Top 10 solar utilities

A solar industry trade group on Thursday released its list of the Top 10 solar integrated utilities of 2008 and it will come as no surprise that California’s Big Three utilities took the top three spots.

What is news, and a sign that solar’s reach is extending beyond the Golden State, is that six of the Top 10 solar utilities on the Solar Electric Power Association’s list hail from places like New York and New Jersey.

Still, San Francisco-based PG&E (PCG), which claimed the No. 1 slot, alone connected 84.9 megawatts of photovoltaic solar to the grid in 2008, accounting for 44% of all new solar capacity last year. Southern California Edison (EIX) came in second with 32.4 megawatts and San Diego Gas & Electric (SRE) took third place with 16 megawatts.

Xcel Energy (XEL) in Colorado was close behind with 14.2 megawatts. After that the numbers take a dive to the single megawatts. Still, utilities from not-so-sunny places like Portland, Ore.  made the list.

Southern California Edison is No. 1 when it comes to total installed solar to date — 441.4 megawatts — due largely to the 354 megawatts of electricity generated by nine solar thermal power plants built in the 1980s that continue to operate in the Mojave Desert. PG&E came in second with 229.5 megawatts connected to the grid so far.

Those numbers should skyrocket in the coming years as the California utilities have signed contracts for more than 3 gigawatts of electricity to be produced by large solar farms. Utilities like Arizona Public Service (PNW) — No. 5 on the list for 2008 — are also beginning to contract for solar electricity to be produced by massive megawatt solar power plants.

California utility PG&E on Wednesday expanded an agreement with BrightSource Energy to buy 1,310 megawatts of carbon-free electricity to be generated by seven giant solar power plant projects – the world’s biggest solar deal to date. Coming on top of a 1,300 megawatt agreement with Southern California Edison in February, the Google-backed, Oakland, Calif.-based  startup says it now holds more than 40% of the Big Solar contracts in the United States.

PG&E had previously signed a power purchase agreement with BrightSource in April 2008 for 500 megawatts with an option to buy another 400 megawatts. The new 1,310-megawatt deal will supply enough electricity to power about 530,000 homes in California.

Those are impressive numbers, but not an electron of electricity has been produced yet. BrightSource now faces the challenge of licensing, financing billions of dollars in construction costs and then building nearly a dozen large-scale solar power plants to meet a 2016 deadline for the Southern California Edison (EIX) contract and a 2017 completion date for PG&E (PCG).  (The big wild card is whether transmission lines will be available to connect the power plants to the grid.) The first PG&E project is set to go online in 2012 with the first SoCal Edison solar farm to begin generating electricity the next year. Those first two power plants are part of a 400-megawatt complex BrightSource is planning for the Ivanpah Valley on the California-Nevada border.

“The biggest part of our strategy is to ramp up slowly and methodically,” BrightSource CEO John Woolard told Green Wombat. “We’re very, very careful about how we sequence the projects.”

To give you an idea of how arduous the licensing process is in California, consider that BrightSource filed its application to build Ivanpah with the California Energy Commission on Aug. 31, 2007 — the state’s first large-scale solar power plant application in two decades. But the energy commission currently estimates that it won’t sign off on the license until around 2010, more than six months’ behind schedule as a multitude of state and federal agencies and green groups weigh in on the project’s environmental impact. The clock is ticking as BrightSource needs to start shoveling dirt on the construction site by the end of 2010 to qualify for federal loan guarantees that are part of the Obama stimulus package.

BrightSource may also build solar power plants in Nevada and Arizona, where licensing is easier, to supply electricity to PG&E and Southern California Edison. Woolard says the company controls enough land for nine gigawatts’ worth of solar farms.

While BrightSource’s technology is untested on a large scale, the company has built a six-megawatt demonstration plant in Israel, where its technology development arm is headquartered. BrightSource deploys arrays of mirrors called heliostats that concentrate sunlight on a water-filled boiler that sits atop a tower. The intense heat vaporizes the water to create high-pressure steam that drives a standard electricity-generating turbine.

