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.

Solar Power Farm At New England College

   I recently saw this solar power farm at Stonehill College in Massachusetts - fantastic to see!


One of Nation’s Largest College Campus Solar Fields Being Built at Stonehill

January 6, 2014





A 15-acre solar field is being built on an unused parcel of land across from Stonehill College’s main campus on Route 138 in Easton. Scheduled to be completed early in 2014, it will be 2.7 megawatts in size and contain 9,000 solar panels which will make it the 11th (tied) largest solar installation on a college campus nationwide and the largest on a New England college campus according to the Association for Advancement of Sustainability in Higher Education (AASHE) database.
The solar field is expected to save the College over $185,000 a year or an estimated $3.2 million over the course of a 15-year contract it has signed with New Jersey-based Marina Energy.  The energy produced is expected to account for 20% of Stonehill’s electrical usage.

Protecting God’s Creation

The impetus for the solar field is not just financial. The project also aligns with Stonehill’s strategic commitment to building a culture of sustainability on campus and ties in with the College’s Catholic ethos.
“The solar field is an extension to our Catholic commitment to care for creation and sustainability. It gives further indication of our commitment, on every level, to preserving the resources that are in our care for future generations,” says Rev. James Lies, C.S.C., the College’s vice president for mission.
“As Catholics, we are called upon by God to be good stewards of the earth and the natural world. We have a responsibility to use our gifts and expertise to advocate for environmental justice and to create sustainable development options,”   explains Fr. Lies.
In 2012, Stonehill became the 12th Catholic college in the United States to sign the St. Francis Pledge, which is a public promise to protect God’s creation and the environment, and to advocate for those who are impacted the most by global climate change. The pledge is named in honor of St. Francis of Assisi who is the patron saint of the environment and of animals. 

Good Stewards

Across a variety of fronts, Stonehill has taken numerous actions towards sustainability. For example, in 2012 the College phased out bottled water usage and in 2011 created The Farm at Stonehill, which supplies local food banks, soup kitchens and other meal providers with organic, sustainably grown fruits and vegetables.
Other initiatives have included composting cafeteria waste, introducing the Zip Car car-sharing option, single stream recycling and other waste reducing programs.
Once the solar field is completed, students and visitors of the College will be able to monitor the energy output from the solar field in real time on a screen which will be housed in the College’s Shield Science Center.
In addition to the 15-acre solar field, the College has also installed roof-top solar panels on two of its facilities storage buildings and has plans to install more roof-top panels throughout campus in the future.

Sustainable Partnerships

Solect Energy of Hopkinton, MA, the leading commercial solar energy project developer in the state, is building the solar field while the entire project is being overseen by Power Management, Inc., an energy consulting firm which manages over 15,000 commercial and industrial utility meters throughout North America.
“Sustainability is very much part of our strategic plan and we are alert to new opportunities,” says Craig Binney, Stonehill’s associate vice president for finance and operations.  
Through a connection with two Stonehill alumni, David Cohen ’93 and Richard Tepper ’86, College officials met with Power Management in 2011.
“We liked what we heard and, after speaking with its Vice President Kevin Kelly, we saw an opportunity for a significant sustainable initiative Binney notes.
“Solar projects take a long time to complete and it’s necessary to have a ‘champion’ for the project and I cannot say enough about the Stonehill team, especially Craig and Jeanne Finlayson (Vice President for Finance).  Despite a few setbacks with the project along the way, they really moved things along and it has been such a pleasure working with them over these last two and a half years,” Kelly says.
Solect Energy broke ground on the project beginning this fall and expects the field to be completed over the next few months.
“It has been a pleasure working in collaboration with Stonehill, Power Management and Marina Energy on a project of this magnitude,” says Scott Howe, Partner at Solect Energy Development. “Stonehill is establishing itself as a shining example of how a college can reap the benefits of making a huge commitment to sustainability by using renewable solar energy to power its campus.”
Marina Energy, which owns and operates the field, commends Stonehill for its commitment to renewable energy.
“We credit Stonehill for its forward-thinking strategies which will put the College in a strong position to lead others in New England to a more sustainable future. As more and more institutions like Stonehill College turn to cleaner, renewable sources of energy, the community thrives through financial savings and improved efficiency,” says Steve Poniatowicz, senior vice president & chief operating officer of Marina Energy.

