Sizewell C

The Government is proposing to build a new nuclear power station at Sizewell. I am working hard to make sure that Suffolk Coastal reaps the benefits this opportunity will bring in terms of new high skilled jobs, education opportunities and infrastructure investment.

I sit on the Joint Local Authority Group (JLAG) and the Sizewell Stakeholders Group (SSG). These are designed to make sure that local people's voices are taken into account when considering the construction phase of the project and the legacy it will bring.

Sizewell C - Therese's Response to the Third Stage of Consultation

This is my response to the Stage 3 consultation for Sizewell C as the Member of Parliament for Suffolk Coastal and local resident.

The construction of Sizewell C is extremely important for the UK's future energy supply and will benefit the local community here in Suffolk, with the creation of thousands of jobs including well-paid, long term jobs. That is very important for local prosperity given the very low average income in this part of Suffolk. That said, I recognise that many people have moved or retired here to enjoy the very special nature and environment of the Suffolk coast and will not have experienced the construction of Sizewell B. I fully understand their concerns that a new nuclear power plant at Sizewell will create significant disruption to local communities and the transport network, especially during the construction phase. Mitigation against these impacts is key. There have been some significant changes from Stage 2 consultation, though not all of my concerns that I expressed in the Stage 2 consultation have been addressed. I have attended the Sizewell C Community Forum. I continue to participate in the Joint Local Authority Group as an observer. The councils have submitted and published their responses separately.


The marine-led option from Stage 2 is discarded. Their environmental assessment excludes the jetty, though there will still need to be a beach landing facility. I think that is regrettable and we certainly need more information on why it has been discarded. This leaves a rail-led and road-led strategy. Both provide certain transport mitigations, namely a 2-village by-pass for Stratford St Andrew and Farnham, a by-pass south of Theberton, park and ride facilities at Darsham and Wickham Market and a new roundabout at Yoxford. If the road-led strategy is chosen, further traffic mitigations include a new Sizewell link road from the A12 between Saxmundham and Yoxford, bypassing Middleton Moor and Theberton and a link from the B1122 down to the new road. There will also be freight management centres on the A14 near Seven Hills or Innocence Farm. If the rail-led strategy is chosen, a new branch line from Leiston into the construction site would be built to carry the extra 5 freight trains a day needed along with a new level crossing on the B1122. 12 level crossings would be closed and rights of way diverted. I understand English Heritage are more comfortable with this option. The new branch line and level crossing to facilitate it would be removed after the construction phase is finished.

EDF need to justify why the marine-led option has been eliminated. Of what remains in the consultation, my preference is for the rail-led strategy. I understand it requires Network Rail to provide significant upgrades on the East Suffolk line and I beleive that possible. The lasting legacy is less impacting with rail-led provision. EDF has highlighted the risk of this strategy is that it would not be entirely in their control as it would depend on Network Rail. I have met the Rail Minister and Network Rail on this matter. The Traffic Works Order can take time to secure but it can also be included in the planning application. In any event, I want to see further improvements along the A12, particularly at the roundabout by Seckford Hall and possibly making that stretch of the A12 dual carriageway (with a reduced speed limit of perhaps 50mph). Seven Hills roundabout will also need enhancing.

I have had significant representation from residents about the road-led strategy being undesirable, especially regarding the link road and the increased number of lorry movements. I agree.


I understand concerns remain regarding the proposed site for the accommodation campus at Eastbridge. I have previously asked EDF to find different sites and I understand the local council have been unable to find viable alternatives. I do recognise that EDF have made improvements and the car park will be closest to the village. The accommodation itself will be reduced to a maximum height of 4 floors, with the tallest buildings closes to the reactor site. A housing and tourism impact fund is suggested. Details are to be worked through with the local council. An accommodation office for workers will help guide them to EDF provided site as well as longer-term housing options. I have spoken to residents and attended a Theberton and Eastbridge Action Group on Sizewell exhibition and appreciate that whilst other sites would be preferred, with none forthcoming, further mitigation could be done. I think several suggestions are well thought through, including measures to reduce light pollution.

