    We have this in CA. I have Tesla batteries and they promote wanting me to enroll my batteries into a larger grid so their capacity can be used during higher load events.

    I thought it was a novel idea when I heard about it.

      Tesla Electric customers report making as much as $150 a day: <a href="https:&#x2F;&#x2F;electrek.co&#x2F;2023&#x2F;07&#x2F;05&#x2F;tesla-electric-customers-report-making-150-day&#x2F;" rel="nofollow">https:&#x2F;&#x2F;electrek.co&#x2F;2023&#x2F;07&#x2F;05&#x2F;tesla-electric-customers-repo...

        there is something really wrong with the economics of this.

        it shouldnt be celebrated.

          It seems like an unreservedly good thing if people with home batteries can help prevent brownouts and reduce prices for everyone else. Also, I believe the $150&#x2F;day figure was during a rare heatwave event when prices had surged to 100x their typical value ($5&#x2F;kWh). It’s like any other investment where you outlay cash upfront and hope to make it back over time, whether via reduced costs for your own electricity usage or selling it back to the grid when doing so is profitable.