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?’”

Here Comes The Sun: India On Verge Of Becoming Global Solar Power

on December 12 2013 11:09 AM

India is on the brink of becoming a global solar power, according to a report just published by the World Bank. Under the government’s Jawaharlal Nehru National Solar Mission Phase-1 (JNNSM), which was initiated in January 2010 to promote sustainable growth, broadly expand solar power, and deal with the effects of climate change, India’s installed capacity of solar power has already jumped from about 30 megawatts to more than 2,000 MW.
The World Bank noted that JNNSM has also helped bring down the cost of solar power to competitive levels – down to about $0.12 per kilowatt-hour for solar photovoltaic, and to $0.21 per kWh for concentrated solar power, thereby making India one of the world’s lowest-cost destinations for grid-connected solar power. “In a short span of three years, India has made impressive strides in developing its abundant solar power potential,” said Onno Ruhl, World Bank Country Director in India, according to The Hindu newspaper. “With more than 300 million people without access to energy and industry citing energy shortage as key growth barrier in India, solar power has the potential to help the country address the shortage of power for economic growth.”
Indeed, the solar park in Charanka in Gujarat is already the largest such facility in all of Asia. Of equal importance, the bank said, expansion of solar power would reduce India’s over-dependence on imports of coal and diesel for power generation, cut greenhouse gas emissions and also upgrade the nation’s energy security. The bank report also highlighted two special features of India’s solar program – the bundling of solar power with unallocated thermal generation and the introduction of “reverse auctioning.” The “bundling” of solar power with cheaper forms of conventional energy sources had cut solar power tariffs for distribution centers. The “reverse auction” process has allowed qualified bidders to enjoy the benefits of falling global prices of solar components.
But the World Bank cautioned that India faces some challenges in meeting its stated target of adding 20,000 MW of solar capacity by 2022, noting that New Delhi “needs to address the key barriers and constraints that could come in the way of scaling up the solar program.” Ashish Khanna, an energy specialist and an author of the study, noted that “building on the success of Phase 1 [JNNSM], the program now needs to focus on promoting financing of solar projects by commercial banks, developing shared infrastructure facilities such as solar parks and identifying comparative advantage of Indian manufacturing across the supply chain.” The bank suggested that India develop and finance public infrastructure enterprises like solar parks in order to further cut costs and boost efficiencies.
Coincident with the release of the World Bank report, the Indian government said it will construct 60 “solar cities” across the vast country. The minister of new and renewable energy, Farooq Abdullah, said approval in principle has been reached with 55 cities, of which 45 have already been sanctioned. "Out of these 45 cities the master plans have been finalized for 36 cities," Abdullah said.
Among the many solar projects proliferating across the width and breadth of India, a Singaporean firm, Third Wave Power, which manufactures solar chargers, is expecting huge demand for its services in rural, undeveloped India. "We expect demand for portable solar [chargers] to reach a high of 40 million units in the next five years in rural India, including small towns," Third Wave's chief executive officer V.S. Hariharan said, according to Press Trust of India.
Hariharan said the market for its portable solar chargers probably would come from areas that are located far from the main electricity grids as well as from regions that suffer chronic shortages of electricity. Indeed, market surveys suggest that as many as 80,000 villages in India have no electricity. "We can charge these solar panels anywhere in the sun and then use it to recharge mobile phones and other light-power consuming instruments," Hariharan told PTI.

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.”

