Tucson Electric Power / Unisource Energy

Tucson Electric Power provides the energy behind Tucson's economy. We deliver safe, reliable power to more than 417,000 customers in the Tucson metropolitan area.

And we're more than a utility. We’re also a local leader in community service, volunteerism and economic development efforts.

TEP and its sister company, UniSource Energy Services, are among a family of utilities owned by Fortis, Canada’s largest investor-owned gas and electric utility holding company. Fortis completed an acquisition of UNS Energy, TEP’s and UES’ parent company, in August 2014.

TEP offers comprehensive energy services through reliable, traditional resources and a growing renewable power portfolio. We also offer many ways to help our customers use energy more efficiently.

TEP's community service efforts have earned nationwide acclaim. We provide direct contributions and other support for our employees' volunteerism, encouraging a spirit of giving that is shared among the Fortis family of utilities.
