Monthly Electricity Statistics

This dataset, updated monthly, provides electricity production and trade data for OECD Member Countries and electricity production data for a selection of other economies.

An interactive data explorer is also available.

.Stat Explorer and SDMX

Since March 2026, Monthly Electricity Statistics (MES) dataset has been available through the .Stat Data Explorer. This platform allows users to view the data and export it in Excel and CSV formats. 

As part of this transition, the IEA has carried out a harmonisation process to align codes and naming conventions across all agency data dissemination in .Stat. As a result, some dimensions and most of the codes previously used in the legacy MES CSV file differ from those used in the SDMX-based dissemination format. This harmonisation improves internal consistency and allows datasets to be used together more easily. To support users during this change, an Excel file mapping legacy CSV codes to the new harmonised codes is available in the documentation section of the data product. 

Following the August 2026 release, the legacy MES CSV file has been discontinued. MES data are now disseminated through the .Stat Data Explorer in accordance with the SDMX standard.
