How to query data from the ENTSO-E transparency platform using Python?

A step-by-step guide to install the Python API for the ENTSO-E transparency platform and sample code on how to query data.

Most of the people working in the energy field know the ENTSO-E (European network of transmission system operators for electricity) transparency platform, which is an open-source collection of electricity generation, transportation, and consumption data for the pan-European market. Data can be downloaded directly on the platform, or by using the convenient Python API, which I will discuss here.


To use the Python API, you need to complete the following three steps:

  1. Download and install the Python client for the ENTSO-E platform first. Link to the Github repository.
  2. Register on the ENTSO-E transparency platform (click login at the top right of the page):
  3. Request an API key by sending an email to with “Restful API access” in the subject line. In the email body state your registered email address. You will receive an email when you have been provided with the API key. The key is then visible in your ENTSO-E account under “Web API Security Token”.

Once you have completed the above steps, you are ready to query data from the transparency platform with Python. It is quite handy if you want to do electricity market analysis as you get the data in tabular format and for a customizable time range. Below an example of the generation per power plant (in MW).

Query data with Python

Now let’s see how to query data from the transparency platform. Below you can find the Python code to query most of the available data. The start/end time and the respective time zone can be selected as well as the desired countries.

Important: Before executing the script you must fill in your API key as indicated!
