Jun 1, 2025June 2025 monthly summary for gridstatus/gridstatus. Focused on expanding real-time and forecast data integrations for major North American markets (AESO and CAISO), increasing data fidelity, reliability, and performance, while improving naming consistency and tests to support maintainability and faster delivery of business insights. Key outcomes: - Expanded AESO data integration and retrieval: market data, load data, outages, forecasts, and rolling statistics with minutely intervals; introduced minutely AESO price series (including pool price, forecast pool price, and system marginal price); added AESO load and load forecast; included unit status, outages, and renewable forecasts; introduced AESO daily average price and 30-day rolling average; improved data alignment to support near-term decision making and price risk management. - CAISO data integration: added Real-Time Dispatch/Performance data (RTD, RTPD) and hourly actuals, with refactor and test coverage to ensure reliability of market intelligence and forecasting. - API naming clarity and internal refactor: standardized ISONe API naming (get_hourly_load_forecast -> get_load_forecast_hourly) and updated tests/cassettes for consistency, reducing confusion and simplifying usage. - Performance and reliability improvements: implemented multithreaded data fetching for IESO predispatch, enabling parallel URL processing and significantly reducing data fetch latency. Overall impact: - Broader visibility into key market signals across AESO and CAISO, enabling faster and more accurate trading, risk management, and operational planning. - Increased data freshness (minutely pricing and outages), improved forecast accuracy, and end-to-end data quality with better test coverage and maintainability. - Clearer API surface and refactoring that reduce onboarding time for new developers and improve long-term scalability. Technologies/skills demonstrated: - Python data pipelines, API integration, and data modeling; multithreading for performance; test-driven development and refactoring; cross-market data orchestration; attention to data lineage (pricing, load, outages, and forecasts).
