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.”

A ray of sunshine amid the economic gloom: While some solar companies struggle through the downturn, BrightSource Energy on Wednesday morning announced the world’s largest solar energy deal to date – a 20-year contract to supply utility Southern California Edison with 1,300 megawatts of greenhouse gas-free electricity.

That’s more than twice the size of the previous world’s-biggest-solar-deal, a 553-megawatt power purchase agreement in 2007 between California utility PG&E and Israel’s Solel. BrightSource itself last year inked a deal to provide PG&E (PCG) with 500-megawatts of solar electricity with an option for 400 megawatts more.

“This proves the energy industry is recognizing the role solar thermal will play as we de-carbonize our energy supply,”  BrightSource CEO John Woolard said Wednesday at a press conference.  “We believe now more than ever the time is right for large-scale solar thermal.”

solarhOakland-based BrightSource will build seven solar power plants for Southern California Edison (EIX) using its “power tower” technology. Thousands of sun-tracking mirrors called heliostats focus the sun’s rays on a water-filled boiler that sits atop a tower. The intense heat creates steam which drives a turbine to generate electricity. BrightSource has built a prototype power plant in Israel.

BrightSource has 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.

If all the solar power plants are built, BrightSource’s deal with Southern California Edison will generate enough electricity to power about 845,000 homes. The agreement is a vote of confidence in the solar industry at a time when the financial crisis has forced BrightSource rivals like OptiSolar to lay off workers while Ausra retools its strategy to focus on supplying solar thermal technology to power plant developers rather than building projects itself.

Given the economic collapse, why are these massive megawatt deals still being done? First, California utilities are under tight deadlines to ratchet up the amount of electricity they obtain from renewable sources – 20% by the end of 2010 and 33% by 2020. Second, it costs nothing to sign a contract – no money has yet changed hands, and won’t unless the plants are built and begin producing electricity.

In fact, not a kilowatt of juice has been generated from the more than 5,000 megawatts of Big Solar contracts signed over the past four years by California’s three investor owned utilities (the third being San Diego Gas & Electric (SRE) ).  Still, a long-term utility contract is key for a startup like BrightSource to obtain the billions in financing required to build large-scale solar power plants. The terms of utility contracts – such as the cost of the solar electricity produced – are closely held secrets but are worth billions, if a 2008 power purchase agreement between Spanish solar company Abengoa and utility Arizona Public Service is any guide.

A significant hurdle for BrightSource – and many other solar developers – is the expansion of the transmission grid to connect remote power plants to cities. BrightSource spokesman Keely Wachs says the company has 4,200 megawatts of solar power plant projects under development.

The Southern California Edison deal is something of a homecoming for American-Israeli solar pioneer Arnold Goldman, BrightSource’s founder and chairman. In the 1980s, during the first solar boom, his Luz International built nine solar power plants in the Mojave. Those plants, most are now operated by FPL (FPL), continue to provide electricity to Edison.

The first BrightSource solar farm for Edison is expected to go online in early 2013. It’s a 100 megawatt power plant part of BrightSource’s Ivanpah complex to be built on federal land on the California-Nevada border in the Mojave Desert. That plant is currently wending its way through a complex state and federal licensing process.

Just how complex was illustrated by a meeting Green Wombat attended Tuesday in Sacramento, where a roomful of state and federal officials spent hours discussing the environmental impact of a 750-megawatt solar power plant to be built by Phoenix’s Stirling Energy Systems for San Diego Gas & Electric that would plant 30,000 solar dishes in the desert. A second Stirling solar farm will be built for Southern California Edision. When the deals were announced in 2005, they were the world’s largest at the time.

PG&E chief executive Peter Darbee recently said his utility will begin directly investing in solar power projects. On Wednesday, Southern California Edison renewable energy executive Stuart Hemphill said Edison would consider requests from solar power developers to take ownership stakes in their projects but prefers to sign power purchase agreements.

“We do see solar as the large untapped resource, particularly in Southern California,” said Hemphill.

Over the weekend The New York Times’ Matthew L. Wald had a sobering story on the not-inconsiderable challenges facing efforts to expand and upgrade the United States’ power grid to tap renewable energy from wind farms and solar power plants. Among them: Opposition to new high-voltage power lines from landowners and environmentalists, a Byzantine permitting process and fights over who pays the costs of transmission projects that span state lines.

