This works best if you are located in one of the suing states, so it is their power that is cut. The article says that, with one exception, the plants are not located in the suing states (or NYC).
Like I said, you don't have to live in the same state as a power plant in order to sue. The whole legal determination of the right to sue was turned upside down by Clintons Environmental Justice EO. It allows groups, who are not harmed by the property owners, to sue them.
It is part of the new framework that Clinton discusses in his report from the Council on Sustainable development.
These suits are an end run around the Constitution based on a subersive executive order.
Think what it would do to the grid...
