eSolar and Southern California Edison to Produce 245 MW of Solar Power Series of Pre-Fab Solar Plants To Provide Clean Electricity to Communities in Southern California

PASADENA, Calif.--June 3 2008 --Today, eSolar™, a producer of scalable solar thermal power plants, announced that it has signed a power purchase agreement with Southern California Edison (SCE) to build a total of 245 megawatts (MW) of concentrating solar plants in the Antelope Valley region of Southern California. The series of fully operational plants will begin production in 2011.

“SCE is committed to providing renewable energy generation at competitive costs – to this end, we review all of the possible sources to meet the growing demand for clean power,” said Stuart Hemphill, SCE vice president, Renewable and Alternative Power. “eSolar’s proposed solar projects promise to be modular, scalable, and easily and rapidly deployed. SCE is excited about the prospects of eSolar’s unique solar technology and the potential benefits it can bring for our customers.”

On the heels of its $130 million funding round in April led by Idealab, Google.org, and Oak Investment Partners, eSolar is aggressively pursuing a novel approach to large or utility-scale solar projects. Leveraging a proprietary combination of optics and software in a pre-fabricated form factor, eSolar achieves economies of scale with a modular design that focuses on the key business obstacles that have characterized large solar installations – price, scalability, speed of deployment and grid impact.

“eSolar’s proprietary approach to solar thermal generation can be designed to meet the needs of utilities large and small – a smarter-sized footprint and variable configurations ensure power can be delivered where it is needed most,” said Asif Ansari, CEO of eSolar. “We are proud to be supporting SCE in its commitment to delivering clean, reliable electricity to its customers.”

About eSolar

eSolar is an Idealab company founded by CEO Asif Ansari in 2007 to develop, construct and deploy modular, scalable solar thermal power plants. eSolar’s approach marries a low-impact, pre-fabricated form factor with advanced optics and computer software engineering to meet the demands of utilities of any size for clean, renewable and cost-competitive solar energy. By focusing on the key business obstacles that have characterized large solar installations – price, scalability, speed of deployment and grid impact – eSolar has developed a proprietary solution to make a dramatic reduction in the cost of solar thermal technology. eSolar is based in Pasadena, California and has 76 employees.
