Shareholders of UniSource Energy Corp. have approved changing the company's name to UNS Energy Corp.
The company's new name and a new logo are intended to strengthen its brand identity and to differentiate it from unrelated companies with similar names, it said.
The name "UniSource Energy" was introduced in 1998 in anticipation of industry deregulation, which did not materialize as envisioned.
UniSource Energy's primary subsidiaries include Tucson Electric Power (TEP), which serves more than 405,000 customers in southern Arizona, and UniSource Energy Services (UES), provider of natural gas and electric service for about 240,000 customers in northern and southern Arizona.