The leisure facilities in Leiston, adjacent to the Leisure Centre and Alde Valley School, will be kept as a lasting legacy for the community, these will include 1-2 multi-use games areas and a synthetic 3G football pitch. Other aspects of community mitigation have yet to be discussed with the councils. There is ongoing work regarding skills and employment in partnership with the councils, LEP and business organisations. More detail is still needed on the environmental aspect, especially regarding new pylons on the site itself. These new pylons concern me. EDF should provide the analysis on why the alternative solution is not viable. I should state though that Sizewell A was created before the AONB was created and I accept the nuclear cluster approach which the government has taken.

What is not addressed in this consultation is the cumulative impact of a number of energy projects. I have recently submitted a response to the consultation on SPR infrastructure projects. These risk significant damage to the natural environment and need to be considered in the round.

Sizewell C - Third Stage of Consultation

The third stage of public consultation on Sizewell C is now open. There have been quite a few changes since the last round of consultation so I would encourage you to read and reply to the consultation document which closes on the 29th March.

EDF is also holding a series of public exhibitions across eastern Suffolk throughout January. Details of which can be found here.

I attended their public exhibition in Saxmundham last weekend and I'm currently formulating my early thoughts, which I will share shortly with residents before I reply formally to the consultation.

Sizewell C - Therese's Response to the Second Stage of Consultation

EDF's stage 2 consultation for the construction of Sizewell C came to end on the 3rd February 2017 and I responded with my views.

My full response to the consultation is set out below:

Sizewell C Stage 2 Consultation Response

The construction of Sizewell C is extremely important for the UK's future energy supply and will benefit the local economy here in Suffolk, with the creation of thousands of jobs. That said, a new nuclear power plant at Sizewell will create significant disruption to local communities and the transport network, especially during the construction phase. It is essential that these impacts are mitigated as much as possible and it is in this context I respond to EDF's proposals at Stage 2 consultation.


I recognise that we have had a nuclear power plant on the AONB at Sizewell for 60 years and EDF have an admirable record of environmental management. More information is required and I would expect a draft Environmental Impact Assessment to be submitted at Stage 3.


Recognising the GDA process limits changes to key nuclear components, the elements that can be adjusted should be made as aesthetically pleasing as possible to fit in the local environment. Unnecessary light pollution should be avoided.


Construction Material

I want to see as much construction material come in by sea and rail as possible rather than putting more pressure on our road network. The potential of both sea and rail methods of transport need to be maximised rather than one or the other.


I support the building of a jetty that can facilitate the maximum amount of construction material coming in by sea but that does the least amount of damage to the environment. I think there is a case for the wide jetty but it isn't clear what impact it will have on coastal defences and if it does, how EDF will mitigate that. More information is required on this element.


I support the temporary extension of the Sax-Leiston branch line – the green route – to bring material to the site.

Farnham Bend

EDF's options 1, 2 and 3 are unacceptable. Option 1 suggesting no change, isn't an option at all. Option 2 and Option 3, the road widening and a one village bypass just for Farnham isn't acceptable. Option 4, a two village bypass for Farnham and Stratford St Andrew is the minimum mitigation required. A business case is being worked up for a 4 village bypass, as part of the full Suffolk Energy Gateway, a proposal EDF should consider in conjunction with Suffolk County Council as part of the Stage 3 consultation.


None of the proposals are adequate to mitigate the huge increase in traffic that will take place along the B1122. If EDF is to proceed with B1122 options, by passes should be considered. EDF should set out in detail, whilst recognising the national planning policy statement, why options explored for Sizewell B, namely the D2 route, haven't been investigated for Sizewell C.

A12 turnoff at Yoxford

This particular issue needs considerably more work by EDF. It is not evidenced that either option, the signalised junction or roundabout, will solve the problem. It was previously suggested that a double roundabout would be feasible without demolition of houses there.

Further Highway Improvements

The construction of Sizewell C will have a much wider impact on the road network than just those set out in the consultation. The impact further down the A12 and the A14 needs to be assessed and potential mitigation measures worked up.

The A12 should be dualled both ways between the Seckford roundabout, the junction with the B1438 and the Wyevale roundabout, the junction with the B1079.

I am also concerned about the capacity of the Seven Hills roundabout at the A14 junction and the Woods Lane roundabout at the junction with the A1152, which need assessing.

Park & Ride

I support both the park & ride sites at Darsham and Wickham Market as set out in the consultation. I don't support the reserve site at Woodbridge and would not support that being taken forward if the Wickham Market site is dropped.

