@Ardubal @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis Farm scale solar, onshore and offshore (non-floating) wind cost approximately £50 per MWh in the last CfD auction. That's half the CFD agreed for Hinkley C.
Mature renewables are already cheaper than nuclear. By a factor of two, compared to first-of-a-kind over-budget new nuclear.
@matthewtoad43 @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis
Again, £50 per MWh is at current penetration levels of volatiles. This doesn't scale linearly.
See that you get to more-of-the-same-kind nuclear reactors. This does.
@Ardubal @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis What do you mean it doesn't scale linearly?
If you need to over-build by 3x, then it costs £150/MWh.
If you need to use £170/MWh storage for 10% of demand (plausible for hydrogen), you still get a very reasonable figure.
There's no obvious non-linearity here. Switching off renewables is trivial, unlike thermal plant.
