arXiv:2606.09517v1 Announce Type: new Abstract: As renewable energy integration increases market volatility, probabilistic electricity price forecasting has become essential for effective risk management. However, current-proper-scoring rules often prioritize forecast sharpness at the expense of calibration, leading to overconfident and statistically unreliable uncertainty estimates. This work highlights the critical gap between theoretical scoring and practical calibration, demonstrating that models can become mere proxies for deterministic forecasts when reliability is neglected. We conclude
The increasing integration of renewable energy sources is driving market volatility, making accurate probabilistic forecasting crucial for grid stability and economic efficiency.
Reliable electricity price forecasting is essential for risk management, investment decisions, and the stability of energy markets in an increasingly renewable-dependent grid.
The focus is shifting from mere forecast sharpness to improved calibration in probabilistic models, aiming for more reliable uncertainty estimates that better reflect real-world conditions.
