Fracking water

Yet another reason why we should take water into account in any development plan: fracking for shale gas uses huge amounts of water, competing with everything else, maybe even using more than power plants and cities.

Delaware Riverkeeper and Protecting Our Waters wrote for Waterkeeper Alliance today, The Water Footprint of Shale Gas Development,

Recent studies examining potable water supplies on a global scale, the current trends in American water consumption and the causes of depletion of this essential resource are helping us to understand that the footprint of shale gas development expands indefinitely when measured in water….

Of the seven nations where the groundwater footprint is greatest, the U.S. is one of the fastest speeding towards disaster. According to Cynthia Barnett’s Blue Revolution, scientists say the 20th century was the wettest in a thousand years and now drier times are ahead.[3] This means that many of the management schemes we use now—based on 20th C planning—need to be changed to avoid catastrophe. So the 410 billion gallons of water America uses every day will suck the nation dry if we don’t stop over-tapping nearly every river and aquifer.

The biggest U.S. users are power plants and agriculture with private

Germany Added 543 MW of Solar Power Capacity in July

While we in Georgia were still pouring money down that nuclear pit near the Savannah River, Germany has been getting on with real renewable energy. We could have deployed almost that much solar power with just the cost overruns so far at Plant Vogtle.

Nicholas Brown wrote for Clean Technica 8 September 2012, Germany Added 543 MW of Solar Power Capacity in July,

According to Matt McDermott of Treehugger: “[In] the first half of 2012 Germany has installed just over 4.37 gigawatts of grid-tied solar power. Remarkably just about 1.8 GW of that happened in June alone (perhaps even more remarkable, this isn’t even a record amount for one month in Germany).”

The amount of solar power capacity added in June was much more than July’s, but July’s was still impressive. July’s addition brings Germany’s total installed capacity for the first half of 2012 to 4,900 MW (4.9 GW).

This impressive solar installation rate had a lot to do with Germany’s famous Feed-in Tariffs (FIT), but it also had a lot to do with Moore’s Law, illustrated by that graph of cost per kilowatt rapidly going down.

543 MW? That’s more than the 330 MW of solar the $913 million cost overrun at Plant Vogtle in the first half of 2012 could have bought. 1800 MW in June and 543 MW in July? That’s 2343 MW, which is more than the entire rated 2200 MW output of Plant Vogtle 3 and 4 put together, if they ever get built. Sure, the sun doesn’t shine all the time, but in the years until the nukes ever get built (if ever), how much solar could we deploy at the rate of one Vogtle unit equivalent a month?

Hey, maybe we should cancel Plant Vogtle and deploy solar instead! Maybe Georgia Power and Southern Company will realize their big bet has already gone bad. Or maybe we should elect some Public Service Commissioners and legislators who will get them to realize it.

Change the Atomic Energy Act? How about change the Georgia Electric Territorial Act?

In reaction to the NRC denying a nuclear permit for Calvert Cliffs, some nuclear backers suggest changing the Atomic Energy Act of 1954 to permit majority foreign ownership of nuclear reactors. What will they suggest next? Asking Iran to invest in U.S. nukes?

Steve Skutnik wrote for http://theenergycollective.com 5 September 2012, A cost-free way to open up nuclear investment,

If this seems entirely backward in a world of global production and investment, that’s because it is. The current regulation is an artifact of the Atomic Energy Act of 1954, which first authorized private ownership of nuclear facilities. (Prior to this—per the Atomic Energy Act of 1946, all nuclear technology was considered a state secret, during the short time in which the U.S. enjoyed a monopoly on the technology.)

Is there any real compelling reason for restrictions on foreign ownership and investment in nuclear facilities to exist at a time when the U.S. holding a monopoly on the technology has long since passed? Issues of safety here of course are irrelevant—the facilities would be licensed and regulated by the NRC, just as any other nuclear facility is now. About the only salient objection is the political one—i.e., the implications of a foreign entity maintaining controlling ownership in key infrastructure. (Although it’s hard to see anyone getting particularly upset about the reverse—U.S. entities owning a controlling stake in infrastructure in other nations.)

Yeah, sure, strict regulation will deal with that, just like it prevents fracking from setting drinking water on fire, or BP from poisoning the Gulf. The new NRC head is maybe well-meaning, but it’s the same NRC that gave Vogtle 1 a clean bill just before it had to shut down and the same NRC that’s ignoring cancer in Shell Bluff.

Oh, by the way, the article gets to the main point eventually:

NRC rejects nuke permit for EDF in Maryland

French nuclear operator Électricité de France (EDF) was denied a license last week for the proposed Calvert Cliffs nuclear reactor in Maryland, because the Atomic Energy Act of 1954 prohibits majority foreign ownership of nuclear plants. EDF now has 60 days to find a U.S. partner, or give up the project. Who could the possible suitors be? Hint: think southeast.

