Elon is great,
We surrender our will
As of this date.
Looks like Crimea needs to build more pylons
it could put a call out to any EV currently plugged in saying "I'll pay 6 cents per kWh for what's in your battery". If they don't get as much power as they need, they would put out another request at 7 cents. If you paid 4 cents the previous night, that's a good deal for everyone.
You'd be an idiot to accept that deal!
1) Your EV's battery doesn't charge/discharge at anywhere near 100% efficiency.
2) Batteries have a fixed number of charge/discharge cycles, so the energy you pull out is significantly more expensive than the electric rates. It may not be much cheaper than running a gasoline/electric generator in your back yard...
3) On a TIMEÂ-OFÂ-US rate schedule, you pay about SIX TIMES HIGHER for your daytime electrical usage. I just found Nevada Electric TOU summer rates of $0.06159 for off-peak, and $0.36554 for peak (all-day, really). So until they're paying you more than $0.40, you'd be far better off serving your own household's electric needs from your EV's battery, not selling it back to the grid. Of course nobody does that because of point #2 above.
4) If it was at all a profitable proposition, the power company would cut-out the customer, distribution losses, retail rates, etc., and build their own battery banks. That they don't should be a huge hint that the economics don't work.
5) As an added bonus, your car doesn't have its full range when you suddenly need it, and it will take an hour to top-off the charge.
6) If utilities would quick trying to heavily penalize residential PV customers, they would quickly get lots of Summer peak power.
Buy power to charge up on windy nights and sell on hot days. (In summer, anyway) Bulk wind power in Texas on the spot market has actually dropped below zero on a few occasions.
Except that's not a viable business model. It costs way the hell too much money to build a huge energy-storage facility, to not maximize day-in, day-out profits. In other words, you can't leave your battery-bank half-charged every day, waiting around for the occasional free electricity to take advantage of. In fact it's most profitable to build a facility that doesn't quite meet all the demand.
Also, wind power in Texas only goes negative by 1/3rd of the subsidized price (i.e. producers are earning positive money), so when the subsidizes get reduced or go away, so does the free electricity.
It still boggles my mind how we live in the Information Age and this data was not automatically uploaded and calculated.
If you should have learned anything about "the information Age", it's that life-critical systems should NOT be highly interconnected. If it's just a single 5-digit number that needs to go from point-A to point-B, plain-paper sneakernet is quite convenient and by far the safest and most reliable option.
I've got a bad feeling about this.
