Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether the National Energy System Operator's Demand Flexibility Service is designed to reduce carbon emissions in all regions of Great Britain; and what assessment he has made of the potential impact of that service on emissions in the South West.

The National Energy System Operator’s (NESO) Demand Flexibility Service (DFS) is designed to support efficient balancing of the electricity system by rewarding consumers who choose to flex their electricity demand. The DFS can contribute to reducing emissions where demand is shifted away from periods of likely higher-carbon generation, with scale varying depending on time, location and network conditions. NESO has continued to evolve the DFS, introducing demand turn-up and regional procurement, and incorporating the Local Constraints Market. NESO has not undertaken an assessment of the emissions impact of DFS in the Southwest.
