UK power system operator National Grid plans to expand its Demand Flexibility Service (DFS) – used to control demand and supply of power - to be used over the entire year instead of just winter, as excess generation during the 2024-25 winter is anticipated to be higher on the year.

• The UK’s de-rated margin – excess output that National Grid can use during peak demand periods – is expected at 5.6GW for winter 2024-25 compared to 4.4GW last winter, according to the system operator.
  
  
• The new DFS scheme will be discussed with the industry over the summer before a final design is submitted to Ofgem for approval ahead ahead of a planned winter go live, National Grid added.
