The electric energy grid is designed to transmit power from central generating stations, such as coal burning power plants, to areas of consumption, cities. As distributed renewable energy sources, for example rooftop solar, gain in popularity and add energy inputs to the grid from a variety of locations, this traditional design creates a challenge. Transmission lines must be updated so that they are able to transmit power from various energy sources, rather than a single generating station.
Another issue is that traditional transmission lines can only be operated at the capacity of the line that loads to full capacity first. While transmission lines may be rated to carry a large amount of electric energy, it is unlikely that most lines will ever carry their rated load. This creates a problem as traditional transmission lines could never carry the maximum output of both central generating stations and distributed renewables.
