Utilities now have the ability to really rate their line’s capacity. Dynamic line ratings are based on real-time measurements of sag, conductor temperature and weather conditions rather than old-school methods of selecting static conditions by committee. In addition, as more lines become brainy, the grid is morphing into a dynamic system with real-time energy management systems. These systems are capable of optimizing the electrical grid. Power flows can be monitored to avoid congestion, and software predicts the network’s behavior.
