As reported By Christopher Martin Bloomberg News 3/21/12

NEW YORK – U.S. solar developers are luring cash at record rates from investors ranging from Warren Buffett to Google and KKR by offering returns on projects four times those available for Treasury securities.

Buffett’s Berkshire Hathaway Inc., together with the biggest Internet search company, private equity companies, and insurers MetLife Inc. and John Hancock Life Insurance Co., poured more than $500 million into renewable energy in the last year. That’s the most ever for companies outside the club of banks and specialist lenders that traditionally back solar energy, according to Bloomberg New Energy Finance data.

Once so risky that only government backing could draw private capital, solar projects now are making returns of about 15 percent, according to Stanford University’s Center for Energy Policy and Finance. That has attracted a wider community of investors eager to cash in on earnings stronger than those for infrastructure projects such as toll roads and pipelines. “A solar power project with a long-term sales agreement could be viewed as a machine that generates revenue,” said Marty Klepper, an attorney at Skadden Arps Slate Meagher & Flom, which helped arrange a solar deal for Buffett. “It’s an attractive investment for any firm, not just those in energy.”

With 30-year Treasuries yielding about 3.4 percent, investors are seeking safe places to park their money for years at a higher return. Solar energy fits the bill, with predictable cash flows guaranteed by contract for two decades or more. Those deals may be even more lucrative because many were signed before the cost of solar panels plunged 50 percent last year.

Buffett’s MidAmerican Energy Holdings Co. agreed to buy the Topaz Solar Farm in California from First Solar Inc. on Dec. 7. The project’s development budget is estimated at $2.4 billion and it may generate a 16.3 percent return on investment by selling power to PG&E Corp. at about $150 a megawatt-hour through a 25-year contract, according to New Energy Finance calculations. It will have 550 megawatts of capacity and is expected to go into operation in 2015, making it one of the world’s biggest photovoltaic plants.

“After tax, you’re looking at returns in the 10 percent to 15 percent range” for solar projects, said Dan Reicher, executive director of the Stanford center. “The beauty of solar is, once you make the capital investment, you’ve got free fuel and very low operating costs.”

The long-term nature of solar power purchase deals makes them similar to some bonds. And because a solar farm is a tangible asset, these investments also function much like those for infrastructure projects, with cash flows comparable to toll roads, bridges and pipelines, said Stefan Heck, a director at McKinsey & Co. in New York who leads the firm’s clean-tech work. Once a project starts producing power, investors can earn a return that’s “higher than most bonds,” he said. “There are a lot of pension funds with long-term horizons that are very interested in this space.”

Governments remain the biggest backers of the solar industry; President Obama’s administration suffered criticism for investing in Solyndra, a solar manufacturer that went bankrupt last year. Worldwide, the U.S. Treasury’s Federal Financing Bank was the biggest asset-finance lender for renewable energy companies in the past year, arranging 12 deals worth $11.2 billion, according to New Energy Finance. The Brazilian development bank BNDES, Bank of America, and Banco Santander followed.

In 2009, solar technology was so unfamiliar that few banks would back projects that required billions in upfront investment and wouldn’t begin producing revenue for years, Klepper said. The biggest financiers for the industry that year were Madrid- based Santander, HSH Nordbank of Hamburg and Banco Bilbao Vizcaya Argentaria of Bilbao, Spain, New Energy Finance said.

That year, the Energy Department began funding a program to guarantee loans for solar farms and other renewable energy projects that supported almost $35 billion in financing before winding down in September. The government’s endorsement assuaged investors’ concerns and built up a bigger community of people who understand how to make money from solar deals, said Arno Harris, chief executive officer of Sharp Corp.’s renewable power development unit Recurrent Energy.

“Solar is now bankable,” Harris said. “When solar was perceived as more risky, it required a premium,” and now it’s “becoming part of a much broader capital market.”

Long-term power-purchase contracts are the key to making solar a reliable investment, Harris said. Utilities in sunny states such as California, Arizona, and Nevada have agreed to pay premiums for electricity generated by sunshine.

Solar makes sense

May 31, 2011

As reported in Philadelphia Inquire May 30, 2011
With Pennsylvania
boasting the nation’s second largest number of solar-industry jobs, state
officials would be foolish to let the sun set on such a nascent but promising
industry. But that could happen due to a temporary mismatch between solar-energy
financing and market demand.

