TS 7718

TS 7718 is a terminology standard for the terms and definitions used in the generation, transmission and distribution of electric power, with this part focused on generation. It provides a common vocabulary for power stations, generating installations, generating equipment, and the operation of power stations. In technical work, terminology standards help different organisations use the same engineering words with the same meaning, which improves clarity in documentation and communication.

How generation terminology is organised

Electricity generation is the process of converting energy from mechanical, thermal, hydraulic, nuclear, or renewable sources into electrical energy. In practice, this involves not only the generating unit itself but also associated equipment, station arrangements, and operating concepts. The scope of this standard is the terminology used in that field; it establishes the names and definitions of the concepts rather than describing design methods or operating procedures.

Why the distinction matters

When generation is considered together with transmission and distribution, a shared terminology becomes essential for describing how electrical power moves through the system. Expressions such as power station, installation, operating practice, and generating equipment refer to different layers of the same technical environment and are important in design documents, specifications, maintenance records, and operating instructions. TS 7718 is based on IEC 60050-602:1983, placing it within the international electrotechnical vocabulary tradition.

• Standardised terms and definitions for electricity generation
• Common vocabulary for power stations and generating installations
