The first article is an example of what I am talking about, I linked to the second one to make it clear they don’t currently release battery power at night.
Anyway, I think it’s reasonable to think in terms of “50 MW of PV solar and 30 MW * 4h of battery storage” + a wind farm because they normally charge batteries from solar via DC to avoid DC>AC>DC losses. But it might be a true hybrid system.
It represents less than 10% of the max power output of the plant (380 MW)
When I read "The battery section will provide four hours of storage capacity at full discharge" I understand that it will provide 4h x 30MW = 120 MWh of energy. Do you understand it as 4h x 380 MW = 1520 MWh of energy ?
[EDIT] From other source [1] it seems my interpretation is the correct one: "The onsite battery storage facility will be capable of providing 30MW of continuous power for four hours."
That completely changes the narrative: the total energy the battery storage can deliver by itself is less than what the solar + wind provides at full power in half an hour. Also, this amount of energy will be delivered at a peak power of less than 10% than the peak power of Solar + Wind
