Isn't 129MWh of capacity a bit low for 100MW of peak discharge? That would provide 77 minutes of power at peak discharge. Does anyone have any insight into the rationale for this capacity?
- davedx 9y agoFrom what I've seen this is quite common with batteries -- the rated power output number is usually in the same ballpark as the storage number. I'm no expert, but I would guess it's because most of the time the wind will be blowing somewhat, so you will rarely need peak discharge. Most of the time the batteries will be providing load smoothing and frequency regulation.
