This is wildly overstating the issue. Hackers are not going to break into hundreds of separate sites, compromise inverters, compromise relay protection, compromise SCADA systems, and execute a perfectly timed attack. Even if they did, these are distributed resources, they don't all go through a single substation and I doubt any one site could cause any major harm to any one substation.
Instead, they're going to get a few guys with guns and shoot some step of transformers and drive away.
The problem with infosec people is they tend to wildly overestimate cyber attack potential and wildly underestimate the equivalent of the 5 dollar wrench attack.