Battery Back Up For Solar

From The New York Times -

December 4, 2013

SolarCity to Use Batteries From Tesla for Energy Storage

Commercial building owners, even those who reduce their overall energy use, have long struggled to cut special power fees that are based on periods of highest demand.
Now, SolarCity, the fast-growing solar installer, says it has found a solution, in the form of a battery system created with Tesla Motors.
The system, to be announced on Thursday, includes batteries about the size of a small refrigerator and software that controls when a building’s operations run on power from the solar array, the battery or the grid.
Called DemandLogic, it could allow businesses to use stored electricity in times of highest demand, which would reduce their usage at peak periods and the associated fees, called demand charges.
“We are providing them a solution to reduce their energy cost and demand cost,” said Lyndon Rive, SolarCity’s chief executive, adding that the systems would provide backup power and a working solar array during blackouts. Although he said he did not see the systems as a step toward independence from the grid, storage would be important to maintaining grid stability as more customers adopt solar.
The product grew from a $1.8 million grant in 2010 from the California Public Utilities Commission to study the possibilities of storing electricity from rooftop solar arrays in batteries. The company has also signed up about 300 of its residential customers for a pilot program using battery packs from Tesla, whose chief executive, Elon Musk, is the chairman of SolarCity and Mr. Rive’s cousin.
The company will begin offering its storage systems in parts of California, Connecticut and Massachusetts. Although the combination of solar with storage could prove potent, said Sam Jaffe, a senior research analyst at Navigant Research, the market for it is by no means assured.
“It’s not a no-brainer — you still have to have the exact right combination of rates and demand charges and the cost of that equipment,” he said. He added, though, that if the systems are configured to take advantage of a 30 percent federal tax credit, the economics would have broader appeal.
The SolarCity systems, which are designed to be eligible for the credit, will be made available to new solar customers signing 10-year service agreements and are made to store about a third of the energy the solar array can produce. Mr. Rive said the company would guarantee the demand charge reductions, which he expects to run around 20 percent.
The demand charges, meant to compensate the utility for capital investments in distribution infrastructure, are based on so-called peak demand, or the highest amount of electricity used within the billing period. So even companies using less electricity overall can incur high fees. Part of the appeal for businesses trying to reduce their electric loads is that the system allows them to continue operating at full capacity, rather than reducing power usage, as in traditional demand response programs, Mr. Rive said.

