Protecting Renewable Energy Infrastructure
A renewable energy operator managing windfarm operations through Siemens SCADA systems required a comprehensive cybersecurity risk assessment to protect turbine operations and associated substation systems. The primary challenge was improving cybersecurity resilience while preserving the high level of reliability essential to renewable energy generation.
Operational Challenge
The operator needed a detailed cyber security risk assessment of its Siemens SCADA environment supporting turbine operations, along with connected substation systems, including RTUs and protection relays. The assessment needed to address both operational and cybersecurity risks without impacting system availability.
Our Methodology
Our team of engineers conducted a structured OT cybersecurity risk assessment aligned with IEC 62443-3-3 security requirements. The scope included review of the WPS SCADA architecture, turbine communication protocols, remote connectivity mechanisms, and substation integration points. Collaborative workshops with IT and OT stakeholders ensured comprehensive coverage across operational, engineering, and cyber security domains.
Results Delivered
- IEC 62443-3-3 Risk Assessment: Comprehensive evaluation of WPS SCADA systems, RTUs, and protection relays
- Executive Summary: Clear articulation of priority risks and compliance gaps to support leadership decision-making
- Phased Mitigation Roadmap: Strategic, risk-based action plan to systematically address identified vulnerabilities
This engagement strengthened the operator’s OT cybersecurity posture while maintaining the operational reliability required for safe and sustainable renewable energy generation.
