EU Gas Pipelines — Complete Database
108 EU internal pipelines restored · full intra-European interconnector set in the current dataset
This section now focuses on the complete EU internal pipeline list only, so users can scan every cross-border interconnector, reverse-flow corridor, and strategic redistribution route without the database being diluted by non-EU categories.
EU Internal
108
All intra-EU and connected internal redistribution corridors currently tracked in the dataset.
Operational
102
Pipelines currently usable for live redistribution, balancing, or reverse-flow support.
Under Construction
3
Projects not yet live but relevant for future market integration and resilience planning.
Constrained / Idle
3
Pipelines whose current status limits their role in practical system balancing today.
System-Level Readout
Combined named capacity
1359.8 bcm/yr
Why this matters
These are the corridors that let gas move between member-state markets when storage stress, LNG arrivals, outages, or geopolitical shocks hit one part of Europe harder than another.
Reading tip
Start with status, then route, then operator and strategic context. That sequence usually tells you whether a pipeline is a live balancing tool, a resilience backup, or a politically constrained asset.
