The storage costs only kick in when they supply the grid. So for 4 hours of storage you have 20 hours of the pure renewable cost supplying the grid and charging the storage and 4 hours with storage filling in the gaps. That is also the marginal cost of nuclear power. What Hinkley Point C is expected to end up at after running for 35 years. So sometime 2065. Before that Hinkley Point C is costing the consumers ~$180/MWh which are energy crisis costs. > That's like saying that any long term infrastructure is only possible with bad math... Not at all. The difference with nuclear power is that we have viable alternatives which do not need bad math financing the subsidies to get built.
