Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, how much has been paid in in constraint payments each year since 2015.

National Grid ESO compares the cost of constraint payments and of building new network to ensure efficient investment decisions are made. National Grid ESO publishes constraint payments in its ‘Monthly Balancing Services Summary’ available at https://data.nationalgrideso.com/balancing/mbss.