Woolard says an independent engineering firm, R.W. Beck, has validated the technology at the Negev Desert demo plant. That no doubt helped persuade PG&E, which has sent executives to Israel to inspect the project, to supersize its contract. (And while BrightSource represents the biggest solar deal PG&E has signed, it’s probably far more likely to be fulfilled than the utility’s agreement in April to buy electricity from a space-based solar farm to be built by Southern California startup Solaren.)

“What it came down to is that they saw us delivering,” Woolard says. “Our plant in Israel performed above expectations. The fact that we have a solar plant producing the highest quality, highest temperature, highest pressure steam anywhere in the world is the most important thing.”

The company’s pedigree also provides a certain amount of corporate comfort. BrightSource was founded by American-Israeli solar pioneer Arnold Goldman, whose Luz International built nine large-scale solar trough power plants in the Mojave Desert in the 1980s that continue to generate electricity for Southern California Edison. BrightSource has also raised more than $160 million from a blue-chip group of investors that includes Google (GOOG), Morgan Stanley (MS) and VantagePoint Venture Partners as well as a clutch of oil giants – Chevron (CVX), BP (BP) and Norway’s StatoilHydro.

Google to map green energy zones

siting1

Can Google help defuse a simmering green civil war between renewable energy advocates and wildlife conservationists in the American West?

That’s the idea behind a new Google Earth mapping project launched Wednesday by the Natural Resources Defense Council and the National Audubon Society. Path to Green Energy will identify areas in 13 western states potentially suitable for massive megawatt solar power plants, wind farms, transmission lines and other green energy projects. The app will also pinpoint critical habitat for protected wildlife such as the desert tortoise in California and Wyoming’s sage grouse as well as other environmentally sensitive lands.

“This was information that was unavailable or very scattered,” said Google.org program director David Bercovich at a press conference. “The potential cost savings from this will be enormous. If we can get people to the right areas and streamline the process that will have enormous benefits in getting clean energy online faster.”

NRDC senior attorney Johanna Wald said her group already is using Path to Green Energy in New Mexico to help plan a new transmission project. “Careful siting is the key to renewable energy development,” she said, noting that NRDC has mapped 860 million acres. “We’re not greenlighting development on places that are on our map but we’re providing a framework for discussion.”

siting2The unveiling of Path to Green Energy comes two weeks after California Senator Dianne Feinstein announced she would introduce legislation to put as many as 600,000 acres of the Mojave Desert off limits to renewable energy development to protect endangered wildlife and their habitats.  Solar developers have filed lease claims on a million acres of federal land in the California Mojave and there are state and federal efforts already under way to identify green energy zones across the West.

Path to Green Energy is designed to give regulators and developers a tool to choose the best potential sites for solar and wind farms so they don’t get bogged down in years-long and multimillion-dollar fights over wildlife.  Ausra, BrightSource Energy and other developers of the first half-dozen solar power plant projects moving through the licensing process in California have spent big sums on hiring wildlife consultants who spend thousands of hours surveying sites for desert tortoises, blunt-nosed leopard lizards and other protected species.

The Google Earth app won’t do away with the need to do such detailed environmental review but puts in one package a variety of information that developers must now cobble together themselves — if they can find it. Path to Green Energy could also prove valuable to utilities like PG&E (PCG) and Southern California Edison (EIX) as more and more projects are proposed and regulators scrutinize the cumulative impact of Big Solar power plants across regions.

For instance, in California’s San Luis Obispo County, three large-scale solar farms are being planned within a few miles of each other by Ausra, SunPower (SPWRA) and First Solar (FSLR). That has resulted in delays as wildlife officials initiate studies looking at how all those projects affect the movement of wildlife throughout the area. Going forward, Path to Green Energy will give developers a snapshot of where the wild things are, as well as wildlife corridors to help them avoid siting one plant too close to another in a way that may impede animals’ migration. That could save millions of dollars in mitigation costs – money builders must spend to acquire land to replace wildlife habitat taken for a power plant project as well as avoid fights with environmental groups that have become increasingly uneasy about Big Solar projects.

If the desert tortoise is the critter to avoid when building solar power plants in the Mojave, the sage grouse poses problems for Wyoming wind farms. Brian Rutledge, executive director of Audubon Wyoming, said Path to Green Energy shows the densities of sage grouse across the state, allowing developers to stay clear of those areas.

