Consistent electricity is a completely unreasonable design assumption for that part of the world. Even backups aren’t enough. Zoos already have enclosures that don’t require electricity to keep animals contained.
Yeah, I totally misspoke in my comment. By “backup”, I didn’t mean e.g. a backup generator. I meant that in addition to the electric fences, there should be physical barriers like a tall, steep wall that can, at minimum, reliably hold the dinosaurs regardless of the fence. We see these in the movie, but I think the idea is that they aren’t used consistently. It’s been a while since I’ve watched Jurassic Park.
The electric fences are seemingly a 100% foolproof way of keeping the dinosaurs in while the electricity is running, and I’ll even take Hammond at his word that he can have perfect uptime without planned human interference like Nedry’s. So in that sense, the fences are more like a backup to the physical barriers, not vice-versa.
So you want (from inside–out):
Static physical barriers like water, tall walls, etc.
An electric fence. Even if unelectrified, it still offers some small, temporary protection from the smaller dinosaurs, and it’s effective at keeping out dinosaurs who somehow get past (1).
A barrier more effective than the concrete base of the fence seen in the movie so that a visitor can’t run up and get electrocuted.
Periodic shelters throughout the park for some freak accident.
