Open data on the electricity market and the power system

Fingrid Oyj is the enterprise which takes care of the functioning of the nation-wide high-voltage grid, the backbone of electricity transmission in Finland. Fingrid produces large amount of data on the electricity market and the power system and publishes it as open data for public use. This platform provides you with tools for browsing the datasets and accessing the data free of charge and in machine readable format. You are free to utilize the data according to the license and terms of use. Fingrid encourages both individual developers and organizations to experiment with the provided datasets and publish their creations either as free or commercial products.

Fingrid's open data platform was opened as a beta service in February 2017. The platform will be developed according to the user feedback: please feel free to send us feedback by email or by using the feedback form on the features and possible problems that you may encounter.

Datasets and interfaces

Fingrid publishes data mainly on the electricity market and the power system. Datasets include both measured and forecasted data, and many datasets are updated in near real-time.

  • Platform has powerful tools for searching and browsing the datasets.
  • You can make custom searches for data within datasets. Search results can be saved and downloaded in CSV, XML or XLS formats, that can be imported e.g. to a spreadsheet application for further processing. You can download data from multiple datasets at once, provided that the time resolution is identical (e.g. 60 min or 3 min) in all datasets.
  • You can use the search and download results without registration.
  • You can access the data in machine readable format thorough open RESTful API interface. API access requires registration.
  • Data timestamps are presented in UTC (previously GMT) time format: in Finland normal time is two hours ahead and daylight saving time three hours ahead of the UTC.
  • In order to make reuse of the data as simple as possible, all data is provided without formatting, in an open and machine readable format.
