How many MWH does that battery array store? MW is a useless number for energy storage. HN should know better.
Edit:

So, at the 690GW (which is unrealistic) nameplate capacity of the solar field, they are installing roughly 120 minutes worth of energy storage to back it. This is actually a better number than most projects I've seen, but still utterly inadequate and representative of the typical project.
- oezi 2y agoBattery arrays aren't primarily rated for their storage capacity but for their ability to provide/consume power. At the moment the goal of battery storage additions to solar plants is to soften their peak power production and broaden the time they provide power to extend to the morning and dinner time. 690 MW.
- phil21 2y agoRight. So a useless number when it comes to energy storage discussions. It simply extends the duck curve an hour or three before you need use someone else’s power. Thanks for the correction on GW vs MW. Not a great typo.
