New IEEE Standard - Inactive-Withdrawn. This recommended practice provides a single source of fossil-fuled power plant system descriptions which, along with related recommended practices concerning unique identification principles and definitions, component function identifiers, and implementation instructions, makes up a concept for uniquely identifying systems, structures, and components of fossil-fuled power-plant projects (electric power generating stations) and related facilities. Nuclear, hydro, and other types of power plants are not included in this recommended practice.
