Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether her Department has assessed the extent to which regional electricity carbon intensity varies from the national average; and what estimate she has made of the average carbon intensity of electricity in the South West during overnight off-peak periods.

The National Energy System Operator publishes regional carbon intensity forecasts, including for South West England, through its Open Data Portal.

Regional Carbon Intensity Forecast | National Energy System Operator

Regional carbon intensity can vary due to a range of factors, including the location of electricity generation and patterns of demand. However, Great Britain operates as a single, interconnected electricity system, with electricity generated in one area able to meet demand elsewhere. This supports security of supply and affordability by enabling electricity to flow between regions and making efficient use of generation.

Regional carbon intensity estimates therefore do not necessarily reflect the carbon intensity of electricity consumed in a particular region.
