Chris Nelder š¤Hat tip to John Kemp for admitting that he was wrong to blame Spain's blackout on excessive reliance on inverter-based renewables and insufficient inertia, and š for his very decent explainer on what actually happened. https://jkempenergy.com/2025/06/19/spains-blackout-blamed-on-poor-voltage-control/
Jeff McNeill@chrisnelder Great read, thanks.

I've seen claims that batteries can contribute reactive power.
This report mentions a lot of different possibilities for stabilizing the system, but not batteries. Don't they work, or are they just not very useful in this context?
@notsoloud You have read the report John refers to in footnote 1 (from a Spainās Council of Ministers)?

No, merely the blog post by John Kemp.

TomThe report recommendations are more about structural and policy changes rather than specific technologies but it does explicitly recomend boosting storage.
Andrew HenryWe await Javier Blasā explanation.
zl2todThis explanation for Spain's electricity system collapse is particularly interesting given the New Zealand government's recent announcement that mains voltage limits are to be relaxed from Ā±6% to Ā±10%.
