Why exactly does that volatility make operating our electricity grid so much more complex?

So the traditional grids were designed around the large synchronous power plants with rotating mass at 50 hertz, such as, you know, thermal, nuclear, hydro, and so on.

So these machines provide physical inertia, meaning that their rotating mass naturally helps slow down sudden frequency changes.

And every hertz counts here.

And this makes us, the grid, for us, the grid much more stable, more predictable, and of course, gives operators much more time to react when something goes wrong.

Renewable generation on the other side, connected through the power electronics, does not automatically provide the same natural inertia.

And if many variable for renewable resources are added without enough grid forming capability, which are fast control, proper balance, including battery storage, voltage support, and so on, then the grid can become more sensitive to disturbances.

What needs to happen over the next decade for Europe to build an all-electric society that is economically strong, resilient, and climate neutral, all three at once?
