Sempra Generation has selected Suntech and Zachry to design and construct the Mesquite Solar 1 project in Arizona, US.

Under the contract, Zachry will be responsible for the installation and integration of more than 800,000 Suntech multi-crystalline solar panels at the site.

The construction of the plant will start in mid-2011 and completed by 2013, generating 350,000MWh of electricity every year, which is sufficient to power 50,000 homes.

The power generated from the plant will be sold to Pacific Gas & Electric under a 150MW (AC), 20-year power purchase agreement to be approved by California Public Utilities Commission.
