it result in solar farms becoming a dominating land use or defining characteristic of either the local or wider landscape. It would also not significantly adversely affect the valued attributes of the relevant landscape character areas and types. 11.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision Nonetheless, the appeal proposal would read as a modern, industrialising feature covering a relatively large area of largely undeveloped, pastoral countryside. When seen in-combination with the existing neighbouring solar farm, which the evidence indicates would be in several views, it would also appear as a more prominent element within the local area. This directly relates to the identified pressures of the character areas which include, amongst other aspects, the introduction of renewable energy development impacting on the rural agricultural landscape and such development becoming more prominent and increasingly prevalent within the farmed landscape. 12. Taking all of the above into account, the development proposed would overall therefore have a moderate adverse effect on the character and appearance of the surrounding landscape. That the development may appear as a minor extension to the adjacent solar farm in some views and that the area is identified by the Council as being of medium-high/high sensitivity to solar developments do not lead me to a different conclusion.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision In coming to this view, I have also taken into account its temporary, reversible nature; that new planting would take some time to mature; the landscape is neither locally or nationally designated nor defined as a valued landscape; and that the adjacent solar farm has been identified by the Council’s landscape sensitivity assessment as being well-integrated into the landscape. 13. In addition, there is a reasonable degree of separation to the other nearest solar farms that my attention has been drawn to. The available evidence also indicates that opportunities to see the proposed development in the same view as any of those would be very limited given the undulating topography for example; and the landscape in which the proposed development would be seen would have neither an obviously nor unacceptably high number of similar developments. 14. Nevertheless, for the above reasons, I conclude that the proposed development would harm the character and appearance of the surrounding landscape. I therefore find that it conflicts with Policies 2 and 23 of the Cornwall Local Plan Strategic Policies 2010 - 2030 (CLP).

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision Amongst other aspects, these expect proposals to respect and enhance quality of place and sustain local distinctiveness and character. 15. However, as I have found that the appeal proposal would have a moderate adverse effect, and planting would further mitigate the development’s effect on the https://www.gov.uk/planning-inspectorate 3

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision Appeal Decision APP/D0840/W/24/3358031 landscape, I find no conflict with Policy RE1 of the Climate Emergency Development Plan Document (DPD) in relation to this matter. This is because the policy supports renewable energy proposals where, amongst other aspects, there would be no significant adverse impacts on the local environment that cannot be satisfactorily mitigated. Whilst the Council also alleges a conflict with CLP Policy 1, my attention has not been drawn to any words in it that are relevant to this issue. The policy has therefore not been determinative in my decision. Other matters 16. Although there are no designated heritage assets within the site, there are various such assets, including listed buildings and scheduled monuments, in the surrounding area. However, the Council does not allege that the proposal would harm any designated heritage assets and have agreed that the proposal would result in no harm through change to the setting of any such assets. Having considered the development and visited the site, I have no reason to find otherwise.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision With the amended plans avoiding development of the site’s most archaeologically sensitive areas, combined with archaeology-related conditions, there would also be no harm to non-designated heritage assets. 17. A number of other matters have been raised by various parties and I have taken them all into account.

A number of other matters have been raised by various parties and I have taken them all into account.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision This includes: the need for solar energy, its level of efficiency (including in comparison to offshore wind), where the electricity that is produced would be used and the need for back-up sources of power; consideration of alternative sites (including using brownfield sites and installing panels on existing roofs and new buildings); where the panels would be made and how environmental/sustainable they are; flood risk and drainage issues; loss of farmland and the production of food and silage; the impact on the price of land, with tenant farmers being driven out; highway safety, damage and congestion issues, particularly with regard to access via the narrow rural lanes, a bridge and un-made track; connection to the electricity network versus battery storage; the extent of the appellant’s community consultation exercise and the Council’s consultation on the planning application; the time needed for residents to review the submitted documents, some of which are alleged to be misleading; the proposed plans showing typical rather than actual/final designs; harm to wildlife; pollution; the effect on the living conditions of neighbouring occupiers, including with regards to noise and light pollution, glint and glare, health

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision risks (including from exposure to electromagnetic fields), overlooking/loss of privacy, inconvenience from construction works, and outlook; the proximity of the site to existing properties in Canworthy meaning that the houses that look on to the site would have clear views of the proposed solar panels/farm; the use of water to clean the panels and the need for rainwater harvesting; harm to tourism and the area’s tranquillity; lack of specific local benefits, with the profit not being kept in the county/country; the proposal would be seen as an addition to the existing neighbouring solar farm, which is said to be (one of) the largest in Cornwall, with the panels combining to appear as one large mass of glass; the impact on dark sky reserves; the 40 year lifespan not equating to a temporary development; a previous application for a wind farm on the site being refused; and the local community, the parish councils and Cornwall Council not wanting the scheme.

