They pretty much refused to invest in and install any forward looking technologies (microgrid tech, tech to quickly cut off power to damaged lines, battery storage, more distributed generation, more switches to help isolate parts of the grid, etc.). They just wanted to continue building new natural gas plants and to fight against distributed solar.

They could have spent the last 20 years working to make the grid for nimble, flexible, and safe. They also could have actually done the tree trimming they were supposed to do. Instead they slow walked all innovation and are now scrambling to make up for it.
