About Energy Arena

Mission

Forecasting electricity prices, load, and renewable generation has become essential for power system operators, energy traders, and analysts as renewable penetration and market volatility rise across Europe. Despite a vast body of literature and notable open-access efforts, the field lacks a widely accepted, continuously updated real-time benchmark that captures the evolving conditions of modern power markets.

Energy Arena addresses this gap by providing the first open, API-driven environment where researchers and practitioners can submit day-ahead forecasts. All submissions are evaluated once actual values are published, ensuring assessment under true real-time conditions. This enables systematic comparison of forecasting solutions, quantifying real performance differences and providing an evidence-based view of methodological progress.

Why Real-Time Benchmarking?

Existing studies rely on static historical benchmark datasets, which are useful for comparing relative model performance. However, in a rapidly changing energy system, their results quickly become outdated and offer limited insight into real-time forecasting performance under current system conditions.

Furthermore, static benchmarks allow reliance on exogenous regressors that were not available at the time the forecast would have been issued, thereby overlooking key real-time forecasting constraints. At the same time, commercial forecasting solutions remain predominantly closed-source, preventing transparent quality assessment and inhibiting trust in their performance claims.

Key Features

• Real-Time Evaluation: Submissions are scored only after actual values are published
• Continuous Updates: Rolling-horizon performance metrics (last 7, 30, 90 days)
• Open & Transparent: Public leaderboards and standardized metrics
• API-Driven: Simple REST API for automated forecast submission
• Multiple Challenges: Electricity prices, load, and renewable generation forecasts
