Falta muchísima inversión. Una línea circular, en paralelo a la M40, cuadriplicando las vías de la Civis de San Fernando-Chamartin para construir una estación junto a IFEMA y otra junto al Wanda.

Pero vamos a ver, por favor. Un poco de seriedad. "Demostró su utilidad durante el apagón", ¿pero qué tontería es ésa? Ninguna isla canaria (ni balear, ni Ceuta, ni Melilla) sufrieron el apagón porque son sistemas independientes. Pero por favor, que son la televisión pública.

Conclusion:
1️⃣ Does renewable energy lack inertia? Yes, because we impose it.
2️⃣ Did this play a role in the blackout? Probably not, but it certainly did not help counteract the blackout.
3️⃣ Was there a lack of inertia? There didn't seem to be. /15

Roughly speaking, this would be enough to bridge the loss of the 18GW solar 2.6s - ample time for other safety mechanisms to intervene (response times of those systems are in the order of tens of milliseconds). So there is more to the blackout than just the inertia thing. 14/

Returning to Spain, moreover, there is no indication that there was a shortage of inertia. At the time of the blackout, there was 10GW of classical generation out of a total consumption of ~30GW. At a classical τ = 5s, that is 50GWs of inertia. 13/

Wind turbines, on the other hand, do have a lot of mechanical inertia, just like conventional power plants. But this too is not allowed to be used to support the grid. ** The lack of inertia in renewable energy is therefore the result of a conscious policy choice. 9/

Does renewable energy also provide such inertia? No. But that's not because it can't. It is because it is not allowed.
Renewable energy is decentralised by definition: many small installations spread across the grid. Sometimes a grid operator wants to take a piece of that grid offline 3/
