CASSANDRA SWEET, Dow Jones Newswires, November 20, 2009

California regulators have proposed approving a long-term contract between PG&E and Solaren, developers of a speculative technology that would beam 200 megawatts of solar power to earth from outer space.

Under the 15-year contract, Solaren Corp., of Manhattan Beach, Calif., would ship 850 gigawatt-hours of solar power a year starting in 2016, doubling that amount in later years. The power would be sent by radio frequency from an earth-orbiting satellite to a receiving station in Fresno, California. The energy-conversion technology has been used by communications satellites for 45 years on a much smaller scale, Solaren said.

PG&E wouldn’t disclose the cost of the proposed 15-year contract but said it would be above-market, more than 12.9 cents a kilowatt-hour, according to documents filed with the California Public Utilities Commission, or CPUC.

PG&E among other California utilities are required to use renewable sources for a fifth of the power they sell by 2010, ramping up to one-third of their retail power by 2020. The requirements are part of the state’s 2006 plan to combat climate change.

Because Solaren’s technology is untested, raising “concerns regarding the viability of the project,” PG&E can’t rely on the contract to comply with its renewable energy requirements until construction begins on the project and the CPUC gives additional approval, the agency said in a proposed decision.

The CPUC could make a decision as early as December 3, 2009.

space-solar-energy-jj-001San Francisco — PG&E has begun exploring renewable energy from space as it seeks approval from California state regulators, the CPUC, to purchase power from Solaren Corporation offering 200 megawatts over 15 years.

Solaren’s technology uses solar panels in Earth orbit, converting the energy to radio frequency for transmission to an Earth-based receiving station. The received radio frequency is converted into electricity and fed into the power grid. 

Solaren envisions deploying a solar array into space to beam an average of 850 gigawatt hours the first year of the term and 1,700 gigawatts per year over the remaining term according to their filing to the CPUC.

A clear advantage of solar in space is efficiency. From space, solar energy is converted into radio frequency waves, which are then beamed to Earth. The conversion rate of the RF waves to electricity is in the area of 90%, said Solaren CEO Gary Spirnak, citing U.S. government research. The conversion rate for a typical Earth-bound nuclear or coal-fired plant, meanwhile, is in the area of 33%. And space solar arrays are also 8-10 times more efficient than terrestrial solar arrays as there’s no atmospheric or cloud interference, no loss of sun at night and no seasons.

So space solar energy is a baseload resource, as opposed to Earth-based intermittent sources of solar power. Spirnak claims that space real estate is still free although hard to reach. Solaren seeks only land only for an Earth-based energy receiving station and may locate the station near existing transmission lines, greatly reducing costs.

While the concept of space solar power makes sense on white boards, making it all work affordably is a major challenge. Solar energy from space have a long history of research to draw upon. The U.S. Department of Energy and NASA began seriously studying the concept of solar power satellites in the 1970s, followed by a major “fresh look” in the Clinton administration.

The closest comparison to the proposed Fresno, California deployment is DirecTV, the satellite TV provider, Spirnak explained. DirecTV sends TV signals down to earth on solar-powered RF waves. However, when they reach the Earth, the solar energy is wasted, he said, as all the receivers pick up is the TV programming. 

Solaren claims they’ll be working with citizen groups and government agencies to support the project’s development. Solaren is required to get  all necessary permits and approvals from federal, state and local agencies.

At onset, in exploring space solar energy as in exploring all nascent technologies, explorers shall have to show and prove their renewable technology safe.

Publisher’s Note:  Feb 09, 2009 – Not only has Finavera surrendered their Makah Bay license noted below, they also announced surrendering the Humboldt County, California Preliminary Permit to explore wave energy:

“Finavera Renewables has filed applications to surrender its Federal Energy Regulatory Commission license for the Makah Bay Wave Energy Pilot Project in Washington and the Humboldt County Preliminary Permit for a proposed wave energy project in California.”

MendoCoastCurrent readers may recall Finavera’s inability to secure CPUC funding for the Humboldt project; noted below capitalization, financial climate as key reasons in these actions.

MendoCoastCurrent, February 6, 2009

finavera-wavepark-graphicToday Finavera Renewables surrendered their Federal Energy Regulatory Commission (FERC) Makah Bay, Washington wave energy project license, commenting that the Makah Bay Finavera project “never emerged from the planning stages.”

