DOE Study: Off-Peak Electricity Production Could Power Most of USA's Vehicles

From The Auto Channel:
RICHLAND, Wash. --– If all the cars and light trucks in the nation switched from oil to electrons, idle capacity in the existing electric power system could generate most of the electricity consumed by plug-in hybrid electric vehicles. A new study for the Department of Energy finds that "off-peak" electricity production and transmission capacity could fuel 84 percent of the country's 220 million vehicles if they were plug-in hybrid electrics.

Researchers at DOE's Pacific Northwest National Laboratory also evaluated the impact of plug-in hybrid electric vehicles, or PHEVs, on foreign oil imports, the environment, electric utilities and the consumer.

"This is the first review of what the impacts would be of very high market penetrations of PHEVs, said Eric Lightner, of DOE's Office of Electric Delivery and Energy Reliability. "It's important to have this baseline knowledge as consumers are looking for more efficient vehicles, automakers are evaluating the market for PHEVs and battery manufacturers are working to improve battery life and performance."
More later.

UPDATE: One of our nuclear engineers, Adrian Heymer, sent us the following note:
If the nation moves more toward a plug-in transportation system, which some London stores had in the 1950s and 1960s for delivery vehicles, we would need a lot more baseload generation.
True enough. And more baseload generation means you have just two options: coal or nuclear energy. For more, visit FuturePundit and The Speculist. Thanks to Instapundit for the pointer.

Electric substitution would certainly require some changes in driving habits unless the issue of range and recharge time is resolved so that electrics are comparable to what people are used to now. I think I can manage okay on routine driving. But I'd be hurting on the occasional long-distance trip. Now I can go 500-600 miles, and "recharge" in five minutes at the gas pump. Very convenient for distance travel.

I believe the earlier commenter might be confusing plug-in hybrids and all electric vehicles. Plug-in hybrids still have internal combustion engines that can be quickly "recharged" with gas, just as in a normal hybrid. However, for long trips I suspect the added batteries that go with plug-ins would be largely dead weight.

I was thinking of all-electric, since that really is the way to go if we are serious about getting off of the foreign petroleum addiction. Hybrids still have the gasoline component so while we may be stretching the supply of that somewhat with hybrids, we'll still need it.

Now hydrogen, OTOH, would really do the trick. Decent range, quick "recharging", electric substitution, all in one package.
Well, this electricity (which I assume would be provided by peakers in off-peak hours) is a lot more expensive, no? Aren't we talking ~$0.15/kWh?

Wouldn't plug-in hybrids also work a lot better with flat-fee billing (which could easily be supported by a higher gas tax)?

And what about summer vs. winter gasoline blends?

Stewart:

Why would you use peakers in off peak hours? If there is a new steady state demand like car charging, it would make more sense to simply operate baseload plants at a higher capacity factor while you are building new ones as the loads gradually increase. That process would be rather slow since automobile replacement takes a number of years.

I find it interesting that Amory Lovins likes plug in hybrid and uses the "cheap overnight rates" as part of his economic computations that show how quick the payback can be. Of course, he fails to mention that those cheap overnight rates are available because the operating cost of nuclear plants is about 1.7 cents per kilowatt hour and most of that is not even dependent upon whether or not the plant is running. The actual marginal cost of continuing to produce power in a nuclear plant compared to shutting it down is on the order of 0.5 cents per kilowatt hour - the cost of the fuel itself.

With the average fuel cost of a coal plant is on the order of 1.2 cents per kilowatt hour, while a gas plant in a market with $8 per million BTU gas burns fuel costing about 6.4 cents per kilowatt hour (assuming a reasonable heat rate of about 8,000 BTU per kilowatt hour).

Of course, I recognize that there is a big difference between "cost" and "retail price".

Hey have you seen that there are real e-cars being made and marketed ? Check http://teslamotors.com ... (i;m not related to that company, just a fan of e-cars :) )

MOstly consider what a torque of e-motor does w.r.to a combustion engine ;-)

The occasional long distance trip problem could be solved with a tow behind APU or a fossil fuel rental car. The money you save on fuel cost would pay for the rental car. If EV manufacturers can agree on a standard a tow behind APU could become an rental item.

Rod, at least Loving understands that you need a power plant to provide those "cheap overnight rates". I had a debate on a blog once with a no-nukes type who said his plan was to drive an electric car during the day and recharge it at night from his solar panels. Dontcha just love it...

