Lightning Risk Assessment for Critical Infrastructure
Data-driven analysis that turns lightning risk into informed investment decisions.
How much risk is your facility actually carrying? Without a quantitative assessment, lightning protection decisions are based on assumptions — leading to either under-protection that leaves critical systems exposed, or over-investment in measures that don’t deliver proportional risk reduction.
Aetheric’s risk assessments replace guesswork with precision. We quantify the probability and consequences of lightning strikes to your facility, identify specific vulnerabilities, and demonstrate the economic justification for every recommended protection measure. The result is a clear, defensible basis for capital allocation — backed by real lightning data and internationally recognised methodology.
Understand Your Lightning Risk
Find out where your facility is exposed and what it would take to bring risk within tolerable limits.
Service Overview
Lightning risk assessment provides the analytical foundation for protection system design by quantifying the probability and consequences of lightning strikes to facilities. Rather than applying generic protection measures, risk assessment enables targeted, cost-effective solutions appropriate to each facility's specific exposure and criticality. This approach ensures protection investments are justified by measurable risk reduction while avoiding unnecessary over-design.
Aetheric conducts comprehensive risk assessments following internationally recognized methodologies, incorporating facility-specific parameters, local lightning activity data, and consequence analysis to calculate risk values for comparison against tolerable risk criteria. Our assessments identify specific vulnerabilities, quantify potential losses, and demonstrate the economic justification for proposed protection measures.
Advanced Assessment Methodology
Aetheric utilizes Skytree Scientific's LRA Plus platform for lightning risk assessment, leveraging AI-powered calculations and real-time lightning location system (LLS) data to deliver precise, standards-compliant analysis. This advanced software automates complex multi-variable calculations required by IEC 62305-2, AS/NZS 1768, and NFPA 780 Annex L, significantly reducing assessment time while improving accuracy and consistency.
The platform processes actual lightning flash density and strike point density data for the facility location, eliminating reliance on outdated keraunic level metrics. Risk calculations account for structure characteristics, connected services (power lines, telecommunications, pipelines), internal systems including surge protection measures, and consequence factors including human safety, service continuity, cultural heritage, and economic impact.
Our risk assessment methodology evaluates multiple risk components including injury to living beings (R1), loss of service to the public (R2), loss of cultural heritage (R3), and loss of economic value (R4). Each component is calculated based on the probability of lightning strikes, the probability of damage (accounting for existing protection including SPD installations), and the subsequent loss. This comprehensive approach enables precise quantification of overall facility risk and identification of dominant risk contributors.
Data Integration & Analysis
Aetheric integrates multiple data sources to ensure assessment accuracy. Historical lightning strike data from ground-based detection networks provides precise flash density measurements for the facility vicinity. Facility parameters including structural dimensions, materials, occupancy, and operational characteristics are systematically documented through site surveys and client interviews. Equipment inventory and consequence analysis quantify potential losses from various failure scenarios.
The assessment evaluates both direct strikes to the structure and indirect effects including strikes to connected services and strikes near the structure causing electromagnetic interference. Protection measure effectiveness including external protection systems and internal SPD installations is quantified, allowing evaluation of various protection scenarios and optimization of the protection system design.
Regulatory Compliance
Our risk assessments comply fully with IEC 62305-2 methodology, which is recognized globally as the authoritative framework for lightning risk analysis. For facilities in New Zealand and Australia, we apply AS/NZS 1768:2007 requirements. For facilities in regions following NFPA 780, we apply the Annex L risk assessment procedures. Regional variations and local authority requirements are accommodated through our knowledge of international standards and regulatory frameworks across New Zealand, Australia, ASEAN, and MENA regions.
Risk assessment documentation demonstrates due diligence for liability purposes and provides justification for capital expenditure on protection systems. For regulated industries, our assessments support compliance with safety management system requirements and asset integrity programs.
