Ryan Companies US, Inc. Selected To Build UniSource Energy Headquarters

Downtown Tucson Skyline to Gain First High Rise Building in Over 20 Years

PHOENIX (November 23, 2009) – Ryan Companies US, Inc., one of the Valley’s largest
developers and design builders of commercial and office properties, was selected in a highly competitive process to develop an approximately 150,000 square-foot corporate headquarters for UniSource Energy Corporation (NYSE: UNS) in the heart of downtown Tucson.

“After considering many options, Ryan was the clear choice for its ability to provide quality and reliability at a fair price – values we embrace in our own operations,” said Paul Bonavia, UniSource Energy’s Chairman, President and CEO.

UniSource Energy, the largest publicly traded company based in Tucson, provides electric service and natural gas to more than 635,000 Arizona customers through subsidiaries Tucson Electric Power (TEP) and UniSource Energy Services (UES).

The building is expected to be completed by the fourth quarter of 2011 on a two-acre site at Broadway Boulevard and Scott Avenue. Ryan will seek the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) Certification at the Gold or Platinum level for the building through energy-efficient construction techniques and environmentally sensitive design.

“TEP is committed to energy efficiency and environmental stewardship, and the construction of our new headquarters gives us an opportunity to lead by example,” Bonavia said. “We’ll also be able to consolidate our staff and make other improvements to our working space that will help us do business more efficiently and effectively.”

As the Developer and General Contractor, Ryan will be utilizing its in-house Design-Build services in conjunction with subcontractors to build the shell and interiors; local companies will be given preference in the bidding for construction contracts. A select group of Arizona architects is being considered for the building’s design.

“This project is a significant development not only for Ryan Companies but also for the City of Tucson,” notes Todd Holzer, vice president of Ryan’s Southwest operation. “We look forward to building a lasting relationship with both the City of Tucson and UniSource Energy.”