“We get a solid indication of where energy development shouldn’t go,” he said. “Just as important, we get a better sense of the places that should be evaluated for wind turbine farms and transmission lines. The maps make clear that there is plenty of room for green energy.”

The payback from using Web 2.0 software could indeed be tremendous, given that Google (GOOG) spent a scant $50,000 in donations to NRDC and Audubon to create the maps.

Desert showdown: Big solar vs. little wildlife

California Senator Dianne Feinstein’s move to put a large swath of the Mojave Desert off-limits to renewable energy development is splitting the environmental movement and could derail some two dozen solar and wind power projects the state needs to comply with its ambitious climate change laws.

On the firing line are 17 massive solar power plants and six wind farms planned for federal land — land that would be designated a national monument under legislation Feinstein intends to introduce. The solar projects in question would be built by a range of companies, from startups BrightSource Energy and Stirling Energy Systems to corporate heavyweights Goldman Sachs (GS) and FPL (FPL), according to federal documents. (For the complete list, see below.)

The companies are among scores that have filed lease claims on a million acres of acres of desert dirt controlled by the U.S. Bureau of Land Management. California utilities PG&E (PCG) and Southern California Edison (EIX) have signed long-term power purchase agreements for some of the projects now in jeopardy and are counting on the electricity they would produce to meet state-mandated renewable energy targets. PG&E itself has filed a solar power plant land claim in the proposed national monument.

The area of the desert in dispute is some 600,000 acres formerly owned by Catellus, the real estate arm of the Union Pacific Railroad, and donated to the federal government a decade ago by the Wildlands Conservancy, a Southern California environmental group. About 210,000 of those acres are managed by the U.S. Bureau of Land Management, which opened part of the land to renewable energy projects.

“Many of the sites now being considered for leases are completely inappropriate and will lead to the wholesale destruction of some of the most pristine areas in the desert,” Feinstein wrote in a letter to Interior Secretary Ken Salazar released last week, notifying him that she will introduce legislation to designate the former Catellus lands a national monument. “Beyond protecting national parks and wilderness from development, the conservation of these lands has helped to ensure the sustainability of the entire desert ecosystem by preserving the vital wildlife corridors.”

The Catellus land controlled by the BLM forms something of a golden triangle between the Joshua Tree National Park and the Mojave National Preserve in Southern California and are particularly coveted for renewable energy development because of its proximity to transmission lines.

Alan Stein, a deputy district manager for the BLM in California, told Green Wombat that the solar and wind lease claims are in areas that are not designated as wilderness or critical habitat for protected species like the desert tortoise. “This is public domain land, ” he says.

Tortoises, however, are found across the Mojave, and battles over Big Solar’s impact on endangered wildlife are quietly brewing in several solar power plant licensing cases now being reviewed by the California Energy Commission.  Environmentalists find themselves walking a thin green line, trying to balance their interest in promoting carbon-free energy with protecting fragile desert landscapes and a host of threatened animals and plants.

Take BrightSource Energy’s Ivanpah 400-megawatt solar power plant complex on the California-Nevada border. The three solar power plants to be built by the Oakland-based company will supply electricity to PG&E and Southern California Edison. But the project will also destroy some 4,000 acres of desert tortoise habitat and at least 25 tortoises will have to be relocated – a somewhat risky proposition as previous efforts in other cases have resulted in the deaths of the animals.

On Wednesday, the California Energy Commission granted two national environmental groups – the Defenders of Wildlife and the Sierra Club – the right to intervene in the Ivanpah case. “Defenders strongly supports … the development of renewable energy in California,” Kim Delfino, California program director for Defenders of Wildlife, wrote to the energy commission in a Jan. 23 letter.  “Defenders has several serious concerns about the potential impacts of this project on a number of rare, declining and listed species and on their associated desert habitat and waters.”

Natural Resources Defense Council attorney Johanna Wald wrote a letter with the Wilderness Society expressing concern over the impact of Ivanpah project on the desert tortoise but also made a strong statement of support for renewable energy development. “Our public lands harbor substantial wind, solar, and geothermal resources,” wrote Wald, who serves on a state task force to identify appropriate areas for renewable energy development. “Developing some of these resources will be important to creating a sustainable energy economy and combating climate change.”

