“There’ll come a degree the place it will likely be a go or no go determination however the plan in the mean time is to make use of it for the night.
“This isn’t about blackouts. The purpose is that we will all the time get or produce extra electrical energy. That is about giving folks extra flexibility and giving the grid extra flexibility.”
