"... electricity’s share of total global energy is expected to continue to grow, and more intelligent processes will be introduced into the electric power delivery ... networks. It is envisioned that the electric power grid will move from an electromechanically controlled system to an electronically controlled network ... A key challenge is how to redesign, retrofit, and upgrade the existing electromechanically controlled system into a smart self-healing grid that is driven by a well-designed market approach."
