kWh prices world-wide

I live in Georgia, USA and we have summer (June - Sept) rates and regular rates. Georgia Power (Southern Company) is my power provider. They have some of the nastiest Coal plants in the country. You can sign up for flat billing, time-of-use billing, or EV time-of-use billing. We get charged different rates depending on how much we use in a month. My power bill is almost always lower than my internet/tv bill.

Flat Rate Winter:
First 650 kWh: 5.0633¢ per kWh
Next 350 kWh: 4.3443¢ per kWh
Over 1000 kWh: 4.2647¢ per kWh

Flat Rate Summer:
First 650 kWh: 5.0633¢ per kWh
Next 350 kWh: 8.4166¢ per kWh
Over 1000 kWh: 8.6701¢ per kWh

Regular ToU Rate All Year:
'On Peak' (2PM - 7PM Weekdays Summer) - 19.2948¢ per kWh
'Off Peak' ( not 'On Peak') - 4.3626¢ per kWh

EV ToU Rate All Year:
'On Peak' (2PM - 7PM Weekdays Summer) - 19.2948¢ per kWh
'Off Peak' (7AM - 11PM and not 'On Peak') - 5.8295¢ per kWh
'Super Off Peak' (11PM to 7AM) - 1.2500¢ per kWh


I also pay 6% sales tax, ~6% environmental fee, ~3% Nuclear Construction Fee (only New nuclear reactor in USA in a long time is GA Power), and 85¢ county fee.

I am thinking about the ToU rates. But my Fiancee works from home a lot. Maybe she can go to the office during the summer. And my poor doggies need a solution for them too.

EDIT: I am on the flat rate program. I think it may be the cheapest option.

Here, it costs about 0.3 Norwegian kroner per kWh in electricity and 0.5 kroner per kWh in transmission cost. That's a total of around $0.14/kWh or €0.11/kWh.

There is no off-peak pricing, as we have enough hydropower that regulation of the power grid isn't an issue.

The cost per km for a Model X will be around $0.035 or €0.028. My Honda CR-V costs around $0.25/km or €0.19/kWh with gas prices here. My CR-V isn't exactly efficient, but even if I drove an efficient car, the Model X would still cost around 70% less per km.

In rural CO, $.1197 flat rate. Time of Use rate is $.13 from 7am to 11pm and $.01 from 11pm tp 7am. Naturally, I will be on the TOU plan and charge at a penny per KwH.

Do you use the range Tesla gives for the battery pack? Since I don't think you'll be able to get 480km out of the 85kWh pack.

That's why I use 320km for a real-world range of the 85kWh pack.

I used 250 Wh/km (340 km range), which is fairly pessimistic. How much range you get depends on how you drive. Here, the speed limits of most roads are a maximum of 80 kmph/ 50 mph, which is less than the reference 55 mph. If you drive at 120kmph/75 mph, a range of 320 km would be optimistic.

In Quebec, Canada, we only have one rate for residential (AFAIK).
Fixed charge : $0.4064/day
First 30 kWh per day $0.0539/kWh/day
Remaining kWh per day : $0.0751/kWh/day
add on federal tax (GST): 5.0%
add on provincial tax on the subtotal (QST): 9.5%


Using widohd's 90% efficiency of charging I estimated an average daily cost of approx $1.25/day to charge for my driving habits. This is of course assuming that my cost for the car is above the normal usage so doesn't benefit from the cheaper price for the first 30 kWh/day.


They (Hydro Quebec) are in the beginning stages of deploying smart meters but they are only talking about the automatic meter readings and outage detection so i wouldn't consider it being classified as a smart grid implementation just yet.

And transmission costs vary widely depending on where you live. I pay only 0.36NOK/kWH for transmission, thus about €0.10/kWh total including all taxes and VAT.

But the price can quickly change as I pay spot-market prices. Tomorrow power might be even cheaper, or prices could double. I get billed a one month spot price average.

See Below for California'a very high rates!

