Hinkley Point Nuclear is really a colossal miscalculation of risk management.

Costs Continue To Rise For Hinkley Point Nuclear Megaproject

Or was this another legacy project of the Tories’ whose main desire was to protect Britain from the labor militancy of  British coal miners whose last bitter, year long strike ended in 1985? From what we can tell, the UK government simply wanted a new nuclear power generating station period—more likely for national prestige—and not a discussion of alternatives, or the risks incurred by builders, or the financial consequences imposed on consumers by this decision.

• The cost estimation for Great Britain’s Hinkley point C nuclear power plant has effectively doubled from 2016 to 2023.
• Hinkley Point is really a colossal miscalculation of risk management.
• The Hinkley point C project shows that the single asset concentration risk is too high for the utility company in question.

For close to a decade, Great Britain’s Hinkley Point C nuclear power project has served as the go-to punching bag for anti-nuclear activists. Sure enough, the gift that keeps giving has furnished still another reason to be chary of big nuclear projects.

Background for those not in the know. The current Hinkley Point nuclear project was the brainchild of British energy planners in the early 2000s. Their goal was to build another big nuclear plant at an existing site. Several actually. French state-controlled EDF took on the task with big British energy supplier Centrica as a minority owner. But Centrica soon backed out due to the escalating costs. EDF brought in a Chinese state company as a replacement partner. The UK government signed an agreement guaranteeing that the unit would collect a generous price for power generated (an insanely high price according to one critic at the time). In 2016, the project commenced with an estimated cost of £16-17 billion.

Oilprice readers will not be surprised that these costs kept rising. In February 2023, EDF estimated that the final cost would be close to £33 billion ($40 billion), a 100% increase versus the initial estimated cost to completion. The Chinese partner may not agree to further investments beyond those initially agreed to so EDF could be exposed to even higher costs. With the completion date set for 2027, should we expect more increases? 

The news stories cite inflation as a primary reason for the cost increases. But the UK’s construction price index rose 40% between 2016 and 2023, while the estimated cost of the nuclear plant almost doubled. One distinguished economist noted that the plant would have cost far less if the government had financed it, but that is another matter. 

Hinkley Point is really a colossal miscalculation of risk management. Start with this statistic. The Hinkley Point project investment to date equals roughly one-fifth of the enterprise value of EDF. There are 56 other nuclear plants in EDF’s portfolio. One of the lessons learned by most US utilities after the Three Mile Island accident was that big nuclear plants and relatively small electric utilities are not a good match. In technical terms, the single asset concentration risk is too high. One might argue that EDF is big enough to take the chance, but that is clearly not so.  

Then there is the matter of whether the British government worked out its aims and the risks of the various solutions. Why did the UK need this nuclear project? To protect against the insecurity of foreign energy supplies? Wind turbines, solar and domestic natural gas would do that.  Or was it the main goal of policy makers to reduce greenhouse gas emissions? In this at least they may prove successful but there are much cheaper alternatives. Consider as an alternative weatherproofing all those damp and cold council houses which were designed to be drafty due to earlier pandemics and worries about gas safety. That would have saved a lot of energy and reduced the need for the project.

Or was this another legacy project of the Tories’ whose main desire was to protect Britain from the labor militancy of  British coal miners whose last bitter, year long strike ended in 1985? From what we can tell, the UK government simply wanted a new nuclear power generating station period—more likely for national prestige—and not a discussion of alternatives, or the risks incurred by builders, or the financial consequences imposed on consumers by this decision.

This brings us to our final point. Hinkley Point C is a classic giant project, a category of construction brilliantly analyzed by British analysts in the 1980s. It is a huge effort that will take years to complete, requires a guess at market demand years from the date of inception, and once complete and in service will have a big impact on the market all at once when completed. In addition, this project involves many different owners and contractors, domestic and international, plus multiple national governments and requires the owner/builder to finance a project whose failure might have disastrous financial consequences for it. In other words, the project entails taking not only many risks but big ones. So why didn’t they consider alternatives first before plunging in?………………  https://oilprice.com/Alternative-Energy/Nuclear-Power/Costs-Continue-To-Rise-For-Hinkley-Point-Nuclear-Megaproject.html