The construction of more than 4,000 solar projects has been a roaring
success, responsible for generating several thousand jobs at 600 solar
businesses. Growing that industry from scratch, with state and federal aid, also
boosted the use of nonpolluting and renewable energy. That will be particularly
helpful in meeting summer’s peak demand.

Yet, the boom in solar projects has outpaced the amount of solar energy
utilities are required to buy under the state’s alternative-energy rules. That
has depressed the value of solar-energy credits needed to provide a return on
photovoltaic solar systems, which have a steep, up-front price tag.

The best way for state officials to spur solar to new heights would be to
boost the modest solar-energy standard – now far lower than neighboring states,
at only 0.5 percent – by 2021. But last year, that idea ran into strong
opposition from Exelon and other utilities, coal producers, and business groups
– and a certain Republican candidate for governor.

Fortunately, a fellow Republican, State Rep. Chris Ross from Chester County,
unveiled a legislative proposal Tuesday that should be more to Gov. Corbett’s
liking. Ross would accelerate the amount of solar energy utilities are required
to purchase for the next few years, but leave the overall standard at just 0.5
percent. He would also follow other states by barring out-of-state solar
producers contributing to the solar glut in Pennsylvania.

The Ross proposal amounts to a tweak, but one that could be critical to
maintaining the state’s foothold in solar energy. Corbett and Republican
legislative leaders could fall back on tea-party ideological antagonism toward
so-called government mandates – or they could prove themselves progressive
enough to embrace a modest plan that makes sense for the state’s 21st-century
economy.

The California-based solar leasing firm Sungevity announced a deal on Monday with home improvement giant Lowe’s that could make obtaining a personalized estimate for installing solar panels a push-button affair at Lowe’s outlets.

The deal gives Lowe’s just under a 20 percent stake in Sungevity, according to a solar industry source, though neither company would discuss specific dollar figures.

Under the agreement, scheduled to launch in 30 Lowe’s stores in California in July, customers will be able to access kiosks equipped with Sugevity’s iQuote system, a Web-based application that allows homeowners to simply enter their address and receive a firm installation estimate within 24 hours, eliminating the expense of an on-site visit.

The system combines aerial and satellite image analysis with research by Sungevity engineers at the company’s Oakland headquarters to assess the geometry of a home’s rooftop, its disposition to the sun at different times of day and year and any potential occlusions presented by nearby vegetation or built objects.

In addition to an installation estimate, customers can also get a visual rendering of their home with solar panels installed. And if interested parties provide information on typical power usage, such as an account number or past electric bills, the iQuote system can estimate potential savings expected from using the equipment.

The iQuote system can already be used online, and the company’s founder, Danny Kennedy, estimated that roughly 25,000 users had taken it for a test drive, though only about 1,500 of those had been converted to sales.

The deal with Lowe’s, Kennedy said, could help Sungevity — a petite player in the solar leasing market compared to bigger players like SolarCity of San Mateo, Calif., or San Francisco-based SunRun, which raised $200 million in financing earlier this month — significantly expand its reach.

“This will help us to get in front of thousands more customers, in front of middle America,” Kennedy told The Huffington Post. “We’ll be taking it to the ‘burbs, as it were.”

Despite tough economic times and often uncertain economic incentives, a number of analyses predict a boom year for solar power in 2011.

A report published in December by IDC Energy Insights, a market research firm based in Framingham, Mass., estimated following a healthy 2010, the solar market in North America could well see two gigawatts of solar power installations this year.

Jay Holman, the report’s lead analyst, told The Huffington Post that those numbers had been revised somewhat, but that 2011 was still expected to bring in 1.6 gigawatts of new solar installations, roughly double the 2010 total.

Part of the reason for America’s interest in solar energy may be a decline in the robust incentives the once drew a deluge of equipment and installations to the European market, particularly countries like Germany, the Czech Republic and Italy, Holman said. Those countries have begun to scale back their subsidies, forcing companies to look to other markets.

Meanwhile, federal tax incentives, including a 30 percent tax cash grant extended through the end of 2011, have helped keep solar alive. Several states have healthy incentives in place as well, including the eight states where the Sungevity/Lowes deal will eventually be rolled out: Arizona, California, Colorado, Delaware, Maryland, Massachusetts, New Jersey and New York.