The handwriting was on the wall two years ago when Constellation Energy pulled out of the project. Jim Polson and Alan Katz wrote for Bloomberg 10 October 2010, Constellation Drops Nuclear Plant, Denting EDF’s U.S. Plans,

Constellation Energy Group Inc. pulled out of negotiations on a $7.5 billion loan guarantee to build a nuclear reactor in Maryland with Electricite de France SA, potentially damaging the French utility’s U.S. expansion plans and the companies’ partnership.

The cost of the U.S. government loan guarantee that the companies’ joint venture, UniStar Nuclear Energy, would need to build the Calvert Cliffs 3 reactor is too high and creates too much risk for Constellation, the Baltimore-based utility said in a statement yesterday. The statement said the next step is up to EDF. Enlarge image U.S. Deputy Energy Secretary Daniel Poneman

In a letter Oct. 8 to Daniel Poneman, deputy secretary of the U.S. Department of Energy, Constellation said it received a government estimate that the venture would have to pay about $880 million to the U.S. Treasury for the loan guarantee, “dramatically out of line with both our own independent assessments and of what the figure should reasonably be.”

Constellation’s decision may make it more likely that the U.S. utility will exercise a put option forcing EDF to buy as much as $2 billion of Constellation’s non-nuclear power plants, said Ingo Becker, head of utilities sector research at Kepler Capital Markets.

“EDF very clearly said if they exercise the put, this thing is over,” Becker said. “Constellation may have just turned around the calendar and pulled out of the new build before exercising the put, anticipating EDF’s reaction.”

In a letter Oct. 8 to Daniel Poneman, deputy secretary of the U.S. Department of Energy, Constellation said it received a government estimate that the venture would have to pay about $880 million to the U.S. Treasury for the loan guarantee, “dramatically out of line with both our own independent assessments and of what the figure should reasonably be.”

Meanwhile, Southern Company is still trying to reduce what it has to pay for its $8.3 billion federal loan guarantee.

New NRC head says agency is standing up for public health and safety

Sounds to me like the NRC is not telling its new chief everything. For example, what about Vogtle unit 1 shutting down right after it passed an NRC review? What about cancer in Shell Bluff, Georgia, near the reactors?

Mike M. Ahlers wrote for CNN 14 August 2012, New NRC chair vouches for agency’s independence, states goals

Allison Macfarlane said Tuesday she has confidence in the agency and its independence from the nation’s 104 commercial nuclear power plants.

“I have some strong initial impressions of the agency, and one is that I’ve been very impressed with the staff and their dedication to safety, and their willingness to stand up to industry when they believe a situation is not safe,” Macfarlane said in a wide-ranging discussion with reporters.

“So I’m actually quite assured that the agency is completing its mission of protecting public health and safety,” she said. “They take safety issues very seriously. They take their role as regulators very seriously and the public should be assure that they have the public’s best interests in mind.”

Macfarlane said she hopes to build public confidence in the agency by improving communication, increasing transparency and making NRC documents understandable. “Some of them are rather opaque,” she allowed.

She has said some slightly more impressive things back before she was appointed. Continue reading →

Wind second only to natural gas in 2011 added capacity

Looks like Southern Company (SO) bet on the wrong horse.

David Danielson wrote for DoE 14 August 2012, A Banner Year for the U.S. Wind Industry,

The report finds total U.S. wind power capacity grew to 47,000 megawatts by the end of 2011 and has since grown to 50,000 megawatts, enough to power 12 million homes annually — as many homes as in the entire state of California. And as wind energy capacity has grown, more and more wind turbines and components like towers, blades, gears, and generators are “Made in America.” Nearly 70 percent of all of the equipment installed at U.S. wind farms last year came from domestic manufacturers, doubling from 35 percent in 2005.

Why should SO worry? Wind only came in second in added capacity. Because of this:

In addition to strong gains in domestic wind manufacturing and capacity, the report finds that as wind technology improves, costs are coming down. Technological innovations are helping make longer and lighter wind turbine blades, while improving turbine performance and increasing the efficiency of power generation. At the same time, wind project capital and maintenance costs have continued to decline.

And wind doesn't even have Moore's Law going for it as much as solar does, plus solar is usable in more areas than wind. Add wind and solar and why do we need much natural gas? (Or any coal or nuclear?)

Where would Georgia Solar Utilities Inc. get enough land for 80 MW solar generation?

Plant Branch in Georgia Where will Georgia Solar Utilities Inc. get the 2,200 acres it says it needs to build 80 MW of solar generation? Well, it’s supposed to be “adjacent to Georgia Power Co’s coal-burning Plant Branch near Milledgeville, Ga.”, so let’s look there.

