My Current Monthly Electric Bill Is Amazing

Since my MS delivery 6 weeks ago, I couldn't wait to see my full monthly electric bill to compare my last year's. I am happy to report that I only pay 80 cents more for 29 days of driving the MS. Although this is only one month bill along with some routine changes, it may not be a fair comparison but you've got the idea.

Details:

* I had Progress Energy (North Carolina) installed the Time-Of-Use meter while the off peak hours are 9pm starts on weekdays, all day on weekends and holidays.
* I charged my MS every night after 9pm and weekends.
* We started doing laundry/dryer and dishes during off peak hours

My electric bills comparison:
3/26/13 (29 days) KW Usage: 1229KW, $.0658/KW, Total $80.87
3/26/12 (29 days) KW Usage: 678KW, $.1181/KW, Total $80.07

Now if I compare driving my Acura versus MS, it is even more dramatic, I basically save almost all of my fuel cost. My average fuel cost last year was around $54/week or $2808/year. WOW

Double the kWh at half the price per.

nice :)

Ours was $44.00 for approximately 2,000 miles. Happy is an understatement especially considering how large the car is.

2.2¢/mi? Yep, that would be happy-making, for sure.

Heh, did you ever check out the projections at LPPhysics.com ? If their product and projections come through, the cost could drop by another order of magnitude or so. That would be 4-5 mi./¢ ! Your 2,000 mi. would have cost you less than a fiver. About 1% of gas costs, at most.

Smart!! More dollars in your pocket ..., kudos!!

A lot of people think that EVs run up the electricity bill. I found that by switching a few lights from incandescent to CFC and switching to TOU rates, I basically offset my entire electricity bill.

CA is trying hard to make electricity as expensive as gasoline. It will likely succeed.

Brian - CA heavily promotes solar. For me, now 6 yrs in, my electricity and my MS charging are soon to be so low as to be nominally free (minus depreciating the inverter which will need to be replaced every 8-10yrs). So guess it's how you look at it or what you take advantage of.

I am in Northern California. Owned model s over two months. Driving 1200 miles per month. Local utility is PG&E. My electric bill went up 30$ per month.

The key to the savings is switching to the electric vehicle rate schedule as soon as you get the car. Charge the car in the middle of the night at lowest rate of 11c per kWh. Also change the time we consume energy. Laundry and pool pump at night. I built a sound proof enclosure for the pool pump. Total home electricity use went up from 500kwh to 900 kWh however the cost only went up 30$ (from 80$ to 120$)

Cost for gas for comparable gas car would be 200 per month.

Savings depends on your local utility rates available for electric cars and how you manage your other electric usage.

I can top that. We have a 13.2 kWh solar array on our roof, and produced 12.8 kWh last year and used 5.3 kWh for all electric home + 3 kWh for Tesla charging. No electric bills at our home since we moved in on 9/2012, and the Snohomish County, Washington Public Utility District (PUD) pays us through net metering $5,000/year for our electric production. Life is good up here in Washington State with solar.

I looked into solar out here in Rural Texas and the only incentive is the 30% federal tax credit. I would have to invest $30,000, get 30% of that back and would not break even on cost for 20 years due to the low cost of electricity here. So unless my kw/h cost jumps or I get more state/local incentives solar does not make sense at this point.

@Bc3000 I'm in Northern California PG&E territory too. I'm a little heavier electricity user than you so the saving is even greater. Electricity cost for me was $2600 last year. Using the PG&E calculator it would have been only $2200 with the EV-A TOU rate. That's even before I started to change heavier use to the off peak hours. The saving is more than enough to cover my MS charging.

In WA state, purchasing solar panels/inverters made in WA (Itek panels/Bluefrog APS microinverters) we get through net metering the maximum payback of $0.54/kWh incentive, with existing electric rates at $0.08/kWh. With the other incentives my solar array will be paid off in 6 more years, 7 years total since installation, so solar definetly makes sense in WA state.

Smart moves using the Solar PV panels. I've had a small 4.1kW system since we don't use much electricity. But in the northern hemisphere we get 25kW hour days making much more than we use which accumulates month after month. The last year we actually made a little money with Pacific Power and Net metering. So our driving is free and on trips its even freer with the SuperCharger stations.
My wife says since we save so much we stay at 4 or 5 star hotels helping the local economies. Not a bad way to travel.

We just had a solar evaluation done here in NC and were quite disappointed with the results. Our roof is irregular and only a small part faces south and is on a steep pitch. The best we could do is "paying off" the system in 17 years. Having low electricity costs doesn't help--I'm sure the same situation in CA where the electricity is expensive would have made more sense. For now we are going to work on replacing our lighting and cutting back on usage instead.

@proven. Also consider weatherization repairs, which have drastically cut our electric use (recommend getting blower door test, plugging major leaks through added insulation, etc.)and replacing lights with LEDs. The net affect at our home has cut our electricity use by almost 50%. Unfortunately we did these repairs after 1st sizing out solar system prior to weatherization repairs. Had I done the repairs first, we could have gotten by with a smallern system rather than the 13.2 kWh system we installed. Our current solar system gives us 153% of use, which was a waste of money, but we are feeding the grid for someone else to use.

@Tesla-David:

That's good advice, but our home is only a few years old and we built it above Energy Star ratings (insulation, windows, etc), so there is little we can do to improve with weatherization. We are currently in the process of replacing our lights with LED's so we'll see how much that helps. Even after that however, we'll probably only be able to get a solar system that can give us ~40% of use (the original numbers were 29%).

Tesla-David: as a Snohomish County resident, I'm interested in knowing specifically with whom you worked to get set up: installer, arrangements with PUD, etc. Notwithstanding my "handle," I live in Everett.

I'm in norcal and with PG&E. My monthly bill actually went down by over $50. I used to pay on an average $180 a month. Now the average bill is $120.

@SeattleSid. Our solar installer was A&R Solar, who has been great to work with. They saved me money by not having to upgrade my electrical panel in garage, which was stated as necessary by another solar installer I was talking to. This Snohomish PUD renewable energy link should get you the information you need. http://www.snopud.com/?p=1685

@proven
Have you considered ground placed options for solar panels? If your roof does not provide sufficient coverage, that might be an option to boost your solar production, or going with more efficient solar panels that give higher ratings for smaller space. Our Itek panels are not the most efficient ones but I had ample roof available, so I went with a local Solar vendor producing panels in Bellinghamn, WA.

Ground placed panels are not permitted in our neighborhood (also we don't have a lot of land). The 29% of use that we got was using the high efficiency panels by Sunpower. That tells you how little usable roof space we have.

Thanks, T-D!
