But acts as drag on the speed.
Right.
When you see your generators slowing down, well, when you see the grid frequency dropping, you know you need to put more electricity onto the grid to reduce the load per generator, right?
Essentially.
So that was the feedback loop you could literally use to control the grid in the old days.
Yeah, I think it's complicated, right?
The simple thing is, if you keep an eye on frequency in a traditional grid, you know whether you've got excess load or indeed insufficient load, right?
Right.
It's an automatic feedback loop.
In a renewable grid, the electricity is not generated by things that are spinning.
So what happens is you can't any longer rely on the old analog system that the frequency is the signal for what you need to do.
Instead, you need digitalization and access to, you know, you need to be reading what is the load digitally and you need to be able to respond digitally.
You know, for example, by using batteries to be able to either soak up power or dump some onto the grid quickly to maintain that kind of supply and demand balance of which the frequency is an indicator.
So first of all, we should say that, you know, look, some of the most committed, dedicated and smart people I know include grid engineers.
The sense of mission, professionalism and dedication, plus absolute technical expertise is off the charts.
Let's note that.
I think there are a couple of features of any transition.
The first one, by the way, is the assumption that we need a grid of, say, 50 hertz in the European figure, right?
Because if you're like in the traditional grid, where the frequency was a byproduct of how we were generating it, as well as we controlled it, everyone's alarm clocks used to run off the grid frequency.
Obviously, these days, they don't.
