He's not much of a polished presenter here, but this is pretty self-explanatory at that price point.

The UK government just signed an agreement guaranteeing a price of 16 cents per kilowatt hour for power generated by a reactor proposed for Hinkley Point, on the coast at Somerset, England. That fresh contract represents an example, Gundersen argued, of the market price of new nuclear power.
Solar power costs six to seven cents, he said, and wind costs four or five cents. Add 2¢ for the cost of a utility-scale Tesla battery, and renewables with reliable storage are still at half the price of new nuclear power.
They’re also approaching the price of existing nuclear power.
“Here in Illinois you know it’s true because Exelon is threatening to close five nuclear plants because they can’t compete with wind anymore.”
