Looks like I'll be driving around my S for free... go Texas!
Save With Free Nights Plan | TXU Energy
:biggrin:
Nothing is ever really free.
PGE has a relatively new (I think) Time of Use - three tier alternative, and while it saves you a lot of money at night, it costs you a lot more during the day.
Standard flat rate:
6.778 cents first 1000kWh - 7.500 after that
OR
Time Of Use:
On-peak 13.266 cents / kWh
Mid-peak 7.500
Off-peak 4.422
Then add (for either plan above) Distribution charge of 3.116, transmission service of 0.235
Along with $9.00 basic charge.
I'm noticing just now that PGE looks to be forcing EV owners to switch to the TOU plan - "enrollment is necessary" it states. I work from home, so this would cost me big, lest I start a night shift.
I suspect TXU is doing something similar.
It's a bit hard to compare the rates, since the basis and time periods don't match up. Here's one attempt - I'm sure with time we can work up better ways to compare.
Both plans retain the 3 rates: Peak, Part-Peak, and Off-Peak. The current E9 plans have tiered pricing, which means you start at one rate and it increases as your usage that month increases. For me and my one car we often went into tier 5. The new "Schedule EV" plan doesn't vary by usage, but does vary by season. Without getting into the specific tier pricing, here the pricing per kWh.
Summer:
Type Current E9A Summer New Schedule EV Summer Peak 30-54 cents 36 cents Part-Peak 10-34 cents 20 cents Off-Peak 5-20 cents 10 cents
Type Current E9A Summer M-F New Schedule EV Summer M-F Current E9A Summer SS-Holidays New Schedule EV Summer SS-Holidays Peak 2pm-9pm 2pm-9pm No Peak 3pm-7pm Part-Peak 7am-2pm & 9pm-midnight 7am-2pm & 9pm-11pm 5pm-9pm No Part Peak Off-Peak mid-7am 11pm-7am 9pm-5pm 7pm-3pm
Winter:
Type Current E9A Winter New Schedule EV Winter Peak No Peak in Winter 27 cents Part-Peak 10-34 cents 16 cents Off-Peak 5-20 cents 10 cents
Type Current E9A Winter M-F New Schedule EV Winter M-F Current E9A Winter SS-Holidays New Schedule EV Winter SS-Holidays Peak No Peak 2pm-9pm No Peak 3pm-7pm Part-Peak 7am-midnight 7am-2pm & 9pm-11pm 5pm-9pm No Part Peak Off-Peak mid-7am 11pm-7am 9pm-5pm 7pm-3pm
So, note that under the new plan you can start charging at 11pm instead of midnight. If you need more time to charge, then the new rate gives you an extra hour. But note that the new plan bumps you into Peak rates 3pm-7pm on weekends, where the existing plan only bumped you to Part-Peak 5pm-9pm on weekends. That could hurt if you're running air conditioning on the weekends (when you're home).
In general, people selling solar power back to PGE or people who don't go above tier 2 are better off with the existing plan. People who don't have solar and who regularly go into tier 5 might be better under the new plan. I don't know where the math works out for people in tiers 3 and 4.
I hope I got the numbers right. Let me know if I've made any mistakes and I'll correct them. The E9A numbers are from the latest PGE document for July 2012.
Based on bmek's profile (Monte Sereno, CA), PGE refers to our Pacific Gas & Electric in California not your Portland General Electric in Oregon. We're not in the northwest and not as close as you think (it's a big and tall state), this is the middle of California (SF Bay Area), though it's usually called Northern California just to differentiate from Southern Cal. And no, we don't have the cheap electric rates you have in Oregon and Washington. We have a large population (lots of consumption) with some hydro and nuclear but lots of natural gas plants, but we still import a lot of electricity - some from the Pacific Northwest.What up with PGE?!?! This is where electricity is made, right here in the Northwest, with all the hydro and wind farms we have along the Columbia and other rivers. We should have some of the cheapest power anywhere, but with rates like ours that I'm seeing you guys post... I now want to move to Texas. Who knew?!
California's massive electricity in-state generation system generates more than 200,000 gigawatt-hours each year and is transported over the state's 32,000 miles of transmission lines. In 2011, California produced 70% of the electricity it uses; the rest was imported from the Pacific Northwest (10%) and the U.S. Southwest (20%). Natural gas is the main source for electricity generation at 45% of the total in-state electric generation system power.

Here's a quote:
I used 2591KWh last month, but the average temp was 'only' 95f, this month will be worse. Best guess based on winter bills is that my run-rate, without AC, is about 1200Kwh per month, and I think I can move the majority of that to overnight, plus the car charging, of course.
The other upside is that I don't have to run aorund turning off lights that the rest of the household leave on, at least between 10pm-6
At first I thought the 2,591 KWh for a month was a typo! My total consumption last month was about 500 KWh.:smile: I guess there is some benefit to living in So Cal and near the coast!:biggrin:
We can all drive for free. I am. Solar panels are in and just finishing third year. And Southern California Edison has owes ME money for each of these three years! Driving on Sunshine (with minor capital investment at first :wink
Right on Timothy! If you don't mind me asking, what is your payback period for the investment? How many KW did you have installed?
Payback for me is about 10 years. I have an 8.4 kW system. I save about $2 grand a year on gasoline costs. But with the Tesla costing over $100 K that's a lot of years to break even! But it is great fun to look down your nose at one's liberal friends who don't have solar panels or an electric car!
BTW although government rebates for solar installations have decreased, the cost of the solar panels has plumetted, so the total out of pocket cost and payback times for solar installations is much better now than when I put mine in 3 years ago.

Comments welcomed of course.
