When you consider that Germany closed 4GW of nuclear power generation, then few MW (Don't you think MWh?) projects are magnitudes off what is necessary.
It's about day storage and regulationary skills not about replacing nuclear.
Megawatt seems like the wrong unit as it doesn’t measure capacity. Please provide a link.
Rwe is building 235 Megawatthours capacity with 220 Megawatt output.
So when there is demand, the thing is depleted after ~1 hour.
