The Midday Trough Became an Evening Flexibility Test — Week 37, 2026

Germany’s residual-load profile became a pronounced flexibility challenge in Week 37. The EUnix Intelligence Platform identified a 52.8 GW maximum duck depth, while the strongest interval-level upward ramp reached 21.2 GW/h. The system recorded 68 critical residual-ramp intervals, as deep daytime depressions repeatedly gave way to steep afternoon and evening recovery. The story ranked #1, with a priority score of 89.66 and confidence of 82.48%.

Week 37 displayed the classic mechanics of a duck curve: renewable generation increased strongly through the morning, residual load fell toward midday, and the system then had to recover rapidly as renewable output decli...

Germany Spent Five Days Leaning on Imports — Week 36, 2026

Germany’s cross-border dependence intensified in Week 36. Imports were present during 71.7% of monitored intervals, or 120.5 hours, with physical imports peaking at 13.91 GW. Weekly imported energy reached 830 GWh, exceeding exports of 664 GWh by about 167 GWh. EUnix Intelligence ranked the Import Dependency Event #1, with a 91.46 priority score and 87.46% confidence.

When Imports Become the Safety Net — Week 35, 2026

Cross-border electricity became a key feature of Germany’s system in Week 35. Imports were required during 69.0% of monitored intervals, or 116 hours, and peaked at 16.89 GW. Yet Germany remained a net exporter over the week, with 787 GWh exported against 742 GWh imported. This highlights a key distinction: strong hourly import dependence can coexist with a weekly net-export position. EUnix Intelligence ranked the Import Dependency Event #1, with a priority score of 92.97 and confidence of 88.98%.

The Forecast Was Wrong — But the System Risk Was Bigger | Week 34, 2026

Germany entered Week 34 with a clear forecasting problem: generation forecasts missed realised output by 4.69 GW on average, while the largest error reached 29.29 GW. At the same time, schedule deviation climbed to 31.56 GW, creating elevated operational exposure. EUnix ranked Forecast Failure and Balancing Risk as the week’s #2 story, with a priority score of 85.58 and 77.44% confidence.

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.

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%.
