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.

Plus a fixed charge of $15 per month.

Should you be on Rg-1 Residential Service Single Phase?

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 $178 and February about $97. That $82 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 $180 a year in fixed fees. On the apartment above that is 21% of the whole bill; on the house with a car charging in it, 9%. 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.