And “due to the current economic climate and the restrictions on capital necessary to continue development of this early-stage experimental Project, the Project has become uneconomic.  Efforts by Finavera to transfer the license were not successful.  Therefore, Finavera respectfully requests that the <FERC> Commission allow it to surrender its license for the Project. ”

Back in early 2007, Finavera’s Makah Bay project looked like it would become the first U.S. and west coast project deployment of wave energy devices.  And this project also had a unique status based on Native American Indian land/coastal waters, so the rules of FERC, MMS were different due to sovereign status.

Then AquaBuoy, Finavera’s premier wave energy device, sank off the Oregon coast due to a bilge pump failure in late October 2007.  

Recently noted was Finavera’s comment that they are currently focusing their renewable energy efforts toward wind energy projects closer to their homebase in British Columbia, Canada and in Ireland.

Editors Note:  On May 11, 2009, PG&E pulled-out of Mendocino WaveConnect, read it here: http://tinyurl.com/qwlbg6 . The remains of the $6M are now solely allocated to Humboldt WaveConnect.

MendoCoastCurrent, January 29, 2009

wave-ocean-blue-sea-water-white-foam-photoPG&E caught a major renewable energy wave today as the California Public Utilities Commission approved $4.8 million in funding their centerpiece wave energy project, WaveConnect. The program also received an additional $1.2 million in matching funds from the Department of Energy. PG&E’s WaveConnect, a project already two years in the making, launches with a $6M kitty.

WaveConnect is chartered with exploring wave energy development off the coasts of Mendocino and Humboldt counties in Northern California. The stakeholders in this region are dyed-in-the-wool political activists, living in environmentally-centric coastal communities and have reacted protectively, sounding alarms that PG&E and the Federal government’s wave energy plans may foul, diminish and destroy the Pacific Ocean and marine life.

Over the two years that PG&E and the Federal Energy Regulatory Commission (FERC) advanced WaveConnect, only recently have environmental concerns and study become part of the discussion. The opportunity for Mendocino and Humboldt coastal communities and local governments to embrace wave energy development and connect with WaveConnect has not gone well, especially as the Federal Energy Regulatory Commission (FERC) has disallowed the City of Fort Bragg and local fishermen to be party in the WaveConnect FERC Preliminary Permitting.

Jonathan Marshall, publisher of Next100, a PG&E blog, wrote “PG&E’s first step will be to conduct meetings with local stakeholders and agencies to learn about their issues and concerns. After completing appropriate environmental reviews and permit applications, which could take a couple of years, PG&E then plans to build an undersea infrastructure, including power transmission cables, to support wave energy demonstration projects. The utility will then invite manufacturers of wave energy devices to install them offshore for testing and comparison.”

“The anticipated cost of wave power compares favorably to the early days of solar and wind,” says William Toman, WaveConnect project manager at PG&E. “It will take several stages of design evolution to lower costs and increase reliability.” The CPUC and the DOE are betting on this evolution as in this funding scenario engineered by PG&E, the CPUC awards $4.8M in ratepayer funds while the DOE $1.2M is a matching grant.

Wave energy may become a key source of renewable energy in California. It’s proposed that the 745-mile coastline could produce 1/5th of California’s energy needs if, admittedly a big if, economic, environmental, land use and grid connection issues — and community issues — don’t stand in the way.

Marshall wrote in closing “Making ocean power technology work reliably and at a competitive price will be the first big challenge. Serving offshore installations with power transmission lines will be another economic and engineering hurdle. Finally, ocean power developers must also convince local communities and government regulators that their installations will not destroy marine life, cause boating collisions or navigational hazards, or degrade ocean views.”

FRANK HARTZELL’s article with MendoCoastCurrent edits, January 15, 2009

After nearly two years of local pleas for specifics on the WaveConnect project, PG&E representatives surprised Fort Bragg and Mendocino County representatives with many new details.

Those included the promise by PG&E that all environmental studies would be public, not private information. In the recent past, PG&E had been resisting calls by competitors and ratepayer advocates before the California Public Utilities Commission to make public more information learned during the WaveConnect study.

Another surprise was that PG&E has found about 10 different viable wave energy technologies — far more than first envisioned. The utility will choose the top three or four wave energy devices and test those under a pilot project license.

On Tuesday, the pilot license process became the biggest issue for wave energy officials gathered at Town Hall to hear two top officials explain the roles of the Federal Energy Regulatory Commission, or FERC, and the California Coastal Commission.

Both Tom Luster, who will oversee all wave energy projects for the California Coastal Commission and 23-year FERC veteran Ann Miles, FERC Director of Hydropower Licensing said Fort Bragg has had more interest in wave energy than anywhere else in California.

