I love this. I think of it as a 4-hour uninterruptible power supply for 20,000 homes. Not mentioned in the article but it’s also a way to “time shift” power consumption from other sources. Not unlike Tesla’s powerwall, which is primarily intended to make solar more practical, and yet also serves as a kind of UPS as well. Oh, and this came in cheaper, and earlier than expected. 🙂
