The extra capacity is taken into account with "levelized cost". Levelized cost of wind and solar are just a fraction of the levelized cost of energy from new nuclear power plants.

We can estimate the cost of storage to deal with intermittency and seasonality, and renewables will likely come in cheaper than nuclear by the time any nuclear plant whose construction was started today would come on line.

As modeling gets better, renewables look better, as there are more and more ways found to work around the seasonality and intermittency problems.

> With every iteration in the research and with every technological breakthrough in these areas, 100% RE systems become increasingly viable. Even former critics must admit that adding e-fuels through PtX makes 100% RE possible at costs similar to fossil fuels.
