Synopsis

The global surge in Battery Energy Storage Systems (BESS) has triggered a new wave of regulatory scrutiny, as governments push for safer and more resilient energy infrastructures. Frameworks like the UK Cyber Assessment Framework (CAF) and the EU NIS 2 Directive are now redefining what accountability truly means—placing the responsibility directly on asset owners and operators to prove their governance, resilience, and operational assurance.

Yet, while regulation is tightening, cybersecurity remains the blind spot in many BESS strategies. Asset managers are busy ticking compliance boxes but overlooking the real risks embedded in operational technology (OT), remote access, and third-party integrations. The result: compliant on paper, but exposed in reality—and when an incident occurs, it’s the owner’s name on the line.
