DR - Inland Baseline Region

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.

The hour of day does not change what you pay here — the month does. Running the same house through the full year, July costs about $549 and February about $294. That $255 swing is part rate and part weather, and it is the reason a budget built on your spring bill will break in July.

There is a usage cliff to watch. The first 13.52 kWh you use each day are billed at 41.1¢; past that line the rate steps up to 51.8¢ — 26% more for every unit after. The last kilowatt-hour of a heavy month is the expensive one, which is why cutting a little off a big month saves more than cutting the same amount off a small one.

Before a single kilowatt-hour moves, this plan charges $290 a year in fixed fees. On the apartment above that is 13% of the whole bill; on the house with a car charging in it, 4%. 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.

Everything below stays inside Inland Baseline Region. Your zone is set by where you live, not by anything you can pick, so a cheaper plan in a different zone is not an option you have.

Measured against the other residential plans this utility files, a family home lands 9th cheapest of 10. The cheapest option, TOU-DR Inland Baseline Region, would run about $505 a year less.
