UniSource Energy Services

What UniSource Energy Services does

UniSource Energy Services is a regulated electric and natural gas utility serving approximately 260,000 customers across northern and southern Arizona. The company distributes electricity to roughly 98,000 customers in Mohave and Santa Cruz counties through 3,600 circuit-miles of distribution lines, 338 circuit-miles of transmission lines, and 40 substations spanning 8,056 square miles, and delivers natural gas to roughly 162,000 customers across Santa Cruz, Mohave, Yavapai, Coconino, and Navajo counties through 4,200 miles of distribution piping and 31 miles of transmission mains across 1,400 square miles. UniSource reported a 99.9% electric reliability rate with an average of 64 minutes without power per customer last year, and operates from eight local offices across seven Arizona cities under a Tucson corporate headquarters.

The company generates revenue primarily through regulated, recurring tariff-based charges: fixed Basic Service Charges plus usage-based delivery and supply charges, with multiple residential electric pricing plans including Basic, Time-of-Use, Peak Demand, and Demand TOU, and gas tariffs segmented by Residential, Small Volume Commercial, and Large Volume Industrial tiers. Additional revenue comes from regulatory surcharges including PPFAC, REST, DSM, LFCR, TCA, SRB, and Regulatory Expense Surcharge, though the REST surcharge was eliminated when the Arizona Corporation Commission repealed the state's Renewable Energy Standard in March 2026. UniSource also operates the My Account online portal and UniSource mobile app, which integrate with Nest and ecobee thermostats, support outage reporting, and provide hourly and monthly energy usage data.

Beyond commodity delivery, UniSource has built a portfolio of customer-facing programs including the CARES low-income discount program ($16/month electric discount, $5 plus 40% PGA discount for gas), the Efficient Home rebate program (up to $450 for heat pumps) delivered through Franklin Energy, the GoSolar Shares community solar program, the Smart EV Charging Program for commercial and multi-family infrastructure, and the Power AZ assistance program launched in March 2026. UniSource is a privately held subsidiary of UNS Energy Corporation and receives regulatory oversight from the Arizona Corporation Commission for all rates and major infrastructure investments.
