Each of the systems has had its own romantic growth from the small local generating plant to the highly developed load area with its network of power lines furnished by modern power stations. It was proper then that these independent neighboring companies should cooperate to realize the benefits of interconnection. These benefits now are being secured, the common understanding of every day problems of parallel operations being secured through the working committee of operating men from each of the ten individual systems.
