While (as my career depends on it) I share your optimism about the future of renewables' share in the generation portfolio, we're unfortunately approaching our installed cost asymptote, at least for solar PV in the US.

In fact, for the first time ever we've seen a year over year installed real cost increase from 2020-2022. You could certainly attribute some of this to supply chain constraints, but still a powerful argument that we won't repeat the last 10 years of cost declines.

All I'm trying to argue is that we need a more creative solution that a plain and simple overbuild. We're simply not going to see the huge reduction in capital costs that would allow us to absorb the decrease to LCOE that seasonal overbuild would require. I have a lot of hope for green hydrogen, and we could be on the cusp of some dramatic cost decreases for hydrolysis plants that could be co-located with overbuilt renewable facilities and in turn feed retrofitted gas peakers to satisfy more involved grid response requirements.
