I believe it’s possible to avoid if the proper protocols are in place. Namely, the grid has to be turned off completely before the flare hits and then things will mostly be fine. Just wonder how well we can predict these events.

My understanding is that we actually don't have much of a warning (under an hour), since a CME has to reach the satellite at the Lagrange point between Earth and the Sun for us to know it's about to hit Earth. According to the article below, this includes power companies, but I remain skeptical that there's enough organisation in place to shut down the North American, European or Asian grids in 15 minutes.
