I think you misinterpreted my comment. I'm advocating for an energy mix where the majority of energy is supplied by intermittent renewables with a small amount of low-cost (i.e. not nuclear) dispatchable generation. This avoids the extortionate "last mile" of costs when utilising 100% intermittent renewables.

The Clean Power 2030 report from NESO came to a similar conclusion. See Insights from our clean power sensitivities, pg 53: https://www.neso.energy/document/346651/download
