Wisdom about age [aging electricity infrastructure

This paper discusses the aging US electricity infrastructure, including generation, transmission and distribution. From the analysis in this article, there is no doubt that the U.S. electricity infrastructure is aging. Aging infrastructure has higher cost to operate and maintain and, more importantly, lower reliability. The lower reliability of aging infrastructure makes the physical system less reliable and the electricity market more risky. The healthy operation of an electricity market should take into consideration the reliability of individual infrastructure components, and one way to do that is to make the reliability a cost driver.
