ONS Brazil Open Data

ONS Brazil Open Data

Brazil's grid operator (Operador Nacional do Sistema Elétrico, ONS) publishes an open data portal (dados.ons.org.br) covering load, generation by source, reservoir levels and interchange/transmission data, via a CKAN API and S3-hosted CSV/XLSX/Parquet files.

Coverage

Brazil's national interconnected system: hourly/daily load, generation by source, reservoir levels, interchange and transmission data. The sampled carga-energia dataset's CKAN metadata gives "Schedule de Atualização": "Diariamento, as 12h e 19h" (Portuguese; Signal Lab translation: "Update schedule: daily, at 12h and 19h"), and its resource list runs from Carga_Energia-2000 through the current year. Signal Lab does not generalize this cadence to every ONS portal dataset.

Verdict

CKAN API and S3-hosted CSV/XLSX/Parquet files (dados.ons.org.br) for Brazil's grid operator (ONS) load, generation-by-source, reservoir-level and interchange/transmission data. Licensed Custom: the CKAN package metadata's license_id is "cc-by" with no version stated, and the site's own notice says (Portuguese; Signal Lab translation in brackets): "Ao acessar este site e/ou utilizar as informações provenientes dele, será considerado que você aceitou os termos e condições da LICENÇA CC-BY, que permite que os reutilizadores distribuam, modifiquem, adaptem e desenvolvam o material sobre os dados, desde que seja dado o crédito apropriado ao criador(ONS) e que informe quais alterações foram feitas." [By accessing this site and/or using the information from it, you will be considered to have accepted the terms and conditions of the CC-BY LICENCE, which allows reusers to distribute, remix, adapt and build upon the material on the data, provided that appropriate credit is given to the creator (ONS) and that any changes made are stated.] Signal Lab does not generalize this to CC-BY-4.0 because neither the site nor the CKAN metadata states a version number. Rate limits: Not stated. Signal Lab links only.
