The lowest price on the PG&E tiered rate plan E1 (implied by the words "If you use very little ...") is $0.42/kWh. Even the most variable rate EV2A plan has an off-peak price of $0.35/kWh. I don't see any way to get a price of $0.15 kWh.
Typical PG&E rates are US$0.12/kWh, which includes not only buying the energy (at prices ranging from -$0.05 to $1.50 or more, depending on supply and demand) but also maintaining and constructing the transmission and distribution systems, as well as incidental additional costs like black start capacity, loan interest, and investor profit.
Where does the pricing data come from? The page for my own utility, PG&E, says the average residential rate is around $0.12, but no plan exists anywhere close to that. Residential plans start at $0.32.
average residential electricity rate is 15.34 cents per kWh
This didn't seem right, as I pay more than double that here in San Francisco. (I calculated $0.35/kWh by dividing the total I paid for electricity generation and delivery, and dividing it by the number of kWh consumed.)
The linked page cites data from over a decade ago (2012).
I'm on SCE in California and I pay about $0.73 per day in "Basic Charges" (about $23/mo) if I use zero power. There are also grid-related charges (including a wildfire fund charge) that are usage-based on the order of $0.03/kWh. For my usage (about 1MWh per month) that means half the grid charges are flat and half are from usage.
For comparison, my TOU energy rates range from $0.06 to $0.25 per kWh depending on the season and time of day.
My utility charges residential customers $0.11 per kW-h
Large users pay $0.06 per kW-h and then a demand charge of $10 per kW based on their max draw for the month. So if you do a bit to smooth out demand, the resulting cost isn't going to be wildly different than residential.
Tier 1 rate for me is currently about $0.35/kwh and tier 2 about $0.41/kwh from PG&E. They don't directly tell you the transmission cost, but about $0.145/kwh comes from generation.
For my 1 br apartment living alone the total bill has been about $100-$150 but can jump to up to $250 during summer months. Sounds like this will almost double my costs for most of the year.
PG&E rates are based on some fictitious "average" household, which uses electricity and gas.
Then you pay more if you use more than this household did. ($0.22/$0.27/$0.48 per kwh, and $1.28/$1.88 per therm gas)
The thing is, if your household only has electricity for heating which is not as cost effective as gas, you may end up in the $0.48/kwh tier for electicity.
If you use very little on the residential schedule I think it can drop pretty low, probably around $0.15/kWh.
