Southern Company shutting some coal generation

Southern Company (SO) is reducing its coal fuming and making the rest comply with EPA regulations, and is surprised to discover that won’t cost nearly as much or take nearly as long as it complained only 8 months ago. But remember SO isn’t even abandoning coal and is shifting to big-plant baseload natural gas and nuclear while avoiding distributed solar and wind power.

Cassandra Sweet wrote for Dow Jones and the WSJ 25 July 2012, 2nd UPDATE: Southern Co. Second-Quarter Profit Up as Economy Improves,

Southern Co. plans to shut down about 4,000 megawatts of older, coal-fired power plants to comply with stricter federal pollution rules.

How much coal generation is that? SO’s Plant Scherer near Juliette, Georgia, the largest power plant in the western hemisphere, burning 12 million tons of Wyoming coal every year, is the “nation’s No. 1 producer of carbon dioxide — the heat-trapping gas that is held chiefly responsible in models of global warming” (number two is SO’s Plant Bowen near Cartersville and number three is SO’s Plant Miller in Quinton, Alabama). Each of Plant Scherer’s four plants is rated at 880 megawatts, or 3520 MW total. But don’t get your hopes up: one of those four plants is owned by Florida Power and Light and JEA of Jacksonville, Florida. Why should Florida power companies want to shut down a plant that leaves the pollution in Georgia while exporting the power to Florida?

Incumbents win GA PSC primary, face general election challengers

At least they had primary opposition, and there’s still the general election in which to challenge the Georgia PSC incumbents. Even the incumbents aren’t defending coal anymore. Keep up the pressure and maybe they’ll finally get us solar and wind energy, or, even better, we’ll elect someone who will. Steve Oppenheimer and David Staples are running in the general election.

India baseload power grid failure

Last month the U.S. grid failed due to heat wave demand, this month, it’s India’s grid. There are several common features: coal, baseload, outdated grid, and distributed renewable energy through a smart grid as the solution.

SFGate quoting NY Times, yesterday, India grid failure causes power blackout,

The Ministry of Power was investigating the cause, but officials suggested that part of the problem was probably excessive demand during the torrid summer.

Same as in the U.S. grid failure. Except India did it bigger, according to the Economic Times of India today,

The blackout which has left 600 million people without electricity in one of the world’s most widespread power failures.

Yet officials are in denial, according to the SFGate story:

“This is a one-off situation,” said Ajai Nirula, the chief operating officer of North Delhi Power Limited, which distributes power to nearly 1.2 million people in the region. “Everyone was surprised.”

Well, they shouldn’t be, if they were watching what happened in the U.S. And India gets most of its electricity from coal, whose CO2 emissions contribute to climate change, producing ever-hotter summers. Just like in the U.S.

The story includes a clue to the solution:

German solar energy increased 47% in first half of 2012

We could be doing this if we weren't throwing money down that nuclear Plant Vogtle pit by the Savannah River. We have an opportunity today to vote for Public Service Commissioners and Georgia legislators who will represent we the people for jobs, for energy independence, and for profit. Oh, and for clean air and plenty of clean water.

Chris Cottrell wrote for Reuters 26 July 2012, German renewables output hits record high in H1

Solar energy saw the biggest increase, up 47 percent from the previous year. Germany is the world's top market for power converted from solar radiation and its installed capacity accounts for more than a third of the global total.

Torresol Energy provides solar energy night and day

We have as much sun in south Georgia as southern Spain, where they’re building industrial scale solar plants.

Tafline Laylin wrote for Inhabitant, 17 July 2011, Spain’s Gemasolar Array is the World’s First 24/7 Solar Power Plant!,

Torresol Energy has overcome one of solar energy’s biggest challenges: operating when the sun doesn’t shine. The 19.9 MW Gemasolar concentrated solar power plant in Spain’s Andalucia province has two tanks of molten salt (MSES) that store heat energy generated throughout the day. Unlike normal plants that have less thermal storage or none at all, this stored energy enables Torresol to satisfy peak summer energy demand long after sunset.

So we already know how to store solar power, even without developing better batteries. There’s more in the article. About that plant:

Characteristics of Gemasolar:
  • Rated electrical power: 19.9 MW
  • Net electrical production expected: 110 GWh/year
  • Solar field: 2,650 heliostats on 185 hectares
  • Heat storage system: the molten salt storage tank permits independent electrical generation for up to 15 hours without any solar feed.

185 hectares is about 457 acres, or about one VLCIA industrial park.

Seville, Spain, is about 37 degrees north latitude. We’re at about 31 degrees. In other words, Seville is about 360 miles north of us. And we get about the same amount of sun as Seville does.

The average insolation (amount of sunlight falling on the surface) in Seville, Spain is about the same as in Valdosta, Georgia: about 4.85 kWh/m2 per day.

Here’s a month-by-month comparison using Solar Electricity Handbook 2012 Edition. They haven’t heard of Valdosta, so I used Macon. You remember Macon, where it was 110 degrees June 30th.

