KKS Code - Kraftwerk Kennzeichnen System / Identification Systems for Power Plants

Updated: Aug 30, 2023

The KKS Code;

English: Identification Systems for Power Plants,

German: Kraftwerk Kennzeichnen System

was created to list the equipment in Power Plants and Refineries under a single code set by a committee convened in Germany in 1970 (consisting of engineers, suppliers, and regulators in the energy sector). It is organized based on Function, Type, and Location in accordance with ISO, IEC, and DIN 40719 Part2 (IEC750) standards.


  • It helps quickly find the type and approximate location of equipment from the P&I diagram.

  • Purchasing department facilitates communication with Engineering and Construction units.

  • It makes it easy for the cost control department to categorize costs and allows them to compare easily with other projects' budgets.