Holman also said solar leasing companies like Sungevity, SunRun and Solar City, which retain ownership of the equipment while reducing or, in many cases, eliminating the up-front installation costs, also help drive the expansion of solar power.

“Obviously, we’re obsessed with being customer-focused,” said Kennedy. “We hope that this deal will make going solar as easy as shopping for light bulbs.”

Shale gas refers to natural gas that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas. Over the past decade, the combination of horizontal drilling and hydraulic fracturing has allowed access to large volumes of shale gas that were previously uneconomical to produce. The production of natural gas from shale formations has rejuvenated the natural gas industry in the United States.

Did You Know?

Sedimentary rocks are rocks formed by the accumulation of sediments at the Earth’s surface and within bodies of water. Common sedimentary rocks include sandstone, limestone, and shale.

U.S. Natural Gas Supply, 1990-2035
Chart showing U.S. natural gas supply, 1990-2035. Source, EIA Annual Energy Outlook 2010

Did You Know?

Shale gas in 2009 made up 14% of total U.S. natural gas supply. Production of shale gas is expected to continue to increase, and constitute 45% of U.S. total natural gas supply in 2035, as projected in the EIA Annual Energy Outlook 2011.

Does the U.S. Have Abundant Shale Gas Resources?

Of the natural gas consumed in the United States in 2009, 87% was produced domestically; thus, the supply of natural gas is not as dependent on foreign producers as is the supply of crude oil, and the delivery system is less subject to interruption. The availability of large quantities of shale gas will further allow the United States to consume a predominantly domestic supply of gas.

According to the EIA Annual Energy Outlook 2011, the United States possesses 2,552 trillion cubic feet (Tcf) of potential natural gas resources. Natural gas from shale resources, considered uneconomical just a few years ago, accounts for 827 Tcf of this resource estimate, more than double the estimate published last year. At the 2009 rate of U.S. consumption (about 22.8 Tcf per year), 2,552 Tcf of natural gas is enough to supply approximately 110 years of use. Shale gas resource and production estimates increased significantly between the 2010 and 2011 Outlook reports and are likely to increase further in the future.

Where is Shale Gas Found?

Shale gas is found in shale “plays,” which are shale formations containing significant accumulations of natural gas and which share similar geologic and geographic properties. A decade of production has come from the Barnett Shale play in Texas. Experience and information gained from developing the Barnett Shale have improved the efficiency of shale gas development around the country. Another important play is the Marcellus Shale in the eastern United States. Surveyors and geologists identify suitable well locations in areas with potential for economical gas production by using both surface-level observation techniques and computer-generated maps of the subsurface.

Map of Shale Gas Plays for the Lower 48 States

How is Shale Gas Produced?

Two major drilling techniques are used to produce shale gas. Horizontal drilling is used to provide greater access to the gas trapped deep in the producing formation. First, a vertical well is drilled to the targeted rock formation. At the desired depth, the drill bit is turned to bore a well that stretches through the reservoir horizontally, exposing the well to more of the producing shale.

Hydraulic fracturing (commonly called “fracking” or “hydrofracking”) is a technique in which water, chemicals, and sand are pumped into the well to unlock the hydrocarbons trapped in shale formations by opening cracks (fractures) in the rock and allowing natural gas to flow from the shale into the well. When used in conjunction with horizontal drilling, hydraulic fracturing enables gas producers to extract shale gas at reasonable cost. Without these techniques, natural gas does not flow to the well rapidly, and commercial quantities cannot be produced from shale.

Schematic Geology of Natural Gas Resources

How is Shale Gas Production Different from Conventional Gas Production?

Conventional gas reservoirs are created when natural gas migrates toward the Earth’s surface from an organic-rich source formation into highly permeable reservoir rock, where it is trapped by an overlying layer of impermeable rock. In contrast, shale gas resources form within the organic-rich shale source rock. The low permeability of the shale greatly inhibits the gas from migrating to more permeable reservoir rocks. Without horizontal drilling and hydraulic fracturing, shale gas production would not be economically feasible because the natural gas would not flow from the formation at high enough rates to justify the cost of drilling.

What Are the Environmental Issues Associated with Shale Gas?

