Management of network assets in power systems - Part 1: Overview, principles and terminology

Scope

IEC 63223-1:2026 provides an overview of asset management, its principles and value creation options for the management of network assets in power systems.
This document can be applied to all types of network assets and by all types and sizes of power network companies. The term power network company does not necessarily refer to legally structured companies.
In this document, network assets refer mainly to the physical assets of the electrical energy network, meaning items, equipment, or systems that have potential or actual value for the electric company and are part of the power lines and substations responsible for the transmission and distribution of electrical energy. Examples of network assets that can be included in the asset portfolio of a power network company are presented in IEC 63223-2:2026, 4.2.2.
