Penetration Testing for Energy & Utilities
Renewable energy companies — including wind, solar, battery storage, EV charging, and smart grid operators — face unique cybersecurity challenges as the energy transition accelerates. These organisations operate increasingly connected operational technology (OT) environments that control power generation, grid management, and distributed energy resources across wide geographic areas.
The convergence of IT and OT in renewable energy creates attack surfaces that span SCADA systems, inverter controllers, battery management systems, weather forecasting platforms, energy trading systems, and customer-facing portals. Nation-state actors and cybercriminals increasingly target renewable energy infrastructure as its share of the grid grows and its disruption potential increases.
Penetration testing for renewable energy must address both traditional IT systems and the specialised OT environments that control physical assets. Testing must be carefully coordinated to avoid disrupting energy generation or grid stability. Compliance with NIS 2, IEC 62443, and national energy regulations requires regular security assessment of both IT and OT environments.

Energy & Utilities Pen Testing FAQs
What renewable energy systems need penetration testing?+
Priority systems include SCADA and energy management systems, inverter and battery controllers, smart grid infrastructure, remote monitoring platforms, energy trading systems, and customer portals. Both IT and OT environments should be tested.
Can wind farms and solar installations be safely pen tested?+
Yes, with specialist OT pen testers who understand energy systems. Testing uses passive techniques on live production systems and may use offline replicas for active exploitation testing to avoid disrupting generation.
What regulations apply to renewable energy cybersecurity?+
NIS 2 covers energy as an essential sector in the EU. IEC 62443 provides industrial cybersecurity standards. National energy regulators often have additional requirements for grid-connected systems. NERC CIP applies in North America.
