First Solar to Build 10 MW Solar PV Power Plant for Sempra Generation

TEMPE, Ariz.--(BUSINESS WIRE)--First Solar, Inc. (Nasdaq:FSLR) announced today that it will build a 10 megawatt (MW) photovoltaic (PV) power plant for Sempra Generation near Boulder City, Nevada. First Solar will design, engineer and construct the turnkey PV power plant and will provide monitoring and maintenance services for the plant over its lifetime. Sempra Generation will be the developer for the project, and will own and operate the PV power plant once completed. Construction began in July, and the 10 MW PV power plant is expected to be completed by the end of 2008. The solar modules to be deployed in this ground-mount project will be produced at First Solar’s manufacturing facility in Perrysburg, Ohio.

“This new solar project is another step in Sempra Generation’s long-range plan to emerge as a leading renewable-energy developer”

“Sempra Generation has a proven track record for successful energy resource development and we are pleased to work with them to bring additional renewable electric generation to the region,” said Mike Ahearn, chief executive officer of First Solar. The 10 MW PV power plant will be adjacent to Sempra Generation’s existing El Dorado combined cycle natural gas plant. By co-locating this new PV power plant with existing infrastructure and the associated interconnection and transmission facilities, Sempra Generation will maximize their land and transmission. As a result, the impact to the immediate environment is minimal and the project completion timeline will be shorter. The PV power plant will serve customers in California and the Western United States.

“This new solar project is another step in Sempra Generation’s long-range plan to emerge as a leading renewable-energy developer,” said Michael W. Allman, president and chief executive officer of Sempra Generation. “The combination of Sempra Generation’s experience in developing power-generation projects in the region with First Solar’s expertise in advanced, thin-film photovoltaic solutions is a natural fit. ”

First Solar is the cost leader in the solar PV industry, driven by an advanced thin film semiconductor manufacturing process. At the end of 2007, over 300 MW of First Solar PV modules had been installed worldwide and First Solar expects to ship 420 to 460 MW of PV modules in 2008. Together with its project partners, First Solar modules have been deployed in several of the largest ground and rooftop PV power plants in the world.