Hong Kong (Kowloon):

ä½￾宅用電價目


Total Bimonthly* Consumption Rate (Cents/Unit)
Each of the first 400 units: HK$0.778
Each of the next 600 units: HK$0.893
Each of the next 800 units: HK$1.034
Each of the next 800 units: HK$1.210
Each unit over 2,600 units: HK$1.295

The fuel clause charge is HK$0.178 per unit.
The rebate is HK$033 per unit.

A unit it 1kWh.

Worst case, around HK$1.44 per kWh (~US$0.1846/kWh).

No real off peak benefit. Rumors of a solar feed-back to the grid system coming, but nothing substantial.

Here in Boston, the optional residential TOU rate currently is priced at fairly obscene levels, which is why I plan to charge mostly at the office, where the parking garage pays the power bill:

Tokyo, Japan (Tokyo Electric Power "denki-jyouzu" plan, 1US$ = 81.6JPY)

I pay

6.7 cents/kWh day or night. There is less than 2 cent surcharge for every kWh over 600 kWh

Benji: 40.9 cents/kWh in the summer? Wow.

I like to think, though I have no proof, that after 10 years of having solar panels pay for all of my electric use AND power an EV for 60K miles, that my PV system has paid for itself, so I seem to go around with the idea that my power is now free. Actually, since PGE have agreed, they now pay me for excess generation, and I like that, too.

If you start now, in a few years you can begin to think that maybe you, too, have gotten to the balance point and no longer have to pay for electricity. Well, at least for 20 more years or so.

No, I don't feel smug. Just that it seemed to make sense then, and the longer I go, the more sense it makes YMMV.

See Lloyd's post on CA rates. With a pool and fishtanks (gotta love those 24x7 power draws - I've made those tanks as efficient as I can, but getting rid of them has a near-zero WAF), we were creeping into tier 5. We estimate a ~7.3yr payoff on the solar. PG&E rates are definitely not cheap, but since the solar keeps us down at tier 1, if I did have to charge at home (I think it's been 6 months?) it'd be appropriately cheap.

(Really, if you're a software company in the Bay Area, and you're not providing free charging at work, what's wrong with you?!?)

Actually, Quebec has an other option which is called the domestic dual-energy rate. As you can see from above, electricity is pretty cheap in Quebec thus many people heat their homes using electricity only. When temperatures plunge (and it gets pretty cold in Quebec) electricity demand climbs. In order to lower the demand during these peak periods they offer the dual-energy rate. Basically, your primary heat source is electricity and you have a secondary heat source (natural-gas, propane or oil) which kicks in when temperatures drop below -12C (or -15C depending on you zone). Fixed charge is the same.

cost when temperature is equal or above -12C : $0.043
cost when temperature is below -12C: $0.1832

By the way, almost 98% of our electricity comes from hydro (hence the name Hydro-Quebec) and about 2% comes from nuclear (http://www.hydroquebec.com/sustainable-development/themes/index.html). I think it's pretty safe to say that an EV charged on the Quebec power grid truly is zero emissions. Now if I could only afford a Tesla. Maybe the Blustar or a used Model S. I did convince one of my friends to buy a Model S. I could buy it off him in five years.

PGE rates are offensive ... and my new-ish solar system (this year) has eliminated the occasional foray into Tier 2/3/4 prices. Most days now I'm zero'd out. But a year ago, I had some outrageous bills. These are the current (winter) rates for Tiers 1-4.

You shouldn't charge your Model S with the 85kWh pack in the middle of a hot summer day, that will cost you a lot.

No kidding. My Roadster starts charging at 1am. I've shifted a lot of usage to off-peak hours - pool pump, car charging, delayed washer, delayed dishwasher, etc. The good news is that the excess energy I produce in the daytime is credited at the higher rate and the majority of what I use is billed at the lowest rate.

In Manitoba our residential cost is $0.0662 per kWh, plus 1.4% provincial tax and 5% federal GST.

There is no real net metering for my photovoltaic array; they give me the base rate for anything that feeds back into the grid. So, I will be charging my Tesla at high noon when possible.
