Environmental group sues to stop solar project

Riverside Press-Enterprise - Environmental group sues to stop solar project

By David Danelski, Jan 20

An environmental group has filed a lawsuit contending the federal government's "fast track" approval of a solar energy development -- already under construction in northeast San Bernardino County -- violated several laws.

The Western Watersheds Project, which works to protect watershed areas in six western states, wants a federal court to rescind the approvals and halt construction.

The complaint, filed Friday, names as defendants the U.S. Bureau of Land Management, the U.S. Fish and Wildlife Service, Interior Secretary Ken Salazar and other federal officials.

BrightSource Energy Co. broke ground in October on the 5.6-square-mile solar field in the Ivanpah Valley off Interstate 15 near Primm, Nev. The project was approved in an expedited process intended to help energy developers meet federal deadlines to qualify for stimulus subsidies.

BrightSource, based in Oakland, plans to focus heat from thousands of mirrors onto three "power towers" to generate steam and run turbines that would produce enough electricity for as many as 140,000 homes. The project is on public land controlled by the BLM.

"This project was just rushed," said Michael Connor, California director for Western Watersheds Project. "It was a rush to judgment. They had already decided they were going to build these things."

Lois Grunwald, a Ventura-based Fish and Wildlife spokeswoman, said she had not seen the complaint and could not comment on it. BLM officials also had no comment, spokesman David Briery said.

A BrightSource spokesman said in an e-mail that the company "does not comment on legal matters pertaining to governing bodies that regulate our industry."

The watershed group says the federal agencies cut corners on environmental reviews, violating the National Environment Policy Act and the Endangered Species Act, among other laws.

Among several allegations, the group accuses the government of inadequate reviews of alternatives, such as allowing BrightSource to build on nearby Ivanpah Dry Lake, which has little or no habitat value for desert tortoises, a species threatened with extinction, and other wildlife. The lawsuit says 30 tortoises have been found at BrightSource's current location.

The government also did not fully analyze how upgrading power lines will affect wildlife, the suit alleges.

The Western Watersheds lawsuit is one of several legal challenges to solar projects that the Obama administration approved last year on public land in the Mojave Desert.

The Sierra Club on Dec. 30 sued the California Energy Commission over its approval last fall of the Calico solar development, planned off Interstate 40 about 37 miles east of Barstow, said Gloria Smith, an attorney for the club. The suit, filed with the California Supreme Court, faults the commission for not detailing how the developer would compensate for lost wildlife habitat.

Also in December, a Native American cultural protection group and tribal members sued the Obama administration over the fast-track approvals of six large solar developments, including Ivanpah and Calico. They contend federal officials violated laws that protect sacred places.

DOE Finalizes $1.45 Billion Loan Guarantee for One of the World's Largest Solar Generation Plants

Department of Energy - DOE Finalizes $1.45 Billion Loan Guarantee for One of the World's Largest Solar Generation Plants

Washington D.C. - U.S. Energy Secretary Steven Chu today announced a $1.45 billion loan guarantee has been finalized for Abengoa Solar Inc.'s Solana project, the world's largest parabolic trough concentrating solar plant. Located near Gila Bend, Arizona, the 250-megawatt (MW) project is the first large-scale solar plant in the United States capable of storing energy it generates. Solana will produce enough energy to serve 70,000 households and will avoid the emissions of 475,000 tons of carbon dioxide per year compared to a natural gas burning power plant.

"As the world's largest solar plant of its kind, the Abengoa's Solana project is playing an important role in creating jobs and clean energy for Arizona as well as fostering innovation in the U.S.," said Secretary Chu. "As today's announcement and other recent announcements of completed loan guarantees for wind and solar projects demonstrate, the Department's loan program is gaining momentum, creating jobs in communities across the country while putting us on the path to a clean energy future."

"I congratulate Abengoa Solar and the administration for developing public-private opportunities that will create well paying, highly valued jobs for Arizona," said U.S. Rep. Raul M. Grijalva. "This is yet another example of stimulus funds helping to lead our nation's and Arizona's economy back to recovery, while transitioning our energy policies to allow us to become a national and world leader in alternative energy generation."

Abengoa Solar Inc., the project sponsor, estimates that the Solana project will create between 1,600 to 1,700 new construction jobs and over 60 permanent jobs. The jobs created by the project will be located in Arizona and in neighboring states. To accommodate the project's need for over 900,000 mirrors, a mirror manufacturing facility will be built outside of Phoenix. As a result, the company anticipates the project will create additional direct investment in Arizona's economy.

