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.

WHAT YOU CAN DO.

Good to see #Leiston business owners speaking out about the impacts of #SizewellC: "Leiston high street is facing a crisis as Sizewell C roadworks, low footfall and high costs pile on the pressure"

Has to be said, consideration for locals is not a strong point: "#SizewellC workers blasted for parking in Leiston. Sizewell C workers have been accused of leaving their cars in disabled spaces and clogging side roads...."

As @Keir_Starmer reflects on his legacy, one decision that we predict WON'T stand the test of time is #SizewellC. Will @AndyBurnhamGM grasp the mettle and reconsider this multi-billion pound/bill-raising mistake? He's all about change....
#StopSizewellC

More evidence from #Somerset of the shape of things to come here in #Suffolk with #SizewellC: "We've Lost Everything.......Life in Combwich - with no shop, bus and a pub that's a [#HinkleyC worker] HMO" (House of Multiple Occupancy)"

"Upset over [#SizewellC] road closure on busy festival weekend". The irony of this is that #SizewellC is a sponsor of/collaborator with the #FirstLightFestival. Something of an own goal to be closing the #A12 this weekend then...

Two sides to the same story, but fish are NOT the main reason #HinkleyC is scheduled to take at least five years longer than forecast!
"#Nuclear plant could be delayed again by demands to protect fish"