Here in California, the ongoing controversy over the Sunrise Powerlink project is a case study in just how difficult it will be to build the infrastructure to transmit electricity from dozens of solar power plants planned for the Mojave Desert. Among the big companies looking to cash in on the solar land rush: Goldman Sachs (GS), Chevron (CVX) and FPL (FPL)

Utility San Diego Gas & Electric first proposed the $1.3 billion, 150-mile Sunrise Powerlink in 2005 to connect the coastal metropolis with remote solar power stations and wind farms in eastern San Diego County and the Imperial Valley. For instance, SDG&E’s contract to buy up to 900 megawatts of solar electricity from massive solar farms to be built by Stirling Energy Systems is dependent on the construction of the Sunrise Powerlink. Like California’s other big investor-owned utilities – PG&E (PCG) and Southern California Edison (EIX) – SDG&E, a unit of energy giant Sempra (SRE), is racing the clock to meet a state mandate to obtain 20% of its electricity from renewable sources by 2010 and 33% by 2020.

But Sunrise sparked opposition from the get-go as the utility proposed routing part of the transmission project through a pristine wilderness area of the Anza-Borrego Desert State Park.  The prospect of 150-foot-tall transmission towers marching through critical habitat for desert tortoises and other protected wildlife galvanized environmentalists well-versed in the arcane arts of regulatory warfare.

Opponents also painted the project as a Trojan horse to bring in cheap coal-fired power from Mexico. (Wald makes a similar point in his Times‘ piece – the same high-voltage lines designed to transmit green electricity from wind farms can also be used to send cheap carbon-intensive coal-fired electricity across the country.) That argument subsequently lost currency when regulators, citing California’s landmark global warming law, barred utilities from signing long-term contracts for out-of-state coal power.

After more than three years of hearings and procedural skirmishes culminating in an 11,000-page environmental impact report, a PUC administrative law judge last October issued a 265-page decision all but killing the project on environmental grounds. Whether SDG&E thought that green energy and climate change concerns would trump worries over wildlife and wilderness, it was clear that trying to build an industrial project through a state park was a costly mistake.

Then in December, after California Governor Arnold Schwarzenegger signed an executive order to streamline and prioritize the licensing of renewable energy projects, the utilities commission’s board revived Sunrise Powerlink, approving a different route for the transmission lines that avoids Anza-Borrego.

But the fight is far from over. With the cost of the project now approaching $2 billion, late last month the Center for Biological Diversity, a Tucson, Ariz.-based environmental group, filed a suit in the California Supreme Court challenging the utilties commission’s approval of Sunrise Powerlink.

Safe to say, the battle will drag on for some time to come, giving new meaning to the term “stranded assets” for some would-be Big Solar developers.

As the financial crisis short-circuits the ambitions of green tech companies, solar financier MMA Renewable Ventures is pushing ahead with raising its fifth fund. Meanwhile, its solar power plant joint venture with Chinese solar cell maker Suntech – Gemini Solar Development – has been selected by utility Austin Energy to build a 30-megawatt solar farm in Texas.

The San Francisco-based firm just completed its $200 million Solar Fund III, which invested in 20.6 megawatts of photovoltaic solar arrays for companies like Macy’s, the Gap, Lowe’s and utility FPL (FPL) as well as the Denver International Airport. MMA Renewable (MMAB.PK) provides the financing for the installation of large commercial solar arrays on big box stores and other locations while retaining ownership of the systems. The electricity produced is sold to the building owner under a long-term contract.

“The good news is that we can raise another fund in a tough market,” MMA Renewable Ventures CEO Matt Cheney told Green Wombat, adding that the company aims to raise $200 million or more for Solar Fund V.

That doesn’t mean it’ll be easy. Many of the Wall Street banks that invested in big solar systems are no more and demand for the tax credits generated by the projects has fallen faster than the Dow Jones as most companies aren’t piling up much tax liability these days.

“The ones that are left are being very picky and asking a lot,” says Cheney, adding that banks and other investors are demanding higher returns on their investments. Still, he notes, past MMA Renewable investors like Wells Fargo (WFC) remain relatively healthy. “If you look at every country in Europe and the U.S., there are good examples of financing institutions that were less impacted by the financial crisis, which is a deep one,” he says.