U.S. providers and manufacturers will supply 70 percent of Solana's components, such as mirrors, receiver tubes, and the heat transfer fluid. Electricity from the project will be sold through a long-term power purchase agreement with Arizona Public Service Company.

The Department of Energy, through the Loan Programs Office, has issued loan guarantees or offered conditional commitments for loan guarantees to support 16 clean energy projects totaling nearly $16.5 billion. Together, the 16 projects will produce over 37 million megawatt-hours, enough clean energy to power over 3.3 million homes. Additional DOE-supported projects include the world's largest wind farm and a 2,200 MW nuclear power plant - the nation's first in three decades.

Can SolarReserve Top BrightSource? « TechPulse 360

Can SolarReserve Top BrightSource? « TechPulse 360

SolarReserve is one of the few next-generation solar-thermal vendors with field experience.
The company has the exclusive rights to the molten-salt technology United Technologies’ Pratt &Whitney RocketDyne tested at Solar Two in the California desert during the 1990s.
“We consider that to be a strong competitive advantage,” says Tom Georgis, vice president of development.
It also is a critical reason why the Santa Monica company believes its plants will match or top the efficiency of BrightSource’s Ivanpah. And the experience is at the foundation of SolarReserve’s belief it will find financing, despite the reluctance of private lenders.
SolarReserve is among the most promising of a new wave of solar-thermal developers. Instead of replying on parabolic mirrors, like the SEGS operating in the Southwest desert, these entrepreneurs hope to prove technologies just now moving from the drawing board to large scale deployment: ground-mounted heliostats, heat-concentrating towers, high operating temperatures and storage mechanisms, such as molten salt.
The company’s proposed plants (two in the United States and one in Spain) use as many as 17,000 heliostats to reflect sunlight to receivers atop of 653-foot towers. There the sunlight transfers heat to molten salt, warming the sodium and potassium mixture to 1,050 degrees Fahrenheit, after which it is transferred to a storage tank where it loses no more than 1 degree a day. (BrightSource also anticipates more than 1,000-degree temperatures at Ivanpah.) The superheated liquid is channeled to a heat exchanger where it boils water and powers a turbine.
Solar Reserves claims high efficiencies for much of its operations. The transfer of sunlight to heated salt is 88 percent efficient and the storage tank maintains 98 to 99 percent of the thermal efficient of the molten salt. The weak link is the steam generation system: about 39 to 42 percent efficient. Improvements in turbine technology should raise this.
Altogether, a SolarReserve plant will have an efficiency of 18 to 19 percent, says Georgis. This compares favorably to the 18 percent efficiency BrightSource expects at Ivanpah. (The new generation of solar-thermal plant with concentrating towers and heliostats in general should achieve efficiencies of 17 percent to 20 percent, says Electric Power Research Institute Project Manager Cara Libby – well above the 13 to 15 percent of the older trough plants in the Southwest and Spain.)
SolarReserve also expects to rival BrightSource with its capacity factor, a measure of the amount of time a plant can achieve full output.
The California plant, outfitted with a 150-megawatt turbine, is designed to generate peak-period power for PG&E. Running an average of 8.5 hours a day, it should achieve a capacity factor of 34 percent by heating and storing salt in the mornings and using it to deliver power well into the evening.
BrightSource’s 392 megawatt Ivanpah is to have a capacity factor of 30 percent.
SolarReserve’s Nevada plant should do better. It will have a smaller 100-megawatt turbine and operate longer hours, earning a capacity factor of 53 percent. (The longer the operating hours and the smaller the turbine, the higher the capacity factor is likely to go.)
Despite the ability of the SolarReserve facilities to storage energy, the challenge will be finding financing. Without federal loan guarantees, most plants won’t stand a chance. But the company doesn’t appear ready to buy into the theory.
“It is certainly a challenging environment,” agrees Georgis. “But we are confident we will secure financing for our projects.”
SolarReserve has applied for Department of Energy loan guarantees and is quick to defend their role. “Having the DOE loan guarantees makes it easier to finance,” he says. The extensive government due diligence makes private lenders more comfortable and debt cheaper.
That’s why the industry let out a sigh of relief when Abengoa’s Solana plant near Phoenix won $1.45 billion of Energy Department loan guarantees in July – the first granted since BrightSource’s $1.37 billion package in February.
But SolarReserve appears willing to push ahead even without a government award. It hopes to break ground in both California and Nevada by the end of the year.
The company argues that utilities wouldn’t sign power purchase agreements if they didn’t value the power – a key proof-point with banks. It also largely dismisses increasing competition from solar panels.
Panels are easier to finance, quicker to permit and simpler to deploy. They also are less expensive. With the collapse of module pricing last year, panel costs fell to between $3.50 and $5.50 a watt from $6 or more, says Ted Sullivan, senior analyst at Lux Research. Costs of solar thermal remain largely unchanged at $7 to $8 a watt.
Still SolarReserve isn’t deterred. “It’s more competitive now, no question,” concedes Georgis. But “our power plants are not intermittent resources (and) we’re offering competitive pricing.”
So will the new generation of plants be successful? “It’s too early to say,” says Sullivan. “There have been a lot of plans out there, but nothing has been built on that scale.”
With many technologies showing promise, it will be interesting to see who goes first.