Water Company Goes Solar

Utilizing off the shelf technology -

WSSC turns to solar power to cut sewage- treatment electricity costs

By , Published: December 21

On a recent gray December morning, nearly 8,500 solar panels covering 13 acres in Germantown tilted toward the sky, straining to harness any glimmer of sunlight.
Their host: a sewage-treatment plant in Montgomery County, one of the first in the Washington region to try solar power. The panels, also installed at a Washington Suburban Sanitary Commission facility in Upper Marlboro, began operating in October.
Solar panels are expected to provide up to one-fifth of the two plants’ electrical needs at rates 25 percent cheaper than traditional electricity, WSSC officials said. (And, yes, if it’s a cloudy day or the middle of the night, your toilet will still flush.)
“For a utility, it’s a huge milestone, because very few have solar power,” said Rob Taylor, the WSSC’s energy manager. “If we can show we can buy alternative energy cheaper than conventional energy, it’s a win-win situation.”
The idea is catching on with water and sewer utilities across the country, in part because they guzzle electricity. Operating round-the-clock, the facilities run enormous pumps to deliver drinking water and then use huge blowers, centrifuges and other equipment to treat sewage and return the disinfected water to local rivers. Those energy costs can fluctuate dramatically, putting pressure on operating budgets, utility officials say.
“We’re a massive energy user, and we pay a pretty penny for it,” said George S. Hawkins, DC Water’s general manager.
Sewage-treatment plants, in particular, are being looked at for solar power because vast parcels of land bought decades ago as buffers for nearby communities can accommodate acres of the panels. Meanwhile, the panels’ prices have dropped significantly in recent years, helping utilities achieve bigger savings.
Utility officials say they also are exploring ways to reduce their dependence on the electrical grid during and after severe storms, when power outages can wreak havoc on sewer systems and cause overflows into streams.
It’s also about saving money. DC Water, the largest consumer of electricity in the District, is installing equipment similar to a giant pressure cooker at its Blue Plains Advanced Wastewater Treatment Plant in Southwest Washington. The equipment will “cook” and sterilize the brown, goopy sludge collected from treated sewage and turn it into food for methane-generating bacteria. The methane gas will then be burned to power steam turbines that produce electricity, officials said.
DC Water officials said they expect the system to save the utility $10 million in electricity costs — and another $10 million in trucking costs because half as much sludge will need to be hauled away. The utility also is exploring selling the sterilized sludge as fertilizer, Hawkins said.
The annual savings are expected to more than cover the debt service on the $470 million borrowed for the project, Hawkins said. That will free up money needed to repair and replace aging infrastructure, such as underground pipes that burst after too much decay, he said.
Hawkins, the former head of the District’s Department of the Environment, said the new process also is expected to cut the treatment plant’s greenhouse gas emissions by one-third. “We’re very aware of the fact that a lot of the energy we’re using is coming from big Midwestern coal plants with quite a big environmental footprint,” Hawkins said.
Blue Plains has less open land available for solar panels than some other treatment plants, he said. Still, DC Water is considering putting panels on underground settling tanks and other structures on the 150-acre campus.
Howard County officials began looking at alternative energy sources last year, after Hurricane Sandy knocked out power to the Little Patuxent Water Reclamation Plant in Savage. The outage caused 19 million gallons of diluted but untreated sewage to flow into Little Patuxent River, officials said.
The county is installing three diesel-powered generators to provide backup power, along with a solar panel system to offset the diesel emissions and provide alternative power.
The solar panels are projected to save about $22,800 in annual electricity costs and offset the generators’ carbon dioxide emissions by 150 percent, Howard officials said.
“If we’re going to be able to expand our solar capacity, we have to creatively look at publicly owned infrastructure that has capacity” for solar equipment, Howard County Executive Ken Ulman (D) said. “Especially in urban areas, treatment plants are a big part of the solution.”
In Northern Virginia, Fairfax Water officials recently determined that it would take too long — 36 years — for the annual electricity savings to cover the costs of installing solar panels at a large drinking-water filtration plant, said Shawn O’Neill, the utility’s manager of energy programs.
However, he said Fairfax Water is considering solar-powered security cameras, outdoor lights and office building heating. O’Neill said solar power would be especially useful to automate remote valves that now must be operated manually in areas with no electricity.
The WSSC solar program is a public-private partnership. Washington Gas Energy Systems paid the $12 million to install the solar panels and will operate them for 20 years. The WSSC pays only for the solar power it uses. WSSC officials say they expect to save $3.5 million total in electricity costs over the 20 years and cut the two plants’ annual carbon dioxide emissions by 3,200 metric tons — described as the equivalent of taking 665 cars off the road.
Scott Wiater, president of Rockville-based Standard Solar, which installed the WSSC solar panels and will maintain them, said utilities are focused on those savings.
“They’re doing it for the bottom line. That’s the primary driver,” Wiater said. “The feel-good environmental aspects are just gravy for them.”

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."

The Battle To Control Solar Power

     A number of years ago when I told friends with solar power interests that I wanted my system to have batteries, some would question my sanity - you live in the city, connecting to the grid is easy, they would say. I tried to tell them that they were missing something - even though I live in the urban core, being capable of being powered completely from off the grid is a worthy goal with numerous advantages. The most basic is that allows one to be a true producer - relying on the grid at night should be seen as a back-up, not a first line strategy.
    In this article from Bloomberg, we are shown California electric utilities that are rejecting battery supported solar electric systems from grid inter-connections on technical reasons when more likely their objection is rooted in a non-ability to envision a different business model that includes micro users/producers. That smart meter is not so smart.


Battery-Stored Solar Power Sparks Backlash From Utilities

California’s three biggest utilities are sparring with their own customers about systems that store energy from the sun, opening another front in the battle that’s redefining the mission of electricity generators.
Edison International (EIX), PG&E Corp. and Sempra Energy (SRE) said they’re putting up hurdles to some battery backups wired to solar panels because they can’t be certain the power flowing back to the grid from the units is actually clean energy.
The dispute threatens the state’s $2 billion rooftop solar industry and indicates the depth of utilities’ concerns about consumers producing their own power. People with rooftop panels are already buying less electricity, and adding batteries takes them closer to the day they won’t need to buy from the local grid at all, said Ben Peters, a government affairs analyst at Mainstream Energy Corp., which installs solar systems.
“The utilities clearly see rooftop solar as the next threat,” Peters said from his office in Sunnyvale, California. “They’re trying to limit the growth.”
California is the largest of the 43 states encouraging renewables by requiring utilities to buy electricity from consumer solar installations, typically at the same price that customers pay for power from the grid. The policy, known as net metering, offers a way for households to reduce their bills. It underpinned a 78 percent surge in the state’s residential installations in the second quarter from a year earlier, according to the Solar Energy Industries Association.

