REGION: Irish developer backs desert solar farm
By DAVE DOWNEY - Staff Writer | ∞
An Irish green-energy developer announced Thursday it is investing $100 million and taking controlling interest in Phoenix-based Stirling Energy Systems, which wants to build two of the world's largest solar farms in the Southern California desert.
One of the solar farms would be built in the Imperial Valley, near the Salton Sea. With an initial capacity to generate 300 megawatts and the ability later to produce 900, it is the single largest project San Diego Gas & Electric Co. is counting on to help the utility shift to a greener future.
SDG&E, like California's other major urban utilities, faces a state mandate to deliver 20 percent of its electricity from clean, so-called renewable power by 2010.
SDG&E has said it could deliver the initial 300 megawatts through the existing Southwest Powerlink transmission line through southern San Diego County, but will need the 1,000-megawatt-capacity Sunrise Powerlink proposed for North County to bring in the rest of the power.
"This is a very exciting investment for NTR," said Jim Barry, chief executive for NTR, the international green-energy developer founded in Ireland in 1978, in a prepared statement issued Thursday. "In SES, we have a partner with high growth potential and a leading cost position in the fast-growing concentration solar power sector."
Besides the Imperial Valley solar farm, Stirling is also proposing to build a similar-sized array of mirrored dishes that capture and concentrate the sun's rays and make electricity in the Mojave Desert. The company calls its system, something pioneered in New Mexico at the U.S. Department of Energy's Sandia National Laboratories, the SunCatcher.
That Mojave Desert project is intended to supply Southern California Edison, supplier of power to much of the region, including Riverside County and part of Orange County.
SDG&E supplies electricity to San Diego County and southern Orange County.
When fully built out, the two plants would combine to generate 1,750 megawatts ---- more than a third of what San Diego County residents use on a hot summer day.
Power-line opponents agree solar is a largely untapped resource, but they contend it is too costly and damaging to the environment to build massive solar farms in the desert and huge transmission lines to send the electricity they produce to Southern California's cities.
One such opponent, David Hogan of the Center for Biological Diversity, added that the solar technology being touted has yet to make the leap from the laboratory to large-scale commercial use and suggested the Imperial Valley plant is far from a sure thing.
"The Stirling project is desert mirage," Hogan said.

Have you not done your research and seen the writing on the wall? LNG facility on the coast of baja, importing foreign fossil fuel, continuing our dependance on other nations for our energy. Second, the powerlines going nearly to the border to existing and future Mexican power plants which have much more lax environmental standards than our power plants. SDGE/Sempra are heavily invested int fossil fuels and their transport! You are doing the citizenry a diservice telling them,"gee whiz why are people oppossing the largest solar array in So Cal?". Finally even if Stirling Solar or it's irish successor weren't simply a token glitch-laden beta prototype, crossing through a state, national or local park is as unsustainable and ungreen as you can get. enough already!

As of last month, the estimate was that the project application would be filed at the CEC by June 2008. The El Centro office of the U.S. Bureau of Land management is currently reviewing an environmental assessment (EA) provided by SES for geotechnical testing associated with the solar project for SDG&E. This is SES's second try. The previous EA was rejected by the BLM. If this EA is judged adequate, the BLM will put the document out for public comment. If you'd like to be notified when the public comment period starts, call the El Centro BLM at (760)337-4400 and ask to be put on the notification list.

GreenFuture wrote on Apr 18, 2008 9:27 AM:This is great news for San Diego! How can people who claim to be environmentalists oppose this project? They should be doing everything in their power to help make it a reality! I think thy are more interested in hurting Sempra than they are in truly helping the environment. I challenge them to examine their motives.
