They like it.

Far Right groups do this because they believe they can eventually cause enough chaos that the country will descend into infighting, the government will collapse, and they'll be free to dispose of people they hate and maybe even take over government.

Just Google Accelerationism.

I don't believe it. If they're impulsive enough, lacking enough vision, and low-effort to want to rob a cash register, there's 0 reason to take time to figure out how to disable multiple power substations to do it. If they were trying to be smart, surely they know that destroying power substations would really up their legal risk if caught.

My bet is an analysis of their phones/computers will be very revealing, and that they're selling this "robbery" story to try and avoid more serious charges.

Then again, maybe they're stupid in just the right ways.

Look, I'm willing to entertain the idea that New England exists, but are you seriously trying to tell me there's more beyond that? Like Ohio?
