On the contrary, I would expect to be paid higher rates for the energy I'm supplying to the grid than those I paid to charge it in the first place. Otherwise, what's the point? I'm not going to buy a kilowatt-hour high, then sell it low.
Only way these grid balancing schemes work is if the pricing is real-time, and I have an opportunity to supply marginal peak demand at rates that are higher than what I paid to charge (while still being lower than what peaker plants would cost)
- jlmorton 4y agoIt's worth pointing out that Tesla's Virtual Power Plant in California -- which is used primarily in emergency events -- compensates owners $2/kWh. [1] Obviously, that rate is not going to be sustainable for routine energy storage, but PG&E is already compensating EV owners a substantial amount for peak electricity needs.

However, this was coordinated with PGE to match the lack of production (in advance, which is its own miracle) and unlike a car, the battery doesn't change locations or need to be unplugged at random.
