National Data

The carbon intensity of electricity is a measure of how much CO2 emissions are produced per kilowatt hour of electricity consumed.

The ‘actual’ value (orange line) is the estimated carbon intensity from metered generation. The ‘forecast’ value (blue line) is our forecast. The carbon intensity of electricity is sensitive to small changes in carbon-intensive generation. Carbon intensity varies by hour, day, and season due to changes in electricity demand, low carbon generation (wind, solar, hydro, nuclear, biomass) and conventional generation.
