The NextEra graphic says "near-firm", not "firm". Some dispatchable generation is absolutely required.
The estimate is for late 2020s costs, which is not too far away. I'm guessing they ignored the end of the solar subsidy, and all the necessary grid changes to reach 100% renewables.
The O'ahu batteries replace the last coal plant, but not the last fossil fuel plant. Also, it's meant for black-start.
Nobody knows exactly what the last mile will look like yet. The graphic doesn't claim to know either. As a reader, you should not extrapolate those near-term forecasts and anecdotes all the way to the end.
- toomuchtodo 4y agoAgreed no one knows what the last mile looks like, but all data demonstrates fossil fuels have very little role in that last mile. Your splitting hairs while the data is a bazooka of good news (with regards to cost decline and tech/manufacturing learning curves).
- linkdink 4y agoI didn't think I was splitting hairs. The data does not suggest what you say because the foundational assumptions stop being true the closer we get to the finish line. That's why you can't extrapolate the current trend all the way. It will take a different path.
