ENTSOG interconnection point flow data: Europe's cross-border flows, delivered as rows

Every doorway between Europe's national gas networks reports on itself, and this is the record of what walked through. Under EU transparency rules, roughly 30 transmission system operators report operational figures for every interconnection point on their networks - plus storage facilities and LNG terminals - into one consolidated record set assembled by the European Network of Transmission System Operators for Gas (ENTSOG). Datadory delivers that record set as the ENTSOG Transparency Platform dataset: typed rows, one per indicator per point per direction per period.

The analytical appeal is grain. Most official European gas statistics stop at country-month totals; these records are point-level, direction-specific and timestamped, which is what turns "Europe imported more gas" into "this border point flowed this much in this direction on this gas day." A single verified operator-day pull illustrates the density: one query for Hungarian operator FGSZ on gas day 2026-08-18 returned 63 rows spanning border entries, aggregated storage exits and capacity products.

In Datadory's catalog the dataset scores 9/10 against a 7.81 average across 1,744 datasets - one of the strongest grades in the 16-record gas utilities slice, whose own average is 8.19. The source behind it is the industry body itself, which is about as close to primary as European flow data gets.

Each row holds one indicator for one interconnection point, one direction and one period. The indicator field spans five families:

1. Physical Flow - measured gas actually crossing the point, in kWh/d at daily grain or kWh/h at hourly grain.
2. Nomination and Renomination - the quantities shippers scheduled for the gas day, and their revisions before it.
3. Allocation - the finalised matching of flows to shippers after settlement.
4. Capacity - technical, available and booked capacity, split firm versus interruptible, plus UIOLI short-term capacity released by operators.
5. Congestion flags - isCamRelevant and isCmpRelevant mark records governed by EU capacity allocation and congestion management procedures, which makes them ready-made regime markers for any backtest.

Direction is explicit (directionKey reads entry or exit), units are stated per row, and every value carries a flowStatus such as Provisional until settlement finalises it. The verified field set runs to 34 columns, including tsoEicCode, the booking platform reference and lastUpdateDateTime.

Beyond the headline columns sit the audit fields, and they earn their space. periodFrom and periodTo bound the CET-based gas day - 06:00 to 06:00 in the verified examples - while originalPeriodFrom preserves the originally scheduled window when a renomination shifts it. Interruption reporting gets three dedicated fields (interruptionType, restorationInformation, interruptionCalculationRemark), capacity rows carry an isUnlimited flag for uncapped availability, and isNA marks gaps where an operator reported nothing. Free-text remarks fields round out the record, and pointType with isArchived lets you separate border points from aggregated storage or LNG entries before you aggregate - the single most common mistake in cross-source rollups.

The third record is the long-run static side: a capacity row for the Epe (DE) Gronau-Epe L2 storage point under Open Grid Europe reporting interruptible available capacity of zero with booking status Available, flagged unlimited, and dated from 2007-10-01. Same dataset, different decade, different question answered.

Every delivery ships with rows in this shape - typed, keyed by point and operator identifiers, units stated per row - so the sample you validate against is the schema you ship against.

European trading desks monitor cross-border physical flows, nominations and booked capacity at individual points down to hourly detail - the exact workflow the indicator set was built around, and the reason entry/exit direction matters more here than in any national aggregate.

Quant researchers backtest corridor utilisation and congestion across the 2007-onward archive, using the isCamRelevant and isCmpRelevant flags to segment periods when EU capacity-market rules changed behaviour - free regime labels most price datasets never carry.

Market researchers and energy analysts join point-level flows to country balances from Eurostat Natural Gas Supply Statistics - inland demand, import dependency, provisional 2024-2025 figures, annual series stretching to the 1970s - to explain what cross-border volumes mean nationally.

Infrastructure and GIS teams overlay asset geography from the Global Gas Infrastructure Tracker (4,158 pipelines totalling roughly 1.5 million km, 1,207 LNG terminals, 820 carriers) onto the specific border points where those assets meet the market.

Storage analysts pair flow records with tank levels from GIE AGSI+ - Aggregated Gas Storage Inventory (Europe), which tracks roughly 121 storage sites across 22 countries at daily per-gas-day grain back to 1 January 2011 - withdrawals explained by inventories, inventories explained by withdrawals.

Four neighbours cover what the interconnection point record deliberately does not, and the division of labour is clean: doorways between markets, the within-day machine inside one market, the balances of every market, the tanks, and the pipes themselves. Quality scores from the Datadory catalog frame the trade-offs - the table lines them up.

Start with the ENTSOG Transparency Platform dataset profile for the full field dictionary and sample rows, and the definitions behind the vocabulary on our glossary pages for interconnection point flows, nominations, allocations and renominations and the gas day.

Then widen the lens. The gas utilities data guide walks the whole 16-dataset slice, the head-to-head comparison with the National Gas Transmission Data Portal (UK) settles the pan-EU-versus-within-day-GB question directly, and the sibling cluster on GB linepack data covers the within-day balancing angle.

When you're ready to build, request a sample cut to the corridors, operators or points on your desk this quarter. It arrives with the field dictionary attached - and the schema in the sample is the schema you ship against.
