MOD® File Builder 7.0

MOD® File Builder is a specialized application from Siemens Energy, Inc. Power Technologies International that streamlines the creation, organization, and validation of model modification (MOD) files for power system planning and analysis. It provides a guided environment to build repeatable change sets, apply them consistently to network cases, and document the rationale behind each edit. By reducing manual data entry and catching errors early, MOD® File Builder helps utilities, grid operators, and consultants accelerate study preparation for planning, compliance, and what‑if scenarios across PTI workflows (for example, PSS®E).

Key capabilities:

• Guided, template-driven authoring for consistent MOD syntax
• Real-time validation with clear diagnostics for missing references and formatting issues
• Preview, apply, and rollback of changes against baseline cases
• Batch processing to build and test multiple scenarios efficiently
• Transparent change tracking with comments, timestamps, and user attributions
• Spreadsheet import and clean, standards-based export for easier collaboration
• Searchable libraries of reusable components to standardize common edits
• Summary and audit reports to support documentation and reviews
• Optional command-line automation to integrate with existing study pipelines

Benefits include faster case preparation, fewer data errors, consistent scenario management, and traceability from assumptions to results—helping teams deliver high-quality studies on time and with confidence.
