Enjoyable and Fascinating Info from the Problem
- Electrical energy costs confirmed distinct diurnal patterns, usually lowest round noon and Hourly value habits: Most European markets attain their lowest electrical energy costs between 12:00–14:00, and peak costs usually happen between 17:00–20:00.
- Unfavourable pricing: Germany and the Netherlands regularly skilled unfavorable electrical energy costs, usually in periods of excessive renewable technology and low demand. This happens when electrical energy provide exceeds demand, and producers are successfully paid to scale back output to keep away from overloading the grid.
- Summer season value drops: In Germany, median minimal electrical energy costs in summer time fell to round 31€/MWh, in comparison with 67€/MWh in winter.
- Excessive-price areas: Hungary, Poland, and Northern Italy recorded the highest imply hourly electrical energy costs, usually exceeding 100€/MWh.
- Seasonal tendencies: Electrical energy costs usually adopted a U-shaped seasonal sample, dipping in summer time and rising once more by means of fall and winter.
- Renewable affect: Photo voltaic and wind capability confirmed very sturdy correlations (>0.99) with electrical energy value variability, reinforcing their position in value dynamics.
- Market integration: Cross-border value correlation between Germany and its neighbors (e.g., Austria, Netherlands, Belgium, Czech Republic) exceeded 0.97, indicating excessive market coupling.
- Hydro storage utilization: Hydro pumped storage had weak or unfavorable correlations with each complete and residual hundreds, suggesting its main use is balancing slightly than regular technology.
