RDS-PP® (Reference Designation System for Power Plants) is the newer international standard based on ISO 81346-10 and is intended to replace KKS in the long term. KKS is still used for existing plants, while RDS-PP® is being adopted for new projects.
The KKS system is a standardized nomenclature used to identify plants, sections of plants, and items of equipment in any type of power station. Whether it is a nuclear, thermal, hydro, or renewable energy facility, KKS ensures that every single component—from a massive steam turbine to a tiny limit switch—has a unique, unambiguous alphanumeric code. Why Standardized Identification Matters
Narrow down the subsystem (e.g., HA might denote the pressure system of a boiler). Numbers: Differentiate between identical systems or loops. Level 2: Equipment (Equipment Unit Code)
Identifies the specific machine, pump, or valve within that system. : 2 letters and 3 numbers (AA001, AP002). Key Letter Categories : AA : Valves, dampers, gates AP : Pump units AT : Transformer units Breakdown Level 3: Component Identifies the exact part, sensor, or electrical terminal. Format : 2 letters and 2 numbers (KP01, XB01). Key Letter Categories : CE : Electrical drive components KP : Instrumentation/sensors Real-World KKS Coding Example kks power plant identification system pdf free

KKS uses three distinct types of codes to categorize plant assets:
Official, comprehensive guidelines from VGB are primarily distributed under copyright. However, many major international engineering, procurement, and construction (EPC) companies publish their own abridged KKS standards and project-specific handbooks.
