This platform offers a global overview of electricity market structures across 230 economies from 1989 to 2024, highlighting how power markets have evolved over time.  

Through the tabs at the top of the page, users can navigate detailed information about wholesale and retail market structures, the presence of a national regulator, the degree of transmission unbundling, and the participation of private Independent Power Producers (IPPs). 

The interactive dashboard below presents a snapshot of power market structures—Vertically Integrated Utility (VIU), Single Buyer Model (SBM), or Wholesale–Retail Competition (WRC)—through a global map. To the right, summary bar charts track key governance indicators, including the number of countries that have moved away from vertical integration, implemented unbundling, established regulators, or allowed private IPP operations. Additional resources at the bottom of the page include analysis with the data, the data source, and a link to download the dataset. 

To explore the data, use the filters above the map. Select a year to view the market structure characteristics at that point in time or choose a specific economy to access detailed information on its current setup. You can also hover over an economy on the map to view key details about its market structure and governance features.