One possible source of new tax-equity investment may come from well-capitalized utilities that, thanks to a change to the tax laws Congress made last October, can now claim tax credits for solar projects. PG&E (PCG) CEO Peter Darbee, for instance, has said his utility plans to invest in solar power plants.

A new and potentially bigger worry is whether MMA Renewable customers – big box retailers and the like – will be survive the financial crisis. MMA Renewable’s business is built on long-term power purchase contracts – as long as 20 years – that provide a predictable and steady revenue stream to investors.

“Would you buy a corporate bond from a large U.S. company that went out 20 years today?” Cheney asks. “You would most likely tell me that’s a long time. You don’t know if you want to take that risk beyond five or ten years. That’s the equation that’s present in the marketplace today.”

In California, at least, demand for solar has remained strong: This week state regulators reported that installed solar systems more than doubled in 2008 from the previous year.

One bright spot may be the market for smaller-scale photovoltaic power plants and MMA Renewable’s Gemini joint venture with Suntech (STP).  The Austin Energy project still must be approved by the city of Austin, but Cheney says Gemini is in the midst of negotiations with other utilities as well.

When SunPower (SPWRA) reported record fourth-quarter earnings Thursday, CEO Tom Werner said the Silicon Valley solar cell maker was shifting resources to its power plant building business in 2009 and had 1,000 megawatts of projects on the drawing boards.

There was just one catch:  money. “We have a strong pipeline of projects fully permitted, or with permits in process, that will be buildable,” Werner said, ” when financing becomes available.”

When Green Wombat sat down for a chat with Ausra founder David Mills back in September 2007, he allowed that it was not unreasonable to expect the Silicon Valley solar startup to soon be building several massive megawatt solar power plants a year. The optimism was not unwarranted. After all, in the space of 12 months Ausra had relocated from Sydney to Palo Alto, raised $40 million from A-list venture capitalists and was about to ink a deal with utility PG&E for a 177-megawatt  solar power project.

That was then. This month Ausra laid off 10% of its 108 employees amid a move to stop building Big Solar projects – for now – to focus on providing its solar thermal technology to other power plant developers and to industries that use steam. (Ausra’s compact linear fresnel reflector technology deploys flat mirrors that sit low to the ground and concentrate sunlight on water-filled pipes that hang over the mirrors. The superheated water creates steam which drives an electricity-generating turbine.)

“I think our competitors will figure this out sooner or later but nobody’s going from a five-megawatt project to a 500-megawatt project. No one’s going to finance that,” Ausra CEO Bob Fishman told Green Wombat. “If you look at the amount of money it takes to be involved in the project development business, that’s not something a startup can do.”

At least any time soon. Ausra last year opened a robotic factory in Las Vegas to make mirror arrays and other components for the many power plant projects it had on the drawing boards. Just three months ago the company flipped the switch on its five-megawatt Kimberlina demonstration power plant outside Bakersfield. But as the credit crunch hit, financing for billion-dollar solar power projects evaporated. Then in October, Congress passed legislation allowing utilities like PG&E (PCG), Southern California Edison (EIX) and San Diego Gas & Electric (SRE) to claim a 30% investment tax credit for solar projects. As the only well-capitalized institutions left standing in the energy game, utilities are stepping forward as investors.

PG&E CEO Peter Darbee says he’s prepared to make direct investments in solar power plants – projects the utility needs to comply with a California mandate to obtain 20% of its electricity from renewable sources by 2010 and 33% by 2020. Under pressure to meet those targets, California utilities have signed more than four gigawatts worth of power purchase agreements with solar power plant startups like BrightSource Energy, Solel, Stirling Energy Systems and eSolar. Utilities also have begun signing deals for electricity produced by smaller scale photovoltaic power plants built by companies like First Solar (FSLR) and SunPower (SPWRA).

Fishman said Ausra will complete the 177-megawatt Carrizo Energy Solar Farm in San Luis Obispo County on California’s central coast to supply electricity to PG&E. “If Peter Darbee wants to own Carrizo rather than buy the electricity, we’re willing to do it. It makes sense,” he says.

