This dataset provides indicators on electricity generation by source of energy in large (TL2) and small (TL3) regions. Data definition and source The electricity generation mix is based on both official subnational statistics and on estimates (see the data sources). The estimates for areas with missing official data are based on the electricity generation mix at the national level (based on the issued from the International Energy Agency (IEA) database, the location of electricity generation assets using the Global Power Plant Database (GPPD, Global Energy Observatory et al., 2018) and the harmonised global dataset on wind and solar installations (Dunnett et al., 2020). Electricity generation is estimated by matching energy sources across datasets, calculating each power plant's share of national capacity, and distributing the official regional and national generation accordingly across the different subnational areas. The carbon intensity of electricity generation is defined as the amount of CO2 equivalent emissions produced per unit of electricity generated (gCO2eq/kWh). It is obtained by applying emission factors to the different energy sources. Definition of regions Regions are subnational units below national boundaries. OECD countries have two regional levels: large regions (territorial level 2 or TL2) and small regions (territorial level 3 or TL3).
