In the UK solar and onshore wind are about 5p/kWh, offshore wind about 7p/kWh, nuclear about 7-10p/kWh, depending on generation of reactor and scale of order, so more expensive per kWh. But you’re right that clearly once you include the cost of grid integration, taking wind or solar above 30-50% will incur significantly higher costs. I think in the UK it’s about 20p/kWh now for solar or wind with four hours of battery firming for example. But the difference is those costs are continually falling each year, whereas nuclear has stayed the same or risen. I would still renew nuclear personally, to provide maybe 15-25% of the grid, but it’s not enormously obvious. I think by the time the nuclear stations are built renewables will probably be cheaper, I just favour it as a hedge. Although in the UK we’ve had some nuclear development companies pull out and ask for more money even after agreeing to build at 10p/kWh, so that may not work out in reality.
