Hi william
Is California now doing demand charges?
And is it instantaneous or 15 minute average?

Friends:
I am pondering a plan to prevent usage spikes. It would involve installing a battery inverter that has true generator support. Connect the utility to the generator input on the inverter and program the generator amps to just below the threshold that incurs peak demand charges. If the load exceeds that amount occasionally the inverter supplies the difference. The battery is sized to sustain the shortfall for the expected duration.
The potential to save $300 a month provides a budget for the project.
Peter,
Right, that is about it. The fee is a monthly fee. It will take a year
of keeping the spike below that before the fee will be dropped from the
bill.
Thanks,
