TLDR: The grid operator had inadequate spinning mass on the grid to keep it stable.

Vacuum can be maintained by a small amount supplying steam to the the turbine and condensing it in the condenser

My point:
The installation of a large battery bank and suitable inverter.
Perfect. Part of carbon emissions 100% eliminated.
But;
High capital Expense and long lead time.

The installation of a synchronous condenser..
Perfect. Part of carbon emissions 100% eliminated.
But;
High capital Expense and long lead time.

Disconnect turbine and install pony motor and controls.
Perfect. Part of carbon emissions 100% eliminated.
But;
Lower capital Expense and shorter lead time.
or
Vacuum can be maintained by a small amount supplying steam to the the turbine and condensing it in the condenser
Excellent. Part of carbon emissions almost 100% eliminated.
Mostly done by changing control settings.
Capital cost, nill. Lead time? Will next week be okay or do you want it later this week?
Perfection will always be the enemy of excellence.

Inertia and VAR control are both necessary components of regulation. if the tariff values them appropriately they will be available when needed.

Here they obviously were not valued appropriately. Will they be the next time they are needed?
