transmission system operator (TSO)
transmission system operator (TSO) is company that operates a national or regional gas transmission network; source_name records "European Network of Transmission System Operators for Gas (ENTSOG)". In Datadory's catalog of 1,744 datasets, source_name and coverage are working examples. Conventions like this decide whether two sources can be joined cleanly.
What is transmission system operator (TSO)?
The company that operates a national or regional gas transmission network.
ENTSOG's transparency platform aggregates flow, nomination and capacity data from roughly 30 EU and connected non-EU TSOs, identified by codes such as UA-TSO.
In this catalog it appears concretely: - source_name — "European Network of Transmission System Operators for Gas (ENTSOG)". - coverage — "All EU member state transmission systems plus connected non-EU TSOs participating in the platform (e.g. Ukraine".
coverage is the second reference point worth knowing: "All EU member state transmission systems plus connected non-EU TSOs participating in the platform (e.g. Ukraine". Reading the two together shows how much variation sits underneath one shared label.
Why does transmission system operator (TSO) matter when choosing a dataset?
Conventions decide whether two sources can be joined at all. Buy one side of an analysis that ignores this convention and every reconciliation step — calendar alignment, unit conversion, entity matching — lands on your team instead of the vendor's.
The failure mode is concrete: a source can carry the transmission system operator (TSO) label while differing from what you need on exactly the dimension that matters — European Network of Transmission System Operators for Gas (ENTSOG). Comparing two sources on that line usually settles the choice faster than any feature matrix.
You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and source_name lets you inspect the real artifact before any budget is committed.
How do you evaluate transmission system operator (TSO) in a data source?
Treat every claim of this attribute as testable:
- Open source_name and confirm its record — "European Network of Transmission System Operators for Gas (ENTSOG)" — against the files you actually receive.
- Open coverage and confirm its record — "All EU member state transmission systems plus connected non-EU TSOs participating in the platform (e.g. Ukraine" — against the files you actually receive.

Frequently asked questions
What is an example of transmission system operator (TSO)?
source_name is the clearest example in this catalog. Its record states: "European Network of Transmission System Operators for Gas (ENTSOG)". Across all 1,744 datasets Datadory averages a quality score of 7.81 out of 10, so a named example can be weighed rather than trusted blindly.
Is data described as "transmission system operator (TSO)" free to use?
Treat access and permission separately. 82.4% of the 1,744 datasets in this catalog are free to access, but 235 are freemium and 61 are paid outright, so confirm both the price and the license on the exact distribution before building on it.
How do I verify a source really provides transmission system operator (TSO)?
Open source_name next to coverage and compare the promise with the download. Field definitions are verified for 1495 of 1,744 datasets (85.7%), which makes that check fast inside the catalog and manual outside it.
