Ooh, I just reread that, and realized I did miss that detail. Sorry
@dgatwood for missing that you said $2450 per stall. It was odd to divide the total power by 4 to calculate the power per stall and then apply the power factor (by what it's not based on) and then state the demand charge per stall, rather than multiplying it back up by 4 again to what the actual demand charge total for the site would be for the month. I guess the calculation does work out the same either way, but it lost me.
I've seen it a lot on this forum where people try to figure demand charges by calculating weighted averages per stall based on usage to come up with an average power draw level for the month and then multiply that by the demand charge. I thought that's what I read there the first time.
