For grid-scale battery energy storage systems (BESS), renewable energy infrastructure, and critical power networks, Panasonic Holdings Corporation and Panasonic Solution Technologies Co., Ltd., in collaboration with ITOCHU Corporation, have launched a cybersecurity monitoring demonstration under conditions representative of actual grid operations. The initiative introduces a monitoring solution designed to detect anomalies in communications and control systems, addressing emerging cybersecurity risks in increasingly digitalized energy environments.
The trial represents the world’s first*1 demonstration of cybersecurity monitoring applied to grid-scale BESS under real operational conditions.
Addressing cybersecurity risks in interconnected energy systems
As renewable energy adoption increases, power generation, transmission, and consumption systems are becoming more interconnected and software-driven. While this improves operational flexibility, it also expands potential entry points for cyberattacks.
Incidents involving unauthorized access to solar power facilities and disruptions caused by advanced attack techniques have highlighted the limitations of traditional perimeter-based security measures*2 such as firewalls. These approaches are less effective against threats originating in internal networks or attacks that mimic legitimate system behavior.
Grid-scale BESS introduce additional risks due to their active role in balancing supply and demand through charge/discharge control and output regulation. A compromised system could affect grid stability beyond a single installation, impacting wider energy infrastructure.
Monitoring solution combining signature and behavior-based detection
The demonstration deploys a cybersecurity monitoring solution that integrates signature-based detection of known threats with behavior analysis tailored to power-control communications. This dual approach enables the identification of both established attack patterns and anomalies specific to energy management systems.
Unlike conventional IT security tools, the system incorporates detection logic adapted to protocols and command behaviors used in BESS operations. This specialization improves the ability to detect irregularities in control signals and system interactions that may indicate cyber threats.
Simulated attack scenarios for validation
To evaluate system performance within the limited timeframe of the demonstration, simulated cyberattacks are conducted under controlled conditions.
On-site testing involves direct interaction with the facility’s internal network, generating scenarios such as unauthorized device connections and manipulation of control parameters. Off-site testing simulates external attack vectors, including unauthorized remote access and advanced intrusion techniques.
Data collected during these simulations is used to assess detection accuracy, response capabilities, and operational effectiveness of the monitoring solution.
Establishing benchmarks for cybersecurity in energy infrastructure
Validating cybersecurity technologies in live BESS environments presents technical challenges due to the need to maintain grid stability and operational safety. By conducting testing under realistic operating conditions, the project aims to define practical benchmarks for cybersecurity assurance in mission-critical energy systems.
The integration of communication monitoring and behavior-based analysis represents a shift toward multilayered defence strategies, which are increasingly required to address complex cyber threats in distributed energy networks.
Supporting secure deployment of future energy systems
Insights gained from the demonstration will inform the development of cybersecurity frameworks for grid-scale storage and broader energy infrastructure. The results are expected to support compliance with industry standards and contribute to safer deployment of distributed energy resources.
As digitalization and decentralization continue to reshape energy systems, integrating cybersecurity into infrastructure design becomes essential for maintaining reliability and resilience across power networks.

*2 A conventional security approach primarily focused on controlling communications at network boundaries.
