Open data

Our figures, as open data

Every figure we quote has a source and a licence. Here they are in one place: as JSON, as CSV and with an explanation per field. No account, no API key.

  • One source

    The same feed drives the page on joulo.nl and the dataset. What you fetch here is what we show ourselves.

  • Provenance per field

    Every feed states per field where the figure comes from: verbatim from the source, calculated by us, or from our own records.

  • What is left out

    We do not publish counts of chargers or charging sessions. Distributions are given as shares in percent, customer counts rounded up to 500.
