First Solar Inc is going to develop a 48 MW photovoltaic power plant for Sempra Generation, a solar power plant operator. The new power plant is going to be located some 40 miles southeast of Las Vegas, Nevada. Together with another 10 MW solar power plant already completed by First Solar in 2008, also for Sempra, the total installed solar power capacity of 58 MW will be the largest single PV power plant in North America. Both the existing and the new power plants will lie adjacent to the existing Sempra El Dorado Energy 480 MW power plant.

According to John Carrington, First Solar's executive vice-president, the company is pleased to have been chosen for such a large-scale solar power project, stating that this is proof that First Solar has the ability to provide a cost-effective energy solution for utility-scale projects.
