In 2024 it served 11,432 bundled residential customers in Arizona, and its average realised residential price was 19.49 cents per kWh: $25 million of residential revenue divided by 126,426 MWh of residential sales.

Across the other sectors, USBIA-San Carlos Project's 2024 average prices were 17.93 cents for commercial customers (1,907 accounts) and 15.69 cents for industrial customers (2 accounts). Industrial customers paid 3.80 cents less per kWh than households, a 19% discount that is typical of high-volume, high-voltage service.

Within Arizona, USBIA-San Carlos Project ranked number 12 of 21 utilities with bundled or delivery service by residential accounts served (11,432) and accounted for 0.31% of the state's residential electricity sales in 2024, measured in MWh sold or delivered rather than in customers. The state-wide average realised residential price in 2024, computed from the same EIA file, was 14.91 cents per kWh, so USBIA-San Carlos Project's customers paid 4.58 cents above the Arizona average (+30.7%). For context, EIA's latest monthly figure for Arizona is 15.18 cents per kWh (June 2026, Electric Power Monthly); that is a different, more recent measure across all utilities and is not directly comparable with a 2024 annual average.

On the grid side it operates in the WECC NERC region, and reported buying transmission, distribution, wholesale marketing, and retail marketing as its activities. Balancing authority code: WALC.