Natural gas is cleaner-burning than coal or oil. The combustion of natural gas emits significantly lower levels of key pollutants, including carbon dioxide (CO2), nitrogen oxides, and sulfur dioxide, than does the combustion of coal or oil. When used in efficient combined-cycle power plants, natural gas combustion can emit less than half as much CO2 as coal combustion, per unit of energy released.

However, there are some potential environmental issues that are also associated with the production of shale gas. Shale gas drilling has significant water supply issues. The drilling and fracturing of wells requires large amounts of water. In some areas of the country, significant use of water for shale gas production may affect the availability of water for other uses, and can affect aquatic habitats.

Drilling and fracturing also produce large amounts of wastewater, which may contain dissolved chemicals and other contaminants that require treatment before disposal or reuse. Because of the quantities of water used, and the complexities inherent in treating some of the chemicals used, wastewater treatment and disposal is an important and challenging issue. If mismanaged, the hydraulic fracturing fluid can be released by spills, leaks, or various other exposure pathways. The use of potentially hazardous chemicals in the fracturing fluid means that any release of this fluid can result in the contamination of surrounding areas, including sources of drinking water, and can negatively impact natural habitats.

SOUTH PHILADELPHIA – November 18, 2010 (WPVI) — When you think of the Eagles you think GREEN – and we’re not just talking about the

The Eagles organization has long been committed to the environment and energy sustainability. Well, today the Eagles will take a bold move when they make Lincoln Financial Field the first major sports stadium in the world to generate its own electricity.

In the coming months the Linc will be outfitted with approximately eighty 20-foot tall spiral shaped wind turbines on the top rim of the stadium and 2,500 solar panels on the façade. Along with the state of the art power system, energy will be generated on-site.

The project will cost an estimated $30-million, but the Eagles expect to save an estimated $60-million in energy costs in the coming years.

The stadium will generate enough electricity to power 26,000 homes – far more than needed to power the stadium. So, the Eagles will be selling excess electricity back to the local power grid.

Two hundred people are expected to be employed to design and install the system. Six hundred more jobs are expected to be created because the Eagles are committed to using people from the local community through contractors and vendors.

More information on the project is scheduled to be released later today at Lincoln Financial Field by Eagles owner Jeffrey Lurie, Philadelphia Mayor Michael Nutter and NFL Commissioner Roger Goodell.

The Garden State’s status as a solar-energy leader will get a major boost Wednesday, when officials break ground on what will be the largest solar energy farm in the Northeast.

Con Edison Development, a subsidiary of Consolidated Edison Inc., and Texas-based Panda Power Funds plan to build a 20-megawatt solar farm on a 100-acre site in Pilesgrove. The installation, expected to go online in May 2011, will feature 71,400 solar panels and cost between $85 million and $90 million.

Con Edison Development and Panda announced their intent to partner on solar projects in April.

Steve Tessum, vice president of east region management at Panda and manager of the Pilesgrove project, said South Jersey was chosen as the site in part because of the state’s support of solar energy.

“We did look at other states,” Tessum said. “Quite frankly, the regulatory climate in New Jersey is friendly to somebody who wants to own and develop a solar-power utility.”

The farm will be connected directly to the electrical grid via the Atlantic City Electric distribution system, said Mark Noyes, vice president of Con Edison Development.

Noyes said the arrangement with Panda is a 50-50 partnership: Panda is taking the lead in development, Con Edison will take the lead in operations and energy management, and construction will be split.

“The reason it makes sense to partner with Panda is, much like our background, they’re developers and they know how to develop projects, whether natural gas and oil, wind, solar,” Noyes said. “The development expertise is really what drives the development.”

Noyes said the property had originally been slated for the development of 67 homes, each with its own septic tank.

“The town opposed that type of taxing, from an environmental and economic standpoint,” Noyes said. “The construction of those homes never got through the planning board, so we were able to go in and acquire that land from the local player for this solar farm.”

Tessum said the solar farm doesn’t require any municipal infrastructure development, as the housing plot would have.

Con Edison Development said the installation is expected to generate enough electricity to power 5,100 homes.

Solar Battle Heats Up

September 21, 2010

New Jersey has set aggressive goals for its solar industry. The question now is can it afford to meet them.
By Tom Johnson, August 31 in Energy & Environment |6 Comments

By most accounts New Jersey’s solar industry has enjoyed a remarkable run in recent years, installing up to 180 megawatts of capacity, enough to vault it at one point to behind only California in the number of solar installations.