WhenJan Feb Mar Apr May JunJul Aug Sep Oct Nov Dec
Seville 4.16 4.76 5.68 5.81 5.98 6.49 6.90 6.77 6.01 4.78 3.96 3.63
Macon 3.76 4.24 5.03 5.52 5.58 5.16 5.24 5.07 4.84 4.96 4.18 3.73

Some months, Sevilla has a bit more sun. But in part of the fall, we have more sun.

Maybe we should start thinking bigger around here. And if we’ve got the sun for a big solar plant, we’ve got the sun for a lot of little rooftop solar panels. How about if we put Valdosta, Lowndes County, and south Georgia on the solar map so everyone will hear of us?

Arrogance of (Georgia) Power —Michael Noll

Received yesterday on Smart Metering in Finland Compared to Georgia Power; also as a facebook note. -jsq

ONLY a monopoly like Georgia Power can proclaim to be “environmentally responsible” yet operate some of the worst coal power plants in the nation. Its Scherer Plant near Macon even leads the pack in regard to greenhouse gas emissions. Do they not understand the reality of global warming? Do they not notice ongoing drought conditions throughout the country (see http://droughtmonitor.unl.edu/)? And why, in the context of these drought conditions, are they still investing in technologies (e.g. coal, nuclear, biomass) that need enormous amounts of water for cooling purposes?

ONLY a monopoly like Georgia Power can claim to “care” for the well being of our society when they operate the nation’s largest biomass incinerator, run the nation’s worst coal firing plant, and are pushing for new nuclear power plants. Have they not heard of Fukushima, Chernobyl, and Three Mile Island? How can they still ignore the mounting evidence in regard to the side-effects of the vast pollution coming from their coal and biomass plants (see http://www.wiregrass-ace.org/linked/second-opinion.pdf)?

ONLY a monopoly like Georgia Power can pretend to “respect” its customers when it forces them to pay for the construction of nuclear power plants nobody wants, or when it chooses intimidation as a tool to push through “smart meters”. The notion that you can’t have electricity without “smart meters” is not only ludicrous but reminds one on “leadership qualities” you expect to find in North Korea but not in the US. By the way, one should note that states like California have given their customers the possibility (dare I say right?) to “opt out” (see http://www.treehugger.com/clean-technology/more-california-utilities-required-let-customers-opt-out-smart-meters.html ).

PS: In case anyone wonders, I am not differentiating between Georgia Power and the entity that controls it: Southern Company.

The Emperor’s New Clothes —Michael Noll

The VDT apparently declined to print this LTE submission. I added the links and images. -jsq

When I opened a recent “Sunday Business” section of the Valdosta Daily Times I was expecting to see a thorough discussion of the pros and cons of smart meters. After all, the headline read: “Smart Meters — Fact or Fiction?” What I found, however, was quite different. In case you missed it, here a summary of the highlights:

According to Georgia Power “concerns about smart meters are nothing more than myths.” These concerns range from health risks and increased bills to an invasion of your privacy and house fires started by electrical shorts. Myths or not, the best way to counter customers’ concerns would be to provide studies that, for example, show that smart meters are less dangerous than cellular phones or that electricity bills have not increased as a result of smart meters. However, customers only get assurances which, frankly, do nothing to dispel existing concerns.

Georgia Power also claims that it is using smart meters to be more environmentally

Professor unrepentant in latest fracking payola case

Apparently the natural gas industry pays professors to greenwash their polluting product, like back in the hey-day of radio record companies used to pay disk jockies to play their records. Remember: natural gas from fracking is the main thing Southern Company and Georgia Power are switching to from coal (not that they’re even abandoning coal, just rebranding it as “21st century coal”). That and their nuke boondoggle at Plant Vogtle. All approved by the Georgia Public Service Commission, all of whose members apparently accept massive direct or indirect contributions from the utilities they regulate. Two GA PSC Commissioners slots are up for election right now.

The professor most recently found to be in the pay of a fracking company when he reported on fracking is unrepentant. Terrence Henry wrote for State Impact Texas yesterday, Texas Professor On the Defensive Over Fracking Money

So the questions remaining are: Why didn’t Groat disclose this in the study? And did he fail to tell anyone at the University about it?

The professor would not agree to an interview, but in an email to StateImpact Texas he says the Public Accountability Initiative report is “a mixture of truths, half truths, and unfounded conclusions based [on] incorrect interpretations of information. I don’t want to discuss it.”

The University of Texas requires that financial conflicts of interest be disclosed by employees when it has “potential for directly and significantly affecting the design, conduct, or reporting of … research or is in an entity whose financial interest appears to be affected by that research.”

Dean Sharon Mosher of the Jackson School of Geosciences says that Groat submitted the financial conflict of interest form to her office in previous years, but that he had not done so this year. “I was not aware that he was still a member of the board,” Mosher tells StateImpact Texas. “Had I known he was still a member of the board and being paid, I would have insisted that he disclosed it.”

