Too much of a good thing, or as they say, unintended consequences, is pushing the grid in some places toward instability. By the way, I scoff at the term “unintended consequences.” There are only two types of consequences: intended and ignorant ones.Utility Dive notes that Texas (Electricity Reliability Council of Texas – ERCOT) and the Southwest Power Pool are the…
