Import Dependency Event — Week 14, 2026

Cross-border electricity played a major role in Germany’s system operation during Week 14. Imports were present during 67.6% of monitored intervals, with a peak physical requirement of 15.72 GW and 113.5 import-dependent hours. EUnix Market Intelligence ranked the event as the #1 story of the week, with a priority score of 92.44, highlighting elevated reliance on neighbouring markets for system flexibility and security of supply.

EUnix Market Intelligence identified Import Dependency Event as the leading market story for ISO Week 14, covering 30 March–5 April 2026.

The story received a priority score of 92.44, supported by a strong detection strength of 91.84% and confidence of 88.97%.

The dominant signal was a maximum physical import requirement of 15,719.7 MW. Imports were recorded during 67.56% of monitored intervals, equivalent to approximately 113.5 hours of the reporting week.

The supporting analytics strongly reinforced the cross-border story. Import dependency scored 99.58, scheduled imports scored 94.05, and net-position analytics scored 63.76.

The weekly charts also show that import reliance was not uniform. Early in the week, several periods recorded limited or zero imports, while conditions changed significantly from Thursday onward. By the weekend, imports became both larger and more persistent.

1 Physical imports peaked at approximately 15.72 GW, the largest observed import requirement of the reporting week.
2 Germany experienced import conditions during 67.56% of monitored intervals, representing approximately 113.5 import-dependent hours.
3 The strongest import episode occurred around the weekend. The timeline shows a peak of approximately 15.7 GW early on Saturday, while the longest sustained import episode lasted roughly 32.8 hours.
4 The daily profile shows a clear late-week increase in import requirements. Daily peak imports rose from 2.4 GW on Wednesday to 12.5 GW on Thursday, 15.2 GW on Friday, 15.7 GW on Saturday and 14.9 GW on Sunday.
5 Gross weekly imported energy reached approximately 757 GWh. However, exports were even higher at approximately 953 GWh, producing weekly net imported energy of about −196 GWh. This is important: frequent import intervals did not mean Germany was a net importer over the entire week.
6 The border analysis shows a diversified import structure. Austria was the largest individual source at 21.0%, followed by the Czech Republic at 15.7% and the Netherlands at 14.5%. The top three borders collectively accounted for 51.2% of imported energy.
7 Supplier concentration remained moderate, with an import-energy HHI of approximately 1,362, suggesting that the system was not overwhelmingly dependent on a single neighbouring market.
8 Imports showed a strong negative relationship with residual load, with a reported correlation of approximately −0.84. High import periods therefore did not simply coincide with the highest domestic residual-demand conditions.
🧠
Week 14 demonstrates why import dependency should not be interpreted as the same thing as net energy dependence.

Germany imported electricity during more than two-thirds of monitored intervals and reached a substantial peak requirement of almost 15.7 GW. Yet the daily energy profile shows that total weekly exports exceeded imports.

This means cross-border exchanges were functioning dynamically in both directions rather than simply supplying a structurally energy-deficient system.

The most interesting development occurred toward the end of the week. Import requirements increased sharply from Thursday onward and remained elevated through much of the weekend. Saturday produced the maximum physical import requirement, while Sunday also recorded sustained high import levels.

At the same time, the strong negative correlation between imports and residual load suggests that domestic demand pressure alone does not explain these flows. Cross-border price differentials, renewable availability, market coupling, neighbouring-system conditions and scheduled commercial exchanges may all influence whether electricity moves into or out of Germany.

The distinction is therefore important: Week 14 was characterised by high operational reliance on cross-border flexibility, but not by overall weekly net import dependence.

The diversified supplier mix is also relevant from a security-of-supply perspective. Austria was the largest individual source, but its 21% share was not dominant, and the top three suppliers represented only about half of total imported energy. This reduces exposure to disruption at any single border.
💰
Import-dependency events create commercial opportunities, but unlike battery arbitrage, there is no single revenue figure that can be inferred directly from physical flow data. The main value arises through cross-border trading, congestion management, flexibility provision and market-price convergence. During Week 14, the strongest commercial opportunities would likely have been concentrated around periods when Germany required large physical imports, particularly from Thursday through Sunday. Market participants able to anticipate these periods could potentially benefit from cross-border price differences, transmission rights, flexible generation, storage or demand-response positions. The supplier distribution is also commercially relevant. With Austria, the Czech Republic, the Netherlands, Poland and Switzerland all contributing meaningful volumes, trading opportunities were distributed across several interconnected borders rather than centred on a single route. However, physical import intensity alone should not be treated as evidence of trading profit. Actual revenue depends on day-ahead and intraday price differentials, transmission constraints, capacity allocation, balancing prices and the cost of securing cross-border positions. Those variables would need to be analysed alongside the flow data before any revenue estimate could be made. For Week 14, the stronger conclusion is that sustained cross-border dependence created significant market relevance, particularly during the late-week import escalation.
🔭
The key question for subsequent weeks is whether the late-week import pattern observed in Week 14 becomes persistent or returns to a more balanced cross-border profile.

Particular attention should be given to import-dependent hours, peak physical imports, scheduled imports, residual-load conditions, supplier concentration and border-level contributions.

If import peaks continue to exceed 15 GW while import-dependent hours remain elevated, Germany's reliance on neighbouring systems for short-term operational flexibility would remain significant.

However, the Week 14 data also demonstrate that high import frequency can coexist with strong exports. Future analysis should therefore continue separating three different concepts:

frequency of import conditions
magnitude of peak import requirements
net weekly import/export energy balance

Tracking those dimensions separately provides a more accurate picture of cross-border security and market dependence than any single import metric alone.
