Residual Load Drives German Power Prices as Renewable Cannibalization Intensifies - Week 2, 2026

Average day-ahead prices reached 109.291 €/MWh, with prices ranging from 29.3 €/MWh to 314.73 €/MWh. Residual load showed a strong relationship with price, with a correlation of 0.858. Renewable generation supplied 36.453% of demand on average.

Market Overview

The analysed period showed strong market sensitivity to residual load. High residual-load intervals were 77.39 €/MWh more expensive than low residual-load intervals. The maximum daily price spread reached 253.27 €/MWh, indicating relevant flexibility and storage value.
🔍

Key Observations

1 Residual load and price correlation reached 0.858.
2 136.0 scarcity intervals and 129.0 surplus intervals were detected.
3 Average scarcity price was 161.435 €/MWh compared with 68.938 €/MWh during surplus periods.
4 High renewable-share periods suppressed prices by about 69.348 €/MWh.
5 The most active physical border was FR with average absolute flow of 2345.332 MW.
🧠

Interpretation

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.
💰

Revenue Insight

The observed maximum daily spread of 253.27 €/MWh suggests strong arbitrage potential for storage assets. Scarcity intervals with average prices of 161.435 €/MWh would be attractive discharge periods, while surplus and negative-price intervals create charging opportunities.
🔭

Market Outlook

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.