The big national enviro groups are working with the government and power plant developers to create zones in the Mojave where renewable energy projects would be permitted while setting aside other areas that are prime habitat and wildlife corridors. A similar effort is underway on the federal level to analyze the desert-wide impact of renewable energy development.

Local environmental organizations, however, have split with the Big Green groups over developing the desert and other rural areas. In San Luis Obispo County,  Ausra, SunPower (SPWRA) and First Solar’s (FSLR) plans to build three huge solar farms within miles of each other has prompted some local residents worried about the impact on wildlife to organize in opposition to the projects.

And some small Mojave Desert green groups pledge to go to court to stop big solar projects. “We don’t want to see the Endangered Species Act gutted for the sake of mega solar projects,” veteran grass roots activist Phil Klasky told Green Wombat last year for a story on the solar land rush in the Mojave. “I can say the smaller environmental organizations I’m involved with are planning to challenge these projects.”

It would be unwise to underestimate Klasky. In the 1990s, he helped lead a long-running  and successful campaign to scuttle the construction of a low-level radioactive waste dump in tortoise territory in the Mojave’s Ward Valley – now a prime solar spot.

Still, while California’s senior senator’s move in the Mojave may exacerbate rifts in the environmental movement over renewable energy, it also could galvanize efforts to resolve critter conflicts in a comprehensive way. Otherwise, environmentalists of varying hues may find themselves fighting each other rather than global warming.

Update: I just had a conversation with BrightSource spokesman Keely Wachs, who takes issue with my characterization that the Ivanpah project will “destroy” desert tortoise habitat. He points out that the company is taking care to minimize the impact of the power plant on the surrounding desert and that wildlife may still occupy the site. It would be more accurate to say that the project will remove desert tortoise habitat from active use during Ivanpah’s construction and operation.

New Mexico gets first Big Solar farm

The arid Southwest has no shortage of sun but has been rather slow to embrace Big Solar power plants, at least compared to California, where more than a half-dozen massive megawatt solar farms are being licensed.

That appears to be changing. On Tuesday, First Solar said it will give New Mexico its first big solar power plant, a 30 megawatt photovoltaic farm that will generate electricity from the company’s thin-film panels. Once the plant is built in Colfax County in northeastern New Mexico, First Solar will sell the electricity it generates to the Tri-State Generation and Transmission Association under a 25-year power purchase agreement. Tri-State is an electric cooperative.

The deal continues First Solar’s (FSLR) move into the power plant business. Earlier this month, the Tempe, Ariz.-based company acquired OptiSolar’s 1.85 gigawatt project portfolio – including a 550-megawatt photovolatic power plant for California utility PG&E (PCG) – in a $400 million stock transaction.

First Solar has also signed contracts for smaller-scale solar farms with Southern California Edison (EIX) and Sempre (SRE).

Big Solar’s software solution

SAN FRANCISCO — “It’s all about the software,” says eSolar CEO Bill Gross.

The tech entrepreneur and founder of startup incubator Idealab is explaining how eSolar’s solar power plants can produce carbon-free electricity cheaper than planet-warming natural gas. At the Cleantech Forum in San Francisco, Gross flashes a photo of eSolar’s demonstration solar farm outside the Southern California town of Lancaster, where 24,000 mirrors called heliostats surround two 150-foot towers.  The heliostats concentrate sunlight on a tower containing water-filled boilers and the resulting heat creates steam that drives an electricity-generating turbine. Rivals like BrightSource Energy use similar “power tower” technology but according to Gross, eSolar’s mirror-controlling software and modular plant design will allow it to produce cheaper solar electricity.

For instance, Gross says competitors use large, slightly curved mirrors to focus sunlight. That require big and expensive steel frames to hold the glass in place.  eSolar’s solution: make small flat mirrors the size of an LCD television screen that clamp on to a  5 x 12-inch frame and then use software and Big Iron computing to position the mirrors to create a parabola out of the entire heliostat field.

“We use Moore’s law rather than more steel,” quipped Gross, referring to Intel co-founder Gordon Moore’s maxim that computing power doubles every two years.

