Large-Scale Solar Power Installations Gaining Ground -- and Roofs

Everywhere under the sun, from California to Florida and lots of other places, there appears to be growing interest in large-scale solar power installations in the United States, at least according to a number of announcements by utilities and vendors.

U.S. Department of Energy publication highlighted the trend recently. The article also cited big new projects in New Mexico, as well as significant but smaller efforts North Carolina and even in in less-sun-splashed places as Pennsylvania and New Jersey. Said the energy department's report:

"A spate of announced plans to build large solar power facilities throughout the United States seems to indicate that relatively large-scale systems are becoming commonplace. The trend is most apparent in concentrating solar power, with a number of facilities in the planning stages with capacities greater than 100 megawatts." 

Notable projects include a proposal to build a 106.8-megawatt concentrating solar facility in California. Concentrating solar refers to solar thermal technology that use mirrors to convert the sun's energy into heat that is used to then create steam to drive generating turbines.

In the California project, scheduled for completion in 2011, Pacific Gas and Electric Company has signed a contract for the power from the facility, according to a statement from the utility. The deal -- with San Joaquin Solar LLC (no website available), which traces its corporate parentage to Europe's Martifer Group -- will cover power produced from a combination of solar thermal and biofuel technologies. According to PG&E's statement:

"Martifer's renewable hybrid projects combine Luz solar thermal trough technology and steam turbines powered by biomass fuel to produce hybrid solar-biofuel renewable electricity. The incorporation of biofuel increases the overall production of renewable power by allowing for around-the-clock production of clean energy, even at night or when sunlight is not at its strongest."

The large amounts of raw material for the biofuel element of the project, located in the state's Central Valley, includes livestock manure and other agricultural wastes.

PG&E, along with its in-state counterpart Southern California Edison Company, were recently cited by an industry group as among the top utilities in the country for integrating solar power into their grids. PG&E also this year signed contracts for an estimated 900 megawatts of solar thermal power.

Edison is no slouch, either, having announced just in June that it was buying 245 megawatts of solar thermal power in the nation's first commercial effort using "power tower" technology. That move followed the company's launch of an initiative to install 250 megawatts of photovoltaic solar cells on roofs. The company already buys more than 90 percent of U.S. solar energy production. 

A lot of this has been reported by Climate Law Update, which has also covered projections that solar power could begin accounting for a significantly larger share of the nation's energy picture. Similarly, Climate Law has noted another project cited in the energy department dispatch, the announcement that the four largest utilities in New Mexico were soliciting proposals to build a concentrating solar plant in that state using parabolic solar troughs (like those pictured).

Although the energy department report gave no reasons for the trend, PG&E, for instance, cited California's renewables portfolio standards in its announcement of the Central Valley power purchase. Meanwhile, lawmakers in Congress could again try as early as this week to break the impasse over renewable energy tax credits that could help clarify the financial future for the projects, according to industry advocates. 

Other projects highlighted by the energy department included plans by Florida Power and Light Company, as described in an FPL press release and a statement from the Florida Public Service Commission, to build a variety of new solar generation facilities. They include photovoltaic projects on the utility's own land and at the Kennedy Space Center, as well as a larger solar thermal plant located an existing natural gas-fired generating plant.

Several projects employing photovoltaics -- the technology commonly used in rooftop installations -- are also going forward, as underscored by the Edison and FPL announcements. Other evidence of interest in the technology includes:

Just days ago, First Solar also announced it would build a 10-megawatt photovoltaic soar plant for Sempra Generation in Nevada. Sempra Generation also issued a statement on the project, which is located adjacent to an existing natural gas facility.

No Slowdown for Clean Tech Investments

Stocks might be sliding, oil is at a record high and the economy is in the doldrums, but venture capital investment in clean technology is showing no sign of slowdown, according to this story in today's San Francisco Chronicle. In fact, it is booming.

