Clear identification reduces errors during maintenance,, ensuring the right component is serviced.
A standard process-related KKS code is structured across four breakdown levels, moving from macro-systems down to specific components.
It is important to note that the KKS system has a successor: the (Reference Designation System for Power Plants). KKS is the classic standard widely used in existing plants.

A KKS code is built from alphanumeric characters arranged in up to (also called data levels), each with a specific meaning.
The KKS Power Plant Identification System is the backbone of power plant organization. While the official full manual is a premium document, the general logic of the system is widely available in technical guides and engineering summaries. Mastering KKS is a fundamental skill for anyone involved in power plant design, operation, or maintenance.
However, ; KKS will continue to be used for extensions, retrofits, and I&C upgrades. About 90% of the code structure remains the same, making migration relatively straightforward.
The (Kraftwerk-Kennzeichensystem) is the global standard for coding power station equipment [1]. It provides a universal language for engineers, operators, and maintenance teams to identify every component within a plant. Managing complex industrial assets requires clear documentation.
KKS is a hierarchical system. Instead of a random serial number, each code describes what a piece of equipment does, where it is, and what it’s made of.