Battery Costs

Solar systems with batteries attached have gained a foothold in the market as costs fall, allowing customers more flexibility for using their own power at night or when local supplies fail. The systems average about $12,000 to $16,000, adding about 25 percent to the cost of rooftop power plants, according to Outback Power Inc., an Arlington, Washington-based provider of battery-backed solar systems.
Matthew Sperling, a Santa Barbara, California, resident, installed eight panels and eight batteries at his home in April.
“We wanted to have an alternative in case of a blackout to keep the refrigerator running,” he said in an interview. Southern California Edison rejected his application to link the system to the grid even though city inspectors said “it was one of the nicest they’d ever seen,” he said.
“We’ve installed a $30,000 system and we can’t use it,” Sperling said.
Utilities say the storage systems open the possibility of fraud. The issue is whether all the electricity being sold through the net metering program is generated only by renewable sources, as required. Consumers in theory can fill the batteries with power from the grid and then send it back designated as renewable energy. With the solar-battery systems, there’s no way to determine the source of the energy. Solar suppliers say that’s not happening.

Storage Rules

Power-market regulations and the industry’s ability to monitor flows from solar systems haven’t kept pace with the technology, said Gary Stern, director of regulatory policy at Southern California Edison, a unit of Edison International.
“Our rules are not really caught up to effectively include issues with energy storage,” Stern said in a phone interview from Rosemead, California.
The company doesn’t want to “discourage solar” and is working with regulators to come up with “reasonable policies” for battery-storage systems, said Vanessa McGrady, a Southern California Edison spokeswoman.
State regulators are aware of the problem and are working on guidance to offer both solar installers and utilities, according to Terrie Prosper, a spokeswoman for the California Public Utilities Commission in San Francisco.

‘Some Complaints’

“There have been some complaints from developers in Southern California Edison’s territory that Edison has inconsistently applied the benefits of net energy metering to energy-storage projects,” Prosper said in an e-mail. The commission is working with all three utilities “to provide formal direction on these issues in the coming months.”
The utilities said they would approve systems that have panels and batteries if they had two meters to verify that only solar energy is sold to the grid. Such a configuration would boost installation costs by at least $1,300, according to Neal Reardon, the state utility regulator’s interim supervisor of customer generation.
The dispute is expanding as California promotes wider use of batteries. Regulators in June proposed that the top three utilities procure 1.3 gigawatts of storage capacity by 2020. The state has set a goal of obtaining 33 percent of its power from renewables by 2020, the nation’s strongest requirement. With more electricity coming from intermittent sources such as wind and sunlight, storage systems will be an important tool to manage the grid.

Falling Prices

Demand for the systems may grow as prices decline. Battery costs are forecast to fall 57 percent to $807 a kilowatt-hour in 2020 from $1,893 for a kilowatt-hour of storage capacity now, according to data compiled by Bloomberg. The global market for solar systems combined with energy storage will rise to $2.8 billion in 2018 from less than $200 million this year, according to Boston-based Lux Research Inc.
About 391 megawatts of solar panels were fitted at customer sites across the state last year, according the California Solar Initiative. The price to install residential projects has declined 15 percent to $3.71 a watt in the second quarter from $4.35 a year earlier according to the Washington-based trade group SEIA.
Battery systems are the latest innovation that’s unraveling the traditional monopoly utilities have enjoyed in supplying consumers with electricity. Two decades ago, federal regulators opened the system to independent power producers, eating away at the utility’s control of generation. The battery systems will put more customers out of reach.

