NIS2 and PV plants: new requirements for monitoring and system control

The NIS2 Directive significantly raises the requirements for operators of energy infrastructure. Utility-scale PV plants are also coming more into the focus of regulatory responsibility. Whether an operator falls under NIS2 depends, among other things, on company size and activity.

Existing monitoring structures are reaching their limits

Monitoring, access control and data security are increasingly becoming prerequisites for secure plant operation. However, many existing PV plants still work with system structures that have grown over time:

• separate systems
• fee-based legacy portals
• limited rights management
• a lack of transparency about system access

This makes operation more difficult and becomes a risk under the new regulatory requirements.

Why NIS2 matters for PV operators

NIS2 raises the requirements for:

• traceable system access
• clear role and rights management
• secure communication structures
• transparent monitoring systems

Monitoring thus changes from an add-on to a central part of critical infrastructure.

Modern system architecture as the foundation

A future-proof PV infrastructure needs a clear system structure:

• central control and monitoring
• secure communication between components
• integrated monitoring and control systems

REFUlink provides the interface between inverters, grid requirements and monitoring.

Central integration and transparent system control

With REFUlink and REFUview, plants can be

• centrally monitored and controlled
• integrated into existing systems in a structured way
• documented in a traceable manner.

State-of-the-art security: REFUlink and REFUview support operators in meeting NIS2 requirements, with hosting and data processing in Germany as well as user and access management.

Many existing plants can also be migrated to a modern monitoring and communication structure with manageable effort.
