So the first thing is energy islands.
The second thing is lack of batteries.
And I think this is really big.
Essentially, you can run a very high proportion renewable grid incredibly reliably.
But you don't do it like you did the old ones.
And we should talk here about market structures as well.
But one key feature of Spain's grid is, I can't remember how, it's got like a fraction of a gigawatt of batteries and actually very little planned in the pipeline.
If I compare that to, for example, the UK at the moment, the UK has got five, six gigawatts of batteries and it's got plans to get to 10 or 20 times that.
And the last bit, I think, is a lack of digitization.
And I think it's shocking around the world how undigital grids are.
We put smart meters in people's homes, but most major substations, components of the grid, are not metered in real time.
There's not much telemetry.
And then we rely upon manual control rooms.
rather than automated systems to balance a grid.
So around the world, the frequency of the grid, it was served for many purposes.
It was an artifact, a product of the fact, you know, we had these big spinning generators.
Now, part of the physics is when there's a very high load on a grid, the rotational speed of those generators slows down.
And that's a signal that you need to put more generators on the system, right?
So essentially... You're sort of bleeding energy, the inertial energy off to kind of keep the grid running.
Basically, it's the physics is when you've got a high load on a generator, then that high load, it essentially acts as magnetism and stuff, right?
