Interesting to see the different power usage and electricity rates for a different part of the globe. Here in the Houston, TX area we used 848 kWh in a 30 day winter period for a mid-sized home, which is as much as the article states the household used in a 95 day period. During the summer, when my old AC unit is running like crazy, we'll use ~1800 kWh, and our rate is an average of $0.102 USD, which is around 60% of the top rate from the article.
A Powerwall unit still wouldn't make sense for us, but this is rev 1, and so in a couple of generations we could be looking at something that actually could be impactful.
