EcoRenovator - View Single Post - DIY Interactive grid tie-in with battery back-up

This got me thinking of a concept that may have some validity; short term battery backup only for peak hours.

With the rapid introduction of smart meters, it is easy to adjust your consumption, but what about the family with two kids, all coming home and dinner needs to be prepared. But this is just at the time of peak power . . .

Perhaps a small backup of batteries to get you through this peak power period. Many of us realize the math of using batteries to compete for grid power is not cost appropriate. But this is at $0.10/kWhr.

The equation completely changes when power is at $0.50/kWhr (or more).

May have gone off topic, but this combination of interactive grid with battery backup may have a lot of financial utility.

Thoughts?
