Anyway, it's interesting to indulge in conjecture about why. I don't think we have any real idea. Firstly it may just be that the new Prime Minister wants to have a detailed look at the books before signing it off. Fair enough, but does seem a bit late in the day. We did know the EDF decision was coming a good while back. Couldn't have been a surprise. Personally I don't think the Prime Minister (if it was her decision) was being unreasonable. So much concern about the project (particularly the technology) that it's no surprise she wants to consider it carefully. It seems not even the French are fully sold on the deal. As soon as it emerged that there would be a pause, the shares in EDF jumped skywards.
The media seem to think it's about the involvement of the Chinese - a long term security consideration.
And not so much the £6 billion investment planned for the Hinckley Point project, but subsequent investments in Sizewell and Bradwell. No way we can know if this is true. But if it is, it would mark a big change in attitude towards Chinese investment by the new Prime Minister/Chancellor team from previous regime. The Chinese are reported to be "bemused" and "frustrated". I suspect that's Cinese for absolutely bl*****y furious.
Not really sure where we are now, or what view to take. I had been very much against the UK pulling out of the deal, because of the reputational damage it would do to the UK and to investor confidence. But the French Govt reaction may be a great sign of relief, that a humiliating decision had been taken for it. Since the strike price was agreed EDF has spent £2/3 billion on preparing the site. That's a very big sum to write off.
Anyway we will have to wait and see. What I really do hope is that there is no knock-on negativity impacting on Wylfa B and Moorside.
