Solar Ranch pros and cons

The devil is in the details in Los Angeles Department of Power and Water’s 1200 acre Southern Owens Valley Solar Ranch proposal. This post is about a few of the tidbits not included in the DEIR (I, II, & III) or that the consultants have blatantly come to the wrong conclusion about.

Don’t get me wrong, I’m a huge fan of utility scale solar power like this project, BUT only when it is done in the right place and is actually Designed (with a big D) by folks like landscape architectures – not just engineered with no poetry like DWP seems to be doing.

Scenic impact

The proximity to Manzanar National Historic Site is the biggest boondoggle and the source of most opposition. There will be SUBSTANTIAL impacts on ‘scenic vistas’ no mater where the project is built (topic AE-1, AE-3 & AE-4). The viewshed analysis from Manzanar and 395 are pretty sloppy – note how the parking lot dominates the foreground. This isn’t the view that most visitors will be offended by.

Plus this part of the Owens Valley has great dark skies with minimal artificial lights near by – the solar ranch will substantially damage one of my favorite star gazing locations even if they try to limit light trespass.

Water

Biggest environmental issue is the impact of pumping an additional 10 acre-feet of groundwater to clean the photovoltaic panels. So how much water will be needed during construction for the concrete foundations and to control dust???

Alternative sites

To equal the 200mw capacity of the Solar Ranch, it would take just 20,000 – 40,000 residential installations at 5-10kw each. Since there are 665,992 single family houses in LA per the census, this just means that 17% of houses need to install solar panels to replace the Solar Ranch.
-Or-
The 1200 acres ‘needed’ by DWP can easily be found around Los Angeles on city owned property (for example, the Whitnall Highway R.O.W is about 120 acres)

So the statement that distributed PVs are ‘Infeasible under existing power system operational capabilities without compromising system integrity and safety’ is to kindly state, BS.

Looking at the insolation aka how cloudy it is, the Owens Valley has pristine blue skies about 25% of the time. Okay, this is using weather data for Bishop which is the nearest NOAA weather station, not for the region near Independence/Manzanar.

ARID Journal & Aqueduct Futures

For this November’s centennial of the LA Aqueduct, two journals (ARID and BOOM) have special issues that are really cool read for infrastructure and landscape folks. Included in ARID are two articles using data collected as part of the Aqueduct Futures project!

Barry J. Lehrman, Douglas Delgado and Mary E. Alm, Ph.D.  Aqueduct as Muse: Educating Designers for Multifunctional Landscapes

Lee-Anne Milburn, Ph.D. and Barry Lehrman, with Tiernan Doyle, Eric Haley, James Powell and Devon Santy.  Contested Waters, Unholy Alliances, and Globalized Colonies: Exploring the Perception of Water by Residents of the Los Angeles Aqueduct Watershed

Grant Lake, (c) Eric Haley 2012

On a personal note, ARID Journal also includes my dedication to my late wife, Mary Alm who died after a 15 month fight with cancer in September. I am deeply grateful for the opportunity to write ‘Aqueduct as Muse’ with her.

Mary Alm, PhD 1969-2013

Mary Alm (1969-2013) was my muse, dear wife of nine years and mother of our son. She died peacefully after a grueling 15-month fight with breast cancer, just days after we submitted the final manuscript to Arid. The week before she was stricken by an undetected metastasis, I was finally able to bring her up to the Owens Valley to see the place that is now the foundation of my academic career.

As the cool and calmly collected presence reigning in my boundless ideas, Mary Alm brought focus to my life and provided the inspiration that encouraged me to aim for the moon.

As a health psychologist, Mary gave me a perspective into human behavior that enriched my scholarship into urban landscape systems and sustainability. This article was our first published collaboration to connect the gulf between our disciplines. Writing together—often at her weekly infusions during the darkness brought by the cancer—gave us strength to persevere against the relentless toll chemotherapy inflicted and to continue to pursue our dreams of future endeavors together.

As a lasting tribute to our love, this article is dedicated to Mary’s genius, goodness, and grace.

Resilience on my mind

There are days that I feel like a rubber band – being stretched in so many different directions. Then I snap back. That is resilience.

Climate resilience is such a seductive concept like regeneration that it is one of the primary topics I teach. But not sure if we actually have the political and economic means to pull it off (nor does Andrew Revkin). Check out the video [which refuses to be embeded] of Revkin’s recent appearance at Zócalo Public Square that focused on the topic.

