No. The entire Rosefield site is 675 hectares (approx. 1,665 acres). We expect to use around 40% (280 hectares / 691 acres) of that for above ground development. The rest of the site would be used for areas of underground cabling and access, and areas of landscape and ecological enhancements.

We recognise that there has been a significant volume of construction in the area due to HS2 and East-West Rail.

In response to feedback about the current and potential future effects of construction on the local area, we have submitted an Outline Construction Traffic Management Plan as part of the DCO Application, which details our approach to managing construction traffic effects. 

We oppose the abuse of human rights and forced labour anywhere in the global supply chain. We ask all suppliers to ensure compliance with the Modern Slavery Act and we are also actively strengthening our existing procurement process to make every effort to prevent any negative impact on people and the environment.

We support applying the highest possible levels of transparency and sustainability throughout the value chain and commit to the development of an industry-led traceability protocol to help ensure our supply chain is free of human rights abuses.

We have not yet started the procurement process for Rosefield Solar Farm. This process would begin should Rosefield Solar Farm be granted consent. As part of this process, we would determine the most appropriate suppliers at the time.

Protecting the amenity of local footpaths and creating new routes has informed our proposals.

As part of the proposals, we have included the creation of three new permissive footpaths to provide inclusive access to new locations around the Site, while connecting the existing network of promoted walks, cycleways and bridleways. This is detailed in the Design Approach Document which forms part of the DCO Application.

We have also identified stretches of five PRoW to be diverted. These diversions would be to better connect the local network of piecemeal PRoWs whilst also minimising the extent to which PRoWs interact with the Proposed Development. Where PRoW are proposed to be diverted the Applicant has ensured that the routes would be enjoyable, provide enhanced links to the surrounding PRoW network where applicable and would not result in lengthy additions to the PRoW.

We are also considering opportunities for improving wayfinding and installing heritage information panels to help people learn about the local landscape and history of the area.

To protect the amenity of the public rights of way running from Botolph Claydon and around the existing woodlands, we are proposing a 55m wide green corridor along Bernwood Jubilee Way. A mix of grasses and wildflowers is also proposed to boost biodiversity along this route. The Mid Shires Way and North Bucks Way would have an offset of 30m from the proposed Solar PV development.

Views of Rosefield from public and private locations – including nearby homes, villages, roads and footpaths – have been an important consideration in the design process for Rosefield. The Design Approach Document submitted as part of the DCO Application sets out how Rosefield has been designed to reduce visual effects from homes, villages, roads and footpaths. 

A full assessment of ecological receptors is presented within the Environmental Statement (see Chapter 7: Biodiversity) which forms part of the DCO Application.

Given the sensitivity of the location of the Proposed Development, particularly to commuting and foraging bats, the layout has been deliberately designed to ensure the retention, creation and enhancement of habitats such as field margins, woodland, hedgerows, trees, ponds, watercourses and ditches through appropriate buffers. Along with retaining existing habitats wherever possible, the locations of mitigation areas have been chosen to ensure the connections between the existing SSSIs and ancient woodland adjacent to the Site would be enhanced.

By creating species-rich grassland and arable margins along with scrub and tree planting, this would create a coherent ecological network linking the Site to the wider landscape, supporting the movement of local wildlife, particularly bats. The creation of species-rich grassland would provide ground-nesting bird habitat suitable to support skylark and create a nectar source for invertebrates, which in turn provides a foraging resource for bats and bird species. A mosaic of scrub and grassland would improve foraging habitat for bats and provide habitat to support invertebrates. Restoration of defunct ponds would help to enhance the pond network in the area, provide additional bat foraging habitat and support great crested newts.

In addition, these habitats would also be of benefit to species including invertebrates, amphibians, reptiles, non-ground nesting birds, roosting bats, badger, otter, harvest mice, bank voles and deer. Buffer zone between fences and hedgerows/field margins would also allow animals such as deer to disperse along the buffer through the wider landscape.

A detailed biodiversity design has been developed which identifies how a net gain in biodiversity would be achieved in accordance with the Environment Act 2021 and NPPF, using the most up to date Defra Statutory metric (see the Biodiversity Net Gain Assessment which forms part of the DCO Application). On a precautionary basis, we are committing to a minimum net gain of 40% area habitat units, 17% hedgerow units and 10% watercourse units.

Yes. Battery storage technology is safe and makes use of tried and tested technology, much of which we use in our day-to-day lives, such as electric cars.

While battery storage at Rosefield would be larger in scale, we would build safety measures into our battery design, including, for example, self-contained units for each battery. This is something EDF power solutions does at the battery storage sites it manages around the country.

We are working with Buckinghamshire Fire and Rescue, along with other relevant statutory bodies as we develop proposals for Rosefield. Their feedback to date has fed into our updated proposals, including an Outline Battery Safety Management Plan which forms part of the DCO Application. We will continue to engage with them throughout the DCO process.

Solar farms need to connect into the National Grid to supply the electricity they generate to homes and businesses. We have secured a 500MW grid connection agreement with National Grid at East Claydon Substation. There would also be capacity to import power from the network.

The East Claydon Substation, which was originally built in the 1960s, is coming towards the end of its useful life. It also needs to be replaced to meet National Grid’s commitments to new connections at this location (of which Rosefield’s connection would be less than 10% of the proposed capacity).

At this stage, we do not anticipate that National Grid’s proposal to replace the substation would impact the timescales of our Development Consent Order (DCO). We have submitted our DCO in October 2025. We will continue to work with National Grid throughout this process.

No. We are aware of separate proposals for battery storage in the local area. These are standalone projects that do not form part of our proposals for Rosefield Solar Farm.

Other battery storage projects in the area have separate grid connection agreements with National Grid and are being developed separately.

Where information about projects is publicly available, these will be included in our cumulative assessment.
