I agree. However there may be an alternative. Try looking on the web for the wholesale price of electricity. It varies by the hour.

Some utilities are forced to charge a fixed price per kilowatt for generation to foster pricing competition. Distribution and maintenance is also fixed pricing. For those utilities, it seems to me that the smart meter cannot be used to benefit these customers so afflicted. axil On Thu, Mar 14, 2013 at 5:42 PM, Jed Rothwell wrote: > Terry Blanton wrote: > > >> They should display the current (pun intended) rate so that you can >> personally choose to shed load or wash a load of clothes. >> > > They don't, but the power company sends you a magnetic sticker for the > refrigerator showing the rates and times of day, which is just as good.

I was talking about increasing it at times of low demand. More accurately, moving the new load that lots of electrical vehicles will add, to times when excess power is available. That would be e.g. when it's windy. However there is also the possibility that a parked vehicle that already had fully charged batteries could return some power if the voltage dropped below a certain level. Whether or not it did so, would depend on the car "knowing" when next it would be used, and calculating how long it would take to recharge what it had sold back to the power company. This isn't a panacea, but it would help even out supply and demand. Essentially all the nation's electric vehicles would be acting as a large battery storage for wind and solar power. That would mean that wind and solar could increase their share of the total supply. > >It's comparable to >> a free market compared to centralized control in a communist system. >> Besides who wants a centralized authority turning off the power that is >> charging >> their car?

The only difference is that mine is automatic, whereas yours is controlled by a central computer at the power company. Smart meters log exactly when you consume power, so the power company can compare this to the times when excess power was available, and charge you a lower rate accordingly. Since my method results in automatic matching, you always get the lowest possible rate. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html

Re: [Vo]:"Nuclear Industry Withers in U.S. as Wind Pummels Prices"
They have a "super-off-peak" rate for charging plug-in electric vehicles: http://www.georgiapower.com/environment/electric-vehicles/what-rate-plan-is-best-for-you.cshtml It looks like the full daytime rate is 24 cents/kWh and the super-off-peak rate is 4 cents/kWh.The super-off-peak is from 11 p.m. to 7 a.m. This is the kind of thing you can do with smart meters. This is not quite as flexible as giving the power company the ability to remotely turn off the vehicle charger, but I'll bet it is functionally about the same. - Jed

I have heard that internet connected power supplies can be turned on and off remotely to accomplish this. They are already in use in some places, to remotely reduce loads such as large air conditioners during peak hours. Georgia Power installed a smart meter at our house that charges different amounts at different times of day. It transmits data by radio.

As nuclear power is unadjustable, it leads into oversupply of electricity when solar and wind conditions are both favorable and demand for electricity is low. It is quite common misunderstanding that Greenpeace would be the reason why Germany is getting rid of nukes, but if you think even two seconds it, you realize that there must be economic reasons why Germany is getting rid of nukes. There is just no room for idealism at energy markets, because it is about big money! When the second unsubsidized solar boom starts in Europe, especially France will be in problems with its high share of unadjustable nuclear. Latest price update from Australia is that 5 kW roof-top solar with 10 kWh battery storage cost just around $130 per MWh. This is significantly cheaper than grid electricity for households in Australia. Solar panels should get cheaper around 30 % and batteries 8 % in 2013. In 2012 module price of solar fell 50 %. —Jouni

More widespread use of electric cars could make a difference here. They could have a built in voltage sensor that allowed them to automatically charge when the grid voltage rose above a certain level (which tends to happen when there is more supply than demand). Of course, they would also have to be programmed to ensure that they were recharged by a settable future time, regardless. However being able to recharge whenever there is a surplus in supply would decrease the demand for recharging power when there wasn't a surplus.

See: http://www.renewableenergyworld.com/rea/news/article/2013/03/nuclear-industry-withers-in-u-s-as-wind-pummels-prices I did not realize there is such a thing as a negative cost per megawatt (a penalty) when there is too much power available. It is a shame that wind seems to be hurting nuclear power more than it is hurting coal. Interesting quotes: The [2012 capacity] surge added a record 13,124 megawatts of wind turbines to the nation’s power grid, up 28 percent from 2011. The new wind farms increased financial pressure on traditional generators such as Dominion Resources Inc. and Exelon Corp. in their operating regions. That’s because wind energy undercut power prices already driven to 10-year-lows by an abundance of natural gas. “Right now, natural gas and wind power are more economic than nuclear power in the Midwestern electricity market,” Howard Learner, executive director of the Environmental Law and Policy Center, a Chicago-based advocate of cleaner energy, said in a phone interview. “It’s a matter of economic competitiveness.” Wind-generated electricity supplied about 3.4 percent of U.S. demand in 2012 and the share is projected to jump to 4.2 percent in 2014, according to the U.S. Energy Information Administration. . . . Wind power has two advantages. Green energy laws in many states require utilities to buy wind energy under long-term contracts as part of their clean-energy goals and take that power even when they don’t need it. Wind farms also receive a federal tax credit of $22 for every megawatt-hour generated. Thus, even when there is no demand for the power they produce, operators keep turbines spinning, sending their surplus to the grid because the tax credit assures them a profit. On gusty days in the five states with the most wind power — Texas, California, Iowa, Illinois and Oregon -- this can flood power grids, causing prices to drop below zero during times when demand is light. Wholesale electricity during off-peak hours in Illinois has sold for an average price of $23.39 per megawatt hour since Jan. 1, after hitting a record low of -$41.08 on Oct. 11, the least since the Midwest Independent Transmission System Operator Inc. began sharing real-time pricing in 2005. . . . U.S. wind installations have risen 10-fold since 2003 to 60,007 megawatts, attracting $120 billion investment that has produced new capacity equivalent to 14 nuclear power plants and enough to power 14.7 million homes, the AWEA, the industry group based in Washington, D.C., said in a Jan. 30 report. Wind’s rapid gains have created headaches for grid operators since winds often blow strongest when homes and businesses use the least amount of power: at night and during the spring and fall seasons . . . “I think this model’s got problems with it,” Patterson said in a phone interview. “There are not many examples where the product you produce actually has negative value.” Before 2006, when wind power began its latest growth spurt, negative prices were extremely rare. The phenomenon is now prevalent in parts of the Midwest, Texas and the West Coast where turbine installations are growing fastest, data compiled by Bloomberg show. “We can’t find enough demand for the amount of energy created by Mother Nature,” said Doug Johnson, spokesman for the Bonneville Power Administration, which manages the grid in the Pacific Northwest. The transmission operator, based in Portland, Oregon, paid wind operators $2.7 million last year to stay off line so it could make room for the power from hydroelectric generators handling the runoff from melting mountain snows. . . . - Jed
