Sizewell C power to cost almost double today’s prices

Nuclear plant is an ‘appalling waste of electricity consumers’ and taxpayers’ money’, experts claim

Jonathan Leake,

 Electricity generated by the Sizewell C nuclear power station will
cost roughly double the normal price of power, according to a new
Government report.

Estimates suggest that the power Sizewell C produces
will cost £120 per megawatt hour (MWh) in today’s prices, compared with the
current wholesale price of about £60 to £70. The extra costs will be added
to energy bills.

The disclosure was made in a review of the business case
for Sizewell C published by the Department for Energy Security and Net
Zero. It is understood to be the first time Sizewell C’s power output has
been costed. It refers to the so-called “strike price”, which is likely
to be awarded to the nuclear power station under the contracts for
difference system. This is where generators get a guaranteed minimum price
for electricity, whatever the market value.

The cost is then covered by a
levy on consumer bills, meaning it effectively acts as an energy subsidy.
Nuclear supporters, including Ed Miliband, the Energy Secretary, have
argued that nuclear power is worth the extra money because it acts as a
secure energy source for decades – potentially a century in the case of
Sizewell C.

However, critics have raised concerns that prices for nuclear
will continue to rise, arguing that early estimates for constructing power
stations are always significant underestimates. They have pointed to
Sizewell C’s predecessor, Hinkley Point C, where original costs of £18bn
have soared to £50bn – a figure announced last week – with start-up delayed
from 2026 to 2031.

The Government report for Sizewell C said estimates
assumed no escalation in costs, which would be a first for UK nuclear
construction projects. The report also warned that consumers were likely to
be charged more than the £120 per MWh rate because the strike price was
calculated net of all the tax, business rates and other payments to the
Government.

Prof Stephen Thomas, the editor-in-chief of Energy Policy, an
academic journal, said: “Sizewell is an appalling waste of electricity
consumers’ and taxpayers’ money. If you want to justify a premium price for
nuclear, you have to estimate the costs of achieving the same factors –
energy security and reliability.

“Of course, nuclear power plants aren’t
always reliable and the most insecure power source is the one that isn’t
built yet. Without the assumptions behind these cost guesses [of £120 per
MWh], they are worthless and far from transparent.” Alison Downes, of
Stop Sizewell C, a local campaign group, said: “Hinkley’s cost has soared
to £50bn with completion dates slipping and five years still to go.
Sizewell C’s costs will rise higher still when it inevitably overruns its
£40bn construction budget.”

EDF pledges new £15bn UK investment as falling energy prices hit profits

The energy firm reported a 12 per cent decrease in nuclear output

Anna Wise, Independent UK, Monday 23 February 2026

French energy giant EDF saw its UK profits decline last year, attributed to a combination of falling energy prices and a significant outage at one of its nuclear power stations.

Despite this setback, the company has announced plans for a substantial £15 billion investment in the country over the next three years.

The energy firm reported a 12 per cent decrease in nuclear output from its five operational power stations during the period.

While its Sizewell B facility in Suffolk and Torness in Scotland performed strongly, the overall output was significantly impacted by an extended outage at the Hartlepool power station.

The Teesside-based station, which began generating power 43 years ago and supplies electricity to approximately two million homes, experienced a prolonged shutdown.

Despite these operational challenges, Hartlepool recently secured a one-year extension to its operational lifespan, now expected to generate electricity until March 2028.

This extended downtime, primarily due to issues affecting one of its two reactor systems, was identified as the main driver for EDF‘s overall decline in nuclear generation last year.

Furthermore, a decline in earnings was also down to the prices it charges for nuclear power being lower than in 2024.

It is understood that average prices were down by approximately 20 per cent.

Energy prices in the UK have been gradually coming down after spiking in the aftermath of Russia’s invasion of Ukraine in 2022.

EDF said that in its UK business, earnings before 

interest, tax, depreciation and amortisation (EBITDA) were £1.9 billion for 2025, down about a third from £2.9 billion in 2024……………………………………………………….. https://www.independent.co.uk/news/business/edf-hinkley-point-energy-prices-profits-b2925974.html

Hinkley Point C faces further delays as costs continue to mount

Hinkley Point C, the UK’s first nuclear plant in a generation, is now not expected to start generating electricity until 2030 at the earliest in yet another delay to the project.

