  • American House with an EV, all electric, and no solar, I use about 1200 kWh/mo (1.2 MWh/mo) on average. This could only carry me through about 3y. Even if I had access to good public infrastructure I think best I could do is 6y (again, all-electric home).

    But I digress. Lithium ion as purely load shifting is a pretty reasonable, I’d argue critical, solution for covering day/night loads, but starts to fall apart completely when it comes to seasonal (summer/winter) loads.

    But what makes this plant interesting is the addition of super capacitors. The combo battery/SC plant is less about day/night load shifting and more about providing stability to a shifting grid. As supply and demand grow increasingly decoupled, and we try and shift away from expensive peaker plants always on standby, systems like this can dramatically help smooth grid performance.

    ~90 MW of peaker capacity is small potatoes currently, but this is a big step towards a more reliable grid future.

















  • Of course some people go too far. I think a lot of folks on here grossly overestimate / overstate their threat model, but I think the discussions are good for the limited few who really do need to cover their asses.

    Me personally, I hate the idea of companies bidding for my attention without my consent, so I try and make it as hard as possible for them to get it. This just so happens to overlap nicely with the goals of the privacy community much of the time.