Rejected Applications

“What we are seeing now as a fairly rare event may be more common by the end of the decade,” said Southern California Edison’s Stern.
Mainstream began hearing in May that Southern California Edison was rejecting some of its clients from the net metering program. As many as 60 projects with panels and batteries have been turned down by California utilities, the company estimated.
PG&E Corp. (PCG), the owner of California’s biggest utility, has also rejected standard net metering applications from customers with both panels and batteries, and referred them to another program that requires an interconnection fee.
“The key is that the full retail net energy metering credits and subsidies are only available to renewable facilities,” Lynsey Paulo, a PG&E spokeswoman, said in an e-mail.
San Diego Gas & Electric, a unit of Sempra Energy, said it hasn’t received any such applications, and it would deny them if it did. Sempra slipped less than 0.1 percent to $85.43 at the close in New York. PG&E climbed 1.5 percent and Edison gained 1.1 percent.

‘State of Flux’

“Technically, a customer who now has a combined system that includes both rooftop solar panels and battery storage, the battery storage may not qualify for net energy metering under current rules,” said Stephanie Donovan, a spokeswoman for San Diego Gas & Electric. “The rules are in a state of flux.”
Mainstream’s Peters said Southern California Edison is now rejecting systems that are identical to ones it had approved in the past. The developer had been installing two to three solar-storage projects a week in Southern California at the start of this year. That’s dropped to zero in recent weeks, and some orders have been canceled.
“Net metering is the lifeblood of solar in America,” Peters said. “That’s why this seemingly inconsequential issue is getting so much attention.”
Solar panel owners aren’t trying to “game the system,” said Adam Browning, executive director of the San Francisco-based lobbying group Vote Solar Initiative. “The next step is that people with solar and batteries will find a way to make it work without utilities.”

