The Engrate Schedule Management API provides a unified, modern RESTful interface for submitting energy schedules to Transmission System Operators (TSOs) across Germany and the Netherlands. We handle all the complex, market-specific integration requirements behind the scenes, allowing you to work with a single, consistent API regardless of whether they’re submitting schedules to German TSOs (Amprion, 50Hertz, TenneT, and TransnetBW) or the Dutch operator TenneT. Our platform automatically manages the different protocol requirements, data formats, and validation rules for each market - from EIC codes in Germany to participant IDs in the Netherlands. Built with developer experience in mind, the API includes comprehensive versioning, real-time status tracking, and complete audit trails. This means you can focus on building your energy management applications while we ensure reliable, compliant schedule delivery to TSOs.

​
Key Features:

  • Multi-Market Support: Single API endpoint automatically handles both German and Dutch market requirements, with built-in validation and format creation for each TSO’s specific protocols.
  • Intelligent Version Management: Full version control system with automatic tracking of schedule modifications, allowing retrieval of historical versions and complete change history for regulatory compliance.
  • Real-Time Status Tracking: Monitor schedule acceptance status in real-time with detailed feedback from TSOs, including preliminary, final, and settled acceptance levels, according to each TSO’s ruleset.
  • Time Series Flexibility: Support for multiple aggregation types and resolutions (15-minute, hourly, daily intervals) with automatic handling of timezone conversions and daylight saving time transitions.
  • Enterprise-Ready Security: Engrate APIs use industry-standard OAuth 2.0 for secure authentication and authorization and comprehensive audit logging.

Developer & Operations Tools

Beyond the API, Engrate provides a comprehensive suite of tools to streamline development and operations. Our debugging tools allow you to trace and troubleshoot schedule submissions in real-time, identifying any validation issues or TSO responses before they impact production. The Schedule Management Dashboard gives you a visual overview of all your schedules across both markets, with filtering, search, and detailed status tracking capabilities. Additionally, our Audit Tools provide complete transparency with searchable logs of all API interactions, schedule modifications, and system events, ensuring you maintain full compliance and can quickly investigate any issues. Full access to the raw schedule data makes the tool complete. Schedule tool
