Nuclear Power - Corporate Welfare

Ahh, the things that amaze me........ from The Washington Post's Wonkblog comes the following account of corporate welfare. Yet people worry that subsidies to homeowners for roof top solar is a giveaway......


Why is the Obama administration using taxpayer money to back a nuclear plant that’s already being built?

  February 21, 2014



If nuclear power is such a good idea, why does it need financial help from U.S. taxpayers?
This week, Energy Secretary Ernest Moniz announced that the Obama administration would extend a $6.5 billion federal loan guarantee to cover part of the cost of building two new reactors at Southern Co.’s Alvin W. Vogtle site. Thursday he went to Waynesboro, Ga. to finalize the deal. Another $1.8 billion in guarantees could come soon.
The impact: Southern’s Georgia Power subsidiary, which owns 46 percent of the project, will save $225 million to $250 million because the loan guarantee will reduce interest costs. Instead of borrowing from a commercial bank, Southern can now borrow at rock bottom rates from the government’s Federal Financing Bank. And you, gentle reader, the taxpayer, take on all the risk if the project goes bust. Does the name Solyndra ring a bell?
If that’s not enough, Southern is also getting help from the federal production tax credit and other federal incentives that will ultimately save the company an additional $2 billion or so, Southern’s chief executive Tom Fanning said on a Jan. 29 conference call about earnings.
“This is a deeply subsidized project that will cost the taxpayers a lot,” said Ken Glozer, a former Office of Management and Budget senior official who is president of a consulting firm OMB Professionals.
Southern has said it didn’t need the loan guarantee to finish the project. But the guarantee doesn’t hurt.
The company also says that it will pass along the savings in financing costs to Georgia electricity ratepayers, but those ratepayers are already footing a large chunk of the reactors’ construction costs. Usually ratepayers only pay such costs once a generating station is in operation, not while it’s being built. In December, the Georgia Public Service Commission approved a three-year plan to spread out $465 million in rate increases, according to Wells Fargo Securities analysts. Southern said customer rates once the units are in service would rise between 6 and 8 percent, less than the 12 percent increase originally projected for capital costs.
This is all part of a bigger picture. Less than a decade ago, the nuclear industry was anticipating a renaissance, fueled by hopes that climate concerns about fossil fuels would trump safety worries and would help rally support beyond the industry’s usual allies. Congress tried to do its part by approving in the 2005 Energy Policy Act a $17.5 billion program of nuclear loan guarantees.
But even with that help, building a nuclear plant is extremely expensive, and for a single utility, even a large one, to undertake such a project means betting the farm, as former Duke Energy chief executive Jim Rogers once put it. Moreover, costs rose since 2005. While Congress envisioned helping half a dozen reactors or more, the program is now expected to cover only three or four.
Then, if those challenges weren’t enough, the industry was hit by the recession, competition from low natural gas prices, and the Japanese earthquake and tsunami that destroyed three reactors at the Fukushima plant and fanned safety concerns worldwide.
It wasn’t just a perfect storm. It was three perfect storms.
Moniz said the Vogtle project was “not only a major milestone in the Administration’s commitment to jumpstart the U.S. nuclear power industry, it is also an important part of our all-of-the-above approach to American energy as we move toward a low-carbon energy future.”
Many experts say it’s not the sort of milestone Congress and the industry once had in mind. The nuclear industry is nearly halfway through a more than $30 billion construction program, with the two new reactors being built in Georgia, and three others in South Carolina and Tennessee. Like the ones in Georgia, a pair under construction in South Carolina can rely on a state law allowing costs to be passed along to customers while construction is in progress. The fifth is being built by the Tennessee Valley Authority.
But while five reactors are under construction, four others have closed down or announced plans to close down. Two cited competition from natural gas plants and two others faced large repair and upgrading costs. The renaissance seems to be stillborn.
Proponents of nuclear power are still trying, though, and they say that the loan guarantee and production tax credits aren’t any different from what wind and solar projects get. Level playing field and all that. Besides, Southern says, Solyndra was a new company with a new technology whereas Southern has been around for roughly a century and nuclear power plants have been in operation for decades.
“Loan guarantees have been in place for years and are a successful vehicle used by the federal government to ensure investment in critical infrastructure projects,” Marvin Fertel, president of the Nuclear Energy Institute, said.
The Vogtle loan guarantee had been conditionally approved by the Obama administration four years ago, and Southern is already well into construction — although it’s running about 21 months behind schedule according to the anti-nuclear group Public Citizen. (You can see photos of the project’s progress here.) The reactors are Westinghouse AP1000 models, a new generation reactor.
Wells Fargo last month lowered its earnings outlook for Southern, citing “construction risk” from the nuclear reactors as well as a modern coal plant under construction — and over budget — in Mississippi. Now that risk belongs to all of us.
“No doubt, this is a bad deal for the American people who have been put on the hook for a project that is both embroiled in delays and cost overruns and to a company that has publicly stated that it does not need federal loans to complete the project,” Allison Fisher, Outreach Director, Public Citizen’s Energy Program said. “This is a classic case of throwing good money after bad – an unnecessary and unconscionable decision to make with taxpayer money.”

