As a part of Operation: The Morning After, you will come across a Dark Matter Fracking Station and have to proceed through taking it down by hacking its three terminals and enduring an onslaught from minions. They will be a part of the open world, so if you don't want to wait until after Chapter 2 is complete, look for a laser that's actually drilling down into the streets (as opposed to ones that have already penetrated the road and are popping out with three weak spots on its sides, those aren't the stations you're looking for).