What report? Follow the links in here. Terrence Henry wrote for State Impact Texas 23 July, Fracking Company Paid Texas Professor Behind Water Contamination Study,

Earlier this year, a study led by Dr. Charles “Chip” Groat for the Energy Institute at the University of Texas at Austin made headlines for saying there was no link between fracking and groundwater contamination. (When we reported on the study in February, we noted that the study also found some serious issues around the safety and regulation of fracking that weren’t getting much press coverage.)

But according to a new report out today by the Public Accountablitiy Initiative (PAI), a nonprofit watchdog group, the conclusions in Groat’s report aren’t as clear cut as initially reported. And Groat himself did not disclose significant financial ties to the fracking industry.

Groat, a former Director of the U.S. Geological Survey and professor at the Jackson School of Geosciences at the University of Texas at Austin, also sits on the board of Plains Exploration and Production Company, a Houston-based company that conducts drilling and fracking in Texas and other parts of the country. According to the new report (and a review of the company’s financial reports by Bloomberg) Groat received more than $400,000 from the drilling company last year alone, more than double his salary at the University. And one of the shales examined in Groat’s fracking study is currently being drilled by the company, the report says.

Since 2007, Groat has received over $1.5 million in cash and stock awards from the company, and he currently holds over $1.6 million in company stock, according to the PAI report. (Update: we clarified with PAI, and that $1.6 million in stock comes from the stock awards over the years. PAI says Groat’s total compensation from the company is close to $2 million.)

And it gets worse from there: rough drafts published, unsubstantiated peer review claims, etc.

This isn’t an isolated case:

This isn’t the first time that academic studies of drilling have been called into question because of industry ties. In an earlier report on a State University of New York at Buffalo study on fracking’s environmental risks, Public Accountability Initiative found that it “suffered a number of critical shortcomings” and the “report’s authors had strong industry ties.”

And in today’s investigation from Bloomberg, they found other instances of industry influence and financial ties at Pennsylvania State University and University of Wyoming.

Do we want to trade air pollution by coal for groundwater pollution by fracking? When we have a better future already at hand through conservation and efficiency along with solar and wind power?

Heat shuts baseload nuclear plants

Baseload nuclear plants can’t take the heat! Meanwhile, zero stories of solar plants shutting down due to heat. Quite the opposite: more sun, more solar power!

Scott DiSavino wrote for Reuters 18 July 2012, Four U.S. power reactors shut & NYC sweats during heat wave,

Several nuclear plants on the U.S. East Coast shut down by early Wednesday and New York’s Consolidated Edison power company reduced the voltage in parts of Manhattan as the obsessive heat wave stressed the region’s power system.

Despite the shutdown of four giant nuclear reactors in New York, Pennsylvania, Maryland and South Carolina, the power systems delivered the juice needed by the regions’ homes and businesses to keep air conditioners humming on the projected last day of a brutal heat wave.

Then there’s this excuse:

Although the heat makes it more difficult to use the warmer river water to cool power plants and can stress power lines due to high usage, the reactors did not necessarily shut due to the heat.

They shut down due to faulty sensors, leaks, or unknown causes, and that’s somehow better?

Meanwhile, solar just keeps generating. I’ve never heard of a wind plant shutting down due to heat, either.

Remind me again, why is Georgia Power’s and Southern Company’s bet-the-farm risk on new nukes at Plant Vogtle a good idea? Wasn’t it supposed to be about dependable power?

Austin Energy’s Biomass Buyer’s Remorse

Georgia Power’s parent Southern Company (SO) is bragging about selling a 100 MW biomass plant to Austin Energy. Funny how SO’s press release doesn’t mention Austin Energy’s buyer’s remorse. Let’s see why Austin Energy should regret buying biomass.

SO PR 18 July 2012, Southern Company brings nation’s largest biomass power plant on line: Nacogdoches facility contributes to Austin Energy renewables goal

Southern Company SO announced today that the nation’s largest biomass plant is putting electricity on the grid in Texas. Southern Company President, Chairman and CEO Thomas A. Fanning joined state and local dignitaries today at the company’s Nacogdoches Generating Facility to mark commercial operation for the 100-megawatt unit.

Austin Energy is receiving energy from the plant through a 20-year power purchase agreement.

The PR goes on about local jobs and taxes, which could have been produced through building solar or wind generation. How much did that biomass plant cost Austin Energy? Funny how that’s not in the PR!

The City of Austin owns Austin Energy, and the Mayor and City Council are its Board of Directors. Vicky Garza wrote for the Austin Business Journal 20 July 2012, Austin Energy’s buyers remorse for biomass,

Austin City Council Member Mike Martinez wouldn’t mind a do-over on the $2.3 billion, 20-year energy contract the council approved in 2008.

The contract calls for Austin Energy to buy the entire output from the Nacogdoches Generating Facility, a 100-megawatt wood-waste-fueled biomass power plant.

“When the contract was initially brought to Council, it appeared to be a good deal to help us reach our adopted goals for renewables,” Martinez said.

It seemed like a good idea at the time.

$2.3 billion for 100 MW is about $23 per Watt. How does that compare to the 30 MW Webberville solar farm Austin Energy opened this year? Continue reading →
