I guess another way would be fixed prices for all nuclear and renewables since they have fixed costs anyway. The thing is, the system already works that way to an extent, as there are a lot of guaranteed prices in renewables and some in nuclear. As far as I can tell, these subsidies are why the market price sometimes goes negative when solar or wind produce a lot: the subsidized sellers don't care, they still receive their guaranteed income based on the quantity of energy they inject into the grid. It seems to me that without these subsidies the market prices would always be high, thus better reflecting the true cost of electricity.

    It's not really a subsidy to have long term contracts. It's just a manner to have predictability, and make it easier to plan things in the future. Some of it is a risk shift on quantity or prices, on who bears the risk if production or demand don't match up, and whose responsibility it is to make those two number match, by cutting power to customers or paying people to disconnect their powerplants from the grid.

    But the long term contracts are often there for price and volume stability. Spot prices will still fluctuate, though, especially if it's unpredictable how much energy different renewable sources will generate at specific times in the future, or how much different customers will want to consume at specific times in the future.

    Either way, it costs a lot of resources to match up supply and demand, and you'll either use prices to help push the numbers together or you consume a lot of resources trying to mandate those numbers come together. Trying to fight price swings will cost resources in some other way.