Solar Reserve's (spun out of UTI) Molton Salt CSP Technology

Molten Salt Solar Plant

Molten Salt Solar Plant

A Santa Monica-based energy firm known as SolarReserve in association with a rocket maker in Canoga Park is planning to set up a much larger plant in this desert area to power around 100,000 homes. This power plant will consume molten salt, water, sun’s heat and rocket science to generate electricity. SolarReserve have already patented the technology. Engineers from Rocketdyne are instrumental in developing this technology. Terry Murphy who is the president of SolarReserve says, “Molten salt is the secret sauce.” Many technological ideas are being in various state of readiness to be implemented in California. But analysts found molten salt technology as most unusual and at the same time promising idea. Nathaniel Bullard, a solar energy analyst with New Energy Finance in Alexandria, Va, thinks, “It’s actually something we’ll likely see in a few years. It’s moving along in a nice way, and they have good capital behind it.” Last year the company secured $140 million in venture capital.


The biggest advantage of the molten salt is once cooled, it could be reutilized for the same purpose. The molten salt can be stored for days to generate electricity. We know that storage of power is great problem as far as energy generated from alternative sources. We can store power in a battery on a small scale basis such as car or home. But power for such a large scale can’t be stored in batteries. Murphy elaborates on the solution to power storage, “You can put that (molten salt) into a storage tank that would look much like a tank at an oil refinery. We can store that energy almost indefinitely.”
SolarReserve, is providing funds to the venture and doing the marketing of the project. Many environmentalists groups are voicing concern about the amount of water utilized. But SolarReserve officials are sure that the plant would use one-tenth the amount of water required by a conventional plant.

World’s Largest Solar Power Project Planned in India

World’s Largest Solar Power Project Planned

Gujarat, a state of India, is quite eager to opt for alternative sources of energy. It started out as a small dream. The Gujarat government visualized only 500 MW of solar power generation by 2014. But this humble goal may now be increased to 3,000 MW. The Gujarat Government is undertaking a $10 billion project and it will hold the distinction of the world’s largest solar power facility in India. This project will be backed by former U.S. President Bill Clinton. The 3,000oMW project will get aid with logistics and financial support from the William J Clinton Foundation.

The Clinton Climate Initiative which is a part of the foundation will assist in identifying producers of solar thermal equipment.

World Bank to Invest in North African Solar

World Bank to Invest in North African Solar

The World Bank will invest $5.5 billion for North African solar power projects. They have announced that initially World Bank will put in $750 million dollars from the Clean Technology Fund with the remaining amount will be arranged from other sources. World Bank is expecting to complete these projects by 2015. They are willing to include five countries in this project and hoping to triple world wide concentrated solar power technology (CSP) capacity.

Google Plans New Solar Mirror Technology

Google Plans New Solar Mirror Technology

They are developing a new mirror technology for cheaper solar power. Weihl confirms, “Typically what we’re seeing is $2.50 to $4 a watt (for) capital cost. So a 250 megawatt installation would be $600 million to a $1 billion. It’s a lot of money.” That amounts to 12 to 18 cents a kilowatt/hour. They are using solar energy to heat up a substance that produces steam. This steam will turn the wheels of turbines. Mirrors will start the whole process by directing the sun’s rays on the substance to heat it up. Bill Weihl reaffirms his company’s commitment, “We’ve been looking at very unusual materials for the mirrors both for the reflective surface as well as the substrate that the mirror is mounted on.”