Accommodation Campus

I do not support either options 1 or 2, which both put forward a single accommodation campus site at Eastbridge in the Area of Outstanding Natural Beauty. EDF have yet to provide a compelling reason why the accommodation campus for Sizewell should be different to Hinkley, which is not next to the construction site. There are opportunities within 15 minutes of Sizewell which have not been explored. I would therefore like EDF to conduct a full appraisal of alternative sites prior to Stage 3 consultation.

I agree with the proposal that sports facilities should be located in Leiston to provide a legacy benefit for the local community.

EDF 1ST Round Proposals

This is the text of a letter that Therese sent to constituents that gives her initial thoughts on most of the EDF proposals.

This consultation does not refer specifically to the creation of a nuclear power station or its safety. The Office for Nuclear Regulation (ONR) has given its approval to the design proposed by EDF and its supplier Areva. The ONR will grant a site licence and is responsible for assuring safety.


Sizewell B design is iconic. Sizewell C should be of a similar appearance with cosmetic changes as appropriate rather than changing fundamental design of the reactor.

Accommodation site(s)

EDF wants to build something like halls of residence or a group of Travelodge-style accommodation with on-site catering and sports facilities. It wants just 1 campus of 2-3000 bed spaces.

I oppose sites 1 and 2. Site 3 could be changed to bring the accommodation blocks closer to the main road. This would provide the infrastructure (water, gas, broadband, etc.) for new housing on that site in the future. Perhaps this site should be capped at a certain number of bed spaces and an additional accommodation site should be considered elsewhere in the district. The site close to the A12 in Saxmundham has been suggested.

Park and Ride / Lorry Management

North: We need more information but the only realistic site of these is Option 2. This will leave a legacy option next to the rail station. Option 1 on the B1122 is completely out of the question, due to the already constrained junction with the A12. Option 3 (by Little Chef) is too close to A144 junction.

South: In any event, no freight consolidation should be done there but at a site by Option 3 is too close to dangerous junction. The Wickham Market Option 1 could work but still has a lot of traffic going up the A12 with single carriageway. Most likely is Option 2 by Woodbridge. This would leave no legacy benefit as it is not appropriate to have mass building west of the A12. However, the pull on/pull off needs to be modified to prevent backups at the roundabout. The Seckford Hall roundabout should be improved with a filter lane to allow free-flowing traffic.

Freight: I have concerns about all the sites. Congestion on the A14 and by Seven Hills is already a concern. With some modifications, Orwell East or West could work. I had thought the Orwell sites would be ruled out but they are the preference, so far, of the County and Emergency Services.


I think the blue route provides least technical issues and takes material straight into site.


None of the options for the A12 address the full issues. The 1 village bypass solves the Farnham bend at first sight but cuts right through local amenity land. Without any other option presented by EDF, the only credible alternative is a 4 villages bypass. EDF needs to present more data.

The impact on residents along the B1122 and at the turnoff of the A12 will be highly significant, compared to everyday traffic. I have long thought an alternative road is needed, though that sentiment is not universally shared. In any event, significant improvements to the road and pathways, perhaps combined with double glazing for all houses and speed limiters. The route from the Southern Park and Ride is not finalised and alternative routes could be considered rather than the B1122. On visiting the A12 turnoff, it was thought a double roundabout by Yoxford would be feasible without demolition of houses there. This particular issue needs considerably more work by EDF and the County Council.

Sizewell C Consultation

The first stage of consultation for Sizewell C has now opened and will run until 6th February 2013. I urge you to have a look at the document and respond with your views here.

I believe the construction of Sizewell C will create thousands of jobs and will provide a massive boost the local economy. I met the County Council's lead officers on skills and education to press the importance of how we must ensure young people and existing workforce are equipped to take advantage of these opportunities. Suffolk Chamber of Commerce is already coordinating business efforts through its supplier microsite. However, with construction comes significant disruption including traffic and housing. Leiston residents have a key choice to make concerning whether the temporary housing could actually be developed into future housing. We need the best engineeering on the jetty to avoid coastal erosion. The rail loop and track may have legacy benefits. On roads, I know residents in the 4 villages will be disappointed that only a Farnham bend by-pass was proposed but this is early days in the marathon negotiation. I have particular concerns on the A12/B1122 turnoff and impact on the villages of Middleton Moor and Theberton. It is important that Suffolk residents benefit as much as possible from Sizewell C, including maximising improvements to infrastructure. So have your say.