Utility-Run Solar Energy Program Yields Disappointing Results

Clean energy advocates credit the solar industry with creating more than 2,000 jobs, a number expected to climb to 3,500 by the end of the year. And the more than 200 firms involved in the industry boost their argument that a green economy can only bolster New Jersey’s prospects for growth.

Yet the industry is facing tough questions from the Christie administration. The concern is cost: How expensive will it be to meet aggressive goals to increase New Jersey’s reliance on solar energy, a situation some argue is driving up the price of electric power in a state that already has high energy expenditures.

The Solar Balancing Act

The focus on solar occurs as the state Board of Public Utilities is trying to pinpoint ways to reduce utility bills while complying with legislation that increases solar energy goals dramatically.

By 2026, a bill passed this past January directs the state to have solar capacity of 5,000 megawatts, roughly equivalent to the output of five nuclear power plants. At the same time, funding for clean energy programs is being sharply curtailed and the agency is rethinking the state’s energy master plan and its ambitious goals for renewable energy.

What is worrisome to skeptics is the cost of solar energy today is still much higher than conventional energy. They note that solar renewable energy certificates on the spot market sell for around $670, or the equivalent of 60 cents per kilowatt hour. (Solar certificates are the price owners of solar systems earn for electricity they generate.) In comparison, consumers pay about 11 cents per kilowatt hour for electricity generated by conventional power plants.

Supply and Demand

Many solar advocates are frustrated because the debate is losing sight of the benefits the sector has delivered to New Jersey. They concede the price for the solar certificates is too high, but argue it is a function of demand outstripping supply and insist prices will drop when supply and demand are more in balance.

“There’s been not enough credit to the local solar industry that has developed,’’ said Fred Zalcman, director of regulatory affairs in eastern states for SunEdison, a large solar firm. “It’s created a lot of local jobs.’’

Others are blunter. “We believe solar is falling out of favor with this administration,’’ said Dolores Phillips, executive director of the Mid-Atlantic Solar Energy Industries Association, noting only $3.2 million is allocated to the solar residential program in a straw budget proposal for next year. “Too many discussions are taking place behind closed doors.’’

Developing Solar Responsibly

To some, though, the debate is timely. If New Jersey is going to pursue aggressive solar targets, then it must do it responsibly and must do it recognizing what the impact will be on ratepayers, argued Steven Goldenberg, an attorney who represents manufacturers that use tremendous amounts of energy.

Terry Sobolewski, business development manager for SunPower, said the industry needs to make its case how the rapid development of the sector in New Jersey has created thousands of well-paying jobs here, and would continue to do so if the state stays on target to promote solar aggressively.

“Now, we’ve got 180 megawatts of installed solar and it’s created 3,500 jobs,’’ said Sobolewski, who suggested an even bigger bonanza of new jobs could be created if the state sticks with its target of 5,000 megawatts by 2026. “If you project forward, it’s a lot no matter how you slice it.’’

Lower Prices Expected

For those who argue solar is too expensive based on the spot prices being fetched by the solar certificates, Sobolewski said that argument assumes that is the price being paid for all certificates when it reflects about two-thirds of the market. Other solar certificates, which are earned under long-term contracts signed with suppliers, are averaging about $374, he said. “With more long-term contracts, the price will come down.’’

He and others argue the price of solar systems also will drop as technology improves. And as larger solar systems are built, economies of scale will drive the cost down further.

“Yes, solar is expensive right now, but we’re building an industry,’’ said Matt Elliott, clean energy advocate for Environment New Jersey. “It’s nothing new to subsidize a new energy source so long as the costs keep going down and the technology is improving.’’

Beyond the issue of the solar certificates, advocates argue when trying to assess the cost of various programs, the state ought to consider the benefits. For instance, solar power replaces electricity generated by peaking plants, which are the most expensive ways of producing power and increase the cost of electricity for everyone. Solar produces the most power on days when peak plants generally run, typically, the hottest summer days when the sun is shining.

