Cost of Miliband's nuclear plant doubles to more than £40bn
The cost of the Sizewell C nuclear power plant has doubled to more than £40bn as ministers race to strike a funding deal with private investors and the French government.
An official cost estimate for the scheme in Suffolk, which would generate enough electricity for 6m homes, was previously put at £20bn.
But that has grown to £30bn at constant prices – or £41bn in today's money – with the Government set to shoulder at least half of the upfront cost, according to industry and Whitehall sources.
The entire scheme will ultimately be paid for by households and businesses via their electricity bills, including through levies that will begin during construction.
The power plant's rising price tag will trigger concerns about future increases as Hinkley Point C, a nuclear development in Somerset, has repeatedly overrun budgets and timescales.
On Wednesday, Rachel Reeves, the Chancellor, underlined Labour's commitment to the mega project, arguing that she and Ed Miliband, the Energy Secretary, believed pushing ahead was 'the right choice for bills, the right choice for jobs and the right choice for growth'.
As part of the spending review, Ms Reeves confirmed £14bn of funding for Sizewell C through 2029 – taking the Government's total promised investment to more than £17bn.
The rest will come from a group of private investors, potentially including British Gas owner Centrica, as well as French state nuclear company EDF, which will build and part-own the plant.
EDF is expected to put in up to £2bn of extra cash, enough to secure a stake of about 20pc. That will require sign-off at the highest levels, including from the company's board and the Elysée Palace.
One potential investor suggested EDF would probably maintain a stake of at least 10pc to ensure market confidence. The company will also benefit from the deal through billions of pounds worth of equipment orders.
However, the politics of backing the British plant are complicated in France, where critics believe EDF is already over-exposed to Hinkley Point C and want the state company to focus on projects at home.
'I am sure the French government will try to get something in return for agreeing to put a bit more money in,' the investor added.
A final funding deal is expected to be signed off at an Anglo-French summit next month.
Other potential investors in the frame include Amber Infrastructure Partners, Brookfield Asset Management and the Canadian pension fund CDPQ – run by former John Lewis boss Dame Sharon White in the UK.
On Wednesday, the Government refused to comment on Sizewell C's cost.
Whitehall sources insisted that the estimate had not 'doubled', but did not provide further information.
Sources close to the process have told the Telegraph that the project is expected to cost £30bn in 2015 prices.
This is an increase of 50pc compared with the original £20bn estimate. But the figure rises to £41bn when adjusted for inflation.
The £30bn total includes about £10bn in equity that will be raised from investors and another £20bn of debt.
'Learning curve'
It means that, on a like-for-like basis, the project is on course to be cheaper than Hinkley Point C, which uses a near-identical design. Hinkley is expected to cost £31bn to £34bn in 2015 prices, according to EDF.
The lower cost of Sizewell is due to 'learning curve' efficiencies, with supply chains and skilled workers set to be carried over from Hinkley.
But despite this, and the money committed by Ms Reeves, the Government has so far refused to officially confirm what it expects the project to cost in total.
Alison Downes, of the Stop Sizewell C campaign group, said: 'Given negotiations with private investors are incomplete, Sizewell C really should be excluded from Wednesday's announcements.
'Where is the good news in a project that will cost tens of billions, add to consumer bills and is guaranteed to be late and overspent?'
A spokesman for the Department for Energy Security and Net Zero said: 'Hinkley was built after decades of no new nuclear.
'We are filling the gap with a new nuclear programme which will see greater efficiencies and learnings carried across projects.
'Sizewell C will be an almost exact replica of Hinkley Point C – but crucially learning from previous mistakes and replication.
'EDF says that the second unit of Hinkley is getting built at a rate 25pc quicker than the first, and Sizewell C is effectively a third and fourth version of this reactor.'

Lydney residents and businesses to celebrate reopening of bridge
Residents are holding a celebration for the reopening of a bridge, almost eight months on from when it was damaged by flooding and a bridge on Newerne Street, Lydney, closed in November after Storm Bert swept floodwater through the Gloucestershire town. In December, a car hit the bridge, causing further was partly reopened in January but fully reopened on Friday after weeks of repair work, with the community planning a celebratory fun day on Harris, from Gloucestershire County Council, thanked residents for their patience. Grace Williams from Knockley Pet Foods, which overlooks the bridge, said Saturday morning's festivities were being held to thank those who supported the business."Our customers are amazing and they did continue to support us, we know it was really difficult to get to us," she said."A lot of the other businesses weren't so lucky... town itself has been really quiet."We're definitely relieved that it's open, it's going to be a lot easier." Kirsty Scott, who owns refill shop Forest Friendly on Newerne Street, said the bridge opening was "perfect timing" for the summer holidays and tourist season."Business owners are [relieved], definitely, and I think people who own hot cars in this hot weather are too," she said."It's been eventful and I've seen a lot of traffic sitting outside. It seems quieter today because it's flowing in both directions." Joe Harris said "final work" to the bridge wall would be completed off-road, without causing traffic disruption."I do appreciate the impact of the closure on local residents and businesses and thank you again for your patience while we completed the essential repairs," he said."Thanks also to the team who tackled this challenging job which included diving below the bridge to check for structural damage."

Norfolk council leader sorry over 'poor people' Facebook post
A council leader apologised "unreservedly" for posting a picture of a steak dinner on Facebook with the words: "Wonder what all the poor people are doing?"Norfolk County Council's Conservative leader Kay Mason Billig said it was a private joke that had been taken out of context and the comments were "not intended to be about anyone else".A copy of her post, which showed a tomahawk steak, red wine and a salad, was shared with the Eastern Daily council's Liberal Democrat group leader Brian Watkins said it made "a mockery of many in our county struggling to make ends meet" and called for her to resign. Mason Billig, who has led the council since 2023, said: "Of course I apologise unreservedly if I have caused any offence, it was never my intention to do so."She said the image – taken from her personal Facebook page – was being "twisted into something it isn't"."My husband and I have sometimes called ourselves 'the poor people'," she explained."It's a private joke as we live fairly modestly, so when we have a treat, we will sometimes post about it."It's not intended to be about anyone else and is no reflection on people who are less well off than ourselves."I am deeply disappointed that someone has decided to be this horrible when they must certainly know it's actually self deprecation." While the post was made on her personal page, University of Essex professor of government Paul Whiteley said politicians had to be careful using social media."To somebody who didn't know her, it would sound like she was being rude about people who are poor, even if that's not what she meant," he said."That's what it will sound like to the vast majority of people."Watkins, whose Liberal Democrats are the main opposition group on the council, said Mason Billig "should consider her resignation immediately"."A councillor is never off duty. These comments make a mockery of many in our county struggling to make ends meet."Labour group leader Steve Morphew said Mason Billig was "out of touch".