Miles said PG&E would need to file for a conventional license by this March under FERC rules. Using the “faster” pilot license gives them until March 2010 to get started.

Miles provided lengthy and knowledgeable explanations of convoluted FERC processes during the three-hour meeting. But PG&E’s new announcements, which came in private meetings last week, overshadowed the presentations by the top state and federal officials.

Luster explained how the California Coastal Commission would work with the State Lands Commission to review any wave energy project within three miles of shore.

PG&E is now saying their 40-megawatt powerplant will be located “well beyond” that three-mile state limit. The powerplant would likely come after the five-year pilot project license.

That announcement unexpectedly changed the game for the state.

Luster said the big power cable that extends to shore would be regulated by the Coastal Commission, but development beyond three miles would be regulated only for “federal consistency.”

While planning for an eventual project many miles from shore, PG&E will give up on areas more than three miles from shore for now, they have told FERC.

PG&E told Fort Bragg they would site the pilot project much closer to shore, to avoid the jurisdictional conflict between FERC and fellow federal agency Minerals Management Service, or MMS.

FERC claims the authority to be the regulatory authority for all water energy projects in the United States. MMS claims authority for ocean federal waters, which are those more than three miles from shore.

PG&E’s 68-square-mile preliminary permit area, which runs from Point Cabrillo to Cleone and to more than three miles offshore, will be trimmed down to eliminate areas beyond the federal-state jurisdiction line.

PG&E representatives are now promising significant help to local governments.

It was reported that all of the power generated by the 40 megawatt WaveConnect would be consumed in Mendocino County and would provide for nearly all of Fort Bragg’s electric demand when WaveConnect is generating.

Additionally, PG&E intends to pay their expenses, including reviewing, permitting and the community process for public participation.

Miles said FERC has no requirements in place to determine that a developer be able to pay for removal of devices in case of bankruptcy or disaster.

Luster said the State Lands Commission handles financial arrangements, such as bonding of projects.

Miles was making her first ever visit to Northern California. She was set to answer questions from the general public at a Town Hall forum Tuesday night.

MARIA DICKERSON, the Los Angeles Times, December 27, 2008

7nov07_solarAt a time when many investors are sticking money in their mattresses, Californians are putting it on their roofs.

Applications for state rebates to install solar panels hit their highest level ever in December, one of the few bright spots in an otherwise gloomy economy.

Residents filed a record 1,215 applications seeking solar subsidies this month, according to the California Public Utilities Commission. That’s the best showing in the program’s 24-month history, and December isn’t even finished. More than 18,000 California homeowners and businesses have applied for rebates over the last two years. Although not everyone who files this paperwork actually ends up installing solar, the figures are viewed as a reliable barometer of future demand.

A record 133 megawatts of solar photovoltaics have been installed in California so far this year, even as the state’s economy has stumbled.

Michelle Gerdes of Long Beach just lost her job as a designer for a dinnerware manufacturer. Her husband, Steve, works for an air-conditioning company whose business is slowing. But that didn’t stop the couple from buying $32,000 worth of photovoltaic panels that went up on their roof this month. The state rebate and a federal tax credit will reduce their out-of-pocket costs to about $17,000 — a substantial saving but still a big chunk of change. “We decided to just go for it,” said Michelle Gerdes, 44. “It’s the right thing to do for the environment . . . and it will definitely increase the value of our house.”

Coming in the midst of a deep recession, continued strong demand for solar has thrilled — and puzzled — officials who oversee the California Solar Initiative, which seeks to put panels on 1 million roofs in California within a decade. Consumers nationwide are in a serious spending funk. Even with California’s generous incentives, photovoltaic systems can cost tens of thousands of dollars.

New federal tax breaks have persuaded some homeowners to take the plunge, said Molly Sterkel, who manages rooftop solar efforts for the utilities commission.

Others are being enticed by new financing models pioneered in California that allow them to go solar for little or no money down. Add rising electricity rates in many parts of the state and turmoil in the financial markets, and some consumers are concluding that sunshine is their safest investment.

California is by far the nation’s leader in rooftop solar, with well over half the installed capacity.

“In an economic downturn, people are looking for ways to save money on things that they are going to do anyway,” said Nat Kreamer, founder of SunRun Inc., a San Francisco residential solar energy company. “Electricity is one of those fundamentals.”

Launched in January 2007, the California Solar Initiative is an attempt to push photovoltaics on a mass scale in California to help cut greenhouse gas emissions and shore up the state’s energy supply.

