At $2/kWh you’re making as much as $16-$20 per cycle so it is almost certainly worth it to the battery owner to use your battery for this vs. load shifting, etc

$2/kWh is insane though. My power rate is $0.12/kWh. $2/kWh is still 6x California’s most expensive power.

  > $2/kWh is still 6x California’s most expensive power. You only need that power ("operating reserve") for extremely short times in a day, the rest of the time the power plant stays idle. Mostly these are hydro pump dams or gas peakers (as they can start in well under 60 seconds), batteries are a relatively new thing - and all three of them are pretty expensive to build, so it is obvious that their power generation comes at a high enough price that the plants still stay profitable.

  Yesterday the peak price for electricity in Europe was 4€/kWh (that was in Estonia, was one hour period, due to some production issues at multiple power plants).[1] [1] https://news.err.ee/1608686533/estonia-s-electricity-price-to-peak-at-record-4-000-per-mwh-on-wednesday https://news.err.ee/1608686533/estonia-s-electricity-price-t...

    And FWIW: I pay 0.42029€/kWh to my provider in the Netherlands while getting back 0.115€/kWh back for every kWh delivered back to the grid (after I generated and used most of it in my home) Used to be 0.23ct or something. I don't want to talk about or look at the prices for a cubic meter of gas...

      Here in Estonia the spot market pricing works the same both ways. So I set my system to feed at 7kW during the hour and made about 28EUR for helping the grid. That is twice the $2/kWh this Tesla peak power provides but it's literally the only time price has gone this high.

  You're confusing peak pricing with average pricing. Peak price is about 50-250x as much as average price.
