The KKS (Kraftwerk-Kennzeichensystem) is a standardized alphanumeric system used to identify components, systems, and structures in power plants throughout their lifecycle. Developed by the VGB (Technical Association of Large Power Plant Operators), it ensures consistent technical documentation across engineering, construction, and operation. 1. Types of KKS Codes
The KKS system employs three primary coding types to cover different technical requirements:
Process-Related Code: Identifies systems and equipment according to their functional role in mechanical, civil, or electrical engineering.
Point of Installation Code: Specifically for electrical and control/instrumentation (C&I) equipment, identifying where a component is installed within a unit, such as a specific cabinet or panel.
Location Code: Identifies physical locations in structures, such as rooms, floors, or fire areas. 2. Structure of the KKS Code
KKS codes are hierarchical, typically broken down into four levels that become increasingly specific from left to right: KKS- Identification System for Power Stations
* System classification. Classification of systems and plants as per KKS Key. * E. Conventional fuel supply and residues disposal. Eskom Tender Bulletin Documentation and Licensing - vgbe energy KKS kks power plant identification system pdf exclusive
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.

KKS Power Plant Identification System (Kraftwerk-Kennzeichensystem) is the global standard for uniquely identifying systems, equipment, and components in power stations throughout their lifecycle. It provides a common language for designers, manufacturers, and operators to manage technical documentation, maintenance, and operations. Core Structure and Breakdown Levels
The system uses a hierarchical, alphanumeric code (typically 15–17 characters) structured into four distinct Breakdown Levels (BDL) Level 0: Total Plant
: Identifies the entire facility or a specific unit (e.g., "1" for Unit 1, "0" for common equipment). Level 1: Function (System Code)
: Identifies functional systems like the steam cycle (L), cooling water (P), or grid distribution (A). Level 2: Equipment Unit
: Classifies specific machines within a system, such as pump units (AP), valves (AA), or heat exchangers (AC). Level 3: Component instrumentation) Simplified maintenance planning
: Identifies individual parts of an equipment unit, such as a motor or a specific signal in control and instrumentation. Eskom Tender Bulletin The Three Mandatory Identification Types
KKS is unique because it allows for three different "views" of the same equipment using the same coding logic: KKS- Identification System for Power Stations

The KKS (Kraftwerk-Kennzeichen-System) is a standardized identification system for power plants and other industrial facilities. Originating from Germany (VGB PowerTech), it uniquely identifies components, systems, and locations across a plant's lifecycle—design, construction, operation, and maintenance.
KKS stands for Kraftwerk-Kennzeichen-System (Power Plant Identification System). Originating in Germany through VGB PowerTech, this standard (DIN EN 61346, now superseded by IEC 81346) provides a structured, hierarchical method to label every component of a power station.
Unlike ad-hoc numbering systems, KKS is universal. A valve in a coal plant in Indonesia uses the same logic as a pump in a nuclear facility in France. The system divides identification into three distinct breakdown types: and digital twin systems Supports safety

Let's analyze a realistic tag found in a typical power plant schematic:
Tag: 10LAB01AP001
Breakdown:
LAB (Civil > Building > Turbine Building)10 (Unit 1)AP (Pump)001 (The first pump)Translation: This is Pump #1 located in the Unit 1 Turbine Building.
Before labeling a single pipe, define the plant blocks. In your PDF, locate the "Grid and Plant Level" tables. You must decide if your site is a single block (e.g., 10) or multi-unit (11, 12, 13).