Bonus fact: The reactor site in Georgia is named after the late Alvin Ward Vogtle Jr., former chairman of Southern. Vogtle was an Army Air Force pilot in World War II, and flew more than 30 missions before crash-landing in North Africa and being taken to a prisoner of war camp in Germany. On his fifth attempt, he escaped by scaling a 14-foot barbed-wire border fence and crossing to Switzerland. The character Steve McQueen played in the 1963 film “The Great Escape” was based on recollections of several veterans, including Vogtle.

Grid Parity - Tipping Point For Change


   While grid parity is where things are headed there are still many obstacles - starting with dollars and dollars of utility money to fight it. Start in Arizona to see the aggressive tactics used by utilities against grid parity. Grid parity will allow on-site power generation by independent and very small producers (a household) to be part of the discussion of the future of energy production in the United States, instead of  beening dismissed as insignificant. 
   Quality improvements and cost declines in batteries, as the article reports, are a major tipping point to make on-site surplus power generation practical for a growing number of people and businesses. While not mentioned in the article, there are recent significant performance improvements in small scale wind power production systems designed for residential rooftop mounting. With further price drops, a system that combines rooftop solar and wind electric production with battery backup becomes a practical goal for an urban dweller - not just off-the-grid back-to-the-hills people. Adding a solar hot water component further reduces off-site power needs.
    As more individual households become energy producers, the two-way potential of the grid begins to be realized. Up until now, the grid is primarily seen as a one-way street to the consumer. Deregulation has divided distribution from production but a lot of the same folks are still around and they would be happy if it stayed a one-way street. The continuing rise in on-site power production pushes the envelope though. I see two basic realities - first, less distributed power means less revenue and taxes and second, if a micro power producer wants to sell their power, they must be connected to the grid. Connection will cost money. Clearly a realignment of the present utilities vs. solar people paradigm is needed - the grid needs re-imagining with an emphasis on who is to receive the benefit - is it a democratic thing because everyone basically needs it or is it prone to corporate bottle-necks or choke points? 
   The inherent benefit of household power production is people keeping their money - the elimination of the massive wealth transfer from individuals to the corporations that control electricity production and distribution. People do not give up money streams without resistance. Corporations will go to great lengths to protect what they consider to be theirs. Grid parity is change - for forward looking people, it is a key element in a tipping point that can have significant effects on corporate and government revenues. Just as there are currently winners and losers, there are winners and losers to come. Hopefully these issues will soon be more commonly part of the discussion for everyone.
      

