The Midday Trough Is Deepening — Week 33, 2026

Germany’s power system showed another pronounced duck-curve pattern in Week 33. Residual load fell deeply through the middle of the day before recovering sharply into the evening, creating substantial flexibility requirements. The EUnix Intelligence Platform identified Duck Curve and Flexibility Stress as the week’s leading story, with a priority score of 88.29, detection strength of 95.44%, and confidence of 80.27%. The deepest daily duck curve reached 46.3 GW, while the strongest evening recovery reached 49.9 GW.

The defining feature of Week 33 was the repeated compression of residual load through the late morning and midday period. Across the seven daily profiles, residual load generally bottomed around 11:00, with several days...

When Renewables Outran Demand — Week 32, 2026

High renewable output became the defining market force in Week 32. Renewable penetration reached 125.0% of load, residual load fell as low as -10.3 GW, and wholesale prices remained negative for 10.5 hours, reaching a weekly minimum of -€6.2/MWh. The relationship was unusually clear: renewable penetration averaged 112.3% during negative-price periods, while the price–renewable-share correlation reached -0.93. EUnix therefore ranked Renewable Surplus and Negative Prices as the week’s leading story, with a priority score of 86.95 and confidence of 76.61%.

When the Market Dips, Storage Earns: Germany’s Battery Window Widened — Week 31, 2026

Germany’s Week 31 market offered recurring battery-arbitrage opportunities as daytime prices fell toward zero before recovering sharply in the evening. The maximum daily spread reached €249.0/MWh, with 34 strong opportunity hours. EUnix ranked the story first with an 88.84 priority score. A simulated 1 MW/1 MWh battery generated €786 in gross weekly revenue across 4.0 equivalent cycles.

Midday Collapse, Evening Recovery: Germany’s Flexibility Challenge Intensified — Week 30, 2026

Germany’s power system showed a pronounced duck-curve pattern in Week 30, with deep midday residual-load suppression followed by steep evening recovery. The EUnix Intelligence Platform ranked Duck Curve and Flexibility Stress as the week’s leading story with a priority score of 88.05, detection strength of 95.32%, and confidence of 79.69%. The story-level analytics identified a maximum duck depth of 55.2 GW, a maximum evening-ramp metric of 42.0 GW, and 68 critical residual-ramp intervals.

Germany Exported More Power Overall — Yet Still Needed 15.8 GW of Imports at the Weekend — Week 29, 2026

Germany remained a strong net exporter in Week 29, yet its cross-border position changed sharply during specific hours. Imports supported the system during 43.9% of monitored intervals, peaked at 15.8 GW on Saturday, and accumulated 377 GWh across the week. The contrast between large weekly exports and concentrated import episodes highlights the growing operational value of cross-border flexibility.

Germany’s Import Reliance Intensified as Sunday Demand for Cross-Border Power Hit 16.5 GW — Week 28, 2026

Germany’s cross-border position became increasingly import-dependent in Week 28, with imports supporting the system during 50.9% of monitored intervals and peaking at 16.5 GW on Sunday. Import exposure lasted 85.5 hours, while the EUnix Intelligence Platform assigned the event a 90.11 priority score and 88.79% confidence, pointing to a material security-of-supply and cross-border flexibility story.