That's precisely my point. "Off-peak electricity production could power most of USA's vehicles"--but only if you're willing to pay ~$0.15/kWh. There's a reason why these peakers aren't already being run during off-peak hours--which sort of defeats the point of the post.
Also, most of these peakers burn oil or gas--which might as well be burned in car engines. And what happens when somebody wants to recharge their car during peak hours--say, someone comes home at 6:30 and plugs in their car, then goes inside and turns on five lights and the microwave? There's no advantage to using peakers in off-peak hours to generate electricity for plug-in hybrids.

Uh, I might be missing something here in the debate, but aren't off-peak rates lower than normal rates because of the high supply and low demand during the non-business hours. If the entire country were to "jack-in" at night to charge their cars, the increase in demand would result in less available supply, which would tend to close the gap between peak and off-peak rates.

The natural analogy here is the cellular phone market. Remember when "free" calls started at 7pm -- then 8pm -- then 9pm. I don't want to have to wake up in the middle of the night just to plug in my car.

Don't get me wrong, I love my hybrid as much as the next guy (as long as I'm not on the highway), but I also miss my V8 (first car, what can I say).

I think there's enough room in the considerable future for traditional and hybrid drivetrains to share the roads (as long as the other hybrids join me in town and stay off the highways).

As long as there is diversity in engine and drivetrain types, we may just be able to create a win-win solution in the form of reasonable gas and electric rates.

There seems to be a lot of confusion here in regard to what is actually being talked about. This is about Hybrid electric vehicles using off peak unutilized electricity to maximize the efficiency of power generation and get the added bonus of the first 20 commuter miles coming from that. Then you would be back in gasoline mode. Its a matter of increased efficiencies...not a total replacement or an all electric vehicle.

Fluor Invests in NuScale

You know, it’s kind of sad that no one is willing to invest in nuclear energy anymore. Wait, what? NuScale Power celebrated the news of its company-saving $30 million investment from Fluor Corp. Thursday morning with a press conference in Washington, D.C. Fluor is a design, engineering and construction company involved with some 20 plants in the 70s and 80s, but it has not held interest in a nuclear energy company until now. Fluor, which has deep roots in the nuclear industry, is betting big on small-scale nuclear energy with its NuScale investment. "It's become a serious contender in the last decade or so," John Hopkins, [Fluor’s group president in charge of new ventures], said. And that brings us to NuScale, which had run into some dark days – maybe not as dark as, say, Solyndra, but dire enough : Earlier this year, the Securities Exchange Commission filed an action against NuScale's lead investor, The Michael Kenwood Group. The firm "misap

An Ohio School Board Is Working to Save Nuclear Plants

Ohio faces a decision soon about its two nuclear reactors, Davis-Besse and Perry, and on Wednesday, neighbors of one of those plants issued a cry for help. The reactors’ problem is that the price of electricity they sell on the high-voltage grid is depressed, mostly because of a surplus of natural gas. And the reactors do not get any revenue for the other benefits they provide. Some of those benefits are regional – emissions-free electricity, reliability with months of fuel on-site, and diversity in case of problems or price spikes with gas or coal, state and federal payroll taxes, and national economic stimulus as the plants buy fuel, supplies and services. Some of the benefits are highly localized, including employment and property taxes. One locality is already feeling the pinch: Oak Harbor on Lake Erie, home to Davis-Besse. The town has a middle school in a building that is 106 years old, and an elementary school from the 1950s, and on May 2 was scheduled to have a referendu

Wednesday Update

From NEI’s Japan micro-site: NRC, Industry Concur on Many Post-Fukushima Actions Industry/Regulatory/Political Issues • There is a “great deal of alignment” between the U.S. Nuclear Regulatory Commission and the industry on initial steps to take at America’s nuclear energy facilities in response to the nuclear accident in Japan, Charles Pardee, the chief operating officer of Exelon Generation Co., said at an agency briefing today. The briefing gave stakeholders an opportunity to discuss staff recommendations for near-term actions the agency may take at U.S. facilities. PowerPoint slides from the meeting are on the NRC website. • The International Atomic Energy Agency board has approved a plan that calls for inspectors to evaluate reactor safety at nuclear energy facilities every three years. Governments may opt out of having their country’s facilities inspected. Also approved were plans to maintain a rapid response team of experts ready to assist facility operators recoverin
