Supply costs have surprisingly not that much to do with Californias silly electric rates. They load into the retail rates all kinds of disaster recovery costs, environmental blah blah costs, distribution upgrades, social programs, the list goes on. Plus straight old fashioned corruption in a state sponsored monopoly.

You can get some idea of the BS that gets loaded in by comparing some rates from municipal grids like SMUD vs pg&e. Same supply, fraction of the end user rate.

Anyway, that is to say theres very little useful to draw on here in comparing nuke to renewable cost.

12 Billion in loan guarantees doesn't get paid in bills and isn't an accounting trick that costs nothing: https://www.cbo.gov/publication/60682

That's part of why the shift to renewables. I have a 12kw system on my roof and I pay $220 in December and get $150 back in July.

The economics are getting interesting cause now you can get a 2kw hr battery for like $350 and plugin 400 watts of panel into it and run at least a laptop and basics peripherals forever so the draw on the grid is gonna diffuse over time.