The heliostats roll off an assembly line in China with the wiring and sun-tracking motors built in. “The only tool required to install mirrors in the field is a hand wrench,” Gross says. “There’s  no welding in field, you just install the mirrors on the base. We’ve taken all the labor in the field and moved it to an automated factory.”

The heliostats also do not have to be precisely placed in the solar field, which saves time. “The rows can be wavy as the software will correct for it,” Gross notes. “We don’t need to do extensive surveys to design the field; we just need to leave enough space between mirrors.”

The bottom line: The five-megawatt Palmdale project was built in less than six months. “We think we can finish plants before other people start,” Gross told Green Wombat.

Gross says eSolar has also signed a 92-megawatt deal with a New Mexico utility, which he declined to identify until the agreement is announced. He said his Pasadena, Calif.-based company will also soon unveil a contract to build 500 megawatt’s worth of solar farms in Asia. So far, eSolar has spent $30 million acquiring land – mainly privately owned agricultural property – for solar power plants, according to Gross. He told Cleantech Forum participants that eSolar expects internal rates of return for its partners of between 11% and 14% for U.S. power plants and returns of 20% to 30% for overseas projects.

Also saving time and money are the power towers, which are made from two sections of a windmill tower. At 150 feet they’re half the size of competitors’ towers – again, less steel is needed. The lower height and the software systems that allow more mirrors to be crammed into smaller spaces means that eSolar’s power plants can be placed closer to urban areas where transmission lines are available.

Also unique is the boiler that sits atop the tower. Gross gave Green Wombat a close-up look the proprietary technology. About the size of a cargo shipping container, the “cavity receiver” has openings on either side. The heliostats focus sunlight into the interior of the boiler, which is lined with water-filled pipes.

“The benefit is that the light comes in and even if some light is reflected it can have multiple bounces and still hit the pipes,” Gross says. “We can get all the light inside the cavity all because of the software that controls the mirrors.”

Whether Google (GOOG)-backed eSolar’s plants produce electricity at the low rates Gross is claiming won’t be known until they start coming online. But utilities are betting that this solar software works. Southern California Edision (EIX) last year signed a 20-year-contract with eSolar for 245 megawatts of electricity while coal-dependent NRG Energy (NRG) this week agreed to invest $10 million in eSolar in exchange for the right to develop up to 500 megawatts using the company’s technology. (Southern California Edison is betting even bigger on BrightSource Energy’s power tower technology – two weeks ago the utility signed a 1,300 megawatt power purchase agreement with the Oakland startup – also backed by Google – the world’s largest solar deal to date.)

PG&E chief: We’ll be solar’s ‘green knight’

SAN FRANCISCO — With the financial crisis dimming solar’s prospects to become a significant source of renewable energy, utility giant PG&E on Tuesday said it will spend $1.4 billion over five years to install 250 megawatts’ worth of photovoltaic panels in California while contracting with private developers for another 250 megawatts. PG&E chief executive Peter Darbee said the utility is also prepared to be a “green knight,” rescuing distressed big centralized solar power plant projects by providing financing so they can get built.

“We have contracted for 24% of our energy to be renewable and we’re concerned whether our [developers] will have access to capital,” Darbee said at PG&E’s San Francisco headquarters during a press conference. “We think financing for these projects may be in jeopardy. PG&E is well-positioned with its $35 billion balance sheet to step up and help.”

PG&E’s (PCG) move to take a direct role in obtaining the renewable energy it needs to comply with California’s global warming laws could be big business for solar module panel makers and installers like SunPower (SPWRA), Suntech (STP) and First Solar (FSLR). The action was prompted in part by a change in the tax laws that lets utilities claim a 30% investment tax credit for solar projects.

Fong Wan, PG&E’s vice president for energy procurement, said most of the 500 megawatts of solar panels will be installed on the ground in arrays of between one and 20 megawatts at utility substations or on other PG&E-owned property. (The utility is one of California’s largest landowners.) A small portion may be installed on rooftops, he said.

PG&E said the solar initiative will generate enough electricity to power 150,000 homes and will provide 1.3% of the utility’s electricity supply.