Solar Impulse, piloted by André Borschberg, flew for 26 hours and reached a height of 28,543 feet, setting a record for the longest and highest flight ever made by a solar plane.
By ALAN COWELL
Published: July 8, 2010

PARIS — Slender as a stick insect, a solar-powered experimental airplane with a huge wingspan completed its first test flight of more than 24 hours on Thursday, powered overnight by energy collected from the sun during a day aloft over Switzerland.

The organizers said the flight was the longest and highest by a piloted solar-powered craft, reaching an altitude of just over 28,000 feet above sea level at an average speed of 23 knots, or about 26 miles per hour.

The plane, Solar Impulse, landed where it had taken off 26 hours and 9 minutes earlier, at Payerne, 30 miles southwest of the capital, Bern, after gliding and looping over the Jura Mountains, its 12,000 solar panels absorbing energy to keep its batteries charged when the sun went down.

The pilot, André Borschberg, 57, a former Swiss Air Force fighter pilot, flew the plane from a cramped, single-seat cockpit, buffeted by low-level turbulence after takeoff and chilled by low temperatures overnight.

“I’ve been a pilot for 40 years now, but this flight has been the most incredible one of my flying career,” Mr. Borschberg said as he landed, according to a statement from the organizers of the project. “Just sitting there and watching the battery charge level rise and rise, thanks to the sun.” He added that he had flown the entire trip without using any fuel or causing pollution. The project’s co-founder, Dr. Bertrand Piccard, who achieved fame by completing the first nonstop, round-the-world flight by hot air balloon in 1999, embraced the pilot after he landed the plane to the cheers of hundreds of supporters.

“When you took off, it was another era,” The Associated Press quoted Dr. Piccard as saying. “You land in a new era where people understand that with renewable energy you can do impossible things.”

The project’s designers had set out to prove that — theoretically at least — the plane, with its airliner-size, 208-foot wingspan, could stay aloft indefinitely, recharging batteries during the day and using the stored power overnight. “We are on the verge of the perpetual flight,” Dr. Piccard said.

The project’s founders say their ambition is for one of their craft to fly around the world using solar power. The propeller-driven Solar Impulse, made of carbon fiber, is powered by four small electric motors and weighs around 3,500 pounds. During its 26-hour flight, the plane reached a maximum speed of 68 knots, or 78 miles per hour, the organizers said.

The seven-year-old project is not intended to replace jet transportation — or its comforts.

Just 17 hours after takeoff, a blog on the project’s Web site reported, “André says he’s feeling great up there.”

It continued: “His only complaints involve little things like a slightly sore back as well as a 10-hour period during which it was minus 20 degrees Celsius in the cockpit.”

That made his drinking water system freeze, the post said and, worst of all, caused his iPod batteries to die.

As reported by EIA’s Energy in Brief

Worldwide wind power generation exceeded 200 billion kilowatthours in 2008, which is equivalent to the annual electricity consumption of over 18 million average households in the United States. Wind generation increased by about 25% from 2007 to 2008, and has more than tripled since 2003. This growth is mostly due to capacity increases in the United States, China, India, and Western Europe. Despite this growth, the world still generated less than 1% of its total electricity from wind power in 2008.

Did You Know?

A feed-in tariff is a financial incentive that encourages the adoption of renewable electricity. Under a feed-in tariff, government legislation requires electric utilities to purchase renewable electricity at a higher price than the wholesale price. This incentive allows the renewable generator to achieve a positive return on its investment despite the higher costs associated with these resources.

Did You Know?

Because the wind does not blow 24 hours a day and because the timing of it cannot be controlled, electricity from wind is not available on demand. Although wind makes up a significant portion of Denmark’s generation capacity, the intermittent nature of wind has been mitigated by the connection of the Danish electrical grid to the grids of Germany, Sweden, and Norway. These interconnections allow Denmark to export electricity when wind power generation exceeds demand and import electricity when there is not enough wind.

The United States Generated the Most Wind Electricity in 2008

Overtaking the previous leader Germany, the United States led all other countries in wind power generation in 2008. The remaining top-ten wind power generators, listed in descending order, were Spain, India, China, the United Kingdom, Denmark, Italy, Portugal, and France. Although about 60 countries reported significant wind power generation in 2008, these top-ten countries accounted for more than 85% of all wind generation worldwide. Wind generation in China has grown an average of 70% annually since 2003, in spite of delays in bringing some of its new capacity online.