Solar Stock Update


April 6, 2013

Why Solar Power Stocks Are Still Earthbound

LONG-SUFFERING investors in solar energy stocks had reason to enjoy the first six weeks of 2013. After several years of poor performance while the overall market advanced, solar and other “green” energy technologies were market leaders early this year.
But by the end of the quarter, most of these stocks had fallen again. Was the strong performance of early this year simply a dead-cat bounce? What are the prospects for an emerging, relatively expensive technology that seeks to displace dirty — but cheap — hydrocarbons?
At the core of solar’s sorry market performance lies an enigma: solar sells, but it’s tough to turn a profit.
Global demand for clean, renewable energy is not the issue. “Demand has exceeded by far the projections of even two years ago,” Ben Schuman, an analyst at Pacific Crest Securities, said.
At the end of last year, installed global solar capacity stood at 96.4 gigawatts, up 43 percent from 2011 and roughly the equivalent capacity of 115 typical nuclear plants, according to Shayle Kann, vice president for research at GTM Research. Mr. Kann predicted further growth of 35 percent this year, to 129.7 gigawatts.
Nevertheless, company profits in the sector have been erratic — and shareholder profits scarce. The Guggenheim Solar exchange-traded fund, which mirrors a portfolio of solar stocks, fell nearly 30 percent in the 12 months through March.
So what is the most commonly invoked explanation for an industry where sizzling demand translates into sinking share prices? “Chinese industrial policy,” replied Kevin Landis, manager of the Firsthand Alternative Energy fund.
Chinese national and local governments have encouraged solar production with a grab bag of inducements, including loans, loan guarantees, tax breaks and even free land.
But the solar market, unlike other industries prone to cyclical overcapacity and subsequent busts, hasn’t self-corrected. Chinese vendors, Mr. Schuman said, haven’t been “as responsive to typical indicators” of excess production. “They haven’t closed capacity,” he said. “In China, shareholder profit can be a lower priority than employment, or the competitive dynamics between provinces and cities.”
So the prices of solar panels have been in free fall. In 2005, panels typically cost $3.50 per watt of power. By last year, prices had tumbled to 75 cents a watt. This year, Mr. Kann estimates, they will fall to 49 cents.
But Ken Abrams, a manager of the Vanguard Explorer fund for the last 18 years, says he thinks a looming shakeout of suppliers will ease overcapacity. Chinese producers are among the prime victims of their own overproduction, he said. And it is unclear how long the Chinese will support failing ventures. Eight Chinese banks pushed the main subsidiary of one major panel producer, Suntech Power Holdings, into bankruptcy last month.
“We see increasing hesitance on the part of Chinese government agencies to finance continuing deficits,” Mr. Abrams said. If Chinese authorities withhold support, more producers will fail, easing the overcapacity that has shredded prices.
Who would gain in such a shakeout? Mr. Abrams says it is a good time to consider industry leaders. The Vanguard fund holds large positions in First Solar, a solar systems developer based in Tempe, Ariz., and in Solar City, a leader in leasing solar systems; it is based in San Mateo, Calif.
But globally, low-cost producers should prevail, Mr. Schuman said. These would “probably be Asia-based,” he added.
Some fund managers are looking to a creative business model that can flourish with rock-bottom panel pricing.
Why lock into selling solar panels that keep getting cheaper? Better to buy the panels, install them free and then charge for the electricity they generate, gaining a predictable revenue stream. That’s the logic behind Solar City — which mainly serves residential and commercial customers in the United States — and several private solar leasing companies
“When the price of panels goes down, their business gets better,” Mr. Landis said. “The sweet spot is buying the panels and owning the output.”
Leasing is intended to overcome customer resistance to the high upfront cost of solar installation. Since a December initial public offering, Solar City shares have more than doubled.
Still, the leasing model requires upfront investment that can obliterate earnings until the customer base expands enough to produce offsetting lease income. Such is not yet the case with Solar City. which reported a larger-than-expected loss in the fourth quarter of last year.
Solar City is not the only company that employs leasing. SunPower, a major panel producer based in San Jose, Calif.,, has built a leasing business. And with several smaller private leasing firms, further I.P.O.’s are “a good possibility,” Mr. Abrams said.
“Leasing is going to be 90 percent of the solar business,” he said.
Colm O’Connor, co-manager of the Calvert Global Alternative Energy fund, says he expects the United States, Japan and China to lead this year in solar installation growth. Mr. O’Connor has a position in Kyocera, the ceramics maker and panel manufacturer, which could benefit from adoption of solar power in Japan.
In most areas, solar power is more expensive than coal and natural gas options for electricity generation. But the gap has narrowed, and in places like Hawaii, Italy and Japan, he says, solar is now roughly even in cost. He has trimmed his overall investment in solar, however, preferring other areas of alternative energy. His largest holding is Novozymes, the Denmark-based enzyme maker that stands to gain from the emergence of cellulosic ethanol, made from sources other than corn. Novozymes will capture “a large part” of the cellulosic market, he predicted. “We are favorable on the long-term outlook for cellulosic ethanol.”
Mr. O’Connor also favors companies that help manage delivery of energy from solar and wind sources. The Prysmian Group, based in Milan, Italy, has contracts to connect a North Sea wind park with the mainland grid in Germany. The PSI Group, based in Berlin, markets software that helps to manage the fluctuations in renewable energy production.
Frederick Reynolds, who manages the Reynolds Blue Chip Growth fund, has stakes in Solar City and First Solar. But, he says: “I don’t have much conviction in solar stocks in general at this time. I’m running the risk that I’m early.”
Mr. Reynolds tries to balance long-term optimism with near-term anxiety. “I think they can do well long term,” he said, “but until then there’s lots of volatility.”
ONE factor that may eventually help solar stocks is that institutional investors have relatively small holdings.
For example, they own slightly less than 22 percent of SunPower shares, according to Nasdaq. By contrast, institutions, which include pension funds, insurance companies and mutual funds, own more than 92 percent of Google’s outstanding shares.
Asked if low institutional ownership could turn into a positive, because so much buying power is untapped, Mr. Reynolds said: “I see it as a positive. A lot of institutions may be buying after me.”
Until then, holders of solar stocks can only nurse their wounds. Those who take the lead are often rewarded with arrows in their back. And right now, a lot of solar investors have “backs full of arrows,” Mr. Landis lamented.
