A reader pointed us to this important article, written by Charlie Bayless for EEI (Edison Electric Institute). Mr. Bayless is a former provost at West Virginia University Institute of Technology and has served as CEO for several electric utilities and energy companies.
“The electric system is more than just the delivery of energy—it is the provision of reliability. First, the system must have capacity, that is the capability to furnish energy instantaneously when needed. The system also must have frequency control, retain stability, remain running under varied conditions, and have access to voltage control. Each of those essential services for reliability must come from a component on the system. Those components are not free, and they don’t just happen. They are the result of careful planning, engineering, good operating procedures, and infrastructure investment specifically targeting these items.”
