Residual Load Drives German Power Prices as Renewable Cannibalization Intensifies - Week 1, 2026

Average day-ahead prices reached 73.55 €/MWh, with prices ranging from -49.0 €/MWh to 288.2 €/MWh. Residual load showed a strong relationship with price, with a correlation of 0.625. Renewable generation supplied 64.172% of demand on average.

📊
The analysed period showed strong market sensitivity to residual load. High residual-load intervals were 75.48 €/MWh more expensive than low residual-load intervals. The maximum daily price spread reached 337.2 €/MWh, indicating relevant flexibility and storage value.
🔍
1 Residual load and price correlation reached 0.625.
2 113.0 scarcity intervals and 138.0 surplus intervals were detected.
3 Average scarcity price was 127.365 €/MWh compared with 13.903 €/MWh during surplus periods.
4 38.0 negative-price 15-minute intervals occurred, with the lowest price at -49.0 €/MWh.
5 High renewable-share periods suppressed prices by about 76.564 €/MWh.
6 The most active physical border was CH with average absolute flow of 2508.219 MW.
🧠
The market behaviour indicates a clear scarcity-surplus structure. When renewable output was high, prices were significantly reduced. When residual load increased, prices rose sharply. This confirms that flexible assets such as batteries, demand response, and controllable load can capture value from both scarcity and surplus periods.
💰
The observed maximum daily spread of 337.2 €/MWh suggests strong arbitrage potential for storage assets. Scarcity intervals with average prices of 127.365 €/MWh would be attractive discharge periods, while surplus and negative-price intervals create charging opportunities.
🔭
If renewable penetration remains high, further price cannibalization and negative-price intervals are likely. However, the strong relationship between residual load and prices indicates that flexibility value will remain high, especially during evening ramps and low-renewable periods.