So what am I doing to shift the status quo? Getting stretched in all sorts of ways organizing a symposium for the LA Aqueduct Centennial with folks from UCLA (including Alex Hall and Jon Christensen who are in the video), Woodbury’s Arid Lands Institute, and my mentor Lance Neckar at Pitzer. Target date winter 2014 if we line up the funding. Stay tuned!

A quick shout out to Dan Hill for a fascinating read about the ‘Urban Intelligence Industrial Complex’ aka the ‘Smart City’ movement…

There is a remarkable amount of intact vegetation beneath the heliostats – making me wonder if it is possible to design a low-impact solar farm?

Ghosts of NAWAPA

Cross posted from the aqueductfutures blog

The Bureau of Reclamation is proposing a massive uphill diversion from the Missouri River to Denver. The Missouri River Reuse Project [pdf] would provide 600,000 Acre-Feet of water to the Front Range to as an alternative to desiccating the Upper Colorado even more.  This evokes the ghost of the continental engineering of North American Water and Power Alliance (1964) or towing icebergs from Alaska to provide water to Los Angeles.

“The idea of constructing conveyances to move water resources between other basins and the Colorado has been raised before and was once again submitted as an idea in this process,” Bureau of Reclamation public affairs chief Dan DuBray said in a statement. “Any proposal will be evaluated for feasibility, broad support and realistic funding potential before further consideration would be given.” – The Denver Post

The dark side of solar

The math isn’t adding up for the local economics of solar farms as reported by the LAtimes.

BrightSource Energy’s $2.7-billion Hidden Hills solar power plant in Inyo County was  first estimated to boost the County;s general fund 17%. But this didn’t factor in the federal solar tax exclusion on property. Fewer than 10 local workers get permanent jobs — just 5% of the construction jobs would be filled by county residents, who are likely to spend their money in Nevada – not Inyo County’s population center in Owens Valley. Improvements to public infrastructure like roads would cost the county $11 million to $12 million. Then in perpetuity would be  nearly $2 million a year in additional public safety and other services paid by tax payers. This reality contrasts with the rosy picture painted by Oakland-based BrightSource Energy, who promised 1,000 construction jobs and 100 permanent positions, generating wages of nearly $550 million over the life of the project contributing more than $300 million in local and state tax revenues. Not much discussion of the ecological side in the article beyond the expected higher property values and decreased public access to land as habitat mitigation areas are cordoned off.

“We’ve got county residents living in cargo containers near the solar site, seniors living in trailer parks on fixed incomes — they all manage to pay their 1% property tax fee,” said Kevin Carunchio, the county’s administrative official. “Nobody is outright against these projects on ideological grounds or land-use principles. We don’t think we should have to bear the cost for energy that is being exported to metropolitan areas.”

Then there is the visual impacts:

“Residents will live as close as 600 feet from a heliostat field replete with approximately 170,000 mirrors encircling two 750-foot towers as their neighbor.”

BrightSource maintained that the power plant would not create a significant visual impact. Instead the project has been pitched as a potential tourist attraction, with its twin 70-story towers envisioned as a magnet drawing sightseers to the Pahrump Valley.

Carunchio — who is open to most plans to bring attention to the region — is skeptical.

“I can’t believe that people will drive the long way to Death Valley just to look at the Eye of Mordor,” he said.

Elsewhere in the Mojave:

“Southern California is going to become the home to the state’s ability to meet its solar goals,” said Gerry Newcombe, public works director for San Bernardino County. “That’s great, but where are the benefits to the county?”

in San Bernadino County, the $2.2-billion Ivanpah solar project will be proving a $377,000 annual payment to the county in lieu of taxes. This doesn’t cover the public safety costs.

Gov. Jerry Brown has vowed to “crush” opponents of solar projects. At the launch of a solar farm near Sacramento, the governor pledged: “It’s not easy. There are gonna be screw-ups. There are gonna be bankruptcies. There’ll be indictments and there’ll be deaths. But we’re gonna keep going — and nothing’s gonna stop me.” …

“The solar companies are the beneficiaries of huge government loans, tax credits and, most critically for me, property tax exemptions, at the expense of taxpayers,” said [Riverside] county Supervisor John Benoit, referring to a variety of taxpayer-supported loans and grants available to large solar projects as part of the Obama administration’s renewable energy initiative. “I came to the conclusion that my taxpayers need to get something back.”

Solar development isn’t looking as bright as it was – but just contrast this with permanent destruction of groundwater, nearby resident’s health, and green house gas emissions of fracking and the negative impacts of solar still make it the best energy source (other than conservation) we have.  The best place for solar is on roofs and disturbed lands – not intact desert habitat There is a place for large utility scale solar energy development, but it needs to be done wisely, not quickly.
