What is NERC GADS?
The Generating Availability Data System (GADS) is the North American electric power industry's primary database for recording operating and performance data of power generating units.
Maintained by NERC, this data is critical for analyzing the reliability, availability, and maintainability of bulk power systems. Reporting is mandatory for conventional generating units 20 MW and larger.
3,000+
Cause Codes Supported
Data Integrity
Our engine ensures 100% adherence to NERC appendices.
Compliance
Required for most North American power generators.
Reliability benchmarking
Compare your unit's performance against industry averages.
Performance evaluation
Identify trends to improve grid stability and reduce outage duration.
Why GADS Validation Matters
NERC GADS reporting requires strict adherence to standardized cause codes, event classifications, and performance calculations. Even small inconsistencies can result in:
- Rejected submissions
- Compliance delays
- Audit risk
- Incorrect performance metrics
Manual review is time-consuming and prone to oversight.
Ellume BRIDGE automates the validation process — helping you detect errors before submission
Advanced Semantic Analysis Engine
Our system goes beyond simple format checks. We perform deep semantic and logic validation on your GADS data.
Cause Code & Event Validation
Ellume Bridge verifies event cause codes against official NERC GADS standards and detects missing, invalid, or mismatched classifications to ensure proper reporting accuracy.
Logical & Structural Consistency
Identifies logical and structural inconsistencies, impossible event sequences, and misaligned event types to ensure coherence across your report.
Data Quality & Internal Metric Checks
Ellume Bridge applies predefined domain rules and computes internal validation metrics to ensure reported values follow defined logical relationships and reporting boundaries.
Simple 5-Step Process
1. Upload
Drag and drop your prepared GADS report file (.xlsx, .csv, or .txt) into the platform.
2. Automated Validation
Our validation engine runs structured compliance, logical, and data integrity checks against NERC GADS standards.
3. Review Results
Receive a categorized error report with a detailed, line-by-line breakdown of detected issues along with contextual correction suggestions.
4. Apply Quick Fixes
Use in-platform quick-fix actions to resolve flagged issues directly within the interface, guided by validation recommendations.
5. Download Corrected Report
Export the validated and corrected report file, ready for internal review or official submission.
