Note that elif said "overnight" rate. I'm pretty sure they're on the EV rate plan from GA Power[1]. You only get that rate at night, and you pay a pretty punitive $0.21/kwh for any peak usage. As they mentioned, that's a pretty solid number for the marginal rate you'll pay for an extra kwh, but there are a number of base fees tacked on to that. I'm not on the EV plan, but my average out the door winter final rate is about $0.13/kwh and my summer rate ends up being more like $0.17/kwh.

Pff, your punitive 21¢/kWh is cheaper than our overnight 25¢/kWh or so in the Bay Area :P

Is night time energy still cheaper than day time? I thought that with the rise of cheap solar, day time energy would have been cheaper by now.

That also incentivizes home battery systems. Charge it up overnight and then use the battery power during peak times. It's a good deal for the power company if you do that too because it reduces amount of swing in the grid.

I modeled buying a few Tesla Powerwalls to do time of use shifting, and it didn't make any sense from an investment standpoint. It's a great incentive if you were buying the battery backup anyway, but not as an investment.

Yup during peak hours I'm usually pumping 3-5 kw to the grid. It's a win-win.

[mcv]

It also incentivises solar, which provides super cheap energy during the day.

It's worth noting that the "punitive" peak is only 5 hours, does not include weekends, and is only for 4 months out of the year.

And since it is during peak solar hours, I've never had to pay that rate once.

Oh, that makes more sense.

Still great for charging your EV overnight