According to a recent report cited by the Chronicle, VC investment in clean tech hit $2 billion in the second quarter, up a whopping 60 percent from last year. Most of that investment was in solar thermal (pictured) and second-generation biofuels, which can create fuel from sources such as algae. And most of the money came from Silicon Valley. Where else?  

For those companies seeking capital, perhaps there is a home-field advantage at work. The largest chunk of cash -- 40 percent -- was distributed to California companies while U.S. companies attracted 74 percent of the total.

European companies attracted another 13 percent, mostly in the U.K. China came in third at 12 percent and India received just 0.6 percent.   

Government Hiatus on New Solar Applications Sparks Debate

A federal moratorium on accepting new applications for solar energy projects on areas managed by the U.S. Bureau of Land Management has sparked some controversy, it seems.

Those concerns have emerged as the BLM recently embarked on a series of public meetings on its actions, which include developing a new environmental impact statement with the U.S. Department of Energy to assess the effects of the developments, as Climate Law Update recently reported. The government previously had in hand about 125 applications for solar projects covering approximately a million acres of land in the West.

During the approximately 22-month process of developing the environmental document, the BLM said it wouldn't accept new applications for solar projects. That has upset some in the industry, according to reports that have begun emerging as the public meetings, which will help determine the scope of the environmental project, begin. Among the critics were representatives of Ausra, a California company that builds solar thermal facilities, and Acciona Energy, which operates a Nevada solar thermal plant.

Said Ausra's Sean Kiernan, according to a report in the Las Vegas Review-Journal:

"Freezing the industry will effectively stunt the industry and effectively destroy the industry before it gets off the ground."

No less a political heavyweight than Senate Majority Leader Harry Reid, a Nevada Democrat, has also balked at the government's hiatus. In a statement last week, as officials were holding one of the meetings in Las Vegas, Reid accused the BLM of sending "the wrong signal to solar power developers" and placing a "misplaced higher priority" on fossil fuels. He added he would look into the matter "to determine what can be done to accelerate solar power development without delay."

The Las Vegas Sun also carried a story citing a chorus of boos by solar companies, and noted that Nevada could be particularly affected by the government's actions because the BLM controls 67 percent of the state's land. The paper also reported that federal officials might have neglected to notify Reid of the moratorium.

A BLM official who is working on the program could not be reached for comment Monday. The agency has in the past described the project as a necessary first step in evaluating to what extent public lands can be used for renewal be energy projects. BLM officials recently expanded the agency's meeting schedule, in part to include more sessions in California, and they extended the deadline for comments by July 15. Officials have established a special web site devoted to the the process.

   

Of course, as Climate Law Update has noted in the past, some elements of solar and other renewable energy projects have created what could at least be characterized as ambivalence among conservationists and environmentalists. Some of that has come through in accounts of the meetings so far.

For instance, the Riverside Press-Enterprise reported that environmentalists asked government officials to make sure that they protect the plants, animals and wilderness areas that occupy the lands. The Review-Journal noted concerns about the amount of water used by solar thermal projects, as well as the large tracts of land required, as well as worries that developers might clear large areas and then abandon their projects.

Meanwhile, the moratorium did not appear to be the chief worry of the country's chief solar power booster, the Solar Energy Industries Association. Spokeswoman Monique Hanis told Climate Law Update Monday that the trade group was glad the government was looking at the issue. But for her organization, she said, the "bigger concern" is the future of the investment tax credit, a 30 percent break for solar property that has been caught up in a larger impasse in Congress over tax incentives for wind, solar and other renewable energy projects.

Hanis said about 4,500 megawatts' worth of solar projects are already in the pipeline -- ahead of any that might be affected by the application moratorium. All, she said, could be affected:

"Even the ones that are already into the permitting stages won't get built because of the financials."

All of this is happening at a time when there's evidence that solar could soon reach a point where it's competitive in cost with traditional sources of electricity, and is poised to become a much bigger player in the nation's energy game.
