> we still need all the conventional back up. So all you save is a small amount of relatively cheap fuel, but you still incur all the capital and O&M costs, plus the costs of the "renewables".
As carbon-emitting storage becomes steadliy more proscribed (and it will. Look at what's happening int he Laptev Sea), that backup generation will have to become nuclear - which currently doesn't load follow very well.
Moving to molten salt systems makes load following trivial, but at that point the renewables become surplus to requirements because MSR designs should produce power at ~1/4 the cost of renewables.