“There’s no or little need for new transmission and these projects can plug directly into the grid,” said Darbee. “Given our size and our credit ratings and our strength, we can move forward where smaller developers may not be able to do so.”

The California Public Utilities Commission must approve PG&E’s solar initiative, which Wan estimated would add about 32 cents to the average monthly utility bill.  An $875 million program unveiled by Southern California Edison (EIX) last year to install 250 megawatts of utility-owned rooftop solar panels has run into opposition from solar companies that argue it is  anti-competitive and from consumer advocates who contend the price is too high. The state’s third big utility, San Diego Gas & Electric (SRE), has also proposed a rooftop solar program.

Wan acknowledged that objections to Edison led PG&E to design its program so that private developers would have a 50% stake in the initiative. PG&E will sign 20-year power purchase agreements for privately owned solar installations.

PG&E will also need regulators’ approval to inject equity financing into companies developing big solar power plants. The utility has signed power purchase agreements for up to 2,400 megawatts of electricity to be produced by solar thermal  and photovoltaic power plants to be built by companies like Ausra, BrightSource Energy, OptiSolar and SunPower.

“We are looking at the least risky and most developed opportunities to see where we can be the most helpful,” Darbee said.

Coal-fired utility signs big solar deal

NRG Energy, one of the United States’ most coal-dependent utilities, on Monday signed a deal with California startup eSolar to develop solar power plants.

The agreement calls for NRG  to invest $10 million in Pasadena-based eSolar for the right to use the startup’s technology to develop and operate three solar power projects in California and the Southwest that would generate 500 megawatts of greenhouse gas-free electricity.  NRG ranks as one of the nation’s dirtiest utilities,  spewing 70 million tons of carbon dioxide annually from its coal-fired power plants, according to a 2007 Fortune Magazine story.  But the Princeton, N.J.-based Fortune 500 company has sought to clean up its ways under CEO David Crane, pursuing carbon-capture technology and moving to build nuclear power plants.

Last year eSolar, founded by Idealab’s Bill Gross and backed by Google, won a 20-year contract to supply utility Southern California Edison (EIX) with 245 megawatts of green electricity annually. Last  April, eSolar scored $130 million in funding from Google.org, Google’s (GOOG) philanthropic arm, and other investors to develop solar thermal technology that Gross claims will produce electricity as cheaply as coal-fired power plants.

Like rivals Ausra and BrightSource Energy – which have deals with utility PG&E (PCG) – eSolar will use fields of mirrors to heat water to create steam that drives electricity-generating turbines. Gross says that eSolar’s software allows the company to individually control smaller sun-tracking mirrors – called heliostats – which can be cheaply manufactured and which are more efficient and take up less land than conventional mirrors. According to Gross, that means eSolar can build modular power plants near urban areas and transmission lines rather than out in the desert, lowering costs.

In October, eSolar’s then-CEO told Green Wombat that the company was more interested in being a solar technology provider than a power plant construction company.

The eSolar deal gives NRG (NRG), which operates coal-fired power plants in Texas and the Northeast, a foothold in the California renewable energy market. The first solar farm will go online in 2011 and NRG will have the right to develop 11 of eSolar’s 46-megawatt modular power plants. eSolar currently is building a five-megawatt demonstration power plant in Lancaster, Calif., that is expected to be completed this year.

“By coupling NRG’s construction capabilities and regional operating expertise with eSolar’s innovative … technology, we can advance NRG’s renewable energy portfolio while helping to accelerate development of these important projects on a commercial scale,” said NRG executive Michael Liebelson in a statement.

During a press conference Monday, Liebelson said NRG would be able to take advantage of the 30% investment tax credit for renewable energy projects and intends to apply for federal loan guarantees for such power plants that were included in the recently enacted stimulus package.

The deal, coming less than two weeks after BrightSource Energy signed a 1,300-megawatt power purchase agreement with Southern California Edison, shows that despite the financial crisis the market for renewable energy is showing renewed signs of life.

California’s green energy spike

cpuc-rps-report

California quadrupled the amount of renewable energy it installed in 2008 over the previous year, according to a report released Wednesday by the state’s Public Utilities Commission.