Consequently, they do not lead me to a different overall conclusion that the appeal should be allowed. Some of the issues raised, such as regarding construction works, light pollution, final design details and wildlife protection/enhancement can also be covered by planning conditions. Planning Balance 19. Inconsistent with the provisions in the National Planning Policy Framework (Framework) which seek to conserve and enhance the natural environment, the proposed development would harm the character and appearance of the site and surrounding landscape. Whilst this attracts significant weight, and I recognise that the countryside is of great import to people who live and holiday in the area, I have found that the overall harm to the landscape would be moderate rather than significant. Nevertheless, the conflict I have identified with development plan policies in relation to this matter leads me to conclude that the appeal proposal, despite its accordance with various other CLP and DPD policies (and parts of others), conflicts with the development plan as a whole. 20.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision However, the proposed development would provide various benefits. This includes the generation of approximately 42 megawatts of renewable energy, estimated to offset more than 15,693 tonnes of CO2 emissions per year and meet the electrical needs of over 11,655 homes. 21. The proposal would therefore reduce the UK’s dependence on fossil fuels and support the decarbonisation of the electricity network and the move towards a low carbon future. Consistent with the Framework’s provisions on planning for climate change, this is critical to meeting commitments on renewable energy and carbon emissions, and the need to achieve net zero. 22. As agreed by the main parties, the proposed development would also make a valuable contribution towards addressing climate change and meeting national and local renewable energy targets. This includes, for example, the national target of delivering 45-47 gigawatts of solar power by 2030 and Cornwall’s target of 100% renewable electricity supply by the same date. 23. The submitted evidence indicates that significant deployment at an accelerated pace is required to meet these.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision The provision of other schemes already providing sources of renewable energy in the county does not change this, particularly given the available evidence identifies that less than half of Cornwall’s electricity is currently provided by such sources. 24. By increasing domestic energy supply and thus contributing towards UK energy security, the appeal proposal would also provide resilience in times of high (and ever-increasing) demand and, over time, assist to stabilise energy prices. In addition, the proposed development would provide additional employment; deliver significant biodiversity net gain; and support farm diversification (without using best and most versatile agricultural land), whilst also allowing the site to continue being used for agricultural purposes, such as sheep grazing. 25. These environmental, social and economic benefits are extensive and attract significant weight. With a secured grid connection available from June 2026, they could also be delivered quickly. Accordingly, I judge that the scheme’s benefits would be substantial and are sufficient to outweigh the moderate landscape harm. https://www.gov.uk/planning-inspectorate 5

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision Appeal Decision APP/D0840/W/24/3358031 Despite the harm I have identified, I therefore find that the local environmental impact of the proposal is also acceptable in this instance. Conditions 26. I have had regard to the various suggested planning conditions and considered them against the tests in the Framework and the advice in the Planning Practice Guidance. I have made such amendments as necessary to comply with those documents, for clarity and consistency, and to ensure that details are submitted for the Council’s approval where relevant. 27. In addition to the standard time limit condition, I have imposed a condition requiring the carrying out of the development in accordance with the approved plans in the interests of certainty. A condition setting out the time limit for the operational period of the solar farm and its subsequent decommissioning and restoration is necessary in the interests of agriculture, landscape character and archaeology. 28. Given the site’s position and the extent of development, pre-commencement conditions 4 and 5 are necessary and reasonable in the interests of the biodiversity, landscape, the environment and the living conditions of residents.

Land North of Canworthy Water, Canworthy Water, Launceston, PL15 8UB — Cornwall Council — Appeal Decision Pre-commencement conditions 6 and 7 are necessary given the site’s archaeological sensitivity and significance. Pre-commencement condition 8 is necessary in the interests of flooding and controlling surface water pollution. 29. Conditions 9, 10 and 11 are necessary in the interests of, respectively, the landscape, biodiversity and the safe and efficient operation of the highway. In the interests of the living conditions of residents, and having regard to the Planning Committee’s discussions, I have also added reference to the provision of any external lighting within condition 9. Conclusion 30. Planning law requires that applications for planning permission be determined in accordance with the development plan unless material considerations indicate otherwise. In this instance, the appeal proposal’s benefits outweigh the harm that would arise, the conflict with development plan policies and the Framework. Consequently, material considerations indicate that the proposed development should be permitted notwithstanding the conflict with the development plan as a whole. 31. For the above reasons, the appeal is therefore allowed.
