Isn't a power emergency exactly the time you want your battery to be full? Why would someone with batteries want to drain them for a pittance and just be another person without power?

most power emergencies are quite short, and are especially short if there is a sufficient demand response

Putting ~1-5% of your stored energy towards keeping the grid running and affordable means that you rarely have to use the other 95% and pay less overall.

Hardly a pittance, $2/kwhr is a crazy high rate.

  It's $20 for a 10kWh battery and you then don't have sufficient energy left when they shut it down anyways. Hardly seems worth it.

    If you read the release there's a Backup Reserve setting: > • If you prefer to reserve more energy for use during a grid outage, or if your area is more prone to outages, you can set a higher reserve percentage. So you could easily reserve 50% for yourself to run the fridge/lights or whatever and sell up to half.

Demand based outages are likely to be transient. We sized our batteries and solar (and fireplace) to get us through multi-week outages in winter (PG&E really sucks around here...) The AC drains the batteries overnight, so we wouldn't really need the charge between now and dawn anyway. Since we sized the batteries for winter emergencies, after selling all but reserve capacity, we'd still have enough left over to power the electronics and plumbing all night.

This program is mostly (entirely?) aimed at using your battery storage during peak demand times - not power outages. That's why they can pay so high, because they bill hundreds or thousands of times more than the normal rate to really high electric consumers during these peak peak times
