12 (Residential & Farm Large Demand General Service) Secondary

Estimates, not quotes. We run three made-up but realistic households through this tariff hour by hour for a full year — including the way air conditioning loads the afternoon and an EV loads the small hours. Your own bill depends on when you actually use electricity, which is exactly the thing a per-kWh number hides.

This plan bills a demand charge on top of the per-kWh rates: a fee tied to your single highest hour of the month. Two homes using the same total electricity can pay very different amounts if one of them runs the dryer, the oven, and the car charger at the same moment. We do not price demand charges yet, so treat every dollar figure on this page as a floor, not a total.

Before a single kilowatt-hour moves, this plan charges $5,236 a year in fixed fees. On the apartment above that is 90% of the whole bill; on the house with a car charging in it, 78%. Fixed charges are invisible in a cents-per-kWh comparison and they punish small users hardest — if you use very little electricity, the headline rate is the least important number on this page.

Expect the bill to move with the calendar. The same family home costs about $561 in July and $504 in February — a $57 spread driven by heating and cooling far more than by anything you chose. Budget against the July figure, not the average, and a summer bill stops being a surprise.