French energy giant EDF, which has been overseeing construction on the nuclear plant, blamed the delay on lower-than-expected productivity on its major electromechanical installation programme. 

The programme includes installation works such as piping, cabling and system integration for both reactor units – although only Unit 1, the first reactor, is expected to begin generating in 2030. 

Unit 2 is generally expected to come online about one year after Unit 1, which suggests it will be the early 2030s based on how the project timeline is currently understood. Workers only lifted the 245-tonne steel dome onto Unit 2 in July 2025, roughly 18 months after Unit 1.

Last month, Hinkley Point C received the second and final  nuclear reactor that will be welded into place in the coming years. The power station received its first nuclear reactor in 2023, which has subsequently been installed in Unit 1……………………………………………………………………………………..https://eandt.theiet.org/2026/02/23/hinkley-point-c-faces-further-delays-costs-continue-mount

Cost of Hinkley Point C nuclear plant jumps again to nearly £50bn

The rising cost — and a further delay to the completion date — will be seen as a blow to the UK’s energy security and an indictment of its infrastructure record. The cost of the Hinkley Point C nuclear power station has ballooned to nearly £50 billion and the date when it is expected to be in service has been put back again to 2030.

It does not
augur well either for a second major new nuclear power station, Sizewell C
in Suffolk, which is in the early stages of construction. The news was
revealed in statements in Paris on Friday by EDF, the state-owned French
energy company contracted to build Hinkley Point and Sizewell C.

The company estimated that the cost of Hinkley C was now £35 billion at 2015
prices. Adjusted for inflation, that translates to up to £49 billion. The
original projected cost was £15 billion. The plant is already years late,
as it was originally expected to go into commission in the mid-2020s.

Some argue that the date could yet be pushed back into the 2030s, leaving a
significant gap in UK energy policy after coal-fired power stations were
closed, leaving the country increasingly dependent on giant wind farms in
the North Sea. Consumer energy bills are at historically high levels.

EDF has further pushed back the start-up of the UK’s flagship HinkleyPoint C nuclear plant.

EDF has further pushed back the start-up of the UK’s flagship Hinkley
Point C nuclear plant, taking a €1.8bn charge and pushing up the final
bill for a project that has suffered several delays and cost overruns.

The French state energy company said the first of the two reactors at the 3.2
gigawatt project in Somerset would now begin operating in 2030, blaming
delays in “electromechanical work”. That compares with a previous
“best case” target of 2029, itself a two-year delay from an earlier
timetable.

When the project was given the go-ahead in 2016, it was due to
come online in 2025. EDF said the plant was now expected to cost £35bn in
2015 prices — or almost £49bn at today’s prices — compared with a
previous range of £31bn-£34bn. The project was costed in 2016 at £18bn
in then-current prices. EDF warned that a further delay to 2031 would add
another £1bn.

British taxpayers bankroll French nuclear giant while Hinkley Point C quietly receives 500-tonne reactor heart.

The contrast couldn’t be starker: French taxpayers owning British energy infrastructure, while British taxpayers guarantee the profits.

For a typical family using 3,000 kWh annually, the Hinkley surcharge could add £15-25 yearly to bills once the plant is operational. That might sound modest, but it’s on top of already record-high energy costs and other energy levies.

Sarah Mitchell stared at her energy bill in disbelief. £340 for the month. Again. The single mother from Bristol had already switched off the heating in two bedrooms and started cooking with just one burner. Yet somewhere across the Channel, a massive steel cylinder was being loaded onto a ship, destined for her county of Somerset. That 500-tonne nuclear reactor vessel would eventually power her home—and she was helping to pay for it, twice over.

It’s a story playing out across Britain right now. While families ration their heating and businesses close early to save on electricity, a French-built nuclear giant is making its way to British shores. The destination is Hinkley Point C, the controversial power station that’s become a symbol of everything complicated about Britain’s energy choices.

The scene in Cherbourg was deliberately low-key. No cameras, no politicians cutting ribbons. Just dockworkers watching as France’s most sophisticated nuclear technology rolled toward a waiting vessel, bound for a country that’s paying through the nose for foreign expertise.

