That sounds similar, though not identical to my rate plan. 7.43 cents from 9pm to 7am, then 11.9 cents until 5pm, and then 32.8 cents from 5-9. Clearly they want people to just turn off everything they can at 5pm.
> just 6 kWh or so of batteries I could completely eliminate my peak power usage
Out of curiosity I took a wild ass guess at what it would take for me.
I usually use about 7 kWh between 5-9pm, so lets say ~$2K for an even 10 kWh of LFP. Probably at least that much more to get a suitably capable 240V inverter and smart transfer switch. My low quality napkin math says at least 20 MWh to break even. I probably wouldn't make that bet. It would take a long time to go net positive and any kind of equipment failure would instantly tank the ROI. And that's also ignoring the time value of money altogether.
If the batteries were free, it would be a somewhat better deal, but still not a slam dunk.
Yeah. A lot of it, for me, would be to ride out small power outages and blips. Taking money off my bill is the kind of secondary benefit I’d need to actually give it a shot.
