I’m guessing the grid is not designed to handle restarting such large areas at once or they don’t eave enough competent engineers to develop a plan to re-energize smaller areas at a time.
I know someone who worked for a large refrigerated/frozen food warehouse. In the event of a power outage, they had specific procedures to restart refrigeration equipment as you could blow transformers if everything tried to start all at once.
maduro shot one of the engineers over the last couple days....he hasn’t a clue who to trust at this juncture.
From the photos I’ve seen of the grid there was lots of undergrowth choking it so you can Imagine the grid is in rough shape. It’s also reported even back up generators for hospitals etc weren’t working and not even helpful.

Restarting the national power grid from scratch is nontrivial, especially when its quite likely the technical staff necessary to do so has glad the country and/or are scrambling for food to keep their families alive.
You are right about having to re-energize small and grow only as things remain stable.
But to do that a lot of engaged switches would have to be opened, and at this point ain’t nobody got time fo’dat.
