ES (Residential Service Energy Star, All-Electric)

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 $142 and February about $84. That $59 swing is part rate and part weather, and it is the reason a budget built on your spring bill will break in July.

Before a single kilowatt-hour moves, this plan charges $168 a year in fixed fees. On the apartment above that is 23% of the whole bill; on the house with a car charging in it, 10%. 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.

Measured against the other residential plans this utility files, a family home lands 3rd cheapest of 22. The cheapest option, RETC (Residential Service All-Electric Time of Use with Critical Peak Pricing)), would run about $48 a year less.

Against Residential Service (RES-55) Single Phase, which looks like the plan you land on by default, this one comes out $301 less per year (19%). We infer the default from the tariff structure rather than a flag in the data, so confirm it against your own bill before you switch.