Denmark Generates the Highest Percentage of its Electricity Supply from Wind

Nearly 20% of Denmark’s electricity generation came from wind in 2008. The next highest levels of wind penetration are found in Portugal at 13%, Spain at 10%, Ireland at 9%, and Germany at 7%. No other country surpassed 5% penetration, including the United States, which generated over 1% of its electricity from wind in 2008.

Less than 2% of Global Wind Capacity is Offshore

According to the World and European Wind Energy Associations, installed global wind capacity reached 159,000 megawatts by the end of 2009, with only about 2,000 MW of that total located offshore. Offshore development lags behind onshore generally due to higher costs and technology constraints. Western Europe is home to nearly all existing offshore capacity — although prototype turbines for China’s first offshore farm were connected to the grid in 2009. As of June 2010, there are no operating offshore wind farms in the United States, although the 420-megawatt Cape Wind offshore project off the Massachusetts coast had secured local, State, and Federal approval as of April 2010.

Wind Power Generation is Expected to Continue Growing

Over the lifetime of the plant, electricity from wind power generally costs more than electricity from power plants burning fossil fuels.1 However, wind power is expected to continue to grow worldwide because of favorable government policies. Multiple types of government support exist, including a production tax credit and State renewable electricity portfolio standards in the United States, a feed-in tariff (see the “Did You Know” box on the left) in Germany, and wind capacity targets in China. According to EIA’s International Energy Outlook 2010, wind generation is expected to account for more than 3% of total world electricity by 2020.

It’s a bird, it’s a plane — it’s a solar panel?
Residents of many local towns may have recently noticed panels being installed about 15 feet up on residential utility and street-light poles. The panels are five feet by two and half feet, and weigh about 60 pounds. By the end of 2013, 200,000 panels will have been installed throughout New Jersey.

PSE&G sources say that their “investment is the largest pole-attached solar installation in the world … New Jersey has more installed solar capacity than any state except California.” New Jersey estimates its solar power capacity at 40 megawatts of “pole-mounted solar.” Karen Johnson, media spokesperson for the company, estimates one megawatt as enough energy to power approximately 800 homes.
The work is part of a renewable energy program approved for PSE&G by federal regulators last July. It is called Solar 4 All, and is estimated to be a $515 million investment on the part of PSE&G in New Jersey over the next three years. The goal of the program is to move the state closer to meeting an energy master plan requirement of 4.4% (or 80 megawatts) of solar energy use in the electric grid by 2020.
PSE&G says, “The installations will be paid for by PSE&G electric customers. The first year bill impact for the average residential customer will be roughly 10 cents a month.”
Currently, panels are being placed on pre-selected PSE&G-owned utility and street light poles only. Negotiations to share space with Verizon-owned poles are planned.
According to the PSE&G fact sheet on the installation (available at http://www.PSEG.com), poles that qualify for the panel meet several criteria, besides being owned by the utility company. PSE&G is selecting poles that can support the units, face in a southerly direction and have no more than one transformer already on the pole.
The Retrospect caught up with two contracted installers from Riggs Distler and Company, Inc. this week, while they installed a new panel on a pole on Haddon Avenue. Derwin Booker said that the project is keeping his union, and the contractor he works for, busy. While he has been working on installs in Collingswood and Haddon Township, he also worked on the recent installs along Kings Highway in Cherry Hill.
All of the panels are equipped with GPS (Global Positioning Satellite receivers), and each faces exactly 193 degrees south-southwest in order to maximize solar power collection, explained Booker. He said that specific poles were selected from the millions of utility and street poles throughout New Jersey. The panels are equipped with what he called an aggregator, which communicates the collection rates of 10 to 15 panels at a time, back to a main data collection site, so that the rate of energy per cluster of panels can be measured and tracked.
All of the solar energy collected by the panels flows back into the electronic grid as power. Booker commented that the additional energy generated can help in heavy electrical use periods – like summertime, when air conditioners are running — when service is at risk of brown-outs.
Additionally, PSE&G explains, “The installations will generate Solar Renewable Energy Certificates (SRECs). PSE&G will sell any SRECs it generates to offset program costs. PSE&G will sell the power into the PJM (Pennsylvania-Jersey-Maryland) wholesale grid and will receive federal tax credits – which will also be used to offset the cost to customers.”