Hinkley Point C represents the biggest bet Britain has made on its energy future in decades. When the deal was struck in 2016, it looked like smart planning. Today, with energy prices through the roof and household budgets stretched thin, it feels more like an expensive gamble with other people’s money.

The reactor pressure vessel now crossing the English Channel is the beating heart of what will become Britain’s newest nuclear power station. Built by Framatome, France’s state-owned nuclear champion, this steel colossus will sit at the center of two European Pressurised Reactors (EPR) designed to generate enough electricity for six million homes.

“This vessel represents the pinnacle of nuclear engineering,” explains Dr. James Crawford, a nuclear physicist at Imperial College London. “But the question isn’t whether it’s impressive technology—it’s whether British taxpayers should be funding French state enterprises while struggling with their own energy costs.”

The numbers behind Hinkley Point C make for uncomfortable reading. The project has ballooned from an initial estimate of £18 billion to potentially over £35 billion. Meanwhile, British households are locked into paying a guaranteed “strike price” of £92.50 per megawatt-hour for the electricity it produces, inflation-adjusted over 35 years.Follow the Money: Who Pays and Who Profits

The financial structure of Hinkley Point C reads like a masterclass in how to transfer risk from private companies to ordinary citizens. Here’s how the money flows:

The strike price mechanism means British energy users will pay a premium for Hinkley’s electricity regardless of market conditions. If wholesale prices fall, we top up the difference. If they rise above £92.50 per MWh, EDF keeps the extra profit up to a point—but taxpayers still carry the underlying risk.

Key financial commitments include:

• £92.50 per MWh guaranteed electricity price (2012 prices, now worth over £110 with inflation)
• 35-year contract duration with built-in price increases
• Government loan guarantees reducing EDF’s borrowing costs
• Planning and regulatory costs covered by British authorities
• Decommissioning fund contributions from British sources

“It’s the most expensive electricity deal in Europe,” notes energy economist Professor Michael Roberts from Oxford University. “We’re essentially giving EDF a 35-year annuity underwritten by British households, while they retain ownership of a strategic asset.”

Real Homes, Real Bills, Real Consequences

While the nuclear reactor makes its journey from France, the human cost of Britain’s energy choices plays out in living rooms across the country. The Hinkley Point C contract means every household will contribute to EDF’s guaranteed profits through their electricity bills for the next three and a half decades.

For a typical family using 3,000 kWh annually, the Hinkley surcharge could add £15-25 yearly to bills once the plant is operational. That might sound modest, but it’s on top of already record-high energy costs and other renewable energy levies.

The timing feels particularly brutal. As the French-built reactor vessel crosses the Channel, British families are making impossible choices between heating and eating. Food banks report unprecedented demand, partly driven by people choosing groceries over gas bills.

“My constituents are furious,” says MP Caroline Davies, whose constituency includes several towns near Hinkley Point C. “They see foreign companies profiting from guaranteed contracts while they’re choosing between turning on the heating or buying school uniforms for their kids.”

The broader economic impact extends beyond household bills:

• Small businesses closing early to avoid peak-rate electricity charges
• Manufacturers relocating to countries with cheaper, more predictable energy costs
• Public services cutting back on heating and lighting in schools and hospitals
• Pensioners rationing heating despite rising winter fuel allowances

Meanwhile, EDF’s shareholders—ultimately the French state—benefit from one of the most generous infrastructure deals in recent British history. The contrast couldn’t be starker: French taxpayers owning British energy infrastructure, while British taxpayers guarantee the profits.

The situation raises fundamental questions about energy sovereignty and democratic accountability. When foreign state-owned companies control critical infrastructure that British citizens are compelled to fund, traditional notions of national ownership become meaningless,

Energy analysts warn this model could extend to other major projects. If Hinkley Point C proves profitable for foreign investors at British expense, similar deals for future nuclear plants, offshore wind farms, and other infrastructure become more likely.

As that 500-tonne reactor vessel approaches British waters, it carries more than just sophisticated nuclear technology. It represents a profound shift in how Britain powers itself—and who controls the switch.
