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.

Fitch changes #SizewellC outlook to "negative" from "stable" thanks to #EDF and its subsidiary #Framatome, on which the project relies very heavily (so much for domestic companies doing the heavy lifting)

"#SizewellC is a “terrible deal” for the UK taxpayer.....The public accounts committee said the high level of risk borne by taxpayers and consumers was “extraordinary” while private investors were expected to receive significant returns."

Expressing solidarity with @SEAScampaign S.A.N.D and everyone who worked so hard to stop #SeaLink. Weird that the #EADT would quote Suffolk leaders but not campaigners, while headlining their piece with our joint protest. What gives? #StopSizewellC
