The KKS (Kraftwerk-Kennzeichensystem), developed by vgbe energy, is the global standard for identifying and classifying systems and components in power plants. It provides a standardized, hierarchical, and alphanumeric code system to facilitate consistent documentation and data processing across electrical, mechanical, and civil disciplines.

The operation of a power plant, whether fossil-fueled, nuclear, or renewable, involves the management of hundreds of thousands of individual components. Without a standardized naming convention, the resultant chaos would pose severe risks to operational safety and efficiency. A valve labeled simply "V-1" in one drawing might be duplicated elsewhere, leading to catastrophic maintenance errors. It is within this context that the KKS identification system emerged. Developed in Germany during the 1970s by the VGB PowerTech organization, KKS provides a structured, alphanumeric coding system capable of identifying equipment with absolute precision. While proprietary systems exist, the ubiquity of KKS documentation—often disseminated through technical PDF manuals—underscores its status as the lingua franca of the power generation industry.
