I believe the difference is that during a Dunkelflaute, peaker plants might have to generate a large amount of or the majority of electricity, whereas today, peaker plants are build to only generate relatively small amount of power at the margin.
So, we'd have to build a large number of peaker plants, which are really expensive in that they have to amortize their costs over a small amount of uptime.
- froh 4y agoshort term weather forecasts are amazingly accurate. this allows us to deliberately "extend" the "range" of buffer storage. and even today in some situations some energy intense heavy industries have to pause production for a few hours if there is a lack of energy supply. It's a political problem, not a technical one, and we do not, absolutely not have to build up new parallel peaker capacity. we can simply keep select plants alive.
- golem14 4y agoFiguring out how much extra capacity is needed still needs to be done. Simply stating that no new peaker plants are needed "because storage capacity will be there" is a bit too simplistic. I'd be glad if that's the case, but I'm not convinced it's actually true.
- froh 4y agoright we have 7 years to figure this out for 80% renewables and 17 years to figure it out for close to 100% it took 1 year to build and start operation of giga Shanghai, and not much longer for giga Berlin. it's a political challenge, not a technical one.
