Assuming theyre above with a cost of electricity of ~$0.20/kWh

Can we assume that, after factoring in the actual portion that the accounting says goes to the power plant itself? The economics of utility scale electricity includes both generation and transmission, so you can't just take that retail price and assume it all goes to the power plant that produced the electricity.

Wholesale prices tend to stay below 10 cents in most parts of the country, although it sometimes spikes when grids are under strain. I think that's probably a more fair assumption of how much the power plants themselves are paid for their production.
