Dataset description

Annual national evolution of the lengths (km) of circuits in operation of the electricity transmission network by voltage level (63 kV, 90 kV, 225 kV, 400 kV, ...) and by nature of evolution (new infrastructure, renewal, undergrounding, scrap, other modifications). The types of development of a section are: * New: when the installation of the section is re-routed (e.g. a new link) * Renewed: when an air section is replaced by an air section or when an underground section is replaced by an underground section * Underground: when an air section is replaced by an underground section * Scrap: when the section has been physically removed from the network * Other changes: these are all variations in length not recorded in new and scrapped sections. This mainly concerns sections placed in reserve (disconnected from the network but still in place) but also error or length corrections * * *

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.

Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.

Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.

Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
