ECMWF produces and disseminates weather forecast data for the National Meteorological and Hydrological services (NHMSs) of ECMWF member and co-operating states and their authorised users. The data are released 1 hour after the real-time dissemination schedule. A Python package called ecmwf-opendata is available from PyPi that greatly facilitates the access to this dataset. In addition, a series of Jupyter Notebooks have been developed to demonstrate the use of this package.

Disclaimer: ECMWF does not accept any liability whatsoever for any error or omission in the data, their availability, or for any loss or damage arising from their use.

This dataset contains average hourly, daily and monthly wholesale day-ahead electricity prices for European countries. Hourly data is provided as a .zip file to reduce download size. Note that these are the prices generators receive for selling electricity on the spot market. They are not the same as the prices paid by electricity consumers, which can also include taxes, levies, network charges, subsidies, and some supplier profits. They also do not account for hedging.
