Peak Determination
How to add load without raising the charge that follows your peak.
What sets your peak, what it costs on your tariff, and what new load such as EV charging does to it.

What You Can Decide With It
With the two starts staggered the month’s peak is 227.5 kW and the charge is $349 lower. Tariff and figures are a specimen.
The Interval That Set the Charge
Each month's peak 15-minute interval, the loads that coincided to make it, and what it cost on your tariff.
Six 11.5 kW chargers on the Jul 15 curve. Solid line, charging from 07:00; dashed, charging from 22:00. Specimen figures.
What New Load Does to the Peak
The same peak day with the new load overlaid twice: charging as vehicles arrive, and charging managed away from the busy hours.