Plant Branch Location Map A brochure on Plant Branch by Georgia Power (undated, but last date mentioned is 1998, so I’m guessing 1999) says:

Located on 1,900 acres on Lake Sinclair in Putnam County between Eatonton and Milledgeville, Plant Branch was the first million-plus-kilowatt electric generating station to operate on the Georgia Power system. It is named for Harllee Branch Jr., former chairman of the board of Southern Company and president of Georgia Power. Construction on the plant began in 1961, and by the summer of 1969, Coal pouring onto pile four units were in operation. The 1,539,000 kilowatts generated by Plant Branch provides enough electrical power for 342,000 households.

And now Plant Branch will be among the first to close coal-generating units. According to Melissa Stiers for GPB News 12 July 2011, Georgia Power Closing Three Plants,

Two coal fired units at Plant Branch in Milledgeville will close in 2013. That’s a result of federal regulation tightening air pollution controls. The company has said it’s too costly to upgrade those units.

Plant Branch across Lake Sinclair As we know, Georgia Power’s parent The Southern Company claimed it was incompetent to deal with the new EPA regulations even though it had already announced the Plant Branch closures (amounting to about 770 MW), and later SO announced 4,000 MW of coal plant closures.

While the various news stories keep saying Plant Branch is in Milledgeville, actually, it’s on the other side of Lake Sinclair, closer to Eatonville, Plant Branch site in Putnam County qpublic map and in Putnam County. A quick glance at the Putnam County Tax Assessor database maps shows that the land parcel containing Plant Branch is 913.87 acres, much of which isn’t actually used by the plant. And Georgia Power owns a total of more than 3,000 acres adjacent to that site. So I’m guessing the 2,200 acres figure is simply around 3,100 total Georgia Power acres minus 913 acres for the present Plant Branch site.

Company to build 90 MW solar and become a utility

What to do if you can’t interest Georgia Power in building solar? Do it yourself, and do enough so you can be a utility yourself. That’s the loophole in the 1973 Electric Territorial Act that FPL and JEA use to burn coal at Plant Scherer in Georgia and export the power to Florida. Now Georgia Solar Utilities Inc. is using the loophole for a better purpose: building almost twice as much solar generation as Georgia Power’s meager 50 MW.

Georgia Solar Utilities Dave Williams wrote for the Atlanta Business Chronicle yesterday New Georgia utility pitches solar plant: A new utility is planning to build a $320 million solar power plant on 2,200 acres adjacent to Georgia Power Co’s coal-burning Plant Branch near Milledgeville, Ga.

Georgia Solar Utilities Inc. initially approached Georgia Power, a unit of Southern Co. (NYSE: SO), with a proposal to build the plant and sell it to Georgia Power through a power-purchasing agreement.

Georgia Power is retiring two coal-fired units at Plant Branch, part of a move to reduce the Atlanta-based utility’s reliance on coal.

But when Georgia Power officials declined to take part in the project last May, Georgia Solar Utilities executives decided to build the plant on their own and operate it as a new utility independent of Georgia Power.

Once cost prohibitive, solar energy has become competitive with fossil fuels because of the rising costs of coal and tighter government regulation of coal emissions, said Robert Green, founder of Georgia Solar Utilities.

“When you don’t have to buy coal or worry about environmental hangovers, it overwhelms the costs of fossil fuels, Green said Thursday after presenting the proposal to the Georgia Public Service Commission’s Energy Committee.

Some say the PSC can’t approve such a utility because of that 1973 law. I suspect that if they don’t approve this proposal, the next one will be even harder to turn down, and the next one, as they become even more competitive.

How competitive?

Nuclear plant shut for two weeks in Connecticut due to heat

Ever heard of solar panels or windmills shutting down due to heat? Me, neither. Nuclear plants, yes, such as Millstone unit 2 in Connecticut, closed for two weeks.

AP wrote today, Conn. nuclear plant unit reopens with cooler water

Connecticut's nuclear power plant has returned to full service nearly two weeks after one of its two units was forced to shut down because seawater used to cool it down was too warm.

Millstone Power Station spokesman Ken Holt said Monday that Unit 2 returned to 100 percent power Saturday. It shuttered Aug. 12 after record heat in July contributed to overheated water from Long Island Sound.

Water is used to cool key components of the plant and is discharged back into the sound. The water's temperature was averaging 1.7 degrees above the 75-degree limit.

The temperature has since dropped to 72 degrees, Holt said.

"The water temperature cooled sufficiently to support operations and that, combined with the weather forecast, has given us the confidence to restart," he said.

Wait, wasn't the whole point of big distributed baseload power plants supposed to be reliable dependable power?

Millstone provides half of all power in Connecticut and 12 percent in New England.

Some scientists believe the partial Millstone shutdown was the first involving a nuclear plant pulling water from an open body of water. A few nuclear plants that draw water from inland sources have powered down because of excessively warm water.

Time to think again! Distributed solar and wind power doesn't have this problem, and a smart grid can get their power where it's needed.
