Sizewell C – Wrong Project, Wrong Time, Wrong Place.
Stop Sizewell C has been campaigning on the Suffolk-based twin EPR nuclear reactor project since 2013; first as Theberton and Eastbridge Action Group on Sizewell and, since 2019, as Stop Sizewell C. While our initial concern about Sizewell C focused on the impacts of such a large infrastructure project in a singularly unsuited area, we have since 2019 maintained that Sizewell C is the wrong project, at the wrong time, in the wrong place.
-
- Wrong project. In addition to its eye-watering cost – which means its electricity will also be expensive – the EPR reactor has a woeful delivery and operational track record, making it an unreliable energy “solution”. We fully oppose the financing structure of Sizewell C, with a tax – and risk – imposed on households during construction.
- Wrong time. Nuclear gigawatt projects take well over a decade to construct, even without the likely delays with building the EPR, so Sizewell C will not be operational in time to contribute to meaningful target dates to reduce carbon emissions and be a solution to our climate emergency.
- Wrong place. Ironically, coastal nuclear power is vulnerable to the impacts of climate change, and this is a particular concern at Sizewell. Additionally the Sizewell C site is surrounded by protected wildlife habitats and adjoins internationally famous Minsmere and is wholly within the Suffolk Coast & Heaths National Landscape and was opposed by the RSPB and Suffolk Wildlife Trust. Sustainable supplies of drinking-quality water are uncertain and meant the Planning Inspectorate was unable to recommend Sizewell C be granted Planning Consent.
Stop Sizewell C has published a report “Sizewell C, the Unanswered Questions” which draws together what is known, what it is impossible to know, and what the government continues to keep secret about Sizewell C.

"When [will] #SizewellC be finished? Govt seems determined to keep this secret. Locals need to know how long this nightmare is going on for. The British public needs to know how long they have to pay for it until they get any electricity"

So how does the government feel about the billions it ploughed into #SizewellC now?
#StopSizewellC
It's one year since the #PrimeMinister came to #Suffolk and splashed >£14bn of taxpayers' cash on #SizewellC. READ our new report "Sizewell C: the Unanswered Questions" and about the secrecy, obfuscation and deception related to this project