Ausra will also will complete a second big solar power plant planned for Arizona. But the company has quietly let drop a Florida project for utility FPL (FPL) and is negotiating to offload lease claims it filed on federal land in Arizona and Nevada for solar power plants during the solar land rush.

“Other projects in the pipeline we’ll be selling to utilities or developers for a modest amount of cash with a commitment that those developers must use our technology,” says Fishman.

Fishman notes that the cost of licensing a solar power plant can be $5 million to $10 million a year – and in California it’s a multi-year process – so Ausra will realize some immediate savings by morphing into a technology provider.

Customers for Ausra’s technology include oil companies that could inject solar-generated steam in oil wells to enhance recovery of thick petroleum as well as food processing plants and other heavy users of steam. Fishman just returned from a trip to the Middle East where he says he held talks in Kuwait, Qatar and Dubai about using Ausra’s technology for oil recovery and desalinization.

Going forward, he says Ausra’s focus will be on medium-sized power plants. “Maybe next year we’ll do four projects of 50 megawatts a year. It’s a walk before you run situation,” says Fishman. “The financial customers and financial community are going to insist we do medium scale before we do large scale. We’ll still want to do very large projects but given the project finance market, it’ll be a few years from now.”

The Federal Energy Regulatory Commission, or FERC, is one of those acronym agencies that regulates a key aspect of the United States economy – the electricity grid – but tends to operate under the radar.

Not any more. With President Barack Obama’s appointment of FERC Comissioner and renewable energy advocate Jon Wellinghoff as the agency’s acting chairman, FERC will play a key role in the administration’s efforts to digitize the nation’s aging analog power grid to promote solar and wind energy while creating green jobs. The largest chunk of the stimulus package devoted to renewable energy – some $54 billion – has been set aside for modernizing the grid.

At a Nov. 18 briefing on Capitol Hill, Wellinghoff showed that he’s been thinking extensively about how to upgrade the grid to connect renewable energy produced in remote areas to population centers on the coasts. “In the whole Midwest of this country there are virtually no high- voltage transmission lines,” he said, displaying Google’s  (GOOG) proposal to wean the U.S. from fossil fuels by 2030.  “If you overlay where the wind is, all the wind is in the middle of this country – all those areas where we do not have sufficient transmission. Hopefully we can get the structure to put renewables on the grid and improve the grid to make it a smart system that can ultimately deliver these resources in an efficient way.”

Wellinghoff in a December interview with EnergyWashington.com advocated reviving domestic manufacturing of big transformers – now made overseas – to support the expansion of high-voltage power lines across the U.S.

On Monday, Wellinghoff called for electric cars to be integrated into the electric grid, according to a report by Dow Jones. He said FERC could structure rates to pay car owners for returning electricity to the grid from their vehicle batteries to help balance the power supply as more solar, wind and other intermittent sources of energy come online.

At the November briefing, Wellinghoff called electric cars part of “the glue” that will hold a green grid together and said the federal government should consider giving automakers like General Moters (GM) and Ford (F) incentives to produce plug-in hybrids.

“To modernize the grid, we need to define our goals and define a national tranmission planning process,” he said. “Let’s do it. We just need to get it done.”

With Big Solar thermal power plants bogged down in bureaucracy and facing environmental and financial hurdles, utilities are turning to smaller-scale thin-film solar stations that can be built in a matter of months.

In late December, PG&E (PCG), for instance, signed a 20-year contract for electricity generated  from a 10-megawatt thin-film solar power plant in Nevada owned by energy giant Sempra (SRE) that was officially dedicated on Thursday. The solar farm was built by First Solar (FSLR) in a scant six months. Meanwhile, the utility’s nearly two gigawatts worth of deals with solar thermal power companies won’t start producing power for another two years at the earliest. (Southern California Edison (EIX) and San Diego Gas & Electric signed agreements with solar dish developer Stirling Energy Systems for 1.75 gigawatts in 2005 and those projects are just now beginning to move through the regulatory approval process.) And the financial crisis has made it more difficult for solar thermal developers to obtain the billions of dollars needed to finance the construction of a massive megawatt power plant.

