Located in Arlington, Ariz., about 40 miles west of Phoenix, Mesquite Solar 1
is part of Sempra U.S. Gas & Power's massive 4,000-acre Mesquite Solar
complex, with the potential to build out up to 700 MW of capacity. The
Mesquite Solar Complex is well-positioned to be North America's largest
photovoltaic (PV) solar power installation.

"Mesquite Solar 1 represents a major step forward for the state of Arizona as
we continue down the path toward our goal of establishing ourselves as the
nation's leader in solar generation," said Bennett."Sempra U.S. Gas and Power
has demonstrated remarkable leadership with this project, and we look to
continue working together to fully build-out the Mesquite Solar Complex."

"This is a shining moment for the state of Arizona as it continues to
establish itself as a renewable energy leader," said Kevin C. Sagara, vice
president of renewables for Sempra U.S. Gas & Power. "There is so much to be
proud of here.Our project would not have been possible without all the
tremendous support we received at the federal, state and local level." 

Construction on Mesquite Solar 1 began in June 2011.The solar project
provided a boost to the local economy by creating more than 500 local
construction jobs at peak along with 10 long-term positions. The landmark
solar plant was completed in December 2012 and now generates enough
emission-free electricity for about 56,000 homes. 

The renewable power from Mesquite Solar 1 is sold to Pacific Gas & Electric
under a 20-year contract.

Completion of Mesquite Solar 1 brings Sempra U.S. Gas & Power's operating
solar portfolio up to 300 MW. The company has another 308 MW under
construction at its Copper Mountain Solar 2 and Copper Mountain Solar 3
facilities in Boulder City, Nev.
