Doesn't seem to be any inspection for this at all....it just...happens.
The part about on-peak increasing sucks though...there is some stuff you just can't avoid during on peak, like AC in the summer. Tying this to the "new super low EV off peak rate" will just piss off more people and make them hate EV's even more than they might already.
In unrelated news, watching Dougie suddenly jizzing in his pants about clean energy and EV's blah blah blah after all the **** he did to damage all that when he got elected puts even more of a sour taste in my mouth for this dolt. The "here's a bunch of money back from your licence plates" vote buying scheme, plus the "we'll cut gas taxes after we get elected" vote buying scheme #2, even more of a bad taste.
I can't wait for him to be shown the door in a few weeks.
Anyhow, as for storage to take advantage of the super off peak rates to feed the house during on peak, well, I'd have to do some math on the ROI potential. Used Volt packs can be found for $2000-$3000 (not sure about others, but Volt packs are popular) and give you about 13kwh usable each. Looking at my stats for our central AC, I see we used somewhere in the vicinity of 25 to 30 kwh in the peak days in August, for example, so to power JUST the central air I'd need at least 2 Volt packs (and that could still run short on the worst hot days unless you push depletion a little more even, not good for pack longevity) plus all the inverters and such. So, realistically probably something like $8-$10K investment...just for AC.
At 15c/kwh at 30kwh per day, $4.50 per day potential savings. So assuming 120 air conditioning days over an average summer, $540 savings in a single summer.
Over the winter, we're powered by gas, and our actual consumption is much less. On Saturday March 26th for example, 1 day where I could see our usage was pretty low and neither car charged (so just "actual" usage, no cars involved) we used just around 30kwh for the entire day. So even if we took the house completely offline during the peak and mid peak rates, what, maybe 3/4 of that would be saved? So say 22kwh saved, $3.30/day. x30 days = basically $100/month in the winter.
So, ROI on a $10K off grid system would be surprisingly long.
If you can find some 10+kwh packs on the cheap, the math changes....but used EV packs are hot commodities right now so cheap ones don't really exist.
