The Clean power plan provided a structure to the transition from the antiquated generation and distribution systems of a century ago to the systems of the future that will be cheaper and more reliable.
Grid structure with distributed generation and storage combined with more efficient us of long distance transmission will lead to a structure that will have only small areas of disruption.  Using primarily zero fuel cost and low maintenance systems combined with some automation will make energy very inexpensive.