The 500 megawatts of green electricity brought online last year represents 60% of all renewable energy generation built since 2002, when California mandated that the state’s investor-owned utilities obtain 20% of their power from renewable sources by 2010. In November, Governor Arnold Schwarzenegger signed an executive order raising the Renewable Portfolio Standard, or RPS, to 33% by 2020.

“Clearly, 2008 was a turning point for the RPS program and contracted projects are beginning to deliver in large numbers,” the California Public Utilities Commission report stated.

The CPUC in 2008 approved projects that would generate 2,812 megawatts of renewable energy for California’s Big Three utilities – PG&E (PCG), Southern California Edison (EIX) and San Diego Gas & Electric (SRE). Impressive numbers but the utilities have acknowledged they are unlikely to meet their renewable energy targets by the 2010 deadline because it takes years to get solar and wind projects online and some will inevitably fail. For instance, the financial crisis has raised questions about just how many of the Big Solar power plants the utilities are relying on will actually get built, though the $787 billion stimulus packaged signed into law Tuesday by President Barack Obama has brightened the solar industry’s prospects.

California increasingly is depending on solar energy to meet its commitments to reduce greenhouse gas emissions under the state’s landmark 2006 global warming law. According to regulators, utilities received 30% more bids for solar power projects in 2008 than in the previous year while wind farm proposals dropped by half and “very few” geothermal tenders were filed.

The fact that utilities received 24,000 megawatts’ worth of renewable energy bids last year (more than enough, if built, to meet the 33% renewable energy target) speaks to the frothy state of the market. But before solar power plants and other green energy projects can go online they face years-long and often contentious environmental reviews, while a lack of transmission lines to bring all this electricity from the desert to coastal cities remains the green elephant in the room.

Meanwhile, regulators are reviewing a policy change that would seem to undercut the state’s goal of encouraging utilities to generate more renewable energy. On March 12 Feb. 20,the California Public Utilities Commission will consider whether to allow utilities to buy so-called tradable renewable energy credits, or TRECs, from other entities  to meet their green electricity mandates. Such credits are associated with the electricity generated by wind farms, solar power plants and other projects and can be bought and sold. In other words, if a utility finds itself falling short of its renewable energy goals – or just doesn’t want to spend the money procuring green power – it could buy TRECs on the open market.

Green Wombat is awaiting a reply from the utilities commission on whether California utilities could purchase TRECs generated by out-of-state projects – which, of course, would do nothing to reduce the state’s own greenhouse gas emissions.  UPDATE: CPUC spokeswoman Terrie Prosper says that utilities will be able to buy out-of-state TRECs as long as they meet California’s eligibility requirements.

In the green stimulus sweepstakes, big potential winners are companies like Silicon Valley startup OptiSolar.

The solar-cell maker came out of nowhere last year to score a deal with utility PG&E to build the world’s largest photovolaic power plant, a 550-megawatt monster that would cover some 9 1/2 square miles on California’s central coast. OptiSolar subsequently began construction of a factory in Sacramento to produce the thousands of thin-film solar panels needed for the project. Then the economy tanked and as financing dried up, OptiSolar laid off half its workforce – some 300 employees – and halted construction of the Sacramento facility.

With a Colorado solar company executive joining President Barack Obama as he signed the $787 billion stimulus legislation into law Tuesday at a solar-powered museum in Denver, OptiSolar and other renewable energy companies stalled by the financial crisis may see their fortunes revive. The package allows builders of big renewable energy projects to apply for a government cash grant to cover 30% of construction costs in lieu of claiming a 30% investment tax credit. A dearth of investors who finance solar power plants and wind farms in exchange for the tax credits has put in jeopardy green energy projects planned for the desert Southwest and the Great Plains. The cash grant would shave about $300 million off the projected $1 billion price tag for OptiSolar’s Topaz Solar Farm.

The stimulus package also includes $2.3 billion to fund a 30% manufacturing tax credit for equipment used to make components for green energy projects, a provision OptiSolar can tap to help finance its solar cell factories. And the company may be able to take advantage of the legislation’s government loan guarantees for large renewable energy projects.

