A system where you are incentivized to give up for the rest of the month if you were to high once doesn’t make sense. I am skeptical that the description was accurate.

It’s a peak demand charge. They look at the highest usage hour from 4-7pm every weekday. The highest number adds a charge billed at $19/kw demand.

It doesn't really incentivize that, but it doesn't punish it either

You would have to be really sure there wasn't going to be a higher peak later in the month

If the demand charge is always from 4-7PM and you have at least three hours worth of batteries at your own peak usage then your usage during that period can always be zero, because you have the other 21 hours in the day to charge them back up for tomorrow.
