Historic generation mix and carbon intensity
The carbon intensity of electricity measures how much carbon dioxide emissions are produced per kilowatt hour.
This dataset contains data from 1 January 2009. It has seasonal decomposition applied to correct missing or irregular data points. The data is subject to change due to a data cleansing process taking place to provide the most accurate figures.
Batteries (NET discharge) are currently included in the OTHER category. Transmission-connected solar farms are currently included in the OTHER category. Pumped Storage units (NET) are represented in the STORAGE category. All Net-Negative values are curtailed at zero.
Updates will be released later in 2026, to highlight BESS (Battery Energy Storage System) and Transmission Solar values.
