CEC Requesting Reliability Data from Tessera Solar

The California Energy Commission (CEC) requested that Tessera Solar LLC submit detailed logs on the reliability of its "Suncatcher" solar technology,  potentially reflecting doubt about the effectiveness of the company's proposals.  According to transcripts of a 20 September CEC hearing, the CEC Staff believed that Tessera Solar should be required to submit reliability data in order to be allowed to proceed with its Imperial Valley Solar project, which is proposed for over 6,000 acres of California Desert habitat.   Tessera Solar is the same company that is also proposing to bulldoze another 4,600 acres of the Mojave Desert for the Calico Solar power project.

Both the Calico Solar and Imperial Valley Solar projects would utilize the "Suncatcher" technology.  Each Suncatcher resembles a giant satellite dish that would harness solar energy.  This technology is not as tested as parabolic technology selected for other solar projects since the Suncatchers involve more working parts in order to rotate and track the path of the sun during the day, making them prone to a potentially higher rate of failure.   Additionally, the Suncatcher technology is very loud, and placing thousands of the dishes on the Calico and Imperial sites would be disruptive to the quiet solitude for miles around the sites.  For the Imperial Valley project, a nearby location could have ambient noise increased by 19 decibels, according to a CEC Staff Assessment.

The fact that the CEC Staff requested data on the reliability of the Suncatchers and have gone so far as to include this as a condition necessary to the approval of Tessera Solar's Imperial site suggests the concerns have caught the attention of Sacramento.  It would be a tremendous waste if Tessera Solar's projects fail after it receives approval to bulldoze thousands of acres of prime desert wilderness on public land, using taxpayer money (in the form of American Reinvestment and Recovery Act funds).

    Bulldoze? Please do some research....

    sorry Anonymous...I forgot that there is a miraculous way of placing thousands of Suncatchers in desert habitat without degrading the quality of vegetation and killing wildlife. Please enlighten me on this wonder.

How Many Plants Species in the Desert?

Would you expect that California's desert hosts gives the redwood forest a run for its money when it comes to plant biodiversity?  It's easy to take the desert for granted when all you want to do is zoom through it on the highway and get to your destination. But you are passing by an amazing and biologically diverse ecosystem.  There are at least 2,450 native plant species found in California's desert, according to a great article by Chris Clarke on desert life , posted at KCET. If you want to learn more about our amazing deserts, join Desert Biodiversity, a new organization dedicated to exploring, respecting and defending the deserts.

Mowing Vegetation as Mitigation: Trump Administration Practice Goes Unchallenged

Image
The Trump administration is again touting the practice of mowing thousands of acres of desert vegetation as environmentally-responsible, despite a preponderance of evidence to the contrary.  The draft environmental review of the Yellow Pine Solar project in southern Nevada claims that vegetation mowing - as opposed to bulldozing - will yield positive outcomes that are highly doubtful.   This positive framing of the construction practice misleads the public and decisionmakers and ignores decades of scientific research regarding the impacts of mechanized disturbance on desert wildlands.  According to the draft environmental review: "Mowing is becoming the standard on large site-type ROWs to prevent permanent impairment of public lands (as mandated by FLPMA) and in lieu of off-site mitigation... Mowing methods are designed to help preserve soils, biological soil crusts, soil seed banks, native perennial vegetation diversity and structure, and cacti and yucca species, and to resist

The Absurdity of the Cadiz Water Export Scheme

Image
The Department of Interior this month reversed a policy to make it easier for the Cadiz company to pump billions of gallons of water from an ancient Mojave Desert aquifer - killing off natural springs that wildlife depend upon - to ship that water to the lush landscaping of Orange County.   Cadiz still has other hurdles in its way, but the company's tenacity and willingness to line the pockets of politicians could spell doom for Mojave wildlife. Cadiz Calls it Conservation The Cadiz company has a contract to export nearly 16.3 billion gallons (yes, that is billion with a 'b') a year for 50 years from the Mojave to the Santa Margarita Water District ( SMWD ) in Orange County.  The Cadiz company claims that it will only pump water that would otherwise evaporate from a dry lake bed and that the aquifer will naturally recharge from rainfall, leaving no significant impacts on wildlife or groundwater levels.  According to Cadiz propaganda, this isn't a water export sche
