The power grid is still under attack...
(OP)
We had a rather long discussion in this topic last year, but that thread is now closed so I'm starting a new one. For reference, here's the link to that old thread:

So as to start this new thread, there's this item:
Extremists keep trying to trigger mass blackouts — and that’s not even the scariest part
Extremist groups are among those targeting the electricity network, exposing the reporting gaps between the state and federal agencies that oversee its security.

Is "extremists" the new name for the Biden administration? They seem to be the ones most likely to cause large scale blackouts.
Dik, you're obsessed.

Those nuts are known to shoot at roadsigns, old bottles, watermelons and the moon. Why not the odd electric system,
The article doesn't make a lot of sense. Seems like the power companies know they are being attacked. FBI knows. DOE knows. At least about the incidents that meet reporting requirements. Public utility commissions for the most part are political appointees that seldom know or care about anything other then keeping rates as high and as confusing as possible. The power companies apparently don't even care, as long as Wall Street isn't affected and the insurance companies keep on paying for the damages. They continue to build in less security then plastic piggy banks. Seems to be just a story about another clueless PUC official.

The public utility commissions do not care about cyber security, but the grid operators and NERC do. The security in most cases is pretty tight. The physical security, in some cases is tight, but what can you do about thousands of miles of transmission lines, and thousands of small substations.
Yes it is possible to take out an area, but the whole grid, not very easy.
About insurance, many parts of utility operations are self insured. The number of incidents, will affect the rates people pay for electricity. Also what affects the price of electricity, is taxes. So as a voter, you do have an effect on electric rates.

This problem will become more visible as the home smart meters and EV rechargers are modified to incorporate "demand management" . I suppose a rational way to review the need for T+D upgrades will require the use of monte carlo modeling of the system using real data fom prior years but assuming greater use of renewables and demand mangement.

No the grid was not designed for inverter based resources that don't act like rotating machines. All those inverters with the low inertia, tends to move us closer to voltage and frequency collapse.
Worse is the owners of these don't care, and refuse to upgrade there software to correct deficits in there product.

Sure, clouds and snow happen, but even in Texas with direct pipelines from natural gas fields the generator turbines stopped running due to poor regulation allowing ineffective designs.
I wonder if radio transmission for inverter synchronization would help. The free-space speed of light is a little higher than by wire so advanced warning and knowledge of the propagation delay difference might be able to keep it all going.
