TS EN IEC 63402-1

TS EN IEC 63402-1 is the standard that defines the general requirements and architecture for customer energy management systems. Its focus is the relationship between the Point of Common Coupling (PCC) and smart devices (SD) within premises-side systems in residential or commercial settings; industrial premises are outside its scope.

How the customer-side energy architecture is organised

In general technical terms, this kind of standard provides a framework for coordinating energy flows and control functions around a customer energy manager (CEM). It describes how measurement, communication and control are arranged so that the interface between the grid and the premises can be managed in a consistent way. The PCC marks the electrical boundary where energy exchange with the grid occurs, while smart devices represent the controllable loads or resources inside the premises.

What is explicitly outside the scope

• Safety requirements are not included in this standard.
• Electromagnetic compatibility (EMC) requirements are not included in this standard.
• Data security is not separately specified here, because the underlying protocols are assumed to address that aspect.
• Special equipment directly connected to the grid, bypassing the CEM, is excluded.
• Legacy heat pumps and other HBES/BACS non-enabled equipment are handled by other standards, not by the IEC 63402 series.

So, TS EN IEC 63402-1 is less about individual device performance and more about defining the boundary, roles and structure of the customer-side energy management environment. In the context of energy efficiency, its value lies in providing a common architectural basis for interoperable operation across devices and systems.
