Amber = the grid region's average demand (GW, left). Red = the state's residential rate (¢/kWh, right). The rate line ends a couple months early because EIA reports retail data on a lag.

Homes vs. industry

Arizona · ¢/kWh

What households pay (red) vs. large industrial users (dashed). The shaded band is the gap — the affordability story behind data-center load growth.

Most of Arizona's power runs through Arizona Public Service, where grid demand rose 35% over the same period — a signature of the always-on, data-center-driven load reshaping the grid.

EIA derives the rate as revenue ÷ electricity sold — a proxy, not a surveyed tariff. Rates rise for many reasons (fuel costs, grid upgrades, storms), not data centers alone, so this shows correlation, not causation. Note the rate is a statewide residential average while the demand is the regional grid operator's — related, but not the same geography.
