Tween Bridge Solar Farm

RWE Renewables submitted the Development Consent Order (DCO) application for Tween Bridge Solar Farm to the Planning Inspectorate (PINS) on 26 August 2025. The application was accepted on 23 September 2025. The application is now in the Pre-Examination stage, during which members of the public, local authorities, and other stakeholders can register as Interested Parties and submit a Relevant Representation to take part in the Examination.

Tween Bridge Solar Farm is located next to RWE’ Renewables’ existing Tween Bridge Wind Farm and adjacent to an existing National Grid 400kv overhead powerline which runs through the site from Drax to Keadby.

We have secured an agreement with National Grid to connect Tween Bridge Solar Farm in the area.

Environmental constraints and land availability then inform the exact location of development within proximity to the identified Point Of Connection (POC).

The UK energy system is dominated by fossil fuels, accounting for c. 76% of energy supply in 2020.  The Government recognises how we need to dramatically increase the volume of energy supplied form low carbon sources and reduce the amount provided by fossil fuels.

The government recognises how solar is a low cost way of generating electricity, and their analysis shows that a secure, reliable, affordable, net zero consistent system in 2050 is likely to be composed of predominantly of wind and solar.

The UK has therefore made a legally binding commitment to achieve net zero carbon emissions by 2050. At the same time, demand for electricity will increase as we decarbonise other sectors of the economy, such as heating and transport.

Solar farms, such as Tween Bridge Solar Farm, will make a significant contribution to the local and national climate commitments.

Tween Bridge Solar Farm comprises a solar farm capable of generating over up to 800MW of Alternating Current (AC) electricity with a co-located 400MW Battery Energy Storage System (“BESS”), enough green electricity to power over 370,000 homes*

* Calculation based on 2021 generation, and assuming average (mean) annual household consumption of 3,509 kWh, based on latest statistics from Department of Energy Security and Net Zero (Subnational Electricity and Gas Consumption Statistics Regional and Local Authority, Great Britain, 2021, Mean domestic electricity consumption (kWh per meter) by country/region, Great Britain, 2021)

Between Wednesday 4 October and Wednesday 29 November 2023, RWE Renewables Solar and Storage Limited carried out a non-statutory consultation with local residents, organisations, and other stakeholders to gather initial feedback on our draft proposals. We are grateful for all the feedback and questions received during this period. All responses were carefully analysed and considered by the project team. A Non-Statutory Consultation Report was prepared to summarise the feedback and outline how the scheme evolved in response. This report can be found here.

A statutory consultation was subsequently held between 20 March and 8 May 2025. The consultation materials built on the earlier non-statutory consultation, incorporating more detailed information and responding to the key themes identified during previous engagement.

The statutory consultation was accompanied by the Preliminary Environmental Impact Report (PEIR), which presented a detailed assessment of the potential environmental effects of the scheme. This comprehensive report covered topics such as ecology, noise and vibration, transport, landscape impacts, and air quality.

The feedback received played a key role in shaping the final Development Consent Order (DCO) application, which was accepted by PINS on 23 September 2025.

The land could simultaneously host both solar power generation and animal husbandry. Tween Bridge Solar Farm could become one of the region’s largest sheep farms, with sheep grazing the fields within the solar farm. An opportunity has also been identified for Tween Bridge Solar Farm to host a bee farm.

Nationally Significant Infrastructure Projects (NSIPs) are major infrastructure developments in England. These include projects such as power plants, large renewable energy projects, new airports, airport extensions and major road projects.

Tween Bridge Solar Farm is classified as an NSIP due to it having a proposed generation capacity exceeding 50MW. We are therefore required to submit an application for development consent to the Planning Inspectorate (PINS). The Secretary of State for Energy Security and Net Zero decides whether to grant consent, in accordance with the Planning Act 2008.

A Development Consent Order (DCO) is the means of obtaining permission for developments categorised as NSIPs. This includes energy, transport, water and waste projects. RWE Renewables submitted a DCO application for Tween Bridge Solar Farm to the Planning Inspectorate (PINS) on 26 August 2025. The application was accepted for examination on 23 September 2025. The application is now subject to a formal examination process led by PINS. This will include opportunities for further stakeholder participation, such as written representations and hearings. After the examination, a recommendation will be made to the Secretary of State for the Department for Energy Security and Net Zero (DESNZ), who will then make the final decision on whether development consent should be granted.

The Planning Inspectorate (PINS) for England is an executive agency of the Department for Levelling Up, Housing and Communities of the United Kingdom Government with responsibility for making decisions and providing recommendations and advice on a range of land use planning-related issues across England.

More information on the DCO process can be found on the Planning Inspectorate’s website.

The proposals for Tween Bridge Solar Farm are a joint agreement with local landowners, many of whom are local farmers seeking to diversify their income.

We want to also reiterate that the land will still be productive with grazing and potential other dual use proposals. These activities, coupled with routine site maintenance will maintain employment on the land throughout the projects 40 year lifespan. Furthermore, unlike other developments (e.g housing), the land can be returned to full agricultural production after decommissioning.

