Flywheel Generator Convertors (FGC) Repurposing Project

UKAEA is entering a multi-year decommissioning programme of the Joint European Torus (JET) experimental fusion machine at the end of 2023 under the JET Decommissioning and Repurposing Programme. One of the key existing systems that have historically provided additional power to the Fusion machine will no longer be required for their primary purpose and an opportunity exists to repurpose the equipment for alternative use. A preliminary feasibility study has identified that the Flywheel Generator Convertors (FGCs) could be repurposed to provide inertia as part of the National Grid Stability Services (ESO), it is expected that the flywheels could provide more than 5 GW.s of inertia. This PIN is to establish third party interest in this opportunity, said parties recognising the need for investment to upgrade & operate the JET flywheels for grid load balancing.