Solar thermal power plants typically use miles of mirrors to heat a fluid to create steam which drives an electricity-generating turbine. Photovoltaic (or PV) solar farms essentially take solar panels similar to those found on residential rooftops and mount them on the ground in huge arrays. (Thin-film solar panels are made by depositing layers of photovoltaic materials on glass or flexible materials.)

“In terms of construction, photovoltaic tends to have a much faster development and construction track,” Roy Kuga, PG&E’s vice president for energy supply, told Green Wombat. “There is a segment of mid-sized projects – in the two to 20 megawatt size – where PV shows a distinct advantage in that market. There’s a huge potential for the PV market to expand.”

That’s good news for companies like First Solar – the Tempe, Ariz.-based company backed by the Walton family that is often called the Google of solar for its stock price and market prowess – and SunPower (SPWRA), the Silicon Valley solar cell maker that’s moved into the power plant-building business.

The speed at which the Sempra-First Solar project went online owes much to the fact that it was built on the site of an existing fossil fuel power plant. “It was already permitted for power generation, transmission existed and it did not have to go through the laborious California permitting process,” says Reese Tisdale, a solar analyst with Emerging Energy Research. “As such, First Solar was able to essentially plug and play.”

Nathaniel Bullard, a solar analyst with New Energy Finance, says he expects utilities increasingly to bet on smaller-scale photovoltaic farms to help meet state mandates to obtain a growing percentage of their electricity from renewable sources. Just this week, PG&E CEO Peter Darbee said his utility plans to invest in solar power plant projects rather than just buy the power they produce.

“I think a utility could easily integrate, technically and financially, 100 megawatts of PV,” Bullard says.  If something is falling behind on your big solar thermal projects, you can plug in PV. I think you’ll see more of this with California utilities and I expect to see it more in Florida and North Carolina. It’s a great runaround to issues of siting and transmission.”

That’s because in California photovoltaic power plants do not need approval from the California Energy Commission. And smaller-scale plants take up far less land and can be built close to existing transmission lines. Most large solar thermal power plants typically are planned for the Mojave Desert and require the construction of expensive power lines to connect them to the grid.

The modular nature of PV solar farms means they can begin generating electricity as each segment is completed while a solar thermal plant only goes online once the entire project is finished.

“Certainly there is a sweet spot in which the project is large enough to gain advantages of scale,” says Tisdale. “Also, these small-to-mid-size systems can be spread about a transmission network, instead of at one site.”

Fifty-four billion dollars is nothing to sneeze at, of course. That’s the amount in the $825 billion economic stimulus package –  introduced by House Democrats Thursday – set aside for renewable energy, electric car batteries, energy efficiency and other green projects.

It’s a start, but that’s less than 7% of the entire stimulus package (or, about enough to pay for the Iraq war for five months, or somewhat more than what the federal government is spending to bail out Bank of America). The lion’s share of the cash is devoted to smart grid technology and transmission lines, with a second big chunk going toward energy efficiency retrofits of public housing and weatherization of low-income homes.

That’s good news for a host of startups developing smart grid technology. But the the bill does not address the most pressing issue facing renewable energy companies today: the credit crunch has dried up financing just as billions are needed to fund factories and the construction of solar power plants and wind farms that will be connected to smart grids and new transmission lines. In recent weeks, layoffs have hit the solar industry. OptiSolar – a Bay Area thin-film solar startup that’s building a 550-megawatt photovoltaic power plant to supply electricity to utility PG&E (PCG) – reported to have furloughed half its workforce. And according to The Oregonian newspaper,  SpectraWatt, a solar cell maker spun off from chip giant Intel (INTC) last year, has shelved plans for a factory in Hillsboro, Ore.  Friday morning, Kate Galbraith at The New York Times’ Green Inc. blog reported that layoffs have now hit the wind industry.

The retrenchment comes as utilities are counting on solar power plants and wind farms to come online in the next two years to help them meet mandates to obtain a growing percentage of the electricity they sell from renewable sources. In California, for instance, PG&E, Southern California Edison (EIX) and San Diego Gas & Electric (SRE) have signed more than four gigawatts’ worth of contracts for electricity to be produced by large-scale solar power stations that will cost billions to build.

