The question

To ask the Secretary of State for Energy Security and Net Zero, whether he has considered mandating market payments from intermittent renewable generators for costs associated with system inertia provision.

Answered by Michael Shanks

The National Energy System Operator (NESO) continuously monitors the electricity system and ensures that there is sufficient inertia. In the transition to clean power, we are deploying the technologies needed for this. NESO is procuring technologies such as synchronous condensers and flywheels and use sub-second response services to manage frequency changes and maintain system stability.
