Britain remade – with a lot of nuclear?

the land on which renewable techs sit is not all lost to other uses and offshore wind farms use no land. And the nuclear fuel cycle (from uranium mining through to eventual waste disposal) also involves land use.

In a new report, the Britain Remade lobby group pushes nuclear strongly, as part of its ecomodernist growth-based future. It models different nuclear build costs and renewable price scenarios to assess long-term impacts on household energy bills. But although it accepts that ‘renewables may have seen large price-falls over the last 15 years’ it says that ‘at high penetrations costs linked to managing intermittency are high: Britain has added 40 GW since 2010 and 120 GW is forecast by 2030, yet balancing, curtailment, backup, and overbuild still add cost and leave gaps that require firm power’.

It is also not very happy about the local environmental impact of renewables, given their high land use compared with nuclear plants. Well yes, but the land on which renewable techs sit is not all lost to other uses and offshore wind farms use no land. And the nuclear fuel cycle (from uranium mining through to eventual waste disposal) also involves land use.

The new report does admit that Britain is the most expensive place to build nuclear capacity. It notes that ‘Hinkley Point C (HPC) is estimated to cost £46 billion, or £14,100 per kW: when finished, it will be the most expensive nuclear power station ever built. British-built plants cost far more per kW than peers: our per-kW costs are about six times South Korea’s, and France and Finland deliver the same EPR design for less per kW (27% and 53% respectively). Britain has gone backwards on cost: Sizewell B in 1995 cost £6,200 per kW, less than half Sizewell C’s budgeted cost.’………………….

To improve things in the UK (not an easy task you might think, using the same vendors) it wants better regulation and reduced planning barriers. Well we will see how that goes with EDF’s new Sizewell C EPR. But better planning systems and regs might also help renewables ! Overall Britain Remade seems a bit desperate in its promotion of nuclear: ‘If renewable costs rise, nuclear can play an even larger role: government forecasts assume falling solar costs (-27% by 2040) and modest wind cost drops (-6%), but recent data show solar prices flat and wind costs rising. If renewables costs climb 30% above baseline, the most cost-efficient plan would be eight new plants at French prices (saving £7.6 bn) or fifteen at Korean prices (saving £21 bn) over 25 years, with benefits lasting decades’.

Lots of assumptions about costs there, and also about demand and markets, with there being some big uncertainties. …………………………

……………………………………………………………Not everyone in the UK will relish American dominance, even in a collaborative context, if that is what we face in this sector, and maybe in others, like AI. However, for good or ill, the Labour government, like most governments, is wedded to technology-led growth. So, with China now politically bared and the EU somewhat out of bounds, US help is evidently seen as vital. Like the US, the UK is now pushing nuclear hard: 75% of the Department of Energy Security and Net Zero’s £6.7bn spending in 2024-25 was allocated to nuclear.

It is true that renewable are also being pushed in the UK (not now under Trump in the US), but mainly via private sector investment e.g. £1.5bn for last year’s CfDs. Which way might it go in future given the US influence? The new US-UK ‘technology prosperity’ deal pushes nuclear and also AI hard, but ignores renewables. You will find exactly the opposite approach in Electrotech, the new Ember global energy report, with renewables dominating, a view also shared by the latest World Nuclear Industry Status report, which depicts nuclear as mostly declining and as something of a dead end option – see my next post. https://renewextraweekly.blogspot.com/2025/09/britain-remade-but-mostly-with-nuclear.html
