Root Cause Analysis
Clarity on What Failed, Why It Happened, and What to Do Next
What is it?
Root Cause Analysis is a rigorous, structured investigation designed to move past symptoms and uncover the “why.” The process integrates field measurements, historical performance data, and forensic documentation to pinpoint the exact origin of a failure.
Why is it important?
Performance issues—such as recurring defects, accelerated degradation, or localized anomalies—are often treated as isolated events.
In reality, they often originate earlier in manufacturing, transport, installation, or system design. Without identifying the cause, issues repeat, spread across the system, and lead to energy losses, higher costs, and weaker warranty positions.
The STS Approach
How can STS help?
STS conducts a comprehensive technical investigation that links observed issues to their source. By combining advanced on-site inspections and performance data analysis, STS isolates failure mechanisms, defines the scope of impact, and assesses technical responsibility.
Findings are delivered in a detailed, evidence-backed report that supports corrective action and provides defensible positioning for warranty claims and dispute resolution.
When is it used?
Root Cause Analysis is essential during the operational phase when systems fail to meet yield expectations, defects reoccur, or patterns of underperformance emerge without obvious cause.
It is most commonly used by Independent Power Producers (IPPs), EPC contractors, project developers, and asset owners/operators responsible for system performance and financial outcomes.
