I looked at <br>
her APS bill - it was $120/month. They were seriously considering <br>
spending $25K to cut down on the peak demand charge. The most they would <br>
save was $20/month. That's an ROI that would never be achieved.<br>
<br>
I have solar. APS invited me to buy a battery and they would pay me <br>
$1250 if I let them manage it. The battery was quoted at $15K. Yeah, no. <br>
So let's say I use the battery to keep my 4pm-7pm APS draw minimized, <br>
what is my ROI? Looking at my past bills, my peak demand charge ranges <br>
from $5 to $121 per month. Let's average that out to $65/month. So $15K <br>
to save $65/month gives me an ROI of 230 months. It will be less due to <br>
APS price increases, but that's still 15-20 years out, and by then the <br>
battery would need to be replaced, nullifying any notion of an ROI.<br>
