When a company has not only survived, but excelled for more than two centuries, that company is doing something right. Not only lasting, but growing (and exponentially so), requires the ability to evolve with the times via a continual quest for improvement. This approach is the current that has energized Tucson Electric Power (TEP) since the late 1800s. Today, this principal subsidiary of UniSource Energy Corporation generates and transmits electricity to more than 400,000 customers in Southern Arizona.
