Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what energy security assessment has been made of electricity supplied to the UK via international interconnectors.

The Capacity Market is our main tool for ensuring security of electricity supply and has already successfully secured the electricity capacity GB consumers need out to 2028/29. Interconnectors are part of the capacity mix that it secures. Like all technologies that participate in the Capacity Market, they are de-rated to reflect their expected contribution to security of electricity supply under periods of system stress. In the case of interconnectors, de-rating is based on consideration of expected flows and technical availability.
