600 MW Arizona Solar Power Plant Planned

When it comes to solar power, Sempra Generation isn’t messing around. Not long after their massive Copper Mountain Solar Facility in Nevada went online, the company has announced that, through a subsidiary, it has entered into a 20-year power-purchase agreement with Pacific Gas & Electric (PG&E) to sell 150 megawatts (MWs) of solar power produced at its Mesquite Solar I project in Arizona.

In keeping with Sempra’s ambitious renewable energy goals, Mesquite Solar I is the first phase of an overall solar complex planned for the Arlington area (about 40 miles west of Phoenix). The company currently owns or controls enough land to build up to 600 MWs of solar power at the site, which would make it the largest photovoltaic solar power plant in North America. (Eclipsing the scale of the Copper Mountain Complex in Nevada, also owned by Sempra.)

The Mesquite solar installation is slated to connect to the power grid at the Hassayampa switchyard, located nearby. This switchyard is a major energy hub to consumer markets throughout the Western U.S. (including, we assume, both southern California and Las Vegas).  Upon completion in early 2013, Mesquite Solar I will produce enough juice to power approximately 56,000 American homes.
