Security requirements

ENCS develops security requirements documents to help its members and grid operators run secure systems. These documents cover specific smart grid systems, including SCADA / EMS / (A)DMS, substation automation, distribution automation, smart metering and electric vehicle charging. The procurement requirements are publicly available, while the other documents are restricted to ENCS members.

Grid operators and vendors can use these security requirements when building new systems or updating existing systems. The requirements are designed to be used with an information security management system and are aligned with the ISO/IEC 27000 standards. ENCS provides five types of security requirement documents:


The SCADA / EMS / (A)DMS security requirements cover the central systems used at control centers. They contain measures for the SCADA, EMS and (A)DMS applications, servers, workstations, and networks.

Electric vehicle charing

The electric vehicle (EV) charging requirements cover Charge Point Operator systems. They give measures for charging stations and central systems used to maintain and control them. They can be used by municipalities and provinces or others when procuring charging services.

The requirements have been developed together with ElaadNL. They hav been endorsed by E.DSO for smart grids.