Solar startups rely on a provision that allows them to take a 30% tax credit on the cost of building a power plant. Now most of these companies are startups and have no way to use those tax credits as they’re not profitable. Instead, a solar company must essentially trade the tax credits to a firm that can use them in exchange for cash to finance construction. But investors in these deals have all but disappeared as the financial crisis takes its toll. Which is why solar and wind lobbyists are pushing Congress to make the tax credits “refundable” – meaning those companies that don’t have tax liabilities can trade the credits for cash that can be used to finance power plants. “Due to the recession, projects are now being put on hold, factories are closing and workers face potential layoffs unless Congress refines the tax credits now so they work as originally intended,” said Solar Energy Industries Association CEO Rhone Resch in a statement.

The stimulus package unveiled Thursday undoubtedly will be subject to change, but as written it will boost efforts to modernize and digitize the United States’ aging analog power grid. The bill includes:

  • $11 billion for smart grid research and development, pilot projects and the construction of new transmission lines to connect green energy power plants to the power grid. The government will fund 50% of the cost of utilities’ smart grid investments.
  • $8 billion in loan guarantees for renewable energy transmission projects.
  • $6.9 billion in grants to state and local governments for energy efficiency and carbon reduction programs.
  • $6.7 billion for renovation of federal buildings, of which $6 billion must be used for energy efficiency retrofits.
  • $6.2 billion for home weatherization programs for low-income families.
  • $2.5 billion for energy efficiency retrofits of public housing.
  • $2.4 billion for carbon sequestration – so-called clean coal – demonstration projects.
  • $2 billion for energy efficiency and renewable energy research (which includes $800 million for biomass and $400 million for geothermal research).
  • $2 billion in loan guarantees and grants for advanced vehicle battery research.

The smart grid billions will be a boon to companies like Silver Spring Networks, Gridpoint and eMeter that develop software to allow utilities to monitor and manage electricity use in real-time and provide that data to their customers.  “We think 2009 is going to be a good year for us,” eMeter president Larsh M. Johnson told Green Wombat last month. “We’ve seen continued demand from utilities for our services.”

But the billions for the smart grid can be considered a down payment: According to an estimate by research firm New Energy Finance, the price tag for modernizing the power grid over the next 15 years will be $450 billion.

Amid the daily drumbeat of mass layoffs, here’s some sunny news: Solar startup Suniva cut the ribbon Thursday on a photovoltaic cell factory outside Atlanta.

As solar factories go, Suniva’s plant – the first such facility in the Southeast – is relatively small, making 32 megawatts of solar cells annually until  production is fully ramped up to 175 megawatts in 2010. But the factory will create 100 green collar jobs and it follows the opening of  SolarWorld’s new solar cell fab outside Portland, Ore., that will  produce 500 megawatts’ worth of solar cells, and thin-film solar startup HelioVolt’s factory in Austin. Meanwhile, Solyndra, a Silicon Valley thin-film solar startup, is expanding its production facilities while Bay Area rival OptiSolar is building a Sacramento factory that will employ 1,000 workers to produce solar cells for the power plant the company is building for utility PG&E (PCG). (Leading thin-film solar company First Solar (FSLR) operates a factory in Ohio as well as plants in Malaysia.) But Chinese solar giant Suntech (STP) last week said it has put plans for U.S. factories on hold due to the credit crunch.

The Suniva grand opening comes on a good news-bad news day for the solar industry. On one hand, President-elect Barack Obama is expected to nominate alternative energy proponent and Nobel laureate Steven Chu, director of the Lawrence Berkeley National Laboratory, as Secretary of Energy. But the solar industry faces a tough year ahead. On Thursday, research firm New Energy Finance, echoing other analysts, predicted prices for polysilicon – the base material of conventional solar cells – would fall 30% in 2009. That’s bad news for conventional solar cell makers like SunPower (SPWRA) and Suntech if they’ve locked in silicon supplies at higher prices but provides an opening for further growth for thin-film solar companies that make solar cells that use little or no polysilicon.

“We expect to see significant drops in the price of modules next year,” wrote New Energy Finance CEO Michael Liebreich.  “Any manufacturer who does not have access to cheap silicon and who has not focused on manufacturing costs is going to be in trouble. The big shake-out is about to begin. The next two years will change the economics of PV electricity out of recognition.”
