"Grid Stabilisation Park"

Ok so what tech is in these "agricultural barns and storage units"?!

I would take

(They have identified Norfolk as an area which requires grid stabilisation.
This new Necton Greener Grid Park will provide that in a clean, green way, helping to make fossil fuels a thing of the past, Statkraft said.)

The stability is provided by large machines, called synchronous compensators.
These are designed to deliver the inertia needed to stabilise the grid and eliminate the need to run fossil-fired power plants for this purpose

to mean big rotating motor/flywheel/generator things. (I don't think they would call a battery and an inverter a machine.)

Some of these: https://en.wikipedia.org/wiki/Synchronous_condenser

Big flywheels to provide synchronous compensation so the grid can operate with zero gas, thus allowing more renewables to operate before they are curtailed.

From the website of the company installing them.

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.

ok cool - giant flywheels - sounds like a good old Victorian solution!

What's the difference between one of these and those great big spining wind turbine things?

Being serious here, not trolling: I don't get why wind turbines don't work for this?

[SimonSays]

As I understand it, offshore turbines are DC back to shore. I'd assume that the DC to AC conversion can only work to raise frequency - if the grid frequency is already high then additional load need to be put on it to bring it back down, and of course a wind turbine is never a load.

OK, that makes sense, cheers
