No more than the true-price of Nuclear is the price to spin-up and spin-down nuclear as the electric grid demands.
There's "baseload power" (coal, nuclear, wind, solar is really good for this), and there's "Peaker power" (natural gas and hydro are really good for this).
Hydro is super-simple. Just block the water if you don't need energy, and unblock it when you need energy. Ditto with Natural Gas, which can spin up / spin down arbitrarily.
Solar, Nuclear, and Wind generate power on their own schedule and can't really be bothered. But you use OTHER forms of energy when the sun stops shining.
Natural gas is expensive to run 100% of the time. But if you can run Natural gas only 20% of the time, then you're still saving money.
