Tucson Electric Power
Tucson Electric Power Company (TEP), a wholly owned subsidiary of UNS Energy Corporation which is in turn owned by Fortis Inc. (TSX/NYSE: FTS) — one of North America's largest regulated electric and gas utilities — is the principal electric utility serving Tucson, Arizona and the surrounding Pima County region, providing reliable electricity to approximately 440,000 customers across the Old Pueblo metropolitan area. Founded in 1892 and serving Tucson's energy needs for more than 130 years, TEP operates a diverse generation fleet including coal, natural gas, solar, and wind power resources, providing electricity across its 1,155 square-mile service territory that encompasses one of the fastest-growing major metropolitan areas in the American Southwest. According to its website at tep.com, TEP is committed to providing safe, reliable, and affordable energy while pursuing an ambitious clean energy transition that is transforming its generation mix from fossil fuels to renewable energy sources.
TEP's clean energy transition program, described at tep.com, is one of the most ambitious of any medium-sized U.S. electric utility, with the company committed to reaching 100% clean and renewable energy by 2035 — retiring its coal generation and replacing it with a combination of utility-scale solar, wind, battery energy storage, and other clean energy resources that leverage Arizona's extraordinary solar resources and growing renewable energy infrastructure. Tucson's location in the Sonoran Desert — receiving approximately 350 days of sunshine per year — makes it one of the nation's premier locations for solar energy development, and TEP has pursued large-scale solar and battery storage projects that are rapidly increasing the solar share of its generation portfolio while also providing customers with increased reliability through energy storage. TEP's clean energy investments include both utility-scale solar and storage projects and expanded rooftop solar and demand response programs that engage customers in the clean energy transition.
TEP's Fortis Inc. ownership provides the Tucson utility with the financial resources, operational expertise, and regulatory affairs capabilities of a large North American regulated utility holding company that manages regulated utilities across Canada, the United States, and the Caribbean. According to tep.com, TEP's Fortis affiliation provides access to capital markets, best practices in utility operations, and experience navigating regulatory proceedings that support TEP's significant capital investment program in clean energy and grid modernization. Tucson Electric Power's combination of 130-year Tucson utility heritage, 100% clean energy 2035 commitment, exceptional Arizona solar resource, Fortis Inc. institutional backing, and essential metropolitan utility status establishes it as a distinctive and ambitious participant in Arizona's clean energy transformation.
