100% RE electricity this morning.

I think that would be called a synchronous condenser.

Flywheels and synchronous compensators are not the same.

High-Inertia Solutions
Lister Drive Greener Grid Park is ABB’s first project to feature a high-inertia compensator configuration. This approach couples a 67 MVAr compensator with a 40-ton flywheel.

Combining a mid-size synchronous compensator with a flywheel has the important advantage of multiplying the available inertia by several times. At the same time, the losses may be lower compared to installing the whole inertia as a synchronous compensator. It is also a cost-effective way of using two mid-sized compensators together with the benefits of a high level of redundancy, increased inertia and greater controllability.

Together, the two units at the Lister Drive Greener Grid Park in Liverpool provide a total of more than 900 MW-seconds inertia. That means Lister Drive will provide about 1% of the UK’s projected minimum total inertia requirement for 2025. The compensators were commissioned in March 2023.

Well ..... you live and learn.

Here - 40 ton flywheels to provide synchronous compensation

Dan, you need to check your synchronous compensation as you seem to be a bit out of phase.