The government has committed to sustained growth in solar capacity to ensure that we are on a pathway that allows us to meet net zero emissions by 2050.  Solar is a key part of the government’s strategy for low-cost decarbonisation of the energy sector.  The British Energy Security Strategy states that government expects a five-fold increase in combined ground and rooftop solar deployment by 2035 (up to 70GW).

Government policy identifies how land type should not be a predominating factor in determining the suitability of sites.  Where sites are located on agricultural land, government is supportive of solar that is co-located with other functions (for example, agriculture, onshore wind generation, or storage) to maximise the efficiency of land use.

At this moment in time it is envisaged that construction will take place through either a single phase or a multiple of phases (i.e., phased approach to the construction of the solar arrays / development parcels).   If all elements were constructed at the same time, then the construction phase would last up to 30 months.

Alternatively, the construction of the Scheme would coincide with the phased connection dates from National Grid. If this route is chosen, construction would occur in two phases, with phase one scheduled for completion in 2029, and phase two completed in 2032.  The Environmental Statement will provide a full description of the potential construction, operational, management and decommissioning variances.

The priority at the scheme will be not producing waste in the first place with priority given to preparing waste for re-use, then recycling, then recovery, and last of all disposal.

All waste arisings transported off site would be delivered to the appropriately licenced receivers of such materials.  Operators receiving any waste arisings would be subject to their own consenting procedures.  It is not possible to forecast the capacity for final disposal for decommissioning at this stage due to potential change in waste regulations and legislation and generation and operators at that time.

The photovoltaic modules will be recycled or reused, where possible. With regards to the supporting structures, the structures will be unscrewed/unbolted, and then removed from the ground using a piling machine. Once the supporting structures have been removed, they will either be re-used or recycled, where possible.

Chapter 10 of the working PEIR identifies the potential impacts on the water environment from construction, operation and decommissioning.  The water environment includes surface waterbodies (e.g. rivers, streams, ditches, canals, lakes and ponds, etc.), groundwater bodies, as well as flood risk and drainage.

The potential impacts on the water environment resulting from the Scheme focus on four main events:

• Erosion/sediment movement.
• Chemical/pollution events.
• Alteration/interruption of surface water flows.
• Alteration/interruption of ground water flows

A surface water drainage strategy will be implemented on site, which will manage the impact of the development on surface water run and  prevent erosion and the discharge of silt-laden runoff from entering surface water drains, watercourses and ponds without treatment (e.g. earth bunds, silt fences, straw bales, or proprietary treatment) under any circumstances.

Surface water runoff from panels, equipment and access tracks will be directed to permeable Sustainable drainage systems (SuDS) features with contributions being made from permeable surfacing, wildflower planting and linear infiltration trenches.

Further surveys will be undertaken and used together with comments received from relevant consultees (e.g Doncaster Internal Drainage Board) to further refine and improve the proposals.

Extensive ecological surveys have been carried out to assess the impact of the proposals on species in the local area. These surveys can be read in detail in the draft PEIR, Chapter 7 – Ecology and Nature Conservation.

Surveys carried out to date include:

• Baseline Habitats Report
• Breeding Bird Survey Report
• Non-breeding Bird Survey Report
• Nightjar Survey Reports
• Badger Survey Report [Circulation of Report is Restricted]
• Otter and Water Vole Survey Report [Circulation of Report is Restricted]
• Great Crested Newt Presence/Absence (eDNA) Survey Report

We are proposing Ecological and biodiversity measures across the entire site area. This includes the potential planting of new hedgerows, bolstering of existing field boundaries to increase coverage of this habitat, provide effective landscape screening, and to improve connectivity of the hedgerow and woodland network across and beyond the limits of the site. These proposals are being developed in conjunction with key environmental consultees.

RWE recognises the use of batteries (including lithium-ion) as Energy Storage Systems (ESS) is a new and emerging practice in the global renewable energy sector. We are consulting with South Yorkshire Fire and Rescue (SYFR) to better understand any risks that may be posed and develop strategies and procedures to mitigate these risks.

To protect the battery energy storage system, it will be equipped with an FFSS (Fire Fighting Suppression System) inside each container. An FFSS includes a smoke detector, control panel, alarm device, exhaust pipe and bump head. It uses a clean fire suppression gas to minimize the second loss. Before gas blow-out, the system controller will send a signal to the HVAC main power switch to stop working as well as isolating the fans and thus achieve fire suppression process.  RWE will continue to monitor developments in technological and regulatory advancements for BESS to ensure that the final design of the BESS complies with any future amendments to fire and safety standards.

Further information can be found in our PEIR: Chapter 16 – Other Environmental Topics.

Investment in the Scheme is likely to create opportunities for local businesses through the supply chain, during the construction process. It is estimated that there will be an average of 176 on-site jobs generated across the Scheme during the construction period, which is estimated to be up to 4.5 years. Once displacement and leakage has been accounted for, the number of net jobs totals 99.

 In total, the Scheme could support 231 temporary jobs, both direct jobs on-site and indirect/induced roles in the wider economy, during the 4.5-year construction period.
