Yes, there was. Supply and demand do have to be carefully balanced. Not an electrician but my understanding is that any imbalance starts to cause a deviation from the standard 60hz line frequency which is incredibly bad as some generating equipment will start to be “driven” by the grid while other equipment will be immediately and severely overloaded.