Grid parity: Why electric utilities should struggle to sleep at night

By Matt McFarland, Updated: March 25 at 9:02 am

What’s good news for those concerned with climate change, and bad news for electric utilities? That’s grid parity, which is sometimes called socket parity. It exists when an alternative energy source generates electricity at a cost matching the price of power from the electric grid.
As grid parity becomes increasingly common, renewable energy could transform our world and slow the effects of climate change. Advances in solar panels and battery storage will make it more realistic for consumers to dump their electric utility, and power their homes through solar energy that is stored in batteries for cloudy days.
“I think the grid gets disrupted,” said NRG Energy chief executive David Crane. “The only question is do you want to be the disruptor or do you want to get disrupted.”
Our world is increasingly cordless, and power appears likely to follow. While we’re not there yet, the momentum behind distributed energy is building.
The Rocky Mountain Institute has said that tens of millions of commercial and residential customers will have grid parity by 2030 and perhaps 2020. Hawaii is already there as a result of high energy costs associated with being an island.
Other estimates are more aggressive. A 2013 Deutsche Bank report said that 10 states are currently at grid parity: Arizona, California, Connecticut, Hawaii, Nevada, New Hampshire, New Jersey, New Mexico, New York and Vermont. According to a 2013 note by Citi Research, Germany, Spain, Portugal and Australia have reached grid parity.
This shift has benefited from a dramatic drop in the price of solar panels, which dropped 97.2 percent from 1975 to 2012, according to GTM Research.
For electric utilities to truly be challenged, batteries are just as important as solar panels. With batteries excess energy could be stored. Tesla announced in February it’s building a gigafactory, which it envisions producing more lithium ion batteries by 2020 than were produced worldwide in a 2013. The scale of the operation should drive down prices further (Tesla estimates over 30 percent). Some of these batteries will be used by SolarCity, a leader in installing residential solar panels.
SolarCity has a pilot program in California, in which batteries store solar power. It has complained that electric utilities are slowing its rolloutNRG Energy hopes to have a similar product available by the end of 2014.
If utilities are dragging their feet on SolarCity’s initiative, it’s easy to understand why. As solar energy gets cheaper, traditional electric utilities are doing the opposite. The cost of maintaining the electric grid has gotten more expensive, but reliability hasn’t improved. The investments of electrical utilities appear to be poorly spent.
If customers leave electric utilities, it starts a downward spiral. Fewer customers will mean higher rates, which encourages remaining customers to jump ship for a solar-battery system.
Electric utilities appear poorly equipped for how technology will transform the energy industry. For years there hasn’t been an incentive to innovate, in part due to a lack of competition. Plus, making their product cheaper means less revenue, so why innovate?
Meanwhile, energy upstarts are led by forward thinkers with disruptive track records and eyes on society’s big problems, such as climate change and our dependence on fossil fuels for energy. SolarCity chairman Elon Musk co-founded PayPal and leads Tesla, which could transform the auto industry.
NRG’s Crane speaks of having his company mentioned in the same breath as Amazon, Apple, Facebook and Google. It’s radical to imagine anyone feeling passionate about their source of power, but environmental concerns may make it common soon. New devices such as Nest’s popular thermostat are making consumers rethink what to expect from the companies and gadgets that manage their energy.
Crane highlighted the climate change concerns in a recent letter to shareholders: “The day is coming when our children sit us down in our dotage, look us straight in the eye, with an acute sense of betrayal and disappointment in theirs, and whisper to us, ‘You knew… and you didn’t do anything about it. Why?’”

Roof Top Solar And The Grid - Limits To Smartness?


Solar Power Growing Pains: How Will Hawaii And Germany Cope With The Boom In Alternative Energy?

