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/

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
* depending on the number of pole pairs
** there are (recently tightened) requirements for grid support by inverters, but these are more focused on local grid support and, all in all, are of little consequence in the event of a total blackout /

Thanks, Mike
Thanks a million!
I'm really thankful for this.
Synchronous Condensers, Pumped Hydro working as an SynCon, regular hydro.
So rotating mass doesn't need to be driven by fossil fuels.
Grid forming batteries and Enhanced STATCOMs are other options.
Just deploying SynCons is a conservative proven solution .
