In my opinion, the "but" is still the "hellbrise" considerations brought up in the Decouple podcast. Renewable energy is fantastic but, at grid scale, has to be coupled with sufficient storage: https://www.decouple.media/p/hellbrise

You can get pretty far with negligible storage. There is a cost tradeoff between storage, peaker plants (those could burn hydrogen, not just natgas) and grid size. 70% renewable with no storage is rather easy.

Not sure if you read the podcast but the whole point is that over-reliance on renewables without a sufficient means to handle oversupply can cause grid instability specific to the Spain/Portugal grid outage.

The reports on the Iberian outage point out that, if solar/wind had been allowed to help, the outage could have been prevented.

The outage was never about renewables, it was caused by bad dispatch of reactive power.