on December 23 2013 2:51 PM


  • Hawaii Solar power 2013

Is clean energy a victim of its own success, or is the transition from fossil fuels to alternative energy just going through some natural growing pains? However you spin it, in places like Hawaii and Germany, rooftop solar panels are popping up like weeds – but at a rate that might be too fast for utility companies to handle.
Solar panel setups can often supply enough juice to power a home, and more – with any excess electricity fed back into the grid. But this makes managing the flow of power a bit more difficult for the utility, compounded by the fact that solar power generation can fluctuate with changes in cloud cover. The result can be either a sudden draw on the grid on cloudy days, or a potentially overloading power surge on unexpectedly sunny days. Not every grid is able to cope.
In Hawaii, solar power-generating capacity has doubled just about every year since 2005, according to the Honolulu Star-Advertiser. But the utility company and the grid are struggling to keep up with this expansion. This September, the Hawaiian Electric Co. (HECO) told customers that they could no longer guarantee that certain residential solar photovoltaic (PV) systems could be interconnected with the utility grid. HECO says it’s worried that the solar power boom might lead to instability if the power generated by homeowners’ panels exceeds the output from local power plants.
"We can't allow circuits to become dangerous," Peter Rosegg, a HECO spokesman, told ClimateWire. "We can't allow circuits to become unreliable because there's too much PV on those circuits."
Many Hawaiians are frustrated. Take William Walker, who spent $35,000 for a rooftop solar PV system for his Oahu home, only to be left off the grid thanks to the new HECO policy. Now he has to keep paying his monthly $250 electric bill to HECO along with the $300 monthly payments on his solar panels. Walker told ClimateWire that he's not completely buying HECO’s explanation for the policy change.
“My belief is it's purely profit-motivated, to keep people away from PV and keep them on the grid,” Walker said.
And Walker's situation is hardly unique. Even though HECO will be grandfathering in more than 200 customers who submitted what are called "net energy metering" agreements -- which certify that a solar power system has been installed and approved by a licensed electrical contractor -- before a September deadline, hundreds more are still left in limbo, according to Honolulu Civil Beat. It's unclear when their systems will be able to be connected up.
Other U.S. states are eyeing how Hawaii balances solar and conventional power to avoid overloading the grid.
"As an engineer, you always want to look at the worst-case scenario. Well, [Hawaii has] it," Elaine Sison-Lebrilla, a project manager for Sacramento, Calif.'s publicly owned utility, told the Los Angeles Times in November.
Though its climate might be radically different, Germany is facing a problem similar to Hawaii's in the midst of its solar boom. Experts predict that solar-generated power may soon be able to power the whole country – but only during the sunniest hours, between noon and 2 p.m. That midday bulge is problematic for the grid.
“Any further [solar] installations beyond this point could push structural solar power supply above demand and cause permanent midday grid instability,” Citigroup researcher Jason Channell wrote in a report quoted by Business Insider.
The hope may lie in smart grids that use advanced communications networks to better juggle the production of electricity from multiple sources, as well as large-scale batteries that could store excess solar power. But neither option is especially cheap. A 2009 report from NPR estimated the cost of overhauling the grid across America at somewhere between $100 billion and $2 trillion.
Some solar advocates have faith that the market will adjust as PV systems become more popular. It is for that reason, research institute Fraunhofer ISE said in a report this past September [PDF], that Germany should not try to halt the solar power boom to wait for storage technology to catch up.
“Investing in storage is first profitable when large price differences for electricity frequently occur,” Fraunhofer ISE’s Harry Wirth wrote. “Continued, further expansion in PV and wind capacity will cause prices on the electricity exchange… to sink more often and more drastically.”

Fighting For Roof Tops

From the front lines in Colorado and Arizona of the battle over how roof top solar interacts with the grid.


Solar advocates and Xcel spar over the future of rooftop solar power

An attempt to find common ground on state policies for rooftop solar started Tuesday with a sharp exchange between Xcel Energy and solar-energy advocates.
The session ended with Xcel's refusal to withdraw its proposal — which is pending at the Colorado Public Utilities Commission — to cut rooftop-solar incentives.
In turn, the representatives from Vote Solar, a solar-energy advocacy group, said they were not sure of the value of continuing the talks.
The session, hosted by the Colorado Energy Office, brought together representatives of utilities, state government and the solar-energy industry.
The goal was to try to balance the interests of utilities and the solar industry "before it degenerates into contention," said Jeff Ackermann, director of the energy office.
The contention, however, was evident in opening statements.
Xcel's concern is that the credit given to homes and businesses with solar panels that add kilowatt-hours to the grid is too high and burdens other customers, said Frank Prager, an Xcel vice president.
In a PUC filing, Xcel is calling for a cut in the credit, the so-called net-meter charge.
The credit is equal to the price a residential customers pays: 10.5 cents a kilowatt-hour.
If the credit isn't cut, Xcel wants to reduce new solar installations in its Solar Rewards program by 83 percent to 6 megawatts.
"Utilities are working to stop and slow down these innovative technologies," said Rick Gilliam, Vote Solar's director of research.
In turn, Prager objected to the proposal that how a utility conducts its business and its planning to accommodate new technology should be part of the discussion.
"This was a missed opportunity," said Edward Stern, executive director of the Colorado Solar Energy Industries Association, a trade group.
"(Gov. John Hickenlooper) got all the relevant parties to the table, and that was a great step," Stern said. "But Xcel forcing net-metering into its renewable-energy-compliance plan makes it hard to have a discussion."
Challenges to Xcel's plan must be filed with the PUC in two weeks.
"There just isn't enough time to do everything," Stern said.
The energy office is, however, planning another session.
"We are optimistic because we see that people are willing to put forward their points of view," Ackerman said in an e-mail. "The prospects for consensus should not be judged by one meeting."
