You are doing the same thing I think, projecting past nuclear costs into the future, and assuming past cost reductions for solar and wind.

In any case, you are not correct about the timelines for renewable and storage. The average time to get an approved grid interconnect is 4 years. And all these power projects can take 5-8 years to deliver.
