19 Residential Service Time of Use Pilot Single Phase

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 is a time-of-use plan, which means the clock decides your bill as much as the meter does. At the worst hour you pay 16.1¢ a kWh; at the best hour, 9.9¢ — 1.6× apart for identical electricity.

That gap is worth real money only if you can move load into it. Every kilowatt-hour a day you shift from 7am to midnight is about $23 a year. A dishwasher run is roughly 1.5 kWh; an EV commute charge is 8 to 12. If your day is fixed — you are home in the evening and the air conditioner runs when it runs — a plan like this costs you more, not less.

Before a single kilowatt-hour moves, this plan charges $291 a year in fixed fees. On the apartment above that is 32% of the whole bill; on the house with a car charging in it, 16%. 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 $161 in July and $100 in February — a $61 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.

Everything below stays inside Wyoming. 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 2nd cheapest of 2. The cheapest option, 2 Residential Service Single Phase, would run about $42 a year less.