The goal is 3,000 megawatts installed by 2018, enough to displace five good-sized power plants.

Funded by utility ratepayers across the state, the $3-billion program offers rebates to Californians who install panels on their homes and businesses. Incentives vary. But refunds typically range from 20% to 50% of a system’s cost.

The incentives are structured to decline over time as demand grows, meaning Californians who act sooner will get the biggest refunds.

Rooftop solar will get even more attractive in January. Congress recently expanded federal investment tax credits for residential solar arrays. Starting next year, homeowners will be eligible for tax breaks of up to 30% of the entire cost of their projects. Those benefits had previously been capped at $2,000 per system.

“That has really spurred the market,” said Lyndon Rive, chief executive of SolarCity, a Foster City, Calif.-based solar installer. “Our cash sales have increased dramatically.”

For consumers who still can’t afford to purchase, SolarCity has a residential leasing option. It lets them put solar on their roofs without the hefty upfront costs. Customers cut their power bills while the rebates and tax credits flow to SolarCity, which maintains ownership of the panels.

The deal has proved so popular that it has turned SolarCity into the state’s largest installer of residential rooftop photovoltaics.

Kreamer’s SunRun offers a similar program known as a power purchase agreement. His company installs, maintains and owns the systems. Homeowners sign a long-term contract with SunRun for solar energy that’s priced below what they pay for conventional power.

Californians pay some of the highest electricity rates in the country. Rates in many parts of the state are rising.

The Gerdeses’ utility, Southern California Edison, is asking state regulators to allow it to collect more than $700 million extra from its ratepayers next year.

It won’t be coming from the Gerdeses. With solar panels now snug on their roof, the couple needn’t worry about rising electricity bills as the recession deepens.

“We can think about turning the hot tub back on now,” Michelle Gerdes said.

JOHN DRISCOLL, The Times-Standard, December 15, 2008

A white paper commissioned by the state of California says that tapping the ocean for power should be done carefully.

The report for the California Energy Commission and the Ocean Protection Council looked at the possible socio-economic and environmental effects of the infant industry, including what it might mean for fisheries and coastal habitat.

It also made recommendations on what research should be done to address those potential effects.

The waters remain murky in regard to what type of technology wave energy projects might use, and the scope of necessary development. The study finds that it will be key to fill in that missing information to determine what impacts they might have.

“Site selection and project scale are critical factors in anticipating these potential effects,” the report reads.

Depending on their size and location, the study reads, commercial and sport fisheries might be impacted, but new projects would yield construction and operations jobs for nearby communities.

But projects could also interfere with wave shoaling and beach building by stripping some energy out of waves, and that in turn could affect species from the high tide line out to the continental shelf.

The buoys or other structures designed to convert wave power to electricity are also likely to act like artificial reefs where reef-related fish would congregate, the report reads, a change from what would typically occur in the open ocean.

Birds and marine mammals may also be affected, but likely to a small degree, the study found.

Still, the report concludes that there aren’t any dramatic impacts expected, and recommends that the push to develop projects proceed carefully, listing a slew of research that should be done to help understand the potential for problems.

Greg Crawford, an oceanographer with Humboldt State University and an author of the paper, said that much depends on what type of wave projects are employed.

“This stuff needs to be approached holistically,” Crawford said.

While some wave energy projects are beginning to be used around the world, there is little information on how durable they are over the long term.

As Crawford pointed out, they are deployed in particularly difficult and treacherous environments.

The report recommends starting small, both in the laboratory and with small-scale projects to help begin to understand the effects they might have when deployed on an industrial scale.

The Pacific Gas and Electric Co. has won authorization from the federal government to study several areas off the Humboldt and Mendocino coasts, but the company recently ran into what appears to be an insurmountable obstacle from state utilities regulators on another project off Trinidad. In October, the California Public Utilities Commission denied the first wave power project it has ever considered, on the grounds that the Trinidad Head proposal isn’t viable, and the contract price to sell the power is too expensive.

A feud of sorts over final jurisdiction on wave energy projects persists between the Federal Energy Regulatory Commission (FERC) and the U.S. Mines and Minerals Service (MMS). And it’s not clear exactly what agency would make the determination of whether the costs of projects outweigh their benefits, said HSU economist Steve Hackett, another author of the study.

“I think it’s a very daunting situation for the public utilities or a power company to take on,” Hackett said.

While environmental issues will be hashed out in an environmental analysis, economic effects should also be considered, Hackett said. That includes the detriments to a struggling fishing fleet and the upside of jobs from energy projects, he said.
