San Diego, December 27, 2011 — Sempra Generation announced that three blocks of solar panels totaling 42 MW have been installed at its Mesquite Solar 1 project and are now delivering renewable electricity to the power grid.
Construction on the 150-MW photovoltaic solar installation in Arlington, Ariz., located about 40 miles west of Phoenix, began in June 2011. Sempra Generation anticipates that the project will be completed in early 2013.
Power from the facility is sold to Pacific Gas and Electric Co. under a long-term, 20-year contract.
The progress at Mesquite Solar 1 moves Sempra Generation closer to its goal of adding 1,000 MW of renewables to its power generation portfolio by 2015. Since announcing the target in early 2011, the company has installed, started construction or secured long-term utility contracts for more than 500 MW of additional solar and wind capacity.
About 450 construction workers are currently on-site at Mesquite Solar 1 and installing an average of 4,500 photovoltaic solar panels each day. The 900-acre facility, which would cover 680 football fields, will employ more than 800,000 panels to generate enough electricity for about 50,000 homes at full build-out.
Mesquite Solar 1 is the first phase of Sempra Generation's Mesquite Solar Complex, a facility that could grow to 700 MW. Concurrently, the company is constructing a second 150-MW solar plant in Boulder City, Nev. called Copper Mountain Solar 2. The electrical output from that project is also fully contracted for 25 years to PG&E.