“It will lower the cost of the factory we’re building in Sacramento and make it easier to attract financing,” OptiSolar spokesman Alan Bernheimer told Green Wombat, noting the company’s priority is to complete the facility and begin production of solar panels. “The factory is more than shovel ready – our shovels are hanging on the wall where we put them when we had stop work in November.” (OptiSolar currently manufactures solar modules at its Hayward, Calif., plant.)

Fred Morse, senior adviser to Spanish solar energy giant Abengoa, says the stimulus package puts back on track a $1 billion, 280-megawatt solar thermal power plant the company will build outside Phoenix to produce electricity for utility Arizona Public Service. “With the stimulus bill we’re very confident we’ll be able to finance the project,” says Morse. He says Abengoa expects to use the government loan guarantees to obtain debt financing to fund construction of the project and then apply for the 30% cash refund. “I think the entire industry is very optimistic that these two aspects of the stimulus package, the grants and the temporary loan guarantees, should allow a lot of projects to be built.”

Mark McLanahan, senior vice president of corporate development for MMA Renewable Ventures, agrees. “I expect the government grants to attract new investors,” says McLanahan, whose San Francisco firm finances and owns commercial and utility-scale solar projects.

There are some strings attached, though.

To qualify for the cash grants, developers need to start shoveling dirt by Dec. 31, 2010. That means only a handful of big solar thermal power plants planned for California, for instance, are likely to make it through a complicated two-year licensing process in time to break ground by the deadline. One of those could be the first phase of BrightSource Energy’s 400-megawatt Ivanpah power plant on the California-Nevada border. But BrightSource’s biggest projects, part of a 1,300 megawatt deal signed with Southern California Edison (EIX) last week, won’t start coming online until 2013 at the earliest.

Another Big Solar project, Stirling Energy Systems’ 750-megawatt solar dish farm for San Diego Gas & Electric (SRE), will be racing to meet the 2010 deadline. The project is in the middle of a long environmental review by the California Energy Commission and the U.S. Bureau of Land Management which currently is scheduled to stretch into 2010.

SolarReserve CEO Terry Murphy says his Santa Monica-based startup has a couple of solar power plant projects in the works that should be able to take advantage of the stimulus provisions. “The likelihood of us being able to close on a financial deal has increased,” Murphy says.

Solar analyst Nathan Bullard of research firm New Energy Finance expects the stimulus package to prompt a push for large photovoltaic power projects. That’s because in California such solar farms – which essentially take rooftop solar panels and mount them in huge arrays on the ground – do not need approval from the California Energy Commission and can be built relatively quickly.

That’s good news for companies like thin-film solar cell maker First Solar (FSLR), which builds smaller scale photovoltaic power plants, and SunPower (SPWRA), which has a long-term contract with PG&E (PCG) for the electricity generated from a planned 250-megawatt PV solar farm to be built near OptiSolar’s project.

“It’s great for PV because you can definitely can get construction done by the end of 2010,” says Bullard. “It’s also good news for smaller and mid-sized developers who couldn’t access tax-equity financing.”

The catch, however, is that renewable energy companies still must raise money from investors in a credit-crunched market to cover construction costs, as the government doesn’t pay out the cash until 60 days after a solar power plant or wind farm goes online. And as McLanahan points out, the cost of raising capital from private equity investors is typically higher and will add to the cost of renewable energy projects. Those costs will only rise if the government is late in paying out refunds.

MMA Renewable finances large commercial arrays and solar power plants and then sells the electricity under long-term contracts to customers who host the solar systems. The loan guarantee provision of the stimulus legislation will help secure financing from investors skittish that some of MMA Renewable’s customers may default on their agreements, according to McLanahan.

Says Murphy: “The fact that we’re getting iron into the ground and getting things moving helps us.”

The wind industry also stands to gain from the stimulus package through a three-year extension of the production tax credit for generating renewable electricity as well as the government cash grants and manufacturing tax credit. Despite a record year for wind farm construction in 2008, projects have come to a standstill in recent months as the financial crisis froze development and forced the European-dominated industry to lay off workers.

“I think it’s good down payment on what needs to happen,” says Doug Pertz, CEO of Clipper Windpower, one of two U.S. wind turbine makers. “A lot more needs to be done but I think this will start to bring a lot of people back into the marketplace.”
